ABSTRACT:
A device that regulates an outlet valve on a self-discharging centrifugal drum which diverts the closure fluid from a closure compartment that moves the piston valve from a closure position while the solids space is being partly or completely emptied, has, in addition to a supply line that supplies closure fluid to the closure compartment, an operating-fluid line in which a compressed air-controlled operating-fluid meter is positioned downstream of one shut-off and upstream of another shut-off. The meter consists of a housing divided by a tightly stretched and flexible diaphragm into two compartments, one that can be altered in capacity and that accepts operating fluid and a second that can be pressurized. This system ensures that a precise volume of operating fluid will be supplied to the outlet valve and determines the amount of solids to be removed.
