進口低溫不銹鋼電磁閥產品列表德國洛克

一、進口低溫不銹鋼電磁閥工作原理：

常閉：當線圈通電時，先導閥芯吸合，先導孔打開，閥上腔卸壓，活塞靠下腔介質壓力推動，電磁閥打開；當線圈斷電時，先導閥芯靠彈簧復位，先導孔關閉，閥腔由活塞節(jié)流孔增壓和復位彈簧的推力，電磁閥關閉。

Normally closed: when the coil is energized, the pilot valve core is closed, the pilot hole is opened, the upper chamber of the valve is depressurized, the piston is pushed by the medium pressure of the lower chamber, and the solenoid valve is opened; when the coil is powered off, the pilot valve core is reset by the spring, the pilot hole is closed, the valve chamber is pressurized by the piston orifice and the thrust of the reset spring, and the solenoid valve is closed.

Normally open: when the coil is energized, the pilot hole is closed, the upper chamber of the valve is pressurized by the piston orifice and the thrust of the return spring, and the solenoid valve is closed. When the coil is powered off, the pilot valve core is reset by the spring, the pilot hole is opened, the pressure in the upper chamber of the valve is released, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve is opened.
