Abstract
A valve for a surf pool having a frame of generally horizontal and vertical members, a leg pivotally attached to the higher horizontal member, a foot at the end of the leg for opening and closing the valve and an actuator mounted on the lower horizontal member for pivoting the leg. The foot may include oblique surfaces for reducing its drag and for enhancing the seal between the foot and a valve throat in response to hydrostatic pressure on the foot.
Claims16
A surf pool gate valve for controlling the flow of water through a water carrying conduit from a water storage chamber of a surf pool which storage chamber when full with water provides a hydraulic head of at least ten feet, said valve comprising:
- a frame,
- a valve seat attached to the periphery of an end of a water carrying conduit,
- a foot for selectively controlling the flow through the conduit by seating against the valve seat,
- axially extending leg means fixedly connected to the foot for suspending the foot from the frame for pivoting movement about an axis,
- a peripheral seal connected to one of the foot and valve seat, said seal including first portions defining a first plane inclined with respect to the axis of the leg means when the foot is seated against the valve seat whereby the hydraulic head tends to compress the seal between the foot and valve seat,
- the seal having second portions defining a second plane disposed at an angle with respect to the first plane whereby abrasion of the seal upon movement of the foot is reduced, and
- actuating means for moving the leg means and foot against the hydraulic head between seated and open positions.
