費斯托festo比例調(diào)壓閥導(dǎo)閥的開啟都是利用頂部的調(diào)節(jié)螺栓順時針方向擰動,使彈簧縮產(chǎn)生的彈力,使導(dǎo)閥膜片向下凹陷,作用在導(dǎo)閥連桿上的力,使之向下位移打開導(dǎo)閥。當(dāng)導(dǎo)閥開啟后,上游進汽管段A腔的蒸汽通過α通道(供汽調(diào)節(jié)通道),經(jīng)過導(dǎo)閥進入導(dǎo)閥環(huán)形汽腔,由β通道直接送到下面的活塞汽缸上腔。在A腔蒸汽不斷的供給下,壓力持續(xù)升高,推動活塞下行打開主閥,這時蒸汽*從A腔流至B腔。當(dāng)下游出口管段B腔負荷滿足的情況下,余多的蒸汽又使B腔內(nèi)的壓力不斷升高。不斷升高的壓力通過γ通道(壓力感應(yīng)通道)反饋到導(dǎo)閥膜片下腔,使導(dǎo)閥膜片向上突起,克服了上部調(diào)節(jié)彈簧的壓力,導(dǎo)閥被關(guān)小或關(guān)閉。從而,關(guān)小或關(guān)閉來自上游α通道的蒸汽源。當(dāng)活塞汽缸上腔壓力下降時,在下面復(fù)位彈簧的作用下,主閥被關(guān)小或關(guān)閉,這時B腔內(nèi)的壓力開始下降,這樣周而復(fù)始達到調(diào)壓的目的。費斯托festo比例減壓閥屬高壓閥系列,適用于治金、石油、液壓、水壓試驗機組上。主要用途:是采用節(jié)流耗能達到降壓的功能,能使高壓、超高壓設(shè)備和高壓管道內(nèi)的高壓水通過此閥將高壓水降至低壓所需壓力后排出,使高壓系統(tǒng)壓力均勻降低
