| Abstract: | With no unified experimental standards for the hydraulic control buffer butterfly valve,we tested the flow resistance of the valve by relying on the technology and instruments of universities and research institutes.According to the results and the analysis of the mechanism of pump and valve without electricity,we proved that the valve could be closed by preset angles and speed.It can control the water hammer efficiently and prevent accidents when the water pump turns round reversely and meet the need of an irrigation project of large flow,high head and long pipage. |
