襯氟閥門的應用

隨著現代工業的飛躍發展,襯氟閥門及其各類管路附件在石油、印染、化工等各領域中得到迅速應用的推廣,顯示了強大的生命力,做為工程中首選項目已引起各工程設計單位和施工單位的極大關注與青睞,是一種極具市場潛力的朝陽產品。

襯氟閥門的安裝

1、安裝襯氟閥門時,應注意校對閥門標志(如閥門類型、公稱通徑、壓力等級、材料等)是否與使用要求相符合,殼體上的流向標識是否與管道流向一致。

2、安裝襯氟閥門時,盡量做到水平安裝,使閥桿朝上。防止閥門歪斜使閥門在自然狀態下進行安裝,防止閥門因管道、支撐等產生較大的安裝應力,安裝起吊不得利用手輪進行閥門起吊。

3、安裝襯氟閥門時,與閥門兩端氟塑料襯里密封面連接的管道法蘭密封面如果是金屬的,須加氟塑料密封墊片。與之連接的法蘭密封面應按圖A的結構,不采用圖B的結構,否則會導致閥門密封面過早損壞、泄漏。

4、如果管道具有足夠的強度承受閥門的重量和操作力矩,則對此閥門可以不設支承,否則,應對襯氟閥門設專用支承點。

5、安裝襯氟閥門后,在系統或管道進行試壓時,閥門須處于全開位置。
