調(diào)壓步驟
1、關閉減壓閥前的閘閥,開啟減壓閥后的閘閥,制造下游低壓環(huán)境;2、將調(diào)節(jié)螺釘
按逆時針旋轉(zhuǎn)至最上位置(相對最di出口壓力),然后關閉減壓閥后閘閥;
3、慢慢開啟減壓閥前的閘閥至全開;
4、順時針慢慢旋轉(zhuǎn)調(diào)節(jié)螺釘,將出口壓力調(diào)至所需要的壓力(以閥后表壓為準);調(diào)整好后,將鎖緊
螺母鎖緊,打開減壓閥后閘閥;
5、如在調(diào)整時出口壓力高于設定壓力,須從第一步開始重新調(diào)整,即只能從低壓向高壓調(diào)。
主要作用
減壓閥的作用原理是靠閥內(nèi)流道對水流的局部阻力降低水壓,水壓降的范圍由連接閥瓣的薄膜或活塞兩側(cè)的進出口水壓差自動調(diào)節(jié)。定比減壓原理是利用閥體中浮動活塞的水壓比控制,進出口端減壓比與進出口側(cè)活塞面積比成反比。這種減壓閥工作平穩(wěn)無振動;閥體內(nèi)無彈簧,故無彈簧銹蝕、金屬疲勞失效之慮;密封性能良好不滲漏,因而既減動壓(水流動時)又減靜壓(流量為0時);特別是在減壓的同時不影響水流量。
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。介質(zhì)為蒸汽的場合,宜選用先導活塞式減壓閥或先導波紋管式減壓閥。為了操作、調(diào)整和維修的方便,減壓閥一般應安裝在水平管道上。
