Abstract
A sealing ring is usable in a valve, and has an inner diameter defining a shape of the sealing ring. The shape may be configured to match the shape of a flow bore of the valve. A first side of the sealing ring is configured to abut a body wall of the valve. A profiled face is on a second side opposite the first side, and the profiled face is configured to match a closure member. An outer radial groove cutout is on an outer side between the first side and the second side, and an inner radial groove cutout is on an inner side between the first side and the second side. The outer radial groove cutout and the inner radial groove cutout are configured to elastically deform.
Claims5
A valve, comprising:
- a housing including a body wall, the housing comprising a flow bore, the flow bore for fluid flow in an axial direction;
- a sealing ring, comprising:
- an inner diameter configured to surround an opening of the flow bore;
- a first side configured to abut the body wall and comprising a cutout feature around at least a portion of a circumference of the sealing ring, wherein the cutout feature opens in the axial direction and forms a bounded space with the body wall of the valve;
- a profiled face on a second side opposite the first side;
- an outer radial groove cutout on an outer side between the first side and the second side;
- and
- an inner radial groove cutout on an inner side between the first side and the second side, wherein the outer radial groove cutout and the inner radial groove cutout are configured to elastically deform;
- and
- a closure member configured to close down on the sealing ring, wherein the profiled face is shaped to match the closure member.
