Abstract: This paper introduced the structure and principle of energy-saving flap valve,analyzed and clarified the practical application and the effect of the flap valve in Ningxia large irrigation and drainage pumping station-Guhai Changshantou Pumping Station rebuild. The engineering practice shows that the energy-saving flap valve comparing with the traditional“Weir”water flow form,has the advantages of small running resist-ance,large opening angle,good flow pattern and small head loss. the application could save electric power energy,reduce the cost of operation and maintenance,make installation and maintenance convenient,improve the operation reliability of the pump station and the device efficiency and meet the requirements of national energy-saving policy.
