軌道球閥

技術參數 :

口徑:6〞

壓力:600LB

設計标準:API 6D/ASME B16.34

法蘭:ASME B16.5

結構長度:ASME B16.10

結構形式:直通流道,固定球,上裝式

密封形式:金屬密封

材料:閥體WCB,内件F316,閥杆17-4PH,密封面STL

适用工況:石油、化工、城市給排水等要求嚴格切斷的工況

 産品特點:

◇密封面間無摩擦,開啟閥門時,閥杆首先提升使閥球與閥座脫離,然後閥杆驅動閥球轉動到開啟位置;關閉閥門時,閥杆帶動閥球在不接觸閥座的情況下轉動,然後閥杆下降壓迫閥球緊壓在閥座上。

◇閥體結構采用上裝式設計。閥門内部零件的更換和維修可以通過拆卸閥門閥蓋進行在線修理,而不需要将閥門從管線上拆卸下來。

◇單閥座設計,消除了閥門中腔介質因異常升壓而影響使用安全的問題。

◇低扭矩設計,特殊結構設計的閥杆,隻需配一個小手輪閥門就能輕松啟閉。

◇楔形密封結構,閥門是靠閥杆提供的機械力,将球楔壓到閥座上而密封,使閥門的密封性不受管線壓差變化的影響,在各種工況下密封性能都有可靠保證。

◇密封面的自清潔結構,當球體傾離閥座時,管線中的流體沿球體密封面成360°均勻通過,不僅消除了高速流體對閥座局部的沖刷,也沖走了密封面上的聚積物,達到自清潔的目的。

◇緊急注脂結構,閥杆填料配置注油器,可緊急注脂控制逸散性排放。

◇密封面堆焊硬質合金,閥門在苛刻的工況下也能保持良好的嚴密性和長久的使用壽命。
