仙童調(diào)節(jié)閥廠家銷售 調(diào)壓閥作用:過濾調(diào)壓閥是用來做什么的?減壓的。氣動(dòng)閥門定位器是按力平衡原理設(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。當(dāng)通入波紋管的信號(hào)壓力增加時(shí),使杠桿2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1繞支點(diǎn)轉(zhuǎn)動(dòng),并將反饋彈簧拉伸、彈簧對(duì)杠桿2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)。以上作用方式為正作用,若要改變作用方式,只要將凸輪翻轉(zhuǎn),A向變成B向等,即可。
