②. 蒸汽(qi)伴(ban)熱系統分配站。
配(pei)管(guan)(guan)設(she)計見圖13.4。蒸(zheng)(zheng)汽(qi)(qi)(qi)分(fen)配(pei)站(zhan)(zhan)(zhan)安裝位置高于蒸(zheng)(zheng)汽(qi)(qi)(qi)總(zong)(zong)管(guan)(guan)時，分(fen)配(pei)站(zhan)(zhan)(zhan)低(di)點(dian)可不設(she)排放冷凝水(shui)的(de)蒸(zheng)(zheng)汽(qi)(qi)(qi)疏(shu)水(shui)閥系(xi)統，水(shui)平安裝的(de)分(fen)配(pei)站(zhan)(zhan)(zhan)應(ying)無袋(dai)形并坡向蒸(zheng)(zheng)汽(qi)(qi)(qi)總(zong)(zong)管(guan)(guan)。蒸(zheng)(zheng)汽(qi)(qi)(qi)分(fen)配(pei)站(zhan)(zhan)(zhan)低(di)于蒸(zheng)(zheng)汽(qi)(qi)(qi)總(zong)(zong)管(guan)(guan)時，其上游不得(de)有(you)下凹的(de)袋(dai)形彎，分(fen)配(pei)站(zhan)(zhan)(zhan)的(de)低(di)點(dian)應(ying)設(she)蒸(zheng)(zheng)汽(qi)(qi)(qi)疏(shu)水(shui)閥組。蒸(zheng)(zheng)汽(qi)(qi)(qi)分(fen)配(pei)站(zhan)(zhan)(zhan)至少(shao)有(you)3根伴(ban)管(guan)(guan)（DN15）送(song)至半徑為3m范圍內(nei)的(de)地點(dian)時才(cai)設(she)置，否則伴(ban)熱供(gong)汽(qi)(qi)(qi)管(guan)(guan)可直(zhi)接從(cong)蒸(zheng)(zheng)汽(qi)(qi)(qi)總(zong)(zong)管(guan)(guan)上引出。分(fen)配(pei)站(zhan)(zhan)(zhan)應(ying)布置在(zai)不妨(fang)礙通行、便(bian)于操作(zuo)的(de)地方(fang)，布置應(ying)考慮整齊和美觀。供(gong)汽(qi)(qi)(qi)管(guan)(guan)的(de)閥門應(ying)布置在(zai)便(bian)于接近的(de)地方(fang)。分(fen)配(pei)站(zhan)(zhan)(zhan)的(de)蒸(zheng)(zheng)汽(qi)(qi)(qi)應(ying)從(cong)蒸(zheng)(zheng)汽(qi)(qi)(qi)總(zong)(zong)管(guan)(guan)的(de)頂部(bu)引出。
③. 蒸汽伴熱(re)系(xi)統冷(leng)凝水(shui)回(hui)收(shou)時(shi)，收(shou)集(ji)站和(he)(he)冷(leng)凝水(shui)回(hui)收(shou)管(guan)(guan)的布(bu)置(zhi)，見圖13.5。冷(leng)凝水(shui)收(shou)集(ji)站高于冷(leng)凝水(shui)總(zong)(zong)(zong)管(guan)(guan)時(shi)，低點可(ke)不設排液口(kou)；回(hui)水(shui)管(guan)(guan)應(ying)無袋形并坡向冷(leng)凝水(shui)總(zong)(zong)(zong)管(guan)(guan)。冷(leng)凝水(shui)收(shou)集(ji)站至(zhi)少有(you)3根冷(leng)凝水(shui)支管(guan)(guan)時(shi)才(cai)設置(zhi)，否則可(ke)直(zhi)接(jie)接(jie)至(zhi)冷(leng)凝水(shui)總(zong)(zong)(zong)管(guan)(guan)上。冷(leng)凝水(shui)收(shou)集(ji)站應(ying)布(bu)置(zhi)在不妨礙通行，便(bian)于操(cao)作的地(di)方，布(bu)置(zhi)應(ying)考慮整齊和(he)(he)美觀。冷(leng)凝水(shui)回(hui)水(shui)管(guan)(guan)的閥門應(ying)布(bu)置(zhi)在便(bian)于接(jie)近(jin)的地(di)方。冷(leng)凝水(shui)回(hui)水(shui)管(guan)(guan)應(ying)從(cong)冷(leng)凝水(shui)總(zong)(zong)(zong)管(guan)(guan)的頂部引入。
④. 蒸汽伴熱(re)系(xi)統冷(leng)(leng)凝水不回收時(shi)，收集站(zhan)和(he)冷(leng)(leng)凝水回收管的布置，見圖13.6。
