In the gas cutoff valve device shown in FIG. 10 in the open state, a cutoff signal is input to the solenoid coil 1A of the self-holding solenoid 1 in case of an emergency such as gas leak. As a result, an electric current flows through the solenoid coil 1A, and the magnetic flux generated at this time causes the plunger 2 to descend and the valve body 3 to abut on the fixed valve seat 5 and the movable valve seat 6 to close the valve. When the emergency situation such as gas leak is recovered, the shutoff signal disappears, and the magnetic flux pushing down the valve body 3 disappears. Then, when the cap 12 is removed and the return button 10 is pushed in, the other end of the return rod 9 pushes up the movable valve seat 6 and the valve body 3 moves to the plunger 2
Is lifted and its upper end surface is attracted to the permanent magnet 1B, and the valve is opened.

The operation of the gas cutoff valve device will be described below.
When a cutoff signal is input to the electromagnetic coil 30, a magnetic flux is generated, which circulates to the fixed iron core 28-plunger 23-iron piece 31-permanent magnet 32-yoke 27-fixed iron core 28 to cancel the magnetic flux circulated by the permanent magnet 32. As a result, the suction force of the fixed iron core 28 is lost. Therefore, the plunger 23 is lowered by the spring force of the coil spring 26, and the valve body 22 comes into contact with the fixed valve seat 21 to close the valve. This state is shown in FIG. Next, when the cutoff signal disappears, the return operation is performed. When the knob portion 34B is grasped with a finger and pulled up, the plunger 23 is attracted to the fixed iron core 28 which is attracted by the magnetic flux from the permanent magnet 32. The valve is opened. This state is shown in FIG. Then the knob 34B
When the finger holding is released, the return rod 34 returns to the state of FIG. 1 by the spring force of the return spring 35.

If the attraction force and the restoring force of the return spring 35 are set to be larger than the force of the coil spring 26 for urging the valve body 22, the plunger 23 is moved to the attraction portion 24C when the finger pressing the knob portion 34B is released. While adsorbed, the valve returns to the open position as shown in FIG. In order to increase the attraction force when the return rod 34 is pushed, the return rod 34 and the attraction portion 34C are made of a magnetic material having a high magnetic permeability.
