Problems solved by technology
Generally, medium and high pressure direct-acting and hydraulic damping solenoid valves are not reliable in action and sealing under ultra-high pressure conditions. At present, the on-off valves used in ultra-high pressure water hydraulic systems are mainly electric ball valves, and electric ball valves have reactions. Too slow, unable to self-reset and close, too long open time and the need for multi-channel electrical signal control, etc., severely limit the application of ultra-high voltage systems

An ultra-high-pressure anti-pollution type water hydraulic electro-hydraulic switch valve comprises a valve body (1), an emergency push rod (4), a base (5), a valve seat (9), a main valve element (11), a main spring (12), a damping ring (13), a control valve plate (14), a pilot valve body (15) and a valve opening and closing device; and the valve opening and closing device comprises a right pilot valve seat (6), a right push rod (7), a torque lever (8), a left pilot valve seat (16), a pilot valve spring (17), a left push rod (18), a valve bush, a ceramic ball valve element (20) and an electromagnet (22). The ultra-high-pressure anti-pollution type water hydraulic electro-hydraulic switch valve has the technical effect that by the structural style of an electromagnetic valve, prominent problems that the electric valve responds slowly and a system is controlled complicatedly are avoided, meanwhile, by the torque lever, an electromagnetic force is amplified to adapt to the working condition of ultra-high pressure, and therefore, valve opening reliability is improved.
Description
technical field [0001] An ultra-high pressure anti-pollution water-hydraulic electro-hydraulic switch valve Background technique [0002] In the water hydraulic transmission and control system, the water hydraulic system with a system pressure greater than 31.5MPa is generally called an ultra-high pressure system. The ultra-high pressure water hydraulic system is mainly used in water jet cutting and cleaning, deep sea exploration engineering, coal machinery and other fields. Compared with mineral oil, water has a big difference in physical and chemical properties, such as the viscosity of water is small, the viscosity coefficient is small, which increases the difficulty of sealing and lubrication, the pressure level of water hydraulic components on the market is mainly less than 21MPa At medium and high pressure. [0003] Under ultra-high pressure conditions, component design has higher requirements for action and sealing reliability, and anti-pollution capabilities. Gene...
