Claims

[Scope of utility model registration request]

This is a type of pipe joint in which the valve bodies built into the socket and plug move back to open the flow path, and a cylindrical holder with an open front and a closed rear end is inserted into the flow path of the cylindrical body of the socket using support legs. be supported and provided;
A valve body is slidably fitted into this holder and is urged forward by a first spring supported by the holder to come into contact with a valve seat provided on the inner peripheral surface of the flow path of the main body cylinder. A hole is formed in the body in the axial direction, and in this hole, a second spring supported by the valve body and having a larger elastic force than the first spring springs forward so that its tip protrudes in front of the valve body and connects with the socket. A pipe joint made by slidably fitting a valve pusher rod that comes into contact with the valve body built into the plug and moves back when pressed when the plug is connected.
