AI Technical Summary
When existing rotary valves are used for material conveying in sealed pipelines, the spacing between the feed plates cannot be flexibly adjusted according to different material densities, resulting in inconvenience in flow regulation.
A rotary valve with flow self-correction was designed. By setting multiple sets of positioning grooves and support rods on the positioning ring, the number and spacing of the feed pieces can be flexibly adjusted. Combined with the use of threaded pipes and fixed rings, the flow self-correction is achieved.
It enables automatic adjustment of the feed flow rate based on different material densities, improving the flexibility and efficiency of material conveying.
