| Abstract: | In order to solve the problem form the water hammer damage caused by the long-distance pipeline and large water head of Daxigou Water Diversion Project in Urumchi， a reasonable water hammer prevention scheme is finally obtained through the comparison made among the performances of various prevention equipment in combination with the calculation of hydraulic transient and the comparative selection of the water hammer scheme. The result shows that the operation safety of the pipeline can be effectively ensured by arranging air valve， slow exhaust valve and air collector along the pipeline as well as the control of the closing time for the regulation and energy dissipation valve installed at the end of the pipeline. |
