不同类型电磁阀的工作原理

追朔电磁阀的发展史，到目前为止，国内外的电磁阀从原理上分为三大类(即:直动式、分步童先导式)，而丛阀瓣结构和材料

向上提起，阀门打开，当入口与出口达到启动压差时，通电后，电磁力先导小液，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。先导式电磁阀:

原理:通电时，电磁力把先导孔打开，上腔室压力迅速下降，在关闭件周围形成上低下高的压差，流体压力推动关闭件向上移动，

阀门打开;断电时，弹簧力把先导孔关闭，入口压力通过旁通孔迅速腔室在关阀件周围形成下低上高的压差，流体压力推动关闭件

向下移动，关闭阀门。

特点:流体压力范围上限较高，可任意安装(需定制)但必须满足流体压差条件。
