Abstract
PURPOSE:To operate a cutoff valve only at the time of danger and to take a proper measure, knowing how gas is used without operating the cutoff valve in the other cases by sending signals of gas use conditions to a control center to be input to a computer. CONSTITUTION:Signals of a gas checking meter N1, a reset switch N2 and a gas leakage sensor N3 are input to a gas safety device A to be sent to a computer of a control center through a telephone line L. When preset conditions are satisfied, the computer is adapted to operate according to the conditions. When the quantity of gas used exceeds the preset flow, a cutoff signal is generated to operate a cutoff valve N4, and when it exceeds the maximum change flow, instantaneously the cutoff valve N4 is not operated, but the state is informed. Accordingly, at the time of danger, the cutoff valve N4 is operated, and at the time of low risk, a proper measure can be taken without operating the cutoff valve.
