德国博士REXROTH力士乐电磁阀的详细资料：
BOSCH气缸，德国博士REXROTH力士乐电磁阀原理及维修 纵观国内外电磁阀，到目前为止，从动作方式上可分为三大类即：直动式、反冲式、先导式，而从阀瓣结构和材料上的不同以及原理上的区别反冲式又可分为：膜片式反冲电磁阀、活塞式反冲电磁阀；先导式又可分为：先导式膜片电磁阀、先导式活塞电磁阀；从阀座及密封材料上分又可分为：软密封电磁阀、钢性密封电磁阀、半钢性密封电磁 一、直动式电磁阀 原理：常闭型直动式电磁阀通电时，电磁线圈产生电磁吸力把阀芯提起，使关闭件离远开阀座密封副打开；断电时，电磁力消失，靠弹簧力把关闭元件压在阀座上阀门关闭。(常开型与此相反) 特点：在真空、负压、零压差时能正常工作，DN50以下可任意安装，但电磁头体积较大。如我公司引进HERION公司技术生产的直动电磁阀可用于1.33×10-4 Mpa真空。
二、BOSCH气缸，德国博士REXROTH力士乐电磁阀原理反冲型电磁阀 '原理：它的原理是一种直动和先导相结合，通电时，电磁阀先将辅阀打开，主阀下腔压力大于上腔压力而利用压差及电磁阀的同时作用把阀门开启；断电时，辅阀利用弹簧力或介质压力推动关闭件，向下移动便阀门关闭。 特点：在零压差或高压时也能可靠工作，但功率及体积较大， 三、先导式电磁阀 原理：通电时，电磁力驱动先导阀打开先导阀，主阀上腔压力迅速下降，在主阀上下腔内形成压差，依靠介质压力推动主阀关闭件上移，阀门开启；断电时，弹簧力把先导阀关闭，入口介质压力通过先导孔迅速进入主阀上腔在上腔内形成压差，从而使主阀关闭。 特点：体积小，功率低，但介质压差范围受限，必须满足压差条件。 两位三通电磁阀通常与单作用气动执行机构配套使用，两位是两个位置可控：开-关，三通是有三个通道通气，一般情况下1个通道与气源连接，另外两个通道1个与执行机构的进气口连接0820024054?R480059375 0821305215?R480073342
