バルブ。[Claims for Utility Model Registration] 1. A rotating body constructed by installing a plurality of rotor blades spaced apart in the circumferential direction of a rotating shaft between a pair of disc-shaped shroud blades located at both ends of the rotating shaft. is rotated in a cylindrical casing while maintaining a small gap on the inner surface of the cylinder, and the powder is conveyed from the powder supply port provided on the upper side of the cylindrical body of the casing to the powder discharge port provided on the lower side. In a sealed rotary valve, the rotor blade and the shroud blade are provided with an air chamber within the plate thickness that is brought into a negative pressure state by the intake air passing through the inside of the rotating shaft, and at the radially outer tip position of each of these blades, The above-mentioned air chamber has a shallow recess that is divided by the bottom plate partition wall and opens radially outward.
The closed rotary valve is characterized in that the partition wall is made up of a perforated plate with a hole diameter large enough to prevent the handling of powder from passing through. 2. The closed rotary valve according to claim 1, wherein the partition wall is a sintered metal element.
