Claims

[Scope of claim for utility model registration] (1) A valve body having a valve chamber, an inlet provided at one end of the valve chamber, an outlet provided at the other end, and a valve provided between the inlet and the outlet within the valve chamber. a valve seat provided on the upstream side of the valve seat, a valve body that opens and closes the valve by approaching and separating from the valve seat, a spring means that biases the valve body in a direction away from the valve seat, and a valve seat. A plunger is provided on the downstream side of the valve chamber and contacts and separates from the valve element through the opening of the valve seat to separate the valve element from the valve seat, and a solenoid is provided at the end of the valve chamber and into which the plunger is inserted. A shutoff valve. (2) A valve body having a valve chamber, an inlet provided on the lower end side of the valve chamber, an outlet provided on the upper end side, an outlet side valve seat provided between the inlet and the outlet in the valve chamber, and the outlet. an inlet side valve seat provided below the side valve seat;
A separation pin is provided on the upstream side of the valve seat on the inlet side, and the tip portion moves forward and backward through the opening of the valve seat, and the valve seat is provided between the two valve seats. A ball valve element that selectively selects a valve position and a position where both valves open by contacting the above-mentioned separation pin, and a ball valve element that approaches and separates from the ball valve element from above to place the ball valve element on the outlet side valve seat. A shutoff valve comprising a plunger movable from a contact position to a contact position with an inlet valve seat, and a solenoid provided at the upper end of a valve chamber and into which the plunger is inserted. (3) A cutoff valve according to claim 1 or 2 of the utility model registration claim, a pipe line connected to the outlet of the cutoff valve, and a gas outlet provided at the tip of the pipe line; A gas piping system using a cutoff valve, comprising a switch means provided in the outlet portion and turned on and off by connection to the outlet, and applying an on/off signal of the switch means to a solenoid of the cutoff valve. Branched structure.
