断装置。[Claims for Utility Model Registration] 1. A valve seat formed at the opening of a gas flow path, a valve body disposed opposite to this valve seat and having a valve plate attached to the valve seat side, and a valve plate slidably attached to the a plunger that supports the valve body and moves the valve body to a gas cutoff position where it contacts the valve seat and an open position where it separates from the valve seat; and a plunger that is wound around the plunger and presses the valve body toward the valve seat. A magnetic release type magnet device having a biased spring, a permanent magnet that attracts the plunger and normally holds the valve body in an open position separated from the valve seat, and a coil that cancels the magnetic flux of the permanent magnet in response to an abnormal input signal. The gas cutoff device is characterized in that a shape memory alloy that operates due to abnormal temperature is inserted into the magnetic circuit of the permanent magnet, and the magnetic circuit is opened due to the abnormal temperature to release the attraction of the plunger by the permanent magnet. Device. 2 Utility Model Registration Claims The gas cutoff device according to claim 1 is characterized in that a shape memory alloy is attached to the side of the plunger opposite to the valve body, and the contact between the plunger and the yoke is cut off due to abnormal temperature. Shutoff device.
