AI Technical Summary
The electromagnets in existing proportional solenoid valves are large in size, have high input power and heat dissipation problems, and have low output force and low sensitivity, making it difficult to achieve precise position control.
Closed-loop feedback control is adopted. By using the displacement feedback of the pilot valve core and the main valve core, combined with the moving iron electromagnet, the pressure of the hydraulic oil system is used to achieve precise position control of the main valve core. The design incorporates a clearance fit between the pilot valve and the main valve and a floating sliding sleeve structure, and adopts a design with large and small springs linked together.
It achieves precise control of pilot valve flow and precise position adjustment of main valve core. It is small in size, fast in response, has high output force and high sensitivity, avoids jamming during valve core movement, and saves product size.
