Natural gas security protection equipment by filling gas bag through leaked gas and cutting off gas supply and power source

Abstract

The invention discloses natural gas security protection equipment by filling gas bag through leaked gas and cutting off gas supply and a power source. The natural gas security protection equipment structurally comprises a security protection apparatus, a shell, a protruding cover and a through hole; the security protection apparatus is mounted in the shell and fixedly connected with the shell; theprotruding cover is mounted at the top of the outer wall of the shell; the shell is mechanically welded to the protruding cover; the through hole is formed in the protruding cover; and the through hole penetrates through the protruding cover. The natural gas security protection equipment has the beneficial effects that the gas bag is filled with leaked natural gas and expanded, a protruding rod and a groove rod are pushed to be matched with each other in an embedded mode, an outlet pipe between the protruding rod and the groove rod is clamped, thus the outlet pipe is in a closed state, thus supply of natural gas is cut off, under push after gas bag expanding, two electric conductive rods rotate, then electric conductive blocks are separated from fixed electric conductive blocks, thus communication between wire incoming and wire outcoming is cut off, the power source is cut off, and the using security coefficient of natural gas is improved.

Description

technical field [0001] The invention relates to the field of security devices, in particular to a natural gas security device that uses air leakage to fill an air bag and cuts off gas supply and power supply. Background technique [0002] The main use of natural gas is as a fuel, and it is widely used in household applications. However, the use of natural gas requires high gas tightness detection. In order to improve the safety of natural gas in household applications, the airtightness of natural gas is required. For real-time monitoring, the current security devices for natural gas applications have the following defects: [0003] Natural gas is flammable and requires high airtightness in hot weather during use. Natural gas is transported indoors through pipelines. Under factors such as indoor pipeline corruption, natural gas will leak. Traditional natural gas security devices are monitored. When natural gas leaks, only an alarm will be issued, but the power supply cannot ...

[0003] Natural gas is flammable and requires high airtightness in hot weather during use. Natural gas is transported indoors through pipelines. Under factors such as indoor pipeline corruption, natural gas will leak. Traditional natural gas security devices are monitored. When natural gas leaks, only an alarm will be issued, but the power supply cannot be cut off in time, posing a major safety hazard
