美国科恩科KNKE品牌 进口先导式电磁阀

科恩科KNKE先导式电磁阀，Pilot solenoid valve，通电时，依靠电磁力提起阀杆，导阀口打开，此时电磁阀上腔通过先导孔卸压，在主阀芯周围形成上低下高的压差，在压力差的作用下，流体压力推动主阀芯向上移动将主阀口打开；断电时，在弹簧力和主阀芯重力的作用下，阀杆复位，电磁阀上腔压力升高，流体压力推动主阀芯向下移动，主阀口关闭。

When Konko KNKE pilot operated solenoid valve is energized, the valve stem is lifted by electromagnetic force, and the pilot valve port is opened. At this time, the upper chamber of the solenoid valve relieves pressure through the pilot hole, forming a pressure difference of high, low and high around the main valve core. Under the effect of the pressure difference, the fluid pressure pushes the main valve core upward to open the main valve port; In case of power failure, under the action of spring force and gravity of main valve core, the valve rod resets, the pressure of upper chamber of solenoid valve rises, the fluid pressure pushes the main valve core downward, and the main valve port is closed.
