Claims

[Scope of utility model registration request]

A fixed valve body 2 having a communication hole 2c on the circumferential surface of the end on the coupling side is provided inside the female body 1, and a cylindrical valve body having seal rings 3a on both inner surfaces is provided between the female body 1 and the fixed valve body 2. The valve body 3 is disposed with a spring bias toward the connection side, and when separated, the female joint A seals the communication hole 2c of the fixed valve body from both sides with the seal ring 3a, and is connected to the large diameter portion 11a on the piping connection side. Side small diameter portion 11b
A poppet valve 12 is disposed within the center hole 11c of a cylindrical male body 11 with a spring biased toward the coupling side, and an annular fluid chamber 16a is provided inside the male body 11 at least on the coupling side. A seal ring 19 is provided on both sides, and when separated, the annular chamber 16a is sealed from both sides by the seal ring, and a male joint B is provided, which is shielded from the center hole 11c and communicates the center hole 11c with the atmosphere. A pipe joint in which an annular chamber 16a and the female communication hole 2c, which communicate with each other, are sealed from both sides by a seal ring 19.
