工作原理
減壓閥出廠時,調(diào)節(jié)彈簧處于未壓縮狀態(tài),此時主閥瓣和副閥瓣處于關(guān)閉狀態(tài),使用時按順時針轉(zhuǎn)動調(diào)節(jié)螺釘,壓縮調(diào)節(jié)彈簧,使膜瓣移頂開付閥瓣,介質(zhì)由a孔通過付閥座到b孔進入活塞上方,活塞在介質(zhì)壓力的作用下,向下移動推動主閥瓣離開主閥座,使介質(zhì)流向閥后.同時由c孔進入膜片下方,當(dāng)閥后壓力超過調(diào)定壓力時,推動膜片上移壓縮調(diào)節(jié)彈簧,付閥瓣隨之向關(guān)閉方向移動,使流入活塞上方的介質(zhì)減小,壓力也隨之下降,此時的主閥瓣在主閥瓣彈簧力的推動上下移,使主閥瓣與主閥座的間隙減小,介質(zhì)流量也隨之減小,使閥后壓力也隨之下降到新的平衡,反之當(dāng)閥后壓力低于調(diào)定壓力時,主閥瓣與主閥座的間隙增大,介質(zhì)流量也隨之增加,使閥后壓力也隨之增高達到新的平衡.
減壓閥的安裝與維護蒸汽減壓閥的安裝與維護應(yīng)注意以下事項:
手輪、手柄及傳動機構(gòu)均不允許作起吊用,并嚴禁碰撞。
雙閘板閘閥應(yīng)垂直安裝(即閥桿處于垂直位置 , 手輪在頂部 )。
帶有旁通閥的閘閥在開啟前應(yīng)先打開旁通閥(以平衡進出口的壓差及減小開啟力 )。
帶傳動機構(gòu)的閘閥,按產(chǎn)品使用說明書的規(guī)定安裝。
如果閥門經(jīng)常開關(guān)使用 , 每月至少潤滑一次。
C,安裝與使用1.減壓閥Y43H-16,備有0.05~0.4MPa,Y43H-25,備有1~1.6MPa,Y43H-40,備有1~1.6MPa,1.6~2.5MPa調(diào)節(jié)彈簧,Y43H-64,備有1~3MPa調(diào)節(jié)彈簧,出廠時閥內(nèi)裝有0.1~1MPa,彈簧,其余隨閥附帶,用戶可根據(jù)所量的出口壓力值選裝.2.安裝減壓閥之前必須對管路系統(tǒng)進行沖洗清理.以防焊渣,氧化皮等贓物流入閥內(nèi),影響閥門正常工作.3.減壓閥應(yīng)安裝在便于操作和維修的地方,并且必須直立安裝在水平管道上,(見安裝示意圖),應(yīng)注意使管路中介質(zhì)的流向與閥體上箭頭所示方向*,切勿反裝,4.減壓閥在安裝使用時,應(yīng)把旁通管道的截止閥打開,排除管路中的冷凝水和汽水的混合物,以防減壓閥開啟時產(chǎn)生水圾現(xiàn)象損壞減壓閥,當(dāng)無異常現(xiàn)象后,按順時針方向緩慢旋轉(zhuǎn)調(diào)節(jié)螺釘,將出口壓力調(diào)至所需的壓力(以閥后表壓為準(zhǔn)),調(diào)整后,將鎖緊螺母背緊,擰上防護罩.5.減壓閥前應(yīng)安裝過濾器,以防介質(zhì)中的雜物進入減壓閥,影響其性能.6.安裝的減壓閥前后應(yīng)有一段直管,閥前的直管長度約為6DN毫米,閥后的直管長度約為10DN毫米.
你的蒸汽管道上的減壓閥和目前管道壓力不匹配。但從基本原理上來說,還是可以通過蒸汽的。因為減壓閥是由出口的壓力來控制的,現(xiàn)在出口的壓力不夠,主閥是處于全開狀態(tài)的。
但如果長期下去還是有一定的問題的,所以才有一般減壓閥都要求進出口壓差必須≥0.2Mpa。
減壓閥通常有DN15~DN350等多種規(guī)格,閥前、后的工作壓力分別為<1MPa和0.1~0.5MPa,調(diào)壓范圍誤差為±5%~10%。
應(yīng)該看到,水流通過減壓閥雖有很大的水頭損失,但由于減少了水的浪費并使系統(tǒng)流量分布合理、改善了系統(tǒng)布局與工況,因此總體上講仍是節(jié)能的。
