DEVICE FOR DAMPING OF WATER HAMMERS IN PIPELINE Russian patent published in 2002 - IPC

FIELD: devices for damping of pressure fluctuations in pipelines in systems of water supply and amelioration systems. SUBSTANCE: device includes pumping plant, suction, discharge and bypassing pipelines. Device is distinguished by the fact that it is supplied with automatic flow switch which in case of stopping of one high-pressure pumps, directs return outflow of liquid not to pump, but to low-pressure line of main pipelines, where energy of said flow is fully damped and causes no damage to hydraulic system. EFFECT: higher operating reliability, simplified design and reduced labor input. 2 dwg
