Claims (1)

[Claims for Utility Model Registration] (1) A lock ball 12 that engages and disengages from a circumferential groove 321 formed on the outer peripheral surface of the plug main cylinder 30 is held movably in a centrifugal direction, and A socket main cylinder 10 is fitted with a lock ball operating cylinder 13 having a surface for pressing in the centripetal direction and a gap for enabling movement in the centrifugal direction, and a lock ball operating cylinder 13 is slidably fitted in the axial direction. The opening tip has a valve seat that moves toward and away from the valve body, which is disposed at a proper position so that its axis coincides with the axis of the socket main cylinder 10. In the socket of the pipe joint, which is provided with an internal cylinder 15 that is provided so as to be slidable in the direction, an internal cylinder operating cylinder 17 that slides the internal cylinder 15 by rotational operation is connected to the socket main cylinder 10.
The lock ball operating cylinder 13 is brought close to the outer circumferential surface of the socket and is fitted in a column so as to be able to come into contact with and separate from the lock ball operating cylinder 13, and furthermore, on the opposing end surfaces of both operating cylinders, a socket protruding from the outer peripheral surface of the socket main cylinder is provided on the lock ball operating cylinder side. An opening 171 into which the L-shaped opening groove 13 that guides the provided operating barrel lock pin 14 is inserted into the operating barrel lock pin 14 that has come out of the L-shaped opening groove 13 on the inner barrel operating barrel 17 side.
Sockets for pipe fittings each equipped with . (2) The base of the plug cylinder 32 to be inserted into the pipe fitting socket 1 according to claim (1) is integrally connected to the adapter 30 with a cap nut 33 screwed onto the outer circumference,
A plug for a pipe joint in which an elastic ring 31 is fitted to a connecting surface between a plug cylinder 32 and an adapter 30 to allow the plug cylinder 32 to swing. (3) Attach the pipe fittings described in claim (1) to the ends of fixed pipes installed along walls, partitions, or inside the walls, etc., with the ends of the fixed pipes and/or their branch pipes facing upward. Fix the socket with the plug insertion hole facing upward, and on the other hand, fix the plug according to claim (2) with the tip facing downward at the end of the fluid flow opening of a hot water supply device such as a gas water boiler, and A piping connection system in which the plug is connected to the socket by being dropped from above.
