Abstract
The utility model provides a city water supply system for solving the technical problem that a subarea water supply system has the defect of low efficiency during a low peak period of the water consumption. The city water supply system is characterized in that: a check valve is arranged between each subarea water pump and a reservoir, and an external pipe network is accessed in a pipeline between the each subarea water pump and the check valve. The city water supply system of the utility model has the beneficial effects that: the external pipe network inherently has a certain pressure, thus by introducing the external pipe network with the certain pressure into a front end of the subarea water pump, the effect of energy saving can be achieved.
Description
Technical field
The utility model relates to a kind of water-supply systems.
Background technology
To the high-rise building water system, take the water rationing system at present, specifically be that the Gao Qu for this building, middle district and low district are provided with the subregion water pump respectively, promptly high district water pump, middle district water pump and low district water pump, they introduce the resident family in zone separately with the water in the reservoir.Its advantage is a water tank of having cancelled roof.Defective is that efficient is low when the water ebb.
Summary of the invention
For solving the problems of the technologies described above, the purpose of the utility model is to provide a kind of a kind of water-supply systems with energy-saving effect.
The purpose of the utility model is achieved in that between each subregion water pump and reservoir one way valve is set, it is characterized in that: on the pipeline between said each subregion water pump and the one way valve, insert outside ductwork (municipal tap water pipe network).
Compared with prior art, the beneficial effect of the utility model is: because the intrinsic certain pressure of outside ductwork, the outside ductwork that will have certain pressure is introduced the front end of subregion water pump, can reach energy-conservation effect.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is the sketch map of the utility model.
The specific embodiment
Said subregion water pump is high district water pump 41, middle district water pump 42 and low district water pump 43, between each subregion water pump and reservoir 1, one way valve 2 is set, and on the pipeline between each subregion water pump and the one way valve, inserts outside ductwork 3 through threeway.The utility model is established high district's water supply subsystem, middle district's water supply subsystem and low district's water supply subsystem like this, and each son supplies water son to regional water supply separately.The outside ductwork that will have certain pressure is introduced the front end of each subregion water pump, makes full use of the intrinsic pressure of outside ductwork, reaches energy-saving effect.
Claims (1)
1. water-supply systems are provided with one way valve between each subregion water pump and reservoir, it is characterized in that: on the pipeline between said each subregion water pump and the one way valve, insert outside ductwork.
