Description

本発明は、特に上水用の開閉弁として用いるボール弁を壁面などに取り付けるための固定構造に関するものである。   The present invention relates to a fixing structure for attaching a ball valve used as an on-off valve for water supply to a wall surface or the like.

家庭内配水を配管し、吐水機器を設置する際に、開閉弁としてボール弁を用いることは周知である。又、最近の家庭内配管には、軟質管やアルミニウムパイプの三層管が用いられるのが主流であり、管の先端部にボール弁が取り付けられる。この場合、配管を完了したボール弁の下流側にはさらに吐水機器が取付けられるが、配管に比べて比較的重量があるボール弁であるから、振動などに対処するためにボール弁自体を何らかの手段で固定することが好ましい。   It is well known that a ball valve is used as an open / close valve when piping a domestic water supply and installing a water discharge device. In recent domestic piping, a three-layer pipe such as a soft pipe or an aluminum pipe is mainly used, and a ball valve is attached to the tip of the pipe. In this case, a water discharge device is further attached to the downstream side of the ball valve that has completed the piping. However, since the ball valve has a relatively heavy weight compared to the piping, the ball valve itself is used as a means for dealing with vibrations. It is preferable to fix with.

この場合、例えばボール弁本体を壁面などに固定しようとすると、配管の設定誤差を吸収するための構成が必要となる。このような構成の一例としては、伸縮ジョイント、あるいは伸縮管継手が公知である。   In this case, for example, when the ball valve main body is to be fixed to a wall surface or the like, a configuration for absorbing piping setting errors is required. As an example of such a configuration, an expansion joint or an expansion pipe joint is known.

特開平０９−２５７１７８号公報JP 09-257178 A

先行技術として示した伸縮管継手は、一定長さの配管誤差を管継手の伸縮によって吸収することができるので、便利である。しかしながら、伸縮管継手の構造は、固定管と伸縮管の二重構造であるから、コストが高くなる他、部品点数が多くなり、さらには伸縮管が存在するために大径化するという問題がある。特に配管スペースに制約がある場所に取り付ける場合には、装置の大型化は重要な問題となる。   The expansion pipe joint shown as the prior art is convenient because a pipe error of a certain length can be absorbed by the expansion and contraction of the pipe joint. However, since the structure of the expansion pipe joint is a double structure of the fixed pipe and the expansion pipe, there is a problem that the cost is increased, the number of parts is increased, and the diameter of the expansion pipe is increased due to the presence of the expansion pipe. is there. In particular, when mounting in a place where the piping space is restricted, the enlargement of the apparatus becomes an important problem.

一方、伸縮継手を用いることなく継手から特定の装置に配管を接続する構造としては、図６に示す例がある。ここで、６０は継手、６１は配管を接続する相手としての装置であり、その間をフレキシブル管６２で接続している。フレキシブル管６２は継手６０と装置６１の微細な距離の誤差を吸収するので、便利である。しかしながら、フレキシブル管６２を装置６１の雄ネジ６３に螺合する場合に、作業スペースに十分な余裕があれば問題はないが、仮に継手６０が露出している浴室点検口からしか作業を行うことができないとすると、図のように障害物を回避しながらフレキシブル管６２を配管しなければならない場合には、作業が極めて困難になるという問題がある。また、図示したような作業スペースの限られた状況では、フレキシブル管６２を回して装置側の雄ネジ６３に螺合することは作業性が悪く、接続ミスの原因となりかねない。   On the other hand, there is an example shown in FIG. 6 as a structure for connecting piping from a joint to a specific device without using an expansion joint. Here, 60 is a joint, 61 is a device as a counterpart to which piping is connected, and a flexible pipe 62 connects between them. The flexible tube 62 is convenient because it absorbs a minute distance error between the joint 60 and the device 61. However, when the flexible tube 62 is screwed into the male screw 63 of the device 61, there is no problem if there is sufficient work space, but the work should be performed only from the bathroom inspection port where the joint 60 is exposed. If the flexible pipe 62 must be installed while avoiding obstacles as shown in the figure, there is a problem that the operation becomes extremely difficult. Further, in the situation where the working space is limited as shown in the figure, turning the flexible tube 62 and screwing it into the male screw 63 on the apparatus side is inferior in workability and may cause a connection error.

そこで、本発明では、これらの課題を解決しようとしたもので、比較的簡単な構造によって、スペースに制約がある場所にも容易に固定することができる微調整を可能としたボール弁の固定構造を開示することを目的とする。   Therefore, the present invention is intended to solve these problems, and a ball valve fixing structure capable of fine adjustment that can be easily fixed in a place where space is limited by a relatively simple structure. It aims to disclose.

本発明のボール弁の固定構造は、上記課題を解決するために、一次側流路と、二次側流路と、これら一次側流路と二次側流路の間に位置するボールバルブを備えたボール弁を基本的な構造としている。そして、二次側流路は外径を等径とした一定長の円筒部を備えており、この円筒部の外周には、ブッシュを介して壁面等に固定するための固定板を設けるという手段を採用することとした。一次側流路と二次側流路の間にボールバルブを有する構造は公知である。本発明の特徴的な構造は、二次側流路の構成として、外径を等径とするパイプ状の円筒部を備えることである。円筒部は、一定長が外径を等径としているので、同じ内径を有する部材を摺動させることができる。ここで、同じ内径とは、力が加わらない状態で同じ内径であっても、弾性的に拡径した結果として同じ内径になる構成であってもよい。ブッシュは固定板を支持する基礎となるもので、これを円筒部に摺動させて位置決めすることにより、固定板の位置決めが行われる。円筒部の先端側を給水器具の内部配管と接続するように構成した場合は、ボール弁が何らかの原因で壁面から離れる方向に引っ張られても、ボール弁の脱落を抑制する。また、ボール弁の先端に、環状の凸条を設ける手段を採用した場合には、万が一、給水器具の内部配管との接続部に不良が発生した場合であっても、凸条がブッシュを規制し、ボール弁の脱落および給水装置外部への水漏れを抑制する。   In order to solve the above problems, the ball valve fixing structure of the present invention includes a primary side flow path, a secondary side flow path, and a ball valve positioned between the primary side flow path and the secondary side flow path. The provided ball valve has a basic structure. And the secondary side flow path is provided with a fixed-length cylindrical portion having an equal outer diameter, and a fixing plate for fixing to a wall surface or the like via a bush on the outer periphery of the cylindrical portion. It was decided to adopt. A structure having a ball valve between the primary side channel and the secondary side channel is known. A characteristic structure of the present invention is that a pipe-shaped cylindrical portion having an equal outer diameter is provided as the configuration of the secondary flow path. Since the cylindrical portion has a constant length and an equal outer diameter, a member having the same inner diameter can be slid. Here, the same inner diameter may be the same inner diameter in a state where no force is applied, or the same inner diameter as a result of elastic expansion. The bush serves as a base for supporting the fixed plate, and the fixed plate is positioned by sliding the bush on the cylindrical portion for positioning. In the case where the tip end side of the cylindrical portion is connected to the internal pipe of the water supply device, the ball valve is prevented from dropping even if the ball valve is pulled away from the wall surface for some reason. In addition, when a means for providing an annular ridge at the tip of the ball valve is used, the ridge regulates the bush even if a failure occurs in the connection with the internal piping of the water supply device. In addition, the ball valve is prevented from dropping and water leakage to the outside of the water supply device.

また、ブッシュのより具体的な構成として、その内径がボール弁の円筒部の外形より小さく、拡径状態で前記円筒部に摺動可能に取り付けられた弾性材を採用することとした。素材が弾性材であるから、ブッシュは円筒部に対して緊密に位置決めされ、少々の外力では横滑りすることはない。なお、ブッシュが弾性材であることにより、壁面からボール弁への振動、あるいは逆にボール弁から壁面への振動を吸収し、機器を保護すると同時に、異音の発生を抑制する。 Further, as a more specific configuration of the bush, an elastic material having an inner diameter smaller than the outer shape of the cylindrical portion of the ball valve and slidably attached to the cylindrical portion in an expanded state is employed. Since the material is an elastic material, the bush is closely positioned with respect to the cylindrical portion, and does not skid with a little external force. Since the bush is made of an elastic material, vibration from the wall surface to the ball valve, or conversely, vibration from the ball valve to the wall surface is absorbed to protect the device and to suppress the generation of abnormal noise.

さらにまた、ブッシュの外周には環状溝を設け、この環状溝に対して固定板の中心部に設けられた円形孔の内周縁を嵌合させるという手段を用いた。この手段では、予め固定板の内周縁に沿ってブッシュの環状溝を嵌合しておき、その組み合わせ状態でこれらをボール弁の円筒部に挿通することにより、容易に組立てができる。固定板に設けられたビス孔によって、壁面等へボール弁を固定する。二次側流路の先端側に、さらに給水器具の内部配管と接続できる接続口を設ける手段では、例えば給水器具をクイックファスナーなどで簡単に接続することができ、作業性が向上する。また、固定板が円筒部を摺動させて位置決めする構造であるため、給水器具の内部配管位置が給水器具により異なる場合であっても、二次側流路のパイプ状円筒部の一定長の範囲内であれば、位置調整が可能である。   Furthermore, an annular groove is provided on the outer periphery of the bush, and means for fitting the inner peripheral edge of a circular hole provided in the central portion of the fixing plate to the annular groove is used. In this means, the annular groove of the bush is fitted in advance along the inner peripheral edge of the fixed plate, and these can be assembled easily by inserting them into the cylindrical portion of the ball valve in the combined state. The ball valve is fixed to a wall surface or the like by a screw hole provided in the fixing plate. By means of providing a connection port that can be connected to the internal pipe of the water supply device at the distal end side of the secondary channel, for example, the water supply device can be easily connected with a quick fastener or the like, and workability is improved. In addition, since the fixed plate has a structure in which the cylindrical portion is slid and positioned, even if the internal piping position of the water supply device differs depending on the water supply device, the fixed length of the pipe-shaped cylindrical portion of the secondary channel is If it is within the range, position adjustment is possible.

本発明は、上述した構成を採用したので、ボール弁装置を壁面などに取り付ける場合でも、伸縮管継手のような複雑な機器を用いることなく取付位置の微調整が可能な構造を提供することができる。また、ブッシュとして弾性材を用いる場合には、ボール弁と壁面などとの間の振動を互いに遮断することができ、機器を保護することができると同時に、異音の発生を抑制することができる。   Since the present invention adopts the above-described configuration, it is possible to provide a structure capable of finely adjusting the mounting position without using a complicated device such as an expansion joint even when the ball valve device is mounted on a wall surface or the like. it can. In addition, when an elastic material is used as the bush, vibrations between the ball valve and the wall surface can be isolated from each other, and the device can be protected and at the same time the generation of abnormal noise can be suppressed. .

以下、本発明の好ましい実施の形態を添付した図面に従って説明する。図１は本実施形態が予定する取り付け状態を示す概略図、図２は本発明の固定構造の一実施形態を示す平面図、図３は同断面図、図４は側面図である。図中、１はボール弁本体で、ハンドル２の軸と直結したボールバルブ３と、ボールバルブ３を挟んで一次側流路４、二次側流路５が設けられている。６は必要に応じて設けられる逆止弁である。一次側流路４の外側にはキャップ７が設けられ、その内部にはチャックリング８、ロックリング９、スプリング１０などが組み込まれているが、実施形態の構成は樹脂管や三層管（図示せず）を強く挿入するだけで管が固定される、いわゆるワンタッチジョイントを示したものである。ただし、本発明はこれらのジョイントの構成は必須のものではなく、ボール弁１の一次側流路４に対して公知の手段で管を接続することができるものであれば、その構成を限定するものではない。   Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a schematic view showing a mounting state planned by the present embodiment, FIG. 2 is a plan view showing an embodiment of a fixing structure of the present invention, FIG. 3 is a sectional view thereof, and FIG. In the figure, reference numeral 1 denotes a ball valve body, which is provided with a ball valve 3 directly connected to the shaft of the handle 2, and a primary channel 4 and a secondary channel 5 sandwiching the ball valve 3. 6 is a check valve provided as needed. A cap 7 is provided on the outer side of the primary flow path 4, and a chuck ring 8, a lock ring 9, a spring 10, and the like are incorporated therein, but the configuration of the embodiment is a resin tube or a three-layer tube (see FIG. This shows a so-called one-touch joint in which the tube is fixed by simply inserting it (not shown). However, in the present invention, the configuration of these joints is not essential, and the configuration is limited as long as a pipe can be connected to the primary flow path 4 of the ball valve 1 by a known means. It is not a thing.

次に、本発明の重要な構成を説明すると、二次側流路５は一定長を外径を等径とする円筒１１によって構成され、円筒１１の内部流路が二次側流路として機能する。１２は二次側流路５の先端部に設けられた吐水口であり、必要に応じて吐水機器を接続する。例えば、図１のように本実施形態のボール弁を風呂場の天井面Ａの裏側のミスト発生装置Ｂに接続する場合には、吐水口１２の先にはミスト発生部への給水配管（図示せず）がクイックファスナーにより接続される。１３は、実施形態のボール弁を住宅の壁面などに固定するための固定板であり、図３に示すように周囲４箇所にビス孔１４が設けられている。固定板１３の材質は特に限定するものではないが、酸やアルカリによって腐食しないようにステンレス板を用いることがある。１５は円環状の弾性材からなるブッシュであり、内径を円筒１１の外径よりやや小さく設定し、円筒１１に押し込むことによって円筒１１の一定長の範囲で位置決めされる。１６はブッシュ１５の外周に設けられた環状溝であり、固定板１３の中央部に設けられた円形孔１７の内周縁が環状溝１６に嵌合することによって、双方が物理的に一体として機能する。１８はミスト発生装置Ｂの筐体の一壁面、１９はビス孔１４を貫通するビスである。   Next, an important configuration of the present invention will be described. The secondary side flow path 5 is constituted by a cylinder 11 having a constant length and an equal outer diameter, and the internal flow path of the cylinder 11 functions as a secondary side flow path. To do. Reference numeral 12 denotes a water discharge port provided at the tip of the secondary channel 5, and connects a water discharge device as necessary. For example, when the ball valve of the present embodiment is connected to the mist generating device B on the back side of the ceiling surface A of the bathroom as shown in FIG. 1, the water supply pipe to the mist generating unit (see FIG. (Not shown) are connected by a quick fastener. Reference numeral 13 denotes a fixing plate for fixing the ball valve of the embodiment to a wall surface of a house, etc., and screw holes 14 are provided at four locations around as shown in FIG. The material of the fixing plate 13 is not particularly limited, but a stainless plate may be used so as not to be corroded by acid or alkali. A bush 15 made of an annular elastic material is set within a certain length range of the cylinder 11 by setting the inner diameter slightly smaller than the outer diameter of the cylinder 11 and pushing it into the cylinder 11. Reference numeral 16 denotes an annular groove provided on the outer periphery of the bush 15, and the inner peripheral edge of the circular hole 17 provided in the central portion of the fixed plate 13 is fitted into the annular groove 16, so that both function as a physical unit. To do. Reference numeral 18 denotes one wall surface of the casing of the mist generator B, and 19 denotes a screw that penetrates the screw hole 14.

ブッシュ１５は、本実施形態では例えば合成ゴムのような弾性材として説明したが、弾性材のブッシュを用いた場合には、壁面の振動はブッシュによって吸収されてボール弁１には伝達されないので、機器の保護が可能となる。又、ボール弁１や軟質管などが発生する振動もブッシュによって吸収されるので、壁面には伝達されることがなく、異音の原因を低減させることが可能である。ただし、ブッシュ１５に求められる第一の機能は円筒１１に対して固定板１３の位置を決める際に微調整が可能であることであり、これを達成することができるのであれば、弾性材に限定されない。例えば硬質の合成樹脂の半割り体を一対用いることも本発明が想定する範囲である。   In the present embodiment, the bush 15 has been described as an elastic material such as synthetic rubber. However, when an elastic material bush is used, the vibration of the wall surface is absorbed by the bush and is not transmitted to the ball valve 1. Equipment can be protected. In addition, vibration generated by the ball valve 1 and the soft pipe is also absorbed by the bush, so that it is not transmitted to the wall surface, and the cause of abnormal noise can be reduced. However, the first function required for the bush 15 is that fine adjustment is possible when determining the position of the fixed plate 13 with respect to the cylinder 11, and if this can be achieved, the elastic material can be It is not limited. For example, the use of a pair of hard synthetic resin halves is within the scope of the present invention.

図５は、円筒１１の変形例であって、円筒１１の先端側に僅かな高さの環状の凸条２０を設けたものである。そして、ブッシュ１５は設置時には凸条２０を乗り越えてボール弁３側に設備される。このようにすれば、何らかの原因でボール弁本体１が壁面１８から離れる方向に引っ張られたときでも、凸条２０がこれを規制し、完全な脱落を防止することができる。   FIG. 5 shows a modification of the cylinder 11 in which an annular ridge 20 having a slight height is provided on the distal end side of the cylinder 11. The bush 15 is installed on the ball valve 3 side over the ridge 20 at the time of installation. In this way, even when the ball valve main body 1 is pulled in a direction away from the wall surface 18 for some reason, the ridge 20 can regulate this and prevent complete dropout.
