　　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，無論是與同一板連接還是與多個板組合，其表面應平整，角度線應平直。拼裝前應將板材切割面上的切割粉、灰塵、雜物等清除。

　　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. 管段組合后，將邊的外縫剪成45度角，用鋁箔膠帶封好板材的殼面，每邊寬度不小于20mm。用直尺和鋼卷尺檢查調整垂直度和對角偏差，滿足規范要求。

　　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.管道的弧形或折線面沖裁折壓成形后，與平面板預組合后涂膠，以保證管件的幾何形狀、尺寸和外觀。

　　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. 連接組合后，將管段豎直放置，直到設置好后再移動。

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

　　5. 鋁箔復合保溫管道用膠粘劑應是板材廠家認可的專用膠粘劑。如果是單獨購買的品牌膠，連接效果必須與試驗進行比較，并且必須經過板材生產廠家的監督檢查和批準后方可使用。

　　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、粘接前必須預組合，檢查各接縫是否都合適，然后施膠，粘接時間控制及季節、溫度及粘接性能。樣品測試應在批量加工前進行，以確定的粘合時間。

　　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.

　　，通風管道的密封連接完成后，需要注意對通風管道的密封連接進行詳細檢查，確保通風管道的密封連接嚴密。以上是為大家分享的內容，我們在通風管道接頭的連接上，一定要注意以上幾點，希望對您有所幫助。

　　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.
