維護與檢修
疏水閥運行期一般為12個月,到期打開出口體清除臟物,清洗濾網(wǎng),如介質(zhì)雜質(zhì)較多,可以酌情提前清洗。疏水閥由于使用過久可能有封閉不嚴(yán)現(xiàn)象,這時,要及時更換或維修(如維修:打開出口體,把閥蓋卸下打開,檢查閥片,閥座密封是否磨損。可以用600目金鋼砂混機油在平臺上研磨,達到電二件互為密封為止。)
故障現(xiàn)象 | 可能原因 | 解決方法 |
漏汽 | 1 .閥片、閥座的密封面嚴(yán)重磨損; | 研磨密封面,使其達到密封; |
2 .密封面上存有污垢或水銹 | 打開閥蓋清除污垢或水銹 | |
3 .閥前無凝結(jié)水、蒸汽過熱 | 關(guān)閉疏水閥前截止閥 | |
連續(xù)排水 | 閥蓋沒有擰緊或者閥蓋有泄漏蒸汽直接進入控制,使閥片打不開。 | 旋緊閥蓋或排除泄漏處,可用耐高溫密封膠修補泄漏處 |
