Abstract

PURPOSE: To prevent a pulverulent material from colliding against a casing and blade in a rotary valve conveying fixed quantity of the pulverulent material, by guiding a leak of air in an end side of the blade from a rotary directional front side partitioning chamber to its inside direction.
CONSTITUTION: A guide flow line 11 of leaked air is formed in a front side partitioning chamber 8 in the rotary direction of a blade 7. Said guide flow line 11 is formed by a gap between a baffle plate 12 and well surface 7A, and a leaked air stream 9, containing a pulverulent material 3 passing through a gap between internal peripheral surfaces and the blade, is decelerated by a baffle plate 12 and guided as a laminar flow to the internal direction of the partitioning chamber 8. Accordingly, movement of the pulverulent material 3 caused by a swirl is suppressed, and collision of the pulverulent material 3 against a casing 1 and the blade 7 due to intrusion of the leaked air can be avoided, then the wall surface can be prevented from wearing.
