Claims

[Claims for Utility Model Registration] (1) A solenoid valve, a thermocouple, and a controller that detects the thermoelectromotive force of the thermocouple and controls the opening and closing of the solenoid valve based on the detection signal, and A solenoid valve is disposed between the gas meter pot and the indoor gas pot in a gas supply path that supplies gas to the gas appliance via the two pots, and the thermocouple is disposed at a position close to the burner portion of the gas appliance. , the controller detects the thermoelectromotive force of the thermocouple according to the temperature of the burner section of the gas appliance, and automatically closes the solenoid valve when the detected thermoelectromotive force falls below a predetermined value. A gas leak prevention device characterized by: (2) The gas leak prevention device according to claim 1, wherein the controller is provided with a switch or a timer for opening the solenoid valve only for a predetermined time regardless of the value of the electromotive force detected by the thermocouple.
