減(jian)溫減(jian)壓(ya)(ya)裝置的工作原理：減(jian)溫減(jian)壓(ya)(ya)裝置的結構(gou)形(xing)式(shi)很多，但(dan)無論其形(xing)式(shi)如(ru)何，一(yi)般都由降(jiang)溫系(xi)統(tong)、減(jian)壓(ya)(ya)系(xi)統(tong)（或降(jiang)溫減(jian)壓(ya)(ya)系(xi)統(tong)）和主(zhu)蒸汽管體、安(an)全(quan)保護系(xi)統(tong)、熱控系(xi)統(tong)等幾部分(fen)組成。減(jian)溫減(jian)壓(ya)(ya)裝置的結構(gou)部件由減(jian)壓(ya)(ya)閥、節流孔、混(hun)汽管（帶噴嘴）、安(an)全(quan)閥、供水 調(diao)節閥(fa)、節流閥(fa)、截止閥(fa)、止回閥(fa)、減壓(ya)水管、法蘭、標(biao)準件等(deng)。
1、降溫(wen)系(xi)統：冷卻水(shui)通過高(gao)壓差調節閥（或(huo)變頻水(shui)泵等(deng)）從不(bu)同(tong)形式的噴嘴以霧狀噴入文丘里管(guan)(guan)或(huo)蒸(zheng)(zheng)汽管(guan)(guan)的蒸(zheng)(zheng)汽中，以降低蒸(zheng)(zheng)汽溫(wen)度(du)。
2、減壓(ya)系(xi)統(tong)：由減壓(ya)閥和孔板組成。減壓(ya)閥通過改變流通面(mian)積來(lai)達到調節壓(ya)力的目的。
3、降(jiang)溫減壓系統：降(jiang)溫系統和減壓系統合二為一，減小(xiao)了減溫減壓裝置的整體(ti)尺寸，增(zeng)加了技(ji)術復(fu)雜(za)度。
4、主蒸汽(qi)(qi)管體：由(you)混合管和蒸汽(qi)(qi)管組(zu)成(cheng)。根據用戶提(ti)供的(de)參數確定，是(shi)減溫(wen)減壓裝置的(de)主要設備，目(mu)的(de)是(shi)將降(jiang)溫(wen)減壓后的(de)蒸汽(qi)(qi)送(song)入用戶所需的(de)管道中。
5、減(jian)溫減(jian)壓裝置(zhi)安(an)(an)全系統(tong)：為防止二次蒸(zheng)汽(qi)壓力超過規定值，自動開(kai)啟安(an)(an)全閥排出多余蒸(zheng)汽(qi)，從而(er)達到減(jian)壓和安(an)(an)全保護的功能。
減壓系統采用(yong)雙(shuang)閥座減壓閥結(jie)構，不平衡力小，調節范(fan)圍大，動作(zuo)平穩，無卡阻。 減(jian)(jian)(jian)溫(wen)(wen)(wen)系統(tong)采(cai)用(yong)文丘(qiu)里管(guan)式噴嘴方(fang)式，無(wu)傳(chuan)動部件，減(jian)(jian)(jian)溫(wen)(wen)(wen)水霧(wu)化效(xiao)果好，噴嘴拆(chai)裝方(fang)便(bian)，減(jian)(jian)(jian)溫(wen)(wen)(wen)減(jian)(jian)(jian)壓(ya)裝置(zhi)維修方(fang)便(bian)。減(jian)(jian)(jian)壓(ya)系統(tong)與減(jian)(jian)(jian)溫(wen)(wen)(wen)系統(tong)分離，主要(yao)用(yong)于惡劣工況，如蒸汽(qi)流量低，不(bu)適合使用(yong)減(jian)(jian)(jian)溫(wen)(wen)(wen)減(jian)(jian)(jian)壓(ya)閥，飽(bao)和蒸汽(qi)（低壓(ya)）工況。減(jian)(jian)(jian)溫(wen)(wen)(wen)減(jian)(jian)(jian)壓(ya)裝置(zhi)主要(yao)采(cai)用(yong)文丘(qiu)里管(guan)減(jian)(jian)(jian)溫(wen)(wen)(wen)方(fang)式，減(jian)(jian)(jian)溫(wen)(wen)(wen)水充分霧(wu)化，達到更好的減(jian)(jian)(jian)溫(wen)(wen)(wen)效(xiao)果
