減溫減壓裝置(zhi)按進口壓力和溫度(du)的(de)分(fen)類：

中(zhong)溫(wen)中(zhong)壓(ya)減溫(wen)減壓(ya)裝置(zhi)：

一次蒸(zheng)汽參(can)數（進口蒸(zheng)汽參(can)數）：壓力P1=3，減溫(wen)減壓裝(zhuang)置批發，9MPa； 溫(wen)度t1=450℃壓力；

二次蒸汽參(can)數(shu)（出口蒸汽參(can)數(shu)）：壓力(li)P2由用戶要求確定；溫度t2=飽和溫度；

流量： Q=2～360t/h（噸/小時(shi)）

減(jian)(jian)壓(ya)(ya)系統和(he)(he)減(jian)(jian)溫(wen)(wen)(wen)系統分開，主(zhu)要(yao)用(yong)于(yu)工(gong)況(kuang)惡劣， 如蒸(zheng)(zheng)汽流量小不適(shi)用(yong)采用(yong)減(jian)(jian)溫(wen)(wen)(wen)減(jian)(jian)壓(ya)(ya)閥的，及飽(bao)和(he)(he)蒸(zheng)(zheng)汽的工(gong)況(kuang)(壓(ya)(ya)力(li)較(jiao)(jiao)低主(zhu)要(yao)考(kao)慮(lv)蒸(zheng)(zheng)汽流速較(jiao)(jiao)低)采用(yong)文(wen)丘里管減(jian)(jian)溫(wen)(wen)(wen)方式(shi)，減(jian)(jian)溫(wen)(wen)(wen)水充分霧化，以達到(dao)較(jiao)(jiao)好的減(jian)(jian)溫(wen)(wen)(wen)效果

減溫減壓閥：

高溫(wen)高壓(ya)(ya)蒸(zheng)(zheng)汽(qi)(qi)在一個(ge)閥體內部同(tong)時進(jin)行減(jian)(jian)溫(wen)減(jian)(jian)壓(ya)(ya)，并實現(xian)蒸(zheng)(zheng)汽(qi)(qi)的自(zi)調節。其減(jian)(jian)壓(ya)(ya)件(jian)為多(duo)孔(kong)籠式(shi)結構，減(jian)(jian)溫(wen)減(jian)(jian)壓(ya)(ya)裝置，并有均流(liu)罩(zhao)和(he)節流(liu)孔(kong)板實現(xian)多(duo)級(ji)(ji)減(jian)(jian)壓(ya)(ya)，其減(jian)(jian)壓(ya)(ya)級(ji)(ji)數決(jue)定于蒸(zheng)(zheng)汽(qi)(qi)進(jin)出(chu)口(kou)的壓(ya)(ya)差，每級(ji)(ji)壓(ya)(ya)力約降低(di)一半左右，從而(er)減(jian)(jian)少了節流(liu)件(jian)的磨損，降低(di)了高速汽(qi)(qi)生的振動和(he)噪音。其減(jian)(jian)溫(wen)由(you)配(pei)置在閥內的減(jian)(jian)溫(wen)器完(wan)成，減(jian)(jian)溫(wen)水通過減(jian)(jian)溫(wen)器內設置的機械霧(wu)化噴咀（圓柱形多(duo)孔(kong)噴咀）噴出(chu)，由(you)高溫(wen)蒸(zheng)(zheng)汽(qi)(qi)節流(liu)后的高速汽(qi)(qi)流(liu)將減(jian)(jian)溫(wen)水充分霧(wu)化，減(jian)(jian)溫(wen)減(jian)(jian)壓(ya)(ya)裝置原理，使其迅速與(yu)高溫(wen)蒸(zheng)(zheng)汽(qi)(qi)混(hun)合并快(kuai)速蒸(zheng)(zheng)發為低(di)溫(wen)蒸(zheng)(zheng)汽(qi)(qi)，可避免管(guan)(guan)道內積水而(er)造成水擊(ji)現(xian)象，達到了較好的減(jian)(jian)溫(wen)效(xiao)果。這是與(yu)文(wen)式(shi)管(guan)(guan)減(jian)(jian)溫(wen)器的不同(tong)之處。

減溫減壓(ya)裝置的(de)安(an)全(quan)(quan)保(bao)護(hu)系統：采(cai)用彈簧安(an)全(quan)(quan)閥（或主安(an)全(quan)(quan)閥）來(lai)實現安(an)全(quan)(quan)保(bao)護(hu)。當管道內蒸汽壓(ya)力(li)超過允許值(zhi)時(shi)，安(an)全(quan)(quan)閥即(ji)自動(dong)開啟排(pai)除蒸汽。當壓(ya)力(li)恢復至規定值(zhi)時(shi)，安(an)全(quan)(quan)閥即(ji)自動(dong)關閉。使二(er)次蒸汽壓(ya)力(li)保(bao)持(chi)在允許值(zhi)內，保(bao)證(zheng)設備和管路的(de)安(an)全(quan)(quan)運行。

減(jian)溫(wen)減(jian)壓(ya)裝置的熱(re)力調(diao)節(jie)系統：實(shi)現對(dui)電動(dong)減(jian)溫(wen)減(jian)壓(ya)閥和(he)電動(dong)調(diao)節(jie)閥的控(kong)制，有自動(dong)控(kong)制、遠程遙控(kong)或現場手(shou)動(dong)控(kong)制等多種形(xing)式。
