Abstract
The present invention provides valve assembly for use in a floor drain. In various embodiments, the valve assembly comprises a substantially cylindrical seal frame, the seal frame defining a seal frame wall and at least one support wall extending in the longitudinal direction of the seal frame, a flexible sealing member located proximate a distal end of the seal frame, and an attachment tab configured to secure the flexible sealing member to the seal frame, wherein the seal frame and the support wall are further configured to create a resting deflection of the flexible sealing member, such that fluid may flow through the valve assembly in one direction, and the flow of gasses through the valve assembly is prevented in the opposite direction.
Claims19
A valve assembly for use in a floor drain, said valve assembly comprising:
- a substantially cylindrical seal frame, the seal frame defining a seal frame wall and a support wall extending in the longitudinal direction of the seal frame and located on a diametral plane contacting opposite sides of the seal frame wall;
- a flexible sealing member located proximate a distal end of the seal frame;
- and
- at least one securing feature extending from the support wall in the distal direction,
- wherein the flexible sealing member includes at least one hole corresponding to the at least one securing feature, wherein the at least one hole of the flexible sealing member is configured to receive the at least one securing feature, and wherein the seal frame wall and the support wall are further configured to create a resting deflection of the flexible sealing member, such that fluid may flow through the valve assembly in one direction, and the flow of gasses through the valve assembly is prevented in the opposite direction.
A valve assembly for use in a floor drain, said valve assembly comprising:
- a substantially cylindrical seal frame, the seal frame defining a seal frame wall;
- a flexible sealing member located proximate a distal end of the seal frame;
- at least one attachment tab configured to secure the flexible sealing member to the seal frame;
- and
- a pair of elongate positioning legs extending upwardly from opposite sides of the seal frame,
- wherein the seal frame wall is configured to create a resting deflection of the flexible sealing member, such that fluid may flow through the valve assembly in one direction, and the flow of gasses through the valve assembly is prevented in the opposite direction, and wherein each of the elongate positioning legs includes a turned end located on a proximal end thereof and configured to facilitate positioning of the valve assembly in the floor drain.
