進(jìn)口防腐電磁閥工作原理：

常閉：當(dāng)線圈通電時(shí)，先導(dǎo)閥芯吸合，先導(dǎo)孔打開(kāi)，閥上腔卸壓，活塞靠下腔介質(zhì)壓力推動(dòng)，電磁閥打開(kāi)。

當(dāng)線圈斷電時(shí)，先導(dǎo)閥芯靠彈簧復(fù)位，先導(dǎo)孔關(guān)閉，閥上腔由活塞節(jié)流孔增壓和復(fù)位彈簧的推力，電磁閥關(guān)閉。

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.
 

進(jìn)口防腐電磁閥描述：

德國(guó)《DE LOCKE》洛克進(jìn)口防腐電磁閥（Solenoid valve ）適用于各種強(qiáng)酸強(qiáng)堿類(lèi)氣液體為工作介質(zhì)，并廣泛應(yīng)用于醫(yī)療制藥、化工化學(xué)、環(huán)?；蚯逑丛O(shè)備等自動(dòng)化控制系統(tǒng)作介質(zhì)管路的通斷。閥體為聚四氟乙烯(塑料王)制造,膜片采用氟橡膠或聚四氟乙烯,其它零件與液體介質(zhì)完全隔離。

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.
