Description

Technical Field

[0001] The present application relates to the field of pipeline detection, and in particular to a safety pressure testing device for a long-distance natural gas pipeline. Background Art

[0002] A natural gas pipeline is a pipeline that transports natural gas from the mining site or processing plant to the urban gas distribution center or industrial enterprise user, also known as a gas transmission pipeline. Using a natural gas pipeline to transport natural gas is a way to transport natural gas in large quantities on land. Natural gas pipelines account for about half of the total length of pipelines in the world. 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, small transportation loss, no three wastes, small risk of leakage, small pollution to the environment, small impact of bad weather, small equipment maintenance, easy management, and easy remote centralized monitoring. At present, long-distance natural gas pipelines must be pressure tested before use.

[0003] A pipeline gas pressure testing device provided by the publication number "CN220729894U" aims at solving the problems that when the existing pressure testing pipeline is pressure tested, it needs to be welded to one end of the pressure testing short tube, and disassembly and installation are very cumbersome, time-consuming and labor-intensive. It can only be pressure tested for pipelines of one size, has a small scope of application and is inconvenient to use. The following scheme is now proposed, which includes a bottom plate, a pad is fixedly connected to the top of the bottom plate, a third fixed plate is fixedly connected to the top of the pad, a third sliding plate is slidably connected to one side of the third fixed plate, and the pressure testing short tube is fixedly connected to one side of the third sliding plate. In the utility model, an arc-shaped sheet is provided, which can be used to fix the pressure testing pipeline, and at the same time, the center position of the pressure testing short tube can be determined according to the indication of the second pointer and the first scale line to ensure the test effect. By turning the hand wheel, the height of the pressure testing short tube can be adjusted to align with the center of the pressure testing pipeline, which is convenient for subsequent plug-in.

[0004] The existing natural gas long-distance pipeline safety pressure test device still has the problem of being inconvenient to fix pipelines of different specifications when in use. Manual operation is required when fixing the pipeline, and the pipeline cannot be automatically and effectively fixed. At the same time, it has no buffer protection function and cannot provide buffer protection for the pipeline when clamping and fixing. It is easy to cause damage to the pipeline when clamping and fixing. In serious cases, it will bring safety hazards during pressure testing, which is not conducive to use. Utility Model Content
