2、阀门。安装于风管上的用以调节风量和关闭个别支管的通风部件。通风与空调工程常用的阀门有插板阀、蝶阀、多叶调节阀、圆开瓣式启动阀、空气处理室中旁通阀、防火阀和止回阀等
2. Valve. Ventilation components installed on the air duct to adjust the air volume and close individual branch pipes. Valves commonly used in ventilation and air conditioning engineering include plug valve, butterfly valve, multi leaf regulating valve, round open disc start valve, bypass valve, fire damper and check valve in air treatment room
3、消声器。防止噪声传入室内所采用的装置。在空调工程中采用的有阻性捎声器、抗性捎声顺、共振性消声器和宽频带复合式消声器等。
3. Muffler. A device used to prevent noise from entering the room. In the air conditioning project, the resistive sound carrying device, resistant sound carrying device, resonant muffler and broadband composite muffler are used.
