濟(jì)南通風(fēng)管道的合口連接是否成功是整個(gè)通風(fēng)管道系統(tǒng)安裝成功的關(guān)鍵。如果濟(jì)南通風(fēng)管道的于合口連接不合格，管道系統(tǒng)在使用過(guò)程中會(huì)發(fā)生泄漏。因此，在進(jìn)行通風(fēng)管道的連接時(shí)，需要注意以下注意事項(xiàng)。
Whether the joint connection of Jinan ventilation pipe is successful is the key to the successful installation of the whole ventilation pipe system. If the joint connection of Jinan ventilation pipeline is unqualified, the pipeline system will leak in the use process. Therefore, the following precautions should be paid attention to when connecting the ventilation pipes.

1.對(duì)于矩形風(fēng)管的直管段，無(wú)論是用同一塊板連接還是用幾塊板拼接，表面應(yīng)光滑，角線應(yīng)平直。組裝前，應(yīng)清除板材切割面上的切割粉末、灰塵和雜物。
1. For the straight section of rectangular air duct, whether it is connected with the same plate or spliced with several plates, the surface shall be smooth and the corner 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，外部接頭應(yīng)修整45度，板的外表面應(yīng)用鋁箔帶密封。每邊寬度不小于20毫米，用角尺和鋼帶檢查并調(diào)整垂直度和角線，偏差，符合規(guī)范要求。
2. After the pipe section is assembled, the external joint shall be trimmed 45 degrees, and the external surface of the plate shall be sealed with aluminum foil tape. The width of each side shall not be less than 20 mm. Check and adjust the perpendicularity and angle line with angle ruler and steel strip. The deviation shall meet the specification requirements.
3.風(fēng)管的圓弧面或折線面下料彎曲完成后，應(yīng)與平板預(yù)組裝，然后涂上膠粘劑，以保證管件的幾何形狀、尺寸和壓痕。
3. After the arc surface or folded line surface of the air duct is cut and bent, it shall be pre assembled with the flat plate, and then coated with adhesive to ensure the geometry, size and indentation of the pipe fittings.
4.連接和組合后的管段應(yīng)垂直放置，直到它們?cè)谝苿?dòng)前成型。
4. The connected and combined pipe sections shall be placed vertically until they are formed before moving.
5.鋁箔復(fù)合保溫管用膠粘劑應(yīng)為板材制造商認(rèn)可的專用膠粘劑。如果單獨(dú)購(gòu)買粘合劑，需要進(jìn)行連接效果對(duì)比測(cè)試，并且粘合劑要經(jīng)過(guò)監(jiān)理和板制造商的檢查和批準(zhǔn)后才能使用。
5. The adhesive for aluminum foil composite insulation pipe shall be the special adhesive approved by the plate manufacturer. If the brand adhesive is purchased separately, the connection effect comparison test is required, and the adhesive can only be used after being inspected and approved by the supervisor and board manufacturer.
6.粘接前需要進(jìn)行預(yù)組裝，檢查接縫是否全部吻合并正確涂刷膠粘劑，粘接時(shí)間控制及季節(jié)、溫度和粘接性能。在批量處理之前，應(yīng)進(jìn)行樣品測(cè)試，以確定粘合時(shí)間。
6. Pre assembly shall be carried out before bonding. Check whether all joints are closed and applied with adhesive correctly. Control bonding time, season, temperature and bonding performance. Prior to batch processing, sample tests shall be carried out to determine the bonding time.

因此，在濟(jì)南通風(fēng)管道的合口連接完成后，要注意對(duì)通風(fēng)管道接頭連接的詳細(xì)檢查和檢查，以確保通風(fēng)管道的接頭連接是否嚴(yán)密。以上是小編給大家的內(nèi)容分享。我們?cè)谶M(jìn)行通風(fēng)管道合口連接時(shí)，一定要注意以上幾點(diǎn)，希望能對(duì)你有所幫助，如有需要，請(qǐng)及時(shí)聯(lián)系我們。
Therefore, after the joint connection of Jinan ventilation pipe is completed, it is necessary to pay attention to the detailed inspection and inspection of the joint connection of the ventilation pipe to ensure whether the joint connection of the ventilation pipe is tight. The above is the content sharing for you. We must pay attention to the above points when connecting the ventilation pipes. I hope it can help you.
