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.

　　正壓送風口適用于高屋頂空氣或局部冷卻的地方,例如機場等候室,室內體育館,酒店廚房和其他地方有感應比例大,風速降低快的優勢,在一個大空間通風系統可以用作大風量,大溫差送風為了減少多葉送風口,安裝在天花板或屋頂,可用到米低的地方，也可以用兩個巨大的高度供氣，高度甚可以達到米以上。

　　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.

　　正壓送風口的主要部件有閥體、閥門、襯套、薄執行機構、格柵板等。在這種情況下，閥體和閥瓣是需要明確的關鍵部件:閥體是閥門的主要部件;根據壓力等級，有不同的機械制造工藝。閥正壓送風口由配件的強烈影響,因此應該適用于以下標準規定的設計:閥板的設計必須滿足各種各樣的規則的壓縮機制造商,閥板材料必須精密沖壓、閥和閥座之間,必須保證良好的密封,除了仍然要保證性能穩定很長一段時間,更大的靈活性和恢復材料。

　　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.

　　在正常情況下,我們了解到,在潔凈室安裝正壓送風口,我們必須達到規定的設備是有效的正壓多用送風口翻邊和關節之間的天花板板密封墊,記住,有裂縫在當地需要認真處理。避免正壓多葉片送風口損壞或涂層損壞不應實施裝置，正壓多葉片送風口裝置與風管必須認真連接，口端用塑料薄膜和膠帶加強封閉處理。

　　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.

　　正壓送風口廣泛應用于工礦民用建筑暖通空調系統中，能精確協調新風流量，是實現各種環境下管理通風模式的關鍵設施之一。其主要優點是工作靈活，噪音低，泄漏量少，(密封泄漏< 0.5%)工作溫度范圍廣，部件可靠，快捷方便。

　　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.
