DN50-2000mm Diameter Round Fire Damper Manufacturers Of Laboratory Ventilation System The air volume control valve has the following characteristics: 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 constant air volume regulator 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.

Features of air volume control valve:
1. Pressure independent control: the valve body in the valve body to install mechanical pressure compensation components, according to the air inlet and outlet pressure pressure for automatic pressure compensation to ensure that the wind valve in the static pressure changes to maintain a constant set of air flow; Pressure drop 150Pa ~ 750Pa within the scope of pressure to achieve independent control;
2. Accurate air flow control: through the air flow speed controller component positioning, air volume can be quickly adjusted, air volume control accuracy of ± 5%;
3. Air volume adjustment control range: air volume 50m3 / h ~ 1100m3 / h;
4. Fast response: response time to control signal and duct static pressure change: <1 second;
5. Anti-dust, maintenance-free: Compared with the conventional butterfly valve similar products, because this series of products without air flow (or pressure) sensor, so the sensor caused by dirty plug system failure caused by security incidents, improve product stability And durability.
6. highly anti-corrosion treatment: the use of PP plastic body material, is the product can be high-intensity corrosion conditions in the long-term safe operation;
7. Control mode switching and remote communication function: This product selection PLC programmable controller, with control mode switching function (software with a variety of operating modes, just set to change the valve running control state) and remote communication function.
8. High reliability, high quality price, courteous service: domestic quality products, reliable operation, quality and cheap, provide 24-hour service.

Material and advantages of PP duct valve

The so-called PP pipe actually refers to the material made of polypropylene, which is mainly used in the indoor cold and hot water supply system of buildings. Compared with other materials of pipes, it has good advantages:

1. No corrosion: PP duct valve can withstand the PH value in a wide temperature range, ranging from 1 to 14 high acid and alkali corrosion concentrations.

2. Wear-resistant and non-scaling: PP pipe valves and pipe fittings have a uniform and smooth inner walls, with low flow resistance and no scaling.

3. Reduce vibration and noise: PP pipe valve has excellent sound insulation performance, which can significantly reduce vibration and noise caused by liquid flow.

4. Anti-freeze cracking: PP material has excellent elasticity so that the pipes and pipe sections can expand with the frost heaving liquid without cracking. 5. Anti-condensation, low heat loss: PP material is a poor thermal conductor, reducing condensation and reducing heat loss.

11. Simple installation: PP pipe valve is light in weight, easy to install and operate, and has weldability.

What material is the main material of the PP duct valve

PP duct, glass fiber reinforced polypropylene pipe. Specializing in the production, sales, and installation of FRPP ducts, the raw materials are pure and no return material is added, the equipment is advanced, and the technology is sophisticated. The FRPP ducts produced have smooth inner and outer walls, uniform texture, low fluid resistance, and strong ventilation; acid and alkali resistance, corrosion, and temperature resistance It has stable performance prevents secondary chemical reactions between the medium in the tube and the tube body, and reduces the difficulty of purification of industrial waste gas and liquid; it is non-toxic and tasteless, environmentally friendly and hygienic, non-scaling and non-bacterial, suitable for process pipelines in the food industry. Air ducts are pipes used for air transportation and distribution. In the chemical, food, and other industries, the requirements for ventilation duct systems are getting higher and higher. Metal ducts are far behind plastic ducts in terms of chemistry, hygiene, and economic efficiency. PP air ducts are widely used in the purification treatment of acid mist, alkali mist, alkaline waste gas, and organic waste gas in chemical, chemical fiber, textile, pharmaceutical, and other industries.

Classification of PP duct valves

1. One-time regulating valve: If the system is not balanced, it is a regulating valve designed to achieve the required air volume. It is divided into flapper valve, butterfly valve, multi-leaf regulating valve, and three-way valve.

2. Frequently switched regulating valves: Mainly include fresh air valve, primary and secondary air return valve, exhaust valve (including exhaust valve for comprehensive exhaust and partial exhaust).

8. Automatic control valve: Mainly used for automatic adjustment of fresh air, primary return air, and secondary return air. In addition to meeting the requirements of frequently-on-off regulating valves, it should also have good regulating characteristics.

Features:

It is mostly used in cold air or hot air gas pipelines in ventilation and environmental protection projects. The specific industries are chemicals, building materials, power stations, glass products, etc. The sealing ring of the electric air valve is tightly processed with the same high-strength material as the valve body, which has good stability. It also has the advantages of simple structure, small operating torque and light weight, and the characteristics of rapid opening and closing, flexible actions, small operating torque, and large flow capacity are also one of the reasons for the good response of users. It can be applied to the control and adjustment of dust, flue gas, air, and fluids containing suspended particles and thick and turbid and slurry fluids, so it can be regarded as a powerful and practical component in industrial control components.
