The key to the success of closing the ventilation pipe connection is the successful installation of the ventilation pipe system. If the ventilation pipe connection is not qualified, the leakage of the pipe system occurs in the use process. Therefore, when closing the ventilation pipe connection, we must pay attention to the following matters.

　　1. 矩形直管截面，无论是与同一板连接还是与多个板组合，其表面应平整，角度线应平直。拼装前应将板材切割面上的切割粉、灰尘、杂物等清除。

　　1. For the section of rectangular straight pipe, whether it is connected with the same plate or combined with multiple plates, its surface shall be flat and the angle line shall be straight. Before assembly, the cutting powder, dust and sundries on the cutting surface of the plate shall be removed.

　　2. 管段组合后，将边的外缝剪成45度角，用铝箔胶带封好板材的壳面，每边宽度不小于20mm。用直尺和钢卷尺检查调整垂直度和对角偏差，满足规范要求。

　　2. After the pipe section is assembled, the outer seam of the edge shall be cut into a 45 degree angle, and the shell surface of the plate shall be sealed with aluminum tape, and the width of each side shall not be less than 20 mm. Check and adjust perpendicularity and diagonal deviation with ruler and steel tape to meet the specification requirements.

　　3.管道的弧形或折线面冲裁折压成形后，与平面板预组合后涂胶，以保证管件的几何形状、尺寸和外观。

　　3. After the arc-shaped or broken line surface of the pipe is cut and pressed, it is pre assembled with the plane plate and then coated with glue to ensure the geometry, size and appearance of the pipe fittings.

　　4. 连接组合后，将管段竖直放置，直到设置好后再移动。

　　4. After connecting the assembly, place the pipe segment vertically until it is set before moving.

　　5. 铝箔复合保温管道用胶粘剂应是板材厂家认可的专用胶粘剂。如果是单独购买的胶，连接效果必须与试验进行比较，并且必须经过板材生产厂家的监督检查和批准后方可使用。

　　5. The adhesive for aluminum foil composite insulation pipeline shall be the special adhesive approved by the plate manufacturer. If the brand adhesive is purchased separately, the connection effect must be compared with the test, and it can only be used after the supervision, inspection and approval of the plate manufacturer.

　　6、粘接前必须预组合，检查各接缝是否都合适，然后施胶，粘接时间控制及季节、温度及粘接性能。样品测试应在批量加工前进行，以确定的粘合时间。

　　6、 Before bonding, it is necessary to pre assemble, check whether all joints are suitable, then apply glue, control bonding time, season, temperature and bonding performance. Sample testing shall be carried out prior to batch processing to determine the best bonding time.

　　，通风管道的密封连接完成后，需要注意对通风管道的密封连接进行详细检查，确保通风管道的密封连接严密。以上是为大家分享的内容，我们在通风管道接头的连接上，一定要注意以上几点，希望对您有所帮助。

　　Finally, after the sealing connection of the ventilation pipe is completed, it is necessary to check the sealing connection of the ventilation pipe in detail to ensure that the sealing connection of the ventilation pipe is tight. The above is for you to share. We must pay attention to the above points in the connection of ventilation pipe joints, hoping to help you.
