ABSTRACT:
A pressure-responsive valve mechanism for discharging a slurry of reduced fluid content from the bottom of a solids-liquid separator. The valve mechanism includes (1) an inlet duct for receiving the slurry, (2) an outlet duct which extends below the inlet duct and which is free to move in an axial direction in response to an increase or a decrease in the downward force imparted to it by the slurry, (3) a constrictable nozzle attached to the lower terminus of the outlet duct, (4) a seal to provide a fluid-tight seal between the inlet duct and the outlet duct, and adapted to allow the outlet duct to move in an axial direction relative to the inlet duct, and (5) a lever mechanism mechanically actuated by the axial movement of the outlet duct to increase the constriction of the nozzle in response to an upward movement of the outlet duct and decrease the constriction of the nozzle in response to a downward movement of the outlet duct.
