Talk to you today: What are the components of the ventilation duct?

In daily life, there are everywhere pipes, and what to do is not very clear, ventilation pipes seem simple, in fact, each looks crude pipes, are composed of a number of different functions, to achieve the building's ventilation and associated needs, it is more convenient to use. Xiangzu HVAC professional ventilation duct, the individual components are also excellence, the following take a look at the ventilation duct consists of what parts.

1. Ventilation duct. In a ventilation system, ventilation ducts are used to bring in or take out air. The section of the ventilation pipe is round and rectangular. In addition to the straight pipe, the ventilation pipe is composed of elbow, back and forth bend, reducing bend, three-way, four-way and other pipe fittings according to the actual needs of the project.

2, all kinds of tuyere. In order to send air into or out of the room, various types of air supply or suction outlets are arranged on the ventilation pipe to adjust the amount of air sent into or sucked out. There are many types of tuyere, and the commonly used type is a rectangular tuyere equipped with a mesh and strip grating, with a linkage adjustment device, and other types have no linkage adjustment device. The tuyere is divided into single layer, double layer, three layer and different forms of diffusers.

3. Valve. A ventilation unit installed on an air duct to regulate air volume and close individual branches. The commonly used valves in ventilation and air conditioning engineering include slot valve, butterfly valve, multi-leaf regulating valve, round open flap starting valve, by-pass valve in air treatment room, fire valve and check valve, etc.

4. Muffler. A device used to prevent noise from entering a room. A resistive sound carrier, a resistant sound carrier, a resonant muffler and a wide band compound muffler are used in air conditioning engineering. 

5. Dust collector. It is a kind of equipment for purifying air, which is generally divided into cyclone dust collector, wet dust collector and bag dust collector.

6. Ventilator. A mechanical ventilation system that forces the flow of air. Ventilator is the main equipment of ventilation and air conditioning system, which is divided into axial ventilator and centrifugal ventilator according to the structure principle.

7. Cowl. It is used at the end of the exhaust system, and its role is to expel dirty air to the outside. According to its form, it is divided into: umbrella hood suitable for general mechanical exhaust system, conical hood suitable for dust removal system, simple hood suitable for natural exhaust system.
