CHECK VALVE CONTROL UNIT

摘要

Embodiments include a check valve that comprises a valve body defining an inlet port and an outlet port; a disc disposed within the valve body, wherein the disc is coupled to a pivot shaft and the pivot shaft is coupled to the valve body; a lever arm coupled to the disc, wherein when the disc rotates the lever arm rotates; an actuator shaft couple to a motor, and a first interference element coupled to the actuator shaft, wherein the lever arm contacts the first interference element when the disc is in a maximum open position; wherein when the motor rotates the actuator shaft moves longitudinally along its axis to move the first interference element thereby changing the maximum open position. Other embodiments are also included herein.
