この発明は、エアーその他の気体を通過させる流通路内
の残圧を抜くようにしたバルブ付きの管継手に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a pipe joint with a valve that relieves residual pressure in a flow path through which air or other gases pass.
従来より、気体を通過させる管継手内の残圧を抜くため
には、接続している管を継手から外したり、或いは管の
先端に取り付けられている電磁バルブを手動で動かして
、圧力解放の操作をしていた。Traditionally, in order to release the residual pressure inside a pipe fitting that allows gas to pass through, it is necessary to remove the connected pipe from the fitting or manually operate the solenoid valve attached to the end of the pipe to release the pressure. was operating.
従って従来の管継手では、残圧の抜き取り操作が複雑で
、ワンタッチで容易に残圧を抜き取ることができなかっ
た。Therefore, with conventional pipe joints, the operation for removing the residual pressure is complicated, and the residual pressure cannot be easily removed with a single touch.
また、これら従来の管継手の部分に於いて、継手内を気
体が流通しているか否かを察知することもできなかった
。Furthermore, in these conventional pipe joints, it has not been possible to detect whether or not gas is flowing within the joint.
そこでこの発明では、管継手内の残圧をワンタッチの極

知ることができる、便利な残圧抜きバルブ付き管継手を
提供しようとするものである。Therefore, in this invention, the residual pressure inside the pipe joint can be removed by an extremely easy one-touch operation, and after the residual pressure is removed, the extraction path can be automatically closed again. The present invention aims to provide a convenient pipe joint with a residual pressure release valve that allows you to know whether or not gas is passing through the pipe joint by the same easy operation as releasing pressure.

に案内孔を閉鎖するストップバルブを没入可能として案
内孔に挿入し、さらに前記ストップバルブをスプリング
によって外部方向に押圧している構造とした。To this end, in the pipe joint of the present invention, a guide hole is provided that communicates with the outside from a part of the gas flow path, a step is formed in the guide hole, and the guide hole is in contact with the step to have a retaining structure and guide. A stop valve for closing the hole is retractably inserted into the guide hole, and the stop valve is further pressed outward by a spring.
またこの管継手は、ストップバルブの外端が、筐体より
外部に突出しておらず、ストップバルブの外周に装着し
たOリングが案内孔内に接合してシール構造を得て実施
することもできる。In addition, in this pipe joint, the outer end of the stop valve does not protrude outside from the casing, and an O-ring attached to the outer periphery of the stop valve can be joined into the guide hole to obtain a sealing structure. .
上記の構造を得た管継手は、ス)7ブバルブがスプリン

ブは没入可能であるため、内方に押圧すると没入して段
部との当接が外れ、流通路と外部が案内孔を介して連通
ずる。In the pipe joint with the above structure, the guide hole is closed because the 7 valve is always pressed outward by the spring and comes into contact with the stepped part, but this stop valve is retractable. Therefore, when pressed inward, it retracts and comes out of contact with the stepped portion, and the flow path and the outside communicate with each other via the guide hole.
従って、ストップバルブを押圧して没入させるのみの簡
単な操作で、残圧を抜き取ることができ、さらに、スト
ップバルブの押圧を放すとストップバルブはスプリング
の作用で自動的に復元し、再度案内孔を閉鎖する。Therefore, the residual pressure can be released by simply pressing and retracting the stop valve.Furthermore, when the pressure on the stop valve is released, the stop valve automatically returns to its original state due to the action of the spring and re-opens the guide hole. will be closed.
また継手内を気体が流通しているか否かを知るためには
、ストップバルブを押圧する。そこで案内孔からの気体
の漏れの状態をみれば流通が確認できる。Also, in order to know whether or not gas is flowing inside the joint, press the stop valve. Therefore, by looking at the state of gas leakage from the guide hole, the flow can be confirmed.
以下この発明の構成を、実施例として示した図面に従っ
て説明する。DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be described below with reference to the drawings shown as examples.
この管継手は、従来より周知のように、筐体(1)の一
部を管(2)を接続する管接続部(3)とし、他の一部
を、たとえば空気圧用シリンダーなどの機器類に取り付
ける装着部(4)としている。As is well known in the past, this pipe joint has a housing (1) with a part of the housing (1) serving as a pipe connection part (3) for connecting a pipe (2), and the other part of the housing (1) serving as a pipe connection part (3) for connecting a pipe (2) to a device such as a pneumatic cylinder. It is a mounting part (4) to be attached to.

の作用で逆止弁(6)を変形させてガイド(7)の端部
外周に形成した切欠部(図示せず)と筐体(1)内壁の
間から接続した機器類に至るようになっている。In the pipe joint of the illustrated embodiment, gas such as air passes through a flow path (5) leading from a connected pipe (2) to a mounting portion (4). The gas entering the flow path (5) from the pipe (2) deforms the check valve (6) under the action of atmospheric pressure and passes through the notch (not shown) formed on the outer periphery of the end of the guide (7) and the casing. Body (1) It is designed to reach the connected equipment from between the inner walls.
尚この逆止弁(6)は、気体が逆流した場合、逆流する
気体の圧を受けて筐体(1)内壁に密着し、逆流を防ぐ
ようになっている。In addition, when gas flows backward, the check valve (6) is adapted to receive the pressure of the gas flowing backward and come into close contact with the inner wall of the casing (1), thereby preventing the backward flow.
次にこの管継手の、残圧抜き構造について説明する。Next, the residual pressure release structure of this pipe joint will be explained.

内側に当接するようにしている。(11) is a stop valve inserted into the guide hole (8), and this stop valve (11) is connected to the step part (9).
It has a retaining structure and closes the guide hole (8). That is, the stop valve (11) is provided with a protruding flange (12) so that the flange (12) comes into contact with the inside of the stepped portion (9).

すると没入して段部(9)との当接が外れ、流通路(5
)と外部が案内孔(8)を介して連通ずる。In the pipe joint with the above structure, the stop valve (11) is always pressed outward by the spring (13) and comes into contact with the step (9), so the guide hole (8) is always closed. However, since this stop valve (11) is retractable, when pressed inward against the spring (13), it retracts and comes out of contact with the stepped portion (9), causing the flow path (5
) and the outside communicate through the guide hole (8).
そこで、ストップバルブ(11)を押圧して没入させる

ルブ(11)と案内孔(8)内壁間にできた間隙から流
出し、残圧は抜き取られる。Therefore, when the stop valve (11) is pressed and immersed, the gas at the flow pressure in the flow passage (5) flows out from the gap created between the stop valve (11) and the inner wall of the guide hole (8). Residual pressure is removed.
さらにストップバルブ(11)の押圧を放すとストップ
バルブ(11)はスプリング(13)の作用で自動的に
復元し、再度案内孔(8)を閉鎖する。Further, when the pressure on the stop valve (11) is released, the stop valve (11) is automatically restored by the action of the spring (13) and closes the guide hole (8) again.
また継手内を気体が流通しているか否かを知るためには
、ストップバルブ(11)を押圧する。そこで案内孔(
8)からの気体の漏れの状態をみれば流通の有無がわか
る。Moreover, in order to know whether or not gas is flowing in the joint, the stop valve (11) is pressed. There, the guide hole (
8) The presence or absence of circulation can be determined by looking at the state of gas leakage.
尚、ストップバルブ(11)の頭部を筐体(1)から突
