Controlling the Water Pressure in the Pressure Control Networks Using a New Automatic Pressure-Reducing Valve

Increase in urban water networks, network management is one of most important problem in which the parameters of the network pressure and leakage at night in search of networks and connections will be worn. Given that the urban water networks with more than 30 years old have been worn and is part of the network and still have not replaced the night of exhaustion and pressure leakage is due to increased consumption. Network Management in day and night in order to pressure, pressure-reducing valve was designed and built automated. In order to reduce demand hours (night) to minimize automatically pressure and increasing pressure on consumers can be provided for the maximum allowable pressure. The pressure-reducing valve on the network's performance is such that the input by a pilot pressure to a constant pressure at the output decreases. If the pressure is 6 bars pressure-reducing valve can be input by a pilot pressure to 3 times reduced and the pressure will be night and day, 3 times a night if not need this pressure will cause a leak. Pressure-reducing valve built in this research can be proposed to minimize the pressure in the night and day in different time with different pressure curve of the network will deliver.
