Abstract
PURPOSE: To momentarily stop gas supply at the same time as occurrence of a fire and avoid generation of a secondary disaster by furnishing a valve case with a gas shutoff valve which is actuated with drop of the inner pressure when a fire extinguishing agent is sprayed. CONSTITUTION: A sensing nozzle 23 of a fire extinguishin agent supply hose 6 flexible is dxomgomg rddires to a gas stove 21, and its gas pipe is connected with an automatic extinction device. When the nozzle 23 senses a fire, the tip is opened.to spray a fire extinguishing agent, so that the internal pressure of the body 1 of extinguisher pr reduces. Thereby a diaphragm 8 is moved toward the extinguisher body l by the repulsive force of a push spring 16 installed on a slide bar 15, and at the same time, a valve stem 14 moves toward a gas outlet 18 to close the gas flow passage 13, and thereby the gas supply to the gas stove is stopped. There is no risk that gas is spouting when the fire goes out, and hazard of gas explosion, etc., can be avoided.
