Abstract
A valve assembly for a gas sampling apparatus. In one embodiment, the apparatus may comprise a valve body; a core valve, wherein a pin of the core valve the core valve is biased to a first, closed position; and a core valve carrier, wherein a body of the core valve carrier is biased to a first, closed position; wherein the pin of the core valve and the body of the core valve carrier may individually be displaced from their biased, first closed positions.
Claims20
A valve assembly for a gas sampling apparatus, comprising:
- a valve body;
- a core carrier, wherein the core carrier is biased toward a core carrier closed position;
- and
- a core valve comprising a core valve body and a core pin, wherein the core pin is biased toward a core pin closed position;
- wherein the core carrier and the core pin are individually displaced from their closed positions upon the valve assembly being seated in a chuck, thereby allowing a fluid to flow through the valve assembly.
A container assembly for collecting a fluid sample, comprising:
- a container body having a closed first end and an open second end;
- a cap comprising a cup shape and further comprising an aperture adapted to receive a valve assembly, the cap affixed to the open second end of the container body;
- a valve assembly secured within the aperture of the cap, the valve assembly comprising:
- a valve body;
- a core carrier, wherein the core carrier is biased toward a core carrier closed position;
- and
- a core valve comprising a core valve body and a core pin, wherein the core pin is biased toward a core pin closed position;
- wherein the core carrier and the core pin are individually displaced from their closed positions upon the valve assembly being seated in a chuck, thereby allowing a fluid to flow through the valve assembly;
- and
- a dip tube secured to a mating portion of the core carrier.
A method of collecting a fluid sample, comprising:
- providing a container assembly for collecting a fluid sample, the container assembly comprising:
- a container body having a closed first end and an open second end;
- a cap comprising a cup shape and further comprising an aperture adapted to receive a valve assembly, the cap affixed to the open second end of the container body;
- a valve assembly secured within the aperture of the cap, the valve assembly comprising:
- a valve body;
- a core carrier, wherein the core carrier is biased toward a core carrier closed position;
- and
- a core valve comprising a core valve body and a core pin, wherein the core pin is biased toward a core pin closed position;
- wherein the core carrier and the core pin are individually displaced from their closed positions upon the valve assembly being seated in a chuck, thereby allowing a fluid to flow through the valve assembly;
- and
- a dip tube secured to a mating portion of the core carrier;
- receiving the valve assembly in a chuck, the chuck comprising a chuck body formed to provide a valve seat and a mating projection, the chuck further comprising a chuck pin adapted to communicate with the core pin of the valve assembly;
- and
- seating the valve assembly in the chuck, thereby allowing fluid communication between an interior volume of the container assembly and one or more outlet or inlet bores of the chuck body.
