DISTRIBUTION HEAT SUPPLY NETWORK AND MAIN HEATING ROUTE-MAIN HEAT PIPELINE

摘要

FIELD: heating systems.;SUBSTANCE: group of inventions refers to heat supply engineering, and namely to distribution heat supply networks of buildings, facilities, as well as complex heat energy consumers in the form of buildings, facilities combined into architectural and construction groups, microdistrict, quarter, village and town, and to the main heating routes - main heat pipelines. Distribution heat supply network of complex heat energy consumer with local consumers in the form of separate buildings or facilities combined e.g. into groups of buildings and/or facilities, microdistricts, quarters, villages and towns, includes hydraulic system containing the following is switched as to heat carrier - namely of hot and/or return water with the above local heat energy consumers included in the complex consumer and with heat supply source e.g. boiler house, boiler room or the main heating route: distribution pipelines containing the locking element, shutoff and/or shutoff and control valves, pump equipment including at least one pump namely with electric drive, as well as at least one hydromechanical smooth load device of hydraulic system, which is connected to delivery pipeline namely on the delivery side in the section between the pump or pump group creating the head in the pipeline and the nearest shutoff and/or shutoff and control valves. That device is connected to the pipeline as to the working medium, and mainly as to heat carrier and installed with the possibility of automatic prolonged activation and deactivation of shutoff and/or shutoff and control valves. At that, hydromechanical device includes an inlet branch pipe and mechanical-hydraulic drive which are connected to each other in-series. Inlet branch pipe includes a housing, speed control of opening shutoff and/or shutoff and control valves and load transfer to hydraulic system, which is equipped with non-return valve and spraying nozzle. Mechanical-hydraulic drive includes power chamber with the housing containing at least one section with the changing working volume controlled with liquid working medium filled back thereto at pressure increase in the pipeline, and transfer mechanism. At that, mechanical-hydraulic drive is double connected to the pipeline: at the inlet it is connected with inlet branch pipe to the pipeline as to working medium, and at the outlet it is kinematically connected with mechanical-hydraulic drive to the locking element of the above valve; at that, transfer mechanism is movable and connected to the power chamber as "piston-stock" or "membrane-stock"; at that, the stock in its turn is connected in a movable manner thus forming the drive with the locking element of the above valves with the possibility of automatic movements of the locking element in the range from fully closed to fully opened position per the pipeline passage and vice versa. Heat supply and/or hot water supply system of the building, facility is described as well. The main heating route-main heat pipeline is described as well.;EFFECT: providing smooth increase of load on the hydraulic water supply system, providing smooth start-up of hydraulic system excluding the possibility of high hydrodynamic loads on the system, as well as decreasing material consumption of the start-up device elements, increasing the system safety and reliability as a whole, and reducing repair and operating costs.;25 cl, 11 dwg
