Abstract
A system for retrieving a fluid sample from a fluid source. The preferred embodiment of the present invention contemplates a system for insertion of a probe into a pressurized fluid stream by means of male threads which are threadly engaged in a female threaded housing. An elastomeric seal is employed to form a fluid barrier around a segment of the probe's outer surface.
Claims27
An insertion assembly comprising:
- a housing having a passage formed therethrough having first and second ends, said first end of said passage formed to fluidly engage a pressurized fluid source;
- a first retention nut having a probe shaft passage formed therethrough, said first retention nut having an outer diameter formed to threadingly engage said inner diameter of said housing passage in the vicinity of second end of said housing passage;
- a second retention nut having a probe shaft passage formed therethrough, said second retention nut having an outer diameter formed to threadingly engage the said inner diameter of said housing passage;
- a packing gland situated between said first and second retention nuts;
- a threaded shaft having first and second ends, an outer diameter, and a length having a fluid passage formed therethrough, said threaded shaft extending through said probe shaft passages of said first and second retention nuts and through said first and second ends of said housing passage, said threaded shaft forming a probe shaft;
- wherein said packing gland forms a fluid barrier about said outer diameter of said threaded shaft so as to prevent the escape of pressure from said pressurized fluid source.
