进口防腐电磁阀优点：

 a.电磁阀零泄漏

 b. 电磁阀流量孔径为标准值，满足相对应的流量要求。

 c. 电磁阀对流体中的颗粒物、沉淀物适应性强，应用在污水处理、农林灌溉、海水淡化、海水养殖。工业过程中的酸性、碱性流体尤其在如磷酸等易结晶流体方面具有明显的优势。

 

进口防腐电磁阀工作原理：

常闭：当线圈通电时，先导阀芯吸合，先导孔打开，阀上腔卸压，活塞靠下腔介质压力推动，电磁阀打开。

当线圈断电时，先导阀芯靠弹簧复位，先导孔关闭，阀上腔由活塞节流孔增压和复位弹簧的推力，电磁阀关闭。

常开：当线圈通电时，先导阀芯靠弹簧复位，先导孔关闭，阀上腔由活塞节流孔增压和复位弹簧的推力，电磁阀关闭。

当线圈断电时，先导阀芯靠弹簧复位，先导孔打开，阀上腔卸压，活塞靠下腔介质压力推动，电磁阀打开。

注：出口端压力大于进口端压力，介质会反向导通。可安装止回阀。

Working principle of imported anti-corrosion solenoid valve:
Normally closed: when the coil is energized, the pilot valve core is closed, the pilot hole is opened, the pressure in the upper chamber of the valve is relieved, the piston is pushed by the medium pressure in 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 upper chamber of the valve 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 valve core is reset by the spring, the pilot hole is closed, the upper chamber of the valve is pressurized by the piston orifice and the thrust of the reset 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 relieved, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve is opened.
Note: if the outlet pressure is greater than the inlet pressure, the medium will conduct reversely. Check valves can be installed.
 

进口防腐电磁阀描述：

德国《DE LOCKE》洛克进口防腐电磁阀（Solenoid valve ）适用于各种强酸强碱类气液体为工作介质，并广泛应用于医疗制药、化工化学、环保或清洗设备等自动化控制系统作介质管路的通断。阀体为聚四氟乙烯(塑料王)制造,膜片采用氟橡胶或聚四氟乙烯,其它零件与液体介质完全隔离。

Description of imported anti-corrosion solenoid valve:
German "de Locke" imported anti-corrosion solenoid valve is suitable for all kinds of strong acid and alkali gas and liquid as working medium, and is widely used in Medical Pharmacy, chemical industry, environmental protection or cleaning equipment and other automatic control systems for medium pipeline on and off. The valve body is made of polytetrafluoroethylene (plastic king), the diaphragm is made of fluororubber or polytetrafluoroethylene, and other parts are completely isolated from the liquid medium.
