(3) The dispatch valve is divided into manual and electric. The valve body structure and specifications are the same.

2.the characteristics of the Rectangular Motorized Duct Damper

(1) The takeover standard of the split multi-leaf air volume dispatching valve is the same as the rectangular air duct standard of the national ventilation duct standardization.

(2) The blades of the air volume dispatching valve are side-opening and forward-opening, which are used as dispatching valves in ventilation, air dispatching and air purification systems.

(3) According to the test, the air-tightness of the air volume dispatching valve is good, and its relative air leakage is about 5%, and the dispatching performance is good.

3.the scope of application of the Rectangular Motorized Duct Damper

It is widely used in industrial, mining, and civil building HVAC systems to accurately schedule air flow. It is one of the key equipment for controlling ventilation modes in various environments. Its main features are flexible work, low noise, small leakage, reliable structure, safety and convenience.

1. The role of water balance. The air volume distribution in various ventilation systems is reasonable, ensuring reliable fresh air distribution in different areas.

2. The function of energy-saving and precise control of air volume. On the premise of ensuring the fresh air volume, the system runs energy-saving and low-consumption

3. It is widely used in the industrial waste gas treatment industry, which can accurately control waste gas emissions and prevent the backflow of toxic waste gas.

4. The effect of reducing noise. It can effectively reduce wind noise and other noise in the air duct, especially in the exhaust system of industrial production and office buildings, replacing exhaust fans, significantly reducing noise, saving energy, and maintaining continuous ventilation.

The Air Highly Closed Check Valve with nothing to do with the pipeline pressure is used in the central fresh air system and exhaust system to effectively ensure the continuous new air volume and exhaust volume effectively and accurately control the air volume and reduce noise. They are usually used in a large area in the air duct system of the central fresh air system and exhaust system of hotels, hospitals, office buildings, and other places to replace traditional manual valves and exhaust fans.

The Air Highly Closed Check Valve has a range:

The Air Highly Closed Check Valve is suitable for industrial waste gas treatment, civil building HVAC systems, ventilation equipment in school laboratories, and hospital ventilation and exhaust systems. It is one of the vital equipment to control ventilation modes in various environments. Its main features are flexible operation, low noise, small leakage (closed type leakage> 0.5%), wide operating temperature range, reliable structure, safe and convenience.

1. It is designed and manufactured by adopting a new structural form of welding of mid-line disc plate and temporary structure steel plate. It has a compact structure, lightweight, easy installation, low flow resistance, large circulation, avoids the influence of high-temperature expansion, and is easy to operate.

2. 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 direction of the medium.

use:

This butterfly valve is a non-closed butterfly valve, which is widely used in the production process of building materials, metallurgy, mining, electric power, and other production processes on pipelines with a medium temperature of ≤300℃ and a nominal pressure of 0.1Mpa to communicate, open and close or adjust the amount of medium.
