Operating principle of the present invention is, flow control valve is not less than the lowest service force value of setting for the intake pressure controlling tap water water inlet pipe, normal water supply, flow control valve is in full-gear, tap water enters the current stabilization chamber buffering of steady flow compensation tank through flow control valve, again by the water outlet of current stabilization chamber through Water sterilizer to water pump two, and then give frequency-changing pressure stabilizing output water supply by water pump two relative to pressure detecting table two, flow detector on-line determination water outlet instantaneous delivery, the water storage cavity of steady flow compensation tank is by tube connector water storage simultaneously, electromagnetic valve one is opened, tap water enters water storage cavity, the negative pressure canceller being installed in water storage cavity is opened, and negative pressure canceller is automatically closed after water storage cavity storage full water, along with the arriving of water use peak phase, when tap water water inlet pipe pressure reduces, and when intake pressure being detected lower than the lowest service force value set by pressure detecting table one, flow control valve is by action immediately and turn down into water, fall with the decompression reducing tap water, reach current limliting, effect falls in pressure limiting, tap water water inlet pipe pressure is made to maintain more than the lowest service force value of setting, ensure that tap water water inlet pipe was in malleation water inlet state all the time before flow control valve, when tap water water inlet pipe pressure cannot be regulated by pass control valve for small flows lower than the lowest service force value of setting, flow control valve will cut out automatically, minor adjustment is closed at flow control valve, until in the process of final plant closure, the water storage cavity of steady flow compensation tank then passes through tube connector, differential pressure compensation pipe, water pump one and flap valve three-dimensional distribution pipe supplement the water-supply shortages of tap water water inlet pipe, water pump one starts, electromagnetic valve one cuts out, air will be opened and be filled into negative pressure canceller automatically with water storage cavity water level decreasing, to eliminate vacuum, treat tap water water inlet pipe pressure recover, and when output abundance and flow control valve standard-sized sheet, water pump one cuts out, electromagnetic valve one is opened, water storage cavity starts water storage again through tube connector and electromagnetic valve one, water storage cavity water level rises, when water storage cavity full water, negative pressure canceller is closed automatically, so repeatedly, complete the current limliting to tap water water inlet pipe, pressure limiting is fallen and current stabilization, water storage, the process that moisturizing ftercompction regulates, and water pump two is all in normal condition in the process,
In water pump two running, feed pipe passes through bypass pipe, rill buret to the air water energy-storing chamber water-filling of steady flow compensation tank to lay in regulating pondage, air in air water energy-storing chamber is compressed, along with decorporating of water use peak phase, water outlet instantaneous delivery reduces to low discharge water state thereupon, when detecting that water pump two conversion frequencies is lower than low discharge setpoint frequency, and when detecting that water outlet instantaneous delivery also continues 5s ~ 30s lower than setting small flow rate values by flow detector, system raising water pump two lift is made feed pipe pressure comparatively the normal constant pressure water supply of water pump two exceed 0.02 ~ 0.05MPa force value, and after voltage stabilizing 5s ~ 10s time, water pump two autostop and enter energy-conservation dormancy holding state, now compressed air is utilized to be supplied water to feed pipe by the regulating pondage force feed of deposit by the air water energy-storing chamber of steady flow compensation tank, to meet the demand of low discharge water, the continuous water supply of water pump two is stopped when realizing low discharge, reach energy-saving effect, along with the regulating pondage of air water energy-storing chamber reduces, the corresponding increase of compressed air volume, pressure reduces, when being detected feed pipe pressure by pressure detecting table two lower than the minimum operating pressure value set, water pump two wakes up automatically, and start water supply, so repeatedly, thus the efficient district of substantial deviation causes the not energy-conservation phenomenon with affecting application life at low discharge long-play to avoid water pump two.
Described air supply tank is used for the regularly quantitative air water energy-storing chamber to steady flow compensation tank and supplements air, because the air in air water energy-storing chamber directly contacts with water, lose there being the air of trace because of water-soluble, the long-time air water energy-storing chamber that will cause loses energy storage effect because air capacity reduces, therefore in order to ensure the operation condition of air water energy-storing chamber, need regularly in air water energy-storing chamber, to supplement air.Its tonifying Qi principle is: in air water energy-storing chamber, be equiped with level sensor be provided with high water level point and low water stage point two control points, when the water level in air water energy-storing chamber is positioned at high water level point, start tonifying Qi, now electromagnetic valve two cuts out, electromagnetic valve three is opened, water in air supply tank is discharged, outside air sucks air supply tank by respiratory siphon, treat 30s ~ 3min, until water in air supply tank is emptying and after being filled air, electromagnetic valve three cuts out, electromagnetic valve two is opened, and maintain 15 ~ 30s time, now air pressure in its tank supplements to air water energy-storing chamber by power conduit pressure by air supply tank, then electromagnetic valve two cuts out, the process of air supply tank draining air-breathing to tonifying Qi is opened and be restored to electromagnetic valve three, so repeatedly, until the water level in air water energy-storing chamber be in level sensor setting low water stage point and following time stop tonifying Qi, and recover normal, now, electromagnetic valve two keeps cutting out, electromagnetic valve three stays open state, if the water level of air water energy-storing chamber be again positioned at level sensor setting high water level point and above time, then start tonifying Qi again.
Described signal of water shortage transmitter is for the protection of water pump one and water pump two.When water pump one or water pump two work, because the water storage cavity of steady flow compensation tank causes its water level decreasing because of moisturizing, when detect the water level decreasing in water storage cavity to lower than signal of water shortage transmitter setting lack of water water level and following time, system judge lack of water and out of service in water pump one and water pump two and report to the police, electromagnetic valve one is opened, during when tap water water inlet pipe pressure recover and higher than lowest service force value 0.03 ~ more than the 0.10MPa set and flow control valve standard-sized sheet, water pump two will start and System recover normal water supply state automatically.
The invention has the beneficial effects as follows, the present invention is by the three-cavity structure of integrated for steady flow compensation tank current stabilization chamber, water storage cavity, air water energy-storing chamber, there is compact conformation, take up an area the advantages such as little, convenient for installation and maintenance, hygienic quality, and water storage cavity can carry out differential pressure compensation adjustment to tap water inflow deficiency, increase pondage, improve water supply security, air water energy-storing chamber can realize low discharge termination of pumping pressurize water supply and energy saving simultaneously, not only increase energy-conservation point, and extend application life.
