OFF-SET AND SINE-WAVE SHAPED BUTTERFLY PLATE TO REDUCE AERO-TORQUE AND REDUCE ACTUATOR SIZE

摘要

A butterfly valve plate has a base that includes an outlet facing surface, an inlet facing surface that is opposed to the outlet facing surface, and an axis of rotation about which the plate rotates. The inlet facing surface has an asymmetric sinusoidal configuration between a first end and a second end of the inlet facing surface. A sinusoidal length defines a distance between the first and second ends. The axis of rotation is disposed off a midpoint of the sinusoidal length. In addition, or alternatively, the axis of rotation is disposed off a centerline between the inlet facing surface and outlet facing surface.

1. A butterfly valve plate, comprising:
a base that includes:
an outlet facing surface;an inlet facing surface that is opposed to the outlet facing surface; andan axis of rotation about which the plate rotates; wherein the inlet facing surface has an asymmetric sinusoidal configuration between a first distal end and an opposite second distal end of the inlet facing surface; wherein a sinusoidal length defines a linear distance from the first distal end to the second distal end; wherein the axis of rotation is disposed off a midpoint of the linear distance.
