专注通风管道加工·排烟罩

通风管道封闭连接的成功是整个通风管道系统安装成功的关键。如果通风管道的封闭连接不合格，在使用过程中就会发生管道系统的泄漏。因此，在进行通风管道的封闭连接时，我们得要注意以下注意事项。

The success of closed connection of ventilation duct is the key to the successful installation of the whole ventilation duct system. If the closed connection of the ventilation pipe is unqualified, the leakage of the pipe system will occur in the process of use. Therefore, we should pay attention to the following precautions when carrying out the closed connection of the ventilation duct.

1.矩形风管的直管段，无论是由同一块板连接还是由几块板拼接而成，都应具有平整的表面和平直的转角线。组合前，应板材切割面上的切割粉、灰尘和杂物。

1. The straight pipe section of rectangular air duct, whether connected by the same plate or spliced by several plates, should have a flat surface and a straight corner line. Before combination, the cutting powder, dust and sundries on the cutting surface of the plate shall be removed.

2.管段组合后，45度角切边的外接头应贴在铝箔胶带封板的壳面上，每边宽度不小于20mm。用直角尺和钢卷尺检查调整垂直度和对角线偏差，符合规范要求。

2. After the combination of pipe sections, the outer joint with 45 degree angle trimming shall be pasted on the shell surface of the aluminum foil tape sealing plate, and the width of each side shall not be less than 20mm. Check and adjust the perpendicularity and diagonal deviation with a square and steel tape to meet the specification requirements.

3.风管的弧面或折线面下料折叠完成后，应先用平板预组装，然后涂上胶粘剂，以保证管件的几何形状、尺寸和外观。

3. After blanking and folding of the arc surface or broken line surface of the air duct, it should be pre assembled with a flat plate, and then coated with adhesive to ensure the geometry, size and appearance of the pipe fittings.

4.在连接和组合后，管段应垂直放置以在移动前定型。

4. After connection and combination, the pipe section should be placed vertically to shape before moving.

5.铝箔复合保温风管所用的胶粘剂得要是板材制造商认可的专用胶粘剂。如果单独购买胶，得要做连接效果对比试验，经监理和板材厂家检查认可后方可使用。

5. The adhesive used for aluminum foil composite insulation air duct shall be the special adhesive approved by the plate manufacturer. If the brand glue is purchased separately, the connection effect comparison test must be done, and it can only be used after being checked and approved by the supervisor and the plate manufacturer.

6.济南通风管道加工人员认为粘合前需要进行预装配，然后在检查所有接头是否正确配合后涂上粘合胶。粘合时间的控制与季节、温度和粘合剂性能有关。批量加工前应进行样品测试，以确定很好粘合时间。

6. Jinan ventilation pipe processing personnel believe that pre assembly is required before bonding, and then apply adhesive after checking whether all joints fit correctly. The control of bonding time is related to season, temperature and adhesive performance. Sample testing should be carried out before batch processing to determine a good bonding time.

夏热冬冷地区或者夏热冬暖地区的建筑热工设计应当符合现行标准的规定；当采用通风屋面隔热时，通风层长度不宜超过10m，空气层高度宜为20cm左右。

The thermal design of buildings in hot summer and cold winter areas or hot summer and warm winter areas shall comply with the provisions of the current national standards; When ventilation roof insulation is adopted, the length of ventilation layer should not exceed 10m, and the height of air layer should be about 20cm.
