進口氧氣電磁閥
原理結(jié)構(gòu):分步直動導(dǎo)向活塞式
原理:通電時,電磁線圈產(chǎn)生電磁力把關(guān)閉件從閥座上提起,閥門打開;斷電時,電磁力消失,彈簧把關(guān)閉件壓在閥座上,閥門關(guān)閉。
特點:在真空、負(fù)壓、零壓時能正常工作,但通徑一般不超過25mm。
工作環(huán)境溫度:-20-+50℃、-40-+80℃
線圈工作溫度:<+50℃、<+85℃
進口氧氣電磁閥詳細(xì)技術(shù)參數(shù):http:///cn/products/613.htm
控制方式:常開(通電關(guān)閉,斷電打開);常閉(斷電關(guān)閉,通電打開)
標(biāo)準(zhǔn)電壓:AC220V、DC24V
介質(zhì):氧氣、氦氣、液氨、酒精、液氧等
溫度:<-40℃、<-100℃、<-120℃、<-200℃、
壓力:1bar、3bar、6bar、10bar、16 bar、25 bar
閥體材質(zhì): 不銹鋼體(304、316),鑄鋼(WCB)
線圈連接方式:鐵罩引線、塑封線盒插頭
密封材質(zhì)性能:耐高溫、耐壓、耐磨、防腐
泄漏量:零
密封結(jié)構(gòu):圓弧錐線與錐面密封
性能特點:通用性廣、靈敏性高、嚴(yán)密性強、壽命性長
工作范圍:冶金工業(yè)、石油化工、電力設(shè)備、低溫設(shè)備、液氮設(shè)備、冷卻設(shè)備、實驗設(shè)備等
注解:
1、流體中若含有雜質(zhì),電磁閥進端必須安裝過濾閥(30——80目/寸),且無凝固及結(jié)晶現(xiàn)象。
2、電磁閥安裝方位無限制。(S-水平安裝、C-垂直安裝)
