Ventilation, smoke prevention and exhaust equipment in operation period, the first time is to smoothly send the outside air to the indoor. In this way, when a fire occurs in many daily life or manufacturing places, people not only have to guarantee the air penetration in the corridor according to this component, but also in many environments with smoke or carbon monoxide, this component must dilute the poisonous gas according to the air penetration, so as not to make the trapped person troubled by the poisonous gas, which is beneficial to people. The taxi escaped in the fire.

　　通風防排煙設備適當高大層頂牢靠送風或配件供冷的部位，如機場大廳，戶內體育場，旅店廚房等部位有誘導比大，風速 衰減快的亮點，在空調透風編制中可有用相當大的風量，大溫高溫差送風以減少消防檢查通風防排煙設備概率，安設處處天棚或屋頂棚上 ，可用于米內低環境，也可用種特別大面積送風，特別甚可達到米以上。

　　Ventilation and smoke prevention and exhaust equipment suitable high-rise roof strong air supply or cooling parts, such as the airport hall, indoor stadium, hotel kitchen and other parts have high induction ratio, fast attenuation of wind speed highlights, in the preparation of air conditioning ventilation may have considerable air volume, large temperature difference air supply to reduce the probability of fire inspection ventilation and smoke prevention and exhaust equipment, installed in the ceiling or roof, may It can be used in low environment within a meter, and can also be used to supply air in a very large area, especially up to more than a meter.

　　通風防排煙設備的構成適宜有是閥體、閥片、軸襯、薄型操控、格柵面板。而這邊其內閥體和閥片是大家需要 清楚的緊要重要適宜：閥體是閥門中的一個零部件；依據張力級數有不同的機械制造方式。閥片是通風防排煙設備運行時受 沖擊力強的適宜，所以在設置中要符合下面的要求：閥片的設置明白獲取壓縮機制造商的各種要求，閥片用料必須慎密品管，同時閥片和閥座之間的需要用到擔保密封良好，況且并且還要擔保每天安穩的效應，以及用料的彈和恢復性。

　　For the first time, the suitable composition of ventilation and smoke prevention and exhaust equipment is valve body, valve sheet, shaft lining, thin control and grille panel. And here the inner valve body and disc are the most important and suitable parts that we need to know clearly: the valve body is the first part of the valve; according to the tension series, there are different mechanical manufacturing methods. Valve discs are suitable for ventilation, smoke prevention and exhaust equipment to be subjected to strong impact during operation, so the following professional requirements should be met in the setting: the disc setting clearly obtains the requirements of the compressor manufacturer, the disc material must be carefully managed, and the need between the disc and the seat should be used to ensure good sealing, and also to guarantee the effect of daily stability, as well as the elasticity and recovery of the material used. Renaturation.
