[0002] A hydraulic valve is an automatic component operated by pressure oil. It is controlled by the pressure oil of a pressure regulating valve and is usually used in combination with an electromagnetic pressure regulating valve. It can be used to remotely control the on / off of the oil, gas, and water pipeline systems of a hydropower station. Before the hydraulic valve is put into use, it is necessary to conduct a series of quality tests on the hydraulic valve, such as strength test and air tightness test. When conducting air tightness tests on hydraulic valves, different models of products often have different numbers of outlets. When conducting air tightness tests on hydraulic valves, it is often necessary to replace different equipment to complete the tests.
