減溫(wen)減壓(ya)裝(zhuang)置的工作原(yuan)理：減溫(wen)減壓(ya)裝(zhuang)置的結構形式很多(duo)，但無論其形式如(ru)何，一般都由(you)降(jiang)溫(wen)系(xi)統(tong)、減壓(ya)系(xi)統(tong)（或降(jiang)溫(wen)減壓(ya)系(xi)統(tong)）和主(zhu)蒸汽(qi)(qi)管體(ti)、安全(quan)保(bao)護系(xi)統(tong)、熱控系(xi)統(tong)等(deng)幾部分(fen)組成。減溫(wen)減壓(ya)裝(zhuang)置的結構部件由(you)減壓(ya)閥(fa)、節(jie)流孔(kong)、混汽(qi)(qi)管（帶(dai)噴(pen)嘴）、安全(quan)閥(fa)、供水 調節閥、節流(liu)閥、截止閥、止回閥、減壓水(shui)管(guan)、法蘭(lan)、標準件等。
1、降溫系統：冷卻水(shui)通過高壓(ya)差(cha)調節閥（或(huo)(huo)變(bian)頻水(shui)泵等）從(cong)不同(tong)形(xing)式的噴(pen)嘴以霧狀噴(pen)入文丘(qiu)里管或(huo)(huo)蒸汽(qi)管的蒸汽(qi)中，以降低蒸汽(qi)溫度。
2、減壓(ya)系(xi)統：由(you)減壓(ya)閥和孔板(ban)組(zu)成。減壓(ya)閥通(tong)過改變流(liu)通(tong)面(mian)積來達到調節壓(ya)力的(de)(de)目(mu)的(de)(de)。
3、降溫減(jian)(jian)(jian)(jian)壓(ya)系(xi)(xi)統(tong)(tong)：降溫系(xi)(xi)統(tong)(tong)和減(jian)(jian)(jian)(jian)壓(ya)系(xi)(xi)統(tong)(tong)合二為一，減(jian)(jian)(jian)(jian)小了減(jian)(jian)(jian)(jian)溫減(jian)(jian)(jian)(jian)壓(ya)裝置(zhi)的整體尺(chi)寸(cun)，增加了技術復(fu)雜(za)度。
4、主蒸(zheng)汽管(guan)體：由混合管(guan)和(he)蒸(zheng)汽管(guan)組成。根據用戶提供的(de)參(can)數(shu)確定，是(shi)減溫減壓(ya)裝(zhuang)置的(de)主要設備，目的(de)是(shi)將降(jiang)溫減壓(ya)后的(de)蒸(zheng)汽送入用戶所需的(de)管(guan)道中。
5、減(jian)(jian)溫減(jian)(jian)壓裝置(zhi)安(an)(an)(an)全(quan)系(xi)統：為(wei)防止二次蒸(zheng)汽壓力(li)超過規(gui)定值，自動開啟(qi)安(an)(an)(an)全(quan)閥排出多余蒸(zheng)汽，從而達(da)到減(jian)(jian)壓和安(an)(an)(an)全(quan)保護的功能。
減壓系統采用雙閥座減壓閥結構，不(bu)平(ping)衡力小(xiao)，調節范圍大(da)，動作平(ping)穩(wen)，無卡阻。 減(jian)(jian)(jian)(jian)溫系統(tong)(tong)采用(yong)文丘里(li)管式噴嘴方(fang)(fang)式，無傳動部件(jian)，減(jian)(jian)(jian)(jian)溫水(shui)霧(wu)化效果好，噴嘴拆(chai)裝(zhuang)方(fang)(fang)便(bian)，減(jian)(jian)(jian)(jian)溫減(jian)(jian)(jian)(jian)壓裝(zhuang)置維修方(fang)(fang)便(bian)。減(jian)(jian)(jian)(jian)壓系統(tong)(tong)與減(jian)(jian)(jian)(jian)溫系統(tong)(tong)分(fen)離(li)，主(zhu)要用(yong)于(yu)惡劣(lie)工(gong)況，如蒸汽流量低，不適合使用(yong)減(jian)(jian)(jian)(jian)溫減(jian)(jian)(jian)(jian)壓閥，飽和(he)蒸汽（低壓）工(gong)況。減(jian)(jian)(jian)(jian)溫減(jian)(jian)(jian)(jian)壓裝(zhuang)置主(zhu)要采用(yong)文丘里(li)管減(jian)(jian)(jian)(jian)溫方(fang)(fang)式，減(jian)(jian)(jian)(jian)溫水(shui)充分(fen)霧(wu)化，達到更好的減(jian)(jian)(jian)(jian)溫效果
