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.

First claim

What is claimed is:

1. 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.

2. The valve of claim 1 , further comprising:
a second trunnion plate disposed on a second side of the rotatable throttling ball.

3. The valve of claim 1 , further comprising:
a second trunnion plate disposed on an opposite side of the rotatable throttling ball.

4. The valve of claim 1 , further comprising:
a second shoe having an end to receive a second portion of the rotatable throttling ball, the second shoe resident on an opposite side of the rotatable throttling valve as the first shoe.

5. The valve of claim 1 , wherein the fastening element comprises adhesive.

6. The valve of claim 1 , wherein the fastening element comprises a weld.

7. The valve of claim 1 , wherein the fastening element comprises material that circumscribes the shoe.

8. The valve of claim 1 , wherein the fastening element comprises material that partly circumscribes the shoe.

9. The valve of claim 1 , wherein the rotatable throttling ball comprises multiple pieces.

10. The valve of claim 1 , wherein the rotatable throttling ball has through holes.

11. 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.

12. The valve of claim 11 , wherein the fastening element comprises adhesive.

13. The valve of claim 11 , wherein the fastening element comprises a weld.

14. The valve of claim 11 , wherein the fastening element comprises material that circumscribes the annular ring.

15. The valve of claim 11 , wherein the fastening element comprises material that partly circumscribes the annular ring.
