诺冠无杆气缸

    诺冠无杆气缸自保持型电磁阀就是只需瞬间通电即完成阀门开关动作,阀芯位置不需电来保持。它的优点在于节约能源尤其是用电池作电源的场合，而且可不考虑温升，从而线圈寿命长，在高低温、防爆等场合有较高安全性。常见的有机械式保持和永磁体保持，又分双线圈和单线圈，以单线圈磁保持结构zui为简单。它是以改变直流电源极性改变对应阀门开关的两种状态。这种电磁阀单独安装线圈外部接线需加转换开关，而与智能仪表配套则十分方便。IC卡预收费煤气表和水表所配的电磁阀是仪表成败的关键之一，其中的自保持技术又是电磁阀的成败的重要因素。

   诺冠无杆气缸活塞通过磁力带动缸体外部的移动体做同步移动。它的工作原理：在活塞上安装一组高强磁性的*磁环，磁力线通过薄壁缸筒与套在外面的另一组磁环作用，由于两组磁环磁性相反，具有很强的吸力。当活塞在缸筒内被气压推动时，则在磁力作用下，带动缸筒外的磁环套一起移动。气缸活塞的推力必须与磁环的吸力相适应。
