| titleOfInvention | Hydro-surge bowl valve |
| abstract | A gravity-operated anti-surge valve for a turbine pump consists of a poppet adapted to be moveable under fluid pressure between a closed position and a valve seat for the poppet. The weight of the poppet biases the poppet in the closed position against the valve seat in the absence of fluid pressure. Fluid pressure developed by the pump forces the poppet open. As fluid pressure decreases when the pump is shut off, the weight of the poppet allows the poppet to gradually close against continuing fluid flow, preventing water hammer. As fluid pressure approaches zero, the poppet completely closes, preventing the weight of a column of water from rushing down the lineshaft at high speed and driving the pump impellers in reverse. The valve is located above the top bowl of the pump. |
