Abstract：

The working principle of the electromagnetic unloading relief valve was expounded, and the mathematical models of its automatic unloading and loading processes were established. Then, the influence factors of its opening and closing performance were studied. Furthermore, a simulation model was built based on AMESim, and the influences of the diameter of the control piston and the diameter of cone valve of pilot valve inlet on the opening and closing performance were analyzed by simulation. At last, the experimental research was conducted, and the results show that the opening and closing performance of the electromagnetic unloading relief valve depends mainly on the diameter of the control piston and the diameter of cone valve of pilot valve inlet. The diameter of control piston mainly affects the loading pressure of electromagnetic unloading relief valve, while the loading pressure largely depends on the diameter of cone valve of pilot valve inlet. Therefore, they have combined effects on the switching pressure difference of the electromagnetic unloading relief valve.
