Embodiment Construction

[0017] Specific terminology is used in the following description for convenience only and not for limitation. The words "inwardly", "inwardly" and "outwardly", "outwardly" refer to directions towards and away from, respectively, the designated midline or geometric center of the element being described, the specific meaning of which will be apparent from the context of the specification. Furthermore, as used herein, the words "connected" and "joined" are both intended to include a direct connection between two elements without any other elements, as well as an indirect connection between two elements with one or more other elements interposed therebetween. connect. Terminology includes the words specifically mentioned above, derivatives thereof, and words of similar importance.

[0018] Referring now to the drawings in detail, wherein like reference numerals are used to represent like elements throughout, in Figure 1 - Figure 1 1 shows a seal assembly 10 for a closure elemen...

Abstract

A seal assembly is for a closure element of a valve assembly including a valve body with a flow passage and an annular seat extending about the passage, the closure element being linearly displaceablealong a central axis and including a cylindrical body. The seal assembly includes an outer seal including an annular body formed of a polymeric material and having a centerline, an inner circumferential surface defining a seal bore, an outer circumferential surface, and opposing first and second axial ends, the first axial end having a generally radially-extending, annular sealing surface sealingly engageable with the valve seat. An inner connector includes a generally annular body formed of a substantially rigid material and disposed at least partially within the seal bore, the connector body having an inner circumferential surface frictionally engageable with the valve body outer surface to couple the seal with the closure element.

Description

technical field [0001] The present invention relates to seals and, more particularly, to seals for valve closure elements. Background technique [0002] Seals for valve closure elements such as those used in valve assemblies of linear pumps typically include an annular seal body formed from a polymeric material. In certain applications, polymeric seals are held to the metal element by snapping or pressing the seal around the metal closure element, which can fail due to separation of the seal from the closure element. In other applications, the seal is bonded or injection molded around the closure element, which can be expensive to manufacture or rework when the closure element is relatively large. Contents of the invention [0003] In one aspect, the invention is a sealing assembly for a closure element ( / closure element) of a valve assembly, said valve assembly comprising a valve body ( / valve body), said valve body There is a flow passage and a generally annular seat ex...
