供应进口分步直动式电磁阀

进口分步直动式电磁阀工作原理:
常闭：当线圈通电时，电磁力先打开先导孔，主阀活塞上腔压力下降，从而利用压差和电磁力吸动先导阀芯连动主活塞，电磁阀打开。 当线圈断电时，靠弹簧复位关闭先导孔，主活塞上腔增压，推动主活塞向下移动，电磁阀关闭。
常开：常开与常闭相反。
注：出口端压力大于进口端压力时，介质会反向导通。可安装止回阀或订制带止回功能的电磁阀。
Import stepped direct-acting solenoid valve working principle:
Normally closed: when the coil is energized, the electromagnetic force to open the pilot hole, the main valve piston chamber pressure drops, thus the use of pressure and electromagnetic force sucking the pilot valve core linking the main piston, the electromagnetic valve is opened. When the coil power, by the reset spring close the pilot hole, the main piston cavity pressure, promote the main piston moves down, the electromagnetic valve is closed.
Normally open: normally open and normally closed instead.
Note: outlet pressure is greater than the inlet pressure, the medium will reverse 
conduction. Electromagnetic valve check valve can be installed or ordered with non-return function.
