差壓節(jié)流裝置的類型（1）孔板 ?孔板是最普遍、最悠久的一種經(jīng)典流量節(jié)流裝置，曾長(zhǎng)期占據(jù)節(jié)流裝置市場(chǎng)的魁首。但目前現(xiàn)場(chǎng)已無(wú)法滿足它所要求現(xiàn)場(chǎng)直管段長(zhǎng)度，制約了其應(yīng)用。（2）多孔孔板 多孔孔板與經(jīng)典孔板相比較最大的特點(diǎn)是：多孔孔板的節(jié)流件除了節(jié)流還有整流的作用，它解決了工業(yè)現(xiàn)場(chǎng)的直管段長(zhǎng)度不長(zhǎng)又要求必要的準(zhǔn)確度的矛盾。在直管段長(zhǎng)度較短（5~10D）的情況下，仍可達(dá)到士1%的準(zhǔn)確度，值得關(guān)注。①發(fā)展歷程 2002年，由美國(guó)Rosemount推出的調(diào)整孔板*4*5，(圖1）首創(chuàng)了這類流量節(jié)流裝置，據(jù)該公司稱：前直管段長(zhǎng)度大于5D情況下，可保持±1%準(zhǔn)確度。2004年美國(guó)A+Flowtek公司推出了平衡式節(jié)流裝置（圖2B），2007年進(jìn)入中國(guó)；2008年我國(guó)天津某公司推出了結(jié)構(gòu)不同于美國(guó)A+Flowtek的整流式節(jié)流裝置（圖2A、C）。而測(cè)試數(shù)據(jù)表明，在前直管段僅2D時(shí)，準(zhǔn)確度可達(dá)±1%，為5D時(shí)，準(zhǔn)確度可達(dá)±0.3%，β值建議取0.5～0.65之間。在前直管段長(zhǎng)度約30D的條件下，對(duì)圖2所示的三種結(jié)構(gòu)進(jìn)行了流出系數(shù)的重復(fù)性、不確定度、線性度的測(cè)試比較，技術(shù)性能難分伯仲。?
