Title: Super seal valve with mechanically retained seal

Abstract

This patent describes an improved valve assembly used in a well cementing tool in a well cementing operation or the like, the valve assembly comprising: an annular valve body housing retained within the cementing tool or the like, the annular valve body housing comprising: a valve seat portion having a bore therethrough; and a valve spring retainer portion secured to the valve seat portion and having a bore therethrough, the valve spring retainer portion comprising: an annular outer cylindrical member having a valve body guide retained therein by means of a plurality of supports extending from the outer cylindrical member to the valve body guide; and a valve body retained within the valve body housing, the valve body including; a valve body head adapted to engage a portion of the interior of the valve body housing, the valve body head comprising: a cylindrical member having a spherical end, frusto-conical outer surface and end surface having, in turn, a blind threaded bore therein; a valve body stem having one end secured to the valve body head, the valve body stem comprising: an elongated cylindrical member having a first threaded surface which releasably threadedly engages the blind threaded bore in the endmore » surface of the valve body head, a first cylindrical surface, a second threaded surface which is slidably received and retained within the valve spring retainer portion of the annular valve body housing; and an elastomeric valve seal retained on the valve body stem in constant, uninterrupted, abutting relationship with the valve body head and adapted to sealingly engage a portion of the interior of the valve body housing, the eleastomeric valve seal comprising.« less
