Abstract

A plug system is provided. The plug system may comprise an adapter having an annular body oriented about an axis, a passage defined by the annular body, and a retention feature protruding radially from the annular body. The retention feature may be configured to obstruct the passage. A threaded surface may at least partially define an outer diameter of the annular body. A fuse plug may be configured for insertion into the passage, and the retention feature may be configured to at least partially retain the fuse plug.

First claim

What is claimed is:

1. An adapter, comprising:
an annular body oriented about an axis;
a passage through the annular body, the passage defined by:
an inner guide having a first conical geometry,
an inner wall comprising a cylindrical geometry and extending axially from the inner guide, and
a retention feature formed integrally with the inner wall and protruding radially from the inner wall, wherein the retention feature defines a terminus of the inner wall and obstructs the passage, wherein the retention feature defines a cylindrical opening and wherein a diameter of the cylindrical opening is smaller than a diameter of the inner wall; and

an outer guide disposed radially outward from the inner guide and having a second conical geometry.

2. The adapter of claim 1 , further comprising a threaded surface extending axially from the outer guide and at least partially defining an outer diameter of the annular body.

3. The adapter of claim 1 , wherein the annular body comprises a copper-zinc alloy.

4. The adapter of claim 1 , wherein the adapter is configured to retain a fuse plug within the passage.

5. A plug system, comprising:
an adapter, comprising:
an annular body oriented about an axis;
a passage defined by the annular body;
a retention feature protruding radially inward from the annular body, the retention feature defining a terminus of the passage and configured to obstruct the passage;
a threaded surface at least partially defining an outer diameter of the annular body; and

a fuse plug configured for insertion into the passage, wherein the retention feature is configured to at least partially retain the fuse plug within the passage and wherein the fuse plug comprises an annulus with a ring seal disposed about the annulus, the ring seal configured to sealably engage the annular body.

6. The plug system of claim 5 , wherein the annulus comprises aluminum.

7. The plug system of claim 6 , further comprising a fusible material disposed within the annulus.

8. The plug system of claim 6 , wherein the adapter comprises a copper-zinc alloy.

9. A plug system, comprising:
an adapter, comprising:
an annular body oriented about an axis;
a passage through the annular body, the passage defined by:
an inner guide having a first conical geometry,
an inner wall comprising a cylindrical geometry and extending axially from the inner guide, and
a retention feature protruding radially inward from the inner wall and defining a terminus of the inner wall;

an outer guide disposed radially outward from the inner guide and having a second conical geometry;
a threaded surface extending axially from the outer guide and at least partially defining an outer diameter of the annular body; and

a fuse plug configured to slideably engage the inner wall.

10. The plug system of claim 9 , further comprising a wrenching feature at least partially defining the outer diameter of the annular body.

11. The plug system of claim 9 , wherein the annular body comprises a copper-zinc alloy.

12. The plug system of claim 9 , wherein the retention feature defines a cylindrical opening.

13. The plug system of claim 12 , wherein a diameter of the cylindrical opening is smaller than a diameter of the inner wall.

14. The plug system of claim 9 , wherein the adapter is configured to retain the fuse plug within the passage.

15. The plug system of claim 9 , wherein the fuse plug comprises an annulus with a ring seal disposed about the annulus, the ring seal configured to sealably engage the inner wall.

16. The plug system of claim 15 , wherein the annulus of the fuse plug comprises aluminum.

17. The plug system of claim 16 , further comprising a fusible material disposed within the annulus.
