A monitoring alarm and interlocking device for bursting of trunk pipelines in distribution stations of gas pipelines

Abstract

The invention discloses an interlocking device for monitoring and alarming the explosion of a main line pipeline of a distribution station of a gas transmission pipeline. The device comprises: connection; the first pressure transmission and the second pressure transmission are arranged in parallel, one end of the first pressure transmission and the second pressure transmission are connected with the upstream section of the first bypass line, and the other ends are connected with the controller; the third pressure transmission and The fourth pressure transmission is arranged in parallel, one end of the third pressure transmission and the fourth pressure transmission are both connected to the downstream section of the first bypass line, and the other ends are connected to the controller. The beneficial effects of the present invention are as follows: the monitoring and alarming speed of pipeline explosion is more timely and the accuracy rate is higher, and the safety of personnel and property in the gas transmission pipeline and surrounding areas is improved; Gas pipe burst monitoring tends to be more practical, reducing equipment investment and construction costs.

Description

technical field [0001] The invention relates to the technical field of gas transmission pipeline systems, in particular to a monitoring, alarm and interlocking device for bursting of a trunk pipeline of a distribution station of a gas transmission pipeline. Background technique [0002] During the operation of the pipeline, due to pipeline corrosion, third-party damage, construction quality and other reasons, the natural gas pipeline ruptures or breaks, resulting in natural gas leakage, which eventually brews into an oil and gas pipeline safety accident, causing great adverse effects on society and enterprises. It has also brought a serious threat to the safety of life and property of the people around the pipeline. If the relevant information such as whether the pipeline is broken or broken is not grasped in time and dealt with in time, the consequences of the accident will continue to increase, causing serious environmental pollution and significant personal and property l...

Problems solved by technology

[0002] During the operation of the pipeline, due to pipeline corrosion, third-party damage, construction quality and other reasons, the natural gas pipeline ruptures or breaks, resulting in natural gas leakage, which eventually brews into an oil and gas pipeline safety accident, causing great adverse effects on society and enterprises. It also poses a serious threat to the life and property safety of the people around the pipeline.

If the relevant information such as whether the pipeline is broken or broken is not grasped in time and dealt with in a timely manner, the consequences of the accident will continue to increase, causing serious environmental pollution and major personal and property losses.

[0003] For gas pipeline leakage caused by pipeline corrosion, third-party damage, construction quality, etc., since natural gas is a compressible fluid, previous projects could not use the oil pipeline method for leakage monitoring, and it was impossible to realize emergency shutdown of the transmission system in case of abnormal conditions The emergency shutdown function of entering and exiting stations, so that only when there are major accidents such as natural gas leakage, fire or explosion that can be observed by human eyes, relevant problems can be found
