The present invention has 5 kinds of duties:
1. sufficient normal water supply phase of the tap water pipe network water yield
When tap water pipe network 1 pressure is higher than when setting value, by Intelligent control cabinet 4, close variable frequency pump 3, when tap water pipe network 1 pressure is lower than setting value, by the force value of pressure sensor 9,11 monitorings, Intelligent control cabinet 4 is adjusted operation number of units and the running speed of variable frequency pump 3, guarantee that user's pipe network constant pressure supplies water, and saves electric energy.Meanwhile, water inlet motor operated valve 16 is opened, self-cleaning tank 10 moisturizings to 90%.
2. water use peak phase
At water use peak during the phase, when threshold value that tap water pipe network 1 water yield is set lower than direct connection spacer assembly 2, the water velocity of reducing spout 26 improves, produce eddy current negative pressure, now by water supplement port 25, from self-cleaning tank 10, absorb water, the water supplementary from self-cleaning tank 10 together mixes with the water of tap water pipe network 1, by the water side 27 of direct connection spacer assembly 2, sends into variable frequency pump 3 water sucking mouths, has guaranteed ductwork pressure.
3. water low peak period
When water low peak period low discharge or Night, variable frequency pump 3 increases speed of service adherence pressure to the upper pressure limit allowing, water is pressed into rapidly in pressure maintaining tank 7, and then variable frequency pump 3 is out of service, and now the pressure of user's pipe network is provided by pressure maintaining tank 7 completely.Along with user's water, pressure can progressively reduce, and when reaching low pressure limit, variable frequency pump 3 starts, and again toward pressurize, fills with 7 water fillings, and then variable frequency pump 3 is out of service, runs so forth.This upper pressure limit to the assurance of the pressure reduction maximum of lower limit effect and the energy-saving effect of low discharge.
4. the automatic cycle of water and self-cleaning in self-cleaning tank
When tap water pipe network 1 water yield is always sufficient, reducing spout 26 water flow velocities do not reach the eddy current of requirement, direct connection spacer assembly 2 can not be opened, the water of self-cleaning tank 10 can not add to user side, thereby cause the water of 10 li of self-cleaning tanks to become " stagnant water ", in order to guarantee water quality, in this case, automatically start force handoff water source function, open self-cleaning tank 10 water outlet motor operated valves 17, time period replacing at water use peak phase and low peak period or at night, force to use self-cleaning tank 10 water sources, guarantee supplementing of self-cleaning tank 10 fresh waters.
When reaching setting cycle and the water level of self-cleaning tank 10 cleanings, reach in limited time lower, self-cleaning tank 10 water inlet motor operated valves 16, water outlet motor operated valve 17, electronic blowoff valve 19 are closed, electronic flushing valve 18 is opened, start high-pressure flushing device, high pressure rotary shower nozzle 20 has three weep holes, utilizes the centrifugal action of high-pressure water jet and the impetus of reaction force, makes the rotation of water spray limit, shower nozzle limit, realization is sprayed without dead angle, cleans water tank sidewall; Whirlpool Flushing nozzle 21 is distributed in four angles of bottom half, and during flushing, sewage forms high speed whirlpool, drives bottom half deposit, opens electronic blowoff valve 19, effluent sewerage.Clean for the second time, clean self-cleaning tank 10 comprehensively, emptying after the state of supplementing water to 90% again.
5. tap water pipe network is cut off the water
When tap water pipe network 1 is cut off the water, the main suction side 24 of direct connection spacer assembly 2 is closed, and by water supplement port 25, from self-cleaning tank 10, supplies water completely.
In sum, the present invention realized with without the identical energy-saving effect of negative pressure equipment, reduce operating cost; Direct connection spacer assembly has guaranteed stable water supply with coordinating of self-cleaning tank, and enclosed self-cleaning tank has self-cleaning function simultaneously, can change the water in water tank by automatic cycle, prevents " stagnant water " phenomenon, assure feed water safety, and equipment is stable, reliability service.
With way of example, describe the present invention above, but the invention is not restricted to above-mentioned specific embodiment, all any changes of doing based on the present invention or modification all belong to the scope of protection of present invention.
