產(chǎn)品詳細(xì)說(shuō)明
Q647型氣動(dòng)固定式球閥的球體.采用上、下兩根閥桿固定.工作時(shí),流體壓力不會(huì)使球體向閥座移動(dòng),閥座不會(huì)承受過(guò)大壓力而變形。閥桿部分設(shè)有自潤(rùn)滑軸承,減少磨擦,開關(guān)扭距小,兩閥座均采用彈簧設(shè)預(yù)緊。密封采用聚四氟乙烯鑲?cè)脘摴虄?nèi),鋼圈后部設(shè)有彈簧,保證閥座緊貼球體。當(dāng)閥門中腔壓力異常升高超過(guò)彈簧頂緊力,閥座后退脫離球體,達(dá)到自動(dòng)泄壓效果,壓后閥座自動(dòng)復(fù)位。結(jié)構(gòu)的*性使固定球閥的密封性能穩(wěn)定操作省力,使用壽命長(zhǎng) ,極適用于長(zhǎng)輸管線和一般管線。
