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(fēng)管道加工密封性差是風(fēng)管裝置工程中較嚴(yán)重的問題，對(duì)工程驗(yàn)收發(fā)生欠好的影響，鍍鋅通風(fēng)管道漏風(fēng)量過大，由于漏風(fēng)將導(dǎo)致通風(fēng)體系工作后有振動(dòng)噪音、能量損失并影響空氣質(zhì)量，如果是用在廢氣處理的當(dāng)?shù)貥O有可能呈現(xiàn)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(fēng)管道密封性差的原因剖析：鉚接方式不妥導(dǎo)致鉚合不行嚴(yán)實(shí)、法蘭密封墊片凸入風(fēng)管內(nèi)；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(fēng)管翻邊四角開裂或四角咬口不緊密；法蘭銜接螺栓松動(dòng)不行嚴(yán)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(fēng)管道加工的密封性差的應(yīng)對(duì)辦法及對(duì)策：風(fēng)管預(yù)制檢查風(fēng)管在法蘭上的翻邊狀況，應(yīng)平坦、緊貼法蘭，寬度不該小于6mm,翻邊四角開裂處應(yīng)用密封膠嵌縫，四角不該呈現(xiàn)豁口，避免漏風(fēng)。裝置檢查密封墊片有無凸入風(fēng)管內(nèi)，銜接的螺栓有無松動(dòng)，管道銜接配件如彎頭、大小頭、天方地圓等咬口有無漏光點(diǎn)，通風(fēng)管道密封性差是工程裝置的首要指標(biāo)，依據(jù)上述原因，提出相關(guān)的應(yīng)對(duì)辦法和對(duì)策，以削減質(zhì)量問題的呈現(xiàn)，保證工程的質(zhì)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(yùn)動(dòng)場(chǎng)館，空氣分配器通常用作空氣出口。 常用的空氣噴射器通風(fēng)管道包括矩形通風(fēng)孔和旋轉(zhuǎn)通風(fēng)孔。 前者適用于風(fēng)速不大且空氣分布要求均勻的零件。 后一種類型的風(fēng)口能夠繞軸線恣意旋轉(zhuǎn)，而且能夠通過風(fēng)口的導(dǎo)向葉片調(diào)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(tǒng)。

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.
