Abstract

A self-centering valve adapter connection assembly includes a first equipment flange that is connected to a second equipment flange with an adapter ring. The adapter ring includes a first longitudinal flange with a tapered inner surface and a cylindrical outer surface. The adapter ring aids in centering the first and second equipment flanges while smoothing a fluid flow corridor between the first equipment flange and the second equipment flange.

First claim

The invention claimed is:

1. A valve adapter connection assembly comprising:
an adapter ring, the adapter ring including an annular ring having an inner surface and an outer surface, a first longitudinal flange extending away from the annular ring proximate the inner surface, and a second longitudinal flange extending away from the annular ring proximate the outer surface, the first longitudinal flange and the second longitudinal flange extending in opposite directions; and
a gasket that is configured to be disposed adjacent the annular ring,
wherein the first longitudinal flange includes an inner tapered surface and an outer cylindrical surface,
wherein the gasket is configured to be seated against the outer cylindrical surface of the first longitudinal flange, and
wherein the first longitudinal flange is longer than the second longitudinal flange.

2. The valve adapter connection assembly of claim 1 , wherein the inner tapered surface is tapered in the range of 5° to 45.

3. The valve adapter connection assembly of claim 1 , wherein the first longitudinal flange is thicker that the second longitudinal flange.

4. The valve adapter connection assembly of claim 1 , wherein the adapter ring is coated with a surface finish that reduces turbulent fluid flow.

5. The valve adapter connection assembly of claim 1 , wherein the outer cylindrical surface of the first longitudinal flange is adapted to be disposed adjacent to an inner cylindrical surface of an equipment flange.

6. An external internal self-centering valve comprising:
the valve adapter connection assembly of claim 1 .

7. The valve adapter connection assembly of claim 1 , wherein the gasket is configured to be disposed radially outward of the inner tapered surface.

8. A self-centering valve comprising:
a valve adapter connection assembly comprising:
an adapter ring, the adapter ring including an annular ring having an inner surface and an outer surface, and a first longitudinal flange extending away from the annular ring proximate the inner surface; and
a gasket that is configured to be disposed adjacent the annular ring at least partially between a first equipment flange and a second equipment flange,
wherein the first longitudinal flange includes an inner tapered surface and an outer cylindrical surface,
wherein the annular ring further has a first surface extending between the inner surface and the outer surface and a second surface extending between the inner surface and the outer surface opposite the first surface, and wherein the first surface is adapted to engage a portion of the second equipment flange and the gasket is configured to be disposed against the second surface, and
wherein the first longitudinal flange is adapted to directly engage an internal surface of the first equipment flange.

9. The self-centering valve of claim 8 , wherein the inner tapered surface is tapered in the range of 5° to 45°.

10. The self-centering valve of claim 8 , wherein the adapter ring is coated with a surface finish that reduces turbulent fluid flow.

11. The self-centering valve of claim 8 , wherein the outer cylindrical surface of the first longitudinal flange is adapted to directly engage the internal surface of the first equipment flange.

12. A valve adapter connection assembly comprising:
an adapter ring, the adapter ring including an annular ring having an inner surface and an outer surface, a first longitudinal flange extending away from the annular ring proximate the inner surface and terminating at a first end, and a second longitudinal flange extending away from the annular ring proximate the inner surface or the outer surface and terminating at a second end, the first longitudinal flange and the second longitudinal flange extending in opposite directions,
wherein the adapter ring is adapted to sealingly engage a first equipment flange and a second equipment flange at axial positions between the first end of the first longitudinal flange and the second end of the second longitudinal flange,
wherein the first longitudinal flange includes an inner tapered surface and an outer cylindrical surface and the second longitudinal flange includes an inner tapered surface and an outer cylindrical surface, and
wherein the outer cylindrical surface of the first longitudinal flange is adapted to directly engage the first equipment flange; and
a gasket configured to be seated against the outer cylindrical surface of the first longitudinal flange,
wherein the gasket extends radially outwardly of the second longitudinal flange.

13. The valve adapter connection assembly of claim 12 , wherein the inner tapered surface of the first longitudinal flange is tapered in the range of 5° to 45, and/or wherein the inner tapered surface of the second longitudinal flange is tapered in the range of 5° to 45°.

14. The valve adapter connection assembly of claim 12 , wherein the first longitudinal flange is longer than the second longitudinal flange.

15. The valve adapter connection assembly of claim 12 , wherein the first longitudinal flange is thicker that the second longitudinal flange.

16. The valve adapter connection assembly of claim 12 , wherein the adapter ring is coated with a surface finish that reduces turbulent fluid flow.

17. The valve adapter connection assembly of claim 12 , wherein the outer cylindrical surface of the first longitudinal flange is adapted to directly engage an inner cylindrical surface of the first equipment flange.

18. The valve adapter connection assembly of claim 12 , wherein the second longitudinal flange is adapted to directly engage the second equipment flange.

19. An external internal self-centering valve comprising:
a valve adapter connection assembly comprising:
an adapter ring, the adapter ring including an annular ring having an inner surface and an outer surface, a first longitudinal flange extending away from the annular ring proximate the inner surface and terminating at a first end, and a second longitudinal flange extending away from the annular ring proximate the inner surface or the outer surface and terminating at a second end, the first longitudinal flange and the second longitudinal flange extending in opposite directions,
wherein the adapter ring is adapted to sealingly engage a first equipment flange and a second equipment flange at axial positions between the first end of the first longitudinal flange and the second end of the second longitudinal flange,
wherein the first longitudinal flange includes an inner tapered surface and an outer cylindrical surface and the second longitudinal flange includes an inner tapered surface and an outer cylindrical surface, and
wherein the outer cylindrical surface of the first longitudinal flange is adapted to directly engage the first equipment flange.
