The utility model is described in detail below in conjunction with the accompanying drawings：
It refer to Fig. 1-3, the present embodiment one, which provides, can flow the non-negative pressure unitized supply equipment of storage benefit, including laminate tank 100, very
It is empty suppressor 200, pump group 300, high-pressure pump 400, energy storage tank A500, energy storage tank B600, high-precision pressure regulating valve 700, electronic
Three-way valve 800, electrically operated valve 900, pressure transmitter 1000, electro connecting pressure gauge 1100, butterfly valve 1200, check-valves 1300.
Laminate the upper end of tank 100 and be provided with vacuum suppresser 200, upper end is additionally provided with pressure transmitter 1000, laminates the upper flanges of tank 100
Mouth connection municipal pipeline, laminates tank lower channel connection pump group 300, and city planting ductwork water flows to nothing after the boosting of pump group 300
Negative pressure water-supply installation outfall sewer 1400；
Further, pump group 300 is arranged in pairs or groups by metered flow is large, medium and small, according to flow signal, operation of automatically switching
Water pump, each flow section will have suitable water pump so that water pump, which is contributed, remains at high efficient district；
Further, electro connecting pressure gauge 1100 and pressure transmitter are provided with the outfall sewer 1400 of pump group 300
1000, outfall sewer 1400 includes branch's first via, the tunnel of branch second, the tunnel of branch the 3rd, branch's first via connection user's pipeline；
Further, the tunnel of branch second connects energy storage tank A500, this electric three passes valve by electric three passes valve 800
800 laminate tank 100 by the connection of high-precision pressure control valve 700；
Further, the tunnel of branch the 3rd is boosted by high-pressure pump 400, is connected after electrically operated valve 900, check-valves 1300 etc.
Meet energy storage tank B600；
Further, energy storage tank B600 connects energy storage tank by high-precision pressure regulating valve 700 and electrically operated valve 900
A500, pressure transmitter 1000 is provided with after energy storage tank B600, pressure transmitter 1000 is provided with before energy storage tank A500；
Further, energy storage tank A500, energy storage tank B600, high-pressure pump 400, high-precision pressure regulating valve 700, electric three passes
Valve 800, electrically operated valve 900 and other pipeline components collectively form Self Adaptive Control loop, can successfully manage different cities
Political affairs come water condition and complicated user's water condition.
Further, when municipal ductwork pressure is higher than direct-furnish service pressure (such as 0.20MPa), electric T-shaped valve 800 is led
Logical AB paths, energy storage tank A500 mainly plays pressurize Water storage, while can eliminate water hammer；Now water is mainly by laminating tank
100th, pump group 300, directly conveyed to user with water, meanwhile, high-pressure pump 400 is waited for an opportunity (according to energy storage tank B600 pressure values) and started,
Water storage is pressurized to energy storage tank B600, completes " energy " (pressure) " stream " (water) " storage " (savings) process；
