With the rapid development of economy, ventilation duct is more and more widely used in life. For example, in restaurants, ventilation equipment provides customers with an excellent dining environment and makes people eat happily in restaurants. For example, mining in industrial production requires excellent ventilation conditions to ensure the respiratory health of miners. Ventilation equipment has been paid more and more attention. The planning and installation of ventilation duct is one of the important parts of ventilation equipment. Let's take a look at some points that should be paid attention to in ventilation duct planning.
1. It is mainly drawn according to the ventilation duct of a certain system and a certain floor, and the interface orientation is indicated.
2. Ventilation duct planning shall be numbered from the starting point. The starting point is generally the interface orientation, with the same section specification, the same length and the same section number. In addition, it shall be numbered in order. It is convenient to arrange production and construction.
3. The orientation of supports and hangers shall be indicated during ventilation pipe planning, and the orientation distance and material specification of supports and hangers shall meet the requirements of later specifications and process specifications.
4. When planning ventilation pipes, elbows and reducers should be considered first to meet the requirements of the length of concentric elbows and reducers on the inside and outside.
5. The pipe diameter planning orientation, elbow orientation and pipe bottom elevation shall be indicated.
