| Abstract: | The hydraulic performance of dashpot check valves determined experimentally shows that the coefficient of resistance of valves changes with valve opening and Reynolds number. Based on the curves, the interpolation formulas are obtained for forward and backward flow. They provide not only reliable parameters for analyzing transient problems concerning this type of valves but also the basis for finding appropriate curves for closing valves and improving design of valves. |
