阿托斯比例減壓閥LIRZ0-AE-3/210   調(diào)壓步驟
1、關(guān)閉減壓閥前的閘閥，開(kāi)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(shí)針旋轉(zhuǎn)至最上位置（相對(duì)最di出口壓力），然后關(guān)閉減壓閥后閘閥；
3、慢慢開(kāi)啟減壓閥前的閘閥至全開(kāi)；
4、順時(shí)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(zhǔn)）；調(diào)整好后，將鎖緊
螺母鎖緊，打開(kāi)減壓閥后閘閥；
5、如在調(diào)整時(shí)出口壓力高于設(shè)定壓力，須從第一步開(kāi)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(duì)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(jìn)出口水壓差自動(dòng)調(diào)節(jié)。定比減壓原理是利用閥體中浮動(dòng)活塞的水壓比控制，進(jìn)出口端減壓比與進(jìn)出口側(cè)活塞面積比成反比。這種減壓閥工作平穩(wěn)無(wú)振動(dòng)；閥體內(nèi)無(wú)彈簧，故無(wú)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(dòng)壓（水流動(dòng)時(shí)）又減靜壓（流量為0時(shí)）；特別是在減壓的同時(shí)不影響水流量。
