CamozziKN000-303-KY3 电磁阀

原理：通电时，电磁阀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，弹簧力把关闭件压在阀座上，阀门关闭。特点：在真空、 负压、零压时能正常工作，但通径一般不超过25mm。

CamozziKN000-303-KY3 电磁阀

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，电磁力先打开先导小阀，主阀下压力上升，上腔压力下降，从而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：在零压或真空、高压时亦能可靠动作，但功率较大，要求必须水平安装。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进入上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。电-气转化组件将电讯号转化为气动讯号，电气讯号输入控制了气动输出。常用的电-气转换组件是电磁阀(Solenoidactuatedvalves)。电磁阀既是电器控制部分和气动执行部分的接口，也是和气源系统的接口。电磁阀接受命令 去释放，停止或改变压缩空气的流向，在电-气动控制中，电磁阀可以实现的功能有：气动执行组件动作的方向控制，ON/OFF开关量控制，OR/NOT/AND 逻辑控制。在电磁阀家族中，重要的是电磁控制换向阀
