AI Technical Summary
Conventional pressure reducing valves (PRVs) in water supply networks experience 'hunting' issues at low flow rates, leading to uncontrolled opening and closing, which can result in loss of supply and increased leakage due to over-pressurization.
A flow-controlled pressure reducing valve system (FCPRVS) is introduced, featuring a valve element connected to a substantially incompressible connector driven by a controllable motor. This system includes a flow meter, pressure sensors, and a controller that adjusts the valve position in real-time to maintain a desired pressure at critical locations, reducing pressure fluctuations and leakage.
The FCPRVS effectively reduces leakage and minimizes pressure fluctuations, ensuring a stable water supply by maintaining optimal pressure levels, even at low flow rates, thereby reducing fatigue failures and water consumption.
