記載のガス供給路遮断システム。[Scope of claim for utility model registration] (1) A gas meter with a built-in shutoff valve that operates using a battery as a power source is installed in the gas supply path, and a gas leak alarm is installed in the gas use room, and the gas leak alarm detects gas leaks. In a gas supply path cutoff system in which a signal is given as a cutoff valve operation signal of the gas meter with a built-in cutoff valve via a transmission line, the gas leak alarm sends a signal of voltage V 1 during normal times, and the signal of voltage V 1 when a gas leak is detected. 1 , the gas meter with a built-in shutoff valve includes a secondary battery as the battery, and a circuit that charges the secondary battery with the output of the gas leak alarm; A gas supply path cutoff system comprising a circuit that operates the cutoff valve when the voltage V2 is output from the gas leak alarm. (2) The gas meter with a built-in shutoff valve includes a circuit that converts voltage signals of different levels output from the gas leak alarm into light intensity signals, and a circuit that converts the output light of this circuit into a voltage level signal. A gas supply path cutoff system according to claim 1, characterized in that the system comprises: (3) The gas supply line cutoff system according to claim 2, wherein the circuit for converting the optical signal into a voltage level signal is mainly composed of a solar cell. (4) The utility model registration claim 1 is characterized in that the gas meter with a built-in shutoff valve includes a circuit that introduces voltage signals of different levels output from the gas leak alarm via an isolation transformer. The gas supply path cutoff system according to item 1.
