As a kind of environmental protection equipment, discharge valve is widely used in cement, road construction, metallurgy, chemical industry, food, drying equipment and other industrial projects. So it is also called a discharger.

Working principle

1. discharge valve, also known as ash discharge valve, rotary feeder, lock valve. The structure of the discharge valve is usually composed of a rotor impeller with several blades, a casing, a seal, a reducer, and a motor.

2., when the material in the upper silo falls and fills the gap between the blades by its own weight. With the rotation of the blade and discharge in the lower part, therefore, the discharger can be quantitative and continuous discharge.

3.discharge valveCommonly used in bulk materials, particles and powder material transport, for the pressure output system or negative pressure output system, discharge valve can be uniform, continuous feeding to the pipe. In order to ensure that the material in the output pipe is relatively stable, so that the bulk material transportation can work normally. At the same time, but also the discharge valve, the lower air pressure partition and play the role of air lock. Therefore, the discharge valve is an important component commonly used in pneumatic conveying system.

The upper and lower flange ports of the 4. discharge valve are basically square or round, and can also be selected by the user.

5. wear-resistant closed rotor impeller This type of discharger is characterized by the end of the rotor blade lined with polyvinyl fluoride sealing strip or wear-resistant nitrile sealing strip to ensure good contact between the end of the blade and the inner wall of the shell. And after wear, the blade end can be easily adjusted, so that it is still in good contact with the inside of the shell, and has better sealing performance.

6. high temperature resistant type, the temperature of the material transported by it can reach 280 ℃, and the bearings and impellers at both ends are isolated to a certain extent. Can prevent ultra-fine powder and bearing contact, thereby reducing wear.

  discharge valveAs a simple and fast conveying equipment. Its stable performance, unanimously recognized by the majority of users.
