Abstract

The pipeline emergency device provided by the invention comprises a first pipeline, a second pipeline, a first pipeline and a second pipeline, the connecting piece is arranged at the end part between the first pipeline and the second pipeline and is suitable for connecting the first pipeline and the second pipeline; the pneumatic switch piece is arranged on the connecting piece and comprises a pneumatic unit and a vibration detection unit which are connected, the vibration detection unit is suitable for detecting external vibration, and the pneumatic unit has a closed state of cutting off the first pipeline and the second pipeline under the action of the vibration detection unit. In the opening state, the first pipeline is communicated with the second pipeline. On-off control over the pipeline is achieved through gas power, it is avoided that electric power is used as driving energy, the reliability and safety of the whole pipeline emergency device are improved, and the defect that in the prior art, in the disaster process of earthquakes and the like, a gas blocking structure of electric power of a gas pipeline has potential safety hazards is effectively overcome.

Description

technical field [0001] The invention relates to the technical field of gas transportation, in particular to a pipeline emergency device. Background technique [0002] Gas pipelines refer to pipelines that are transported from mining sites or processing plants to urban gas distribution centers or industrial enterprise users. The use of gas pipelines to transport natural gas is the only way to transport large quantities of natural gas on land. Gas pipelines are usually a continuous closed delivery system assembled by connecting individual pipes one by one, and the pipelines usually use deep-processed steel pipes. Gas pipeline accidents are very harmful and affect a wide range. Once the pipeline ruptures, it releases a large amount of energy and has a long tear length. If the discharged natural gas encounters an open flame, it is very easy to cause a fire and cause heavy losses. [0003] In order to avoid disasters such as earthquakes, the gas pipeline will be ruptured due t...
