Composition of ventilation ducts
In ventilation systems, tolerant ventilation pipes are used to feed or draw air. The cross section of the ventilation pipe is round and rectangular. In addition to the straight pipe, the ventilation pipe is made of elbows, back and forth bends, variable diameter bends, three-way, four-way and other pipe fittings according to the actual needs of the project.
Various tuyere
In order to send in or discharge air into the room, various types of air supply ports or air suction ports provided on the ventilation pipe are used to adjust the amount of air sent in or drawn out. There are many types of air outlets. The commonly used types are rectangular air outlets with mesh and strip grilles, equipped with linkage adjustment devices. Other types have no linkage adjustment devices. The tuyere is divided into single layer, double layer, three layer and different types of diffusers.
valve
Valves commonly used in ventilation and air-conditioning engineering include plug-in valves, butterfly valves, multi-leaf control valves, round flap start valves, bypass valves in air processing chambers, fire valves and check valves.
silencer
The resistance muffler, resistance muffler, resonance muffler and wide compound compound muffler used in air conditioning engineering.
dust collector
It is a kind of equipment for purifying air, generally divided into filter dust collector and electrostatic dust collector.
Ventilator
It is the machine that the compressed air flows in the mechanical ventilation system. Ventilator is the main equipment of ventilation and air-conditioning system. According to the construction principle, it is divided into axial flow fan and centrifugal fan.
Hood
It is used as the end of the exhaust system, and its role is to remove dirty air to the outside. According to its form: umbrella-shaped hood suitable for general mechanical exhaust system, conical hood suitable for dust removal system, simple hood suitable for natural exhaust system.
