The invention relates to the field of water supply, namely, zoning systems of water supply networks.Known system sanirovanie water supply networks.with. USSR N 334345, E 03 B 1/02, Appl. 03.08.70, publ. 30.03.72). The system includes a pumping plant, inlet pipeline, the distribution unit. The system also includes a water distribution network, and a distribution device made in the form of regulatory capacity and tank installed between the conduits and regulatory capacity, and United with them by pipeline, on which are mounted a hydraulic Elevator. However, the system does not provide efficient use of water currents, leads to large energy losses and, in addition, the system is complicated and inconvenient in operation.Closest to the technical nature of the proposed and adopted for the prototype is a system of zoning of water supply networks and.with. USSR N 566908 (E 03 B 7/04, Appl. 19.08.75, publ. 30.07.77). The system includes a feed pump unit connected to the supply main pipeline system, zone water distribution network, distribution system, storage tanks for the band networks, and gain halirous capacity and equipped with Bolotnikova pereraspredelitsya flow zones and regulatory capacity. Switchgear is hydrocarbonoclastic distributing the flow of water over the area.However, this device is difficult to manufacture and unreliable in operation, due to the presence of the movable sealing compounds. In addition, the known system of zoning is not possible to effectively use the potential and kinetic energy of water flows, complex and unreliable.The basis of the invention the task is improving the system of zoning of water supply networks, in which the new implementation of the elements and relations between them allows the differentiation of the pressure at various points in the network, allowing more efficient use of water flow in the tanks and to simplify the system of zoning of water supply networks and to increase its reliability.The problem is solved in that in the system of zoning of water supply networks containing feed pump unit connected to the supply main pipeline, zone water distribution network, distribution system, storage tanks for the band networks, and storage tank of the Central zone is connected to the supply main pipeline, the bones, interconnected in the upper part, storage tanks the middle and lower zones connected by piping with valves equipped with actuators, to the bottom of one of the containers, the top of which there is an air valve, storage tank upper zone of the attached pipe with non-return valve to the bottom of the second tank, and storage tank of the Central zone connected by pipeline with the valve, provided with actuating mechanism to its upper part, while both tanks are equipped with level sensors, and actuators for valves installed with the possibility of them opening and closing while achieving appropriate levels of water. Each of the two vertical tanks switchgear can be performed (e.g., construction in mountainous terrain) from multiple, arranged one above the other tanks, the bottom of each upper pipe connected to the upper part of the lower capacity.A causal relationship between characteristics of the claimed device and achievable technical result is explained by the following.Concurrent distribution device is secure opening and closing them while achieving appropriate levels of water, as well as the implementation of links between elements of the system of zoning of water supply networks according to the claimed technical solution allows to divide the flow of water in streams with high and low pressure than in the original, to provide alternate partial filling of air and create excess pressure in one tank over another and to provide for the movement of water in storage tanks area networks. The result is the differentiation of the pressure at various points in the network that provides a more efficient use of water flows. In addition, the proposed solution eliminates the complicated and unreliable in operation - gertificate. Thus, greatly simplifying the system of zoning of water supply networks and increases its reliability.The invention is illustrated in the drawing, where Fig. 1 shows a system of zoning of water supply networks; Fig. 2 is a graph of the inclusion of valves.The zoning system of water supply network consists of a pump 1, the pipeline 2, the feed water storage tank 3 of the Central zone, accumulating tank 4 of the lower zone and the collection tank 5 of the upper zones of the s in the bottom of tank 5 of the upper zone, and through the valve 9 (actuator) capacity 7 is connected in the upper part with an accumulation tank 3 of the Central zone.

The tank 6 is connected through the valve 11 (actuator) with an accumulation tank 4 of the lower zone and through the valve 12 (actuator) with an accumulation tank 3 of the Central zone. The container 7 has a sensor 13 level, the tank 6 is supplied by the sensors 14, 15 water level.The system works as follows.Water by a pump 1 through the main pipe 2 enters the holding tank 3 of the Central zone. In phase 1, shown in Fig. 1, the valves 9, 10, 11 are closed, the valve 12 is opened. At the free surface of the water in the tank 6 is pressurized h more than on the free surface of the water tank 7. The air from the tank 6 is displaced into the container 7, the water from the tank 7 through the check valve 8 is supplied to the tank 5 of the upper zone, while the tank 6 is filled with water from the storage tank 3 of the Central zone. When the alignment of the water level in the tanks 6 and 7, the level sensor 14 sends a signal to the actuators of the valves 9, 10, 11, opens and closes the valve 12 (phase 2). Water from the tank 6 peremeshayet capacity 7. When the water reaches the level sensor 13 or 15, the valves are switched to the position in phase 1 and so onThe principle of the proposed device is tested at a pilot plant, which confirmed its efficiency.Thus, the claimed technical solution provides for the zoning of water supply networks, by differentiation of the pressure and ensuring the efficient use of water flow, as well as simplifying and improving system reliability.
