通风防排烟设备在运转工作的时期，首次就是将外面的空气顺利的送到室内中。这样当在不少日常生活或者制造场所中产生了 火灾的环境下，人士依照这种部件不仅仅肯定要担保楼道中的空气贯通，况且在不少具有浓烟或者一氧化碳的环境中，这种 部件还肯定要依照空气贯通来稀释这个含毒气体，不至于使被困人士被毒气所困扰，有好处人士在火灾中逃生。
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.
通风防排烟设备适当高大层顶牢靠送风或配件供冷的部位，如机场大厅，户内体育场，旅店厨房等部位有诱导比大，风速 衰减快的亮点，在空调透风编制中可有用相当大的风量，大温高温差送风以减少消防检查通风防排烟设备概率，安设处处天棚或屋顶棚上 ，可用于米内低环境，也可用种特别大面积送风，特别甚至可达到米以上。
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.
通风防排烟设备的首次构成适宜有是阀体、阀片、轴衬、薄型操控、格栅面板。而这边其内阀体和阀片是大家需要 清楚的紧要重要适宜：阀体是阀门中的一个首次零部件；依据张力级数有不同的机械制造方式。阀片是通风防排烟设备运行时受 冲击力强的适宜，所以在设置中要符合下面的要求：阀片的设置明白获取压缩机制造商的各种要求，阀片用料必须慎密品管，同时阀片和阀座之间的需要用到担保密封良好，况且并且还要担保每天安稳的效应，以及用料的弹和恢复性。
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.
