Device of ability self -closing coal gas leather hose valve during gas leakage

The utility model discloses a device of ability self -closing coal gas leather hose valve during gas leakage. When the pipeline leads to gas leakage because of corrosion or other reasons, may be to people's the person and the very big potential safety hazard of property safety constitution. The utility model provides a device of ability self -closing coal gas leather hose valve during gas leakage, when gas leakage, leakage that gas flowmeter can automated inspection coal gas, valve in the self -closing coal gas leather hose. Technical scheme is: the utility model discloses a gas outlet of gas bottle body is connected with the relief pressure valve, and solenoid valve one side is connected with the gas outlet of relief pressure valve, and the solenoid valve opposite side passes through the leather hose to be connected with gas flowmeter, and the gas flowmeter other end is connected with the gas range, is equipped with the air supply switch on the gas range. When gas leakage, leakage that gas flowmeter can automated inspection coal gas, the solenoid valve of control system in can self -closing coal gas leather hose to prevent the potential safety hazard that gas leakage brought.
