Claims

[Scope of utility model registration request]

A fixed valve seat, a valve body that faces the fixed valve seat and can move toward and away from the fixed valve seat, a spring that biases this valve body in the valve-closing direction, and a restoring force of this spring. a holding mechanism that holds the valve body in an open state against the pressure; and an enclosing wall that is inserted inside the fixed valve seat and that is movable back and forth in the movement direction of the valve body and that is longer than the return stroke of the valve body. , a movable valve seat whose distal end edge presses against the valve body to close the inner fluid flow port when the valve body moves forward; The present invention is characterized by comprising a ring-shaped sealing member having a lip portion that is in contact with the surrounding wall of the movable valve seat for airtight sealing, and a push rod that is connected to the movable valve seat and moves the movable valve seat forward and backward. Shutoff valve device.
