Abstract

A flow characterizing device (30) for a valve comprises: a body (31) in form of a disc with a centerline, the body (31) having an inner surface (33) corresponding to the outer surface of the valve member when the flow characterizing device (30) is installed in the flow path of the valve; and an outer surface (37), the inner and outer surfaces (33, 37) of the flow characterizing device (30) disposed in a spaced relationship along the centerline of the flow characterizing device (30). The body (31) of the flow characterizing device (30) further comprises a flow characterizing channel (49) therein extending between the inner surface (33) and the outer surface (37) of the flow characterizing device (30), thereby providing fluid communication between the inner and outer surfaces (33, 37) of the flow characterizing device (30), and defining an opening (32) in the inner surface (33) of the flow characterizing device (30). To achieve a tight sealing without sacrificing valve operability, the opening (32) of the flow characterizing channel (49) within the inner surface (33) of the flow characterizing device (30) is bordered by a first sealing lip (35), which projects from the inner surface (33) of the flow characterizing device (30) with a predetermined height and width.

A flow characterizing device (30), adapted for placement in a flow path (47) adjacent to a movable valve member (13, 42), for modifying fluid flow through the flow path (47), where the flow path (47) defines a longitudinal axis (46) thereof and the valve member (42) includes an outer surface (45) thereof having a controlling edge which is selectively movable, along a path extending transverse to the longitudinal axis (46), between a fully open and a fully closed position of the valve member (42) in the flow path (47), the flow characterizing device (30) comprising:

a body (31) in form of a disc with a centerline (48), the body (31) having an inner surface (33) corresponding in shape to the outer surface (45) of the valve member (13, 42);
and an outer surface (37), the inner and outer surfaces (33, 37) of the flow characterizing device (30) disposed in a spaced relationship along the centerline (48) of the flow characterizing device (30);
the body (31) of the flow characterizing device (30) further comprising a flow characterizing channel (49) therein extending between the inner surface (33) and the outer surface (37) of the flow characterizing device (30), thereby providing fluid communication between the inner and outer surfaces (33, 37) of the flow characterizing device (30), and defining an opening (32) in the inner surface (33) of the flow characterizing device (30), the opening (32) of the flow characterizing channel (49) within the inner surface (33) of the flow characterizing device (30) being bordered by a first sealing lip (35), which projects from the inner surface (33) of the flow characterizing device (30) with a predetermined height (h) and width (w),
wherein the first sealing lip (35) surrounds the opening (32) of the flow characterizing channel (49) at a predetermined distance (d5) from an edge of the opening (32).
