DIFFERENT SYSTEM ALL-IN WATER SUPPLY AND DISTRIBUTION SYSTEM

摘要

PURPOSE:To avoid shortage of water pressure on the malfunctioning system side by making water supply and distribution control to the water pressure and water quantity specification of the mulfunctioning system side when the water pressure and water quantity of the malfunctioning system is higher than that of a sound system, and reverse-supplying water from the malfunctioning system to the sound system. CONSTITUTION:In water supply and distribution pipes 4a, 4b, newly main pipe valves 8a, 8b are respectively provided on the downstream side from a branch point with a connecting pipe 4c, the water supply and distribution pipes 4a, 4b are connected by a return connecting pipe 4b on the downstream side of the main pipe valves 8a, 8b, and a connecting valve 7b is newly provided on the return connecting pipe 4b. A pump control device 9 is newly provided, and in the pump control device 9, pumps 2a, 2b can be controlled by preset water pressure of either of A system and B system. Thus, even if the preset water pressure of the malfunctioning system is higher than that of the sound system, the water pressures of both systems can be kept to the respective preset water pressures, so that there causes no shortage of water pressure in the malfunctioning system.
