  ②. 蒸汽伴熱系統(tong)分配站。

   配(pei)管(guan)(guan)設(she)計(ji)見圖13.4。蒸(zheng)(zheng)(zheng)汽分配(pei)站(zhan)(zhan)安(an)裝位置高于蒸(zheng)(zheng)(zheng)汽總(zong)(zong)(zong)(zong)管(guan)(guan)時(shi)(shi)，分配(pei)站(zhan)(zhan)低點(dian)可(ke)不(bu)設(she)排放冷凝水的(de)(de)蒸(zheng)(zheng)(zheng)汽疏(shu)水閥系統，水平安(an)裝的(de)(de)分配(pei)站(zhan)(zhan)應(ying)無袋形(xing)并坡向(xiang)蒸(zheng)(zheng)(zheng)汽總(zong)(zong)(zong)(zong)管(guan)(guan)。蒸(zheng)(zheng)(zheng)汽分配(pei)站(zhan)(zhan)低于蒸(zheng)(zheng)(zheng)汽總(zong)(zong)(zong)(zong)管(guan)(guan)時(shi)(shi)，其(qi)上(shang)游不(bu)得(de)有下(xia)凹(ao)的(de)(de)袋形(xing)彎，分配(pei)站(zhan)(zhan)的(de)(de)低點(dian)應(ying)設(she)蒸(zheng)(zheng)(zheng)汽疏(shu)水閥組。蒸(zheng)(zheng)(zheng)汽分配(pei)站(zhan)(zhan)至少有3根伴管(guan)(guan)（DN15）送至半徑為3m范圍內的(de)(de)地(di)點(dian)時(shi)(shi)才設(she)置，否(fou)則伴熱供(gong)汽管(guan)(guan)可(ke)直接(jie)從蒸(zheng)(zheng)(zheng)汽總(zong)(zong)(zong)(zong)管(guan)(guan)上(shang)引(yin)出(chu)。分配(pei)站(zhan)(zhan)應(ying)布(bu)置在不(bu)妨礙通行、便(bian)于操作的(de)(de)地(di)方，布(bu)置應(ying)考慮整(zheng)齊(qi)和美觀(guan)。供(gong)汽管(guan)(guan)的(de)(de)閥門應(ying)布(bu)置在便(bian)于接(jie)近的(de)(de)地(di)方。分配(pei)站(zhan)(zhan)的(de)(de)蒸(zheng)(zheng)(zheng)汽應(ying)從蒸(zheng)(zheng)(zheng)汽總(zong)(zong)(zong)(zong)管(guan)(guan)的(de)(de)頂部引(yin)出(chu)。

  ③. 蒸汽伴熱系統(tong)冷凝(ning)(ning)(ning)水(shui)回(hui)收(shou)(shou)(shou)時，收(shou)(shou)(shou)集(ji)站(zhan)和(he)(he)冷凝(ning)(ning)(ning)水(shui)回(hui)收(shou)(shou)(shou)管的(de)布(bu)(bu)(bu)置，見(jian)圖(tu)13.5。冷凝(ning)(ning)(ning)水(shui)收(shou)(shou)(shou)集(ji)站(zhan)高(gao)于冷凝(ning)(ning)(ning)水(shui)總(zong)(zong)管時，低點可不設(she)排液(ye)口；回(hui)水(shui)管應(ying)(ying)無袋形并(bing)坡向(xiang)冷凝(ning)(ning)(ning)水(shui)總(zong)(zong)管。冷凝(ning)(ning)(ning)水(shui)收(shou)(shou)(shou)集(ji)站(zhan)至少(shao)有3根冷凝(ning)(ning)(ning)水(shui)支管時才設(she)置，否則(ze)可直接(jie)接(jie)至冷凝(ning)(ning)(ning)水(shui)總(zong)(zong)管上。冷凝(ning)(ning)(ning)水(shui)收(shou)(shou)(shou)集(ji)站(zhan)應(ying)(ying)布(bu)(bu)(bu)置在不妨礙通(tong)行，便(bian)于操(cao)作的(de)地方(fang)，布(bu)(bu)(bu)置應(ying)(ying)考慮整(zheng)齊和(he)(he)美觀。冷凝(ning)(ning)(ning)水(shui)回(hui)水(shui)管的(de)閥(fa)門應(ying)(ying)布(bu)(bu)(bu)置在便(bian)于接(jie)近的(de)地方(fang)。冷凝(ning)(ning)(ning)水(shui)回(hui)水(shui)管應(ying)(ying)從冷凝(ning)(ning)(ning)水(shui)總(zong)(zong)管的(de)頂部引入(ru)。

  ④. 蒸汽伴熱系統(tong)冷凝(ning)水不(bu)回收時，收集站和冷凝(ning)水回收管的(de)布(bu)置，見圖13.6。
