維護(hù)與檢修
疏水閥運(yùn)行期一般為12個(gè)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(shí)，要及時(shí)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(jī)油在平臺(tái)上研磨，達(dá)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(dá)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(jìn)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(bǔ)泄漏處 |
