Abstract
A check valve designed for incorporation in a milk line of large milking systems is comprised of a vertical tubular member having an outlet tube of smaller bore extending laterally therefrom at right angles thereto and a spherical valve element within the vertical member having a diameter considerably less than the bore of said member and greater than the bore of the outlet tube. The vertical tube extends above the discharge outlet a distance equal to the diameter of the valve element, is sealed at its upper end, and receives the valve element therein when milk is pumped through the lower end and out of the outlet tube. A horizontally extending circular valve seat is carried by the lower end portion of the vertical tubular member closely adjacent to the outlet tube and cooperates with the valve element to prevent return flow of milk from the outlet tube when pumping through the line ceases. The valve is more simple and less expensive to manufacture and eliminates the need for an elbow in the conventional milk line between the milk pump and cooler.
