Therefore, leak detection is required during the production and use of pressure vessels.

However, water needs to be added before each test, resulting in a waste of time and water resources.

[0005] Therefore, it is necessary to provide a pressure vessel leakage detection device to solve the above technical problems. Utility Model Content
