③法兰垫料不能挤入或凸入管内,否则会增大流动阻力,增加管内积尘。 ④法兰连接后,严禁往法兰缝隙填塞垫料。 ⑤连接法兰的螺母应在同一侧。 ⑥玻璃钢法兰连接采用镀锌螺栓,两侧应加镀锌垫圈。
12、 风管无法兰连接 ①抱箍式连接:主要用于钢板圆风管和螺旋风管连接,先把每一管段的两端轧出鼓筋,并使其
一端缩为小口。安装时按气流方向把小口插入大口,外面用宽度≥100mm 的与风管同材料的 钢制抱箍将两个端的鼓箍抱紧连接,最后用螺栓穿在耳环中间固定拧紧。 ②插条式连接:用于 b≤630mm 的矩形风管连接。将 C 形插条插入风管两端,然后压实。其形 状和接管方法见图。 ③ 软管式连接:主要用于风管与部件(如散热器、静压箱侧送风口等)的相连。安装时,软管 两端套在连接的管外,然后用特别软卡把软管箍紧。







13、 风管安装就位可根据现场情况,在地面连成一片的长度,用吊装的方法就位,也可以把风



管一节一节地放在支架上,逐节连接。一般顺序是先干管,后支管。立管的安装一般是由

下向*沧啊0沧熬臀缓蠼姓*,找正,达到设计规定的要求。

14、 风管的连接应*直、不扭曲。明装风管水*安装,水*度的允许偏差为 3/1000,总偏差不

应大于 20mm。明装风管垂直安装,垂直度的允许偏差为 2/1000,总偏差不应大于 20mm。

暗装风管的位置,应正确、无明显偏差。

15、 风管安装应注意的问题:

①风管采用无法兰连时,接口处应严密、牢固。矩形风管四角必须有定位及密封措施。风管连接

两*面应*直,不得错位及扭曲。

②安装在支架上的圆形风管应设托座。

③风管穿出屋面外应设置防雨罩。

④输送易产生冷凝水的风管,应按设计要求的坡度安装。风管底部不能有纵向接缝,如有接缝应

用密封处理。

⑤钢板风管与砖、混凝土风道的插接应顺应气流方向风管与风道结合面必须进行密封处理。

⑥保温风管的支、吊架宜设在保温层外部,并不得损坏保温层。

⑦送风管和与总管采用垂直插接时,接口处应设置导风调节装置。

16、 风管部件安装必须符合下列规定:

1)风管部件及操作机构的安装,应能保证其正常的使用功能,并便于操作;

2)斜插板风阀的安装,阀板必须为向上拉启;水*安装时,阀板还应为顺气流方向插入;
