Round resistance valve for wind powder adjusting valve

The utility model relates to the technical field of circular resistance valves for air and powder adjusting valves, in particular to a circular resistance valve for an air and powder adjusting valve. According to the technical scheme, the damping valve comprises a circular damping valve body, connecting ends are fixedly connected to the two ends of the circular damping valve body, extending pipes are arranged at one ends of the two connecting ends, and adjusting mechanisms used for horizontally adjusting the extending pipes are arranged at the connecting ends; the round damping valve has the advantages that the extending pipes can be conveniently and horizontally moved through the adjusting mechanisms, and the situation that the round damping valve body cannot be normally installed due to the fact that the distance between the two connecting pipelines is too large is avoided; and through the locking mechanism, the round damping valve body can be conveniently and rapidly disassembled and assembled, and the con
