Abstract
A valve operator is provided having a rotatable spindle extending along an axis. The rotatable spindle is rotatable about the axis. The rotatable spindle is additionally pivotable about a first pivot point. A pivotable linkage operably couples with the spindle. The pivotable linkage is pivotably movable about a second pivot point, such that rotation of the spindle moves the pivotable linkage in a pivoting motion about the second pivot point. Rotation of the spindle additionally pivotally moves the spindle about the first pivot point. The inventive valve operator has a fewer number of parts, a relatively low cost of manufacture, and a high operating efficiency relative to known valve operators.
Claims25
A valve operator, comprising:
- a rotatable spindle extending along an axis and rotatable thereabout, said spindle being pivotable about a first pivot point;
- and
- a pivotable linkage operably coupled with said spindle and pivotably movable about a second pivot point, such that rotation of said spindle pivotally moves said pivotable linkage about said second pivot point and pivotally moves said spindle about said first pivot point.
A system for actuating a valve, comprising:
- an automated valve actuator;
- and
- a valve operator, said valve operator comprising:
- a rotatable spindle having a first end, a second end, and a centerline axis extending therebetween, said first end being rotatably coupled to a bearing and said spindle being pivotable about a first pivot point at said bearing;
- and
- a pivotable linkage having a first end, a second end, and a second pivot point therebetween, such that said first end supports a rotatable threaded fixture that receives said rotatable spindle and said second end extends to communicate with a stem.
A valve operator, comprising:
- a rotatable spindle extending along an axis and rotatable thereabout, said spindle being pivotable about a first pivot point;
- and
- a pivotable linkage operably coupled with said spindle and pivotably movable about a second pivot point, such that rotation of said spindle pivotally moves said pivotable linkage about said second pivot point and pivotally moves said spindle about said first pivot point;
- wherein said rotatable spindle and said pivotable linkage are reversible, such that said resulting valve operator can be configured to push a stem in an upward direction or a downward direction, depending on the configuration.
