VAV variable air volume butterfly valve is an air-conditioning system that controls the temperature of an air-conditioned area by changing the air supply volume and also adjusting the air supply temperature. The system adjusts the air volume sent into the room through the variable air volume terminal device, and adjusts the air volume of the air conditioner accordingly to adapt to the air volume demand of the system.
The variable air volume butterfly valve can automatically adjust the air supply air volume of the air conditioner (adjust the air supply temperature when the air volume reaches a small amount) according to the change of the air conditioning load and the change of the indoor required parameters to meet the comfort requirements of the indoor personnel or other process requirements. At the same time, the speed of the blower is automatically adjusted according to the actual air supply volume, which reduces the power of the blower to a greater extent and saves energy.
VAV variable air volume butterfly valve contains the following components:
Controller (equivalent to the brain), angle actuator, linear stroke actuator, displacement sensor, electric door motor, anti-pinch infrared sensor, personnel area detector, foot switch, flow sensor, face wind speed sensor, temperature sensor, LCD display operation panel, lighting and other components.
Scope of application of vav variable air volume butterfly valve
Butterfly valve (mainly composed of valve body, valve stem, butterfly plate and sealing ring) is a simple regulating valve, and it can also be used for on-off control of low-pressure pipeline media. Ventilation butterfly valve is a non-closed butterfly valve. Ventilation butterfly valves are used in dusty cold air or hot air gas pipelines of ventilation and environmental protection projects in chemical, building materials, power stations, glass and other industries, as a gas medium to adjust the flow (unit: cubic meters per second) or cut off the pipeline control device. This type of valve should generally be installed horizontally in the pipeline.
Structural characteristics of vav variable air volume butterfly valve:
1. It is designed and manufactured by adopting a new structural form of welding of center-line disc plate and short structure steel plate, compact structure, light weight, easy to install, small flow resistance, large circulation, avoiding the influence of high temperature expansion, and easy to operate
2. There are no connecting rods, bolts, etc. in the air volume regulating valve, which is reliable in operation and long in service life. It can be installed in multiple positions, and is not affected by the flow of the medium. There are no connecting rods, bolts, etc., so it works reliably and has a long service life. It can be installed in multiple positions, and is not affected by the flow of the medium.
