費(fèi)斯托減壓閥的分類(lèi):按結(jié)構(gòu)形式可分為薄膜式、彈簧薄膜式、活塞式、杠桿式和波紋管式;按閥座數(shù)目可人為單座式和雙座式;按閥瓣的位置不同可分為正作用式和反作用式。費(fèi)斯托festo先導(dǎo)式減壓閥內(nèi)部先導(dǎo)式減壓閥當(dāng)減壓閥的輸出壓力較高或通徑較大時(shí),用調(diào)壓彈簧直接調(diào)壓,則彈簧剛度必然過(guò)大,流量變化時(shí),輸出壓力波動(dòng)較大,閥的結(jié)構(gòu)尺寸也將增大。為了克服這些缺點(diǎn),可采用先導(dǎo)式減壓閥。先導(dǎo)式減壓閥的工作原理與直動(dòng)式的基本相同。先導(dǎo)式減壓閥所用的調(diào)壓氣體,是由小型的直動(dòng)式減壓閥供給的。若把小型直動(dòng)式減壓閥裝在閥體內(nèi)部,則稱(chēng)為內(nèi)部先導(dǎo)式減壓閥;若將小型直動(dòng)式減壓閥裝在主閥體外部,則稱(chēng)為外部先導(dǎo)式減壓閥。與直動(dòng)式減壓閥相比,增加了由噴嘴4、擋板3、固定節(jié)流孔9及氣室B所組成的噴嘴擋板放大環(huán)節(jié)。當(dāng)噴嘴與擋板之間的距離發(fā)生微小變化時(shí),就會(huì)使B室中的壓力發(fā)生根明顯的變化,從而引起膜片10有較大的位移,去控制閥芯6的上下移動(dòng),使進(jìn)氣閥口8開(kāi)大或關(guān)小、提高了對(duì)閥芯控制的靈敏度,即提高了穩(wěn)壓精度。
