Q347F蝸輪固定式球閥結構及用途
三分體式連接鍛鋼固定球閥,系將閥體在兩閥座部位沿與閥門通道軸線相垂直的截面分為三部分,整臺閥門沿閥桿中心軸左右對稱,它在管道上主要用于切斷、分配和改變介質流動方向。它的大樞軸結構保證在高壓下準確的球體中心位置,保證了閥門良好的操作性能;標準閥座采用彈簧結構,將閥座推向球體,保證了良好的進出口雙向密封性能;利用自帶的排放閥,閥體中腔可向外排放;樞軸采用防吹出保護結構,有效地防止泄漏;低磨擦系數的軸承,使得扭矩減少到最小,便于閥門啟閉;閥桿與閥體有效的接觸,使防靜電接地裝置性能優越等。具有性能優異,可靠性高,用途廣泛,價格合理等優點。
適用于:化工、石油、天然氣、冶金、等行業及含硫化氫介質、雜質多、腐蝕嚴重的天然氣長輸管線。
