 2. 蒸汽伴(ban)熱系(xi)統（圖13.3）

  ②. 蒸汽伴熱系統分配站。

   配(pei)(pei)(pei)管設計見圖(tu)13.4。蒸(zheng)(zheng)(zheng)汽(qi)(qi)(qi)分配(pei)(pei)(pei)站(zhan)(zhan)安裝位置(zhi)(zhi)高于(yu)蒸(zheng)(zheng)(zheng)汽(qi)(qi)(qi)總(zong)(zong)管時，分配(pei)(pei)(pei)站(zhan)(zhan)低(di)點可不設排放冷(leng)凝水的(de)蒸(zheng)(zheng)(zheng)汽(qi)(qi)(qi)疏水閥系(xi)統，水平(ping)安裝的(de)分配(pei)(pei)(pei)站(zhan)(zhan)應(ying)(ying)無袋形并坡向蒸(zheng)(zheng)(zheng)汽(qi)(qi)(qi)總(zong)(zong)管。蒸(zheng)(zheng)(zheng)汽(qi)(qi)(qi)分配(pei)(pei)(pei)站(zhan)(zhan)低(di)于(yu)蒸(zheng)(zheng)(zheng)汽(qi)(qi)(qi)總(zong)(zong)管時，其(qi)上游不得有(you)下凹的(de)袋形彎，分配(pei)(pei)(pei)站(zhan)(zhan)的(de)低(di)點應(ying)(ying)設蒸(zheng)(zheng)(zheng)汽(qi)(qi)(qi)疏水閥組(zu)。蒸(zheng)(zheng)(zheng)汽(qi)(qi)(qi)分配(pei)(pei)(pei)站(zhan)(zhan)至少有(you)3根伴管（DN15）送至半徑為3m范圍內的(de)地(di)(di)點時才設置(zhi)(zhi)，否則伴熱(re)供汽(qi)(qi)(qi)管可直接從蒸(zheng)(zheng)(zheng)汽(qi)(qi)(qi)總(zong)(zong)管上引(yin)出。分配(pei)(pei)(pei)站(zhan)(zhan)應(ying)(ying)布(bu)置(zhi)(zhi)在(zai)不妨礙(ai)通行、便(bian)于(yu)操(cao)作的(de)地(di)(di)方(fang)，布(bu)置(zhi)(zhi)應(ying)(ying)考慮整(zheng)齊和美觀(guan)。供汽(qi)(qi)(qi)管的(de)閥門(men)應(ying)(ying)布(bu)置(zhi)(zhi)在(zai)便(bian)于(yu)接近(jin)的(de)地(di)(di)方(fang)。分配(pei)(pei)(pei)站(zhan)(zhan)的(de)蒸(zheng)(zheng)(zheng)汽(qi)(qi)(qi)應(ying)(ying)從蒸(zheng)(zheng)(zheng)汽(qi)(qi)(qi)總(zong)(zong)管的(de)頂(ding)部引(yin)出。

  ③. 蒸汽伴熱系統冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)(shui)回收(shou)(shou)時(shi)，收(shou)(shou)集(ji)站(zhan)(zhan)和冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)(shui)回收(shou)(shou)管的(de)布(bu)(bu)置，見圖13.5。冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)(shui)收(shou)(shou)集(ji)站(zhan)(zhan)高于冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)(shui)總管時(shi)，低點可不設排液(ye)口(kou)；回水(shui)(shui)管應無袋(dai)形并坡向冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)(shui)總管。冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)(shui)收(shou)(shou)集(ji)站(zhan)(zhan)至少(shao)有3根(gen)冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)(shui)支管時(shi)才設置，否則可直接(jie)接(jie)至冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)(shui)總管上。冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)(shui)收(shou)(shou)集(ji)站(zhan)(zhan)應布(bu)(bu)置在不妨礙通行(xing)，便于操作的(de)地方，布(bu)(bu)置應考慮整齊和美觀(guan)。冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)(shui)回水(shui)(shui)管的(de)閥門應布(bu)(bu)置在便于接(jie)近的(de)地方。冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)(shui)回水(shui)(shui)管應從冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)(shui)總管的(de)頂部引入。

  ④. 蒸汽伴熱系統冷凝水(shui)不(bu)回收時(shi)，收集站和冷凝水(shui)回收管的布置，見圖13.6。
