The air volume control valve is an indispensable part of the central air conditioning terminal in the ventilation, air conditioning and air purification works of industrial buildings. It is generally used in air conditioning and ventilation system piping to regulate the air volume of the branch pipe, and can also be used for the mixing regulation of fresh air and return air.

 
I. air volume Regulating valve Characteristics
 
(L) the size of the nozzle of the multi leaf vane control valve is the same as that of the rectangular duct used in the standardization of the national ventilation piping.
 
(2) the blade of the volume control valve is open and open, and is used as a regulating valve in ventilation, air conditioning and air purification systems.
 
(3) through the test, the air volume control valve has good tightness, the relative air leakage is about 5%, and the regulating performance is good.
 
Two. Structural characteristics of air volume control valve
 
(L) the volume control valve has four specifications in the width of the blade, the blade shape is a diamond double leaf, and the blade is soft lapped, so the sealing performance is good.
 
(3) the frame of the volume control valve body is made of cold rolled 2 mm galvanized sheet, which is welded by carbon dioxide gas protection or welding by ordinary Q235 plate. The blade is made of corrugated steel with 1 mm galvanized sheet, two pieces of synthetic spot welding plug shaft, or 2 mm G235 steel cold forming, single chip punching square shaft or welding shaft.  
 
(4) the control valve is divided into manual and electric parts. According to the materials used, it is divided into four types: iron plate, galvanized sheet, aluminum alloy plate and stainless steel plate.
 
Three. Application range of air volume control valve
 
It is widely used in HVAC system of industrial and mining buildings, and it is one of the key equipment to control air flow in various environments. Its main features are flexible operation, low noise, and small leakage. (closed leakages < 0.5%) the working temperature area is wide, the structure is reliable, and it is safe and convenient.
