Description

本発明は、ガスや液化ガス等を蓄える圧力容器及びその製造方法に関し、詳しくは所定の搭載スペースを有効に利用し得る扁平圧力容器及び扁平圧力容器の製造方法に関するものである。   The present invention relates to a pressure vessel that stores gas, liquefied gas, and the like and a manufacturing method thereof, and more particularly to a flat pressure vessel that can effectively use a predetermined mounting space and a manufacturing method of the flat pressure vessel.

内部にガスや液化ガス等を蓄える圧力容器にあっては、例えば、ＬＰＧ（液化石油ガス）やＣＮＧ（圧縮天然ガス）等の高圧ガスを燃料とする自動車の燃料タンクに利用されている（図１５（イ）参照）。このような燃料タンク用の圧力容器としては、図１７（イ）のように、円筒形状の胴部７１の両開口に、半球状の鏡部７２が連成されたシリンダー形状の圧力容器（以下、シリンダー型圧力容器）７０が一般的である。尚、このシリンダー型圧力容器７０は、強度や充填容量等の、圧力容器に必要な特性を充分に満足できる適正な形状である。   In a pressure vessel that stores gas, liquefied gas, or the like, it is used, for example, in a fuel tank of an automobile that uses high pressure gas such as LPG (liquefied petroleum gas) or CNG (compressed natural gas) as fuel (see FIG. 15 (a)). As a pressure vessel for such a fuel tank, as shown in FIG. 17 (a), a cylindrical pressure vessel (hereinafter referred to as a cylindrical pressure vessel) in which a hemispherical mirror portion 72 is coupled to both openings of a cylindrical barrel portion 71. Cylinder type pressure vessel) 70 is common. The cylinder pressure vessel 70 has an appropriate shape that can sufficiently satisfy the characteristics required for the pressure vessel such as strength and filling capacity.

ここで、ＬＰＧやＣＮＧを燃料とする自動車にあって、燃料タンクである圧力容器は、車体下部やトランク等に設けられた比較的限られた搭載スペースに配置されるようになっている（図１５（イ）参照）。この搭載スペースは、奥行きが深くかつ高さが低い略直方体状である場合が多い。そのため、上記したシリンダー型圧力容器は、複数本を該搭載スペースに並列状態で配置される。しかし、このような略直方体状の搭載スペースでは、シリンダー型圧力容器の積載可能本数が該スペースの寸法により制限を受けると共に、該圧力容器のシリンダー形状と搭載スペースの略直方体状との隙間、いわゆるデッドスペースが比較的大きくなる（図１７（ロ）、（ハ）参照）。而して、搭載スペースの体積に対する、搭載された圧力容器に充填できる最大充填容量の割合、いわゆる燃料の積載効率が低いという問題があった。   Here, in a vehicle using LPG or CNG as fuel, a pressure vessel as a fuel tank is arranged in a relatively limited mounting space provided in a lower part of a vehicle body, a trunk, or the like (see FIG. 15 (a)). In many cases, the mounting space has a substantially rectangular parallelepiped shape with a deep depth and a low height. Therefore, a plurality of the cylinder type pressure vessels described above are arranged in parallel in the mounting space. However, in such a substantially rectangular parallelepiped mounting space, the number of cylinder pressure vessels that can be loaded is limited by the size of the space, and the clearance between the cylinder shape of the pressure vessel and the substantially rectangular parallelepiped shape of the mounting space, so-called The dead space becomes relatively large (see FIGS. 17B and 17C). Thus, there is a problem that the ratio of the maximum filling capacity that can be filled in the mounted pressure vessel with respect to the volume of the mounting space, that is, the so-called fuel loading efficiency is low.

このような燃料の積載効率を改善するため、例えば、図１８（イ）のように、上記のシリンダー形状の一周部を長手方向に沿って平面とする片側扁平形状の側型胴部７９及び側型鏡部８０を備えた側型圧力容器７７，７７と、シリンダー形状の対向する両側の周部を長手方向に沿って平面とした両側扁平形状の内型胴部８１及び内型鏡部８２を備えた内型圧力容器７８とを、内型圧力容器７８の両平面に側型圧力容器７７，７７の各平面が重なるように接合し、全体として略扁平形状の複合型圧力容器７５が提案されている（例えば、特許文献１）。このような扁平形状の複合型圧力容器７５を、上述した搭載スペースＦに搭載すると、シリンダー型圧力容器を複数本搭載した場合（図１７（ロ）参照）に比して、デッドスペースＸを減少することとなる（図１８（ロ）参照）。而して、ガスの最大充填容量が増加し、燃料の積載効率が向上することとなる。
米国特許第５５７７６３０号明細書 In order to improve the fuel loading efficiency, for example, as shown in FIG. 18 (a), the one-side flat-shaped side mold body 79 and the side having the one-round portion of the cylinder shape as a plane along the longitudinal direction. Side-type pressure vessels 77 and 77 having a mold mirror part 80, and a cylindrical inner mold body 81 and an inner mold mirror part 82 which are flat on both sides of the cylinder-shaped opposite sides are flat along the longitudinal direction. The inner pressure vessel 78 provided is joined so that both planes of the side type pressure vessels 77, 77 overlap with both planes of the inner pressure vessel 78, and a generally flat combined pressure vessel 75 is proposed. (For example, Patent Document 1). When such a flat composite pressure vessel 75 is mounted in the mounting space F described above, the dead space X is reduced as compared with the case where a plurality of cylinder pressure vessels are mounted (see FIG. 17B). (See FIG. 18 (b)). Thus, the maximum filling capacity of gas is increased, and the fuel loading efficiency is improved.
US Pat. No. 5,577,630

ところで、自動車の燃料は、充填一回当りの走行距離を伸ばすため、制限された搭載スペースにできるだけ多く積載できることが望ましい。そのため、上述した従来の、側型圧力容器と内型圧力容器とからなる複合型圧力容器は、シリンダー型圧力容器に比して最大充填容量を増加させたものである。しかしながら、この複合型圧力容器であっても、搭載スペースの体積に比して、燃料の積載効率が充分でなく、さらなる最大充填容量の増加が求められている。また、この複合型圧力容器は、同じ搭載スペースに、上述したシリンダー型圧力容器を搭載した場合に比して、全体として胴部の面積と鏡部の面積とが増加することとなるため、重量が増加するという問題が生じている。さらにまた、この複合型圧力容器は、側型圧力容器と内型圧力容器とがそれぞれ独立した容器として形成されているものであるから、各容器毎に、ガスを充填する充填バルブや排出する排出バルブ、内容量計等が設置されている。したがって、充填バルブや排出バルブを取り付ける各バルブ座や、内容量計を取り付けるための内容量計座等を、各容器に設置するための製造工程が必要となること、及び各部品費用と取り付け費用が生じることとなる。さらに、各バルブや内容量計等の設置数に従って重量が増加することとなる。これらは、製造工程の改善や容器自体の軽量化等を進めても低減できないという問題がある。一方、液化ガスを充填する複合型圧力容器にあっては、側型圧力容器と内型圧力容器とを連通する連通孔を、接合する平面に設けた場合でも、当該複合型圧力容器の搭載時において底部となる部位に該連通孔を設けなければ、内容量計は各容器毎に必要となる。また、充填バルブや排出バルブにあっても鏡部に配設されることから、各容器毎に必要である。さらに、このような連通孔を設けることは、容器の強度を保持する平面の強度低下や応力集中を招くこととなるという問題が生じる。   By the way, it is desirable that the fuel of the automobile can be loaded as much as possible in the limited mounting space in order to extend the travel distance per filling. For this reason, the above-described conventional composite pressure vessel including a side pressure vessel and an inner pressure vessel has an increased maximum filling capacity compared to a cylinder pressure vessel. However, even in this composite pressure vessel, the fuel loading efficiency is not sufficient as compared with the volume of the mounting space, and further increase in the maximum filling capacity is required. In addition, this composite pressure vessel has an increased body area and mirror area as a whole compared to the case where the above-described cylinder pressure vessel is mounted in the same mounting space. There is a problem that increases. Furthermore, in this composite type pressure vessel, the side type pressure vessel and the inner type pressure vessel are formed as independent vessels, so that a filling valve for filling gas and a discharge for discharging are provided for each vessel. Valves, internal volume meters, etc. are installed. Therefore, it is necessary to have a manufacturing process for installing each valve seat to which a filling valve and a discharge valve are attached, an inner capacity meter seat for installing an inner capacity meter, etc. in each container, and each component cost and installation cost. Will occur. Furthermore, the weight will increase according to the number of valves and internal volume meters installed. There is a problem that these cannot be reduced even if the manufacturing process is improved or the weight of the container itself is reduced. On the other hand, in the case of a composite pressure vessel filled with liquefied gas, even when a communication hole for communicating the side type pressure vessel and the inner type pressure vessel is provided on the joining plane, If the communication hole is not provided in the bottom part of the container, an internal volume meter is required for each container. Moreover, even if it exists in a filling valve and a discharge valve, since it is arrange | positioned in a mirror part, it is required for every container. Furthermore, the provision of such a communication hole causes a problem that the strength of the plane that retains the strength of the container is reduced and the stress is concentrated.

一方、このような複合型圧力容器にあっては、該側型圧力容器と内型圧力容器を夫々に成形した後、接合して一体的に製造されるものである。したがって、接合作業を容易とするために、例えば、側型圧力容器の平面に接合用の凸部が形成されると共に、内型圧力容器の両平面に夫々に接合用の凹部が形成され、内型圧力容器の凹部に、側型圧力容器の凸部を嵌合して接合するようにしている。ところが、このような接合用の凹部及び凸部を形成するために新たな工程が必要となることから、容器の製造工程が繁雑化すると共に、製造費用も増大することとなる。   On the other hand, in such a composite pressure vessel, the side-type pressure vessel and the inner-type pressure vessel are respectively molded and then integrally joined. Therefore, in order to facilitate the joining operation, for example, a convex portion for bonding is formed on the plane of the side pressure vessel, and a concave portion for bonding is formed on each plane of the inner pressure vessel. The convex portion of the side pressure vessel is fitted and joined to the concave portion of the mold pressure vessel. However, since a new process is required to form such a concave part and a convex part for joining, the manufacturing process of the container becomes complicated and the manufacturing cost also increases.

本発明は、上述した問題を解決し、燃料の積載効率をさらに向上でき、また、比較的容易に製造可能な、扁平圧力容器及び扁平圧力容器の製造方法を提案することを目的とするものである。   An object of the present invention is to propose a flat pressure vessel and a flat pressure vessel manufacturing method that can solve the above-described problems, can further improve fuel loading efficiency, and can be manufactured relatively easily. is there.

本発明は、内部を、縦断隔壁により区画して長手方向に沿った複数の筒状主貯留域を幅方向へ並成してなる両端が開口する扁平円筒胴部と、該扁平円筒胴部の両端開口を覆って接合され、内部に各主貯留域を連通する連通領域を形成する皿状鏡部とで構成され、所定のガス又は液化ガスを容器内に充填する充填バルブ及び容器外に排出する排出バルブを少なくとも各一個備えてなるか、又は、充填と排出とを行う入出バルブを少なくとも一個備えてなるものであることを特徴とする扁平圧力容器である。ここで、本発明の扁平圧力容器は、幅方向に扁平化された形態としたものである。また、本発明の扁平圧力容器には、所定のガス又は液化ガスを充填する機能と排出する機能とを有していれば良い。すなわち、充填バルブ及び排出バルブをそれぞれ少なくとも一個備える構成か、又は、充填及び排出の両方を一個のバルブで行う入出バルブを少なくとも一個備える構成のいずれかとするものである。尚、充填バルブ及び排出バルブ、入出バルブを混在させることも可能である。さらに、ガス充填量を目視するための内容量計を設ける場合にあっても、少なくとも一個設けるだけで良いという優れた利点を有する。   The present invention includes a flat cylindrical body having both ends opened by dividing a plurality of cylindrical main storage areas along the longitudinal direction by dividing the inside by a longitudinal partition wall, and both ends of the flat cylindrical body It consists of a dish-shaped mirror that is joined to cover the openings at both ends and forms a communication area that communicates with each main storage area. It is filled with a predetermined gas or liquefied gas inside the container and discharged outside the container. It is a flat pressure vessel characterized in that it comprises at least one discharge valve to perform or at least one input / output valve for filling and discharging. Here, the flat pressure vessel of the present invention is configured to be flattened in the width direction. Moreover, the flat pressure vessel of this invention should just have the function to fill with predetermined | prescribed gas or liquefied gas, and the function to discharge | emit. That is, either a configuration including at least one filling valve and a discharge valve or a configuration including at least one input / output valve that performs both filling and discharging with one valve is employed. It is possible to mix a filling valve, a discharge valve, and an inlet / outlet valve. Furthermore, even in the case where an internal volume meter for visually checking the gas filling amount is provided, there is an excellent advantage that it is only necessary to provide at least one.

かかる構成にあっては、扁平円筒胴部の内部で区画された複数の筒状主貯留域が、皿状鏡部の内部の連通領域で連通し、容器全体の内部貯留域を一体形態としたものであるから、上述した略直方体状の搭載スペースに搭載した場合に、皿状鏡部が配されるスペースに生じるデッドスペースは、上述した従来の側型圧力容器と内型圧力容器とを接合した複合型圧力容器の各鏡部が配された場合に比して、減少することとなる。すなわち、皿状鏡部の連通領域は、従来の複合型圧力容器の各鏡部の内部領域を合計した領域に比して、ガスの貯留可能な容量が大きくなる。而して、本発明の扁平圧力容器は、上述した従来の、複合型圧力容器のように各圧力容器毎に鏡部を有する構成に比して、容器全体の最大充填容量が増加し、略直方体状の搭載スペースに対する、燃料ガスの積載効率を向上させることができる。   In such a configuration, the plurality of cylindrical main storage areas partitioned inside the flat cylindrical body part communicate with each other in the communication area inside the dish-shaped mirror part, and the internal storage area of the entire container is integrated. Therefore, the dead space generated in the space where the dish-shaped mirror portion is disposed when mounted in the above-described substantially rectangular parallelepiped mounting space joins the above-described conventional side-type pressure vessel and inner-type pressure vessel. As compared with the case where each mirror part of the combined pressure vessel is arranged, the number of the pressure parts is reduced. In other words, the communication area of the dish-shaped mirror portion has a larger gas storage capacity than the total area of the mirror regions of the conventional composite pressure vessel. Thus, the flat pressure vessel of the present invention increases the maximum filling capacity of the entire vessel as compared to the conventional configuration described above, which has a mirror part for each pressure vessel, and substantially The fuel gas loading efficiency with respect to the rectangular parallelepiped mounting space can be improved.

さらに、本発明の扁平圧力容器の皿状鏡部は、従来の複合型圧力容器の各容器毎の鏡部の総表面積に比して、その表面積が小さくなることから、容器重量が軽量化することともなり得る。また、本発明の扁平圧力容器は、上述のように容器全体の内部貯留域を一体形態としたものであるため、充填バルブと排出バルブとを少なくとも各一個配設するか、入出バルブを少なくとも一個配設するだけで良い。これに対して、上述した従来の複合型圧力容器は、各容器毎に充填バルブ及び排出バルブ又は入出バルブを配設する必要があることから、該複合型圧力容器に比して、本発明の扁平圧力容器は各バルブの配設数を減少でき、これに応じて軽量化することとなる。このように、本発明の扁平圧力容器は、従来の複合型圧力容器に比して、ガスの最大充填量を増加し、かつ軽量化したものである。   Furthermore, the dish-shaped mirror part of the flat pressure vessel of the present invention has a smaller surface area than the total surface area of the mirror part for each container of the conventional composite pressure vessel, thus reducing the weight of the container. It can be a problem. In addition, since the flat pressure vessel of the present invention has the internal storage area of the entire vessel integrated as described above, at least one filling valve and one discharge valve are provided, or at least one input / output valve is provided. It is only necessary to arrange them. On the other hand, the conventional composite pressure vessel described above requires a filling valve and a discharge valve or an inlet / outlet valve for each container. In the flat pressure vessel, the number of valves can be reduced, and the weight is reduced accordingly. As described above, the flat pressure vessel of the present invention increases the maximum gas filling amount and is lighter than the conventional composite pressure vessel.

また、筒状主貯留域を区画形成する縦断隔壁は、該扁平円筒部が充填したガスの内圧に対する強度や耐久性の向上と、外部から受ける負荷に対する強度や耐久性の向上とを図るための補強壁としても働き、当該扁平圧力容器が充分な強度と耐久性を発揮できるようにしている。   In addition, the longitudinal partition wall that defines the cylindrical main storage area is for improving the strength and durability against the internal pressure of the gas filled in the flat cylindrical portion and improving the strength and durability against the load received from the outside. It also works as a reinforcing wall so that the flat pressure vessel can exhibit sufficient strength and durability.

また、上記のように、本発明の扁平圧力容器は内部が一体形態であることから、ガスの充填や排出を容器全体で行うこととなるため、ガスを充填したり排出したりする作業性が、上述した従来のシリンダー型圧力容器とほぼ同等であるという優れた利点も有する。   In addition, as described above, since the flat pressure vessel of the present invention has an integrated inside, the filling and discharging of the gas is performed in the entire vessel, so that the workability of filling and discharging the gas is improved. Also, it has an excellent advantage that it is almost equivalent to the above-described conventional cylinder type pressure vessel.

上述した扁平円筒胴部が、円弧の占める角度が１８０度以上の欠円状をなす断面円弧形状の長尺の側部円弧壁と、その欠円開口を覆う縦断隔壁とにより囲繞されて形成された、両側の筒状側部主貯留域を備えている構成が提案される。かかる構成にあっては、断面円弧形状が、円弧の角度が１８０度以上であり、かつ欠円状をなす側部円弧壁により形成されているものであるから、当該扁平円筒胴部は、１８０度以上の角度からなる領域だけ幅方向に扁平化されているものと言える。したがって、扁平円筒胴部は、上述したシリンダー型圧力容器に比して、１８０度以上の角度からなる領域の容積分だけ最大充填量が増加する。さらに、この扁平化に応じて、皿状鏡部の連通領域が形成されることから、該連通領域の容積も増える。而して、上述した従来の複合型圧力容器に比して、ガスの積載効率が向上する。   The above-described flat cylindrical body is formed by being surrounded by a long side circular arc wall having a circular arc shape with a circular arc shape with an angle occupied by the circular arc of 180 degrees or more and a vertical partition wall covering the cut circular opening. In addition, a configuration including cylindrical side main storage areas on both sides is proposed. In such a configuration, since the cross-sectional arc shape is formed by the side arc wall having a circular arc angle of 180 degrees or more and a circular shape, the flat cylindrical body portion is 180 °. It can be said that only a region having an angle of at least an angle is flattened in the width direction. Therefore, the maximum filling amount of the flat cylindrical body portion is increased by the volume of a region having an angle of 180 degrees or more, as compared with the above-described cylinder type pressure vessel. Furthermore, since the communication region of the dish-shaped mirror portion is formed according to the flattening, the volume of the communication region increases. Thus, gas loading efficiency is improved as compared with the above-described conventional composite pressure vessel.

さらに、かかる構成にあっては、欠円状をなす断面円弧形状の側部円弧壁を両側に備えたものであるから、該側部円弧壁により、扁平円弧胴部の幅方向（扁平方向）に対して、充分な剛性と強度とを発揮できる。さらに、この側部円弧壁は、扁平円弧胴部の高さ方向に対しても高い剛性と強度を有し、加えて縦断隔壁により、この高さ方向に対して充分な剛性と強度を発揮できることとなる。ここで、かかる扁平圧力容器について、ＦＥＭによる強度計算を行った結果、高圧ガス保安法の容器保安規則によるシリンダー型圧力容器の強度計算結果から得た板厚と、同等の板厚により強度設計可能であることが確認できた。而して、側部円弧壁と縦断隔壁とにより囲繞されて形成された、両側に筒状側部主貯留領域を備える扁平円筒胴部にあっても、上述した従来のシリンダー型圧力容器と同様の、優れた強度及び剛性と軽量化との両者を満足することができる。   Furthermore, in such a configuration, since the side circular arc walls having a circular arc shape having a cross-sectional shape are provided on both sides, the side circular arc walls allow the width direction (flat direction) of the flat circular arc trunk portion to be formed. In contrast, sufficient rigidity and strength can be exhibited. Furthermore, this side arc wall has high rigidity and strength in the height direction of the flat arc barrel, and in addition, the longitudinal partition wall can exhibit sufficient rigidity and strength in this height direction. It becomes. Here, as a result of strength calculation by FEM for this flat pressure vessel, strength design is possible with plate thickness equivalent to the plate thickness obtained from the strength calculation result of cylinder type pressure vessel according to the vessel safety rules of the High Pressure Gas Safety Act It was confirmed that. Thus, even in the flat cylindrical body having a cylindrical side main storage area on both sides formed by being surrounded by the side arc wall and the vertical partition wall, it is the same as the above-described conventional cylinder pressure vessel. Both excellent strength and rigidity and weight reduction can be satisfied.

また、上述した扁平円筒胴部が、相互に対峙する二面の縦断隔壁と、上下の円弧の占める角度が９０度以下である断面円弧形状の長尺の中間円弧壁とにより囲繞されて形成された筒状中間主貯留域と、該筒状中間主貯留域の両側の縦断隔壁と、円弧の占める角度が１８０度以上の欠円状をなす断面円弧形状の長尺の側部円弧壁とにより囲繞されて形成された、両側の筒状側部主貯留域とを備えている構成が提案される。かかる構成にあっては、両側の側部円弧壁により形成された筒状側部主貯留域の間に、筒状中間主貯留域を備えたものであり、該筒状中間主領域を形成する中間円弧壁だけ、さらに扁平化した形状となる。したがって、この扁平円筒胴部の扁平化に従って、皿状鏡部の連通領域の容積が増加することとなる。また、この中間円弧壁により、扁平円弧胴部の幅方向（扁平方向）に対して充分な剛性と強度とを発揮でき、かつ、扁平円弧胴部の高さ方向に対しても、縦断隔壁と共に充分な剛性と強度とを発揮できる。このような筒状中間主貯留域を有する構成の扁平圧力容器にあっても、上述と同様、高圧ガス保安法の容器保安規則に従ったシリンダー型圧力容器の計算結果と同等の結果が得られ、優れた強度及び剛性と軽量化との両者を満足することができるものである。   Further, the above-described flat cylindrical body is formed by being surrounded by two vertical partition walls facing each other and a long intermediate arc wall having a circular arc shape in which the angle of the upper and lower arcs is 90 degrees or less. A cylindrical intermediate main storage area, vertical partition walls on both sides of the cylindrical intermediate main storage area, and a long side circular arc wall having an arcuate cross-section with an arc of 180 degrees or more. The structure provided with the cylindrical side part main storage area of the both sides formed by surrounding is proposed. In such a configuration, a cylindrical intermediate main storage area is provided between the cylindrical side main storage areas formed by the side circular arc walls on both sides, and the cylindrical intermediate main area is formed. Only the intermediate arc wall has a flattened shape. Therefore, the volume of the communication region of the dish-shaped mirror portion increases as the flat cylindrical body portion is flattened. In addition, this intermediate arc wall can exhibit sufficient rigidity and strength in the width direction (flat direction) of the flat arc barrel, and also with the vertical partition wall in the height direction of the flat arc barrel. Can exhibit sufficient rigidity and strength. Even in a flat pressure vessel having such a cylindrical intermediate main storage area, a result equivalent to the calculation result of the cylinder type pressure vessel in accordance with the vessel safety rules of the High Pressure Gas Safety Law is obtained as described above. Both excellent strength and rigidity and weight reduction can be satisfied.

ここで、扁平円筒胴部が、隣り合う二面が相互に対峙するように並立された複数の縦断隔壁の、各隣り合う二面の縦断隔壁毎に、上下一対の中間円弧壁と囲繞されて形成されたことにより、並列状に連成された複数の筒状中間主貯留域および、両側端の縦断隔壁と側部円弧壁とにより囲繞されて形成された両側の筒状側部主貯留域を備えている構成が提案される。かかる構成にあっては、搭載スペースの寸法に従って、適当数の筒状中間主貯留域を有するものとすることができ、搭載スペースに応じた高いガス積載効率が発揮される。また、かかる構成にあっても、筒状中間主領域が上下の中間円弧壁と縦断隔壁とにより形成されていることから、扁平圧力容器の幅方向及び高さ方向に対してそれぞれ、充分な強度と剛性とを発揮できる。   Here, the flat cylindrical body is surrounded by a pair of upper and lower intermediate arc walls for each of the two adjacent vertical partition walls of a plurality of vertical partition walls arranged side by side so that two adjacent surfaces face each other. A plurality of cylindrical intermediate main storage areas that are coupled in parallel by being formed, and cylindrical side main storage areas on both sides that are formed by being surrounded by vertical partition walls and side arc walls on both ends. A configuration comprising is proposed. In such a configuration, an appropriate number of cylindrical intermediate main storage areas can be provided according to the size of the mounting space, and high gas loading efficiency corresponding to the mounting space is exhibited. Even in such a configuration, since the cylindrical intermediate main region is formed by the upper and lower intermediate arc walls and the vertical partition wall, sufficient strength is obtained in each of the width direction and the height direction of the flat pressure vessel. And rigidity.

また、上述した扁平円弧胴部が、側部円弧壁の断面円弧径と中間円弧壁の断面円弧径とを同径に形成してなるものである構成が提案される。かかる構成とすることにより、扁平円弧胴部を構成する全ての円弧壁を、同じ壁厚で、単位円弧長当りの剛性と強度とを同じにできる。したがって、軽量化のために壁厚を薄肉化した場合にあっても、扁平円弧胴部を、幅方向及び高さ方向の剛性と強度とのバランスに優れたものとなり、軽量化の効果も大きくなり得る。   Further, a configuration is proposed in which the above-described flat arc body is formed by forming the cross-section arc diameter of the side arc wall and the cross-section arc diameter of the intermediate arc wall to be the same diameter. By adopting such a configuration, it is possible to make all the arc walls constituting the flat arc barrel portion have the same wall thickness and the same rigidity and strength per unit arc length. Therefore, even when the wall thickness is reduced for weight reduction, the flat arc barrel has an excellent balance between rigidity and strength in the width direction and height direction, and the effect of weight reduction is also great. Can be.

かかる製造方法にあっても、上述の製造方法と同様に、上述した本発明の筒状中間主貯留域と両側の筒状側部主貯留域とを備えた扁平圧力容器を容易かつ適正に製造することができる。この製造方法にあっては、比較的単純な形態である側部円筒壁、側部閉鎖円弧壁、中間双方壁及び皿状鏡部を別々に成形し、これらを溶接することにより、扁平圧力容器を製造するようにした方法である。ここで、扁平円筒部を、各々一個の側部円筒壁、側部閉鎖円弧壁、中間双方壁を接合することにより形成するようにしたから、成形工程で成形される部品点数を一層少なくでき、溶接箇所を減少できると共に溶接作業を単純化することができる。このため、成形工程と接合工程が簡素化され、製造効率を一層向上できると共に、各部品の保管場所を縮小することが可能である。而して、本扁平圧力容器の製造時間と製造にかかる費用とを低減することができる。また、縦断隔壁の接合部に円弧凹面が形成されていることにより、本製造方法で製造した扁平圧力容器に充填されたガスの内圧力や、充填と排出との繰り返し応力によって生じる応力集中を緩和できる。ここで、皿状鏡部の成形は、プレス加工により行うことが好適である。   Even in such a manufacturing method, similarly to the above-described manufacturing method, a flat pressure vessel including the above-described cylindrical intermediate main storage area of the present invention and the cylindrical side main storage areas on both sides is easily and appropriately manufactured. can do. In this manufacturing method, a flat cylindrical pressure vessel is formed by separately molding a side cylindrical wall, a side closed circular arc wall, both intermediate walls, and a dish-shaped mirror portion, which are relatively simple, and welding them. This is a method for manufacturing. Here, since the flat cylindrical portion is formed by joining one side cylindrical wall, side closed arc wall, and both intermediate walls, the number of parts molded in the molding process can be further reduced. The number of welding points can be reduced and the welding operation can be simplified. For this reason, the molding process and the joining process are simplified, the manufacturing efficiency can be further improved, and the storage location of each component can be reduced. Thus, it is possible to reduce the manufacturing time and manufacturing cost of the flat pressure vessel. In addition, the arc concavity is formed at the junction of the vertical partition walls, reducing the stress concentration caused by the internal pressure of the gas filled in the flat pressure vessel manufactured by this manufacturing method and the repeated stress of filling and discharging it can. Here, it is preferable that the dish-shaped mirror portion is formed by press working.

ここで、上記の製造方法にあって、接合工程が、中間双方壁の接合部に、中間円弧壁が連成されていない他側から、他の中間双方壁の上下の片側円弧端の接合端部を溶接することにより、複数の筒状中間主領域を連成する扁平円筒胴部を形成するようにした方法が提案される。かかる製造方法により、上述した本発明の、並列状に連成された複数の筒状中間主貯留域と両側の筒状側部主貯留域とを備えた扁平圧力容器を容易かつ適正に製造することができる。この製造方法にあっては、中間双方壁を複数成形して、順次溶接していくことにより、複数の筒状中間主貯留域を連成した扁平円筒胴部を容易に形成できる。このため、複数の筒状中間主貯留域を並成した扁平圧力容器を製造する場合にあって、部品点数と部品種類とを少くすることが可能である。また、予め中間双方壁を複数成形しておくことにより、当該扁平圧力容器の搭載される搭載スペースに応じた、幅方向の長さが異なる扁平圧力容器を、中間双方壁の接合数量を調整することによって容易かつ適切に製造することができるという利点もある。   Here, in the above manufacturing method, the joining step is a joining end of the upper and lower one-side arc ends of the other intermediate walls from the other side where the intermediate arc walls are not coupled to the joining portion of the both intermediate walls. A method is proposed in which a flat cylindrical body that is formed by coupling a plurality of cylindrical intermediate main regions is formed by welding the portions. By this manufacturing method, the flat pressure vessel having the plurality of cylindrical intermediate main storage areas and the cylindrical side main storage areas on both sides that are coupled in parallel according to the present invention described above is easily and appropriately manufactured. be able to. In this manufacturing method, by forming a plurality of both intermediate walls and sequentially welding them, it is possible to easily form a flat cylindrical body that is formed by coupling a plurality of cylindrical intermediate main storage areas. For this reason, in the case of manufacturing a flat pressure vessel in which a plurality of cylindrical intermediate main storage areas are arranged, it is possible to reduce the number of parts and the kind of parts. In addition, by forming a plurality of intermediate both walls in advance, the number of flat pressure vessels having different lengths in the width direction according to the mounting space in which the flat pressure vessels are mounted is adjusted. There is also an advantage that it can be manufactured easily and appropriately.

また、上述した成形工程が、側部円弧壁の断面円弧径と中間円弧壁の断面円弧径とを同径となるように成形した製造方法が提案される。かかる製造方法により、上述した本発明にかかる、全ての円弧壁が同じ円弧径からなる構成の扁平圧力容器を製造することができる。   Moreover, the manufacturing method which shape | molded so that the shaping | molding process mentioned above may become the same diameter as the cross-sectional arc diameter of a side part arc wall and the cross-sectional arc diameter of an intermediate | middle arc wall is proposed. With this manufacturing method, it is possible to manufacture a flat pressure vessel having a configuration in which all the arc walls according to the present invention have the same arc diameter.

また、上述の成形工程が、所定の扁平円筒胴部長さの略複数倍の長さに成形した後、所定長さに切断するようにした製造方法が提案される。かかる製造方法により、扁平円筒胴部を複数製造する場合に、この成形工程の効率が向上する。すなわち、比較的大量に製造する場合にあって、製造効率が向上することによって、製造時間と製造費用とを低減することができる。また、様々な長さの扁平円筒胴部を形成する場合にも、長さの異なる扁平圧力容器を容易に製造することができる。さらには、切断前の状態で保管しておくことにより、必要に応じて所望の長さの扁平圧力容器を製造できるという利点もある。   In addition, a manufacturing method is proposed in which the above-described forming step is formed into a length approximately a plurality of times the predetermined flat cylindrical body length, and then cut into a predetermined length. This manufacturing method improves the efficiency of this molding process when a plurality of flat cylindrical barrels are manufactured. That is, in the case of manufacturing in a relatively large amount, the manufacturing time and the manufacturing cost can be reduced by improving the manufacturing efficiency. Also, when forming flat cylindrical barrels of various lengths, flat pressure vessels having different lengths can be easily manufactured. Furthermore, there is also an advantage that a flat pressure vessel having a desired length can be manufactured as needed by storing it in a state before cutting.

このような製造方法にあって、成形工程により、縦断隔壁の接合部の外面に、長手方向に亘って嵌合凹溝を形成すると共に、該接合部に溶接される接合端部に、該嵌合凹溝に嵌入する嵌合凸部を形成し、接合工程により、前記接合部の嵌合凹溝に、接合端部の嵌合凸部を嵌入して溶接することにより接合するようにした方法が提案される。ここで、接合部の外面としては、縦断隔壁の壁厚方向に対向する側面や、扁平円筒胴部の高さ方向に対向する外表面のいずれとすることも可能である。接合端部は、上述した各製造方法にあって、側部円弧壁の欠円開口端や、中間片方壁、中間双方壁の円弧端の、縦断隔壁の接合部に溶接される部位を言う。かかる製造方法にあっては、接合部に形成された嵌合凹溝に、接合端部に形成された嵌合凸部を嵌入して溶接するようにしたことにより、接合工程における、接合位置の精度を向上できると共に、溶接作業の作業性を向上できる。また、所定の接合位置を常に適正な位置とすることができるから、各扁平圧力容器の固体間の差を減少することができる。   In such a manufacturing method, the forming process forms a fitting groove in the longitudinal direction on the outer surface of the joint portion of the longitudinal partition wall, and the fitting end is welded to the joint portion. A method of forming a fitting convex portion to be fitted into the mating groove, and joining the fitting concave groove of the joint portion by fitting and fitting the fitting convex portion of the joining end portion into the fitting concave groove in the joining step. Is proposed. Here, the outer surface of the joining portion may be any of a side surface facing the wall thickness direction of the longitudinal partition wall and an outer surface facing the height direction of the flat cylindrical body portion. The joining end portion refers to a portion welded to the joining portion of the longitudinal partition wall at the notch opening end of the side arc wall and the arc ends of the intermediate one side wall and the middle both walls in each manufacturing method described above. In such a manufacturing method, the fitting convex portion formed at the joint end portion is fitted into the fitting concave groove formed at the joint portion and welded, so that the joining position in the joining step can be reduced. Accuracy can be improved and workability of welding work can be improved. Moreover, since a predetermined joining position can always be an appropriate position, the difference between the solids of each flat pressure vessel can be reduced.

一方、上述した扁平圧力容器の製造方法にあって、成形工程が、アルミニウム合金を押出加工することにより成形するようにした製造方法が提案される。ここで、押出加工により成形するものとしては、上述した側部円弧壁、縦断隔壁、側部閉鎖円弧壁、中間片方壁、中間双方壁の扁平円筒胴部を形成する各部品である。尚、上述のように、皿状鏡部はプレス加工により成形することが望ましい。この押出加工にあっては、例えば、アルミニウム合金の板材から所定形状に成形する一般的なロール加工やプレス加工等の加工方法に比して、長尺部品の成形に適しており、該部品の形状及び寸法を高精度で成形でき、かつ加工工程を簡素化することができる。このため、成形工程に要する成形時間を短縮できると共に、成形費用を減少させることができる。特に、上述のように接合部に嵌合凹溝を設け、各壁の接合端部に嵌合凸部を設ける場合にあっては、板材から成形する方法に比して、精度を向上でき、かつ、成形加工費を低減できる。ここで、アルミニウム合金の押出加工としては、上述した製造方法にあって、側部円弧壁、縦断隔壁、中間片方壁、中間双方壁のような、いわゆるソリッド形状は比較的低い加工費用で成形できる。一方、側部閉鎖円弧壁のような、いわゆるホロー形状は、前記ソリッド形状に比して加工費が高くなる。したがって、接合工程における作業性と合わせて、製造される扁平圧力容器に用途に応じて、上述したような各製造方法を適宜選択すれば良い。   On the other hand, in the above-described flat pressure vessel manufacturing method, a manufacturing method is proposed in which the forming step is performed by extruding an aluminum alloy. Here, what is formed by extrusion processing is each component that forms the above-described flat cylindrical body portion of the side circular arc wall, the vertical partition wall, the side closed circular arc wall, the intermediate one side wall, and the both intermediate walls. As described above, the dish-shaped mirror part is desirably formed by press working. In this extrusion process, for example, it is suitable for forming a long part as compared with a processing method such as a general roll process or press process for forming an aluminum alloy sheet into a predetermined shape. The shape and dimensions can be formed with high accuracy, and the processing process can be simplified. For this reason, the molding time required for the molding process can be shortened and the molding cost can be reduced. In particular, in the case where the fitting groove is provided in the joint portion as described above and the fitting convex portion is provided in the joint end portion of each wall, the accuracy can be improved as compared with the method of molding from the plate material, In addition, the molding cost can be reduced. Here, as the extrusion process of the aluminum alloy, in the manufacturing method described above, a so-called solid shape such as a side arc wall, a vertical partition wall, an intermediate one-side wall, and an intermediate both-side wall can be formed at a relatively low processing cost. . On the other hand, a so-called hollow shape such as a side-closed arc wall has a higher processing cost than the solid shape. Therefore, it is only necessary to appropriately select each manufacturing method as described above in accordance with the use of the flat pressure vessel to be manufactured, together with the workability in the joining process.

また、上述した扁平圧力容器の製造方法にあって、成形工程が、スチールを圧延加工及び／又は引抜加工することにより成形するようにした製造方法が提案される。かかる製造方法により、スチール製の扁平圧力容器を製造する場合に、成形工程に要する時間を短縮できると共に、各部品の形状及び寸法の精度を適正なものとすることができる。したがって、成形費用を減少させることも可能である。ここで、圧延加工や引抜加工により成形するものとしては、上述した側部円弧壁、縦断隔壁、側部閉鎖円弧壁、中間片方壁、中間双方壁の扁平円筒胴部を形成する各部品である。尚、上述のように、皿状鏡部はプレス加工により成形することが望ましい。   Further, in the above-described flat pressure vessel manufacturing method, a manufacturing method is proposed in which the forming step forms the steel by rolling and / or drawing. With this manufacturing method, when manufacturing a flat pressure vessel made of steel, the time required for the forming process can be shortened, and the accuracy of the shape and dimensions of each component can be made appropriate. Therefore, it is possible to reduce the molding cost. Here, what is formed by rolling or drawing is each part that forms the above-described flat cylindrical body of the side circular arc wall, the vertical partition wall, the side closed circular arc wall, the intermediate one side wall, and the intermediate both walls. . As described above, the dish-shaped mirror part is desirably formed by press working.

上述したように、本発明の扁平圧力容器は、内部を、縦断隔壁により区画して長手方向に沿った複数の筒状主貯留域を幅方向へ並成してなる両端が開口する扁平円筒胴部と、該扁平円筒胴部の両端開口を覆って接合され、内部に各主貯留域を連通する連通領域を形成する皿状鏡部とで構成され、所定のガス又は液化ガスを容器内に充填する充填バルブ及び容器外に排出する排出バルブを少なくとも各一個備えてなるか、又は充填と排出とを行う入出バルブを少なくとも一個備えてなる構成としたものであるから、上述した従来の複合型圧力容器に比して、皿状鏡部の連通領域の貯留可能な容量が大きくなるため、容器全体の最大充填容量が増加し、略直方体状の搭載スペースに対する、燃料ガスの積載効率が向上する。また、従来の複合型圧力容器の各容器の鏡部総重量に比して、皿状鏡部の重量が軽くできるため、当該扁平圧力容器を軽量化することができる。さらに、充填バルブ及び排出バルブ又は入出バルブの配設数を少なくできるため、減少数に相当する重量だけ軽量化できる。   As described above, the flat pressure vessel according to the present invention has a flat cylindrical body whose ends are opened by dividing a plurality of cylindrical main storage areas along the longitudinal direction by dividing the inside by vertical partition walls. And a dish-shaped mirror part that covers and joins the opening at both ends of the flat cylindrical body part and forms a communication area that communicates with each main storage area inside, and a predetermined gas or liquefied gas is placed in the container. The above-described conventional composite type is provided with at least one filling valve and at least one discharge valve for discharging outside the container, or at least one input / output valve for filling and discharging. Compared to a pressure vessel, the capacity that can be stored in the communication region of the dish-shaped mirror is increased, so the maximum filling capacity of the entire vessel increases, and the loading efficiency of fuel gas in a substantially rectangular parallelepiped mounting space is improved. . Further, since the weight of the dish-shaped mirror portion can be reduced as compared with the total mirror portion weight of each container of the conventional composite pressure vessel, the flat pressure vessel can be reduced in weight. Further, since the number of filling valves and discharge valves or inlet / outlet valves can be reduced, the weight corresponding to the reduced number can be reduced.

ここで、扁平円筒胴部が、円弧の占める角度が１８０度以上の欠円状をなす断面円弧形状の長尺の側部円弧壁と、その欠円開口を覆う縦断隔壁とにより囲繞されて形成された、両側の筒状側部主貯留域を備えている構成とした場合にあっては、該扁平円筒胴部の扁平化に応じて形成される皿状鏡部の連通領域の容量が、上述した従来の複合型圧力容器に比して増加し、ガスの積載効率が向上する。また、この扁平円筒胴部は、幅方向（扁平方向）及び高さ方向に対して充分な剛性と強度とを発揮できる。そして、扁平形状であっても、高圧ガス保安法の容器保安規則に従うシリンダー型圧力容器の板厚計算結果と同等の板厚によって強度設計できる。而して、扁平圧力容器は、優れた強度及び剛性と軽量化との両者を満足できるものである。   Here, a flat cylindrical body is formed by being surrounded by a long side circular arc wall having a circular arc shape with a circular shape with an angle occupied by the circular arc of 180 degrees or more and a vertical partition wall covering the circular opening. In the case of the configuration including the cylindrical side main storage areas on both sides, the capacity of the communication area of the dish-shaped mirror part formed in accordance with the flattening of the flat cylindrical body part, Compared to the above-described conventional combined pressure vessel, the gas loading efficiency is improved. Moreover, this flat cylindrical trunk | drum can exhibit sufficient rigidity and intensity | strength with respect to the width direction (flat direction) and a height direction. And even if it is a flat shape, strength design can be carried out by the board thickness equivalent to the board thickness calculation result of the cylinder type pressure vessel according to the container security rule of the high-pressure gas safety method. Thus, the flat pressure vessel can satisfy both excellent strength and rigidity and weight reduction.

また、扁平円筒胴部が、相互に対峙する二面の縦断隔壁と、上下の円弧の占める角度が９０度以下である断面円弧形状の長尺の中間円弧壁とにより囲繞されて形成された筒状中間主貯留域と、該筒状中間主貯留域の両側の縦断隔壁と、円弧の占める角度が１８０度以上の欠円状をなす断面円弧形状の長尺の側部円弧壁とにより囲繞されて形成された、両側の筒状側部主貯留域とを備えている構成とした場合にあっては、扁平円筒胴部が中間円弧壁の分だけ幅方向にさらに扁平化され、該扁平化に従って皿状鏡部の連通領域の容量が増加する。また、この中間主貯留域が形成されていても、幅方向と高さ方向に対して充分な剛性と強度を発揮できると共に、軽量化も可能となる。   In addition, a cylinder formed by a flat cylindrical body surrounded by a vertical partition wall with two faces facing each other and a long intermediate arc wall having an arc shape with a cross-sectional arc shape in which the upper and lower arcs occupy 90 degrees or less Is surrounded by a cylindrical intermediate main storage area, vertical partition walls on both sides of the cylindrical intermediate main storage area, and a long side circular arc wall having an arcuate cross-section with an arc of 180 degrees or more. In this case, the flat cylindrical body is further flattened in the width direction by the amount of the intermediate arc wall, and the flattening is performed. Accordingly, the capacity of the communication area of the dish-shaped mirror portion increases. Further, even if this intermediate main storage area is formed, sufficient rigidity and strength can be exhibited in the width direction and the height direction, and the weight can be reduced.

ここで、扁平円筒胴部が、隣り合う二面が相互に対峙するように並立された複数の縦断隔壁の、各隣り合う二面の縦断隔壁毎に、上下一対の中間円弧壁と囲繞されて形成されたことにより、並列状に連成された複数の筒状中間主貯留域および、両側端の縦断隔壁と側部円弧壁とにより囲繞されて形成された両側の筒状側部主貯留域を備えている構成とした場合にあっては、搭載スペースの寸法に従って、適当数の筒状中間主貯留域が形成されてなるものとできるため、搭載スペースに応じた高いガス積載効率を発揮できる。また、かかる構成にあっても、扁平圧力容器の幅方向及び高さ方向に対して充分な強度及び剛性とを発揮できる。   Here, the flat cylindrical body is surrounded by a pair of upper and lower intermediate arc walls for each of the two adjacent vertical partition walls of a plurality of vertical partition walls arranged side by side so that two adjacent surfaces face each other. A plurality of cylindrical intermediate main storage areas that are coupled in parallel by being formed, and cylindrical side main storage areas on both sides that are formed by being surrounded by vertical partition walls and side arc walls on both ends. In the case of the configuration including the above, since an appropriate number of cylindrical intermediate main storage areas can be formed according to the size of the mounting space, high gas loading efficiency corresponding to the mounting space can be exhibited. . Even in such a configuration, sufficient strength and rigidity can be exhibited in the width direction and height direction of the flat pressure vessel.

また、上述した扁平円弧胴部が、側部円弧壁の断面円弧径と中間円弧壁の断面円弧径とを同径に形成してなるものである構成とした場合にあっては、扁平円弧胴部が、幅方向及び高さ方向の剛性と強度とのバランスに優れたものとなり、軽量化の効果も高い。   Further, in the case where the above-described flat arc body is formed by forming the cross-section arc diameter of the side arc wall and the cross-section arc diameter of the intermediate arc wall to be the same diameter, The portion has an excellent balance between rigidity and strength in the width direction and height direction, and the effect of weight reduction is also high.

このような扁平円筒胴部が、縦断隔壁の長手方向に沿った両辺端に、壁厚方向両外側に拡幅し、主壁部と拡幅部とを円弧凹面により連続する接合部を形成してなるものとした構成にあっては、扁平圧力容器に所定のガスを充填した場合に、該ガスの内圧によって該接合部に生じる応力集中を緩和でき、充填と排出との繰り返し応力に対する耐久性を向上できる。   Such a flat cylindrical body portion is widened to both outer sides in the wall thickness direction at both ends along the longitudinal direction of the longitudinal partition wall, and a joining portion is formed in which the main wall portion and the widened portion are continuous by an arc concave surface. In the configuration, when a flat pressure vessel is filled with a predetermined gas, the stress concentration generated in the joint can be relaxed by the internal pressure of the gas, and the durability against repeated stress of filling and discharging is improved. it can.

It has a cross section (see FIG. 3). The arc concave surface 41 a is formed with a concave radius r of t to 2 t with respect to the wall thickness t of the main wall portion 39. Further, the dish-shaped mirror portion 6 is formed in a dish shape having a curved surface having an arc diameter substantially equal to the cross-sectional arc of the side arc wall 4, and the mirror opening 37 is formed in the flat cylindrical body 2. It is formed in substantially the same shape as both-end openings 38 (see FIG. 4A). An integral air space is formed in the width direction inside the dish-shaped mirror portion 6.

上記した縦断隔壁５には、接合部７ａの高さ方向に対向する外表面３２ａに、長手方向に沿って嵌合凹溝３３，３３が並成されている（図３（イ）参照）。この嵌合凹溝３３，３３は、他辺の接合部７ａの外表面３２ａに形成された嵌合凹溝３３，３３と、上下方向でそれぞれ平行であり、かつ、壁厚方向で同位置となるように形成されている。また、側部円弧壁４の欠円開口端３５、３５には、前記接合部７ａの嵌合凹溝３３に嵌入する嵌合凸部３６、３６が形成されている（図３（イ）参照）。尚、この欠円開口端３５の嵌合凸部３６が形成されている部位が、本発明の接合端部である。   In the vertical partition wall 5 described above, fitting grooves 33 and 33 are juxtaposed along the longitudinal direction on the outer surface 32a facing the height direction of the joint portion 7a (see FIG. 3A). The fitting grooves 33 and 33 are parallel to the fitting grooves 33 and 33 formed on the outer surface 32a of the joint portion 7a on the other side in the vertical direction, and at the same position in the wall thickness direction. It is formed to become. Further, fitting convex portions 36 and 36 which are fitted into the fitting concave grooves 33 of the joint portion 7a are formed at the open ends 35 and 35 of the side circular arc wall 4 (see FIG. 3A). ). In addition, the site | part in which the fitting convex part 36 of this missing circle opening end 35 is formed is a junction end part of this invention.

成形工程としては、図示しない押出加工機に、いわゆるソリッド形状の側部円弧壁４、縦断隔壁５を夫々に成形するための所定のソリッドダイス（図示せず）を順次セットする。そして、図２（イ）のように、所定のアルミニウム合金を押出加工機により押出成形して、上記の側部円弧壁４を、扁平円筒胴部２の長さに比して数倍の長さに形成した前側部円弧壁３０と、同様に上記の縦断隔壁５を、扁平円筒胴部２の長さに比して数倍の長さに形成した前縦断隔壁３１とを夫々に成形する。尚、この前縦断隔壁３１には、上述した縦断隔壁５の接合部７ａ及び嵌合凹溝３３が連続して形成されている。同様に、前側部円弧壁３０には、上述した側部円弧壁４の嵌合凹部３６が連続して形成されている。   As a forming step, predetermined solid dies (not shown) for forming the so-called solid side arc wall 4 and the vertical partition wall 5 are sequentially set in an extruder (not shown). Then, as shown in FIG. 2A, a predetermined aluminum alloy is extruded by an extruder, and the side arc wall 4 is several times longer than the length of the flat cylindrical body 2. The front side circular arc wall 30 formed in the same manner as above and the front vertical partition wall 31 in which the above-described vertical partition wall 5 is formed several times longer than the length of the flat cylindrical body 2 are respectively formed. . The front vertical partition wall 31 is formed with the above-described joint 7a of the vertical partition wall 5 and the fitting concave groove 33 continuously. Similarly, the fitting recess 36 of the side arc wall 4 described above is continuously formed in the front arc wall 30.

その後、押出成形した前側部円弧壁３０と前縦断隔壁３１とを、図２（ロ）のように、所望の扁平円筒胴部２の長さに夫々に切断し、側部円弧壁４と縦断隔壁５とを得る。尚、この側部円弧壁４の長手方向の両開口には、外表面に皿状鏡部６を接合するための嵌合部を周成している（図示せず）。   Thereafter, the extruded front side arc wall 30 and the front longitudinal partition wall 31 are respectively cut to the length of the desired flat cylindrical body 2 as shown in FIG. A partition wall 5 is obtained. In addition, the fitting part for joining the plate-shaped mirror part 6 to the outer surface is formed in both opening of the longitudinal direction of this side part circular wall 4 (not shown).

また、アルミニウム合金の板材を、図示しないプレス加工により皿状鏡部６を成形する（図１（ロ）参照）。尚、この皿状鏡部６の鏡部開口の内面には、上記した側部円弧壁４の両開口の嵌合部と接合する嵌合周部が周成されている（図示せず）。このように、側部円弧壁４と縦断隔壁５、及び皿状鏡部６を成形する工程が、本発明にかかる成形工程である。   Moreover, the plate-shaped mirror part 6 is shape | molded by the press work which is not illustrated in the aluminum alloy board | plate material (refer FIG. 1 (B)). Note that a fitting peripheral portion (not shown) is formed on the inner surface of the mirror portion opening of the dish-shaped mirror portion 6 so as to join with the fitting portions of both openings of the side arc wall 4 described above. Thus, the process of shape | molding the side part circular arc wall 4, the vertical partition 5 and the plate-shaped mirror part 6 is a shaping | molding process concerning this invention.

次に、上記成形工程により成形した二つの側部円弧壁４と縦断隔壁５とを接合して扁平円筒胴部２を形成する。図３（イ）のように、縦断隔壁５の両接合部７ａ，７ａの、一側の上下の各嵌合凹溝３３，３３に、側部円弧壁４の嵌合凸部３６，３６を嵌入する。同様に、両接合部７ａ，７ａの他側の上下の嵌合凹溝３３，３３に、他の側部円弧壁４の嵌合凸部３６，３６を嵌入することにより、縦断隔壁５の両側に側部円弧壁４，４を組み付ける。そして、図３（ロ）のように、この嵌合凹溝３３に嵌合凸部３６を嵌入した外側から、長手方向に亘って溶接する（図示省略）。ここで、側部円弧壁４，４及び縦断隔壁５はアルミニウム合金製であることから、ミグ溶接を行った。このようにして、図４（イ）のように、両側の側部円弧壁４，４と縦断隔壁５とにより囲繞されて形成された筒状側部主貯留域３，３を並成した扁平円筒胴部２を得る。   Next, the flat cylindrical body 2 is formed by joining the two side circular arc walls 4 and the longitudinal partition walls 5 formed by the above forming step. As shown in FIG. 3 (a), the fitting convex portions 36, 36 of the side arcuate wall 4 are formed in the upper and lower fitting concave grooves 33, 33 on one side of the joint portions 7a, 7a of the vertical partition wall 5. Insert. Similarly, by fitting the fitting protrusions 36, 36 of the other side arc wall 4 into the upper and lower fitting grooves 33, 33 on the other side of the joints 7a, 7a, Assemble the side arcuate walls 4 and 4. Then, as shown in FIG. 3B, welding is performed in the longitudinal direction from the outside where the fitting convex portion 36 is inserted into the fitting concave groove 33 (not shown). Here, since the side arc walls 4 and 4 and the vertical partition wall 5 are made of an aluminum alloy, MIG welding was performed. In this way, as shown in FIG. 4 (a), the flat side wall in which the cylindrical side main storage areas 3 and 3 formed by being surrounded by the side arcuate walls 4 and 4 and the vertical partition walls 5 on both sides are arranged side by side. A cylindrical body 2 is obtained.

その後、図４（ロ）のように、この扁平円筒胴部２の両端開口３８，３８に、成形工程で成形した皿状鏡部６，６を接合する。すなわち、扁平円筒胴部２の両端開口３８，３８の周端と、皿状鏡部６，６の鏡部開口３７，３７の周端とを、ミグ溶接により接合することにより、両端開口３８，３８が皿状鏡部６，６で覆われる。このようにして図１（イ）に示す扁平圧力容器１が形成される。この扁平圧力容器１は、その内部が、二つの筒状側部主貯留域３，３を皿状鏡部６，６の内側の連通領域８で連通してなる一体的な内部形態となっている。
このように、側部円弧壁４と縦断隔壁５との溶接、及び皿状鏡部６を溶接する工程が、本発明にかかる接合工程である。 Thereafter, as shown in FIG. 4 (b), the dish-shaped mirror portions 6 and 6 formed in the forming step are joined to the both end openings 38 and 38 of the flat cylindrical body portion 2. That is, by opening the peripheral ends of the both end openings 38, 38 of the flat cylindrical body 2 and the peripheral ends of the mirror opening 37, 37 of the dish-like mirror parts 6, 6 by MIG welding, both end openings 38, 38 is covered with the dish-shaped mirror parts 6 and 6. In this way, the flat pressure vessel 1 shown in FIG. As for this flat pressure vessel 1, the inside becomes an integral internal form which connects the two cylindrical side part main storage areas 3 and 3 by the communication area 8 inside the dish-shaped mirror parts 6 and 6. FIG. Yes.
Thus, the process of welding the side circular arc wall 4 and the longitudinal partition wall 5 and welding the dish-shaped mirror part 6 are the joining process according to the present invention.

さらに、この接合工程で形成した扁平圧力容器１には、一方の皿状鏡部６の略中央に、内部に所定のガスを充填し、かつ、内部のガスを排出する入出バルブを取り付けるためのバルブ座１０が形成され、該バルブ座１０に入出バルブが配設される。また、図示しない、ガス充填量を確認する内容量計を取り付けるための内容量計座も形成され、所定の内容量計が配設される。これにより、所望の扁平圧力容器１が製造される（図１（イ））。   Further, the flat pressure vessel 1 formed in this joining step is provided with an inlet / outlet valve for filling a predetermined gas in the center of one dish-shaped mirror portion 6 and discharging the internal gas. A valve seat 10 is formed, and an inlet / outlet valve is disposed on the valve seat 10. Further, an internal volume meter seat for attaching an internal volume meter for checking the gas filling amount (not shown) is also formed, and a predetermined internal volume meter is provided. Thereby, the desired flat pressure vessel 1 is manufactured (FIG. 1 (A)).

このような製造方法にあっては、扁平圧力容器１を、比較的単純な形態とした側部円弧壁４、縦断隔壁５，皿状鏡部６の各構成部品毎に別々に成形し、これらを溶接して接合するようにした方法であり、部品点数と部品種類を少なくし、成形工程と接合工程とを簡素化したことにより、該扁平圧力容器１を容易かつ適正に製造することが可能である。また、成形工程にあって、扁平円筒胴部２に比して数倍の長さの前側部円弧壁３０及び前縦断隔壁３１を押出成形した後、切断して側部円弧壁４と縦断隔壁５とを成形するようにしたことにより、扁平圧力容器１を多量に製造する場合に、製造効率を一層向上させ得る。さらには、異なる長さの扁平圧力容器１を製造する場合にあっても、切断長さを変えることにより容易に対応することが可能である。一方、本製造方法では、成形工程でソリッド形状を押出成形するようにしていることから、押出加工に要する成形時間及び成形費用を比較的低めに抑えることができるという優れた利点もある。   In such a manufacturing method, the flat pressure vessel 1 is molded separately for each component of the side arc wall 4, the vertical partition wall 5, and the dish-shaped mirror part 6, which are in a relatively simple form. It is possible to manufacture the flat pressure vessel 1 easily and properly by reducing the number of parts and the types of parts and simplifying the molding process and the joining process. It is. Further, in the molding process, the front side arc wall 30 and the front longitudinal partition wall 31 which are several times longer than the flat cylindrical body 2 are extruded and then cut to cut the side arc wall 4 and the longitudinal partition wall. When the flat pressure vessel 1 is manufactured in a large amount, the manufacturing efficiency can be further improved. Furthermore, even when the flat pressure vessel 1 having a different length is manufactured, it is possible to easily cope with this by changing the cutting length. On the other hand, in this manufacturing method, since the solid shape is extruded in the molding process, there is also an excellent advantage that the molding time and molding cost required for the extrusion process can be kept relatively low.

Thus, the process of shape | molding the side part circular arc wall 4, the side part closed circular arc wall 9, and the plate-shaped mirror part 6 is a shaping | molding process concerning this invention.

次に、上記成形工程により成形した側部円弧壁４と側部閉鎖円弧壁９とを接合して扁平円筒胴部２を形成し、該扁平円筒胴部２に皿状鏡部６，６を接合する接合工程を行う。図５（ロ）のように、側部閉鎖円弧壁９の両接合部７ｂ，７ｂに形成された嵌合凹溝３３，３３に、側部円弧壁４の嵌合凸部３６，３６を嵌入し、側部閉鎖円弧壁９と側部円弧壁４とを組み付ける。そして、嵌合凹溝３３，３３に嵌合凸部３６，３６が嵌入した外側からそれぞれ、長手方向に亘ってミグ溶接を行う（図３（ロ）参照）。これにより、図４（イ）のように、側部閉鎖円弧壁９の縦断隔壁５と、側部円弧壁４により囲繞された筒状側部主貯留域３が形成され、上記した側部閉鎖円弧壁９に形成されている筒状側部主貯留域３と並列する扁平円筒胴部２を得る。   Next, the side circular arc wall 4 and the side closed circular arc wall 9 formed by the above forming step are joined to form the flat cylindrical body 2, and the dish-like mirror parts 6, 6 are attached to the flat cylindrical body 2.

次に、上記成形工程により成形した側部円弧壁４、三つの中間双方壁５０、側部閉鎖円弧壁９を接合して扁平円筒胴部２２を形成し、該該扁平円筒胴部２２に皿状鏡部２６，２６を接合する接合工程を行う。図１４（ロ）のように、側部閉鎖円弧壁９の両接合部７ｂ，７ｂに形成された嵌合凹溝３３，３３に、中間双方壁５０の上下の中間円弧壁１４，１４の嵌合凸部３６，３６を夫々に嵌入する。さらに、中間双方壁５０の両接合部７ｃ，７ｃに形成された嵌合凹溝３３，３３に、他の中間双方壁５０の嵌合凸部３６，３６を夫々に嵌入する。同様に、もう一つ他の中間双方壁５０の接合凸部３６，３６を順次嵌入する。そして、側端に在る中間双方壁５０の両接合部７ｃ，７ｃの両嵌合凹溝３３，３３に、側部円弧壁４の嵌合凸部３６，３６を嵌入する。これにより、側部円弧壁４、三つの中間双方壁５０、側部閉鎖円弧壁９を組み付ける。そして、各嵌合凹溝３３に嵌入凸部３６が嵌入する外側からそれぞれ、長手方向に亘ってミグ溶接する。このようにして、図１４（イ）に示す、三つの筒状中間主貯留域１３とその両側に筒状側部主貯留域３，３とを並成した扁平円筒胴部２２を得る。   Next, the side circular arc wall 4, the three intermediate both side walls 50, and the side closed circular arc wall 9 formed by the above forming step are joined to form the flat cylindrical body 22, and the flat cylindrical body 22 is provided with a dish. The joining process which joins the shape mirror parts 26 and 26 is performed. As shown in FIG. 14 (b), the upper and lower intermediate arc walls 14, 14 of the intermediate both walls 50 are fitted into the fitting concave grooves 33, 33 formed in both joint portions 7 b, 7 b of the side closed arc wall 9. The mating protrusions 36 and 36 are fitted into the respective parts. Further, the fitting convex portions 36 and 36 of the other intermediate both walls 50 are fitted into the fitting concave grooves 33 and 33 formed in the joint portions 7c and 7c of the intermediate both walls 50, respectively. Similarly, the joint projections 36 and 36 of the other intermediate both walls 50 are sequentially inserted. Then, the fitting convex portions 36 and 36 of the side arcuate wall 4 are fitted into the fitting concave grooves 33 and 33 of the joint portions 7c and 7c of the intermediate both walls 50 at the side ends. Thus, the side arc wall 4, the three middle both walls 50, and the side closing arc wall 9 are assembled. Then, MIG welding is performed across the longitudinal direction from the outside where the fitting protrusions 36 are fitted into the respective fitting grooves 33. In this way, a flat cylindrical body 22 is obtained in which three cylindrical intermediate main storage areas 13 and cylindrical side main storage areas 3 and 3 are arranged on both sides thereof as shown in FIG.

その後、図１４（イ）のように、この扁平円筒胴部２２の両端開口５８，５８の周端に、成形工程で成形した皿状鏡部２６，２６の鏡部開口３７，３７の周端をミグ溶接により接合する。これにより、図１３（イ）に示す、両側の筒状側部主貯留域３と三つの筒状中間主貯留域１３とを皿状鏡部２６，２６の内側の連通領域２８で連通してなる一体的な内部形態を有する扁平圧力容器２１を得る。ここで、この扁平圧力容器２１には、一方の皿状鏡部１６の略中央に入出バルブを取り付けるためのバルブ座１０が形成され、該バルブ座１０に入出バルブが配設される。また、図示しない、内容量計を取り付けるための内容量計座が形成され、所定の内容量計が配設される。このようにして、所望の扁平圧力容器２１が製造される。   Thereafter, as shown in FIG. 14 (a), peripheral ends of the mirror openings 37, 37 of the dish-shaped mirror portions 26, 26 formed in the forming process are formed at the peripheral ends of the both ends openings 58, 58 of the flat cylindrical body portion 22. Are joined by MIG welding. Thereby, the cylindrical side main storage area 3 on the both sides and the three cylindrical intermediate main storage areas 13 shown in FIG. 13 (a) are communicated with each other through the communication area 28 inside the dish-shaped mirror portions 26 and 26. A flat pressure vessel 21 having an integral internal form is obtained. Here, in the flat pressure vessel 21, a valve seat 10 for attaching an inlet / outlet valve is formed in the approximate center of one of the dish-shaped mirror portions 16, and the inlet / outlet valve is disposed in the valve seat 10. Further, an unillustrated internal capacity meter seat for attaching the internal capacity meter is formed, and a predetermined internal capacity meter is disposed. In this way, a desired flat pressure vessel 21 is manufactured.

このような製造方法では、前中間双方壁５１を少なくとも扁平円筒胴部２２の長さに比して三倍の長さに相当するように押出成形して、三つの中間双方壁５０を成形することにより、幅方向に長い（扁平率の高い）扁平圧力容器２１を容易かつ適正に製造できるようにしている。すなわち、本製造方法は、前中間双方壁５１の成形長さを長くすることにより製造できることから、同様に中間双方壁５０の連設数が異なる圧力容器も製造することが可能である。   In such a manufacturing method, the front intermediate wall 51 is extruded so as to correspond to a length at least three times as long as the length of the flat cylindrical body 22 to form the three intermediate walls 50. This makes it possible to easily and appropriately manufacture the flat pressure vessel 21 that is long in the width direction (high flatness). That is, since this manufacturing method can be manufactured by increasing the molding length of the front intermediate wall 51, it is also possible to manufacture pressure vessels in which the number of intermediate walls 50 are different.

本実施例５にあっては、溶接工程で、三つの中間双方壁５０を順次連接し、その両側に側部閉鎖円弧壁９、側部円弧壁４を夫々に接合することにより、三つの筒状中間主貯留域１３と両側の筒状側部主貯留域３とを並成してなる扁平圧力容器２１を製造する方法であって、中間双方壁５０を連接するようにした以外は、上述の実施例４とほぼ同様に製造するようにしている。そのため、同じ形態及び工程を表す記号は同じものを使用し、その説明は省略している。   In the fifth embodiment, in the welding process, the three intermediate side walls 50 are sequentially connected, and the side closed circular arc wall 9 and the side circular arc wall 4 are respectively joined to both sides thereof to thereby form three cylinders. This is a method of manufacturing a flat pressure vessel 21 formed by juxtaposing the cylindrical intermediate main storage area 13 and the cylindrical side main storage areas 3 on both sides, except that the intermediate both walls 50 are connected. The fourth embodiment is manufactured in substantially the same manner as in the fourth embodiment. For this reason, the same symbols are used for the same forms and processes, and descriptions thereof are omitted.

ここで、上述した実施例１〜実施例５の各製造方法により製造した扁平圧力容器１，１１，２１にあっては、それぞれの扁平円筒胴部２，１２，２２の筒状側部主貯留域３や筒状中間主貯留域１３が、各皿状鏡部６，１６，２６の連通領域８，１８，２８により一体な内部形態となるものである。これにより、各扁平圧力容器１，１１，２１が積載される搭載スペースに対して、それぞれ高いガス積載効率を発揮できる。   Here, in the flat pressure vessels 1, 11 and 21 manufactured by the manufacturing methods of the first to fifth embodiments described above, the cylindrical side main reservoirs of the respective flat cylindrical body portions 2, 12, and 22 are used. The area 3 and the cylindrical intermediate main storage area 13 form an integral internal form by the communication areas 8, 18, and 28 of the respective dish-shaped mirror portions 6, 16, and 26. Thereby, high gas loading efficiency can be exhibited with respect to the loading space in which the flat pressure vessels 1, 11 and 21 are loaded.

ここで、上述の実施例３で製造した扁平圧力容器１１（図１６（イ））について、上述した従来の、シリンダー型圧力容器７０（図１７（イ））及び複合型圧力容器７５（図１８（イ））に比して、ガス積載量を比較した。   Here, with respect to the flat pressure vessel 11 (FIG. 16 (a)) manufactured in the third embodiment, the conventional cylinder type pressure vessel 70 (FIG. 17 (a)) and the combined pressure vessel 75 (FIG. 18) are described. Compared to (i)), the gas loading capacity was compared.

本実施形態例にあっては、例えば、図１５（イ）のように、ＬＰＧを燃料ガスとするバス９０に、該ＬＰＧ用圧力容器が搭載されるようにした。搭載スペースＦは、バス９０の底部に略直方形状に設けられており、図１５（ロ）のように、長さＰ８００ｍｍ×高さＨ２００ｍｍ×奥行きＷ４００ｍｍとする。   In this embodiment, for example, as shown in FIG. 15A, the LPG pressure vessel is mounted on a bus 90 using LPG as fuel gas. The mounting space F is provided in a substantially rectangular shape at the bottom of the bus 90, and has a length P800 mm × height H200 mm × depth W400 mm as shown in FIG.

そして、かかる搭載スペースＦに搭載される、本発明にかかる扁平圧力容器１１として、側部円弧壁４及び中間円弧壁１４の円弧半径を約１００ｍｍ（すなわち、高さが２００ｍｍ）とし、、容器幅を約４００ｍｍとし、容器長を約７００ｍｍとする（図１６（イ））。一方、同じ搭載スペースＦに搭載される、従来のシリンダー型圧力容器７０を、胴部外径約２００ｍｍとし、容器長を約７００ｍｍとする（図１７（イ））。同様に、この搭載スペースＦに搭載される、従来の複合型圧力容器７５を、各胴部の高さを２００ｍｍとし、容器幅を約４００ｍｍとし、容器長は約７００ｍｍとする（図１８（イ））。   And as the flat pressure vessel 11 concerning this invention mounted in this mounting space F, the circular arc radius of the side circular arc wall 4 and the intermediate | middle circular arc wall 14 shall be about 100 mm (namely, height is 200 mm), and container width Is about 400 mm, and the container length is about 700 mm (FIG. 16A). On the other hand, a conventional cylinder type pressure vessel 70 mounted in the same mounting space F has a barrel outer diameter of about 200 mm and a vessel length of about 700 mm (FIG. 17A). Similarly, a conventional composite pressure vessel 75 mounted in the mounting space F has a body height of 200 mm, a container width of about 400 mm, and a container length of about 700 mm (see FIG. )).

このような搭載スペースＦに搭載される、本発明の扁平圧力容器１１のガス充填量は、約４７リットルとなる。一方、従来のシリンダー型圧力容器７０にあっては、ガス充填量が約２０リットルであり、搭載スペースＦに二本搭載可能であることから、総ガス充填量は約４０リットルとなる。また、従来の複合型圧力容器７５にあっては、ガス充填量が約４５リットルとなる。したがって、本発明にかかる扁平圧力容器１１は、最も多量のガス又は液化ガスを充填でき、直方体状の搭載スペースＦのガス積載効率が最も高いものである。
これは、搭載スペースＦに扁平圧力容器１１を搭載した場合に（図１５（ロ））、図１６（ロ）に示す縦断面にあって、図１７（ロ）に示すシリンダー型圧力容器７０を二本搭載した場合に比して、デッドスペースＸを減少できる。さらに、図１６（ハ）に示す横断面にあっても、鏡部のデッドスペースＸが、図１７（ハ）に示す圧力容器７０に比して減少している。また、同様に、図１７（ハ）に示す複合型圧力容器７５を搭載した場合に比して、鏡部のデッドスペースＸが減少している。このように、本発明にかかる扁平圧力容器１１は、直方体状の搭載スペースＦに対して、最もデッドスペースＸが少ないことから、ガス又は液化ガスを充填する内容積が最も大きくなり、多量のガス又は液化ガスを充填することが可能である。而して、搭載スペースＦに対するガス積載効率が最も高くなる。 The gas filling amount of the flat pressure vessel 11 of the present invention mounted in such a mounting space F is about 47 liters. On the other hand, in the conventional cylinder type pressure vessel 70, the gas filling amount is about 20 liters, and two can be mounted in the mounting space F, so the total gas filling amount is about 40 liters. Further, in the conventional composite pressure vessel 75, the gas filling amount is about 45 liters. Therefore, the flat pressure vessel 11 according to the present invention can be filled with the largest amount of gas or liquefied gas, and has the highest gas loading efficiency in the rectangular parallelepiped mounting space F.
When the flat pressure vessel 11 is mounted in the mounting space F (FIG. 15 (b)), the cylinder-shaped pressure vessel 70 shown in FIG. The dead space X can be reduced as compared with the case where two are installed. Further, even in the cross section shown in FIG. 16C, the dead space X of the mirror portion is reduced as compared with the pressure vessel 70 shown in FIG. Similarly, the dead space X of the mirror portion is reduced as compared with the case where the composite pressure vessel 75 shown in FIG. Thus, since the flat pressure vessel 11 according to the present invention has the smallest dead space X with respect to the rectangular parallelepiped mounting space F, the internal volume filled with gas or liquefied gas becomes the largest, and a large amount of gas Or it can be filled with liquefied gas. Thus, the gas loading efficiency for the mounting space F is the highest.

ここで、本発明にかかる扁平圧力容器１１は、上述したように、高圧ガス保安法の容器保安規則に従う板厚設計結果から得られるシリンダー型圧力容器７０の板厚と、同等の板厚として強度設計することが可能である。したがって、同じアルミニウム合金で成形した場合に、胴部、鏡部をそれぞれシリンダー型圧力容器７０と同じ板厚により製造することができる。このように同じ板厚により製造された、扁平圧力容器１１と、シリンダー型圧力容器７０とを、上述した搭載スペースＦに搭載するようにした場合、本発明にかかる扁平圧力容器１１の方が、二本搭載されるシリンダー型圧力容器７０に比して軽量となる。同様に、上述した複合型圧力容器７５を同じ板厚で製造した場合にあっても、本発明の扁平圧力容器１１の方が軽量となる。また、従来のシリンダー型圧力容器７０には各一個、合計二個の入出バルブを必要とし、複合型圧力容器７５には三個の入出バルブを必要とすることから、一個の入出バルブが配設された扁平圧力容器１１は、入出バルブの減少分に相当しても軽量化されている。尚、上述した扁平圧力容器１及び扁平圧力容器２１にあっても、扁平圧力容器１１と同様に、シリンダー型圧力容器７０と同等の板厚により強度設計することが可能である。   Here, as described above, the flat pressure vessel 11 according to the present invention has a strength equivalent to the plate thickness of the cylinder-type pressure vessel 70 obtained from the plate thickness design result according to the vessel safety rules of the High Pressure Gas Safety Act. It is possible to design. Therefore, when formed with the same aluminum alloy, the body part and the mirror part can be manufactured with the same plate thickness as the cylinder type pressure vessel 70. When the flat pressure vessel 11 and the cylinder-type pressure vessel 70 manufactured with the same plate thickness are mounted in the mounting space F described above, the flat pressure vessel 11 according to the present invention is It is lighter than the two cylinder-type pressure vessels 70 mounted. Similarly, even when the composite pressure vessel 75 described above is manufactured with the same plate thickness, the flat pressure vessel 11 of the present invention is lighter. In addition, since the conventional cylinder type pressure vessel 70 requires one each, a total of two inlet / outlet valves, and the composite type pressure vessel 75 requires three inlet / outlet valves, one inlet / outlet valve is provided. The flattened pressure vessel 11 is lightened even if it corresponds to the reduced amount of the inlet / outlet valve. Even in the flat pressure vessel 1 and the flat pressure vessel 21 described above, it is possible to design the strength with a plate thickness equivalent to that of the cylinder type pressure vessel 70, similarly to the flat pressure vessel 11.

一方、上述した本発明の扁平圧力容器１，１１，２１にあっては、各扁平円筒胴部２，１２，２２が、側部円弧壁４や中間円弧壁１４により形成されていること、及び該胴部内に縦断隔壁５がそれぞれ形成されていることから、この扁平化した胴部の幅方向と高さ方向に対して優れた強度と剛性とを発揮できる。したがって、皿状鏡部６，１６，２６の内部に連通領域８，１８，２８が形成されていても、充分な強さを有するものとなる。さらには、各扁平圧力容器１，１１，２１は、縦断隔壁５の縦断隔壁５の両接合部７ａ，７ｂ，７ｃにそれぞれ円弧凹面４１ａ，４１ｂ，４１ｃを夫々に形成したことにより、当該圧力容器に所定のガスを充填した場合にかかる内圧により作用する応力集中を緩和することができる。而して、本発明の扁平圧力容器１，１１，２１は、外部から作用する外圧負荷やガス充填／排出による繰り返し内圧負荷等に対して、充分な強度と耐久性とを発揮することができる。   On the other hand, in the flat pressure vessels 1, 11 and 21 of the present invention described above, the flat cylindrical barrels 2, 12, and 22 are formed by the side circular arc wall 4 and the intermediate circular arc wall 14, and Since the vertical partition walls 5 are respectively formed in the body portion, excellent strength and rigidity can be exhibited in the width direction and the height direction of the flattened body portion. Therefore, even if the communication regions 8, 18, and 28 are formed inside the dish-shaped mirror portions 6, 16, and 26, the strength is sufficient. Furthermore, each flat pressure vessel 1, 11, 21 is formed by forming arcuate concave surfaces 41 a, 41 b, 41 c at the joints 7 a, 7 b, 7 c of the longitudinal partition 5 of the longitudinal partition 5, respectively. When the gas is filled with a predetermined gas, stress concentration acting on the internal pressure can be reduced. Thus, the flat pressure vessels 1, 11 and 21 of the present invention can exhibit sufficient strength and durability against external pressure loads acting from the outside or repeated internal pressure loads due to gas filling / discharging. .

上述した実施例１〜実施例５の製造方法にあって、接合工程では各嵌合凹溝３３に嵌合凸部３６を嵌入して胴部形状に組み付けた後、溶接するようにした方法であるが、その他の方法として、それぞれ、嵌入する毎に、溶接するようにしても良い。また、この製造方法にあっては、ガスを充填及び排出できる入出バルブを配設した構成であるが、ガス充填バルブとガス排出バルブとを別々に設けるようにしても良い。また、入出バルブ（又はガス充填バルブや排出バルブ）、内容量計は、成形工程後に所定部品に配設した後、接合工程により接合されて圧力容器が形成されるようにすることもできる。   In the manufacturing method of the first to fifth embodiments described above, in the joining process, the fitting convex portions 36 are inserted into the respective fitting concave grooves 33 and assembled into the body shape, and then welded. However, as another method, it is possible to weld each time it is inserted. In this manufacturing method, an inlet / outlet valve capable of filling and discharging gas is provided, but a gas filling valve and a gas discharge valve may be provided separately. Further, the inlet / outlet valve (or gas filling valve or exhaust valve) and the internal volume meter may be arranged in a predetermined part after the molding process, and then joined by the joining process to form a pressure vessel.

また、上述した実施例１〜実施例５にあっては、アルミニウム合金を押出成形することにより、扁平円筒胴部２，１２，２２を形成する各部品を成形し、アルミニウム合金製の扁平圧力容器１，１１，２１を製造した構成であるが、その他として、スチールを圧延加工又は引抜加工することにより、扁平円筒胴部を形成する各部品を成形し、アルミニウム合金製を同形状の、各スチール製扁平圧力容器を製造することもできる。   Further, in the above-described first to fifth embodiments, the aluminum alloy is extruded to form the respective parts forming the flat cylindrical body portions 2, 12, and 22, and the flat pressure vessel made of aluminum alloy is formed. 1, 11 and 21 are manufactured, but in addition, each part that forms a flat cylindrical body is formed by rolling or drawing steel, and each steel having the same shape made of aluminum alloy A flat pressure vessel can be manufactured.

本発明の扁平圧力容器としては、上述したような自動車のＬＰＧやＣＮＧの燃料タンクだけでなく、消防士等の空気用ボンベや酸素ボンベ等に適用することも可能である。   The flat pressure vessel of the present invention can be applied not only to the above-described automobile LPG and CNG fuel tanks but also to air cylinders, oxygen cylinders and the like of firefighters.
