工作原理：
Working principle.
常閉：當(dāng)線圈通電時，電磁鐵芯吸合，卸壓孔打開，主活塞由介質(zhì)壓力推動，打開主閥口，介質(zhì)流通。
Normally closed: when the coil is energized, the solenoid core pull, pressure relief hole is opened, the main piston driven by the pressure of the medium, the main valve port is opened, the media flow.
當(dāng)線圈斷電時，主閥口關(guān)閉，介質(zhì)截止。
When the coil power, the main valve port closed, medium s.
