Abstract
A component for a ball valve that is configured to reduce noise. The component or “shoe” can install into the valve body, for example, on a downstream side of a throttling ball. In one implementation, the embodiments comprise an annular ring with an inner surface and an outer surface. The inner surface is cupped to receive a portion of the throttling ball. The outer surface may have a stepped profile with portions of the annular ring that have concentrically-decreasing diameter. This stepped profile sits in a corresponding recess in the valve body. Welds can be used to secure the shoe in place in lieu of fasteners, like bolts or screws.
Claims15
A valve, comprising:
- a valve body;
- a rotatable throttling ball disposed in the valve body;
- a first trunnion plate disposed on a first side of the rotatable throttling ball;
- a first shoe having an end to receive a first portion of the rotatable throttling ball, the first shoe comprising diametrically opposite cutouts, one of which receives a portion of the first trunnion plate;
- and
- a fastening element securing the shoe to the valve body.
A valve, comprising:
- a valve body;
- a rotatable ball disposed in the valve body;
- a trunnion plate;
- an annular ring with a cupped inner surface to receive at least a portion of the rotatable ball, the annular ring comprising diametrically opposite cutouts, one of which receives a portion of the trunnion plate;
- and
- a fastening element securing the annular ring to the valve body.
