Abstract

PURPOSE: To prevent gas accidents securely by a combination of an electric detection of the open or closed state of an implement plug or a remaining gas pressure and an electric detection of the existence of combustion.
CONSTITUTION: In the vicinity of a gas source in a pipe 7, there is provided a self-retaining breaker valve 3 which opens and closes in response to a signal from a controller main unit 4, and in the downstream of the valve 3 is arranged a pressure detecting part 5. The respective gas implement connected to the pipe 7 is provided with a switch openable in association with the opening of the implement plug and an oxygen-lacked condition detecting part which detects an abnormal combustion from a change in an electric signal from a combustion responsive electrode. These switch and combustion responsive elecctrode provide an electric signal representing whether the implement plug is opened or not and another electric signal representing whether the combustion is normal or not when the implement plug is open. Thus provided signals are inputted into the controller main unit 4 and combined therein. The controller main unit 4 then outputs a control signal to control a power supply passage to the breaker valve 3 to open or close.
