With the continuous increase of service time, the processing of galvanized and welded ventilation pipes can greatly extend the service life of the air pipes. There will be a lot of impurities in the air pipes. These impurities will be stored in the pipes for a long time, which will accelerate the oil condensation during the work. The temperature is too high, which will cause damage to the air valves, hydraulic and other components, and have a great impact on the normal work.

鍍鋅通風管道加工密封性差是風管裝置工程中較嚴重的問題，對工程驗收發生欠好的影響，鍍鋅通風管道漏風量過大，由于漏風將導致通風體系工作后有振動噪音、能量損失并影響空氣質量，如果是用在廢氣處理的當地極有可能呈現有毒氣體泄漏。

The poor processing and sealing performance of galvanized ventilation ducts is a serious problem in the air duct installation project, which has a bad impact on the project acceptance. The amount of air leakage of galvanized ventilation ducts is too large, which will cause vibration noise, energy loss and affect the air quality after the ventilation system works. If it is used for waste gas treatment, it is very likely to present toxic gas leakage.

鍍鋅通風管道密封性差的原因剖析：鉚接方式不妥導致鉚合不行嚴實、法蘭密封墊片凸入風管內；翻遍量不行，削減密封墊片與翻邊接觸的面積，影響法蘭間的緊密性；風管翻邊四角開裂或四角咬口不緊密；法蘭銜接螺栓松動不行嚴緊；

Analysis of the reasons for poor sealing of galvanized ventilation ducts: improper riveting method leads to poor riveting, and flange sealing gasket protrudes into the air duct; The amount of turning over is not enough, and the contact area between the sealing gasket and the flange is reduced, which affects the tightness between flanges; The four corners of the air duct flange are cracked or the four corners are not closely seamed; Flange connecting bolts are loose and not tight;

通風管道加工的密封性差的應對辦法及對策：風管預制檢查風管在法蘭上的翻邊狀況，應平坦、緊貼法蘭，寬度不該小于6mm,翻邊四角開裂處應用密封膠嵌縫，四角不該呈現豁口，避免漏風。裝置檢查密封墊片有無凸入風管內，銜接的螺栓有無松動，管道銜接配件如彎頭、大小頭、天方地圓等咬口有無漏光點，通風管道密封性差是工程裝置的首要指標，依據上述原因，提出相關的應對辦法和對策，以削減質量問題的呈現，保證工程的質量。

Measures and countermeasures for poor sealing of air duct processing: the flanging of air duct on the flange shall be checked for air duct prefabrication, which shall be flat and close to the flange, and the width shall not be less than 6mm. The cracks at the four corners of the flanging shall be caulked with sealant, and the four corners shall not show gaps to avoid air leakage. The device mainly checks whether the sealing gasket protrudes into the air duct, whether the connecting bolts are loose, whether the pipe connecting fittings such as elbows, reducers, square and round joints have light leaks, and poor sealing of the ventilation pipe is the primary indicator of the engineering device. Based on the above reasons, relevant countermeasures are proposed to reduce the appearance of quality problems and ensure the quality of the project.

在大型建筑物中，例如運動場館，空氣分配器通常用作空氣出口。 常用的空氣噴射器通風管道包括矩形通風孔和旋轉通風孔。 前者適用于風速不大且空氣分布要求均勻的零件。 后一種類型的風口能夠繞軸線恣意旋轉，而且能夠通過風口的導向葉片調流出口的方向。 該空氣噴射器適用于非固定式本地供氣系統。

In large buildings, such as sports venues, air distributors are usually used as air outlets. Commonly used air ejector ventilation ducts include rectangular vents and rotary vents. The former is applicable to parts with small wind speed and uniform air distribution requirements. The latter type of tuyere can freely rotate around the axis, and can adjust the direction of the air flow outlet through the guide vane of the tuyere. The air injector is applicable to non fixed local air supply system.
