Claims

[Scope of utility model registration request]

It has a pair of pipe joints coaxially joined to each other so as to be removable, and at least one of the pipe joints is pushed inward by the joining force with the other pipe joint to open a flow path. In the pipe joint device, the pipe joint is provided with a normally-closed valve and a seal member for sealing the joint, the seal member having a cylindrical shape, and the outer circumference of the pipe joint body of at least one of the pipe joints. It is fitted so as to be slidable in the axial direction, and is biased by a spring in the direction of protruding toward the distal end of the pipe fitting body, and the distal end is fitted onto the end face of the pipe fitting body of the other pipe fitting. A pipe joint device characterized by having a sealing surface for face-to-face contact.
