Q347H高壓鍛鋼球閥
固定鍛鋼高壓球閥適用于Class 150~600Lb,工作溫度<150℃的長輸管線和一般工業(yè)管線,其安全、耐惡劣環(huán)境性等的設(shè)計均已進行特殊考慮,適用于水、油品、蒸汽等介質(zhì)。
產(chǎn)品結(jié)構(gòu)特點
1、閥門中腔停滯的壓力異常超過彈簧的預(yù)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(fù)位。
2、當(dāng)萬一發(fā)生火災(zāi)或由于異常升溫使閥座密封圈燒損或軟化時,在彈簧和介質(zhì)壓力作用下,使支撐圈球面部位和球體形成金屬對金屬接觸,達到暫時密封作用,阻止了火災(zāi)進一步擴大,符合API 6FA的規(guī)定。
3、填料壓蓋部位密封采用PTFR填料和0形密封圈雙重密封圈,特別適用于氣體介質(zhì),填料裝在填料盤內(nèi),可隨時采用摩擦系統(tǒng)低的新型SF型自潤滑滑動軸襯,減低操作力矩。
