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)，如介質雜質較多，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?？梢杂?00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 ．閥前無凝結水、蒸汽過熱 | 關閉疏水閥前截止閥 | | 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
