进口制冷剂电磁阀控制原理--
常闭式:Normallyclosed
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Whenthecoilisenergized,thepilotvalvecoreisclosed,thepilotholeopens,theupperchamberofthevalveisdepressurized,thepistonispushedbythemediumpressureinthelowerchamber,andthesolenoidvalveopens.Whenthecoilispoweredoff,thepilotvalvecoreisresetbythespring,thepilotholeisclosed,andthevalveupperchamberispressurizedbythepistonorificeandthethrustoftheresetspring,andthesolenoidvalveisclosed
