Air volume control valve for pipe conveying goods - has nozzle plate in housing, with nozzle inserts, and lock washer

摘要

The air-volume valve for slowly conveying goods, especially in conjunction with a bucket wheel charging valve, has a nozzle plate (47) rotarily driven inside a housing (30), with different nozzle-inserts (50,51,66,67) which can be connected into the conveyor-pipe. A rotarily driven lock washer (40) is connected in front of the nozzle plate (47) in parallel series with it. A hole (43) or an insert (42) is connected in front of the nozzle insert (50,51,66,67). The nozzle plate (47) has a ball index for fine adjustment of the rotary position, with a ball (58) spring-supported on an index -disc (72) on index holes (59). ADVANTAGE - Separate nozzle inserts can be placed on the nozzle plate and connected according to the diameter of pipe, for the air volume to be regulated.
