When detected, the time measurement is started by the time measurement means, and the battery warning expiration means first outputs the battery expiration date abnormality, the alarm means displays the abnormality, and notifies the consumer of the battery voltage abnormality, thereby shutting off the gas. It is possible to notify the necessity of replacing the device, and even if the gas company or the like inadvertently forgets the replacement, the gas measuring device 14 shuts off the gas after a predetermined time elapses, and shuts off the gas so that it cannot be used again. It strongly encourages customers to exchange. Even if the battery expiration date has passed, it is possible to eliminate a problem that the battery voltage is lowered due to a sudden drop in the temperature in winter and the warning is displayed, and the battery cannot be shut off after a predetermined period. For example, when using gas appliances at the customer's house after the expiration of the battery expiration date, when using a heating device such as a gas stove in the winter, when the battery expiration date has passed much when a sudden temperature drop occurs due to cold waves etc. However, since the degree of consumption of the battery voltage drops sharply as compared with the case where the battery capacity is sufficient, it is necessary to shut off the usage time when using a gas stove or the like for an abnormally long time, but it cannot be shut off due to battery exhaustion. The gas consumer can use the gas appliance with peace of mind, and the time measuring means counts the elapsed time after the battery has dropped, and if the gas shut-off device is not replaced for any reason during that time, the battery voltage It is dangerous to continuously monitor the use condition of gas appliances because it is expected to decrease due to further wear of the gas appliance. At the same time, the safety monitoring function due to the depletion of the battery power supply operates normally by prohibiting the return acceptance of the shut-off means for gas supply and maintaining the shut-off state so that the consumer cannot use the gas appliance by mistake. It is prevented from disappearing, and safety and reliability are improved.

Since the battery power supply has started to be supplied, the battery usage time is measured by the battery usage time measurement means 10 and the voltage warning determination means 12 determines whether the usage time set in the battery usage time setting means 11 has been reached.
When the battery usage time elapse is detected, it is determined that the battery usage time elapses abnormally, and the gas consumer and gas supply company are immediately notified of the battery usage period elapse abnormality. Even if you were using gas appliances,
For example, if a heating device such as a gas stove is used, if it is suddenly shut off, the gas valve of the gas stove must be closed once and gas must be supplied by operating the return means 14 to use gas again. If it is returned with the plug closed, raw gas will be discharged, which may cause gas poisoning, trouble such as CO gas leakage, or fire due to the worst gas. Trouble due to interruption during use can be prevented.

保持する。After that, even if the gas expiration date has passed and the gas shut-off device is continuously used without being replaced, the gas flow detecting means 17 detects the gas while the time measuring means 13 is counting for a predetermined time. When an abnormal use condition of the appliance is detected, when a gas leak or a CO leak is detected by the external device means 18, or when a strong earthquake is detected by the seismic sensor, the shut-off means 3 is driven to stop the gas supply. Then, the counting of the time measurement unit time 13 is stopped, and the shutoff signal is notified to the return prohibition unit 15 to prohibit the return so that the gas cannot be used again. In such a case, when the shut-off means 3 is driven, a large amount of the capacity of the battery power is consumed, so that it becomes difficult to accurately monitor the use state of the gas appliance. The opening operation of the shutoff means 3 is prohibited via the return means 14 and the cutoff state is maintained.

態になる可能性が高い。Therefore, it is possible to prevent the safety monitoring from being performed normally when the battery has expired. In particular, if the gas shut-off device is not replaced and the battery is consumed so that most of the battery capacity is consumed, especially in the winter, the sudden increase occurs. When a low temperature condition occurs, if the gas hose of a gas appliance detects an abnormal use condition such as a disconnection, the total flow rate will be cut off.However, if the battery capacity is at the end of its life, the voltage may drop sharply and the worst case may occur. Is high.

Since the expiration date is set, it will not be in an unblockable state, and even if you warn you of the battery expiration date, you will be used abnormally many times afterwards, and abnormal battery consumption will be caused. In such a case, it is shut off immediately upon occurrence of a shut-off event due to abnormality detection, so that it cannot be returned again and the replacement of the gas shut-off device is promoted, so that safety and usability are greatly improved.
