Description

この発明は、特に高層ビルなどのような多層階に高圧流体の送給が可能な防振用ベローズ管継手に関する。    The present invention relates to a vibration-proof bellows pipe joint capable of supplying a high-pressure fluid to a multilayer floor such as a high-rise building.

従来、ビル建築やブラント配管などの際には防振用の継手が使用されている。このような防振用の継手は、下層側から上層側へと高圧流体の送給を行うためにボンプが設置されており、機械的振動が配管を伝播し騒音を発生するのを防ぐため、特にポンプの吸入側と吐出側に防振用継手が必要とされている。    Conventionally, anti-vibration joints are used for building construction and blunt piping. In such a vibration-proof joint, a pump is installed to supply high-pressure fluid from the lower layer side to the upper layer side, so that mechanical vibrations propagate through the piping and generate noise, In particular, anti-vibration joints are required on the suction side and discharge side of the pump.

耐圧性と振動吸収性に優れる防振用の継手として、図３に示すようなものが知られている（特許文献１）。すなわち、この防振用の継手１は、山部２ａと谷部２ｂとを交互に連設した薄板を重ねた複数眉のベローズ管２よりなるもので、単眉構造のベローズ管に比べ大幅に耐圧性の向上が図られており、ベローズ管２の両端側にはそれぞれ他部材と接続される左右一対のフランジ部（突出部）３，３が固着され、管体軸方向の振動を防止するような構造とされている。    As an anti-vibration joint having excellent pressure resistance and vibration absorption, the one shown in FIG. 3 is known (Patent Document 1). In other words, the vibration-proof joint 1 is composed of a plurality of eyebrows bellows tubes 2 in which thin plates with alternately connected peaks 2a and valleys 2b are stacked, which is significantly larger than a bellows tube having a single eyebrow structure. The pressure resistance is improved, and a pair of left and right flange portions (projections) 3 and 3 connected to other members are fixed to both ends of the bellows tube 2 to prevent vibration in the axial direction of the tube body. It has a structure like this.

左右一対のフランジ部３，３には、それぞれ貫通孔４，４が穿設されると共に、貫通孔４，４同士の間には捧状体５が挿通されて架け渡されている。
棒状体５の両端部には、それぞれ皿バネ５ａ，５ａと合成ゴムや合成樹脂等からなる緩衝材５ｂ，５ｂが挿通され、平ワッシヤ６ａ，６ａとナット６ｂ，６ｂを介してネジ部６，６と螺合されている。なお、７，７は貫通孔４，４の内方に穿設された配管接続用の取付孔である。The pair of left and right flange portions 3, 3 are provided with through holes 4, 4, respectively, and a dedicated body 5 is inserted between the through holes 4, 4.
Disc springs 5a, 5a and cushioning materials 5b, 5b made of synthetic rubber, synthetic resin or the like are inserted into both ends of the rod-like body 5, and screw parts 6, 6a, 6a and nuts 6b, 6b are inserted through the flat washers 6a, 6a. 6. In addition, 7 and 7 are attachment holes for pipe connection drilled inside the through holes 4 and 4.

特許文献１（特開１０−２５２９６３号公報）Patent Document 1 (Japanese Patent Laid-Open No. 10-252963)

このような防振用の継手１は、左右一対のフランジ部３，３が棒状体５により連結された方式であり、これによって継手１の管内に高圧流体が流通したとしても軸方向の伸長等の変化を起こすことが阻止される。また、継手１が送給ボンプ（図示略）による振動を受けても、単層ではなく耐圧性の高いベローズ管２の耐圧性構造から、振動は伸縮吸収されると共に、フランジ部３，３間に介装された皿バネ５ａ，５ａと緩衝材５ｂ，５ｂの弾性作用によっても振動が吸収されて振動が伝達されることもない。    Such an anti-vibration joint 1 is a system in which a pair of left and right flange portions 3 and 3 are connected by a rod-like body 5, so that even if a high-pressure fluid circulates in the pipe of the joint 1, the axial extension, etc. The change is prevented. Further, even if the joint 1 is subjected to vibration by a feeding pump (not shown), the vibration is stretched and absorbed from the pressure resistant structure of the bellows pipe 2 which is not a single layer and has high pressure resistance, and between the flange portions 3 and 3. The vibration is not absorbed and transmitted by the elastic action of the disc springs 5a, 5a and the cushioning materials 5b, 5b interposed between them.

したがって、このように振動や脈動などは、継手１の構造により遮断されて吐出側の配管などに伝達されず、配管状態を長期に宜って維持することが可能となる。例えば、２０ｋｇ／ｃ ｍ２以上の高層ビル等の高圧給水の継手として好適なものであるが、薄板を重ねた複数層のベロース管２よりなるたの、低コストに製作製することができないという欠点がある。また、ゴム製継手や金属製継手にはそれぞれに次のような問題もある。    Therefore, vibrations, pulsations, and the like are blocked by the structure of the joint 1 and are not transmitted to the discharge-side piping or the like, and the piping state can be maintained for a long time. For example, although it is suitable as a joint for high-pressure water supply such as a high-rise building of 20 kg / cm 2 or more, it is composed of a plurality of bellows tubes 2 in which thin plates are stacked, so that it cannot be manufactured and manufactured at low cost. There is. In addition, rubber joints and metal joints have the following problems.

すなわち、ゴム製継手は、外部から継手を被覆・保護するという面では優れているが、温度，圧力，流体などの使用される流体条件によって劣化や破壊を起こし易く、破損による水漏れなどの二次災害を起こし易いという問題がある。また、金属製継手は、温度，圧力，流体などの使用される流体条件がゴム製継手に比べて優れているが、反面、継手が波状のベローズ管として形成されていると両端部などに応力集中による疲労破壊が発生しやすく、亀裂などによりクレームの原因となる。さらに、両継手も内圧による推力（断面積×内圧）で、軸方向の伸びを防ぐためボルトを装着しているので防振性能が低下されてしまうなどの問題がある。    In other words, rubber joints are excellent in terms of covering and protecting the joints from the outside, but they tend to deteriorate or break down depending on the fluid conditions used, such as temperature, pressure, and fluid. There is a problem that it is easy to cause the next disaster. Metal joints are superior to rubber joints in terms of fluid conditions such as temperature, pressure, and fluid. On the other hand, if the joint is formed as a wavy bellows tube, stress is applied to both ends. Fatigue failure due to concentration tends to occur, and cracks cause complaints. In addition, both joints have thrust (cross-sectional area × internal pressure) due to internal pressure, and since the bolts are attached to prevent the axial extension, there is a problem that the vibration isolation performance is deteriorated.

この発明は、上記のような事情を鑑みたものでその目的は、ベローズ管を単層構造にしたままの状態でも優れた振動吸収性を有し、且つ、継手による振動や脈動などの伝達を減少することが可能な防振用ベローズ管継手を提供することにある。    The present invention has been made in view of the above circumstances, and its purpose is to have excellent vibration absorption even in a state where the bellows tube has a single-layer structure, and to transmit vibration, pulsation and the like by the joint. An object of the present invention is to provide a vibration-proof bellows pipe joint that can be reduced.

この発明は、そのような謀題を解決するために、請求項１記載のように、ベローズ管の両端側に一対のフランジ部を配し、上記ベローズ管内に高圧流体を送給させる防振用ベローズ管継手において、上記ベローズ管の外周部分は、軸方向の伸び止め部材による外装体によって被覆され、少なくともその軸方向の伸びが阻止されていることを特徴とする。また、請求項２記載のように、外装体による軸方向の伸び止め部材は、上記ベローズ管の外周部分を被覆する肉厚のゴム製又は樹脂製の外装体よりなり、上記外装体に内通されて一対のフランジ部間に掛け渡されるフランジ部間掛け渡し部材よりなることを特徴とする。また、請求項３記載のように、ベローズ管の中央部の谷部に立設される中間リングは、フランジ部間掛け渡し部材を維持することを特徴とする。    In order to solve such a problem, the present invention provides a vibration isolator in which a pair of flange portions are arranged on both ends of a bellows pipe and a high-pressure fluid is fed into the bellows pipe as described in claim 1. In the bellows pipe joint, the outer peripheral portion of the bellows pipe is covered with an exterior body formed of an axial extension preventing member, and at least the axial extension is prevented. According to a second aspect of the present invention, the axial extension preventing member by the exterior body is made of a thick rubber or resin exterior body that covers the outer peripheral portion of the bellows tube, and is internally connected to the exterior body. And a flange member spanning member spanned between the pair of flange portions. According to a third aspect of the present invention, the intermediate ring erected in the valley portion at the center of the bellows pipe maintains the spanning member between the flange portions.

請求項１記載の発明によれば、継手の内面側は金属製のベローズ管の単層構造としながらも、複層構造のベローズ管と比して充分に振動吸収性にも優れると共に、ゴム部材などに比して温度，圧力，流体などによる劣化を防止することができる低コストな継手を提供することができる。
また、ベローズ管の外周部分が軸方向の伸び止め部材による外装体によって被覆され、少なくともその軸方向の伸びが阻止されていることで、打痕などを回避することができ、且つ、金属製のベローズ管を均等に伸縮作動させ応力の集中化を防いで耐久性の向上を図ることができる。
請求項２記載の発明によれば、ベローズ管の内圧による推力による伸びを内蔵されているフランジ部間掛け渡し部材で阻止することができ、従来のボルトに比べて防振性能の向上は勿論として製品の簡易化を行うことができる。
また、請求項３記載の発明によれば、軸方向の伸び止め部材の中間リングが、ベローズ管の中央部の谷部に立設され、フランジ部間掛け渡し部材をゴム部材などの圧力に抗して良好に維持するこができる。According to the first aspect of the present invention, the inner surface side of the joint has a single layer structure of a metal bellows tube, but is sufficiently excellent in vibration absorption as compared with a multilayered bellows tube, and a rubber member. Compared to the above, it is possible to provide a low-cost joint that can prevent deterioration due to temperature, pressure, fluid, and the like.
In addition, the outer peripheral portion of the bellows tube is covered with an exterior body made of an axial extension preventing member, and at least the axial extension is prevented, so that dents and the like can be avoided, and metal The bellows tube can be expanded and contracted evenly to prevent stress concentration and improve durability.
According to the second aspect of the present invention, the extension due to the thrust due to the internal pressure of the bellows pipe can be prevented by the built-in flange portion spanning member, and as a matter of course, the vibration isolation performance is improved as compared with the conventional bolt. The product can be simplified.
According to the third aspect of the present invention, the intermediate ring of the axial extension preventing member is erected in the valley portion of the central portion of the bellows pipe, and the spanning member between the flange portions is resistant to the pressure of the rubber member or the like. Can be maintained well.

以下、この発明の実施するための最良の形態を図面に基づいて詳細に説明する。図１は、この発明の上半部を破砕した状態を示す正面図、図２は、図１の他の実施例を示す上半部の一部破砕正面図である。    Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings. FIG. 1 is a front view showing a state in which the upper half of the present invention is crushed, and FIG. 2 is a partially broken front view of the upper half showing another embodiment of FIG.

この継手１０の概略構成は、中央位置に配置される金属製のベローズ管１１と、金属製のベローズ管１１の左右側に配置される一対のフランジ部１２，１２と、ベローズ管１１の外周部分に被覆される伸び止め部材である外装体１４とによって構成されている。    The schematic configuration of the joint 10 includes a metal bellows tube 11 disposed at a central position, a pair of flange portions 12 and 12 disposed on the left and right sides of the metal bellows tube 11, and an outer peripheral portion of the bellows tube 11. It is comprised by the exterior body 14 which is an elongation stop member coat | covered by.

ベローズ管１１は、単層構造の金属製よりなり、山部１１ａと谷部１１ｂが連続する蛇腹部とされ、主に軸方向に伸縮可能な円筒状として形成されている。フランジ部１２，１２は、ベローズ管１１の両端側にそれぞれ配置されてベローズ管１１を固定的に装着する。    The bellows tube 11 is made of a metal having a single-layer structure, has a bellows portion in which a peak portion 11a and a valley portion 11b are continuous, and is mainly formed as a cylindrical shape that can expand and contract in the axial direction. The flange portions 12 and 12 are respectively arranged on both end sides of the bellows tube 11 and fixedly attach the bellows tube 11.

このベローズ管１１は金属製であればよいが、ステンレス鋼製であればより好適でありオーステナイト系ステンレス鋼製でもフェライト系ステンレス鋼製でもよい。    The bellows tube 11 may be made of metal, but is more preferably made of stainless steel, and may be made of austenitic stainless steel or ferritic stainless steel.

伸び止め部材である外装体１４は、両端側のフランジ部１２，１２に挟まれたベローズ管１１に外装され、ベローズ管１１を被覆しつつベローズ管１１の内圧による伸縮を阻止して伸び止め作用を果たす。
伸び止め作用を果たす素材としては、外装体としてゴム材又は合成樹脂材あるいは発泡樹脂材があり、ゴム材としてはニチレンプロピレン，ニトリルブタジエンゴム，クロロプレンゴム，ブチルゴム，アクリルゴム，エチレンアクルルゴムなど種々のものがあるが、防振用ゴム材としてはシリコンゴム，ポリイソプレンゴム，ポリブタジエンゴム，ポリクロロプレンゴム，フッ素ゴムなどが好適であり、適宜目的の用途に応じて選択される。The exterior body 14 that is an expansion preventing member is externally mounted on the bellows pipe 11 sandwiched between the flange portions 12 and 12 on both ends, and prevents expansion and contraction by covering the bellows pipe 11 and preventing expansion and contraction due to the internal pressure of the bellows pipe 11. Fulfill.
As materials that have an anti-elongation action, there are rubber materials, synthetic resin materials, and foamed resin materials as exterior bodies, and various rubber materials such as propylene rubber, nitrile butadiene rubber, chloroprene rubber, butyl rubber, acrylic rubber, and ethylene acrole rubber. Among them, silicon rubber, polyisoprene rubber, polybutadiene rubber, polychloroprene rubber, fluorine rubber and the like are suitable as the rubber material for vibration isolation, and are appropriately selected according to the intended use.

合成樹脂材としては、塩化ビニール，ポリスチレン，耐衝撃性ポリスチレン，低密度ポリエチレン，高密度ポリエチレン，ポリプロピレンなどがコスト面でも優れているが、ポリスチレンを二酸化炭素で多孔質化しスポンジ化した発泡樹脂材としたものも有効である。Synthetic resin materials such as vinyl chloride, polystyrene, high-impact polystyrene, low-density polyethylene, high-density polyethylene, and polypropylene are also excellent in terms of cost. It is also effective.

この継手１０のより具体的構造について説明する。蛇腹状に形成された円筒状の単眉構造のベローズ管１１は、その両端側においてストレートな円筒端部に形成され、左右のフランジ部１２，１２の取付け孔１２ａ，１２ａの間隙に外側端部と面一となるように差し込まれている。また、左右のフランジ部１２，１２の取付け孔１２ａ，１２ａと、ベローズ管１１のストレートな円筒端部との間隙は、パイブ１３，１３が差し込まれ、特に図中左側のフランジ部１２とパイプ１３はフランジ部１２より延設されてフランジ部１２の外周と面一となるように折曲されている。この結合方法は、上記の方法に限定されず適宜設計変更が可能である。なお、図中の黒部分は溶接部分を示している。    A more specific structure of the joint 10 will be described. A bellows tube 11 having a cylindrical single eyebrow structure formed in a bellows shape is formed at a straight cylindrical end portion at both ends thereof, and an outer end portion is provided in the gap between the mounting holes 12a and 12a of the left and right flange portions 12 and 12. It is inserted to be flush with. Further, the pipes 13 and 13 are inserted into the gaps between the mounting holes 12a and 12a of the left and right flange portions 12 and 12 and the straight cylindrical end portion of the bellows tube 11, and in particular, the left flange portion 12 and the pipe 13 are inserted in the drawing. Is bent from the flange portion 12 so as to be flush with the outer periphery of the flange portion 12. This coupling method is not limited to the above-described method, and the design can be changed as appropriate. In addition, the black part in a figure has shown the welding part.

伸び止め部材である外装体１４は、両端側のフランジ部１２，１２に挟まれたベローズ管１１の外周部に取付けられるもので、主として両フランジ部１２，１２の軸方向の保護と伸び止めを行うものであり、ベローズ管１１の保護はゴム製の外装体１４による被覆で行い、伸び止め作用は左右に張った金属製のワイヤーローブ１６によって行う。なお、径方向の伸び止め作用も軸方向に比べて少ないが考慮にいれることとなる。    The exterior body 14 which is an expansion preventing member is attached to the outer peripheral portion of the bellows tube 11 sandwiched between the flange portions 12 and 12 on both ends, and mainly protects and extends in the axial direction of the flange portions 12 and 12. The bellows tube 11 is protected by covering with a rubber outer body 14, and the anti-elongation action is performed by a metal wire lobe 16 stretched from side to side. In addition, although the anti-stretching action in the radial direction is smaller than that in the axial direction, it is taken into consideration.

伸び止め部材に用いるものは、金属製のワイヤーロープとして説明したがこれに限定されず適宜設計変更が可能であり、例えば細い金属製のワイヤーローブを撚り合わせたものなどでもよく、両フランジ部１２，１２に間に架るベローズ管１１の長を堅牢に一定に維持できるものであれば適宜設計変更が可能である。    Although the material used for the stretch preventing member has been described as a metal wire rope, the invention is not limited to this, and the design can be changed as appropriate. For example, a material obtained by twisting thin metal wire lobes may be used. As long as the length of the bellows tube 11 extending between the first and second members 12 can be maintained firmly and constant, the design can be changed as appropriate.

すなわち、このゴム製の外装体１４は、ワイヤーローブ１６を張った状態でゴム部材を加硫する。左右方向に張った状態で設置されるワイヤーローブ１６は、その両端部がボルト１７及びナット１８により径方向に固定されている。    That is, the rubber exterior body 14 vulcanizes the rubber member with the wire lobe 16 stretched. Both ends of the wire lobe 16 installed in a state of being stretched in the left-right direction are fixed in the radial direction by bolts 17 and nuts 18.

また、１９は中間リングであり、ベローズ管１１の中央部に設けられ谷部１１ｂに固定され、孔１９ａにワイヤーローブ１６が挿通されて良好に張った状態に維持するものである。    Reference numeral 19 denotes an intermediate ring, which is provided at the center of the bellows tube 11 and is fixed to the trough 11b, and the wire lobe 16 is inserted into the hole 19a so as to maintain a good tension.

このように、この発明によれば、左右側を一対のフランジ部１２，１２とし、継手１０の内面側を金属製の単層構造のベローズ管１１とし、且つ、その外面側をゴム製の外装体１５により被覆すると共に、ゴム製の外装体１５は左右側のフランジ部１２，１２に亘るワイヤーロープ１６を張った状態で架け渡す構成とされているので、複層構造のベローズ管に比して低コストに製作可能であり、しかも左右のフランジ部同士間は棒状体が架け渡されず、ワイヤーローブ１６の作用により伸縮を阻止することができる。    Thus, according to the present invention, the left and right sides are a pair of flange portions 12, 12, the inner surface side of the joint 10 is a metal single-layer bellows tube 11, and the outer surface side is a rubber exterior. Since the outer sheath 15 made of rubber is covered with the wire rope 16 extending over the flange portions 12 and 12 on the left and right sides, the outer sheath 15 made of rubber is covered with the body 15, so that it is compared with a bellows pipe having a multilayer structure. In addition, the rod-shaped body is not bridged between the left and right flange portions, and expansion and contraction can be prevented by the action of the wire lobe 16.

図２に示したものは、ワイヤーロープ１６の架け渡し状態の他例を示すものであり、その両端部がボルト１７及びナット１８により軸方向に固定されている。このように、ボルト１７とナット１８の位置は適宜設計変更が可能である。すなわち、フランジ部間掛け渡し部材１６としての止着は、ボルト１７，ナット１８の止着に限定されずあらゆる方法が想定される。    FIG. 2 shows another example of the state in which the wire rope 16 is bridged, and both ends thereof are fixed in the axial direction by bolts 17 and nuts 18. As described above, the design of the positions of the bolt 17 and the nut 18 can be appropriately changed. In other words, the fastening as the flange portion spanning member 16 is not limited to the fastening of the bolt 17 and the nut 18, and any method can be assumed.

伸び止め部材である外装体１４は、被覆体１５を一定厚みに形成するだけでなく、径方向あるいは軸方向に介在される伸び止め部材を埋設することでも可能であり、外装体１４を素材面から補強すると共に、補強材をまぶすことにより達成する。補強材の素材については上記したあらゆる素材を考慮することができる。    The exterior body 14 which is an extension preventing member can be formed not only by forming the covering body 15 with a constant thickness but also by embedding an extension prevention member interposed in the radial direction or the axial direction. This is achieved by applying the reinforcing material together with the reinforcement. All the above-mentioned materials can be considered for the material of the reinforcing material.

以上のように構成されたこの発明によれば、継手の内面側は金属製のベローズ管であるため、ゴム部材に比して温度，圧力，流体などによる劣化を防止することができる。また、継手の外面側はゴム製又は合成樹脂製の外装体で被覆されて保護されているので、打痕などを回避することができると共に、金属製のベローズ管を均等に伸縮作動させ応力の集中化を防ぐことができる。
さらに、ゴム製又は合成樹脂製の外装体は、金属製のベローズ管の内圧による推力による伸びを、内蔵されているフランジ部間掛け渡し部材で阻止することができ、従来のボルトなどに比べて防振性能の向上は勿論として製品の簡易化を行うことができる。According to the present invention configured as described above, since the inner surface side of the joint is a metal bellows tube, deterioration due to temperature, pressure, fluid, and the like can be prevented as compared with a rubber member. In addition, since the outer surface side of the joint is covered and protected by a rubber or synthetic resin exterior body, it is possible to avoid dents and the like, and the metal bellows tube can be expanded and contracted evenly to reduce the stress. Centralization can be prevented.
Furthermore, the exterior body made of rubber or synthetic resin can prevent the extension caused by the internal pressure of the metal bellows pipe by the built-in flange part spanning member, compared to conventional bolts etc. Of course, the product can be simplified as well as the improvement of the vibration isolation performance.

なお、その他ボンブの吐出側や吸入側の防振継手のみならず、配管の温度変化による伸縮や変位なども吸収できる継手としても使用が可能であり、さらにバルブの急開閉で生ずる流速の変化に起因するノイズなども消音することができる。    It can be used not only for vibration isolation joints on the discharge side and suction side of the bomb, but also for joints that can absorb expansion and contraction and displacement due to temperature changes in the piping. The resulting noise can also be silenced.
