LOW HEAD LIQUID ENERGY CONVERSION DEVICE

摘要

A butterfly gate valve 16 diverts liquid flow alternately into and out of a pair of chambers 11, 12. By careful shaping and dimensioning of the components flow past the gate valve 16 merges smoothly with swirling flow within the chambers 11, 12 and hydrodynamic pressures assist the switching movement of the gate valve 16; the movement can even be fully flow actuated. The opposed rise and fall of liquid level in the chambers can be used to drive air through a turbine (21, Fig 2) and thus convert, for example, a water pressure head into electrical energy. IMAGE
