Introduction to air regulating valve: Selection of air regulating valve: Commonly used air regulating valves in heating, ventilation and air conditioning systems include single leaf air valves and multi leaf air valves
Selection of regulating air valve: The commonly used regulating air valves in heating, ventilation and air conditioning systems include single leaf air valves and multi leaf air valves. Multi blade air valves can be divided into parallel blade air valves, split blade air valves, compound air valves, and diamond shaped air valves, while single blade air valves can be divided into butterfly valves and single blade diamond shaped air valves. Diamond shaped air valve is a relatively new type of air valve that uses changing the angle of the diamond shaped blades to alter the flow
Quantity has the advantages of reliable operation, convenient adjustment, and low noise, but the structure is complex. Flat type, split type multi blade regulating valves and butterfly valves all regulate air flow by changing the blade angle. The valve capacity of the flat blade air valve is 0.5, and the valve capacity of the split multi blade regulating valve is 0.1. From the perspective of reducing noise and energy loss, the split blade air valve is superior to the parallel blade air valve. However, in the actual design and selection process, it is necessary to consider the pipeline system and the equipment connected to it to make a reasonable choice.
