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 |
