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.

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.

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

The following accessories can be selected according to different controls and requirements:

Cut-off accessories: single solenoid valve, double solenoid valve, limit switch echo device.

Adjustable accessories: electric positioner, pneumatic positioner, electric converter.

Air source treatment accessories: air filter pressure reducing valve, air source treatment triple pieces.

Manual mechanism: HVSD manual mechanism

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.

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.

6. 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.

This valve is made of the same material as the valve body and processed into a sealing ring, which adopts electric or pneumatic transmission. The applicable temperature depends on the material selection of the valve body, and the nominal pressure is ??0.6MPa. Generally, it is suitable for industrial, metallurgical, environmental protection, and other pipelines for ventilation and media flow adjustment. Its main features are:

1. Novel and sound design, unique structure, lightweight, and rapid opening and closing.

2. Small operating torque, convenient operation, labor-saving and dexterous.

5. Use suitable materials to meet the requirements of low, medium and high medium temperatures and corrosive mediums.

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.

The above are the main functions and features of the air valve. There are also different types of air valve for different occasions and needs.

Air volume control valves are widely used in industrial, mining, and civil building HVAC systems, industrial waste gas purification systems, and are one of the key equipment to control ventilation modes in various environments.

Material and category

The common materials of the air volume control valve are PP material, stainless steel material, PP material, and galvanized steel plate. The most used in the industrial waste gas purification industry is the PP damper.

Common types of damper:

1. Split multi-leaf control valve

2.Butterfly valve (single leaf regulating valve)

3. Manual air valve

4. Electric air volume control valve

6. Airtight damper

(1) The air volume control valve has four specifications when the blade width is all the same. The blade shape is a diamond-shaped double blade, and the blades are soft overlapped, so the sealing performance is excellent.

(2) The valve body frame of the air volume dispatching valve is formed by cold rolling of 2mm galvanized sheet and then welded by maintenance welding of carbon dioxide gas or processed and welded from general Q235 sheet; the blade is cold-rolled with 1mm galvanized sheet into a corrugated shape, two pieces It is composed of spot welding inserting square shaft, or 2mm G235 steel plate cold forming, single-piece punching inserting square shaft or welding round shaft.

(3) The dispatching valve is divided into manual and electric. According to the materials used, it is divided into four types: carbon steel plate, galvanized plate, aluminum alloy plate, and stainless steel plate. The valve body structure and specifications are the same.
