Measures for reducing the probability of damages in water distribution networks

Summary

Measures for reducing the probability of damages in water distribution networks under certain technological operating conditions are considered. The experience of using a valve that prevents water surge in combination with a pressure relief valve is presented. Installing a valve that prevents water surge in the pressure manifold of pumping stations provides for the effective protection against damages of pressure water conduits in case of a sudden stop of pumps, as well as in case of a sharp uncontrolled pressure increase in them. Analyzing the operation of a multifunctional water surge protection valve with the remote control and function of maintaining the set pressure upstream proved a smoother pressure change at the outlet of the booster pumping station, as well as smaller deviations of the actual value from the set value as the volume of process water supplied changes. It is shown that the equipment is effective in the absence of variable speed control units, as well as in emergency situations.
