The consideration of ventilation ducts mainly includes air vents, ducts, dampers, wind equipment, and some accessories. The galvanized circular flange mainly emphasizes the operation precautions of ventilation ducts and dampers in the ventilation duct system this time: it is the identification of air ducts before the pipeline renovation, and one of the contents is clear, that is, the elevation of the pipeline. When using the height adjustment command to view, sometimes the displayed results are different. This is because the elevation of the pipeline and pipeline is the center elevation of the pipeline or pipeline. Whenever the pipeline height is high, it is considered a pipeline.

通风管道是连接风机、空气处理设备和进风口的管道，是通风设备的重要组成部分。设计通风管道时，应注意通风管道中的阻力，设应尽可能减小阻力。.设计通风管道时，弯头应尽可能少，两个弯头之间的距离应较大。当两弯头之间的距离为管径的3倍时，阻力增加约80%。如果是5倍，只会增加30%。自通风管道问世以来，由于其自身的特点和低价席卷了整个市场，受到许多制造商的欢迎。在使用中，要学会该学会维护和清洁通风管道，以便更好地发挥自己的作用。实用：这点应该是重要的一点,也是客户们所追求的一点,只有达到了工程的效果,这样客户才能认可我们的产品。

Ventilation ducts are important components of ventilation equipment that connect fans, air handling equipment, and air intakes. When designing ventilation ducts, attention should be paid to the resistance in the ducts, and the design should minimize the resistance as much as possible When designing ventilation ducts, the number of elbows should be minimized and the distance between the two elbows should be relatively large. When the distance between the two elbows is three times the pipe diameter, the resistance increases by about 80%. If it is 5 times, it will only increase by 30%. Since the introduction of ventilation ducts, they have swept the entire market due to their own characteristics and low prices, and have been welcomed by many manufacturers. In use, it is important to learn how to maintain and clean ventilation ducts in order to better play their role. Practical: This should be an important point and also a pursuit of customers. Only by achieving the engineering effect can customers recognize our products.
