The ventilation pipe plays an important role in life, and it plays an important role in helping air circulation. Linyi ventilation pipe manufacturer tells us how to reduce the resistance of ventilation pipe

1、通风91在线视频观看设弯曲的角度要尽量呈弧形。

1. When designing the ventilation pipe, the bending angle should be as arc as possible.

2、通风91在线视频观看设弯头要尽量少，两个弯头的距离要大些。当两个弯头的距离为管径的3倍时，阻力大约增加80%;若为5倍时，则仅增加30%。

2. In the design of ventilation duct, the elbows should be as few as possible, and the distance between the two elbows should be larger. When the distance between the two elbows is three times of the pipe diameter, the resistance increases about 80%; If it is 5 times, it will only increase by 30%.

3、尽量直立或倾斜放置，设置清扫口，连接部分应严密不漏气，并便于检修。

3. It shall be placed vertically or obliquely as far as possible, and the cleaning opening shall be set. The connection part shall be tight without air leakage and easy for maintenance.

4、所用材料应具有导热性小、保温，耐腐蚀、耐火等性能。

4. The materials used should have low thermal conductivity, thermal insulation, corrosion resistance, fire resistance and other properties.

5、通风91在线视频观看设不宜太长，在可能条件下；管径要粗，式样以圆形为佳。

5. The ventilation duct should not be too long when it is designed, if possible; The pipe diameter should be thick, and the round shape is better.

6、支管的半径不得小于主管半径的1/2-1/3，便于通风91在线视频观看加工。

6. The radius of the branch pipe shall not be less than 1 / 2-1 / 3 of the radius of the main pipe to facilitate the processing of the ventilation pipe.

通风91在线视频观看系统巧妙设计可大大减少排气阻力，使用效果也会更好，所以设计通风91在线视频观看师要注意细节问题！

Ventilation duct system ingenious design can greatly reduce the exhaust resistance, the use effect will be better, so the designer of ventilation duct should pay attention to the details!
