style="text-indent:25px">閥門(mén)定位器是由壓縮空氣驅(qū)動(dòng)的閥。它主要由各種類(lèi)型的帶有氣動(dòng)執(zhí)行器的閥組成。閥門(mén)定位器的類(lèi)型很多。由氣動(dòng)源驅(qū)動(dòng)的閥，例如氣動(dòng)調(diào)節(jié)閥，氣動(dòng)球閥和氣動(dòng)蝶閥，都可以稱(chēng)為氣動(dòng)調(diào)節(jié)閥。閥門(mén)定位器配備有不同的附件，具有兩種類(lèi)型的調(diào)節(jié)和切換。氣動(dòng)開(kāi)關(guān)閥依靠電磁閥來(lái)切換氣源以打開(kāi)和關(guān)閉閥門(mén)。它主要用于在工作條件下切割或連接管道介質(zhì)。氣動(dòng)調(diào)節(jié)閥需要配備一個(gè)定位器，以接收控制系統(tǒng)發(fā)送的模擬信號(hào)，例如4-20mA或1-5V。適用于需要調(diào)節(jié)管道介質(zhì)參數(shù)的工作條件。并可以根據(jù)用戶(hù)工作條件的需要選擇氣體開(kāi)放式或氣體封閉式。無(wú)錫市凱爾利科技有限公司。</p><p
