全電子式電動(dòng)執(zhí)行器，采用機(jī)電一體化結(jié)構(gòu)，具有機(jī)內(nèi)伺服操作和開度信號(hào)位置反饋、位置指示、手動(dòng)操作等功能，功能強(qiáng)、性能可靠、連線簡單、調(diào)節(jié)精度高，以直行程輸出的推力改變閥門開度位移，達(dá)到對(duì)流體介質(zhì)的工藝參數(shù)精確調(diào)節(jié)控制2.三通調(diào)節(jié)閥按作用模式可分；正作用：電閉式（當(dāng)電信號(hào)增大時(shí)閥位向下位移），《B型》反作用：電開式（當(dāng)電信號(hào)增大時(shí)閥位向上位移），《K型》3.電動(dòng)三通調(diào)節(jié)閥閥芯結(jié)構(gòu)為圓筒型薄壁窗口形閥芯，采用閥芯側(cè)面導(dǎo)向與閥座內(nèi)表面導(dǎo)向和上襯套導(dǎo)向，因此導(dǎo)向面積大，工作可靠。流體對(duì)閥芯作用方向都處于流開狀態(tài)，故閥工作性能穩(wěn)定。4.三通調(diào)節(jié)閥有三通合流式調(diào)節(jié)閥（把兩種流體經(jīng)三通閥混合成一種流體）和三通分流式調(diào)節(jié)閥（把一種流體經(jīng)三通閥分成兩路流出）兩種形式。當(dāng)公稱通徑DN≤80mm和壓差較小的場合時(shí)，分流閥可以采用同口徑的合流閥代替。流量特性有直線性、拋物線性兩種。5.三通調(diào)節(jié)閥它可以代替二臺(tái)同時(shí)使用的二通調(diào)節(jié)閥，起分流或合流作用及兩相調(diào)節(jié)配比作用。本系列產(chǎn)品廣泛應(yīng)用于化工、石油、冶金、電站、輕紡、造紙和制藥等工業(yè)生產(chǎn)過程的自動(dòng)化調(diào)節(jié)和遠(yuǎn)程控制。產(chǎn)品壓力等級(jí)有；公稱通徑DN25——300mm。</p><p>
