Claims

A joint with a valve having an internal flow path, and a valve mechanism capable of switching 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 shaft hole extending at least in a joint axial direction to form at least a part of the internal flow path, the shaft hole facing an opening of the counterpart joint , and the shaft hole being separated from the opening of the counterpart joint A joint body provided in a fixed state at a position to
The joint body is slidably disposed in the shaft hole, and has a center hole, a seat portion, and a seal end surface forming a part of the internal flow path, and the seal end surface is an opening of the counterpart joint. It is possible to move forward and backward between a connection position where the opening and the center hole can be communicated with each other while abutting the periphery of the opening and closing the periphery of the opening, and a separation position where the seal end face is separated from the mating joint. A slide bush supported by the joint body,
A biasing means interposed between the joint main body and the slide bush to bias the slide bush toward the connection position;
A forward position through which the valve portion is inserted into the shaft hole and the central hole and can be seated on the seat portion, and the valve portion passes through the opening and enters the counterpart joint; and A valve body member supported by the joint body so that the valve part can move forward and backward between a retreat position where the valve part retreats from the counterpart joint ;
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 to block the internal flow path, and the slide bush is used as an urging force of the urging means. Accordingly, the valve body member moves forward to the forward movement position, so that the valve portion of the valve body member separates from the seat portion of the slide bush and opens the internal flow path. And a valve joint, wherein the slide bush is advanced to the connection position by the urging force of the urging means.

2. The joint with valve according to claim 1, further comprising drive means for moving the valve body member forward and backward between the forward position and the backward position.

The valve body member has a piston portion on the base end side rearward of the valve portion, and the joint body stores the piston portion and is divided into a front chamber and a rear chamber by the piston portion. 3. The valved joint according to claim 1, further comprising: an assist flow path for guiding the fluid pressure supplied to the internal flow path to a rear chamber of the cylinder chamber.

A joint device comprising the joint with a valve according to any one of claims 1 to 3 and the counterpart joint having a counterpart internal passage communicating with the opening, wherein the counterpart joint communicates with the opening and the opening. And a mating joint body having a mating shaft hole extending at least in the joint axial direction and forming at least a part of the mating internal flow path,
When the valve body member moves forward to the advance position in a state where the joint body is fixed at a position where the opening of the counterpart joint and the shaft hole of the joint body face each other and separate from each other, the biasing means The sliding bush advances to the connecting position by the urging force of the sliding bush, and the valve portion separated from the seat portion of the sliding bush passes through the opening and enters the mating joint, thereby causing the mating internal flow. A joint device characterized in that a passage and an internal flow path of the joint with valve are communicated with each other.

The mating joint is inserted into a mating shaft hole of the mating joint body, and a valve closing position that closes the opening and a valve opening that opens backward from the valve closing position to the inside of the mating shaft hole. A counterpart valve member supported by the counterpart joint body so as to be able to advance and retract between positions, and a counterpart biasing means for biasing the counterpart valve member toward the valve closing position,
When the valve body member of the joint with valve is advanced to the advance position, the valve body member is configured to push the counterpart valve member to the open position against the biasing force of the counterpart biasing means. The joint device according to claim 4, wherein

One of the joint with valve and the counterpart joint is arranged on the supply equipment side having a fluid supply means for supplying fluid to the receiving equipment and a first pipe group consisting of a plurality of first pipes. In addition, each of the first pipes is connected to the other, and the other of the joint with valve and the counterpart joint can be connected to each of the joints provided on the supply equipment side. As described above, the plurality of pipes are arranged on the receiving equipment side and are connected to the second pipes of the second pipe group including the plurality of second pipes provided on the receiving equipment side. The joint device according to claim 4 or 5 .
