*韓國(guó)TKC/YPC/TPC減壓閥/*
減壓閥的工作原理:可以簡(jiǎn)單的理解為入口壓力+出口壓力=彈簧力,通過(guò)控制減壓閥內(nèi)截流口的開(kāi)度大小來(lái)控制出口處的壓力,開(kāi)度越小,液體通過(guò)截流口的液阻越小,壓力損失越小,出口壓力越大,反之則出口壓力越小。
減壓閥的工作原理可以簡(jiǎn)單的理解為入口壓力+出口壓力=彈簧力,如上圖所示:
假設(shè)作用在膜片上的彈簧力為F
作用在減壓閥膜片下的出口壓力為F1 入口壓強(qiáng)為P1 膜片的作用面積為S1 F1=P1×S1
作用在減壓閥閥芯下的入口壓力為F2 出口壓強(qiáng)為P2 閥芯的作用面積為S2 F2=P2×S2
當(dāng)達(dá)到平衡時(shí)則有:F=F1+F2=P1×S1+P2×S2
當(dāng)入口處的壓力出現(xiàn)波動(dòng),假設(shè)入口壓強(qiáng)變大為P2+△P而其他條件不變,則彈簧力F<F1+F2,膜片下的壓力推動(dòng)膜片往上運(yùn)動(dòng),彈簧被壓縮F變大,同時(shí)截流口開(kāi)度變小,液體阻力變大,出口壓強(qiáng)變小,F(xiàn)2變小,一直到達(dá)到新的平衡。
當(dāng)減壓閥出口無(wú)人用水或減壓閥下游被關(guān)閉時(shí),出口壓強(qiáng)持續(xù)增大,F(xiàn)2持續(xù)變大,膜片下的壓力推動(dòng)膜片不斷往上運(yùn)動(dòng)直到減壓閥關(guān)閉,此時(shí)減壓閥出口壓強(qiáng)是大于的設(shè)定值,但由于慣性作用,向上運(yùn)動(dòng)的膜片不會(huì)一下子就停下來(lái),會(huì)繼續(xù)向上運(yùn)動(dòng)一點(diǎn),相當(dāng)于出口處閥腔變大,體積變大,內(nèi)部液體的壓力下降,直到正好等于減壓閥出口的設(shè)定壓力值
