Abstract
PURPOSE: To prevent a gas accident due to defects within a gas supply system by a constant and automatic inspection of the gas supply system.
CONSTITUTION: When the gas is not used, an operation switch 10 is in an opened- state so as not to output a signal. As a result, a solenoid valve 2 is closed, so that a gas accident never occurs in the downstream of the solenoid valve 2. To the contrary, when the gas is used, the operation switch 10 is turned ON to output a signal to a control board 20. The control board 20 then permits a power supply to the solenoid valve 2, thereby putting the gas implement into an operable condition. It should be noted that the selenoid valve 2 is closed for a predetermined period of time after it is once opened. During this closing period of the solenoid valve 2, if the gas pressure falls due to an accident such as a hose disconnection or an improper piping and the solenoid valve 2 receives a signal repressenting the gas pressure fall, the solenoid valve 2 is electrically locked in the closed-state through a prohibition circuit 25 and issues an alarm.
