減(jian)(jian)(jian)溫(wen)減(jian)(jian)(jian)壓(ya)裝置的工(gong)作(zuo)原理：減(jian)(jian)(jian)溫(wen)減(jian)(jian)(jian)壓(ya)裝置的結構形式(shi)(shi)很多(duo)，但無論其形式(shi)(shi)如何，一般都(dou)由(you)降溫(wen)系(xi)統、減(jian)(jian)(jian)壓(ya)系(xi)統（或(huo)降溫(wen)減(jian)(jian)(jian)壓(ya)系(xi)統）和主蒸汽(qi)管(guan)體(ti)、安全保護系(xi)統、熱控系(xi)統等(deng)幾部分組成(cheng)。減(jian)(jian)(jian)溫(wen)減(jian)(jian)(jian)壓(ya)裝置的結構部件由(you)減(jian)(jian)(jian)壓(ya)閥(fa)(fa)、節流孔、混汽(qi)管(guan)（帶噴嘴）、安全閥(fa)(fa)、供水 調(diao)節(jie)閥、節(jie)流閥、截止閥、止回閥、減壓水管(guan)、法蘭、標準件等。
1、降溫系統：冷卻水通過高壓(ya)差調節閥（或變頻水泵(beng)等(deng)）從不同形式的(de)噴(pen)嘴以霧狀噴(pen)入(ru)文(wen)丘里(li)管或蒸汽管的(de)蒸汽中，以降低蒸汽溫度。
2、減(jian)(jian)(jian)壓(ya)系統：由減(jian)(jian)(jian)壓(ya)閥和(he)孔板(ban)組(zu)成。減(jian)(jian)(jian)壓(ya)閥通(tong)(tong)過改變流(liu)通(tong)(tong)面(mian)積來達到調節壓(ya)力的(de)(de)目的(de)(de)。
3、降溫(wen)減(jian)(jian)壓(ya)(ya)系統(tong)(tong)：降溫(wen)系統(tong)(tong)和減(jian)(jian)壓(ya)(ya)系統(tong)(tong)合二為(wei)一，減(jian)(jian)小了減(jian)(jian)溫(wen)減(jian)(jian)壓(ya)(ya)裝置的整體尺寸，增(zeng)加了技術復雜度。
4、主蒸(zheng)汽(qi)(qi)管(guan)(guan)體：由混合管(guan)(guan)和(he)蒸(zheng)汽(qi)(qi)管(guan)(guan)組成。根據用戶提供(gong)的(de)(de)參數確(que)定，是減(jian)溫減(jian)壓裝(zhuang)置的(de)(de)主要設備，目的(de)(de)是將降溫減(jian)壓后的(de)(de)蒸(zheng)汽(qi)(qi)送入(ru)用戶所需的(de)(de)管(guan)(guan)道中(zhong)。
5、減(jian)溫減(jian)壓(ya)(ya)裝置(zhi)安全(quan)系統：為防(fang)止二次蒸汽壓(ya)(ya)力超過規(gui)定值，自(zi)動開啟安全(quan)閥排出(chu)多余蒸汽，從而(er)達到減(jian)壓(ya)(ya)和安全(quan)保護(hu)的功能。
減(jian)壓(ya)系統(tong)采用雙(shuang)閥座減(jian)壓(ya)閥結構，不平(ping)衡(heng)力小，調節范圍大，動作平(ping)穩，無卡阻。 減(jian)(jian)(jian)(jian)溫(wen)系(xi)(xi)統(tong)采用(yong)文(wen)丘里(li)管式(shi)(shi)噴嘴方式(shi)(shi)，無傳動部件，減(jian)(jian)(jian)(jian)溫(wen)水霧化效(xiao)果好(hao)，噴嘴拆(chai)裝方便，減(jian)(jian)(jian)(jian)溫(wen)減(jian)(jian)(jian)(jian)壓裝置維(wei)修方便。減(jian)(jian)(jian)(jian)壓系(xi)(xi)統(tong)與減(jian)(jian)(jian)(jian)溫(wen)系(xi)(xi)統(tong)分(fen)(fen)離，主要用(yong)于惡劣工況，如蒸汽(qi)流量(liang)低(di)(di)，不適合使用(yong)減(jian)(jian)(jian)(jian)溫(wen)減(jian)(jian)(jian)(jian)壓閥，飽(bao)和蒸汽(qi)（低(di)(di)壓）工況。減(jian)(jian)(jian)(jian)溫(wen)減(jian)(jian)(jian)(jian)壓裝置主要采用(yong)文(wen)丘里(li)管減(jian)(jian)(jian)(jian)溫(wen)方式(shi)(shi)，減(jian)(jian)(jian)(jian)溫(wen)水充分(fen)(fen)霧化，達到更好(hao)的減(jian)(jian)(jian)(jian)溫(wen)效(xiao)果
