Water control and diversion headgate and method of manufacture










Image Number 3 for United States Patent #5720575.

A water control and diversion headgate for use in irrigation systems, simplifying the headgate construction, easing its operation and improving its overall efficiency. This headgate includes a corrugated pipe, sometimes provided with an internal liner and having a beveled slot which extends slightly less than halfway through its diameter. A solid, flat elongated water-blocking gate, usually somewhat flexible, is positioned within the slot for vertical movement and for fully or partially blocking water flow through the pipe. The gate has a tapered lower edge and is adapted to make a sealing line contact with an adjacent pipe corrugation for sealing efficiency.
