減(jian)(jian)(jian)溫(wen)(wen)減(jian)(jian)(jian)壓裝置的工作(zuo)原理(li)：減(jian)(jian)(jian)溫(wen)(wen)減(jian)(jian)(jian)壓裝置的結構形式很多，但無論其形式如何，一(yi)般(ban)都由降溫(wen)(wen)系(xi)(xi)(xi)統(tong)(tong)、減(jian)(jian)(jian)壓系(xi)(xi)(xi)統(tong)(tong)（或降溫(wen)(wen)減(jian)(jian)(jian)壓系(xi)(xi)(xi)統(tong)(tong)）和主蒸汽管體、安全保護系(xi)(xi)(xi)統(tong)(tong)、熱控(kong)系(xi)(xi)(xi)統(tong)(tong)等(deng)幾(ji)部分組(zu)成(cheng)。減(jian)(jian)(jian)溫(wen)(wen)減(jian)(jian)(jian)壓裝置的結構部件由減(jian)(jian)(jian)壓閥、節流孔(kong)、混汽管（帶(dai)噴嘴）、安全閥、供水 調(diao)節(jie)閥、節(jie)流閥、截止閥、止回閥、減(jian)壓水管、法(fa)蘭、標準件等。
1、降(jiang)溫系統：冷(leng)卻(que)水通過高壓(ya)差調節閥（或(huo)變頻水泵等）從不(bu)同形(xing)式的(de)(de)噴嘴以(yi)霧狀噴入文丘里(li)管(guan)或(huo)蒸(zheng)(zheng)汽(qi)管(guan)的(de)(de)蒸(zheng)(zheng)汽(qi)中，以(yi)降(jiang)低蒸(zheng)(zheng)汽(qi)溫度。
2、減(jian)壓(ya)(ya)系統：由減(jian)壓(ya)(ya)閥和孔板組(zu)成。減(jian)壓(ya)(ya)閥通過改變流(liu)通面積來達到調節壓(ya)(ya)力(li)的目的。
3、降溫減(jian)(jian)壓(ya)系(xi)統(tong)：降溫系(xi)統(tong)和減(jian)(jian)壓(ya)系(xi)統(tong)合二為一，減(jian)(jian)小了減(jian)(jian)溫減(jian)(jian)壓(ya)裝置的整體(ti)尺(chi)寸，增(zeng)加了技術復雜度。
4、主蒸(zheng)汽管體：由混合管和蒸(zheng)汽管組成。根據用(yong)戶(hu)(hu)提(ti)供的(de)(de)(de)參數確定，是(shi)減溫(wen)減壓裝置的(de)(de)(de)主要設備(bei)，目(mu)的(de)(de)(de)是(shi)將降溫(wen)減壓后(hou)的(de)(de)(de)蒸(zheng)汽送入用(yong)戶(hu)(hu)所需的(de)(de)(de)管道中。
5、減(jian)(jian)溫減(jian)(jian)壓裝置安全(quan)系統：為防止二次蒸(zheng)汽壓力超過規定(ding)值，自動(dong)開啟安全(quan)閥排出多余蒸(zheng)汽，從而(er)達到減(jian)(jian)壓和安全(quan)保(bao)護的(de)功能(neng)。
減壓(ya)系統采用雙閥座減壓(ya)閥結構(gou)，不(bu)平衡(heng)力小，調節范圍大，動作(zuo)平穩，無卡阻。 減(jian)(jian)(jian)溫(wen)(wen)系(xi)統(tong)采用文(wen)丘(qiu)里管式噴(pen)嘴(zui)方(fang)式，無(wu)傳動部(bu)件(jian)，減(jian)(jian)(jian)溫(wen)(wen)水霧(wu)(wu)化效(xiao)果好(hao)，噴(pen)嘴(zui)拆裝方(fang)便(bian)，減(jian)(jian)(jian)溫(wen)(wen)減(jian)(jian)(jian)壓裝置(zhi)維修方(fang)便(bian)。減(jian)(jian)(jian)壓系(xi)統(tong)與減(jian)(jian)(jian)溫(wen)(wen)系(xi)統(tong)分離，主要用于惡劣工況，如(ru)蒸汽流量(liang)低，不適合使用減(jian)(jian)(jian)溫(wen)(wen)減(jian)(jian)(jian)壓閥，飽和蒸汽（低壓）工況。減(jian)(jian)(jian)溫(wen)(wen)減(jian)(jian)(jian)壓裝置(zhi)主要采用文(wen)丘(qiu)里管減(jian)(jian)(jian)溫(wen)(wen)方(fang)式，減(jian)(jian)(jian)溫(wen)(wen)水充(chong)分霧(wu)(wu)化，達到(dao)更好(hao)的(de)減(jian)(jian)(jian)溫(wen)(wen)效(xiao)果
