Abstract
A valve assembly for a liquid containing tank or the like, having a vortex breaker within the tank of liquid, and affixed to an external valve. The valve has a discharge port and a valve body with an outer member which allows the flow of liquid and a concentrically-spaced inner member provided with upper and lower seals to prevent the leakage of the liquid and allow uniform closure of the valve. The inner tubular member is movable vertically such as with a screw thread and associated handle, from a closed to an open position to allow flow of the liquid from the tank to a discharge port.
Claims26
In a valve assembly useful for removing liquid from a tank or container through a discharge port in the container comprising a vortex breaker adjacent to the discharge port, and a control valve for regulating the flow of liquid from the discharge port, the improvement which comprises a vortex breaker of upper and lower circular shaped legs parallel to each other to form a passage for the liquid between the legs, the lower leg having a concave shaped upper surface and being positioned in close proximity to the upper leg, the concave shape of the upper surface of the lower leg allowing passage of the liquid from the container between the legs into a conduit affixed to the lower leg, the upper leg having a convex upper and lower surface and having a smaller diameter than the lower leg.
A valve assembly for removing liquid in a uniform flow from a tank or container comprising:
- a container for liquid with a lower portion, a circular discharge opening in the lower portion, comprises a vortex breaker of upper and lower circular shaped legs parallel to each other to form a passage for the liquid between the legs, the lower leg having a concave shaped upper surface and being positioned in close proximity to the upper leg, the concave shape of the upper surface of the lower leg allowing passage of the liquid from the container between the legs into a conduit affixed to the lower leg, the upper leg having a convex upper and lower surface and having a smaller diameter than the lower leg a vertical conduit extending from said opening to allow flow of the liquid out of the container, a discharge port affixed to the vertical conduit at an angle extending downward, a shut off valve located within the conduit having a solid member moveable within the conduit, upper and lower seals on the solid member to prevent flow of the liquid between the conduit and the closure member, means for moving the solid member from a position of preventing the flow of liquid from the container to a second, lower position which allows flow of the liquid from the container to the discharge port.
