品牌：RETZ瑞茨/我們一直致力于流體控制領域的持續創新，始于2005……進口油用電磁閥采用先導閥、活塞組合的結構設計,適用于導熱油、潤滑油、機油、柴油、汽油等常溫介質在管路中的自動啟閉，從而達到系統和設備的程序控制或遠程控制The RETZ oil solenoid valve is designed with a combination of pilot valve and piston structure, suitable for automatic opening and closing of normal temperature media such as heat transfer oil, lubricating oil, engine oil, diesel, gasoline, etc. in pipelines, thus achieving program control or remote control of the system and equipment
進口油用電磁閥控制原理--
常閉：normal close
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，閥上腔由活塞節流孔增壓和復位彈簧的推力，電磁閥關閉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
