本色品质,精雕细做-德国汉威
原理:它是一种直动和先导式相结合的原理,当入口与出口没有压差时,通电后,电磁力直接把先导小阀和主阀关闭件依次向上提起,阀门打开。当入口与出口达到启动压差时,通电后,电磁力先导小阀,主阀下腔压力上升,上腔压力下降,从而利用压差把主阀向上推开;断电时,先导阀利用弹簧力或介质压力推动关闭件,向下移动,使阀门关闭。
特点:在零压差或真空、高压时亦能可*动作,但功率较大,要求必须水平安装。
广泛应用在航天、船舶重工、石油化工、工业炉窑、锅炉、给排水、采暖空调、消防设备、干燥设备
食品医疗设备、清洗设备、景观灌溉、喷泉、水厂等管道系统中.
It is widely used in aerospace, shipbuilding Heavy
Industry, petrochemical, industrial furnaces, boilers, plumbing, heating and air
conditioning, fire-fighting equipment, drying equipment,Food medical equipment, cleaning equipment, landscape
irrigation, fountains, water and other piping systems
