ZCZG, ZCZH high temperature solenoid valve
Product Name:
ZCZG, ZCZH high temperature solenoid valve
Description:

ZCZG,ZCZH高温电磁阀的详细资料:

一.特 征

   本阀是先导直动型的电磁阀,其通用介质范围比较广,可分别用水、轻油、重油、非腐蚀性气体及蒸汽等流体,如果电站抽气管道疏水系统和蒸发器的排气系统中,主要的对管道中的介质进行双位自动调节和远程控制。耐高温:采用金属硬密封,提高了使用温度。 耐磨:选材合理,阀杯和导向套间巧妙地利用流体的润滑作用,减少磨损。

电磁阀电磁铁通电时,连杆被提升,带动转轴转动,副阀打开。由于副阀被开启,主阀阀杯上部的压力流体被排出,因此主阀阀杯下部的压力比上部高,这样下部的压力将主阀阀杯向上推开。主阀被打开后,上下压力相等,阀杯在电磁力、上下压力作用下,置于平衡状态,阀门开通。断电时在衔铁自重及返回弹簧作用下,关下副阀,副阀关闭后,随之主阀阀杯上部的压力升高而将主阀阀杯压下,达到断流密封作。
