초록

A method for facilitating control of a butterfly valve, butterfly valves (40, 180) adapted for use with the method, and a fluid system (242) incorporating such valves are disclosed. All three use or incorporate butterfly valve structure that provides for relative translational movement (246) between the valve plate (42, 182, 248) and a pivot axis (232) in order to alter fluid dynamic torque exerted on the valve plate.

A method for facilitating control of a butterfly valve through which a fluid is being conveyed, wherein the valve comprises a valve plate which is rotationally positionable in a flow path to modulate flow of the fluid, and a pivot mechanism cooperating with the valve plate to define a pivot axis that geometrically divides a surface of the plate into two areas, the valve plate being pivotable about the axis so that the fluid exerts a net torque on the valve plate, the method comprising the step of: a controllably altering the net torque when the valve pla...
