Description

本発明の実施形態は、管継手に関するものである。   Embodiments of the present invention relate to a pipe joint.

雄型及び雌型の継手部材の一対を接続して、配管を接続する管継手において、筒状の継手部材の内部に流路の開閉を行うためのバルブ有し、前記雄型、雌型の継手部材を着脱する際に内部の流体が漏れない機構のものがある。例えば、両継手部材共に、バルブにゴム等の材質の弾性体であるシール材を有し、接続及び脱離時も流体の漏れがない機構である。   A pipe joint that connects a pair of male and female joint members and connects pipes has a valve for opening and closing a flow path inside the tubular joint member. There is a mechanism that prevents internal fluid from leaking when the joint member is attached or detached. For example, both joint members have a seal material, which is an elastic body made of rubber or the like, in the valve, so that no fluid leaks even when connected and disconnected.

図4は、従来のバルブを有する管継手の構成を示す図である。図4Aは、雄型の継手部材(雄型部材)の断面図である。図4Bは、雌型の継手部材(雌型部材)の断面図である。図4Cは、バルブ450とバルブストップ411の斜視図である。図4Dは、雌型部材と雄型部材を結合した状態を示した図である。   FIG. 4 is a diagram showing a configuration of a pipe joint having a conventional valve. FIG. 4A is a cross-sectional view of a male joint member (male member). FIG. 4B is a cross-sectional view of a female joint member (female member). FIG. 4C is a perspective view of the valve 450 and the valve stop 411. FIG. 4D is a diagram illustrating a state in which the female member and the male member are coupled to each other.

図4A,図4Cにおいて、雄型部材410は、雄型部材本体415、アダプタ416、アダプタOリング417、バルブストップ411、バルブスプリング412、バルブ450を有する。バルブ450はバルブ本体413とバルブシール414とを有する。バルブシール414は、材質がゴム等の弾性体であって、筒状のバルブ本体413に取り付けられる。バルブ450は、バルブストップ411に取り付けられたバルブスプリング412で押さえられた状態で、雄型部材本体415に挿入され、アダプタOリング417を装着したアダプタ416で固定される。そして、図4Cに示すように筒状のバルブストップ411は、流体移動用の複数の孔418と、バルブ450の移動の際のガイドとなる孔419を有する。   4A and 4C, the male member 410 includes a male member main body 415, an adapter 416, an adapter O-ring 417, a valve stop 411, a valve spring 412, and a valve 450. The valve 450 includes a valve main body 413 and a valve seal 414. The valve seal 414 is made of an elastic material such as rubber and is attached to the tubular valve body 413. The valve 450 is inserted into the male member body 415 while being pressed by a valve spring 412 attached to the valve stop 411, and is fixed by an adapter 416 equipped with an adapter O-ring 417. As shown in FIG. 4C, the tubular valve stop 411 has a plurality of holes 418 for fluid movement and a hole 419 that serves as a guide when the valve 450 moves.

一方、図4Bに示す雌型の継手部材である雌型部材420は、バルブストップ421、バルブスプリング422、バルブ460、バルブシール閉塞部材(以下、ピントルと称する)423、スナップリング426を有する。バルブ460は、バルブ本体425、バルブシール424、Vシール429を有し、Vシール429は材質がゴム等の弾性体で、バルブ本体425に取り付けられる。バルブ460は、バルブストップ421に取り付けられたバルブスプリング422で押さえられた状態で、ピントル423に当接している。ピントル423は、スナップリング426によりバルブストップ421に固定される。バルブストップ421は、雌型部材本体427とアダプタ428で固定される。   4B includes a valve stop 421, a valve spring 422, a valve 460, a valve seal closing member (hereinafter referred to as a pintle) 423, and a snap ring 426. The valve 460 includes a valve main body 425, a valve seal 424, and a V seal 429. The V seal 429 is made of an elastic material such as rubber and is attached to the valve main body 425. The valve 460 is in contact with the pintle 423 while being pressed by a valve spring 422 attached to the valve stop 421. The pintle 423 is fixed to the valve stop 421 by a snap ring 426. The valve stop 421 is fixed by a female member main body 427 and an adapter 428.

図4Dは、雌型部材420と雄型部材410を結合した状態を示した図である。雌型部材420のピントル423と雄型部材410のバルブシール414、雄型部材410のバルブスプリング412の弾性力で当接し、Vシール425と共に流路内の流体の漏れを防止する。雄型部材本体415の先端部と雌型部材420のバルブシール424は、バルブスプリング422の弾性力で当接し、流路内の流体の漏れを防止する。雌型部材420と雄型部材410を分離する際も、雌型部材420と雄型部材410が完全に離れるまで、前記3つのシール部材で流体の漏れを防止する。   FIG. 4D is a view showing a state in which the female member 420 and the male member 410 are combined. The elastic force of the pintle 423 of the female member 420, the valve seal 414 of the male member 410, and the valve spring 412 of the male member 410 is brought into contact with the V seal 425 to prevent fluid leakage in the flow path. The distal end portion of the male member main body 415 and the valve seal 424 of the female member 420 are brought into contact with each other by the elastic force of the valve spring 422 to prevent leakage of fluid in the flow path. Even when the female member 420 and the male member 410 are separated, fluid leakage is prevented by the three seal members until the female member 420 and the male member 410 are completely separated.

前記雌型部材420と雄型部材410の着脱時の雄型部材側のバルブ450の移動は、バルブストップ411の孔419をガイドにして行っているため、孔419の長さが短いとバルブ450が傾斜して雄型部材本体415に弾接し、漏れが発生する可能性がある。漏れ防止のためにバルブストップ411が長くする必要があるため、圧力損失が大きくなる。   The movement of the valve 450 on the male member side when the female member 420 and the male member 410 are attached / detached is performed using the hole 419 of the valve stop 411 as a guide. May incline and elastically contact the male member main body 415 to cause leakage. Since it is necessary to lengthen the valve stop 411 in order to prevent leakage, the pressure loss increases.

The valve seal 113 of the valve 220 abuts against the step 310 at the tip of the male member in a leak-proof state by the elastic force of the valve spring 111.

図1Bは、雌型の雌型部材120の断面図である。雌型部材120は、着脱部品129、配管取付部品128、シール用Oリング132、操作部材(以下、リテーナと称する)130、131、シール用Oリング133、バルブシール閉塞部材(以下、ピントルと称する)127、バルブストップ121、スナップリング123、バルブスプリング122、バルブ140、内部に図示しない雄型部材110の挿入孔を有する。   FIG. 1B is a cross-sectional view of a female female member 120. The female member 120 includes an attachment / detachment component 129, a pipe attachment component 128, a sealing O-ring 132, operating members (hereinafter referred to as retainers) 130 and 131, a sealing O-ring 133, and a valve seal closing member (hereinafter referred to as pintle). ) 127, a valve stop 121, a snap ring 123, a valve spring 122, a valve 140, and an insertion hole for a male member 110 (not shown).

雌側のバルブ140は、バルブ本体124、Vシール125、バルブシール126を有する。バルブ140は、バルブストップ421に取り付けられたバルブスプリング422で押さえられた状態で、ピントル423に当接している。ピントル423は、スナップリング426によりバルブストップ421に固定される。バルブストップ421は、雌型部材本体427とアダプタ428で固定される。バルブ140は、バルブスプリング122の弾性力によりピントル127の裏側に漏洩防止状態で当接する。バルブ本体124と着脱部品129は、Vシール125により漏洩防止状態となる。   The female valve 140 includes a valve main body 124, a V seal 125, and a valve seal 126.

The valve 140 abuts against the back side of the pintle 127 in a leak-proof state by the elastic force of the valve spring 122. The valve main body 124 and the detachable component 129 are in a leakage prevention state by the V seal 125.

図2は、雄型部材110のバルブ220の形状を示す図で、筒状のバルブ本体112にバルブシール113を取り付けた状態の図である。図2Aは前記バルブ本体112の斜視図、図2Bはバルブシール113と反対側の軸方向から見た図(バルブシール113側を正面とした場合の背面図)であり、図2Cは軸に対して垂直方向から見た図(平面図)である。   FIG. 2 is a view showing the shape of the valve 220 of the male member 110, and shows a state in which the valve seal 113 is attached to the tubular valve body 112. 2A is a perspective view of the valve body 112, FIG. 2B is a view as seen from the axial direction opposite to the valve seal 113 (back view when the valve seal 113 side is the front), and FIG. It is the figure (plan view) seen from the vertical direction.

雄側のバルブ220は、バルブ本体112を樹脂材質で一体成形し、バルブ移動時のガイドである少なくとも3枚以上の複数のフィン211を有する事で、移動時にバルブ220の傾斜が発生しにくい。複数のフィン211は、バルブ220の軸上で等角度にあるのが望ましい。図2では、90度ずつ4等分したプラス形状が長手方向に形成された立方体を示したが、これに限定されるものではない。例えば、3等分乃至6等分で構成したフィンであっても良い。バルブ本体112を樹脂成形することで、フィン211の形状が比較的自由な形状とすることができ、圧力損失も小さくなる。   The male valve 220 is formed by integrally molding the valve main body 112 with a resin material and has at least three or more fins 211 as a guide when the valve is moved, so that the valve 220 is less likely to be inclined during the movement. The plurality of fins 211 are preferably equiangular on the axis of the valve 220. Although FIG. 2 shows a cube in which a plus shape divided by 90 degrees into four equal parts is formed in the longitudinal direction, it is not limited to this. For example, it may be a fin composed of three or six equal parts. By resin-molding the valve body 112, the shape of the fin 211 can be made relatively free, and the pressure loss is also reduced.

図3は、実施形態の雌型部材120と雄型部材110を結合した時の接続図である。
雌型部材120の挿入孔に向けて、雄型部材110の筒状着脱部(図1Aの右端から雄型部材中央部の溝311の左端まで)を挿入するとき、雄側のバルブ220の複数のフィン211が雄型部材110の内周面をガイドにして、スムーズに移動することができる。そして、雄型部材110の先端部が雌型部材120のバルブシール126の位置まで当接すると、同時に雄側のバルブ220のバルブシール113が雌型部材120のピントル127に当接する。さらに、雄型部材110が図3の右側に移動すると、雄型部材110側は、バルブ220がピントル127に押されて、バルブスプリング111が縮み、気密性を保持していたバルブシール113が雄型部材先端の段310から離れて、雄型部材120内に流路が形成される。
FIG. 3 is a connection diagram when the female member 120 and the male member 110 of the embodiment are combined.
When the cylindrical attachment / detachment portion (from the right end of FIG. 1A to the left end of the groove 311 in the center of the male member) is inserted toward the insertion hole of the female member 120, a plurality of male valves 220 are inserted. The fin 211 can move smoothly with the inner peripheral surface of the male member 110 as a guide. When the tip of the male member 110 comes into contact with the position of the valve seal 126 of the female member 120, the valve seal 113 of the male valve 220 simultaneously contacts the pintle 127 of the female member 120. Further, when the male member 110 moves to the right side in FIG. 3, on the male member 110 side, the valve 220 is pushed by the pintle 127, the valve spring 111 is contracted, and the valve seal 113 which has been kept airtight is male. A flow path is formed in the male mold member 120 away from the step 310 at the tip of the mold member.

一方、雌型部材120側は、雌側のバルブ140が雄型部材110に押されて、バルブスプリング122が縮み、気密性を保持していたバルブシール126がピントル127から離れて、雌型部材120内にも流路が形成される。   On the other hand, on the female member 120 side, the female valve 140 is pushed by the male member 110, the valve spring 122 contracts, and the valve seal 126 that has been kept airtight is separated from the pintle 127, so that the female member A flow path is also formed in 120.

このように本実施形態によれば、雌型部材120のピントル127と雄型部材110のバルブシール113は、雄型部材110のバルブスプリング111の弾性力により漏洩防止状態で当接し、流路内の流体の漏れを防止する。雄型部材本体114の先端部と雌型部材120のバルブシール126は、バルブスプリング122の弾性力により漏洩防止状態で当接し、Vシール125及びシール用Oリング132と共に流路内の流体の漏れを防止する。   As described above, according to the present embodiment, the pintle 127 of the female member 120 and the valve seal 113 of the male member 110 are in contact with each other in a leak-proof state by the elastic force of the valve spring 111 of the male member 110, Prevent fluid leakage. The distal end of the male member main body 114 and the valve seal 126 of the female member 120 abut against each other in a leak-proof state by the elastic force of the valve spring 122, and together with the V seal 125 and the sealing O-ring 132, leakage of fluid in the flow path. To prevent.

なお、雄型部材110と雌型部材120の固定は、樹脂製の部品であるリテーナ130,131(樹脂製操作部材)を雄型部材110の中央部の溝311に嵌合し、リテーナに形成されたばねで押し付けることにより行われる。
実施形態の管継手の形状によれば、バルブストップ411を使用する必要がある従来の形状と比較すると流路面積が大きく、圧力損失が小さくすることができる。
The male member 110 and the female member 120 are fixed to each other by fitting retainers 130 and 131 (resin operation members), which are resin parts, into the groove 311 at the center of the male member 110, and forming the retainer. This is done by pressing with a spring that is made.
According to the shape of the pipe joint of the embodiment, the flow path area is large and the pressure loss can be reduced as compared with the conventional shape in which the valve stop 411 needs to be used.

(変形例)
本実施形態のバルブを、図1Aに示す雄型部材の構成でも使用可能である。また、バルブ本体112の材質は、射出成形粉末冶金などで一体成形可能な金属でも良い。さらに、フィン211と別部品に分けて成型し、接着、溶着等で1つの部品にしてもよい。
(Modification)
The valve of this embodiment can also be used in the configuration of the male member shown in FIG. 1A. The material of the valve body 112 may be a metal that can be integrally formed by injection molding powder metallurgy or the like. Further, the fin 211 may be divided into separate parts and molded into one part by bonding, welding, or the like.
