通風(fēng)管道生活中到處都能看到，但通風(fēng)管道看著簡簡單單，實際每個都是由不同的功能組成的，下面就是看看，通風(fēng)管道是怎么組成的。

Ventilation ducts can be seen everywhere in daily life, but they may seem simple, but in reality, each one is composed of different functions. Let's take a look at how ventilation ducts are made up.

1、通風(fēng)管道。在通風(fēng)系統(tǒng)中，依靠通風(fēng)管來送入或抽出空氣。通風(fēng)管的截面有圓形和矩形。通風(fēng)管除直管外，由彎頭、來回彎、變徑彎，三通、四通等管件按工程實際需要組合而成。

1. Ventilation ducts. In a ventilation system, air is drawn in or out through ventilation ducts. The cross-section of ventilation ducts can be circular or rectangular. Ventilation pipes, in addition to straight pipes, are composed of elbows, back and forth bends, variable diameter bends, tees, crosses, and other pipe fittings combined according to the actual needs of the project.

2、各類風(fēng)口。為了向室內(nèi)送入或室內(nèi)排出空氣，在通風(fēng)管上設(shè)置的各種型式的送風(fēng)口或吸風(fēng)口，以調(diào)節(jié)送入或吸出的空氣量。風(fēng)口的類型很多，常用的類型是裝有網(wǎng)狀和條形格柵的矩形風(fēng)口，設(shè)有聯(lián)動調(diào)節(jié)裝置，其他的類型沒有聯(lián)動調(diào)節(jié)裝置。風(fēng)口分為單層、雙層、三層及不同形式的散流器。

2. Various types of air vents. Various types of air supply or suction ports are installed on ventilation ducts to regulate the amount of air that is supplied or drawn into or out of the room. There are many types of air vents, with the commonly used being rectangular vents equipped with mesh and bar grilles, with linkage adjustment devices, while other types do not have linkage adjustment devices. The air outlet is divided into single-layer, double-layer, three-layer, and different forms of diffusers.

3、閥門。安裝于風(fēng)管上的用以調(diào)節(jié)風(fēng)量和關(guān)閉個別支管的通風(fēng)部件。通風(fēng)與空調(diào)工程常用的閥門有插板閥、蝶閥、多葉調(diào)節(jié)閥、圓開瓣式啟動閥、空氣處理室中旁通閥、防火閥和止回閥等，

3. Valves. Ventilation components installed on air ducts to regulate air volume and close individual branch pipes. The commonly used valves in ventilation and air conditioning engineering include plug valves, butterfly valves, multi blade regulating valves, circular opening type starting valves, bypass valves in air handling rooms, fire dampers, and check valves,

4、消聲器。防止噪聲傳入室內(nèi)所采用的裝置。在空調(diào)工程中采用的有阻性捎聲器、抗性捎聲順、共振性消聲器和寬頻帶復(fù)合式消聲器等。

4. Silencer. The device used to prevent noise from entering indoors. Resistive silencers, resistant silencers, resonant silencers, and wideband composite silencers used in air conditioning engineering.

5、除塵器。是凈化空氣的一種設(shè)備，一般分為旋風(fēng)式除塵器、濕式除塵器和袋式除塵器等。

5. Dust collector. It is a device for purifying air, generally divided into cyclone dust collector, wet dust collector, bag filter, etc.

6、通風(fēng)機(jī)。是機(jī)械通風(fēng)系統(tǒng)中迫使空氣流動的機(jī)械。通風(fēng)機(jī)是通風(fēng)與空調(diào)系統(tǒng)的主要設(shè)備，根據(jù)構(gòu)造原理分為軸流式通風(fēng)機(jī)和離心式通風(fēng)機(jī)兩類。

6. Ventilation fan. It is a mechanical device in a mechanical ventilation system that forces air flow. Ventilators are the main equipment of ventilation and air conditioning systems, which are divided into two categories based on their construction principles: axial flow fans and centrifugal fans.

7、風(fēng)帽。它用于排風(fēng)系統(tǒng)的末端，它的作用是向室外排除污濁空氣。按其形式分有：適用于一般機(jī)械排風(fēng)系統(tǒng)的傘形風(fēng)帽，適用于除塵系統(tǒng)的錐形風(fēng)帽，適用于自然排風(fēng)系統(tǒng)的簡形風(fēng)帽

7. Wind hat. It is used at the end of the exhaust system to remove polluted air from the outside. According to their forms, there are umbrella shaped air caps suitable for general mechanical exhaust systems, conical air caps suitable for dust removal systems, and simplified air caps suitable for natural exhaust systems
