Abstract
PURPOSE: To provide a gas leak warning and gas supply shut-off system which surely and safely prevents explosion, fire or the like due to gas leakage, by connecting a warning buzzer switch and valve open/close solenoids to each other.
CONSTITUTION: A gas leak warning unit 1, which contains a semiconductor gas reactor which reacts when organic gas reaches a prescribed concentration, is provided in a prescribed position. The warning buzzer switch 2 of the unit 1 and the valve open/close solenoids 4, 5 of a casing 3 are connected to each other through a control panel 8 equipped with switches 6, 7. A reciprocating slide shaft 9 for the solenoid 4 and a diaphragm 11 made of an elastic material for a gas open/close valve 10 are coupled to each other by an insulated flexible wire 12 of prescribed length. The casing 3 and the gas open/close valve 10 are connected to each other through an insulated flexible pipe 13 in which the flexible wire 12 is laid. The diaphragm 11 is moved upward and downward to open or close the gas valve 10.
