用途:杠桿浮球疏水閥,廣泛用于工業(yè)蒸汽加熱設(shè)備,各種大型熱交換器及干燥機(jī),夾套鍋等,特別應(yīng)用于冷凝水特大排量在的工作場(chǎng)合。
Application
Lever-float type stream trapes are widely applied in industrial steam heating equipments ,various large-scale ,drying machines,jacketed kettles,Etc ,especially in occasions where a lot of condensed water needs to drained
特點(diǎn):此超大排量型蒸汽水閥,在整個(gè) 工作壓力范圍 內(nèi)無(wú)需調(diào)整和更換內(nèi)件,即可充分排除大量的凝結(jié)水。排水過冷度可達(dá)0℃,特別適合用于凝結(jié)水量大的工作場(chǎng)合。
Features
Most condensed water could be drained fully by the large—scale steam trap without adjusting or changing internal parts. After draining, the sub- cooled where a large amount of condensed water exists.

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??梢杂?00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(wú)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 |
