초록

A flow noise restrictor for use with a valve. The flow noise restrictor reduces the flow area as the valve closes and forms vortices to reduce the noise such as due to the Bernoulli effect.

1. A flush valve comprising: valve body having an inlet and an outleta valve assembly comprising a valve member and barrel in communication with the inlet and the outlet and having an exterior surface and an interior surface with a valve seat defined at the upper portion of the barrel, the valve member seatable upon the valve seat to seal the inlet from the outlet;the valve assembly having a flow noise restrictor adjacent to the valve seat; andthe flow noise restrictor having a sidewall with a plurality of features formed in the sidewall and partially defining a fluid flow surface non-parallel with the valve member, the flow noise restrictor disposable about the exterior portion of the barrel and the fluid flow path extending from exterior of the flow noise restrictor, through the plurality of features to interior of the flow noise restrictor and into the barrel;wherein the flow noise restrictor has a continuously variable circumferential cross-section. 2. The flush valve of claim 1, wherein the flow noise restrictor is positioned such that vortices in fluid flowing through the flush valve are positioned upstream of the valve seat. 3. The flush valve of claim 1, wherein the sidewall is curved. 4. The flush valve of claim 1, wherein the flush valve assembly comprises a diaphragm assembly and the valve member comprising a diaphragm wherein the flow noise restrictor extends from the diaphragm. 5. The flush valve of claim 1, wherein the plurality of features are selected from the group consisting of sinusoidal, triangular, and semi-circular. 6. The flush valve of claim 1, wherein the flow noise restrictor comprises angled edges. 7. A valve assembly comprising: a valve member and a valve seat, the valve member seatable upon the valve seat to seal the inlet from the outlet; andthe valve assembly having a flow noise restrictor adjacent to the valve seat and partially defining a fluid flow path; andthe flow noise restrictor having a sidewall and a fluid flow surface defining a plurality of features;wherein the flow noise restrictor has a continuously variable circumferential cross-section; andfurther wherein the flow noise restrictor features extend from the valve member towards the valve seat and the fluid flow path passes between each of the features perpendicular to the features, the flow noise restrictor at least partially annularly disposed about an exterior circumference of the valve seat when the valve assembly is closed. 8. The valve assembly of claim 7, wherein the flow noise restrictor is positioned such that vortices in fluid flowing through the valve assembly are positioned upstream of the valve seat. 9. The valve assembly of claim 7, wherein the sidewall is curved. 10. The valve assembly of claim 7, wherein the plurality of features are selected from the group consisting of sinusoidal, triangular, or semi-circular. 11. The valve assembly of claim 7, wherein the plurality of features each have a width increasing towards the fluid flow surface. 12. The valve assembly of claim 7, wherein the flow noise restrictor comprises angled edges. 13. The valve assembly of claim 7, herein the flow noise restrictor features are non-symmetrically disposed about the flow noise restriction with respect to each other.
