[0002] During the production of pipe fittings and pipes, in order to ensure their normal use and service life in the pipeline system in the future, the pipe fittings and pipes need to be pressure tested. Pressure testing refers to the process of testing the pressure resistance of pipe fittings and pipes, and this process requires pressure testing instruments.

[0003] For example, an intelligent pressure tester for pipe fittings and pipes with publication number CN210982062U sets a water tank and a heating rod in the water tank, controls the water temperature in the water tank through the heating rod, injects water of different temperatures into the pipe, and then uses a pressure plate to pressurize the pipe to test its pressure resistance, which is helpful for detecting the impact of fluids of different temperatures on pipe fittings. However, when testing, the two ends of the pipe need to be placed against two plugging heads respectively, but the positions of the two plugging heads are fixed, and it is not easy to place a pipe of fixed length between the plugging heads, which will reduce the detection efficiency. For this reason, an intelligent pressure tester is proposed for improvement. Utility Model Content
