Qingdao Shina machinery production of direct discharge valve is divided into carbon steel, stainless steel two materials. Beautiful shape, small volume plate thick, seam welding is fine, wind locking effect is good, will not produce lax closure and other conditions leading to powder leakage.

The principle of discharge valve is to use turbomachinery rotation to realize quantitative feeding and discharging, which not only plays the role of conveying materials but also bears the role of sealing. When the material in the upper silo falls by its own weight and fills the gap between the blades, it is uniformly discharged with the rotation of the blades, and the discharge quantity is controlled by the frequency converter to control the speed of the motor.
