维护与检修
疏水阀运行期一般为12个月，到期打开出口体清除脏物，清洗滤网，如介质杂质较多，可以酌情提前清洗。疏水阀由于使用过久可能有封闭不严现象，这时，要及时更换或维修（如维修：打开出口体，把阀盖卸下打开，检查阀片，阀座密封是否磨损。可以用600目金钢砂混机油在平台上研磨，达到电二件互为密封为止。）
| 故障现象 | 可能原因 | 解决方法 |
| 漏汽 | 1 ．阀片、阀座的密封面严重磨损； | 研磨密封面，使其达到密封； |
| 2 ．密封面上存有污垢或水锈 | 打开阀盖清除污垢或水锈 | |
| 3 ．阀前无凝结水、蒸汽过热 | 关闭疏水阀前截止阀 | |
| 连续排水 | 阀盖没有拧紧或者阀盖有泄漏蒸汽直接进入控制，使阀片打不开。 | 旋紧阀盖或排除泄漏处，可用耐高温密封胶修补泄漏处 |
