Check valve stop assembly and method of retention

摘要

A check valve stop assembly (70) and method of retaining the check valve stop assembly in a check valve flow body (50) without external fixation means, wherein the check valve stop assembly (70) includes a threaded check valve stop insert (10) and a check valve stop housing (12) including a threaded interior sidewall that defines a void space therein. The check valve stop insert (10) is inserted within the void space of the check valve stop housing (12) by mating the threads (24) of the check valve stop insert (10) with those of the check valve stop housing (12). The check valve stop housing (12) further includes an opening (42) formed in the sidewall through which at least a portion of the check valve stop insert (10) is accessible. The check valve stop insert (10) that is accessible via the opening formed in the sidewall is either coupled to the check valve stop housing (12) or mechanically deformed to prevent removal of the check valve stop insert (10) from within the check valve stop housing (12).
