Abstract
In accordance with the present invention, there is provided is a fluid control valve configured to attenuate acoustic resonance generated by a fluid flow. The fluid control valve includes a valve body defining a fluid passageway. A pair of seat rings are coupled to the valve body, with each seat ring defining an opening disposed about the fluid passageway. Each seat ring includes a plurality of vortex generators disposed about the radial periphery thereof for generating streamwise vorticies which suppress acoustic resonance.
Claims20
A valve including a valve body having a fluid passageway extending therethrough, and at least one seat ring which is positioned within the fluid passageway and comprises:
- an annular body including an inner annular face defining a seat ring opening, the annular body being cooperatively engaged to the valve body such that the seat ring opening is substantially aligned with the fluid passageway;
- and
- at least one vortex generator extending axially along the annular face only from an inlet end of the annular body and protruding radially inward from the annular face of the annular body into the seat ring opening, the at least one vortex generator being configured to induce a vortex within fluid flowing through the seat ring opening;
- a majority of the annular face at the inlet end of the annular body being uncovered by the at least one vortex generator and exposed to the seat ring opening.
In a valve including a valve body having a fluid passageway extending therethrough and a valve plate moveable between open and closed positions relative to the valve body to control fluid flow through the fluid passageway, the improvement comprising a seat ring which includes:
- an annular body including an inner annular face defining a seat ring opening which is aligned with the fluid passageway;
- and
- a plurality of vortex generators integrated into the annular face adjacent a first end of the annular body and protruding from the annular face of the annular body into the seat ring opening, the at least one vortex generator being configured to induce a vortex within fluid flowing through the seat ring opening;
- a majority of the annular face at the first end of the annular body being uncovered by the at least one vortex generator and exposed to the seat ring opening.
