じるプラグを設けた管継手。 It consists of a socket and a plug that are removably connected by operating a sleeve, and when the two are connected, the tips of the valves built into each other come into contact and push each other, opening the valves and communicating the fluid passages of the connected socket and plug. In this pipe joint, the tip of the main cylinder of the socket protrudes in the centripetal direction over the entire circumference, each part is a valve seat with the same radius, and the entire circumference of the end face of the part is equipped with a large area fluid pressure receiver. As a surface,
A compression spring is used to bias a sliding inner cylindrical body, which has a protrusion that maintains the fluid pressure receiving surface in contact with the fluid when the socket and plug are connected, and a small area of the fluid pressure receiving surface around the entire rear end surface, to a predetermined position. When the inner cylinder is not connected to the plug, it is biased by a compression spring and moves forward, applying a fluid pressure higher than the set pressure to the inner cylinder. A pipe joint provided with a plug that causes a valve head to abut against the valve seat and close a fluid passage as the inner cylindrical body retreats when the large area portion receives the plug.
