[0002] Broadly understood, a pressure pipeline refers to all pipelines that bear internal pressure or external pressure. Regardless of the medium inside the pipe, a pressure pipeline is a part of the pipeline. A pipeline is used to transport, distribute, mix, separate, discharge, measure, control, and stop the flow of fluids. It is an assembly composed of pipes, pipe fittings, flanges, bolt connections, gaskets, valves, other components or pressure-bearing components, and supports;

[0003] After retrieval, the Chinese patent utility model patent with the publication number: CN219870156U discloses a pressure pipeline airtight detection device. This patent records that through a base, both the left and right ends of the upper side of the base are fixed with support seat plates. The connecting seat at the left end is connected with a first pipeline plugging mechanism, and the connecting seat at the right end is connected with a second pipeline plugging mechanism. Both the first pipeline plugging mechanism and the second pipeline plugging mechanism include a moving disk. A rubber pad is fixed on the side of the moving disk away from the connecting seat. A conical guide block is arranged on the side of the rubber pad away from the moving disk. A sealing airbag is arranged between the conical guide block and the rubber pad. This utility model (publication number: CN219870156U) forms a seal by the inflation of the sealing airbag on the first pipeline plugging mechanism and the second pipeline plugging mechanism to contact the inner wall of the pressure pipeline, and the rubber pad tightly abuts against the end of the pressure pipeline to form a second seal, effectively improving the sealing effect and avoiding leakage from affecting the detection result;

[0004] However, the solution with the publication number: CN219870156U has the technical problem of only being able to support pipelines of specific sizes. During the airtight detection process, if the pipeline cannot be firmly clamped, it may shake or displace, resulting in loosening at the detection interface, thus affecting the accuracy of the detection result. And unstable clamping may cause the pipeline to accidentally fall off or rupture during the detection, resulting in leakage of gas or liquid and triggering safety accidents. At the same time, it cannot meet the detection requirements for pipelines of various specifications, restricting the application scope and usage scenarios of the airtight detection device. To solve this technical problem, the present utility model proposes a pressure pipeline airtight detection device. Summary of the Invention

[0027] Working principle: In actual use, the device first needs to place the pipeline to be detected on the opposite side of the two arc-shaped clamping plates 18, and then start the driving motor 2. The driving motor 2 drives the driving rod 3 and the first bevel gear 5, and the rotation of the first bevel gear 5 drives the second bevel gear 6. Through the movement of the second bevel gear 6, the column 7 and the cylindrical gear 9 are driven. The bottom end of the column 7 is rotatably connected to the support ring 8, and the support ring 8 plays a role in supporting and limiting it.

Through the opposite movement of the two arc-shaped clamping plates 18, the stable clamping of the pipeline is realized. The stable clamping can ensure that the pipeline always maintains a good position and state during the detection process, making the detection result more accurate and reliable. And the reliable clamping can effectively reduce the risks such as accidental detachment and rupture of the pipeline, improve the safety of the detection operation, and at the same time can adapt to the detection of pipelines with various diameters, expand the application range of the airtight detection device, and improve the cost performance of the equipment.

One side of the two air storage tanks 23 is fixed on the sliding plate 20. Therefore, the two air storage tanks 23 and the sliding plate 20 slide together on the second guide rail 19. In the middle of the top of the two air storage tanks 23, an air extraction pump 24 is fixedly installed. The output ends of the two air extraction pumps 24 are fixedly installed with a conveying pipeline 25. On the outer diameter of the two conveying pipelines 25, a one-way valve 26 is fixedly installed. The one-way valve 26 plays a role in preventing gas from flowing back.
