FIELD: construction.
SUBSTANCE: group of inventions is related to water supply, namely to systems for water supply of building, structure, and also complex consumer of water supplies such as buildings, structures united into architectural-construction groups, micro-districts, quarters, settlements, towns. System for water supply of complex consumer, including local consumers in the form of separate buildings or structures, united, for instance into architectural-construction group, micro-district, quarter, settlement, town, represents hydraulic system, which comprises distributor network of pipelines communicated by working fluid - water with source of water supply in the form of water intake structure, or pure water reservoir, or artesian well, or directly to natural water basin via cleaning system, and with local consumers of water, pump equipment that includes at least one pump, mostly, with electric drive, comprising locking element, stop and/or stop and control valves, and also at least one hydromechanical device for smooth loading of hydraulic system, which is connected to pipeline, mostly at discharge side in section between pump that pulls head in pipeline or pump group and nearest stop and/or stop and control valves, which is communicated to pipeline by working fluid, mostly, by pumped working fluid, and installed with the possibility of automatic prolonged connection and disconnection of stop and/or stop and control valves, besides, hydromechanical device includes the following components serially connected to each other: inlet nozzle, having controller of opening speed of stop and/or stop and control valves and load transfer to hydraulic system, equipped with check valve and jet nozzle, and hydromechanical drive, comprising power chamber with body that contains at least one compartment with variable working volume, which is filled in controlled and returned manner by liquid working medium as pressure increases in pipeline, and transmission mechanism, besides, connection to hydromechanical device pipeline is arranged as double: at the inlet - by inlet nozzle it is communicated with pipeline by working medium, and at outlet - kinematically by hydromechanical drive with locking element of mentioned valves, besides, transmission mechanism is arranged as movable and joined with power chamber by "piston-stem" type or "membrane-stem", moreover, stem, in its turn, is movably connected to create drive with locking element of mentioned valves with the possibility of automatic displacements of locking elements in the range from complete closure to full opening for pipeline flow and back. Water supply system for building, structure is also described.
EFFECT: provision of smooth increase of load at hydraulic system of water supply, provision of smooth start-up of hydraulic system with exclusion of possibility for creation of high hydrodynamic loads at system, and also lower material intensity of start-up device elements, higher safety and reliability of system as a whole, lower costs for its maintenance and operation.
