Description
Technical field
The present invention relates to public supply mains secondary system water supply field more particularly to a kind of combined type secondary water-supply water storages
The method of supplying water of equipment.
Background technique
The disinfection overwhelming majority of China's urban life drinking water (being commonly called as tap water) is using chlorination method at present.Chlorine disappears
The outstanding advantages of malicious method are that chlorine residue has lasting disinfection, and when chlorine residue is meant with chlorination, chlorination is contacted after a certain period of time,
Remaining chlorine dose in water.Passage of the residual chlorine concentration in public supply mains system at any time can gradually decay, and supply in city
Enough residual chlorine concentrations are kept in pipe network system it is ensured that the microorganism in tap water is controlled in acceptability limit.
Secondary water-supply refers to that when civilian be more than the public confession in cities and towns with requirement of the industrial building Drinking Water to hydraulic pressure, water
When water or self-built facility water supply network ability, user or personal way of supplying water are supplied through pipeline by the facilities such as storing, pressurizeing.
Secondary water-supply facility mainly includes water storage apparatus, pressurized equipment and pipeline three parts.Tap water secondary water-supply water storage apparatus (with
Lower abbreviation water storage apparatus) in can stay for some time, residual chlorine concentration may decay to very low water if the residence time is too long
It is flat, the effect for effectively killing microorganism in water is not had, causes the microbiological indicator of tap water in water storage apparatus exceeded.Therefore to the greatest extent
Residence time of the amount reduction tap water in water storage apparatus has great significance.
The mode that water storage apparatus is used has following three kinds.The first: water storage apparatus be mounted on skyscraper roof or
Intermediate floor, the tap water in public supply mains system are set by the water storage that the water in pump house is pumped to roof or intermediate floor
It is standby, then naturally flow in user family again；Second: water storage apparatus is mounted in pump house, in public supply mains system from
Water is flow to first in the water storage apparatus in pump house, is then sent in high-level user man by variable frequency pump direct weighting；Third
Kind: water storage apparatus, which is mounted at two, forms combined type water supply, is mounted in pump house at one, the roof of skyscraper is mounted at one
Or intermediate floor, the tap water in public supply mains system are flow to first in the water storage apparatus in pump house, then by pump house
Water be pumped to the water storage apparatus of roof or intermediate floor, then naturally flow in user family again.It is mounted on skyscraper roof
Or this water storage apparatus of intermediate floor is also known as high water tank, this water storage apparatus being mounted in pump house is also known as lower water box.
The third above-mentioned secondary water-supply mode, tap water are that the pressure of public supply mains system is leaned on to flow into lower water box,
It send by water pump to high water tank.For high water tank, according to standard GB/T 50015-2003 (version in 2009) " building water supply
Drainage Design specification " in the 3.8.3 articles of regulation: " when the domestic water system that building is adjusted using high water tank, water pump
Max water yield is no less than maximum hourly consumption ", it need to consider that its metered flow is greater than high water tank when selecting water pump
Maximum hourly consumption.For lower water box, it is generally the case that inflow can be greater than water consumption per hour per hour, but
The water use peak phase, at this moment the water reservation of lower water box was with regard to body then it is possible that inflow is less than water consumption per hour per hour
Reveal and.The high water tank of this secondary water-supply mode may only one, it is also possible to have multiple.This secondary water-supply mode,
Since tap water will stop in two water storage apparatus of height, it is easier to it is too long tap water residence time in water storage apparatus occur
The case where, it is exceeded so as to cause there is microbiological indicator, it is therefore desirable to while to tap water in two water storage apparatus of height
Residence time is controlled.
Water storage apparatus inlet flow rate refers to the flow of a certain moment tap water of water storage apparatus entrance, and for high water tank, it is big
It is small to be determined by water pump；It is determined for its size of lower water box by the pressure and water inlet pipe caliber of tap water in public supply mains system
It is fixed.Water storage apparatus rate of discharge refers to the flow of a certain moment tap water in water storage apparatus exit, for its size of high water tank by
The use regimen condition of the serviced user of high water tank determines；All high water tank imports supplied water for its size of lower water box by it
The sum of flow determines.Water storage apparatus retains the total volume that water refers to a certain moment tap water in water storage apparatus, and water storage apparatus retains
The number of water and the size of water storage apparatus rate of discharge determine residence time of the tap water in water storage apparatus.At present for
The control that water storage apparatus retains water is realized by the altitude valve in water storage apparatus, when the water in water storage apparatus
When position decrease beyond preset value, altitude valve is opened and water supply start, when water level rises to preset height, water level control
Valve closes and stops supplying water, and this control method absolutely not considers the problems of tap water residence time in water storage apparatus.
At present it has been proposed that adjust water pump according to the size of actual used water amount to the water supply of water storage apparatus, be specifically exactly with
The water supply for increasing water pump when water is big, the water supply of water pump is reduced in water consumption hour, and this method of supplying water mainly can solve
Guarantee to supply water when water consumption is big sufficient, the problem of water consumption hour minimization waste and water pump are lost.But this confession
Water method due to the quantitative relationship without specially considering water storage apparatus residence time that retains water and tap water in water storage apparatus,
Therefore water can not be retained come quantitative calculating according to the given residence time, also just can not quantifies calculating according to the given residence time
To the water supply of water storage apparatus, the result is that quantitative control can not be carried out to residence time of the tap water in water storage apparatus, here
The given residence time refer in order to guarantee tap water quality a period of time length given by man safely, when this period starts
The water that retains carved all flows out water storage apparatus after this period.So far, how tap water is stopped in water storage apparatus
Staying the time to carry out quantitative control is still the problem not solved.
In order to solve the above-mentioned technical problem, Chinese patent notification number is the prior art of CN105442670B at 2017 9
Disclose within 1st a kind of building water supply pipeline circulatory system and method for secondary water-supply water quality guarantee the moon, which includes building
Build water supply register one's residence pipe, promotion or water storage device, flow measurement or detection device, counter flow controller, building water supply standpipe, building family
