Description

Technical Field

[0001] The utility model relates to the technical field of pressure pipeline detection, and particularly relates to an auxiliary device for pressure pipeline detection. Background Art

[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 a pipeline. A pipeline is an assembly composed of pipes, pipe fittings, flanges, bolt connections, gaskets, valves, other components or pressure-bearing components and supports for transporting, distributing, mixing, separating, discharging, metering, controlling, and stopping the flow of fluids. When in use, a pressure pipeline not only has certain requirements for pressure but also needs to meet certain requirements for sealing. Due to the large volume of the pipeline, it is difficult to detect the sealing performance of the pressure pipeline, and generally, a large amount of water source will be wasted during detection, resulting in waste of resources. Therefore, it is necessary to improve the existing device to meet the actual needs.

[0003] Publication No. CN220018841U discloses an auxiliary device for pressure pipeline detection, including a detection table. A placement plate is installed on the upper surface of the detection table, and a support frame is installed on one side of the upper surface. A detection pipeline is installed at the top of the placement plate. A driving motor is installed on the side of the support frame, and a movable groove is opened inside. A positive and negative thread lead screw is installed at the axis of the driving motor. A moving block is installed on the outer peripheral surface of the positive and negative thread lead screw. A plug block is installed at the bottom of the moving block, and a plug head is installed on the side of the plug block. A water tank is installed on one side of the upper surface of the detection table. A first water pump is installed on one side of the water tank, and a second water pump is installed on the other side.

[0004] In order to solve the problem of wasting a large amount of water source during the detection of the sealing performance of the pressure pipeline, the prior art is to use a water pump to pump the water in the pipe back to the water tank for treatment. However, there will still be a situation where pipes of different sizes cannot be fixed, resulting in a small application range of the device. Summary of the Utility Model
