                                                                                                                                  進口氣動三通調節閥主要用于將一股進口流體分成二股出口流體或者把二股進口流體合成一股出口流體。三通閥分為合流調節閥,分流調節閥。閥尺寸,壓差較小時合流閥也可以作為分流閥用。進口氣動三通調節閥采用圓筒型薄壁窗口形閥芯導向,不同于柱塞形閥芯的襯套導向。配用多彈簧執行機構。進口氣動三通調節閥具有結構簡單、重量輕、體積小、拆裝方便等優點。廣泛應用于精確控制氣體、液體等介質,工藝參數如壓力、流量、溫度、液位保持在給定值。

                                                                                                                                  進口氣動三通調節閥產品特點

                                                                                                                                  1、進口氣動三通調節閥是自動化控制系統中儀表的執行單元,采用電-氣閥門定位器,以電信號和壓縮空氣為動力,接受控制系統輸入的0-10mA DC4-20mA DC電流信號,由調節器將壓縮空氣,轉換成氣源壓力信號輸入輸出,可實現分程控制(段幅信號),從而改變閥芯開度位移,達到對流體介質的工藝參數精確調節控制

                                                                                                                                  2、進口氣動三通調節閥按作用模式可分;

                                                                                                                                  正作用:氣閉式(當信號壓力增大時閥位向下位移)

                                                                                                                                  反作用:氣開式(當信號壓力增大時閥位向上位移)

                                                                                                                                  3、三通調節閥閥芯結構為圓筒型薄壁窗口形閥芯,采用閥芯側面導向與閥座內表面導向和上襯套導向,因此導向面積大,工作可靠。流體對閥芯作用方向都處于流開狀態,故閥工作性能穩定。

                                                                                                                                  4、三通調節閥有三通合流式調節閥(把兩種流體經三通閥混合成一種流體)和三通分流式調節閥(把一種流體經三通閥分成兩路流出)兩種形式。當公稱通徑DN80mm和壓差較小的場合時,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、三通調節閥它可以代替二臺同時使用的二通調節閥,起分流或合流作用及兩相調節配比作用。

                                                                                                                                  本系列產品廣泛應用于化工、石油、冶金、電站、輕紡、造紙和制藥等工業生產過程的自動化調節和遠程控制。產品壓力等級有PN1.6 4.0 6.4MPa;公稱通徑DN25~300mm;適用流體溫度有-40~+450℃;按溫度高低配用不同閥蓋可分常溫型、高溫型兩種

                                                                                                                                  進口氣動三通調節閥零件材料
