Abstract
A seal is configured to reduce leak rates on a safety valve. These configurations may direct escaping material through a tortuous flow path that can significantly dissipate the amount of flow that exits the device. This tortuous flow path may include features, like undulations or loops, which can affect flow in a way that achieves these exit parameters for the flow.
Claims20
A safety valve, comprising:
- a pre-load unit that is configured to generate a load;
- a closure member under influence of the load;
- a seat in proximity to the closure member, wherein the closure member and the seat are configured to contact one another to form a seal in a closed position;
- and
- a leak capture unit disposed outside of the seal and comprising a flow path to receive flow of material that exits the seal.
2 more elements
A valve, comprising:
- a seat;
- a closure member moveable relative to the seat, the closure member having a position in contact with the seat that forms a contact interface;
- and
- a leak capture unit that circumscribes the contact interface, the leak capture unit comprising a flow path terminating at a first opening and a second opening on either end, respectively,
- wherein the flow path is configured to impede flow so that flow that enters at the first opening is less than flow that exits at the second opening.
2 more elements
A method, comprising:
- receiving flow into a pathway that is adjacent to a contact interface found between a closure member and a seat in a valve;
- and
- directing the flow in the pathway in a manner that impedes the flow so that the flow that enters the pathway is less than the flow the exits the pathway.
