產品參數(shù)說明:
產品用途
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)境性等的設計均已進行特殊考慮，適用于水、油品、蒸汽等介質。
產品結構特點
1、閥門中腔停滯的壓力異常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，卸壓后閥座自動復位。
2、當萬一發(fā)生火災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，填料裝在填料盤內，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。
