固定式電動球閥產品概述
固定式電動球閥系列產品采用上下兩根閥桿固定球體結構,依靠閥座彈簧預緊力介質推力共同作用達到密封效果,適用高壓力和大口管線,特別是公稱壓力在10.0MPa以上,公稱通徑DN250以上的管路中,固定球閥廣泛應用于石油煉制、長輸管線、化工、造紙、制藥、水利、電力、市政、鋼鐵等領域。固定式電動球閥產品特點
1、操作省力:球體由上下軸承支撐,減少摩擦,消除了由于進口壓力推動球體與密封座形成的巨大密封負荷而造成過大的扭矩;2、密封性能可靠:PTFE單性材料密封圈嵌于不銹鋼閥座內,金屬閥座尾端設有彈簧保證密封圈足夠的預緊力,閥門在使用過程中密封面磨損時,在彈簧作用下閥門繼續保證良好密封性能;
3、防火結構:為防止由于驟熱或火災的出現,使聚四氟乙烯密封圈燒毀,發生較大泄漏,而助長火勢,在球體與閥座間設置防火密封環,在密封圈燒毀時,在彈簧力作用下,將閥座密封環迅速推向球體上,形成金屬與金屬密封,起到一定程度的密封效果。耐火試驗符合APl6FA和APl607標準要求;
4、自動泄壓功能:當閥門中腔停滯的介質壓力異常升高超過彈簧的預緊力時,閥座后退脫離球體,達到自動泄壓的效果,卸壓后閥座自動復;
5、排泄管路:閥體上下均設置排泄孔,可檢查閥座是否發生泄漏,在工作中,閥門處于全開或全關時,卸掉中腔壓力,可直接更換填料;可以排放中腔滯留物,減少介質對閥門的污染。
