安沃馳AVENTICS三位四通氣動閥R417001757

簡單地說是通過壓縮空氣實現(xiàn)的,在實際應(yīng)用中,了解氣動調(diào)節(jié)閥工作原理有很重要的意義。氣動調(diào)節(jié)閥是以壓縮空氣為動力源,以氣缸為執(zhí)行器,并借助于電氣閥門定位器,轉(zhuǎn)換器,電磁閥等附件去驅(qū)動閥門,實現(xiàn)開關(guān)量或比例式調(diào)節(jié),接收工業(yè)自動化控制系統(tǒng)的控制信號來完成調(diào)節(jié)管道介質(zhì)的流量,壓力,溫度等各種工藝參數(shù)。氣動調(diào)節(jié)閥的特點是控制簡單,反應(yīng)快速,本質(zhì)安全,不需要另外采取防爆措施。
氣動調(diào)節(jié)閥動作分氣開型和氣關(guān)型兩種。氣開型（Air to open）是當(dāng)膜頭上空氣壓力增加時,閥門向增加開度方向動作,當(dāng)達(dá)到輸入氣壓上*,閥門處于全開狀態(tài)。反過來,當(dāng)空氣壓力減小時,閥門向關(guān)閉方向動作,在沒有輸入空氣時,閥門全閉。有時,氣開型閥門又稱故障關(guān)閉型（Fail to Close FC）。氣關(guān)型（Air to Close）動作方向正好與氣開型相反。當(dāng)空氣壓力增加時,閥門向關(guān)閉方向動作；空氣壓力減小或沒有時,閥門向開啟方向動作至全開為止。氣動調(diào)節(jié)閥的氣開或氣關(guān),通常是通過執(zhí)行機構(gòu)的正反作用和閥態(tài)結(jié)構(gòu)的不同組裝方式實現(xiàn)。
