減(jian)(jian)溫(wen)(wen)減(jian)(jian)壓(ya)(ya)裝置(zhi)的(de)工(gong)作(zuo)原理(li)：減(jian)(jian)溫(wen)(wen)減(jian)(jian)壓(ya)(ya)裝置(zhi)的(de)結構形(xing)式很多(duo)，但無論其(qi)形(xing)式如(ru)何，一(yi)般都(dou)由降(jiang)溫(wen)(wen)系(xi)統(tong)、減(jian)(jian)壓(ya)(ya)系(xi)統(tong)（或降(jiang)溫(wen)(wen)減(jian)(jian)壓(ya)(ya)系(xi)統(tong)）和主蒸(zheng)汽(qi)管體(ti)、安(an)(an)全保護系(xi)統(tong)、熱控系(xi)統(tong)等幾部分組成。減(jian)(jian)溫(wen)(wen)減(jian)(jian)壓(ya)(ya)裝置(zhi)的(de)結構部件由減(jian)(jian)壓(ya)(ya)閥(fa)(fa)、節(jie)流孔、混汽(qi)管（帶(dai)噴嘴）、安(an)(an)全閥(fa)(fa)、供水 調節(jie)閥(fa)、節(jie)流閥(fa)、截止(zhi)閥(fa)、止(zhi)回(hui)閥(fa)、減壓水管、法蘭、標準件等(deng)。
1、降溫(wen)系統：冷卻水(shui)通過(guo)高壓差(cha)調(diao)節閥（或變頻(pin)水(shui)泵等）從(cong)不同形(xing)式的噴嘴以(yi)霧狀噴入文丘(qiu)里管或蒸(zheng)汽(qi)管的蒸(zheng)汽(qi)中，以(yi)降低(di)蒸(zheng)汽(qi)溫(wen)度。
2、減壓(ya)系(xi)統：由(you)減壓(ya)閥(fa)和孔板組成。減壓(ya)閥(fa)通過(guo)改(gai)變流通面積來達到調節(jie)壓(ya)力的目(mu)的。
3、降溫減壓系(xi)統：降溫系(xi)統和減壓系(xi)統合二為(wei)一，減小了減溫減壓裝置(zhi)的整體尺(chi)寸，增加了技術復(fu)雜(za)度。
4、主蒸(zheng)汽(qi)(qi)管體(ti)：由混(hun)合管和蒸(zheng)汽(qi)(qi)管組(zu)成。根據用(yong)戶提(ti)供的(de)(de)參數(shu)確定(ding)，是減(jian)溫(wen)減(jian)壓裝置的(de)(de)主要設備，目的(de)(de)是將降溫(wen)減(jian)壓后的(de)(de)蒸(zheng)汽(qi)(qi)送入(ru)用(yong)戶所(suo)需的(de)(de)管道(dao)中。
5、減(jian)溫(wen)減(jian)壓裝(zhuang)置安全(quan)系(xi)統：為防止(zhi)二次蒸汽壓力超(chao)過規定值，自動開啟安全(quan)閥排(pai)出多余蒸汽，從而達到減(jian)壓和安全(quan)保護的功能。
減壓系(xi)統(tong)采(cai)用雙閥座減壓閥結(jie)構，不平衡力小，調節范圍大(da)，動(dong)作平穩，無(wu)卡阻。 減(jian)(jian)(jian)(jian)溫(wen)(wen)(wen)(wen)(wen)系統采用(yong)文丘里(li)管式噴嘴方(fang)式，無傳動(dong)部(bu)件，減(jian)(jian)(jian)(jian)溫(wen)(wen)(wen)(wen)(wen)水(shui)霧化效果(guo)好，噴嘴拆裝方(fang)便(bian)，減(jian)(jian)(jian)(jian)溫(wen)(wen)(wen)(wen)(wen)減(jian)(jian)(jian)(jian)壓裝置維修(xiu)方(fang)便(bian)。減(jian)(jian)(jian)(jian)壓系統與減(jian)(jian)(jian)(jian)溫(wen)(wen)(wen)(wen)(wen)系統分離，主要用(yong)于惡劣工況，如蒸汽(qi)流量低，不(bu)適合(he)使用(yong)減(jian)(jian)(jian)(jian)溫(wen)(wen)(wen)(wen)(wen)減(jian)(jian)(jian)(jian)壓閥(fa)，飽和蒸汽(qi)（低壓）工況。減(jian)(jian)(jian)(jian)溫(wen)(wen)(wen)(wen)(wen)減(jian)(jian)(jian)(jian)壓裝置主要采用(yong)文丘里(li)管減(jian)(jian)(jian)(jian)溫(wen)(wen)(wen)(wen)(wen)方(fang)式，減(jian)(jian)(jian)(jian)溫(wen)(wen)(wen)(wen)(wen)水(shui)充(chong)分霧化，達到(dao)更好的減(jian)(jian)(jian)(jian)溫(wen)(wen)(wen)(wen)(wen)效果(guo)
