Linearized controlled valves |
摘要 |
Servo control of a butterfly valve or the like, in which fluid flow is inherently non-linearly related to angular orientations of a vane or plug member, is effected through a function-generator mechanism interposed to render the system transfer function substantially constant. A function generator serving those purposes includes a mechanical cam-and-follower unit through which valve-controlling angular movements are maintained in a cosine-related slaving with angular movements of the rotor of an electrical servo motor.
