[0002] At present, during the production process of PVC plastic pipes, it is necessary to conduct a water pressure test on the pipes. Generally, two pipes are glued together with glue, and the pressure test is carried out after curing. The seals are installed at both ends of the pipes, and the pressure is slowly increased using a manual pump or an electric pump. After the pressure reaches the specified test pressure, the pressure is stabilized and observed to see if there is any leakage.

At the same time, after the pipe is filled with water, it is not easy for one person to move it.

[0004] Therefore, it is urgent to develop a test device that can assist work personnel in conducting water pressure tests. Utility Model Content

[0026] The implementation principle of a water pressure test device for plastic pipe production in the embodiment of the present application is as follows:
