According to the positive pressure air supplier, the main purpose of multi-leaf air supply is to bring fresh outdoor air into the indoor environment easily. So when a fire occurs in the place where people live and deal with it, according to the current facilities, it can not only ensure smooth, fresh air passage and some smoke and CO environment, but also dilute toxic substances according to the flow of fresh air, so as not to disturb people trapped in the presence of gases, so as to facilitate people to escape in the fire.
Positive pressure air outlet is suitable for high-roof high-efficiency air or local cooling places, such as airport waiting room, indoor gymnasium, hotel kitchen and other places, which have the advantages of large induction ratio and fast wind speed reduction. In a large space ventilation system, it can be used as large air volume. In order to reduce multi-leaf air outlet, large temperature difference air supply can be installed on the ceiling or roof, and can be used to low meters, or two. Huge height of air supply, even up to the height of more than meters.
The main components of positive pressure air supply outlet are valve body, valve, bushing, thin actuator, grille, etc. In this case, the valve body and disc are the key components that need to be identified: the valve body is the main component of the valve; according to the pressure level, there are different mechanical manufacturing processes. Valve positive pressure air outlet is strongly influenced by fittings, so it should be applied to the design stipulated in the following standards: the design of valve plate must meet the requirements of compressor manufacturers with various rules, the material of valve plate must be precisely stamped, between valve and seat, and good sealing must be ensured, besides still ensuring stable performance for a long time, greater flexibility and restoring material.
Normally, we know that when installing positive pressure air outlet in the clean room, we must achieve the required equipment is effective positive pressure multi-purpose air outlet flanging and ceiling sealing pad treatment between joints, remember that cracks in the local need to be carefully dealt with. To avoid damage of high-efficiency positive pressure multi-blade air supply outlet or coating, no device should be implemented. The positive pressure multi-blade air supply outlet device and air duct must be carefully connected, and the end of the outlet should be sealed with plastic film and tape.
Positive pressure air outlet is widely used in HVAC systems of industrial and mining buildings. It can accurately coordinate fresh air flow and is one of the key facilities to manage ventilation modes in various environments. Its main advantages are flexible operation, low noise, less leakage, (sealing leakage < 0.5%) wide operating temperature range, reliable components, fast and convenient.
