減壓閥是氣動調(diào)節(jié)閥的一個*配件,，主要作用是將氣源的壓力減 減壓閥
壓并穩(wěn)定到一個定值，以便于調(diào)節(jié)閥能夠獲得穩(wěn)定的氣源動力用于調(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,。
（一）直動式減壓閥工作原理
直動式減壓閥所示為直動式帶溢流閥的減壓閥（簡稱溢流減壓閥）的結(jié)構(gòu)圖,。 壓力為P1的壓縮空氣，由左端輸入經(jīng)閥口10節(jié)流后,，壓力降為P2輸出,。P2的大小可由調(diào)壓彈簧2、3進行調(diào)節(jié),。順時針旋轉(zhuǎn)旋鈕1,，壓縮彈簧2、3及膜片5使閥芯8下移,，增大閥口10的開度使P2增大,。若反時針旋轉(zhuǎn)旋鈕1，閥口10的開度減小,，P2隨之減小,。 若P1瞬時升高，P2將隨之升高,，使膜片氣室6內(nèi)壓力升高,，在膜片5上產(chǎn)生的推力相應(yīng)增大，此推力破壞了原來力的平衡,，使膜片5向上移動,，有少部分氣流經(jīng)溢流孔12、排氣孔11排出,。在膜片上移的同時,，因復(fù)位彈簧9的作用，使閥芯8也向上移動,，關(guān)小進氣閥口10,，節(jié)流作用加大，使輸出壓力下降,，直至達到新的平衡為止,，輸出壓力基本又回到原來值。若輸入壓力瞬時下降,，輸出壓力也下降,、膜片5下移，閥芯8隨之下移,，進氣閥口10開大,，節(jié)流作用減小，使輸出壓力也基本回到原來值,。逆時針旋轉(zhuǎn)旋鈕1,。使調(diào)節(jié)彈簧2、3放松,，氣體作用在膜片5上的推力大于調(diào)壓彈簧的作用力,，膜片向上曲，靠復(fù)位彈簧的作用關(guān)閉進氣閥口10,。再旋轉(zhuǎn)旋鈕1,，進氣閥芯8的頂端與溢流閥座4將脫開，膜片氣室6中的壓縮空氣便經(jīng)溢流孔12,、排氣孔11排出,，使閥處于無輸出狀態(tài)。 總之，溢流減壓閥是靠進氣口的節(jié)流作用減壓,，靠膜片上力的平衡作 減壓閥
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）,。
