Abstract
The invention relates to a sampler mechanism for fluidly interconnecting a ball valve with the interior space of a septum closed container for the taking of closed loop samples of fluid materials. The sampler mechanism includes a needle assembly having a hollow needle and a needle seating collar which is positioned adjacent the ball in the ball valve, a threaded injector end fitting for attaching and securing the needle assembly to the ball valve, and an injector body for fluidly connecting the ball valve to the container and for providing a fluid passageway for fluid communication between the container and a side surface of the injector body.
Claims8
A mechanism for interconnecting a ball valve having a plurality of positions and an interior space of a sample container having a resealable septum closure, said mechanism comprising:
- an injector end fitting having a first end having an exteriorly threaded valve fitting surface and an interior forming a needle collar seating cavity, a second end, and a bore which communicates said second end with the needle collar seating cavity,
- a hollow needle having a sharp terminus and a mating end,
- a needle seating collar comprising a sleeve body having a flanged end and an orifice which is securely affixed about the mating end of said needle;
- an injector body having a first and second end, said injector body first end formed with an injector end fitting receiving cavity, said injector body having an orifice therein which communicates said injector end fitting receiving cavity to said injector body second end, said injector body having a first fluid passageway which communicates said injector body second end to a side surface of said injector body at a point intermediate between said injector body first and second ends, and a second fluid passageway which communicates said injector body second end to a side surface of said injector body at a point intermediate between said injector body first and second ends, at least one end of said first and second fluid passageway which terminates with the second end of said body being interiorly threaded.
