[0002] During the manufacturing process of pressure vessels, a water pressure test device is generally used to perform a pressure test on the pressure vessel to test whether the pressure resistance performance of the pressure vessel meets the standard. When the existing pressure vessels are tested with a water pressure test device, since the pressure test of the container has strict requirements on the ambient temperature, if the outside temperature is low, the container is easily affected by the low temperature and the container is prone to lose its original hardness, which makes it easy to explode during the pressure test. Therefore, during the water pressure test of the existing container, the container is placed inside a protective device. However, the existing pressure vessels have different sizes and lengths, and the water pressure test protective components cannot be stored in different containers, resulting in limited and single practicality. For this reason, we propose a water pressure test device for pressure vessels. Utility Model Content
