　　1.通風(fēng)和空調(diào)是將室外新鮮空氣和室內(nèi)回風(fēng)先處理為滿意溫度，濕度和新鮮度要求的空氣，然后再處理為不滿意溫度，濕度和濕度要求的空氣的全進程。新鮮度回來運用空間并排放到大氣中。為了完結(jié)空氣的進出運送，只需通過風(fēng)道來完結(jié)。一般來說，這些風(fēng)管大多由鍍鋅板制成。

　　1. Ventilation and air conditioning are the entire process of processing outdoor fresh air and indoor return air into air with satisfactory temperature, humidity, and freshness requirements, and then processing it into air with unsatisfactory temperature, humidity, and humidity requirements. Freshness is utilized to utilize space and released into the atmosphere. To complete the transportation of air in and out, it only needs to be done through air ducts. Generally speaking, these ducts are mostly made of galvanized sheet metal.

　　2.因為鍍鋅板資料，加工機器和東西，運送和設(shè)備的局限性，體系的風(fēng)道由許多部分組成，每個部分一般不逾越2m。為了聯(lián)接它們，有必要在兩個風(fēng)管的接頭處樹立一個接頭。過去，傳統(tǒng)辦法是在每個風(fēng)道的兩頭鉚釘兩個角鋼法蘭。聯(lián)接風(fēng)管時，兩個風(fēng)管的規(guī)范相同。螺栓孔對應(yīng)的法蘭上應(yīng)擰上螺栓，以抵達風(fēng)管聯(lián)接的意圖。依據(jù)當時的規(guī)范和閱歷，每米周邊接頭需求2m以上的角鋼，7套螺栓，9個鉚釘和1m密封墊。

　　2. Due to the limitations of galvanized sheet materials, processing machines and materials, transportation and equipment, the air duct of the system consists of many parts, each of which generally does not exceed 2 meters. In order to connect them, it is necessary to establish a joint at the junction of the two air ducts. In the past, the traditional method was to rivet two angle steel flanges at both ends of each air duct. When connecting air ducts, the specifications for both ducts are the same. The flange corresponding to the bolt hole should be screwed with bolts to achieve the intention of connecting the air duct. According to the regulations and experience at that time, each meter of surrounding joints required more than 2m of angle steel, 7 sets of bolts, 9 rivets, and 1m of sealing gasket.

　　3.為了改變這種狀況，咱們選用通用的板彎法蘭，并運用兩個風(fēng)管接頭相互咬合，并楔入中心件以聯(lián)接風(fēng)管。

　　3. In order to change this situation, we choose a universal bent flange and use two air duct joints to interlock with each other, and wedge the center piece to connect the air ducts.

　　4.依據(jù)現(xiàn)場風(fēng)管的巨細和形狀，將其輸入核算機并由程序軟件進行操控。

　　4. Based on the size and shape of the on-site air ducts, input them into the accounting machine and control them through program software.
