Claims

[Scope of utility model registration request]

An iron piece 17 connected to the valve stem of a valve body 13 is placed opposite to an electromagnet 12 inserted into the electric circuit of the thermocouple, and when the thermoelectromotive force of the thermocouple disappears, the iron piece 17 is released from the electromagnet 12 and the valve body 13 is automatically closed. In a fire extinguishing system for a gas rice cooker equipped with a safety valve 1 of the valve type,
The valve body 13 of the safety valve 1 is inserted into the gas circuit to the burner B, and the valve body 13 is urged in the valve closing direction by the spring 14, and the valve shaft 15 and the iron piece 17 are separated, and the iron piece 17 is also A return biasing force is applied by the spring 18, and the rocking piece 5, which has an engaging portion 51 that engages with the valve body 13 or the valve shaft 15 of the safety valve 1, is attached to the valve body 1.
3 or near the movement locus of the valve stem 15, one end of this swinging piece 5 is used as the engaging part 51, and a magnetic body 52 is attached to the other end, and this swinging piece 5 is attached to the valve body 13 or The swinging piece 5 is set to swing in a direction perpendicular to the movement locus of the valve stem 15, and the swinging piece 5 is housed in the main body 10 of the safety valve 1, and at least the wall surface facing the magnetic material 52 is covered with a non-magnetic material. The output shaft 3 of the heat-sensitive device 3 is attached to the outer surface of the partition wall 16.
A moving rod 6 is provided that moves in conjunction with the partition wall 16 and moves along the partition wall 16, and a permanent magnet 61 is provided on the moving rod 6.
