Abstract

The invention discloses a sealing device for a natural gas pipeline, and relates to the technical field of natural gas pipeline parts. The sealing device comprises a fixing rod and an anti-tripping buckle, wherein the top end and the bottom end of the fixing rod are fixedly connected with the middle of the surface of the anti-tripping buckle, and a connecting pipe and a fixing pipe penetrate through the middle of the top and the middle of the bottom of the surface of a connecting box correspondingly; and the top of the surface of the fixing rod is fixedly connected with a fixing plate througha rotating shaft, wherein a rotating piece penetrates through the middle of the right side of the surface of the fixing plate. According to the sealing device for the natural gas pipeline, an emergency protection function is provided, so when natural gas leakage occurs, autonomous treatment can be carried out at the first time, so that losses caused by the natural gas leakage are reduced, in thisway, people can maintain the sealing device conveniently in the follow-up process, and meanwhile the cost can be greatly reduced; and moreover, the emission of leaked natural gas is reduced, so that no pollution is caused to air, surrounding residents feel safer, and use is facilitated for the people.

Description

technical field [0001] The invention relates to the technical field of natural gas pipeline components, in particular to a sealing device for natural gas pipelines. Background technique [0002] Natural gas pipelines refer to the pipelines that transport natural gas (including associated gas produced in oil fields) from mining sites or processing plants to urban gas distribution centers or industrial enterprise users, also known as gas pipelines. Natural gas pipelines are used to transport natural gas. Gas way. Natural gas pipelines account for about half of the world's total pipeline length. Natural gas pipeline transportation has the advantages of low transportation cost, small land occupation, fast construction, large oil and gas transportation volume, high safety performance, low transportation loss, no "three wastes" emissions, and low risk of leakage , less environmental pollution, less affected by harsh weather, less equipment maintenance, easy to manage, easy to rea...
