Abstract
A seal segment includes a flapper seal, a wire mesh acting as a hinge for the flapper seal, and a spring. The flapper seal has a first surface and a second surface. The wire mesh includes a first section connected to the first surface of the flapper seal and a second section connected to the first section. The spring includes a first end that is in contact with the first section of the wire mesh to apply pressure to the first surface of the flapper seal and a second end adjacent the second section of the wire mesh.
Claims23
A seal segment comprising:
- a flapper seal having a first surface and a second surface;
- a wire mesh acting as a hinge for the flapper seal, the wire mesh including:
- a first section connected to and extending across the first surface of the flapper seal;
- and
- a second section connected to the first section;
- a spring comprising:
- a first end positioned to apply pressure to the first surface of the flapper seal;
- and
- a second end adjacent the second section of the wire mesh;
- and
- a backing sheet positioned between the first section of the wire mesh and the first end of the spring;
- wherein the backing sheet is connected to and extends across a length and a width of the first section of the wire mesh so that the first section of the wire mesh is positioned between the flapper seal and the backing sheet.
