ABSTRACT:
A socket of a pipe joint has a socket body, coupled to an end portion of a first fluid pipe, for removably receiving a plug coupled to an end portion of a second fluid pipe to be coupled to the first fluid pipe, a valve mechanism provided within the socket body and situated in an open position to allow passage of a fluid between the socket body and the plug when the plug is inserted in the socket body, and a lock mechanism for preventing removal of the plug from the socket body when the valve mechanism is situated in the open position. A hollow cylindrical valve receiving portion having a valve seat formed on an inner peripheral surface of the valve receiving portion, a valve body slidably situated within the valve receiving portion and having a valve head cooperating with the valve seat to constitute the valve mechanism, and a spring, supported by the valve receiving portion, for urging the valve body in a direction to bring the valve head into contact with the valve seat are constructed as a single assembly capable of being inserted in the socket body.
