The invention discloses a gas leakage-proof system and method and a gas leakage position judging method. The system comprises a centralized control unit, a temperature sensor, a flow sensor, a gas detection alarm, a gas pipeline electromagnetic valve, a gas equipment electromagnetic valve, an extractor hood and an exhaust device. The leakage-proof method includes the following steps that whether gas equipment has flames or not is detected, the gas flow of a gas home-entry main pipeline is detected, whether gas exists in space where gas leakage probably happens is detected, whether gas leakagehappens or not is judged according to the above three factors, and gas supply is cut off if gas leakage happens. The above gas leakage-proof system is used in the gas leakage position judging method for judging. According to the purpose, the gas leakage-proof system and method and the gas leakage position judging method which are safe, practical and capable of preventing gas leakage in time are provided.

Gas leakage-proof system and method and gas leakage position judging method

The utility model discloses a gas safety detection alarm device, including gas alarm, intake pipe and outlet duct, including bee calling organ, automatic control and gas sensor in the gas alarm, install solenoid valve and high accuracy flowmeter in the intake pipe, the outlet duct end is equipped with gas heater and gas -cooker, the outlet duct is established ties through the gas table with the intake pipe, the last switch sensor that installs of gas heater, install temperature sensor on the gas -cooker, switch passes through the wire and is connected with the gas alarm, the utility model discloses a leakage condition of the dual detection gas of gas sensor and high accuracy flowmeter to close the measure that intake pipe and bee calling organ reported to the police through the solenoid valve and remind user gas generation to leak, thereby make the more early counter -measure of making of people, fallled to the loss minimum, improved the security that the gas was used greatly
