Z41H美標法蘭閘閥特點
Z41H美標法蘭閘閥流體阻力小，適用的壓力、溫度范圍大，介質流動方向不受限制，密封性能良好。
Z41H美標法蘭閘閥安裝要點
1）、安裝位置、高度、進出口方向必須符合設計要求，連接應牢固緊密。
2）、安裝在保溫管道上的各類手動閥門，手柄均不得向下。
3）、閥門安裝前必須進行外觀檢查，閥門的銘牌應符合現行國家標準《通用閥門標志》GB 12220的規定。對于工作壓力大于1.0 MPa 及在主干管上起到切斷作用的閥門，安裝前應進行強度和嚴密性能試驗，合格后方準使用。強度試驗時，試驗壓力為公稱壓力的1.5倍，持續時間不少于5min，閥門殼體、填料應無滲漏為合格。嚴密性試驗時，試驗壓力為公稱壓力的1.1倍；試驗壓力在試驗持續的時間應符合GB 50243標準要求，以閥瓣密封面無滲漏為合格。
