Abstract
A valve assembly includes a valve body, a bonnet coupled to the valve body, a valve stem, and an actuator coupled to the bonnet. The valve assembly further includes a damper system arranged within a body of the actuator. The damper system includes an inner sleeve, an outer sleeve, the outer sleeve being axially movable along the inner sleeve responsive to movement of the valve stem, and one or more ports extending through the inner sleeve, wherein movement of the outer sleeve drives a volume of air out of an interior formed between the inner sleeve and the outer sleeve through the one or more ports.
Claims18
A valve assembly, comprising:
- a valve body including a valve cavity and a flow bore extending perpendicular to the valve cavity;
- a bonnet coupled to the valve body;
- a valve stem extending along a valve stem axis through the valve cavity;
- an actuator coupled to the bonnet, the actuator including a connector coupled to the valve stem such that driving movement of the actuator is translated to the valve stem;
- and
- a damper system arranged within a body of the actuator, the damper system comprising:
- an inner sleeve, comprising;
- a stationary ring including one or more ports that extend through the inner sleeve;
- and
- a rotatable ring including one or more rotatable openings, wherein the rotatable ring is configured to rotate about a damper axis;
- and
- an outer sleeve, wherein the outer sleeve is axially movable along the inner sleeve responsive to movement of the valve stem;
- and
- wherein movement of the outer sleeve drives a volume of air out of an interior formed between the inner sleeve and the outer sleeve through the one or more ports.
A damper assembly, comprising:
- an outer sleeve including an opening;
- an inner sleeve positioned circumferentially within the outer sleeve, at least a portion of the outer sleeve overlapping the inner sleeve, and at least a portion of the inner sleeve being rotatable about an axis with respect to the outer sleeve;
- a base forming a portion of the inner sleeve, the base configured to couple the inner sleeve to an adapter ring;
- a resilient member arranged within an interior portion defined by the outer sleeve and the inner sleeve;
- and
- one or more ports extending through the inner sleeve, wherein a volume of air within the interior portion is configured to exit the interior portion through the one or more ports responsive to movement of the outer sleeve that decreases a size of the interior portion.
A valve assembly, comprising:
- a valve body including a valve cavity and a flow bore extending perpendicular to the valve cavity;
- a bonnet coupled to the valve body;
- a valve stem extending along a valve stem axis through the valve cavity;
- an actuator coupled to the bonnet, the actuator including a connector coupled to the valve stem such that driving movement of the actuator is translated to the valve stem;
- an adapter ring coupled to the bonnet and to a body of the actuator;
- a coupling location along the adapter ring;
- and
- a damper system coupled to the adapter ring at the coupling location and arranged within the body of the actuator, the damper system comprising:
- an inner sleeve;
- an outer sleeve, the outer sleeve being axially movable along the inner sleeve responsive to movement of the valve stem;
- and
- one or more ports extending through the inner sleeve, wherein movement of the outer sleeve drives a volume of air out of an interior formed between the inner sleeve and the outer sleeve through the one or more ports;
- wherein an opening is formed in the adapter ring, the opening being at a lower axial position than a surface of the adapter ring, and configured to receive an end of the outer sleeve when the damper system is in a collapsed configuration.
