Description

Technical Field

[0001] The utility model relates to the technical field of centering for pipeline pressure detection, in particular to a centering device for pipeline pressure detection. Background Art

[0002] Pressure pipelines refer to all pipelines that are subject to internal or external pressure. Since pressure pipelines need to withstand pressure, the inside of the pressure pipelines needs to be inspected after production to ensure that the pressure pipelines are qualified products. A centering device for pipeline pressure testing is often used during the testing process.

[0003] According to the description of a pressure detection device for a pressure pipeline disclosed on the patent website (authorization announcement number: CN213337126U), "The present application discloses a pressure detection device for a pressure pipeline, including a fixed ring, a through hole is fixedly provided on the top of the fixed ring, the inner wall of the fixed ring is fixedly connected to an annular groove, the annular groove is slidably connected to a sliding rod, the inner wall of the fixed ring is fixedly connected to one end of a first connecting column, the other end of the first connecting column is slidably sleeved on one end of a second connecting column, the other end of the second connecting column is fixedly connected to the center of the side wall of the connecting plate, the first connecting column and the second connecting column are covered with a second spring, and one end of the second spring is fixedly connected to the inner wall of the fixed ring. Through the provision of the third connecting column, the pipeline fixing plate can be adjusted according to pressure pipelines of different diameters, thereby fixing the entire device at the position required for detection, and by slidingly sleeved the first connecting column and the second connecting column, the pressure pipeline is further fixed under the action of the spring, thereby further increasing the flexibility of the entire device."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use, the utility model can adjust the pipe fixing plate according to pressure pipes of different diameters through the third connecting column, thereby fixing the entire device at the position required for detection, and further fix the pressure pipe under the action of the spring by sliding the first connecting column and the second connecting column. However, in actual application, the device only clamps and centers the pipe through the spring, which can easily cause the pipe to shift when operating the detection equipment, resulting in inaccurate detection results. In addition, the detection mechanism of the device is relatively fixed in position, making it difficult to quickly detect different positions of the pipe without changing the clamping state. Therefore, we urgently need to improve a centering device for pipe pressure detection to solve the above problems. Utility Model Content
