AI Technical Summary
Traditional hydraulic valves are prone to internal fluid accumulation when closed, which can lead to component rust and reduced lubrication performance, thus affecting their service life.
A hydraulic valve body anti-liquid accumulation structure was designed, which includes a drainage mechanism and a deceleration mechanism. The valve core is moved by the solenoid valve rod, and the accumulated liquid is discharged by the combination of the compression spring and the piston block with the liquid guide hole and the liquid outlet hole. The movement of the piston ring is buffered by the deceleration mechanism to prevent liquid from flowing out.
It effectively drains accumulated fluid from inside the valve body, preventing rust and wear, and extending the service life of the hydraulic valve.
