As we all know, everything should be analyzed in detail. The same is true in the design of ventilation ducts. The design of ventilation ducts should be combined with practice. A friend will ask, ventilation pipes directly buy ready-made general, why should they be designed separately? Today, Xiaobian will give you an analysis of ventilation pipes design combined with practical reasons, hoping to help you.
1. Steam or other water-bearing gas pipes are equipped with drainage pipes or traps at low points, and some ventilation pipes are equipped with air-water separators to drain water in time to prevent water hammer and obstruct gas flow in pipes. In order to exclude condensate water, steam and other water-bearing gas pipelines should have a certain gradient in the design of ventilation pipelines, generally not less than two thousandths. For underground drainage pipelines using gravity flow, the slope is not less than five thousandths. Feed water or other liquid pipes are equipped with exhaust devices at high points to remove air or other gases accumulated in the pipes, so as to prevent air resistance from causing abnormal operation.
2. Pipelines on the ground should avoid crossing roads, railways and waterways as far as possible. When crossing is unavoidable, the crossing height should also enable pedestrians and vehicles to pass through. When designing ventilation pipelines, underground pipelines are generally laid along roads, and proper distances between various pipelines are maintained for installation and maintenance.
3. In order to ensure the strength and stiffness of the ventilation pipeline, a variety of brackets (suspension) are set up, such as movable bracket, fixed bracket, guide bracket and spring bracket. The bracket is set according to the pipe diameter, material, pipe wall thickness and load conditions.
The above is a small edition of ventilation ducts for you to introduce the design of ventilation ducts combined with the actual situation, if you want to know more about the processing of ventilation ducts, please pay attention to our website, you can also telephone consultation, we will serve you wholeheartedly, looking forward to your presence!
