Description

Technical Field

[0001] The utility model specifically relates to the technical field of gas pipelines, and specifically is a gas pipeline protection device. Background Technique

[0002] Natural gas is a general term for a mixture of hydrocarbon-based gases existing in underground rock reservoirs. Its specific gravity is about 0.65, which is lighter than air, and it is colorless and odorless. Using natural gas as an energy source can reduce the consumption of coal and petroleum, thus greatly improving the environmental pollution problem. Therefore, it is necessary to extract and transport natural gas, and professional natural gas pipelines are used during the transportation of natural gas.

[0003] Chinese Utility Model Publication No. CN 211423704 U discloses a gas pipeline protection device, including a safety protection pipe. The top of the front side of the outer surface of the safety protection pipe is communicated with an inflation valve. The left and right sides of the outer surface of the safety protection pipe are both sleeved with fixed circles. The top of the outer surface of the fixed circle is fixedly connected with a fixed disc, and the bottom of the outer surface of the fixed circle is fixedly connected with a sensor;

[0004] The above-mentioned gas pipeline protection device is made of non-asbestos fiber material for the first sealing layer. Non-asbestos fiber has certain extensibility and elasticity. When the air bag inside is filled with gas and squeezes the first sealing layer, the first sealing layer closely adheres to the gas pipeline, which can effectively improve the sealing effect of the gas pipeline protection device. However, when the pipeline has a long span, due to the action of its own gravity, it is easy to sag in the middle. When it is not supported for a long time, it will deform and cause damage. For this reason, we provide a gas pipeline protection device. Under the action of welding a moving plate or a fixed plate on the guide pipe, the linkage support plate cooperates with the pipeline support plate, the threaded ring cooperates with the moving support plate, and when the auxiliary lead screw drives the threaded ring to rotate, the threaded ring can move, so that the moving support plate cooperates with the linkage support plate to drive the pipeline support plate to move, facilitating the support of pipelines with different diameters and preventing the pipeline from deforming, effectively making up for the above problems.
