德寶德2731型氣動(dòng)膜片調(diào)節(jié)閥的歷史可追溯到自力式調(diào)壓閥，它包括一個(gè)帶有重物桿的球形閥，重物用來平衡閥芯力，從而得到某種程度的調(diào)節(jié)，另一種早期的自力式調(diào)壓閿?shù)男问绞菈毫ζ胶馐秸{(diào)壓閥。工藝過程的壓力用管線接到彈簧薄膜調(diào)壓閥的薄膜氣室上。無論是減壓閥、閥后壓力式調(diào)壓閥或是差壓調(diào)壓閥都筆夠從這種基型閥門的變更而制造出來。
氣動(dòng)變送器和調(diào)節(jié)器的出現(xiàn)，就必然地導(dǎo)致氣動(dòng)詞節(jié)閥的應(yīng)用。它們本質(zhì)上是減壓閥或閥后壓力式調(diào)壓閥，改用儀表壓縮空氣來代替工藝過程的流體?，F(xiàn)在許多生產(chǎn)減壓閥的公司已經(jīng)發(fā)展成為調(diào)節(jié)閥制造廠。調(diào)節(jié)閥的應(yīng)用從數(shù)量上和復(fù)雜性方面繼續(xù)不斷地得到發(fā)展，許多閥門的閥體和附件的改進(jìn)可以用來解決各種各樣的問題。本手冊的意圖是使工程們熟悉調(diào)節(jié)閥的結(jié)紙醉金迷和因素，幫助儀表工程師在應(yīng)用中選用的閥體、執(zhí)行機(jī)構(gòu)和附件。
德寶德2731型氣動(dòng)膜片調(diào)節(jié)閥屬于控制閥系列，主要作用是調(diào)節(jié)介質(zhì)的壓力、流量、溫度等等參數(shù)，是工藝環(huán)路中zui終的控制元件。調(diào)節(jié)閥按行程特點(diǎn)可分為：直行程和角行程。直行程包括：單座閥、雙座閥、套筒閥、角形閥、三通閥、隔膜閥；角行程包括：蝶閥、球閥、偏心旋轉(zhuǎn)閥、全功能超輕型調(diào)節(jié)閥。調(diào)節(jié)閥按驅(qū)動(dòng)方式可分為：
