Claims

[Claims for Utility Model Registration] 1. When the plug is inserted into the socket, the internal valve is opened, and at the same time, the locking ball of the socket engages with the circumferential groove of the plug, and the sliding ring of the socket engages with the locking ball. In a pipe fitting configured to move to a connection holding position that prevents protrusion in the outer circumferential direction and maintain the connected state, the sliding ring position detection operates by detecting the movement of the sliding ring to the connection holding position. A pipe joint with a switch. 2. A pipe connection device using the pipe joint according to claim 1, wherein a solenoid valve is provided in a pipeline on the supply side of the pipe joint, and the solenoid valve is opened by the operation of a sliding ring position detection switch. 3. A pressure switch is installed in the pipe line between the pipe fitting and the solenoid valve, and the timer is activated by the operation of the sliding ring position detection switch, and the solenoid valve is opened by closing the timer contacts, and the pressure switch is further activated. 3. The piping connection device according to claim 2, wherein the solenoid valve is kept open and a contact of the timer is opened. 4. The pipe connection device according to claim 3, wherein the pipe joint is provided with a connection indicator light, and the connection indicator light is turned on when the pressure switch is operated.
