Abstract

In water supply systems, One of the most important components as safety unit and the current controller (Switching flow and regulate the amount of flow) used in the arrangement of lines of water. In this study, according to multiple ponds in Tanguiyeh dam water pipeline to industrial and mining company Gol Gohar Sirjan Butterfly valve used in these ponds using Fluent software simulation has been the case. Flow characteristics such as speed, pressure and turmoil in the different modes of separation is studied. Current results show that Speed in opening and closing the valve will be rises. In the study of pressure was also observed that by closing valves pressure reduced in the gate valves.
