Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection technology, specifically to an automatic pipeline sealing pressure testing device. Background Technology

[0002] Pipelines are devices made up of pipes, pipe fittings, valves, etc., used to transport gases, liquids, or fluids containing solid particles. Sealing tests are used to check whether the pipes are properly sealed and whether there is any damage. Typical sealing test devices are large, difficult to move, and inconvenient to replace in different locations.

[0003] CN219956806U discloses a pipe sealing testing device, including a testing chamber. Slide seats are slidably mounted on the inner walls of the front and rear ends of the testing chamber via connecting components. Bolts are threaded onto the inner side of the bottom of the rear slide seat. The four corners of the two testing chambers are fixedly connected by connecting plates. The slide seats, fixed sleeves, and fixed seats facilitate the device's operation. During use, the two slide seats can be moved out of the testing chamber under the limiting action of the sliding groove and slider. One end of the pipe is then fitted onto the outside of the fixed sleeve, and the other end of the pipe is placed on top of the support sleeve. A movable block supports the other end of the pipe, thus achieving a seal at both ends of the pipe. This application uses a convex spring to fix both ends of the pipe, but this method is only suitable for testing fixed-size water pipes due to varying pipe lengths and sizes. Furthermore, testing by immersing the pipe in water and using air bubbles makes it difficult or impossible to observe minor damage. Therefore, an automatic pipe sealing pressure testing device is proposed. Utility Model Content
