摘要： PROBLEM TO BE SOLVED: To provide a gas-blast circuit-breaking device to delay cutoff when a demander uses a gas apparatus when lowering of a battery voltage is detected and a feed of gas is about to stop, and stops the use of the gas apparatus. SOLUTION: When lowering of the voltage of a battery source means 2 is detected by a voltage detecting means 10, a time elapsing after lowering is measured by a time measuring means 12 and after a lapse of a given time, a cutoff signal is outputted but when a flow rate indicating a use is detected, a cutoff signal is delayed by a cutoff signal delay means 16 and when a flow rate stops, a cutoff signal is outputted to stop a feed of gas. This constitution prevents gas from being suddenly cut off during the use of gas and improves facility and safety.

摘要： PROBLEM TO BE SOLVED: To provide a gas shut-off device achieving high gas consumption measuring precision, and providing advantages for cost of gas for users. SOLUTION: As a flow detecting means 19 detects gas flow, it is converted into a flow signal to be outputted, and periods till next output of the flow signal are measured by a period measuring means 20. A period determining means 22 determines if periods measured by the period measuring means 20 is over periods set by a period setting means 21 by a prescribed flow or not. When it is, a time counting means 23 starts counting time. When a time determining means 25 determines that a lower limit time set by a time setting means 24 is exceeded, a flow value converted by a flow converting means 26 is integrated by a flow integration means 27.
