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(dòng)閥的產(chǎn)品。廣泛應(yīng)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(dǎo)閥采用具有機(jī)械式自鎖記憶功能的雙先導(dǎo)結(jié)構(gòu)的自保持式。當(dāng)部件線圈“B"通電，電磁閥打開，然后斷電，此時(shí)電磁閥為常通狀態(tài)，當(dāng)部件線圈“A"通電，電磁閥關(guān)閉，然后斷電，此時(shí)電磁閥為常閉狀態(tài)。若線圈“A"、“B"同時(shí)通電，此時(shí)電磁閥為常通狀態(tài)，線圈也不會(huì)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(chǎn)品                                                                                                                                三、自保持式電磁閥--結(jié)構(gòu)特點(diǎn)：                                                                                                                                                                         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
