镀锌焊接通风管道加工跟着使用时间的不断增加，鉴于如此，也便是能比较大的延长了风管的使用寿命，里面会堆积很多的杂质，这些杂质长时间存储在管道内，在工作中会加快它的油凝聚，温渡过高，构成气压阀、液压等部件的损坏，对正常工作构成很大的影响。
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.
镀锌通风管道加工密封性差是风管装置工程中较严重的问题，对工程验收发生欠好的影响，镀锌通风管道漏风量过大，由于漏风将导致通风体系工作后有振动噪音、能量损失并影响空气质量，如果是用在废气处理的当地极有可能呈现有毒气体泄漏。
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.
镀锌通风管道密封性差的原因剖析：铆接方式不妥导致铆合不行严实、法兰密封垫片凸入风管内；翻遍量不行，削减密封垫片与翻边接触的面积，影响法兰间的紧密性；风管翻边四角开裂或四角咬口不紧密；法兰衔接螺栓松动不行严紧；
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;
通风管道加工的密封性差的应对办法及对策：风管预制检查风管在法兰上的翻边状况，应平坦、紧贴法兰，宽度不该小于6mm,翻边四角开裂处应用密封胶嵌缝，四角不该呈现豁口，避免漏风。装置检查密封垫片有无凸入风管内，衔接的螺栓有无松动，管道衔接配件如弯头、大小头、天方地圆等咬口有无漏光点，通风管道密封性差是工程装置的首要指标，依据上述原因，提出相关的应对办法和对策，以削减质量问题的呈现，保证工程的质量。
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，例如运动场馆，空气分配器通常用作空气出口。 常用的空气喷射器通风管道包括矩形通风孔和旋转通风孔。 前者适用于风速不大且空气分布要求均匀的零件。 后一种类型的风口能够绕轴线恣意旋转，而且能够通过风口的导向叶片调流出口的方向。 该空气喷射器适用于非固定式本地供气系统。
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.
