Overview

Air volume regulating valve, also known as air damper, is an indispensable central air conditioning terminal accessory in ventilation, air conditioning, and air purification projects of industrial plants and civil buildings. It is generally used in air conditioning and ventilation system ducts to regulate the air volume of branch pipes, and can also be used for mixed regulation of fresh and return air.

Product Details

1、 Characteristics of air volume regulating valve

1. The size of the connecting pipe for the multi blade air volume control valve is the same as the rectangular duct size specified in the national ventilation duct standardization.

2. The blades of the air volume regulating valve are split and open, and are used as regulating valves in ventilation, air conditioning, and air purification systems.

3. Through experimental testing, it has been determined that the air tightness of the air volume regulating valve is good, with a relative air leakage rate of about 5% and good regulating performance.

2、 Structural characteristics of air volume regulating valve

1. The air volume regulating valve has four uniform specifications for blade width, with diamond shaped double blades and soft overlapping between blades, resulting in good sealing performance.

2. The valve body frame of the air volume regulating valve is cold-rolled from 2mm galvanized sheet and welded with carbon dioxide gas shielding or processed and welded from ordinary Q235 sheet; The blades are cold-rolled into corrugated shapes using 1mm galvanized sheet, with two pieces of composite spot welded square shafts, or 2mm G235 steel plate cold pressed into shape, and a single piece punched square shaft or welded round shaft.

3. The regulating valve is divided into manual and electric types, based on the materials used: iron plate, galvanized plate, aluminum alloy plate, and stainless steel plate. The valve body structure and specifications are the same.

3、 Scope of application of air volume regulating valve

Widely used in industrial, mining, and civil building HVAC systems to regulate air flow, it is one of the key equipment for controlling ventilation modes in various environments. Its main characteristics are flexible operation, low noise, small leakage, wide working temperature range (sealed leakage<0.5%), reliable structure, and safety and convenience.

4、 Types of air volume control valves

Air volume control valves are generally divided into the following types: multi leaf control valves, butterfly valves (single leaf control valves), and forward opening control valves.
