Abstract
In this study, testing equipment with which several kinds of valves can be tested was composed. Two kinds of tilting check valves and a swing check valve were tested to analyze their dynamic characteristics. The results of the experiment showed that the tilting check valves protected the pump but that the swing check valve could not protect the pump when the reverse flow rate was high. Also the dynamic equation of the tilting check valve was formulated and simulated using system characteristic constant t$\small{_{c}}$ and one method of predicting t$\small{_{c}}$ by comparing the results of the simulation with the results of the experiment was proposed.sed.
