The hydraulic support is the core equipment in the fully mechanized coal mining face support system, which is used to support the roof of coal roadway to prevent the coal gangue from falling and maximum protection of personnel and equipment safety. Valves are the main control components in the hydraulic support, include relef valve, reversing valve, pilot-operated check valve, shut-off valve. The performance of the valve components directly affects the working condition of the hydraulic support. The study on valve components performance test methods and system has important practical significance for coal mine production. In this paper, according to the national standard GB25794.3-2010《coal mine hydraulic support part 3: hydraulic control system and valve》requirements for the hydraulic support valve components performance testing , Study identified the valve components performance test system needs to complete the test project and the main detection parameters. According to the modular design the valve component performance test hydraulic circuit, then complete hydraulic test bench key components parameter calculation and component selection.
