The drainage ventilation pipe system includes types such as extension ventilation pipe, main ventilation pipe, auxiliary ventilation pipe, combined ventilation pipe, circular ventilation pipe, appliance ventilation pipe, converging ventilation pipe, and ventilation pipe, which are used in different positions. Among them, the hood type ventilation pipe is suitable for installation in water storage tanks and water tanks.
A pipeline connected to the atmosphere that is set up to ensure air circulation, pressure stability, and seal failure in the drainage system.
Performance of bent ventilation pipe:
1. Discharge the gas inside the drainage pipeline to meet hygiene requirements;
2. The ventilation pipe replenishes fresh air into the reservoir, water tank, and drainage pipeline to reduce corrosion of metal pipes and extend their service life;
3. Reservoirs and water tanks should be equipped with at least two ventilation pipes to improve the drainage system's capacity, prevent the formation of stagnant water, cross contamination, reduce pressure fluctuations, protect water seals, and prevent water seal damage;
4. It can effectively discharge the water vapor and gas in the reservoir and water tank, and the built-in gauze mesh can prevent vectors, insects, and dust from entering and damaging the water quality.
Description of bent ventilation pipe:
1. The average flow velocity of the gas in the filter (mesh, cloth) layer of the ventilation pipe design is 0.75m/s. When installing the filter cloth, equivalent materials should be used for stitching, and the inner cover can be made of non-metallic materials;
2. The ventilation pipe is designed with three thicknesses of soil cover (H1): 0.0m, 0.5m, and 1.0m. 0.0m is suitable for southern regions, 0.5m is suitable for central regions, and 1.0 is suitable for cold regions;
3. Rust removal after welding, required to be made according to customer design requirements;
4. In areas where conditions permit, stainless steel materials can be used according to design requirements to achieve good performance and extend service life.
