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，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
