一、自保持式電磁閥--用途：                                                                                                                                                                                滬甄ZCSTH自保持式電磁閥是水電站冷卻水片控系統(tǒng)中替代液動閥的產品。廣泛應用于水電、染化、紡織、印染、食品、卷煙、水泥制品、石油化工、冶金、居民用水等部門及其它各工業(yè)部門的管路系統(tǒng)中。                                                                                                       二、自保持式電磁閥--工作原理                                                                                                                                                                          電磁導閥采用具有機械式自鎖記憶功能的雙先導結構的自保持式。當部件線圈“B"通電，電磁閥打開，然后斷電，此時電磁閥為常通狀態(tài)，當部件線圈“A"通電，電磁閥關閉，然后斷電，此時電磁閥為常閉狀態(tài)。若線圈“A"、“B"同時通電，此時電磁閥為常通狀態(tài)，線圈也不會因此燒壞，因此該閥是雙線圈自保持式水液電磁閥換代更新產品                                                                                                                                三、自保持式電磁閥--結構特點：                                                                                                                                                                         電磁部分、密封件全采用特種耐高溫電工材料和密封材料，并采用了有效的隔熱措施
