Natural gas anti-leakage closing device

Abstract

Disclosed is a natural gas anti-leakage closing device. The natural gas anti-leakage closing device comprises a gas tank (1), and a tank opening valve body (3) is mounted on an upper end port of the gas tank (1). The natural gas anti-leakage closing device is characterized in that an electromagnetic valve (4) is mounted at the gas outlet end of the tank opening valve body (3); a control channel inside the electromagnetic valve (4) is connected with one end of a gas delivery hose (5); an electromagnetic opening-closing device is arranged in the control channel inside the electromagnetic valve (4); the electromagnetic valve (4) is connected with the output end of a control module (8); and the input end of the control module (8) is connected with flame detectors (7) through signal lines (9). According to the natural gas anti-leakage closing device, the electromagnetic valve is mounted at the gas outlet end of the tank opening valve body, the flame detectors are mounted outside flame jet rings on a gas stove (2), and the electromagnetic valve and the flame detectors are connected with the control module; the electromagnetic valve is controlled through the control module so as to open or close a gas supply opening of the gas tank, occurrence of gas poisoning or fire accidents is avoided, and the safety performance is greatly improved.

Description

technical field [0001] The invention relates to an anti-leakage closing device, in particular to an anti-leakage closing device for natural gas, which belongs to the technical field of household appliances. Background technique [0002] At present, most of the natural gas pipelines used by people are simple in structure and do not have the function of automatically shutting off the gas. In actual use, if the soup in the pot on the gas stove overflows, the fire will be poured out. At the same time, the strong wind may also blow out the fire. . If the furnace fire goes out accidentally, it will easily cause gas poisoning or fire accidents caused by the continuous transportation of gas, which will pose a great potential safety hazard. Contents of the invention [0003] The purpose of the present invention is to solve the defects and deficiencies of the currently used gas tanks, which are simple in structure, do not have the function of automatically shutting off the natural ...
