安装在通风空调系统的送、回风管路上，起防烟阻火的作用。
通常分为电动式和手动式两种，相同点是其平时工作均呈常开状态，熔断关闭温度均为70℃，风阀均可调节开度;不同点是动作方式和复位方式，电动式是通过输入的电信号(DC24V)，执行机构内的电磁铁通电动作，阀门自动关闭;手动式是手动关闭或70℃熔断器动作关闭。
按其用途又可分为防火阀和防火调节阀。相同点是其熔断。
关闭温度均为70℃，一般产品均可手动关闭。不同点是防火调节阀用于有防火要求且需要调节风量的风管系统中，具有手动关闭、手动复位、电动关闭、电动复位、电信号输入输出与风机连锁等功能。
（4）排烟防火阀
排烟防火阀安装在单独排烟或排风、排烟合用的系统中，平时工作呈常开状态，火灾时当管道内烟气温度达到280℃时熔断关闭。
具体应用中排烟防火阀的常开、常闭设置要求，还得依据排烟口的形式而定。如果排烟口是常闭的，那么就应该设常开的排烟防火阀，如果排烟口是常开的，那么就应该设常闭的排烟防火阀，如果排烟口设置的是带防火阀的专用排烟口，那么排烟支管上就不再设排烟防火阀。

5.The air outlet is the most terminal product in the central air conditioning system, mainly playing a role in regulating the airflow direction, forming an air cycle, and ensuring air quality. is an important part. According to the material, it is divided into: stainless steel/aluminum alloy/iron plate; according to the system, it is divided into: air/return air/new air. The air outlet plays a crucial role in the air conditioning system. According to different application scenarios and functional needs, the air outlet can divided into several types.
Here are several common classifications of air outlets and their characteristics:
1) Venetian blind air outlet The Venetian blind air outlet is most common type of air outlet, including single-layer Venetian blind air outlet, double-layer Venetian blind air outlet, electric Venetian blind air outlet, fixed oblique Venetian blind air outlet. They are usually used for side supply in all-air air conditioning systems and are suitable for general air conditioning engineering and comfort air conditioning.
2) Diffuser Diffusers include rectangular diffusers, round diffusers, disk-shaped diffusers, and other forms. They are suitable for ceiling installation and can supply air, often used in cinemas, libraries, shopping malls, etc.
3) Jet outlet air inlet The jet outlet air inlet includes round, spherical, and spherical forms, which are suitable for long-distance air supply and are often used in airports, stadiums, and other large public places.
4) Slot air inlet The slot inlet sends air through a narrow linear outlet, which is suitable for airports, hotel lobbies, etc.
5) Rotary air inlet The rotary air inlet can induce large amount of surrounding air to mix with it and then supply it to the working area. It is suitable for exhibition halls, computer rooms, and other places that require efficient air mixing
6) Hole plate air inlet The hole plate air inlet sends air through a small hole-shaped comprehensive plate or local plate, which is suitable for constant temperature rooms, clean, and other environments that require precise temperature control.
7) Stainless steel air inlet Stainless steel air inlets are widely used in operating rooms of hospitals,ification and dust removal workshops, electronic factories, chemical factories, etc., which require aseptic, dust-free, and corrosion-resistant places, with the characteristics of durability corrosion resistance, and high temperature resistance.
Damper valves are widely used in industrial and architectural environments. Here are some common types of air outlets their characteristics:
Manual regulating valve Currently, the most commonly used in engineering is the butterfly regulating valve, which is used to manually adjust and distribute the air volume branch pipes in the air duct system. It does not require remote self-control and can meet the requirements of system air volume distribution through initial balancing adjustment. Its application is relatively.
Electric regulating valve Installed on the air duct of the air conditioning and ventilation system, it is used to adjust the air volume of the branch pipe and can be used for the mixing adjustment of fresh air and return air. The electric valve is used to open or close the valve, and the output is an open-close electrical signal. is matched with the self-control system to automatically control and adjust the air volume. The electric actuator should have the functions of remote electric control and on-site manual control, it should be equipped with a manual/electric operation conversion handle, with both mechanical and electrical limit devices, and it should also have the functions of electric control start and stop, manualautomatic conversion, fault alarm, and start and stop status feedback.
Smoke and fire damper Installed on the supply and return air ducts of the ventilation air conditioning system, it plays a role in smoke prevention and fire resistance. It is usually divided into electric type and manual type. The same point is that they are both normally, and the fusing closing temperature is 70℃. The air valve can adjust the opening; the difference is the action mode and reset mode. The electric type is through input electric signal (DC24V), the solenoid valve in the actuator is energized to act, and the valve is automatically closed; the manual type is closed or closed by the 70℃ fuse. According to its use, it can also be divided into fire damper and fire regulating damper. The same point is the fusing closing temperature is 70℃, and the general products can be manually closed. The difference is that the fire regulating damper is used in the air duct system requires fire protection and needs to adjust the air volume, and it has the functions of manual closing, manual reset, electric closing, electric reset, electric signal input and output linked with fan, etc.
Smoke exhaust and fire damper The smoke exhaust and fire damper is installed in a separate smoke exhaust or exhaust and smoke exhaust combined system It is normally open and fuses and closes when the smoke temperature in the pipeline reaches 280℃ in a fire. In specific applications, the normally open and normally settings of the smoke exhaust and fire damper should still be determined according to the form of the smoke outlet. If the smoke outlet is normally closed, then a normally open smoke and fire damper should be set. If the smoke outlet is normally open, then a normally closed smoke exhaust and fire damper should be set. If the smoke outlet is set a dedicated smoke outlet with a fire damper, then the smoke exhaust branch pipe will no longer be provided with a smoke exhaust and fire damper.
