通風(fēng)管道在城市建筑中十分的重要，尤其是它的裝置質(zhì)量更是影響到空氣的交換，影響人們的正常的“活動(dòng)”，影響人們的工作效率。
Ventilation duct is very important in urban architecture, especially the quality of its installation affects the air exchange, affects people's normal "activities" and affects people's work efficiency.
1、做好施工前的準(zhǔn)備工作
1. Make preparations before construction
俗話(huà)說(shuō)“磨刀不誤砍柴工”，充分的準(zhǔn)備工作是確保風(fēng)管裝置質(zhì)量的前提。在準(zhǔn)備凈化風(fēng)管的制造時(shí)，無(wú)論是采納工廠(chǎng)集中制造還是現(xiàn)場(chǎng)制造辦法，都有必要確保場(chǎng)地的潔凈和封閉，并具有契合條件的采光和照明條件。除此外，還要對(duì)制造好的方管進(jìn)行看管，盡量防止污染。
As the saying goes, "sharpening a knife does not mistake a woodcutter". Sufficient preparation is the premise to ensure the quality of the air duct device. When preparing for the manufacturing of purification air duct, it is necessary to ensure that the site is clean and closed, and has suitable lighting and lighting conditions, no matter whether centralized manufacturing in the factory or on-site manufacturing method is adopted. In addition, it is necessary to take care of the manufactured square tube to prevent pollution as much as possible.
2、排煙管道風(fēng)管原料的挑選
2. Selection of raw materials for exhaust duct
風(fēng)管原料的挑選，對(duì)風(fēng)管的施工質(zhì)量也有很大的影響。一般來(lái)說(shuō)為了確保風(fēng)管的重量，需采用zui小板厚的風(fēng)管，但除此外還需要?dú)w納考慮風(fēng)管的尺度和壓力級(jí)別。從設(shè)計(jì)角度來(lái)看，值得注意的是一個(gè)系統(tǒng)能夠一起存在幾種對(duì)應(yīng)于不同靜壓級(jí)別的風(fēng)管板厚。
The selection of air duct materials also has a great impact on the construction quality of air duct. Generally speaking, in order to ensure the weight of the air duct, it is necessary to use Zui small plate thick air duct, but in addition to summing up and considering the size and pressure level of the air duct. From a design point of view, it is worth noting that a system can have several duct plate thicknesses corresponding to different static pressure levels together.
3、風(fēng)管的橫向銜接
3. Horizontal connection of air duct
風(fēng)管的橫向銜接有必定考究，這種銜接辦法能夠說(shuō)是是延續(xù)風(fēng)管長(zhǎng)度的一種手段，還具有增強(qiáng)剛度及堅(jiān)持風(fēng)管jing確地橫向尺度的作用。一般橫向銜接的辦法是角鋼法蘭銜接，這種銜接辦法取決于壁厚，更取決于銜接種類(lèi)及板壁加固辦法。
The horizontal connection of the air duct must be studied. This connection method can be said to be a means to continue the length of the air duct. It also has the function of strengthening the rigidity and insisting on the correct horizontal dimension of the air duct. Generally, the method of horizontal connection is angle steel flange connection, which depends on the wall thickness, more on the type of connection and the method of plate wall reinforcement.
4、風(fēng)管的縱向縫接合
4. Longitudinal seam joint of air duct
風(fēng)管的縱向縫接合辦法能夠根據(jù)實(shí)際情況，挑選對(duì)應(yīng)的辦法。在中、低壓風(fēng)管中常常運(yùn)用扣式咬口銜接，關(guān)于矩形風(fēng)管，聯(lián)合咬口運(yùn)用無(wú)任何壓力級(jí)別，因而運(yùn)用扣式咬口能夠節(jié)約一道翻邊工序，現(xiàn)在大多數(shù)的風(fēng)管縱向縫接合都采用了扣式咬口。關(guān)于立縫和封蓋式立縫能夠運(yùn)用鉚釘、自攻螺絲、點(diǎn)焊、壓凸凹痕等辦法緊固。
The longitudinal joint method of air duct can select the corresponding method according to the actual situation. In the middle and low pressure air ducts, the buckle type bite is often used for connection. As for the rectangular air ducts, the joint bite is used without any pressure level, so the use of buckle type bite can save a flanging process. Now, most of the longitudinal seam joints of air ducts adopt buckle type bite. For vertical seam and cover type vertical seam, rivets, self tapping screws, spot welding, embossing dent and other methods can be used for fastening.
廚房排煙的長(zhǎng)處就是可以運(yùn)用廚房排煙的煙道設(shè)置合理，幫忙我們?cè)谥箫垥r(shí)分有煙霧出現(xiàn)，可以跟著煙道管走掉，從而對(duì)我們的身體不會(huì)構(gòu)成太大的傷害，并且這個(gè)廚房煙道在平房規(guī)劃中還能起到有助燒火炒菜旺的長(zhǎng)處。
The advantage of kitchen smoke exhaust is that the flue of kitchen smoke exhaust can be set reasonably, which can help us to have smoke when cooking, and can follow the flue pipe to go away, so as to not cause too much harm to our body, and the kitchen flue can also play a strong role in the bungalow planning to help fire and stir up vegetables.
煙道管有兩個(gè)設(shè)置，我們不能少一個(gè)過(guò)程，主煙道貫穿整個(gè)樓體，而副煙道是相對(duì)獨(dú)立的。一般家里的油煙會(huì)先到副煙道里，然后再通過(guò)隔板上的孔進(jìn)入主煙道，這樣可保證每戶(hù)的油煙是隔離開(kāi)來(lái)的。而假設(shè)將副煙道直接連接主煙道，就會(huì)由于壓力過(guò)低而導(dǎo)致倒煙或串煙現(xiàn)象。
There are two sets of flue pipes. We can't do without one process. The main flue runs through the whole building, while the auxiliary flue is relatively independent. In general, the lampblack in the house will first enter the auxiliary flue, and then enter the main flue through the hole on the partition board, so as to ensure that the lampblack in each house is isolated. If the secondary flue is directly connected to the main flue, it will cause the phenomenon of inverted smoke or cross smoke due to the low pressure.
