品牌:RETZ瑞茨/我们一直致力于流体控制领域的持续创新,始于2005……进口先导式电磁阀比较适合大口径场合,高压力工况下使用,需要注意的是,流通的介质-定要大于0.03Mpa的压力才能正确使用本产品广泛应用于蒸汽系统,高压系统,低温系统,工业石油供用系统,灌装系统,液化气系统,供热系统,储灌设备,电厂设备,石化设备,气动设备,管道自控等自动化装置retz The pilot operated solenoid valve is more suitable for large diameter occasions and high pressure conditions. It should be noted that the circulating medium must be greater than 0.03Mpa to use correctly. This product is widely used in steam systems, high-pressure systems, low-temperature systems, industrial oil supply systems, filling systems, liquefied gas systems, heating system, storage and irrigation equipment, power plant equipment, petrochemical equipment, pneumatic equipment, pipeline automation and other automation devices
注解-
1.流体中若含有杂质,电磁阀进端必须安装过滤阀(精度40—200目),
2.电磁阀安装方位无限制。(S-水平安装、C-垂直安装)
3.无粘稠,无凝固及结晶现象。
由先导阀和主阀芯联系形成通道组合而成动作可靠,间接开关,在有压力的情况下正常工作 The combination of a channel formed by the connection between the pilot valve and the main valve core is reliable in action, with an indirect switch that operates normally under pressure
大通径,多种密封形式可选 Large diameter, multiple sealing forms available
进口先导式电磁阀控制原理--
常闭:
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。
