電動(dòng)調(diào)節(jié)閥使用時(shí)，若發(fā)生外漏現(xiàn)象，我們?cè)撊绾稳��?yīng)對(duì)，這里給大家介紹電動(dòng)調(diào)節(jié)閥外漏的五個(gè)解決方法：

電動(dòng)調(diào)節(jié)閥外漏的五個(gè)解決方法之采用透鏡墊密封法

對(duì)于上、下蓋的密封,閥座與上、下閥體的密封.若為平面密封,在高溫高壓下,密封性差,引起外泄,可以改用電動(dòng)調(diào)節(jié)閥透鏡墊密封,能得到滿意的效果。

電動(dòng)調(diào)節(jié)閥外漏的五個(gè)解決方法之改變流向

置P2在閥桿端法;當(dāng)△P非常大,P1又非常大時(shí),密封P1顯然比密封P2困難.因此,電動(dòng)調(diào)節(jié)閥可采取改變流向的方法,將P1在閥桿端改為P2在閥桿端,這對(duì)壓力高、壓差大的閥是較有效的.如波紋管閥就通常應(yīng)考慮密封P2。

電動(dòng)調(diào)節(jié)閥外漏的五個(gè)解決方法之增加填料法

通常是采用雙層或者多層混合填料的形式單純地增加密封墊片的數(shù)量，如將3片增加到5片，來提高閥桿的密封性能，不過電動(dòng)調(diào)節(jié)閥防漏效果不是很明顯。

電動(dòng)調(diào)節(jié)閥外漏的五個(gè)解決方法之增加密封油脂法

這種方法是針對(duì)還未使用密封油脂的閥體，可以考慮增加密封油脂來提高閥桿的密封性能的。平時(shí)日常維護(hù)電動(dòng)調(diào)節(jié)閥的時(shí)候，增加補(bǔ)充密封油脂也是必要的維護(hù)程序之一。

電動(dòng)調(diào)節(jié)閥外漏的五個(gè)解決方法之是更換石墨填料法

大量被使用的四氟填料，其適用工作溫度在-20～200℃范圍內(nèi)，當(dāng)工作溫度在上限、下限變化非常大時(shí)，電動(dòng)調(diào)節(jié)閥密封性能便明顯下降了，且老化快，壽命短。這里推薦使用柔性石墨填料可以克服四氟填料所不能承受的困難，且使用壽命長，從而提高密封的可靠性。有很多工廠已經(jīng)全部將四氟填料改為石墨填料了，甚至新購買的調(diào)節(jié)閥也將其中的四氟填料換成石墨填料后使用。但是石墨填料也有個(gè)缺點(diǎn)，就是回差大，初時(shí)有的還產(chǎn)生爬行現(xiàn)象，對(duì)此，生產(chǎn)商和使用商在設(shè)計(jì)安裝電動(dòng)調(diào)節(jié)閥設(shè)備時(shí)也要有所考慮。
