工作原理
減壓閥是氣動(dòng)調(diào)節(jié)閥的一個(gè)必備配件，主要作用是將氣源的壓力減壓并穩(wěn)定到一個(gè)定值，以便于調(diào)節(jié)閥能夠獲得穩(wěn)定的氣源動(dòng)力用于調(diào)節(jié)控制。 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)目可分為單座式和雙座式；按閥瓣的位置不同可分為正作用式和反作用式。

直動(dòng)式減壓閥所示為直動(dòng)式帶溢流閥的減壓閥(簡稱溢流減壓閥)的結(jié)構(gòu)圖。
溢流減壓閥是靠進(jìn)氣口的節(jié)流作用減壓，靠膜片上力的平衡作用和溢流孔的溢流作用穩(wěn)壓；調(diào)節(jié)彈簧即可使輸出壓力在一定范圍內(nèi)改變。為防止以上溢流式減壓閥徘出少量氣體對周圍環(huán)境的污染，可采用不帶溢流閥的減壓閥(即普通減壓閥)。

壓力控制按用途分為溢流閥﹑減壓閥和順序閥。⑴溢流閥：能控制液壓系統(tǒng)在達(dá)到調(diào)定壓力時(shí)保持恒定狀態(tài)。用於過載保護(hù)的溢流閥稱為安全閥。當(dāng)系統(tǒng)發(fā)生故障，壓力升高到可能造成破壞的限定值時(shí)，閥口會打開而溢流，以保證系統(tǒng)的安全。⑵減壓閥：能控制分支回路得到比主回路油壓低的穩(wěn)定壓力。減壓閥按它所控制的壓力功能不同，又可分為定值減壓閥（輸出壓力為恒定值）﹑定差減壓閥（輸入與輸出壓力差為定值）和定比減壓閥（輸入與輸出壓力間保持一定的比例）。⑶順序閥：能使一個(gè)執(zhí)行元件（如液壓缸﹑液壓馬達(dá)等）動(dòng)作以后，再按順序使其他執(zhí)行元件動(dòng)作。油泵產(chǎn)生的壓力先推動(dòng)液壓缸1運(yùn)動(dòng)，同時(shí)通過順序閥的進(jìn)油口作用在面積A 上，當(dāng)液壓缸1運(yùn)動(dòng)完全成后，壓力升高，作用在面積A 的向上推力大於彈簧的調(diào)定值后，閥芯上升使進(jìn)油口與出油口相通，使液壓缸2運(yùn)動(dòng)。

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開大或關(guān)小、提高了對閥芯控制的靈敏度，即提高了穩(wěn)壓精度。
