品牌：RETZ瑞茨/我們一直致力于流體控制領域的持續(xù)創(chuàng)新，始于2005……進口高溫電磁閥為先導活塞式結構,采用杠桿散熱功能，原理保證線圈和閥體徹底隔離，提高了使用溫度，廣泛應用于吹瓶機械、空壓機、加濕設備、高溫高壓場合、中高溫熱水、中高溫導熱油、高溫蒸汽、過熱蒸汽等、電站抽氣管道疏水系統(tǒng)和蒸發(fā)器的排氣需要高溫控制的系統(tǒng)中The RETZ high-temperature electromagnetic valve is a pilot piston type structure that uses a lever heat dissipation function to ensure complete isolation between the coil and valve body, increasing the operating temperature. It is widely used in bottle blowing machinery, air compressors, humidification equipment, high-temperature and high-pressure occasions, medium to high temperature hot water, medium to high temperature heat transfer oil, high-temperature steam, superheated steam, etc., as well as in systems that require high-temperature control for the drainage system of power station extraction pipelines and the exhaust of evaporators

進口高溫電磁閥工作原理--Working principle of imported high-temperature solenoid valve

常閉式：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(zhì)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，閥上腔由活塞節(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 opens, the upper chamber of the valve is depressurized, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve opens. When the coil is powered off, the pilot valve core is reset by the spring, the pilot hole is closed, and the valve upper chamber is pressurized by the piston orifice and the thrust of the reset spring, and the solenoid valve is closed.

Note: If the outlet pressure is greater than the inlet pressure, the medium will conduct in the opposite direction. Can be installed with a check valve
