2. 蒸汽(qi)伴熱系統（圖13.3）
②. 蒸汽伴熱系統分(fen)配站。
配(pei)(pei)(pei)管(guan)(guan)設計(ji)見(jian)圖13.4。蒸(zheng)(zheng)汽(qi)(qi)(qi)(qi)分(fen)配(pei)(pei)(pei)站(zhan)安裝位置高(gao)于(yu)蒸(zheng)(zheng)汽(qi)(qi)(qi)(qi)總管(guan)(guan)時(shi)(shi)，分(fen)配(pei)(pei)(pei)站(zhan)低點(dian)可不設排放冷凝水(shui)的(de)蒸(zheng)(zheng)汽(qi)(qi)(qi)(qi)疏水(shui)閥系統，水(shui)平安裝的(de)分(fen)配(pei)(pei)(pei)站(zhan)應(ying)無袋形并(bing)坡向蒸(zheng)(zheng)汽(qi)(qi)(qi)(qi)總管(guan)(guan)。蒸(zheng)(zheng)汽(qi)(qi)(qi)(qi)分(fen)配(pei)(pei)(pei)站(zhan)低于(yu)蒸(zheng)(zheng)汽(qi)(qi)(qi)(qi)總管(guan)(guan)時(shi)(shi)，其上游不得有下凹(ao)的(de)袋形彎，分(fen)配(pei)(pei)(pei)站(zhan)的(de)低點(dian)應(ying)設蒸(zheng)(zheng)汽(qi)(qi)(qi)(qi)疏水(shui)閥組。蒸(zheng)(zheng)汽(qi)(qi)(qi)(qi)分(fen)配(pei)(pei)(pei)站(zhan)至(zhi)少有3根(gen)伴管(guan)(guan)（DN15）送至(zhi)半徑(jing)為(wei)3m范圍內的(de)地點(dian)時(shi)(shi)才設置，否則伴熱(re)供汽(qi)(qi)(qi)(qi)管(guan)(guan)可直(zhi)接從蒸(zheng)(zheng)汽(qi)(qi)(qi)(qi)總管(guan)(guan)上引出。分(fen)配(pei)(pei)(pei)站(zhan)應(ying)布(bu)置在不妨礙(ai)通(tong)行、便(bian)于(yu)操作的(de)地方，布(bu)置應(ying)考慮整齊和美觀。供汽(qi)(qi)(qi)(qi)管(guan)(guan)的(de)閥門應(ying)布(bu)置在便(bian)于(yu)接近的(de)地方。分(fen)配(pei)(pei)(pei)站(zhan)的(de)蒸(zheng)(zheng)汽(qi)(qi)(qi)(qi)應(ying)從蒸(zheng)(zheng)汽(qi)(qi)(qi)(qi)總管(guan)(guan)的(de)頂(ding)部引出。
③. 蒸汽(qi)伴熱系統冷(leng)(leng)凝(ning)(ning)水(shui)回(hui)收(shou)(shou)時，收(shou)(shou)集(ji)(ji)站和(he)(he)冷(leng)(leng)凝(ning)(ning)水(shui)回(hui)收(shou)(shou)管(guan)的(de)布置，見圖13.5。冷(leng)(leng)凝(ning)(ning)水(shui)收(shou)(shou)集(ji)(ji)站高于(yu)冷(leng)(leng)凝(ning)(ning)水(shui)總管(guan)時，低點(dian)可不(bu)設排液(ye)口；回(hui)水(shui)管(guan)應(ying)無袋形并坡向冷(leng)(leng)凝(ning)(ning)水(shui)總管(guan)。冷(leng)(leng)凝(ning)(ning)水(shui)收(shou)(shou)集(ji)(ji)站至(zhi)少有(you)3根冷(leng)(leng)凝(ning)(ning)水(shui)支管(guan)時才設置，否(fou)則可直接(jie)接(jie)至(zhi)冷(leng)(leng)凝(ning)(ning)水(shui)總管(guan)上。冷(leng)(leng)凝(ning)(ning)水(shui)收(shou)(shou)集(ji)(ji)站應(ying)布置在不(bu)妨(fang)礙通行(xing)，便(bian)于(yu)操作(zuo)的(de)地(di)(di)方，布置應(ying)考慮(lv)整齊和(he)(he)美觀。冷(leng)(leng)凝(ning)(ning)水(shui)回(hui)水(shui)管(guan)的(de)閥門應(ying)布置在便(bian)于(yu)接(jie)近的(de)地(di)(di)方。冷(leng)(leng)凝(ning)(ning)水(shui)回(hui)水(shui)管(guan)應(ying)從冷(leng)(leng)凝(ning)(ning)水(shui)總管(guan)的(de)頂部引入。
④. 蒸汽伴熱系統冷凝(ning)水(shui)不(bu)回收時，收集站和冷凝(ning)水(shui)回收管的(de)布置，見圖13.6。
