[0004] However, since each port is provided at only one position crossing the longitudinal hole, a large pressure loss is required, and it is necessary to align the socket and the plug at the time of connection. In addition, since a blind hole is formed by the socket covering the spring for biasing the valve means, the valve means and the washer, when the discharge material enters the blind hole, the discharge material includes liquid, Since the solid or gel-like substance is contained, there is a possibility that the solid substance or the gel-like substance is clogged in the blind hole of the socket. In such a case, it is necessary to disassemble the socket in order to remove the clogged discharge, and there is a problem that maintenance cannot be easily performed.

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object, and is a sanitary pipe joint which is connected to a socket with a plug.
A sleeve valve having an enlarged diameter portion at a connection end portion urged by a spring is slidably provided on an outer periphery of a cylinder body having a valve body at a connection end, and an outlet communicating with a flow path in the cylinder body. On the other hand, the plug is provided with a slide cylinder member having a valve portion at a connection end in a cylindrical plug body having a pressing portion for fitting and pressing the enlarged diameter portion of the sleeve valve. A slide port is slidably provided in the plug body via a spring provided on the outer periphery of the member, and a communication port communicating with a flow path in the slide cylinder member is provided in the slide cylinder member. The opening is made to penetrate from both sides so as to expose the spring and to face the communication port when the socket and the plug are connected.

While the socket and the plug are connected, the pressing portion of the plug body presses the sleeve valve to the rear of the cylinder against the elastic force of each spring, and is closed by the sleeve valve. The outlet of the cylindrical body is opened, and the slide cylindrical member in contact with the cylindrical body moves to the rear of the plug body to open the flow path of the plug body. The flow path between the socket and the plug is communicated via the outlet. In this case, the flow path from the socket cylinder to the opening of the plug main body of the plug and the flow path from the terminal opening of the slide cylinder member are in communication. At this time, since the communication port faces the opening, the fluid is caused to flow into the container from both sides of the flow path of the slide cylinder member and the opening, so that pressure loss is reduced.
