SMC AR系列減壓閥結(jié)構(gòu)原理
下圖是SMC AR平衡式直動(dòng)式減壓閥結(jié)構(gòu)原理圖。閥芯的下部與二次側(cè)壓力相通，故閥芯上下所受氣壓力是平衡的，壓力的變動(dòng)（不論是一次側(cè)還是二次側(cè)）不影響閥芯上下氣壓力的平衡，故這種結(jié)構(gòu)形式的壓力特性好。
SMC膜片式減壓閥的工作原理是：將手輪外拉，見到黃色圈后，順時(shí)針旋轉(zhuǎn)手輪，調(diào)壓彈簧被壓縮，推動(dòng)膜片組件下移，通過(guò)閥桿，打開閥芯，則進(jìn)氣口壓力經(jīng)閥芯節(jié)流降壓，有壓力輸出。出口壓力氣體經(jīng)反饋管浸入膜片下腔，在膜片上產(chǎn)生一個(gè)向上的推力。當(dāng)此推力與調(diào)壓彈簧平衡時(shí)，出口壓力便穩(wěn)定在一定值。
逆時(shí)針旋轉(zhuǎn)手輪，調(diào)壓彈簧力不斷減小，閥芯逐漸關(guān)閉，膜片下腔中的壓縮空氣，經(jīng)溢流閥不斷從排氣孔排處，直至zui后出口壓力降為零。
調(diào)壓完成后，將手輪壓回，手輪被鎖住，以保持設(shè)定壓力一定。故稱為鎖定型手輪。
溢流式減壓閥常用于二次側(cè)負(fù)載變動(dòng)的場(chǎng)合，如進(jìn)行頻繁調(diào)整的場(chǎng)合、二次側(cè)有容器（如氣缸）的場(chǎng)合。在使用過(guò)程中，經(jīng)常要從溢流孔排出少量氣體。當(dāng)介質(zhì)為有害氣體的氣路中，為防止污染工作場(chǎng)所，應(yīng)選用無(wú)溢流孔的減壓閥，即非溢流式減壓閥。非溢流式減壓閥也常用于經(jīng)常耗氣的吹氣系統(tǒng)和氣馬達(dá)。
