style="text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">風管的制作有很多細節，每一個細節的處理都會影響到之后的使用，所以要注意處理方法。</span></p><p style="text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">1.制作風管部分。制作風管截面時，要密切注意是否有漏洞。應以機械密封為主，輔以密封膠處理。每一段<a href='http://www.142779.com/news/473.html' target='_blank' class='key_tag'><font><strong>管道加工</strong></font></a>成型后，都要進行質量檢查。從現場施工來看，角鋼法蘭的強度和密封性能遠高于普通板式法蘭。在變風量系統中，建議優先采用角鋼法蘭。</span></p><p style="text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">2.風管彎頭的生產。風管彎頭位置應按規范要求設置回流片，尤其是尺寸較大的彎頭，會影響氣流，造成局部噪音。設置導葉時，應注意導葉的合理位置和數量。在變風量系統中，風量根據末端需求而變化。由于風管內的流速和流量會發生變化，合理設置彎頭有助于降低局部阻力。</span></p><p style="text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">3.管道法蘭的生產。由于風管采用鋼板法蘭連接，大型三通和彎頭的制作需要拼接板。但是你要知道法蘭的位置是不允許拼接的。如果其強度不符合我方要求，則應采用角鋼法蘭或根據設計和規范要求進行處理。在變風量系統中，由于管道內的靜壓穩定，對風管的強度和密封性能都有要求。</span></p><p style="text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">4.風管三通的制作：在VAV變風量系統中，由于三通兩側的風量在不同工況下會發生變化，隔板或回流片會嚴重限制風量分配，因此，三通位置可以不安裝擋板或中間加強隔板。但是，構件的強度得要滿足設計和規范要求。請采用角鋼法蘭或根據設計和規范要求進行加固。</span></p><p
