比例电磁铁在插装电磁阀上的应用

介绍一种新型插装式电磁阀,它采用二级控制,将先导阀和主阀芯集成在一起,组成一个插装件。与传统的插装式电磁阀相比,该电磁阀的电磁铁采用比例电磁铁,根据电磁吸力与弹簧力的平衡调节先导阀的启闭,使主阀芯出口压力保持恒定,应用于小流量恒压控制系统中,做大地提高了液压系统的安全性。

Application of Proportional Solenoid in Cartridge Valve

A new cartridge solenoid valve was introduced. In the valve, secondary control was used to integrate the pilot valve and main spool together to form a cartridge, Comparing to conventional cartridge solenoid valve, this valve＇s solenoid was proportional solenoid, which could be used to adjust pilot valve open and close according to the electromagnetic force and spring force, to make main spool outlet pressure maintain a constance. Applying the valve to small flow system, the safety of the hydraulic system is improved greatly.
