FESTO減壓閥LR-1/4-D-I-MIDID產(chǎn)品詳情：

減壓閥的壓力為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(jìn)行調(diào)節(jié)。順時(shí)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(kāi)度使P2增大。若反時(shí)針旋轉(zhuǎn)旋鈕1，閥口10的開(kāi)度減小，P2隨之減小。

若P1瞬時(shí)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(lái)力的平衡，使膜片5向上移動(dòng)，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(shí)，因復(fù)位彈簧9的作用，使閥芯8也向上移動(dòng)，關(guān)小進(jìn)氣閥口10，節(jié)流作用加大，使輸出壓力下降，直至達(dá)到新的平衡為止，輸出壓力基本又回到原來(lái)值。若輸入壓力瞬時(shí)下降，輸出壓力也下降、膜片5下移，閥芯8隨之下移，進(jìn)氣閥口10開(kāi)大，節(jié)流作用減小，使輸出壓力也基本回到原來(lái)值。逆時(shí)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(jìn)氣閥口10。再旋轉(zhuǎn)旋鈕1，進(jìn)氣閥芯8的頂端與溢流閥座4將脫開(kāi)，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(wú)輸出狀態(tài)。
