Description

本発明は、各種油圧機器への油圧配管の接続や、配管同士の接続/切り離しを行うのに用いられる弁付き継手及びこの弁付き継手を備えた継手装置に関するものである。   The present invention relates to a joint with a valve used for connecting a hydraulic pipe to various hydraulic devices and connecting / disconnecting the pipes to each other and a joint device including the joint with the valve.

従来、前記のような継手装置として、例えば特許文献1に記載されたものが知られている。   Conventionally, what was described in patent document 1, for example as a joint apparatus as mentioned above is known.

この継手装置は、下向きに吊設された第1継手と、この第1継手の下方の位置に上向きに設けられた第2継手とを備えている。前記第1継手には、この第1継手の内部流路を塞ぐ閉弁位置と該内部流路を開放する開弁位置との間で切換可能な弁が設けられている。   The joint device includes a first joint suspended downward and a second joint provided upward at a position below the first joint. The first joint is provided with a valve that can be switched between a valve closing position for closing the internal flow path of the first joint and a valve opening position for opening the internal flow path.

そして、両継手が離間した状態ではスプリング等によって前記第1継手の弁が前記閉弁位置に保持される一方、前記第2継手が油圧シリンダ等で持ち上げられることにより、該第2継手が前記第1継手の弁と当接して該弁を前記スプリングの弾発力に抗して開弁させるとともに両継手が接続されるようになっている。   In a state where both joints are separated, the valve of the first joint is held in the closed position by a spring or the like, while the second joint is lifted by a hydraulic cylinder or the like, so that the second joint is The valve is brought into contact with the valve of one joint to open the valve against the elastic force of the spring, and both joints are connected.

特開平10−238680号公報(第3〜5頁、図1)Japanese Patent Laid-Open No. 10-238680 (pages 3 to 5, FIG. 1)

しかしながら、前記従来の継手装置では、継手同士の接続及び切り離しと弁の開閉を行うために一方の継手(第2継手)全体を油圧シリンダ等で昇降させなければならず、大きな駆動力が必要になるとともに、第2継手を第1継手との接続位置へ正確に導くためにガイドピン等を含む複雑な案内機構が必要になる。   However, in the conventional joint device, in order to connect and disconnect the joints and to open / close the valve, one joint (second joint) must be moved up and down by a hydraulic cylinder or the like, which requires a large driving force. In addition, a complicated guide mechanism including a guide pin or the like is required to accurately guide the second joint to the connection position with the first joint.

したがって、前記従来の継手装置では、装置全体が総じて複雑化及び大型化してしまうという問題があった。   Therefore, the conventional joint device has a problem that the entire device is generally complicated and enlarged.

なお、前記従来の継手装置の第1継手と第2継手とが水平方向に対向して設けられていたとしても、第2継手の全体を油圧シリンダ等で水平移動させなければならない以上、同様の問題が起こりうる。   Even if the first joint and the second joint of the conventional joint device are provided to face each other in the horizontal direction, the same is true as long as the entire second joint has to be moved horizontally by a hydraulic cylinder or the like. Problems can occur.

本発明は、上記実情に鑑みてなされたものであり、大掛かりな設備を要することなく継手同士の接続及び切り離しを行えるようにすることを解決すべき技術課題とするものである。   This invention is made | formed in view of the said situation, and makes it the technical subject which should be solved to enable it to perform connection and disconnection of joints, without requiring a large-scale installation.

前記課題を解決する本発明の弁付き継手は、内部流路と、該内部流路を塞ぐ状態と該内部流路を相手方継手に設けられた開口に接続する状態とに切換可能な弁機構とを有する弁付き継手であって、少なくとも継手軸方向に延びて前記内部流路の少なくとも一部を形成する軸孔を有し、該軸孔が前記相手方継手の開口と対向する位置に設けられる継手本体と、前記継手本体の前記軸孔内に摺動可能に配設されるとともに、前記内部流路の一部を形成する中心孔、座部及びシール端面を有し、該シール端面が前記相手方継手の開口の周縁部に当接して該開口の周囲を塞ぎながら該開口と該中心孔とを連通させうる接続位置と該シール端面が該相手側継手から離間する離間位置との間で進退動可能となるように前記継手本体に支持されたスライドブッシュと、前記継手本体と前記スライドブッシュとの間に介装されて該スライドブッシュを前記接続位置側に付勢する付勢手段と、前記軸孔及び前記中心孔内に挿通されるとともに、前記座部に着座可能な弁部を先端に有し、該弁部が前記開口を通過して前記相手方継手内へ進入する前進位置と該弁部が該相手方継手から後退する後退位置との間で進退動可能となるように前記継手本体に支持された弁体部材と、前記弁体部材を前記前進位置と前記後退位置との間で進退動させるための駆動手段とを備え、前記弁体部材は前記弁部よりも後方の基端側にピストン部を有し、前記継手本体は、前記ピストン部を格納して該ピストン部により前側室と後側室とに区画されるシリンダ室と、前記内部流路に供給された流体圧力を前記シリンダ室の後側室に導くためのアシスト流路とを有しており、前記弁体部材が前記後退位置まで後退することにより該弁体部材の弁部が前記スライドブッシュの座部に着座して前記内部流路を塞ぐとともに該スライドブッシュを前記付勢手段の付勢力に抗して前記離間位置まで後退させる一方、前記弁体部材が前記前進位置まで前進することにより該弁体部材の弁部が前記スライドブッシュの座部から離座して前記内部流路を前記開口に接続するとともに該スライドブッシュを前記付勢手段の付勢力で前記接続位置まで前進させるように構成されていることを特徴とするものである。   A joint with a valve of the present invention that solves the above problems is an internal flow path, a valve mechanism that can be switched between a state of closing the internal flow path and a state of connecting the internal flow path to an opening provided in a counterpart joint. A joint with a valve having a shaft hole extending at least in the joint axial direction to form at least a part of the internal flow path, and the shaft hole provided at a position facing the opening of the counterpart joint A main body, and a center hole that forms a part of the internal flow path, a seat portion, and a seal end surface, and is slidably disposed in the shaft hole of the joint main body, and the seal end surface is the counterpart Advancing and retreating between a connection position where the opening and the center hole can be communicated with each other while abutting the periphery of the opening of the joint and closing the periphery of the opening, and a separated position where the seal end face is separated from the mating joint A slide block supported by the joint body so as to be possible. And an urging means interposed between the joint body and the slide bush to urge the slide bush toward the connection position, and inserted into the shaft hole and the center hole, A valve portion that can be seated on the seat portion is provided at the tip, and the valve portion passes between the opening and enters the counterpart joint, and a retreat position where the valve portion retracts from the counterpart joint. A valve body member supported by the joint body so as to be capable of advancing and retreating; and a drive means for moving the valve body member forward and backward between the forward movement position and the backward movement position. Has a piston part on the proximal side behind the valve part, and the joint body stores the piston part and is divided into a front chamber and a rear chamber by the piston part, and the internal The fluid pressure supplied to the flow path is changed after the cylinder chamber. An assist flow path for guiding to the chamber, and when the valve body member is retracted to the retracted position, the valve portion of the valve body member is seated on the seat portion of the slide bush and the internal flow path And the slide bush is retracted to the separation position against the biasing force of the biasing means, while the valve body member is advanced to the advance position, whereby the valve portion of the valve body member is moved to the slide bush. The seat is separated from the seat portion to connect the internal flow path to the opening, and the slide bush is advanced to the connection position by the biasing force of the biasing means. is there.

また、前記課題を解決する本発明の継手装置は、前記弁付き継手と、前記開口に通じる相手側内部通路を有する前記相手方継手とを備えた継手装置であって、該相手方継手は前記開口と該開口に通じるとともに少なくとも継手軸方向に延びて前記相手側内部流路の少なくとも一部を形成する相手側軸孔とを有する相手方継手本体を備え、前記相手方継手の開口と前記継手本体の前記軸孔とが対向する位置に該継手本体が固定された状態で前記弁体部材が前記前進位置まで前進することにより、前記付勢手段の付勢力で前記スライドブッシュが前記接続位置まで前進するとともに、該スライドブッシュの前記座部から離座した前記弁部が前記開口を通過して前記相手方継手内へ進入することにより前記相手方内部流路と前記弁付き継手の内部流路とが連通されるように構成されていることを特徴とするものである。   Moreover, the joint device of the present invention that solves the above-mentioned problem is a joint device that includes the valved joint and the counterpart joint having a counterpart internal passage that communicates with the opening, and the counterpart joint includes the opening and the joint. A mating joint body having a mating shaft hole that communicates with the opening and extends at least in the joint axial direction to form at least a part of the mating internal flow path; and the opening of the mating joint and the shaft of the joint body While the joint body is fixed at a position facing the hole, the valve body member advances to the advance position, whereby the slide bush advances to the connection position by the urging force of the urging means, and When the valve part separated from the seat part of the slide bush passes through the opening and enters the counterpart joint, the internal flow of the counterpart internal flow path and the joint with valve is established. And it is characterized in that it is configured to be passed are communicated.

以上の構成において、弁付き継手の弁体部材を前記後退位置まで後退させると、該弁体部材の弁部がスライドブッシュの座部に着座して弁付き継手の内部流路を塞ぐとともに該スライドブッシュを付勢手段の付勢力に抗して前記離間位置まで後退させるため、これにより継手同士が切り離されるとともに弁付き継手が閉弁される。これに対し、弁付き継手の弁体部材を前記前進位置まで前進させると、付勢手段の付勢力でスライドブッシュが前記接続位置まで前進するとともに該スライドブッシュの座部から前記弁部が離座するため、これにより弁付き継手が開弁されるとともに両継手が接続されて流体が流通可能となる。   In the above configuration, when the valve body member of the valve joint is retracted to the retracted position, the valve portion of the valve body member is seated on the seat portion of the slide bush to block the internal flow path of the valve joint and the slide In order to retract the bush against the urging force of the urging means to the separated position, the joints are thereby disconnected and the valved joint is closed. On the other hand, when the valve body member of the joint with valve is advanced to the advance position, the slide bush is advanced to the connection position by the urging force of the urging means, and the valve portion is separated from the seat portion of the slide bush. Therefore, the valved joint is opened and both joints are connected to allow fluid to flow.

このように、弁付き継手のうちの弁体部材のみを前進及び後退させるだけで継手同士の接続及び切り離しと弁付き継手の開弁及び閉弁とを同時に行うことが可能であるため、従来のように継手全体を移動させなければならない装置に比べ、必要駆動力が大幅に軽減され、簡単な設備で継手の接続及び切り離しができる。このため、故障等の発生を抑制できるとともに、継手の接続状態において流体漏れ等を抑制して信頼性を向上させることが可能になる。   In this way, since it is possible to simultaneously connect and disconnect the joints and open and close the valved joints only by moving forward and backward only the valve body member of the valved joints, Thus, the required driving force is greatly reduced compared to a device that must move the entire joint, and the joint can be connected and disconnected with simple equipment. For this reason, the occurrence of a failure or the like can be suppressed, and fluid leakage or the like can be suppressed in the connected state of the joint to improve reliability.

また、前記弁付き継手の前記弁体部材は、前記弁部よりも後方の基端側にピストン部を有し、前記継手本体は、前記ピストン部を格納して該ピストン部により前側室と後側室とに区画されるシリンダ室と、前記内部流路に供給された流体圧力を前記シリンダ室の後側室に導くためのアシスト流路とを有している。このため、弁付き継手の内部流路に供給された流体圧力を利用して前記前進位置への弁体部材の駆動を補助することができ、その分だけ駆動手段の必要駆動力を軽減させることが可能となる。特に、前記相手方継手から弁付き継手に流体が流入する場合において、その流体圧力が高い場合、すなわち、弁体部材を後退させようとする力が大きい場合であっても、これに比較的小さな駆動力で対抗でき、弁体部材を前進位置に保持しておくことが可能となる。   Further, the valve body member of the joint with valve has a piston portion on a proximal end side rearward of the valve portion, and the joint body stores the piston portion and the front chamber and the rear are stored by the piston portion. A cylinder chamber partitioned into a side chamber and an assist channel for guiding the fluid pressure supplied to the internal channel to the rear chamber of the cylinder chamber are provided. For this reason, the drive of the valve body member to the advance position can be assisted using the fluid pressure supplied to the internal flow path of the valved joint, and the required driving force of the driving means is reduced accordingly. Is possible. In particular, when fluid flows into the valved joint from the counterpart joint, even when the fluid pressure is high, that is, when the force to retract the valve body member is large, a relatively small drive is required. It can be countered by force, and the valve body member can be held in the advanced position.

また、前記継手装置において、前記相手方継手は、前記相手方継手本体の相手方軸孔内に挿通されるとともに、前記開口を塞ぐ閉弁位置と該閉弁位置から前記相手方軸孔の内方へ後退して前記開口を開く開弁位置との間で進退動可能となるように前記相手方継手本体に支持された相手方弁部材と、該相手方弁部材を前記閉弁位置側に付勢する相手方付勢手段とを備え、前記弁付き継手の弁体部材が前記前進位置まで前進することにより該弁体部材が前記相手方付勢手段の付勢力に抗して前記相手方弁部材を前記開弁位置まで押し込むように構成されていることが好ましい。この態様によれば、継手同士が切り離されたときに、相手方継手においても、自己の弁機構により前記開口を塞いで該開口からの流体漏れを防ぐことが可能となる。また、相手方継手の弁機構の開閉動作を前記弁体部材の進退動を利用して単一操作で簡単に行わせることが可能になる。   Further, in the joint device, the counterpart joint is inserted into the counterpart shaft hole of the counterpart joint body, and retracts from the valve closing position for closing the opening and the valve closing position to the inside of the counterpart shaft hole. A counterpart valve member supported by the counterpart joint body so as to be able to move forward and backward with respect to the valve opening position where the opening is opened, and a counterpart biasing means for biasing the counterpart valve member toward the valve closing position. The valve body member of the joint with valve is advanced to the advance position so that the valve body member pushes the counterpart valve member to the open position against the urging force of the counterpart urging means. It is preferable that it is comprised. According to this aspect, when the joints are separated from each other, even in the counterpart joint, it is possible to prevent the fluid leakage from the opening by closing the opening with its own valve mechanism. Further, the opening / closing operation of the valve mechanism of the counterpart joint can be easily performed by a single operation using the advance / retreat of the valve body member.

さらに、前記継手装置は、好適な態様において、前記弁付き継手及び前記相手方継手のうちの一方は、受給設備に流体を供給するための流体供給手段及び複数個の第1配管よりなる第1配管群をもつ供給設備側に複数個配設されるとともに各該第1配管にそれぞれが接続される一方、前記弁付き継手及び前記相手方継手のうちの他方は、該供給設備側に設けられた各該継手とそれぞれが対応して連結可能となるように該受給設備側に複数個配設されるとともに該受給設備側に設けられた複数個の第2配管よりなる第2配管群の各該第2配管にそれぞれが接続される。この態様によれば、対となる弁付き継手及び相手方継手毎に接続及び切り離しの操作が可能なる。このため、各配管毎に流体を供給するか否かの制御が可能になる。また、例えば複数の相手方継手が配設された固定プレートに対して複数の弁付き継手が配設された可動プレートを移動させることにより複数の弁付き継手及び相手方継手を一括して接続及び切り離しを行う場合と比較して、必要駆動力が大幅に軽減され、極めて簡単な設備で継手の接続及び切り離しができる。   Furthermore, in a preferred aspect, the joint device is configured such that one of the joint with valve and the counterpart joint is a fluid supply means for supplying fluid to a receiving facility and a first pipe comprising a plurality of first pipes. A plurality of groups are arranged on the supply equipment side having a group and are connected to the first pipes, respectively, while the other of the joint with valve and the counterpart joint is provided on the supply equipment side. A plurality of second pipe groups comprising a plurality of second pipes provided on the receiving equipment side and arranged on the receiving equipment side so that the joints can be connected to each other correspondingly. Each is connected to two pipes. According to this aspect, connection and disconnection operations can be performed for each paired valve joint and counterpart joint. For this reason, it is possible to control whether or not the fluid is supplied to each pipe. Further, for example, by moving a movable plate having a plurality of valve joints with respect to a fixed plate having a plurality of counterpart joints, a plurality of valve joints and a counterpart joint can be connected and disconnected in a lump. Compared with the case where it is performed, the required driving force is greatly reduced, and the coupling can be connected and disconnected with extremely simple equipment.

以上のように本発明は、継手本体に設けられたスライドブッシュを相手方継手と接続される接続位置と相手方継手から離間する離間位置との間で進退動可能とするとともに、このスライドブッシュを接続位置側に付勢するようにし、このスライドブッシュの中心孔に挿通された弁体部材を駆動手段を用いて後退させることにより該弁体部材の弁部をスライドブッシュの座部に着座させて内部流路を塞ぐとともに該スライドブッシュを付勢手段の付勢力に抗して前記離間位置まで後退させる一方、前記弁体部材を駆動手段を用いて前進させることにより前記付勢力でスライドブッシュを前記接続位置まで前進させるとともに該スライドブッシュの座部から前記弁部を離座させるようにしたものであるから、継手全体を移動させることなく、前記弁体部材を操作するだけの簡単な構成で継手同士の接続及び切り離しを行うことが可能となる。   As described above, the present invention enables the slide bush provided on the joint main body to move forward and backward between a connection position where the slide bush is connected to the counterpart joint and a separated position which is separated from the counterpart joint. The valve body member inserted through the center hole of the slide bush is retracted by using a driving means so that the valve portion of the valve body member is seated on the seat portion of the slide bush and the internal flow is The slide bush is closed against the urging force of the urging means and retracted to the separated position while the valve body member is moved forward by using the driving means, and the slide bush is moved by the urging force to the connection position. And the valve portion is separated from the seat portion of the slide bush, without moving the entire joint, It is possible to perform the connection and disconnection of the coupling between a simple configuration of merely operating the body member.

また、アシスト流路を有していることにより、弁付き継手の内部流路に供給された流体圧力を利用して前記前進位置への弁体部材の駆動を補助することができ、その分だけ駆動手段の必要駆動力を軽減させることが可能となる。   In addition, by having the assist flow path, it is possible to assist the drive of the valve body member to the advance position by using the fluid pressure supplied to the internal flow path of the valved joint. It becomes possible to reduce the required driving force of the driving means.

(A) shows the state where the joints are cut off, and FIGS. 2 and 3 (b) show the state where the joints are connected.

まず、第2継手J2について説明する。この第2継手J2は、第2内部流路形成ブロック12と背壁ブロック14とから構成された第2継手本体(相手方継手本体)10を備えている。第2内部流路形成ブロック12は、同ブロック12をその中心軸(継手軸)に沿って貫通する貫通孔(相手方軸孔)12aと、この貫通孔12aの中間部につながる配管接続口12bと、前記貫通孔12aの前端(図1及び図2では右端)の開口12cとを有している。そして、前記貫通孔12aの後端の開口を塞ぐように前記背壁ブロック14が前記第2内部流路形成ブロック12の後端面に固定されている。したがって、この第2継手本体10には、前記配管接続口12bから前記貫通孔12aを経由して前記開口12cに至る第2内部流路(相手方内部流路)が形成されている。   First, the second joint J2 will be described. The second joint J2 includes a second joint body (mating joint body) 10 composed of a second internal flow path forming block 12 and a back wall block 14. The second internal flow path forming block 12 includes a through hole (mating shaft hole) 12a penetrating the block 12 along its central axis (joint axis), and a pipe connection port 12b connected to an intermediate portion of the through hole 12a. And an opening 12c at the front end (right end in FIGS. 1 and 2) of the through hole 12a. And the said back wall block 14 is being fixed to the rear-end surface of the said 2nd internal flow-path formation block 12 so that the opening of the rear end of the said through-hole 12a may be plugged up. Accordingly, the second joint body 10 is formed with a second internal flow path (a counterpart internal flow path) extending from the pipe connection port 12b to the opening 12c via the through hole 12a.

前記貫通孔12a内には、本発明に係る相手方弁部材に相当する第2弁軸16が装填されている。この第2弁軸16は、前端側に大径の第2弁部16aを有するとともに、後端側に被支持軸部16bを有している。そして、第2弁軸16の全体が前記貫通孔12aの中心軸上に位置する状態で、前記被支持軸部16bが軸方向に進退動可能となるように軸受け18を介して前記背壁ブロック14に支持されている。この軸方向の進退動により、第2弁軸16は、第2弁部16aの外周面が前記貫通孔12aの開口12cの内周縁部(第2座部)に当接、着座して該開口12cを塞ぐ閉弁位置と、該開口12cの内周縁部から第2弁部16aが離れて第2継手本体12の貫通孔12aの内方に後退し該開口12cを開く開弁位置とに切替可能となっている。   A second valve shaft 16 corresponding to the counterpart valve member according to the present invention is loaded in the through hole 12a. The second valve shaft 16 has a large-diameter second valve portion 16a on the front end side and a supported shaft portion 16b on the rear end side. The back wall block is interposed via the bearing 18 so that the supported shaft portion 16b can move forward and backward in the axial direction in a state where the entire second valve shaft 16 is located on the central axis of the through hole 12a. 14 is supported.

As shown in FIGS. 3A and 3B, the outer periphery of the first valve portion 36 has a taper in a direction to reduce the diameter toward the rear end side (right side of the drawing) of the first valve shaft 34. A tapered seal surface 36a is formed, and the taper seal surface 36a can be seated on the front end of the inner peripheral surface of the slide bush 26 from the front end side (left side of the figure) of the first valve shaft 34. A seat portion 26a (see FIG. 3A) is formed, and the first internal flow path is blocked from the front by the taper seal surface 36a of the first valve portion 36 contacting and seating on the seat portion 26a. (Valve closed).

前記第1弁軸34の後端にはリング状の駆動用ピストン部材38が固定される一方、前記シリンダブロック24の後端部にはこの駆動用ピストン部材38を格納する駆動用シリンダ室40が形成され、この駆動用シリンダ室40内が駆動用ピストン部材38によって前側室40aと後側室40bとに区画されている。   A ring-shaped driving piston member 38 is fixed to the rear end of the first valve shaft 34, and a driving cylinder chamber 40 for storing the driving piston member 38 is disposed at the rear end of the cylinder block 24. The driving cylinder chamber 40 is formed into a front chamber 40a and a rear chamber 40b by a driving piston member 38.

さらに、前記シリンダブロック24には前記前側室40a及び後側室40bにそれぞれ通ずるポート42、44が設けられており、各ポート42、44が共通の油圧回路46に接続されている。この油圧回路46は、図略の油圧源及び切換弁を含み、該切換弁の作動によって、前記前側室40aに圧油を供給して後側室40b内の油を図略のタンクに逃がすことにより第1弁軸34を図1に示す後退位置まで後退させる後退駆動状態と、前記後側室40bに圧油を供給して前側室40a内の油をタンクに逃がすことにより第1弁軸34を図2に示す前進位置まで前進させる前進駆動状態とに切換可能となっている。   Further, the cylinder block 24 is provided with ports 42 and 44 that communicate with the front chamber 40a and the rear chamber 40b, respectively, and the ports 42 and 44 are connected to a common hydraulic circuit 46. The hydraulic circuit 46 includes a hydraulic source (not shown) and a switching valve. By operating the switching valve, the hydraulic circuit 46 supplies pressure oil to the front chamber 40a and releases the oil in the rear chamber 40b to a tank (not shown). The reverse drive state in which the first valve shaft 34 is retracted to the retracted position shown in FIG. 1, and the first valve shaft 34 is illustrated by supplying pressure oil to the rear chamber 40b and letting the oil in the front chamber 40a escape to the tank. It is possible to switch to a forward drive state for moving forward to the forward position shown in FIG.

ここで、前記第1弁軸の後退位置は、図1及び図3(a)に示されるように、第1弁軸34の第1弁部36が第2継手J2の前記開口12cから後方に離脱してテーパシール面36aがスライドブッシュ26の第1座部26aに接触して着座し、かつ、その接触状態のままスライドブッシュ26を前記離間位置まで後退させるように設定されている。これに対して前記第1弁軸の前進位置は、図2及び図3(b)に示されるように、前記第1弁部36が第2継手J2の第2弁軸16に当接してこの第2弁軸16を前記第2圧縮コイルばね17の弾発力に抗して開弁位置まで押し込みながら該第1弁部36が前記開口12cを通過して前記貫通孔12aの内方まで進入するように設定されている。   Here, as shown in FIGS. 1 and 3A, the retracted position of the first valve shaft is such that the first valve portion 36 of the first valve shaft 34 moves rearward from the opening 12c of the second joint J2. The taper seal surface 36a is separated from the first seat portion 26a of the slide bush 26 and is seated, and the slide bush 26 is set back to the spaced position with the contact state. On the other hand, as shown in FIGS. 2 and 3B, the forward position of the first valve shaft is determined by the first valve portion 36 coming into contact with the second valve shaft 16 of the second joint J2. The first valve portion 36 passes through the opening 12c and enters the inside of the through hole 12a while pushing the second valve shaft 16 to the valve opening position against the elastic force of the second compression coil spring 17. It is set to be.

すなわち、この継手装置では、前記駆動用ピストン部材38及び駆動用シリンダ室40により構成された油圧シリンダと、前記油圧回路46とにより、第1弁軸34を前記前進位置と前記後退位置との間で進退動させるための駆動手段が構成されている。   That is, in this coupling device, the first valve shaft 34 is moved between the forward position and the backward position by the hydraulic cylinder constituted by the driving piston member 38 and the driving cylinder chamber 40 and the hydraulic circuit 46. The drive means for advancing and retreating is configured.

さらに、この実施の形態では、前記第1弁軸34の中間部にリング状の補助ピストン部材48が固定されるとともに、前記シリンダブロック24にこの補助ピストン部材48を格納するアシスト用シリンダ室50が形成されており、このアシスト用シリンダ室50内が補助ピストン部材48によって前側室50aと後側室50bとに区画されている。さらに、前記第1内部流路形成ブロック22及びシリンダブロック24には、前記配管接続口22b内の油を前記後側室50bに導くためのアシスト流路52が両ブロック22及び24にまたがって形成されている。   Further, in this embodiment, a ring-shaped auxiliary piston member 48 is fixed to an intermediate portion of the first valve shaft 34 and an assist cylinder chamber 50 for storing the auxiliary piston member 48 in the cylinder block 24 is provided. The assist cylinder chamber 50 is divided into a front chamber 50 a and a rear chamber 50 b by an auxiliary piston member 48. Further, an assist channel 52 for guiding the oil in the pipe connection port 22b to the rear chamber 50b is formed in the first internal channel forming block 22 and the cylinder block 24 across the blocks 22 and 24. ing.

なお、シリンダブロック24には、前記補助ピストン部材48の前進時に前記前側室50a内の空気を図略のタンクに逃がすための排出路54が形成されている。   The cylinder block 24 is formed with a discharge passage 54 for allowing air in the front chamber 50a to escape to a tank (not shown) when the auxiliary piston member 48 moves forward.

次に、この継手装置の使用要領及び作用を説明する。   Next, the usage procedure and operation of the joint device will be described.

まず、両継手J1及びJ2を図示のように互いに近接する位置に固定するとともに、両継手J1、J2の配管接続口12b、22bに適当な配管を接続しておく。その際、油圧回路は後退駆動状態にして第1弁軸34を図1及び図3(a)に示す後退位置まで後退させておく。   First, both joints J1 and J2 are fixed at positions close to each other as shown, and appropriate pipes are connected to the pipe connection ports 12b and 22b of both joints J1 and J2. At that time, the hydraulic circuit is set in the reverse drive state, and the first valve shaft 34 is moved back to the reverse position shown in FIGS. 1 and 3A.

この状態では、第1弁軸34の先端部に設けられた第1弁部36のテーパシール面36aがスライドブッシュ26の第1座部26aに接触、着座して第1内部流路を前方から塞ぐ(すなわち閉弁する)するとともに、スライドブッシュ26が第1圧縮コイルばね30の弾発力に抗して離間位置まで後退することにより該スライドブッシュ26のシールリング27が第2継手J2の第2内部流路形成ブロック12の前側面から離間している。また、第2継手J2においても、圧縮コイルばね16の弾発力によって第2弁軸16が前記開口12cを塞ぐ閉弁位置に保持されている。   In this state, the taper seal surface 36a of the first valve portion 36 provided at the distal end portion of the first valve shaft 34 comes into contact with and sits on the first seat portion 26a of the slide bush 26, and the first internal flow path is viewed from the front. In addition to closing (that is, closing), the slide bush 26 moves back to the separated position against the elastic force of the first compression coil spring 30, whereby the seal ring 27 of the slide bush 26 is moved to the second joint J2. 2 Separated from the front side surface of the internal flow path forming block 12. Also in the second joint J2, the second valve shaft 16 is held at the valve closing position where the opening 12c is closed by the elastic force of the compression coil spring 16.

この状態から両前記配管を接続したいときには、前記油圧回路46を前進駆動状態に切り換えて第1弁軸34を前進位置まで前進させる。この第1弁軸34の前進に伴い、該第1弁軸34における第1弁部36のテーパシール面36aと第1座部26aとの接触状態を保ちながらスライドブッシュ26が第1圧縮コイルばね30の弾発力により前進し、ついには該スライドブッシュ26のシールリング27が第2継手J2側の第2内部流路形成ブロック12の前端面における前記開口12cの周縁部に当接して該開口12cの周囲を塞ぐ接続位置で止まる。   When it is desired to connect both the pipes from this state, the hydraulic circuit 46 is switched to the forward drive state and the first valve shaft 34 is advanced to the forward position. As the first valve shaft 34 advances, the slide bush 26 is moved to the first compression coil spring while maintaining the contact state between the taper seal surface 36a of the first valve portion 36 of the first valve shaft 34 and the first seat portion 26a. The seal ring 27 of the slide bush 26 finally comes into contact with the peripheral edge of the opening 12c on the front end surface of the second internal flow path forming block 12 on the second joint J2 side. It stops at the connection position that closes the periphery of 12c.

この後、第1弁軸34はさらに前進を続け、第1弁軸34の第1弁部36が第2継手J2の第2弁軸16に当接してこれを前記第2圧縮コイルばね17の弾発力に抗して後退させながら該第1弁部36が前記開口12cを通って前記貫通孔12aの内方まで進入する位置、すなわち図2及び図3(b)に示す前進位置に到達する。この状態では、第1弁部36が第1座部26aから離座するとともに、第2弁軸16が前記開口12cから離間する開弁位置まで押し込まれているため、例えば配管接続口12b側から貫通孔12a内に流入する油は、前記開口12c、スライドブッシュ26の中心孔及び貫通孔22aを順次経由して配管接続口22bに接続された配管内へ送り込まれる。すなわち、第1及び第2継手J1及びJ2が完全に接続された状態となる。   Thereafter, the first valve shaft 34 continues to advance further, and the first valve portion 36 of the first valve shaft 34 abuts against the second valve shaft 16 of the second joint J2, and this is connected to the second compression coil spring 17. The first valve portion 36 reaches the position where it enters the inside of the through-hole 12a through the opening 12c, that is, the forward position shown in FIGS. 2 and 3 (b) while being retracted against the elastic force. To do. In this state, the first valve portion 36 is separated from the first seat portion 26a, and the second valve shaft 16 is pushed to the valve opening position away from the opening 12c. The oil flowing into the through hole 12a is fed into the pipe connected to the pipe connection port 22b through the opening 12c, the center hole of the slide bush 26 and the through hole 22a in this order. That is, the first and second joints J1 and J2 are completely connected.

このように、第1弁軸34及びスライドブッシュ26を動かすだけで継手J1、J2同士の接続及び切り離しができるため、従来のように継手全体を移送しなければならない装置に比べ、必要駆動力が大幅に軽減されるので、駆動手段を小型化できる。また、継手全体を接続位置へ導くための大掛かりな案内機構が不要になる。さらに、継手全体を移送する従来の装置では継手だけでなくこれに接続された配管も継手に連動して移動できるようにしなければならないが、この実施形態の装置では継手J1、J2に接続される配管を動かすための設備を省略できる。そして、第1弁軸34を駆動手段により操作すればこれに連動してスライドブッシュ26が自動的に接続位置と離間位置とに切り換えられることもあり、総じて装置全体が大幅に小型化及び簡素化される。   In this way, since the joints J1 and J2 can be connected and disconnected only by moving the first valve shaft 34 and the slide bush 26, the required driving force is lower than that of a conventional apparatus that has to transport the entire joint. Since it is greatly reduced, the drive means can be reduced in size. In addition, a large guide mechanism for guiding the entire joint to the connection position is not required. Furthermore, in the conventional apparatus for transferring the entire joint, not only the joint but also the pipe connected thereto must be able to move in conjunction with the joint. In the apparatus of this embodiment, the pipe is connected to the joints J1 and J2. Equipment for moving the piping can be omitted. Then, if the first valve shaft 34 is operated by the driving means, the slide bush 26 may be automatically switched between the connection position and the separation position in conjunction with this, so that the overall apparatus is greatly reduced in size and simplified. Is done.

さらに、この継手装置では、第2継手J2から第1継手J1へ流れる油の圧力がアシスト流路52を通ってアシスト用シリンダ室50の後側室50bに導かれることにより駆動アシスト力として作用するため、その分だけ油圧回路46の負担が軽減される。したがって、前記油の圧力が高い場合でも、油圧回路46による比較的小さな駆動力で、高圧に抗して第1弁軸34を図2及び図3(b)に示す前進位置に保っておくことが可能である。   Furthermore, in this joint device, the pressure of the oil flowing from the second joint J2 to the first joint J1 is guided to the rear chamber 50b of the assist cylinder chamber 50 through the assist flow path 52, thereby acting as a driving assist force. Thus, the load on the hydraulic circuit 46 is reduced by that amount. Therefore, even when the oil pressure is high, the first valve shaft 34 is kept at the advanced position shown in FIGS. 2 and 3B against the high pressure with a relatively small driving force by the hydraulic circuit 46. Is possible.

ただし、本発明において、相手方継手(図示の第2継手J2)から弁付き継手(図示の第1継手J1)へ流体が流されるものには限られないことは勿論である。   However, in the present invention, it is needless to say that the fluid is not limited to flow from the counterpart joint (the second joint J2 shown) to the joint with valve (the first joint J1 shown).

また、本発明では取り扱う流体の種類も問わず、前記油の他、水その他の種々の流体を取り扱うための継手として本発明を適用することが可能である。駆動手段の種類も、取扱い流体の圧力その他の仕様に応じて適宜設定すればよい。   Further, in the present invention, the present invention can be applied as a joint for handling water and other various fluids in addition to the oil, regardless of the type of fluid to be handled. The type of the driving means may be set as appropriate according to the pressure of the handled fluid and other specifications.

Specifically, the fitting portion 25 a of the air cylinder connection block 25 is fitted into the through hole 22 a of the first internal flow path forming block 22. An air cylinder 60 is connected to the air cylinder connection block 25 as driving means, and the telescopic rod 62 of the air cylinder 60 and the rear end of the first valve shaft 34 are connected in the air cylinder connection block 25. ing.

さらに、必要駆動力が小さい場合には、前記第1弁軸34の位置切換が例えば手動によるレバー操作によって行われるようにすることも可能である。   Furthermore, when the required driving force is small, the position of the first valve shaft 34 can be switched by, for example, a manual lever operation.
