进口水用电磁阀通常采用先导式结构,适用于中性纯净气体或液体、水、热水、冷冻水、循环水、除盐水、海水等管路的自动化控制系统,从而达到系统和设备的程序控制或远程控制TheRETZwatersolenoidvalveusuallyadoptsapilottypestructureandissuitableforautomaticcontrolsystemsofneutralpuregasorliquid,water,hotwater,chilledwater,circulatingwater,desalinatedwater,seawater,andotherpipelines,inordertoachieveprogramcontrolorremotecontrolofthesystemandequipment.

进口水用电磁阀控制原理--

常闭型：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Normallyclosedtype:Whenthecoilisenergized,thepilotvalvecoreisclosed,thepilotholeisopened,theupperchamberofthevalveisdepressurized,thepistonispushedbythemediumpressureinthelowerchamber,andthesolenoidvalveisopened;Whenthecoilispoweredoff,thepilotvalvecoreisresetbythespring,thepilotholeisclosed,andthevalveupperchamberispressurizedbythepistonorificeandthethrustoftheresetspring,andthesolenoidvalveisclosed.
