2. 蒸(zheng)汽伴熱系(xi)統(tong)（圖13.3）
②. 蒸汽伴熱系統分配站。
配(pei)(pei)管(guan)(guan)(guan)(guan)(guan)設計見(jian)圖13.4。蒸(zheng)汽(qi)(qi)分(fen)配(pei)(pei)站安裝位置高于(yu)蒸(zheng)汽(qi)(qi)總(zong)管(guan)(guan)(guan)(guan)(guan)時，分(fen)配(pei)(pei)站低(di)點可不設排(pai)放冷凝水(shui)(shui)的(de)(de)蒸(zheng)汽(qi)(qi)疏水(shui)(shui)閥系統，水(shui)(shui)平安裝的(de)(de)分(fen)配(pei)(pei)站應無袋形并(bing)坡(po)向蒸(zheng)汽(qi)(qi)總(zong)管(guan)(guan)(guan)(guan)(guan)。蒸(zheng)汽(qi)(qi)分(fen)配(pei)(pei)站低(di)于(yu)蒸(zheng)汽(qi)(qi)總(zong)管(guan)(guan)(guan)(guan)(guan)時，其上游不得(de)有下(xia)凹(ao)的(de)(de)袋形彎，分(fen)配(pei)(pei)站的(de)(de)低(di)點應設蒸(zheng)汽(qi)(qi)疏水(shui)(shui)閥組。蒸(zheng)汽(qi)(qi)分(fen)配(pei)(pei)站至少有3根伴管(guan)(guan)(guan)(guan)(guan)（DN15）送至半徑為3m范圍內的(de)(de)地(di)點時才設置，否則伴熱供(gong)(gong)汽(qi)(qi)管(guan)(guan)(guan)(guan)(guan)可直(zhi)接(jie)從蒸(zheng)汽(qi)(qi)總(zong)管(guan)(guan)(guan)(guan)(guan)上引出。分(fen)配(pei)(pei)站應布(bu)置在(zai)不妨礙(ai)通(tong)行、便于(yu)操作的(de)(de)地(di)方(fang)，布(bu)置應考慮整齊和美觀。供(gong)(gong)汽(qi)(qi)管(guan)(guan)(guan)(guan)(guan)的(de)(de)閥門(men)應布(bu)置在(zai)便于(yu)接(jie)近的(de)(de)地(di)方(fang)。分(fen)配(pei)(pei)站的(de)(de)蒸(zheng)汽(qi)(qi)應從蒸(zheng)汽(qi)(qi)總(zong)管(guan)(guan)(guan)(guan)(guan)的(de)(de)頂部引出。
③. 蒸(zheng)汽伴熱系統冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)回(hui)(hui)收(shou)(shou)(shou)時，收(shou)(shou)(shou)集(ji)站(zhan)和(he)冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)回(hui)(hui)收(shou)(shou)(shou)管的(de)(de)布(bu)置(zhi)，見圖13.5。冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)收(shou)(shou)(shou)集(ji)站(zhan)高于(yu)冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)總管時，低點可(ke)不(bu)設排液口；回(hui)(hui)水(shui)管應(ying)無(wu)袋形并坡向冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)總管。冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)收(shou)(shou)(shou)集(ji)站(zhan)至(zhi)少(shao)有3根冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)支管時才(cai)設置(zhi)，否(fou)則可(ke)直接接至(zhi)冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)總管上。冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)收(shou)(shou)(shou)集(ji)站(zhan)應(ying)布(bu)置(zhi)在(zai)不(bu)妨礙通(tong)行，便(bian)于(yu)操(cao)作(zuo)的(de)(de)地(di)方，布(bu)置(zhi)應(ying)考慮(lv)整(zheng)齊和(he)美觀。冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)回(hui)(hui)水(shui)管的(de)(de)閥(fa)門應(ying)布(bu)置(zhi)在(zai)便(bian)于(yu)接近的(de)(de)地(di)方。冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)回(hui)(hui)水(shui)管應(ying)從冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)總管的(de)(de)頂部(bu)引入。
④. 蒸汽伴熱系統冷凝水不回(hui)收時，收集站和冷凝水回(hui)收管的(de)布(bu)置，見圖13.6。
