2、M一、概述： 一、概述：General空調(diào)及通風系統(tǒng)中需要采用預隔熱螺旋風管、單層螺旋風管、鍍鋅薄板矩形風管、板材焊接風管（鋼質(zhì)風管）及通風附件等，根據(jù)設計要求，落實風管及附件規(guī)格型號、數(shù)量，采用螺旋風管、鍍鋅方風管或板材焊接風管，嚴格按風管制作工藝和規(guī)范要求執(zhí)行生產(chǎn)安裝。The air conditioner and ventilation system shall adopt the pre-insulated spiral air

3、 duct, single layer spiral air duct, galvanized sheet rectangle air duct, plate welded air duct (steel air duct) and ventilation accessories etc. According to the design requirements to determine the type and quantity of

4、 air duct and accessories, and select the suitable air duct, i.e. spiral air duct, galvanized sheet square air duct or welded air duct. According to the relative constructure technical rules to manufacture and install.三、

5、風管制作 三、風管制作Manufacture the air duct(1) 鍍鋅矩形風管Galvanized rectangle air duct鍍鋅矩形風管連接可采用翻邊、鉚接和焊接，風管與角鋼法蘭連接時，風管壁厚小于 1.5mm，一般采用翻邊鉚接，翻在法蘭的外側(cè)，用角尺靠在風管的縱向折角邊上，使風管中心線與法蘭平面保持垂直，翻邊的尺寸應為 6-9mm。法蘭用料規(guī)格較小的可取上限值，規(guī)格較大的取下限值，防止翻邊卡住螺孔，影響組裝，咬

6、口重疊處，翻邊時應將突出部分鏟平，同時四角不應出現(xiàn)豁口，以免漏風，鉚釘距離不可大于 120mm。Connection of rectangle air duct the flanging, rivet jointing and welding can be adopted, the connect the air duct and angle steel flange, when the thickness of air duct is

7、 less than 1.5mm, generally, flanging and rivet jointing can be adopted, at first the air duct shall be turned over the outside of the flange, and the center of air duct and the surface of flange shall keep vertical meas

8、ured by the set square, dimension of the folded selvedge is 6-9mm. If the dimension of flange is small take the upper limit, if it is big take the lower limit value, do not block the bolt holes to affect the installation
