Abstract:
A container system for pressurized fluids comprising:a pressure vessel comprising a plurality of hollow chambers formed from a polymeric material interconnected by polymeric conduit sections disposed between consecutive ones of said hollow chambers; a fluid transfer control valve attached to said pressure vessel and constructed and arranged to control flow of fluid with respect to an interior of said pressure vessel defined by the interiors of said hollow chambers and said conduit sections, said fluid transfer control valve comprising: a valve body having a threaded collar and a fluid chamber formed therein, at least a portion of said chamber being in fluid communication with the interior of said pressure vessel; a pressure relief mechanism coupled to said fluid chamber and constructed and arranged to permit fluid to flow out of said pressure vessel when the fluid within said pressure vessel exceeds a prescribed threshold level to thereby reduce pressure within said pressure vessel; and a projection extending from said valve body adjacent said threaded collar to be inserted into a conduit section of said pressure vessel, said projection having barbs formed thereon constructed and arranged to permit said projection to be inserted into the conduit section but to resist removal of said projection from the conduit section, said valve body having a fluid flow path extending from said chamber through said projection; and a ferrule for securing said conduit section onto said projection, said ferrule having a threaded opening at one longitudinal end thereof which is threadedly engaged with said threaded collar of said valve body to connect said ferrule to said valve body, said ferrule being arranged in an outwardly spaced coaxial relation with respect to said projection, said ferrule having a crimping portion constructed and arranged to be radially crimped onto a portion of the conduit section into which said projection is inserted to thereby compress the portion of the conduit section into said barbs and secure the conduit section onto said projection.
