Abstract
A tubular coupling comprising a first connector comprising a body defining a first passageway portion and a valve area, the valve area comprising a first volume adjacent to an end of the first passageway portion; and a second volume in fluid communication with the first volume; and a first valve disposed in the first volume of the valve area; and a second connector adapted to receive at least a portion of the first connector, the second connector comprising: a body defining a second passageway portion and a valve area, the valve area comprising: a first volume adjacent to an end of the second passageway portion; and a second volume in fluid communication with the first volume; and a second valve disposed in the first volume of the valve area.
Claims18
A tubular coupling comprising:
- a first connector comprising:
- a body defining a first passageway portion and a valve area, the valve area offset from a main centerline of the first passageway portion, wherein the first passageway portion is a static conduit within the body and wherein the valve area comprises:
- a first volume adjacent to an end of the first passageway portion;
- and
- a second volume in fluid communication with the first volume;
- and
- a first valve disposed in the first volume of the valve area;
- and
- a second connector adapted to receive at least a portion of the first connector, the second connector comprising:
- a body defining a second passageway portion and a valve area, the valve area offset from a main centerline of the second passageway portion, wherein the second passageway portion is a static conduit within the body and wherein the valve area comprises:
- a first volume adjacent to an end of the second passageway portion;
- and
- a second volume in fluid communication with the first volume;
- a seal at an end of the second passageway portion;
- and
- a second valve disposed in the first volume of the valve area;
- wherein the first and second valves are adapted to translate into the second volumes of the first and second connectors, wherein the second volumes of the first and second connectors are free of a spring, wherein the first and second valves are retained in the second volume after the first and second valves are translated into the second volume and wherein the first and second passageway portions are adapted to be in fluid communication when the first and second valves are disposed in the second volumes of the first and second connectors.
A connector comprising:
- a body defining a passageway portion and a valve area, the valve area offset from a main centerline of the passageway portion, wherein the passageway portion is a static conduit within the body and wherein the valve area comprises:
- a first volume adjacent to an end of the passageway portion;
- a second volume in fluid communication with the first volume;
- a seal at an end of the passageway portion;
- and
- a first valve disposed in the first volume of the valve area,
- wherein the first valve is adapted to translate into the second volume when the connector is coupled with a complimentary connector, wherein the second volume is free of any bias, wherein the first valve is retained in the second volume after the first valve is translated into the second volume and wherein the connectors are adapted to be in fluid communication when the first valve is disposed in the second volume of the connector.
A method of coupling tubulars comprising:
- providing a first connector coupled to a first tubular and a second connector coupled to a second tubular, wherein the first connector comprises a body defining a first passageway portion and a valve area, the valve area offset from a main centerline of the first passageway portion and the second connector comprises a body defining a second passageway portion and a valve area, the valve area offset from a main centerline of the second passageway portion, and a seal at an end of the second passageway portion, wherein the first passageway portion is a static conduit within the body of the first connector and the second passageway portion is a static conduit within the body of the second connector;
- translating the first and second connectors together until a first valve within the first connector moves from a first volume of the valve area of the first connector to a second volume of the valve area and a second valve within the second connector moves from a first volume of the valve area of the second connector to a second volume of the valve area, wherein the second volumes of the first and second connectors are free of a spring, wherein the first and second valves are retained in the second volume after the first and second valves are translated into the second volume;
- and
- initiating a fluid flow through the tubulars.
