ものである。Means for Solving the Problems In order to achieve the above object, the gas cutoff device of the present invention includes a flow rate sensor that detects the gas flow rate from a gas meter, and a consumption rate of each gas appliance connected to the end of the gas meter. a storage device that stores the gas flow rate through the flow rate sensor, and a registration switch used to store and register the gas flow rate in the storage device;
A logical determination circuit that compares the registered value in the storage device with a constant flow rate value from a gas meter to determine an abnormality in the gas flow rate, and a shutoff valve that shuts off when the logical determination circuit determines that the flow rate is abnormal. It is structured as follows.
作 用
この構成により、先づガスメータの先に接続さ

ツチで記憶装置に個々に登録し、そののちは流量
センサで常時流量を監視し、個々の流量と違う大
流量がある場合に論理回路で異常と判断し、遮断
弁を駆動してガス通路を遮断する。Effect With this configuration, the actual gas consumption of the gas appliances connected to the end of the gas meter is first registered individually in the storage device using the registration switch, and then the flow rate is constantly monitored using the flow rate sensor, and each If there is a large flow rate that is different from the flow rate, the logic circuit determines that there is an abnormality and drives the shutoff valve to shut off the gas passage.

もとより誤遮断も防ぐことができる。Embodiment An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of one embodiment of the present invention. In Fig. 1, 1 is a gas cutoff device, 2 is a microcomputer (hereinafter referred to as microcomputer), 3 is a cutoff valve, 4 is a gas meter, and 5 is a gas cutoff device.
is a flow rate sensor attached to the gas meter 4, 6 is a logic judgment circuit of the microcomputer 2, 7 is a storage device (hereinafter referred to as RAM) of the microcomputer 2, 8 is a registration switch,
Reference numeral 9 indicates a plurality of gas appliances attached to the end of the gas meter 4. Gas cutoff device 1 or gas meter 4
At the time of installation, the registration switch 8 is turned on to actually operate each gas appliance 9, and the respective gas flow rates at that time are registered in the RAM 7 of the microcomputer 2. When the registration is completed, the registration switch 8 is turned off. After this, the usage status of the flow rate sensor 5 and the gas appliance 9 is constantly sent to the microcomputer 2 and constantly compared with the flow rate registered in the RAM 7. If the flow rate is larger than the flow rate registered in RAM7, the logic judgment circuit 6 of the microcomputer 2 determines that there is an abnormality, and the microcomputer 2
drives the shutoff valve 3 to stop the gas supply. This makes it possible to make decisions based on the gas consumption pattern suited to each household, and prevent gas accidents as well as erroneous shutoffs.
