德國GSR先導(dǎo)閥的特點:功率消耗低、通徑較大,而結(jié)構(gòu)簡單、安裝方向任意,但只能用于電磁閥兩端有一定壓差的場合,主要應(yīng)用在汽車,電廠,鋼廠,船廠等行業(yè)。產(chǎn)品應(yīng)用廣泛,質(zhì)量保證。咨詢!
GSR先導(dǎo)閥是一種先導(dǎo)閥與主閥兩者有通道相,當(dāng)電磁閥線圈通電,動鐵芯與靜鐵芯吸合使導(dǎo)閥孔開放,閥芯背腔的壓力通過導(dǎo)閥孔流向出口,此時閥芯背腔的壓力低于進(jìn)口壓力,利用壓差使閥芯脫離主閥口,介質(zhì)從進(jìn)口流向出口。當(dāng)線圈斷電,動鐵芯與靜鐵芯脫離,關(guān)閉了導(dǎo)閥孔,閥芯背腔壓力受進(jìn)口壓力的補充逐漸趨于和進(jìn)口平衡,閥芯因彈簧力作用下把閥門緊密關(guān)閉。 特點:功率消耗低、通徑較大,而結(jié)構(gòu)簡單、安裝方向任意,但只能用于電磁閥兩端有一定壓差的場合,主要應(yīng)用在汽車,電廠,鋼廠,船廠等行業(yè)。

選型依據(jù):
1、根據(jù)管道參數(shù)選擇電磁閥的:通徑規(guī)格(即DN)、接口方式
1)按照現(xiàn)場管道內(nèi)徑尺寸或流量要求來確定通徑(DN)尺寸;
2)接口方式,一般>DN50要選擇法蘭接口,≤DN50則可根據(jù)用戶需要自由選擇。
2、根據(jù)流體參數(shù)選擇電磁閥的:材質(zhì)、溫度組
1)腐蝕性流體:宜選用耐腐蝕電磁閥和全不銹鋼;食用超凈流體:宜選用食品級不銹鋼材質(zhì)電磁閥;
2)高溫流體:要選擇采用耐高溫的電工材料和密封材料制造的電磁閥,而且要選擇活塞式結(jié)構(gòu)類型的;
3)流體狀態(tài):大至有氣態(tài),液態(tài)或混合狀態(tài),特別是口徑大于DN25時一定要區(qū)分開來;
4)流體粘度:通常在50cSt以下可任意選擇,若超過此值,則要選用高粘度電磁閥。
