減溫減壓裝置安裝

1、在本(ben)裝置(zhi)的進出口處應裝有(you)閘閥，供啟(qi)閉(bi)用(yong)。

2、在(zai)(zai)安(an)全閥處下部須(xu)設一固定支架(jia)，在(zai)(zai)裝置(zhi)(zhi)兩端的適當位(wei)置(zhi)(zhi)處應各設一滑動支架(jia)。在(zai)(zai)蒸汽出口處適當位(wei)置(zhi)(zhi)的低點須(xu)裝設疏(shu)水(shui)器(qi)。 閘閥、支架(jia)、補償措施、疏(shu)水(shui)器(qi)等由用戶根據現場情(qing)況(kuang)自行配置(zhi)(zhi)。

3、安裝各閥門(men)時須(xu)注意(yi)蒸汽和(he)減(jian)溫水的流向。

4、安裝完畢(bi)后，須將(jiang)整個管道進(jin)行吹掃，然后進(jin)行水壓(ya)試(shi)驗。試(shi)驗壓(ya)力為工作壓(ya)力的1.5倍.水壓(ya)試(shi)驗時須將(jiang)安全(quan)閥(fa)卸下，用悶板密(mi)封，保(bao)壓(ya)時間不少于五分鐘。

減溫減壓(ya)裝置的特點(dian)，如下：

1、減壓(ya)(ya)系統采用雙閥座減壓(ya)(ya)閥結構，不平衡力小(xiao)，調節范圍大(da)，動作平穩，無卡阻現象。

2、減(jian)壓系統和減(jian)溫系統分開，主要(yao)用于工況惡劣， 如蒸(zheng)汽流(liu)量(liang)小(xiao)不適用采用減(jian)溫減(jian)壓閥的。

減(jian)(jian)(jian)壓(ya)的(de)(de)道理目前廣泛采用的(de)(de)一般(ban)還都是(shi)節流的(de)(de)方法，即在管道上安裝(zhuang)(zhuang)調節門(men)，減(jian)(jian)(jian)溫(wen)減(jian)(jian)(jian)壓(ya)裝(zhuang)(zhuang)置生產廠家，根據減(jian)(jian)(jian)壓(ya)后(hou)所要求(qiu)的(de)(de)壓(ya)力，調節調整門(men)開度的(de)(de)大小，通過這種節制流量(liang)的(de)(de)辦法過到減(jian)(jian)(jian)壓(ya)的(de)(de)目的(de)(de)。有(you)的(de)(de)減(jian)(jian)(jian)溫(wen)減(jian)(jian)(jian)壓(ya)器減(jian)(jian)(jian)溫(wen)和減(jian)(jian)(jian)壓(ya)裝(zhuang)(zhuang)置有(you)一定(ding)距(ju)離，外(wai)觀看來(lai)很清楚，減(jian)(jian)(jian)溫(wen)減(jian)(jian)(jian)壓(ya)裝(zhuang)(zhuang)置哪家好，有(you)的(de)(de)把(ba)減(jian)(jian)(jian)溫(wen)和減(jian)(jian)(jian)壓(ya)設在一起了(le)，外(wai)觀看起來(lai)就不太(tai)好理解了(le)，注意(yi)無論是(shi)哪種，減(jian)(jian)(jian)溫(wen)減(jian)(jian)(jian)壓(ya)裝(zhuang)(zhuang)置原(yuan)理，都是(shi)先(xian)減(jian)(jian)(jian)壓(ya)后(hou)減(jian)(jian)(jian)溫(wen)的(de)(de)。
