  ②. 蒸汽伴熱系統分配站。

   配管設(she)計見(jian)圖13.4。蒸汽(qi)(qi)(qi)(qi)(qi)分(fen)(fen)(fen)(fen)配站(zhan)(zhan)(zhan)安裝(zhuang)(zhuang)位置高于(yu)蒸汽(qi)(qi)(qi)(qi)(qi)總(zong)管時(shi)，分(fen)(fen)(fen)(fen)配站(zhan)(zhan)(zhan)低(di)點(dian)可不(bu)設(she)排(pai)放(fang)冷凝(ning)水的(de)蒸汽(qi)(qi)(qi)(qi)(qi)疏水閥系統，水平安裝(zhuang)(zhuang)的(de)分(fen)(fen)(fen)(fen)配站(zhan)(zhan)(zhan)應(ying)(ying)(ying)無袋形(xing)并坡向蒸汽(qi)(qi)(qi)(qi)(qi)總(zong)管。蒸汽(qi)(qi)(qi)(qi)(qi)分(fen)(fen)(fen)(fen)配站(zhan)(zhan)(zhan)低(di)于(yu)蒸汽(qi)(qi)(qi)(qi)(qi)總(zong)管時(shi)，其上游(you)不(bu)得有下凹的(de)袋形(xing)彎，分(fen)(fen)(fen)(fen)配站(zhan)(zhan)(zhan)的(de)低(di)點(dian)應(ying)(ying)(ying)設(she)蒸汽(qi)(qi)(qi)(qi)(qi)疏水閥組(zu)。蒸汽(qi)(qi)(qi)(qi)(qi)分(fen)(fen)(fen)(fen)配站(zhan)(zhan)(zhan)至少有3根伴(ban)管（DN15）送至半徑為3m范圍內的(de)地點(dian)時(shi)才設(she)置，否則伴(ban)熱供(gong)汽(qi)(qi)(qi)(qi)(qi)管可直接從(cong)蒸汽(qi)(qi)(qi)(qi)(qi)總(zong)管上引出(chu)。分(fen)(fen)(fen)(fen)配站(zhan)(zhan)(zhan)應(ying)(ying)(ying)布(bu)置在不(bu)妨礙通行、便于(yu)操作的(de)地方，布(bu)置應(ying)(ying)(ying)考慮(lv)整齊和美觀。供(gong)汽(qi)(qi)(qi)(qi)(qi)管的(de)閥門應(ying)(ying)(ying)布(bu)置在便于(yu)接近的(de)地方。分(fen)(fen)(fen)(fen)配站(zhan)(zhan)(zhan)的(de)蒸汽(qi)(qi)(qi)(qi)(qi)應(ying)(ying)(ying)從(cong)蒸汽(qi)(qi)(qi)(qi)(qi)總(zong)管的(de)頂(ding)部引出(chu)。

  ③. 蒸汽伴(ban)熱系統(tong)冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)回(hui)收(shou)(shou)時(shi)，收(shou)(shou)集站(zhan)和冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)回(hui)收(shou)(shou)管(guan)(guan)的(de)(de)布置(zhi)(zhi)(zhi)，見圖(tu)13.5。冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)收(shou)(shou)集站(zhan)高于冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)總管(guan)(guan)時(shi)，低(di)點(dian)可(ke)不(bu)設排液口；回(hui)水(shui)管(guan)(guan)應無(wu)袋(dai)形并坡向冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)總管(guan)(guan)。冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)收(shou)(shou)集站(zhan)至少有3根冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)支(zhi)管(guan)(guan)時(shi)才(cai)設置(zhi)(zhi)(zhi)，否則可(ke)直接接至冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)總管(guan)(guan)上。冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)收(shou)(shou)集站(zhan)應布置(zhi)(zhi)(zhi)在(zai)不(bu)妨礙通行(xing)，便(bian)于操(cao)作的(de)(de)地(di)方，布置(zhi)(zhi)(zhi)應考慮整齊(qi)和美觀。冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)回(hui)水(shui)管(guan)(guan)的(de)(de)閥門應布置(zhi)(zhi)(zhi)在(zai)便(bian)于接近的(de)(de)地(di)方。冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)回(hui)水(shui)管(guan)(guan)應從冷(leng)(leng)凝(ning)(ning)(ning)(ning)水(shui)總管(guan)(guan)的(de)(de)頂部引入(ru)。

  ④. 蒸汽伴熱系統冷(leng)凝水不回收(shou)時，收(shou)集站和冷(leng)凝水回收(shou)管的布置，見圖13.6。
