Title: Low-pressure piping pipe joint
Inventor: MATSUMOTO SHIGEYUKI
IPC: F16L21/08
Filed: 1996-11-01
Abstract: PROBLEM TO BE SOLVED: To facilitate inserting a connecting end part of a pipe into the socket of a joint body with human power for connection by forming one slit in a circumferential direction on the inner periphery wall of the socket of the joint body for obtaining spring characteristics, and fitting a presser ring which is formed with a protrusion part of angle slope shape on its inner periphery surface. SOLUTION: For the connecting work of a low-pressure pipe, at first, a presser ring 13 is fitted onto the outer periphery of the connection end part 5a of a pipe 5, and an O ring 4 is fitted onto the front end of the connection end part 5a. When the connection end part 5a is inserted in the socket 2 of the joint body 1, the connection end part 5a is inserted in the socket 2 as a result of the O ring 4 being compressed and its diameter being shrunk. The diameter of the presser ring 13 is shrunk by using a clip 14. After it is inserted in the socket 2, the clip 14 is released, and then the diameter of the presser ring 13 is extended to adhere to the inner periphery wall of the socket 2.  In this condition, when the O ring 4 starts to move with the internal pressure of the pipe, the O ring 4 gets over a protrusion part 12 of the presser ring 13, so as to be compressed for shrinking its diameter, thus it is possible to prevent the O ring 4 from jumping out to the outside.
