It is commonly used in chemical, metallurgical, food and pharmaceutical industries. It controls the flow of materials through a rotary valve. It has the characteristics of simple structure, convenient operation and good sealing. The rotary discharge valve is mainly composed of a valve body, a rotary valve disc, a drive device and a seal. When the drive device rotates the valve disc, the openings on the valve disc are connected to the outlet on the valve body in sequence, thereby controlling the flow of materials.

[0003] Existing discharge valves usually use a spiral feeding method for discharge, and the discharge speed and amount of the discharge cannot be accurately controlled, resulting in low discharge accuracy. In addition, general discharge valves cannot cut and filter the lumps of objects stuck together during the discharge process. Large lumps can easily cause blockage to the valve body, affecting subsequent use and increasing the number of maintenance times and maintenance costs. Utility Model Content
