Description
Technical field
This utility model is related to supply equipment technical field, especially relates to a kind of multistage tank body of nfwg type pipe network pressure-superposed
Supply equipment.
Background technology
Traditional once supplying water is not well positioned to meet the water demand of modern city.With economic continuous development
And the continuous renewal of various technology, add on the basis of original water supply pipe network pressure-superposed non-negative pressure water-supply installation carry out secondary
Supply water.Due to non-negative pressure water-supply installation water supply and energy saving, save space, pollution-free good characteristic, it is able to by modern secondary water-supply
Industry is widely applied.
With the continuous expansion of urbanization process, skyscraper grows with each passing day, and has supplied water into a townie large focal spot.
Original municipal network pipeline once supplies water and is likely to be of reasonable effect for multi-storey building, but in high-rise and small sized multiple story building face
Front but seem unable to do what one wishes.Early stage carries out second pressure water supply by methods such as air pressure, frequency conversions to skyscraper and changes city
Water supply tension, this traditional secondary water-supply method, due to the formation in pond, the many intermediate members of water tank, is unfavorable for energy-conservation and right
Water resource easily causes secondary pollution.Technology make rapid progress, non-negative pressure water-supply installation is born therewith.Ten being developed so far at it
Many years, this new secondary water-supply mode of non-negative pressure method of water supply because its good save land, energy-conservation, pollution-free performance, quilt
Modern high-rise building water supplying system is widely applied.
Traditional feedwater pressure charging system that early stage adopts substantially has following two modes: is one, using " pond+water pump+height
The method of position water tank ", needs the water being pressurized first to fully enter tank, delivers to use after then being pressurizeed by constant speed pump in municipal water
Family, adjustment effect when elevated tank plays high ebb water.2nd, it is the method adopting " pond+frequency conversion speed adjusting pump ", set
After the pressure of supply water of water pump, under the control of converter, the rotating speed of water pump changes with the change of output, subtracts after reducing rotating speed
Little power, saves power consumption to a certain extent.
All there is following common fault in both way of supplying water, one is the water storage facility having opening, and water quality is easily subject to dirt
Dye, this secondary pollution directly affects water supply quality safety, sometimes even produces serious water pollution accident;Two is to be generally up to
Municipal water supply pressure to more than 20 meters of heads fails to be fully utilized, and causes larger energy waste.
No-negative-pressure water supply equipment does not set tank, directly absorbs water from city planting ductwork, during equipment work, by the control of equipment
Mode, steady flow compensator, the synergy of vacuum suppresser, eliminate the suction producing during pump working, to tap water pipe network
Dynamic pressure does not affect.The contact with air for the structure isolation of total enclosing, thoroughly avoids the secondary pollution of water quality, municipal water supply overbottom pressure
Stackable for lift utilization, water pump is to supplement to set water supply pressure and overbottom pressure insufficient section, and energy-saving effect is obvious.
Development pipe network pressure-superposed (no negative pressure) supply equipment with industry is improved with stability requirement to the safety of system,
The technology of common building secondary pressurized equipment cannot meet its demand, controls in Isobarically Control, Valve controlling, monitoring device
Need to be substantially improved etc. in intelligence degree.Operationally lack currently for pipe network pressure-superposed (no negative pressure) supply equipment and strive to property
Explosion stack guard technology, lead to pipe network service life is impacted, and easy booster cause the larger accident of ratio, and
Easily cause unsafe confession water environments such as pump group damage, valve damage, user's property loss.
Existing general anti-negative pressure technique adopts traditional vacuum suppresser, and frame for movement controls, in system failure no
Method finds in time, leads to pipe network negative pressure to produce risk larger.Due to system delay, instantaneous delivery increases or reduces and water outlet occurs
Ductwork pressure moment increases it is impossible to recover normal pressure in time, leads to city planting ductwork be caused damage, affects the pipe network life-span, increase
Big resistance of pipe system causes energy consumption to waste.The pressure compensation of water inlet does not have motive power, generally relies on compressed air and carries out ftercompction, effect
Really poor, negative pressure protective capability is limited, and when intake pressure fluctuates, easily outlet pressure is impacted.
Existing typically pipe network pressure-superposed (no negative pressure) supply equipment is all all-sealed structure, damages in pump group runtime or loses
During control, because not having the supplement of air pressure easily pipe network to be caused the negative pressure of subatmospheric power dangerous, lead to whole phase
The water supply closing pipe network impacts.
Chinese patent literature (day for announcing: on August 19th, 2015, notification number: cn 104846942a) discloses setting gas
Pressure tank energy-conservation pipe network Pressure-superposed water supply equipment is mainly made up of steady-flow tank, negative pressure canceller, water pump, switch board, air pressure tank, described gas
Pressure tank is mainly made up of tank body and air bag, is provided with sparge pipe and stretches in air bag water-filling to increase flowing and to avoid dead in air pressure tank
Water, air bag water outlet separately sets out the mouth of a river, makes to form interior circulation between the water inlet in air bag and water outlet, thus ensure that the water in air bag
Probability that is of fine quality good and eliminating hydrops in normal system, stagnant water.Described switch board be used for detect steady-flow tank intake pressure,
The discharge pressure of outfall sewer, controls the in good time action of negative pressure canceller and eliminates negative pressure, and control the automatic start-stop of water pump, change
Frequently, switching, working barrel increase and decrease and the switching of low discharge energy saver mode.
It is complete certainly that Chinese patent literature (day for announcing: on May 28th, 2008, notification number: cn101187215) discloses one kind
Dynamic current limiting type negative pressure-free pipe network Pressure-superposed water supply equipment, on pipe network, directly the pressurization of concatenation water pump is supplied water, thus cancelling pond, water tank
Deng water body expose store wait generation secondary pollution pilot process；Under totally-enclosed environment, eliminating negative pressure formation condition makes to set
Standby operation under constraints, does not produce negative pressure, it is to avoid the bad impact to pipe network during operating；Even if will produce negative
Pressure, the critical state producing in negative pressure also can eliminate it, prevents, the dual-use function that disappears ensures the stable smooth change of current state in pipe network
Change, make pipe network stable operation, each uses water spot by qualified tap water direct is supplied to user, have high energy-conservation, high reliability,
Strong applicability, Automatic Control, the outstanding feature of environmental protection.
