The energy saving water supply of the present invention is as follows without the running that negative pressure line is concrete:
Steady-flow tank 10 in this supply channel is directly connected with municipal tap water pipe network, tap water enters and is stored in steady-flow tank 10 from steady-flow tank import 6, and eliminate by vacuum suppresser 9 and suppress vacuum, to prevent from municipal tap water pipe network is produced negative pressure, between steady-flow tank import 6 and tap water export, it is provided with vacuum table 1 simultaneously, valve 2, filter 3, backflow preventer 4 and antifouling separative valves 5, so as the water quality safety of monitoring intake pressure machine water inlet better, steady-flow tank uviol lamp 101 it is provided with in steady-flow tank 10, steady-flow tank inwall is provided with light-catalyzed reaction film simultaneously, this light-catalyzed reaction film is under the irradiation of steady-flow tank uviol lamp 101, there is light-catalyzed reaction, tap water in steady-flow tank 10 can be carried out further disinfection process, export 12 at steady-flow tank and go out to be connected to cartridge filter 14, water outlet in steady-flow tank 10 is filtered bacteria removing, guarantee the water quality safety health of the water supply to user, current discharge pressure in steady-flow tank 10 is detected (pressure being equivalent to pipe network) by distance-transmission pressure gauge 15, the outlet pressure of force (forcing) pump group is detected by outlet pressure sensor 22, when ductwork pressure is enough, the pressure value recorded is delivered in switch board 20 by outlet pressure sensor 22, switch board 20 controls main pump 17 and assists little pump 19 to close, tap water is delivered in user pipe either directly through pipe network, when insufficient pressure, switch board 20 controls main pump 17 and pressurizes, supply the difference of pressure, as usual carry out to guarantee to supply water, when being in the water use peak phase, switch board 20 controls main pump 17 and assists little pump 19 to pressurize simultaneously, to guarantee to supply water normally, when output is less, switch board 20 can only control to assist little pump 19 to carry out pressurizeing to save the energy, steady-flow tank 10 is provided with liquid level controller 7 and can the water level of its inside water storage be detected, liquid level controller 7 is connected with switch board 20, when water consumption is more than output, water storage in steady-flow tank 10 can substitute for traditional water tank and supplements user and supply water use, now, the level value that liquid level controller 7 records slowly reduces, when the numeral that liquid level controller 7 records is lower than water storage lower limit, switch board 20 controls steady-flow tank 10 and stops supplying water with supplementary water storage, when output can meet water supply use, switch board 20 controls steady-flow tank 10 and starts working, moisture storage capacity therein slowly recovers normal, the water level that liquid level controller 7 records rises, in pressurization water system, it is provided with vacuum tank 21, when being possible to prevent low discharge at night, there is frequently rising the phenomenon of termination of pumping, when guaranteeing system low discharge water, keep pipe network constant pressure a period of time.Tap water supply is assigned in each user by user's pipe valve 23 after eventually passing through pressurization, for using water wisely, prevent water waste or pipeline generation drainage, water leakage alarm device 24 is installed between user's pipe valve 23 and final user, this water leakage alarm device 24 includes effusion meter 241, electromagnetic valve 242 and watch-dog 243, and described effusion meter 241 is connected with described watch-dog 243 respectively with electromagnetic valve 242. Water leakage alarm device 24 carrying out practically is: the situation of current is detected by effusion meter 241, and situation is passed in watch-dog 243, watch-dog 243 is analyzed judging, when being defined as running water, when namely there is water leakage situation, watch-dog 243 can carry out reporting to the police and connect electromagnetic valve 242 circuit pass valve and cut off the water, to arrive water-saving purpose.
The energy saving water supply of the present invention is without negative pressure line, compared to common cistern water supply equipment, save operating cost, and preventing the long-term water storage of water tank to cause water pollution, and floor space is little, initial investment economizes, install simple, power failure can maintain water supply, it can be ensured that the water safety of user, has reached the purpose of energy-saving and emission-reduction simultaneously; The energy saving water supply of the present invention, without negative pressure line, is provided with filter, backflow preventer and antifouling separative valves, cartridge filter, water leakage alarm device may insure that water safety further saves water resource simultaneously.
Above-described embodiment only for technology design and the feature of the present invention are described, its objective is to allow and is familiar with these those skilled in the art and will appreciate that present disclosure and implement according to this, can not limit the scope of the invention with this. All equivalents done by spirit of the invention or modification, all should be encompassed within protection scope of the present invention.
