Self-cleaning slurry metering valve |
摘要 |
A valve for metering a slurry includes a primary flow path for directing a continual flow of slurry through the valve, a valve stem which extends through the primary flow path and engages a passage in a valve seat for metering a portion of slurry passing through the primary flow path out through a second outlet in the valve. A portion of the valve stem which engages the valve seat passage is cut-away and when placed in communication with the primary flow path allows the flushing of accumulated solids through the valve seat passage to avoid persistent plugging of the valve.
