专注通风管道加工·排烟罩

通风管道的合口连接是否成功是整个通风管道系统安装成功与否的关键，通风管道的合口连接如果不合格，就会在使管道系统在使用过程中发生泄露的现象。所以说通风管道合口连接时要知道正确的操作，下面济南通风管道加工人员为您解答。

The success of the joint connection of the ventilation pipe is the key to the success of the installation of the entire ventilation pipe system. If the joint connection of the ventilation pipe is not qualified, the leakage will occur in the use of the pipe system. Therefore, you should know the correct operation when connecting the ventilation pipes. Now, the ventilation pipe processing personnel in Jinan will answer for you.

1、矩形风管直管段，不管是同一板材连接，还是几块板材组合拼接，表面需平整、角线顺直。组合前应板材切口表面的切割粉末、灰尘及杂物。

1. The straight section of rectangular air duct, whether connected with the same plate or combined with several plates, shall have a flat surface and straight corner lines. Before assembly, the cutting powder, dust and sundries on the cut surface of the plate shall be removed.

2、管段组合后45度角切边外部接缝，需贴铝箔胶带封合板材外壳面，每边宽度不少于20mm.用角尺、钢卷尺检查调整垂直度及对角线偏差，并符合规范要求。

2. After the pipe section is assembled, the outer joint of the 45 ° angle cut edge shall be sealed with aluminum foil tape on the surface of the plate shell. The width of each side shall not be less than 20mm. The perpendicularity and diagonal deviation shall be checked and adjusted with an angle ruler and a steel tape, and shall meet the specification requirements.

3、风管的圆弧面或折线面完成下料并折压成型后，应与平面板预组合无误后在涂刷粘合剂，以保证管件的几何形状尺寸及观感。

3. After the arc surface or fold line surface of the air duct is cut and folded, it shall be pre assembled with the plane plate and then coated with adhesive to ensure the geometric shape, size and appearance of the pipe fittings.

4、连接组合后的管段应垂直摆放定型后方可移动。

4. The pipe section after connection and combination shall be placed vertically until it is finalized before moving.

5、铝箔复合保温风管所用粘合剂须按板材厂商认定的专用粘合剂，如另行采购粘合剂，须做连接效果对比试验，并经监理、板材商检查、认可后方可使用。

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

6、粘结前须预组合，检查接缝全部贴合无误再涂刷粘合剂，粘合时间控制与季节、温度及粘合剂性能有关。批量加工前应作样板试验，确定合适的粘合时间。

6. Before bonding, pre assembly shall be carried out, and the adhesive shall be applied after all joints are checked for correct adhesion. The bonding time control is related to season, temperature and adhesive performance. Sample test shall be conducted before batch processing to determine proper bonding time.
