過濾調(diào)壓閥是按力平衡原理設(shè)計(jì)工作的,其工作原理是按力平衡原理設(shè)計(jì)和工作的。高壓介質(zhì)通過一個(gè)小孔充到一個(gè)相對(duì)較大的腔里實(shí)現(xiàn)減壓,實(shí)際上是靠截流減壓,膜片或活塞的兩面一面是出口腔,一面是人為給的壓力,并且控制小孔大小的閥桿和膜片(活塞)相連,這樣只要給一個(gè)固定的壓力,那么出口腔的壓力就會(huì)一直等于這個(gè)壓力,這個(gè)認(rèn)為給定的壓力可以有彈簧或氣源或液壓源來提供。
具體來說,當(dāng)通入波紋管的信號(hào)壓力增加時(shí),使杠桿繞支點(diǎn)轉(zhuǎn)動(dòng),檔板靠近噴嘴,噴嘴背壓經(jīng)放大器放大后,送入薄膜執(zhí)行機(jī)構(gòu)氣室,使閥桿向下移動(dòng),并帶動(dòng)反饋桿(擺桿)繞支點(diǎn)轉(zhuǎn)動(dòng),連接在同一軸上的反饋凸輪(偏心凸輪)也跟著作逆時(shí)針方向轉(zhuǎn)動(dòng),通過滾輪使杠桿繞支點(diǎn)轉(zhuǎn)動(dòng),并將反饋彈簧拉伸、彈簧對(duì)杠桿的拉力與信號(hào)壓力作用在波紋管上的力達(dá)到力矩平衡時(shí)儀表達(dá)到平衡狀態(tài)。此時(shí),一定的信號(hào)壓力就與一定的閥門位置相對(duì)應(yīng)。
壓力為P1的壓縮空氣,由左端輸入經(jīng)閥口節(jié)流后,壓力降為P2輸出。P2的大小可由主調(diào)壓彈簧進(jìn)行調(diào)節(jié)。拉起并順時(shí)針旋轉(zhuǎn)主調(diào)壓旋鈕,主調(diào)壓彈簧被壓縮,推動(dòng)膜片組合和調(diào)壓柱下移,推動(dòng)閥芯,增大閥口開度使P2增大。出口壓力氣體經(jīng)反饋導(dǎo)管進(jìn)入膜片室,在膜片組合上產(chǎn)生一個(gè)向上推力。當(dāng)此推力與主調(diào)壓彈簧力平衡時(shí),出口壓力便穩(wěn)定在一定值。若反時(shí)針旋轉(zhuǎn)主調(diào)壓旋鈕,閥口的開度減小,P2隨之減小。
