Once the plastic dampers in normal operation have abnormal conditions, it will bring a lot to the production process of the application scenarios. The impact is precisely because so many users who purchase plastic air valves are extremely concerned about the problems related to the use of air valves. So what issues should be paid attention to when using plastic air valves? The following is a summary of the details that need to be paid attention to when using plastic air valves:

First of all, pay attention to the problem of protecting the outer surface of the damper

It is difficult to distinguish PP plastic air valve from ordinary valves only from the working principle and appearance structure of PP plastic air valve, but the plastic air valve can be distinguished well according to the different materials of manufacture. If the outer surface of the air valve is damaged or worn, it may affect its excellent use effect. Therefore, when using the plastic air valve, the outer surface of the air valve must be protected in place to avoid damage to the outer surface. To the normal production of the enterprise.

Secondly, the environment around the application scene should be controlled in a state suitable for the operation of the air valve

Combining many cases of using polypropylene plastic air valve, it can be found that the simple structure of the air valve actually has high requirements for the environmental conditions of the application scene. If an index in the application scene exceeds the index suitable for the normal operation of the air valve It may cause damage to the air valve. Therefore, even if the price of plastic air valves purchased in large quantities is favorable, we must strictly monitor the surrounding environmental conditions, and try to control all the indicators in the environment where the air valve is located in a state that can play a good use effect.

The above summary of several issues that need to be paid attention to when using PP plastic air valves is here for the time being. I have to admit that with the assistance of plastic air valves, the media flow in many application scenarios has become more controllable, so when companies use polypropylene plastic air valves, they must pay more attention to these details and strive to make the air valve fully functional. The desired effect.

Although the small PP pipe is inconspicuous, it plays a vital role in home decoration. People are very concerned about the material of PP air pipe valves, so what materials are used for PP air pipe valves on the market now? The following editor will introduce you to the relevant information about PP air pipe valves.

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).

3. 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.

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.

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