產(chǎn)品介紹:DT倒置桶型蒸汽閥有特殊的杠桿結(jié)構(gòu),廣泛用于造紙、紡織 、食品、石油、化工等工業(yè)等加熱設(shè)備的蒸汽管道。
結(jié)構(gòu)特點:
1、結(jié)構(gòu)簡單,不易故障。無插銷或鉸鏈結(jié)構(gòu),無固定磨損,節(jié)能效果佳。耐磨鉻鋼閥座,不銹鋼結(jié)構(gòu),使用壽命長。
2、間歇排放雜質(zhì)均可沖走,不積污垢,自動排空氣。
3、有多種節(jié)流孔選擇,在不同壓力下,可達到zui高排水流量。
4、內(nèi)部零件全安裝在閥蓋上,維修方便。

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(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現(xiàn)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(xiàn)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(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 |
