A41Y水用安全閥產(chǎn)品說明
A41H型水用安全閥(彈簧微啟封閉式安全閥)適用于工作溫度≤300℃的石油氣
彈簧是在較高應力下工作,材料表面受力大
彈簧鋼制作的彈簧
,硬度高低與平面應變斷裂韌性關系極大,隨著硬度增加A41Y水用安全閥進出口管進口管道設計
許多安全閥不能正常動作
通常要求安全閥排放時,進口管道中的壓力降不超過閥門啟閉壓差(整定壓力與回座壓力之差)的50%
1.安全閥一般應盡量靠近保護設備或管道安裝,安裝位置要易于檢修和檢驗
2.如果幾個安全閥共用一個入口管道時,入口管道要滿足幾個安全閥的流量要求
3.安全閥設置在管道上,對于壓縮機等大型設備振動源

A41Y水用安全閥出口管道設計
1.排放管道設計基本要求
(1) 排放管對安全閥動作和性能也有很大的影響,為此
1)排放管的通徑應不小于安全閥出口通徑,這是基本原則
2)排放管的阻力應盡可能小。在排放時
,排放管道中的阻力壓降應小于閥門整定壓力值的10%。以避免造成過大背壓,影響閥門動作。3)管道應加以適當?shù)闹?div id="4qifd00" class="flower right">
4)原則上一個安全閥單獨使用一個排放管。當兩個以上安全閥共用一根集合管時
5)在排放管的低處應設置適當?shù)呐盼劭撞⒍ㄆ谂盼?div id="m50uktp" class="box-center"> ,防止雨、雪
、冷凝液等積聚在排放管中。6)安全閥與進口管
、排放管的連接螺栓應均勻把緊,以防止對閥門產(chǎn)生附加應力。開啟壓力:也叫額定壓力
,是指安全閥閥瓣在運行條件下開始升起時的進口壓力,在該壓力下,開始有可測量的開啟高度,介質(zhì)呈可由視覺或聽覺干支的連續(xù)排放狀態(tài)。A41Y水用安全閥的調(diào)試
1.整定壓力的調(diào)整
在規(guī)定的工作壓力范圍內(nèi)
在調(diào)節(jié)整定壓力時
(1)當介質(zhì)壓力接近整定壓力(達到整定壓力的90%以上)時
(2)為保證整定壓力值準確
安全閥應定期進行檢驗
