简单为你介绍：1、先导式：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。

                      2、直动式：通电时，电磁线圈产生电磁力把关闭件从阀座上提起，阀门打                        开；断电时，电磁力消失，弹簧把关闭件压在阀座上，阀门关闭。  简略：                        先导式电磁阀需要以工作介质的压力支撑做为开阀的第2条件。直动式则仅                       依靠电磁力进行工作。
