The discharge valve, also known as the star-shaped ash discharge valve, impeller feeder, or airlock, can be classified into rigid and elastic types based on the blades. It is a crucial component in mechanized and automatic control systems for uniform and continuous batching, conveying, and discharging of materials. Relying on the gravitational force of the material and the forced action of the discharge valve's working mechanism, it discharges materials stored in the silo and continuously and evenly feeds them into the next device.

Characteristics of the Discharge Valve

◇ Compact structure, small size, high processing capacity, and easy maintenance and operation.

◇ Special structural design and manufacturing process achieve excellent air sealing performance.

◇ Suitable for various loose, non-sticky dry materials, with round or square inlet and outlet.

◇ Quantitative feeding (or discharging) of powder materials can be used in pressure-type or suction-type pneumatic conveying systems.

◇ Depending on the material properties, it can be equipped with explosion-proof motors, variable frequency speed control motors, or electromagnetic speed control motors, etc.

◇ Each piece undergoes turning, milling, and assembly to ensure high-precision air sealing and feeding/discharging performance.

◇ Specially designed shaft seals (gland type, mechanical type, gas seal, etc.) are suitable for different working conditions.
