Brief introduction of rotary valve:

Application in production: the rotary valve can be used in the material collection system as the discharger of the silo. The rotary valve is a commonly used discharging device in China, and is commonly used in the dust removal system as one of the important equipment of the dust removal system. It is especially suitable for dust and small particle materials. It is more popular in environmental protection, metallurgy, chemical industry, grain, cement road construction, drying equipment and other industrial projects.

Features of rotary valve:

1. Compact structure, beautiful appearance, easy to use.

2. Stable operation and low noise.

3. Due to the bearing, gearbox away from the shell for a certain distance, for high temperature, lubrication has been greatly improved.

4. It can be designed and manufactured according to user's requirements.

5. Before leaving the factory, the product is filled with special grease for cycloid reducer. Please check and refuel regularly. Rotary valve is commonly used in pneumatic output system. For pressure output system or negative pressure output system, the rotary valve supplies material to the conveying pipe evenly and continuously to ensure that the gas and solid in the pneumatic output pipe are relatively stable, so that the pneumatic conveying can work normally. At the same time, it can block the upper and lower air pressure of the discharger and play the role of air locking. Therefore, rotary valve is an important part in pneumatic conveying system.

Classification of rotary valves:

Rotary valve is divided into three types: common type, pressure resistant type and high temperature resistant type.

Common type: it can be used for common materials below 80 ℃ and normal temperature. It can continuously and evenly supply materials to the conveying pipe. In the system and separation dust collection part, it can also be used as a discharger.

Pressure type: it adopts closed rotor, which can be widely used in suction type, pressure type air conveying system and negative pressure conveying equipment. It can ensure that the air pressure in the conveying pipe does not leak, and it can safely transport and collect materials. Therefore, it is called ten thousand lock air machine in this aspect. It can not only withstand pressure, but also has common function.

High temperature resistant type: according to the different temperature rise of material conveying and blanking port, because the temperature has an impact on the expansion of the body, and is not conducive to the bearing and oil seal system.
