一、自保持式电磁阀--用途：                                                                                                                                                                                沪甄ZCSTH自保持式电磁阀是水电站冷却水片控系统中替代液动阀的产品。广泛应用于水电、染化、纺织、印染、食品、卷烟、水泥制品、石油化工、冶金、居民用水等部门及其它各工业部门的管路系统中。                                                                                                       二、自保持式电磁阀--工作原理                                                                                                                                                                          电磁导阀采用具有机械式自锁记忆功能的双先导结构的自保持式。当部件线圈“B”通电，电磁阀打开，然后断电，此时电磁阀为常通状态，当部件线圈“A”通电，电磁阀关闭，然后断电，此时电磁阀为常闭状态。若线圈“A”、“B”同时通电，此时电磁阀为常通状态，线圈也不会因此烧坏，因此该阀是双线圈自保持式水液电磁阀换代更新产品                                                                                                                                三、自保持式电磁阀--结构特点：                                                                                                                                                                         电磁部分、密封件全采用特种耐高温电工材料和密封材料，并采用了有效的隔热措施
