        通風管道合口連接時有哪些注意事項?

        來源:http://www.boursomarket.com 日期:2021-06-10 發布人:jntfgd

        通風管道的合口連接是否成功是整個通風管道系統安裝成功與否的關鍵,通風管道的合口連接如果不合格,就會在使管道系統在使用過程中發生泄露的現象,因此,在進行通風管道的合口連接時,我們一定要注意以下提到的注意事項。
        Whether the joint connection of ventilation pipe is successful or not is the key to the successful installation of the whole ventilation pipe system. If the joint connection of ventilation pipe is not qualified, it will cause the leakage of the pipe system in the process of use. Therefore, when the joint connection of ventilation pipe is carried out, we must pay attention to the following precautions.
        1、矩形風管直管段,不管是同一板材連接,還是幾塊板材組合拼接,表面需平整、角線順直。組合前應清除板材切口表面的切割粉末、灰塵及雜物。
        1. Whether the straight section of rectangular duct is connected by the same plate or assembled by several plates, the surface shall be smooth and the corner line shall be straight. Before combination, the cutting powder, dust and sundries on the cutting surface of the plate shall be removed.
        2、管段組合后45度角切邊外部接縫,需貼鋁箔膠帶封合板材外殼面,每邊寬度不少于20mm.用角尺、鋼卷尺檢查調整垂直度及對角線偏差,并符合規范要求。
        2. After the pipe section is assembled, the outer joint of 45 degree angle trimming shall be sealed with aluminum foil tape, and the width of each side shall not be less than 20 mm. The perpendicularity and diagonal deviation shall be checked and adjusted with angle ruler and steel tape, and shall meet the specification requirements.
        3、風管的圓弧面或折線面完成下料并折壓成型后,應與平面板預組合無誤后在涂刷粘合劑,以保證管件的幾何形狀尺寸及觀感。
        3. After the arc surface or broken line surface of the air duct is cut and folded, it should be pre assembled with the plane plate and then coated with adhesive to ensure the geometric size and appearance of the pipe.
        4、連接組合后的管段應垂直擺放至定型后方可移動。
        4. After connecting and assembling, the pipe section shall be placed vertically until it is shaped before moving.
        5、鋁箔復合保溫風管所用粘合劑須按板材廠商認定的專用粘合劑,如另行采購品牌粘合劑,必須做連接效果對比試驗,并經監理、板材商檢查、認可后方可使用。
        5. The adhesive used for the aluminum foil composite insulation duct shall be the special adhesive recognized by the sheet manufacturer. If the brand adhesive is purchased separately, the connection effect comparison test must be conducted, and it can only be used after being inspected and approved by the supervisor and the sheet manufacturer.
        6、粘結前須預組合,檢查接縫全部貼合無誤再涂刷粘合劑,粘合時間控制與季節、溫度及粘合劑性能有關。批量加工前應作樣板試驗,確定粘合時間。
        6. Before bonding, it is necessary to pre assemble, check that all joints fit correctly, and then brush the adhesive. The bonding time control is related to season, temperature and adhesive performance. Sample test should be done before batch processing to determine the bonding time.
