摘要： A fluid-sampling method and apparatus are disclosed. The apparatus includes a valve assembly, an overflow chamber assembly, a vacuum assembly and a sample bottle mounting assembly in particular arrangements. In certain preferred embodiments the overflow chamber assembly has an inner vessel, preferably a standpipe, within an outer vessel which forms an overflow chamber in which fluid from the standpipe can be viewed. The valve assembly preferably includes a sampling valve with an outer shell, an insert member and a pivotable valve member therein. The pivotable valve member preferably has a main body portion with first and second circumferential grooves therein and a diagonal bore therethrough for properly directing fluid from and through particular ports in the insert member based on the position of the valve member. The method includes drawing the fluid from the reactor vessel through a valve assembly into an inner vessel of an overflow chamber assembly, overflowing the fluid from the inner vessel into an outer vessel of the overflow chamber assembly, and thereafter retrieving a sample from the inner vessel.

摘要： The improved sampling valve assembly includes a diverting valve and an optional isolation valve in series for providing redundant shutoff. The assembly includes rounded-end, side-ported needles (as part of an easily-replaced needle assembly) to pierce the receptacle septum without "coring" and help prevent liquid "carryover." The assembly also has features providing metered, low pressure flow into the receptacle and very low dead volume. A receptacle guide has an interior cavity shaped like the receptacle to guide the inserted receptacle for aligned engagement of the septum with the needle assembly. The needle assembly is removable by removing only the keeper nut.

摘要： The improved valve assembly controls flow of fluid in "stream sampling" applications. The assembly valve block has at least two inlet passages, an outlet passage and a separate flow control valve for connecting each inlet passage to the outlet passage. Each valve has a single primary valving surface and each of the two inlet passages is selectively placed in flow communication with the outlet passage by positioning one of the primary valving surfaces. Actuation of each valve places the corresponding inlet passage in flow communication with an outlet passage common to all inlet passages. Both ends of the outlet passage are connected together by a "smooth bend" curvilinear tube attached to a fluid analyzer. The assembly can be operated by a control device for "programmed" stream sampling.
