　　通風(fēng)管道在我們現(xiàn)在的城市建設(shè)中非常重要，特別是安裝質(zhì)量問題，直接影響了空氣的交換，影響了人們的正常工作活動(dòng)，效率，那么它的安裝質(zhì)量受到哪些因素的影響呢?

　　Ventilation duct is very important in our urban construction, especially the installation quality problem, which directly affects the air exchange, affects people's normal work activities and efficiency, so what factors affect its installation quality?

　　1、施工前的準(zhǔn)備工作

　　1. Preparation before construction

　　俗話說，“磨刀不誤砍柴”，充分的說明準(zhǔn)備是保證風(fēng)管安裝質(zhì)量的前提。準(zhǔn)備清潔管道的制作，無論采用工廠集中制作還是現(xiàn)場制作方式，都要保證場所的清潔和關(guān)閉，具有符合條件的采光和照明條件。另外，還要對(duì)制作好的方管進(jìn)行看管，盡量避免污染。

　　As the saying goes, "sharpening the knife does not cut firewood by mistake". Sufficient preparation is the premise to ensure the installation quality of air duct. Preparation for the production of clean pipes, whether factory centralized production or on-site production, should ensure that the site is clean and closed, with qualified lighting and lighting conditions. In addition, it is necessary to take care of the square tube to avoid pollution.

　　2、風(fēng)管材質(zhì)的選擇

　　2. Selection of duct material

　　通風(fēng)管道材質(zhì)的選擇對(duì)管道的施工質(zhì)量也有很大影響。一般來說，為了保證管道的重量，需要較小板厚的管道，但需要綜合考慮管道的尺寸和壓力水平。從設(shè)計(jì)角度來看，值得注意的是，一個(gè)系統(tǒng)可以同時(shí)具有對(duì)應(yīng)于不同靜態(tài)壓力水平的幾個(gè)管道厚度。

　　The selection of ventilation pipe material also has a great impact on the construction quality of the pipeline. Generally speaking, in order to ensure the weight of the pipe, the pipe with smaller plate thickness is needed, but the pipe size and pressure level should be considered comprehensively. From a design point of view, it is worth noting that a system can have several pipe thicknesses corresponding to different static pressure levels at the same time.

　　3、風(fēng)管的橫向連接

　　3. Transverse connection of air duct

　　風(fēng)管的橫向連接有一定的應(yīng)力。這種連接方法可以說是延長空氣導(dǎo)管長度的手段，并且還具有增強(qiáng)剛性和保持空氣導(dǎo)管橫向尺寸的功能通常，橫向連接方式是角鋼法蘭連接。這種連接模式取決于壁厚，也取決于連接類型和板墻加固模式。

　　The transverse connection of air duct has certain stress. This connection method can be said to be a means to extend the length of the air duct, and also has the function of enhancing the rigidity and maintaining the transverse dimension of the air duct. Generally, the transverse connection mode is angle steel flange connection. The connection mode depends on the wall thickness, the connection type and the reinforcement mode of the panel wall.

　　4、風(fēng)管的縱向縫接合

　　4. Longitudinal joint of air duct

　　風(fēng)管的縱接縫接合方式可根據(jù)情況選擇對(duì)應(yīng)的方式。在中、低壓風(fēng)管中常常使用扣式咬口連接，對(duì)于矩形風(fēng)管，聯(lián)合咬口使用無任何壓力級(jí)別，因此使用扣式咬口可以節(jié)省一道翻邊工序，目前大多數(shù)的風(fēng)管縱向縫接合都采用了扣式咬口。對(duì)于立縫和封蓋式立縫可以使用鉚釘、自攻螺絲、點(diǎn)焊、壓凸凹痕等方法緊固。

　　The joint mode of longitudinal joint of air duct can be selected according to the situation. In the medium and low pressure air duct, the button type bite connection is often used. For rectangular air duct, the joint bite has no pressure level, so the use of button type bite can save a flanging process. At present, most of the longitudinal seam joints of air duct adopt the button type bite. Rivets, self tapping screws, spot welding and dent pressing can be used to fasten the vertical seam and cover type vertical seam.

　　5、風(fēng)管的存放

　　5. Storage of air duct

　　預(yù)制好的風(fēng)管，需要做好存放工作，以免受到二次污染。可將管口用塑料布等密封材料封住，然后將風(fēng)管分門別類堆放好。使用管道前，請(qǐng)注意清洗作業(yè)，確認(rèn)板材表面沒有腐蝕，干燥后不進(jìn)行清掃。

　　The prefabricated air duct needs to be stored well to avoid secondary pollution. The pipe orifice can be sealed with plastic cloth and other sealing materials, and then the air duct can be stacked in different categories. Before using the pipeline, please pay attention to the cleaning operation, make sure that the surface of the plate is not corroded, and do not clean after drying.
