Abstract
A seal including a metal annular body having an inner diameter and an outer diameter, the annular body including a main body portion including a first lip extending axially from the main body portion, the first lip adapted to provide a radial seal; and a second lip extending radially from the main body portion toward the outer diameter, the second lip adapted to provide an axial seal.
Claims19
A seal comprising:
- a metal annular body having an inner diameter and an outer diameter, the annular body comprising:
- a main body portion;
- a first lip extending axially from the main body portion, the first lip adapted to provide a radial seal;
- and
- a second lip extending radially from the main body portion toward the outer diameter, the second lip adapted to provide an axial seal,
- wherein the first lip is adapted to be deflected elastically and plastically in the radial direction, wherein the second lip has a shoulder with the main body portion, wherein the entirety of the first lip or the second lip has a substantially rectangular profile when taken in cross section along a central axis, wherein the first lip comprises a primarily axially oriented lip, and wherein the second lip comprises a primarily radially oriented lip that is radially overlapping with the main body portion such that it does not extending radially beyond an outermost diameter of the main body portion.

An assembly comprising:
- a valve having an axis, first and second bonnets, and a stem extending axially through the first and second bonnets;
- and
- a seal comprising:
- a metal annular body having an inner diameter and an outer diameter, the annular body comprising:
- a main body portion;
- a first lip extending axially from the main body portion, the first lip adapted to provide a radial seal;
- and a second lip extending radially from the main body portion toward the outer diameter, the second lip adapted to provide an axial seal, wherein the first lip is adapted to be deflected elastically and plastically in the radial direction, wherein the second lip has a shoulder with the main body portion, wherein the entirety of the first lip or the second lip has a substantially rectangular profile when taken in cross section along a central axis, wherein the first lip comprises a primarily axially oriented lip, and wherein the second lip comprises a primarily radially oriented lip that is radially overlapping with the main body portion such that it does not extending radially beyond an outermost diameter of the main body portion.

A method comprising:
- providing a valve having an axis, first and second bonnets, and a stem extending axially through the first and second bonnets;
- providing a seal comprising:
- a metal annular body having an inner diameter and an outer diameter, the annular body comprising:
- a main body portion;
- a first lip extending axially from the main body portion, the first lip adapted to provide a radial seal;
- and a second lip extending radially from the main body portion toward the outer diameter, the second lip adapted to provide an axial seal;
- and
- positioning the seal in contact with stem and at least one of the bonnets to seal at least one of the bonnet and the stem in both an axial and radial direction relative to the seal, wherein the first lip is adapted to be deflected elastically and plastically in the radial direction, wherein the second lip has a shoulder with the main body portion, wherein the entirety of the first lip or the second lip has a substantially rectangular profile when taken in cross section along a central axis, wherein the first lip comprises a primarily axially oriented lip, and wherein the second lip comprises a primarily radially oriented lip that is radially overlapping with the main body portion such that it does not extending radially beyond an outermost diameter of the main body portion.
