Description
Technical field
This utility model relates to a kind of high rise building water supply device, more specifically, it relates to a kind of high-rise pressure of supply water compensation device with hydraulic pressure bidirectional compensating function.
Background technology
Along with being on the increase of urban population, incity, city skyscraper is on the increase, increasing for the confession systematic research in skyscraper.Generally being called lower zone by 1 to 17 layer in high-rise, 18 to 35 layers are called middle layer region, and 36 layers start to be called high rise zone, when supplying water in centering high rise zone, it is generally required to secondary pressurized.
At present, relatively conventional is storage tank or cistern mode, tap water pipe network and user network are isolated, thus tap water pipe network will not be produced negative pressure impact during user is supplied water, but, the mode adopting water storage box needs to be separately provided water tank in building, do not only take up bigger construction area, and the restriction of the volume due to water storage box itself, need to open water pump frequently and water storage box is carried out moisturizing, further, this pressurization way of supplying water is due to the setting of water storage box, it is easy to cause the pollution of water；Also having a kind of relatively advanced secondary booster mode is multi-stage relay constant pressure water supply system; namely the partitioned mode in aforesaid three districts is utilized; single-stage constant pressure water supply equipment it is respectively mounted in the bottom in each district; then three complete equipment cascades are constituted; when the constant pressure water supply system of this multi-stage relay formula starts when hydropenia or maintenance and closes; need to carry out in strict accordance with the order of three grades, otherwise easily cause the disorderly closedown phenomenon of water pump.
nullFor solving the problems referred to above，The applying date is 2014.12.17、Application number is a kind of cistern free high rise building water supply method adopting water stream injection pump and water supply installation disclosed in the application for a patent for invention of 201410788744.4，Its main technical principle is the mode utilizing three grades of subregions，Variable frequency pump is utilized directly to supply water to 36 layers of high rise zone jet started，And from these partial high pressure current, individually draw one working fluid as lower zone and the ejector pump of middle layer region，It is kinetic energy by the pressure transition of the water under high pressure of this part，And the injection water causing water reservoir is sprayed to middle layer region and lower zone with the form of high pressure，It is bigger that the form of such secondary booster solves velocity fluctuation pump way of supplying water arranged side by side cost of equipment，And velocity fluctuation pump air relief valve way of supplying water reduces the pressure head in Zhong Di district by air relief valve，Water pump run the high problem of power cost.There is problems of in documents 1 once hydropenia occurs in water reservoir, namely during tap water pipe network water shortage, water pump there will be shutdown phenomenon, has had a strong impact on user network, causes user network hydraulic pressure unstable, causes inconvenience to the user.
And, documents 1 solves the pressure compensation that method is unidirectional form of the constant voltage problem of high rise building water supply, its towards be the discharge pressure to user one side, namely stable is output hydraulic pressure, but, once occur that the water yield of tap water supply net, hydraulic pressure are unstable or need lower than use, it all cannot be compensated by the method for documents 1, now there will be and occurs negative pressure appearance in tap water pipe network.
The applying date is 2014.12.22, application number be 201410801701.5 application for a patent for invention (hereinafter referred to as documents 2) disclosed in a kind of bicavate constant pressure water supply equipment, being characterized in that in water system increases a high pressure chest and a steady flow compensator, the wherein similar accumulator of the effect of high pressure chest, with in water low peak period, directly stop water pump, the earth pressure release of high pressure chest is out supplied water.The steady flow compensator arranged in documents 2 is possible to prevent in tap water pipe network negative pressure appearance occur, but, setting up of the hydraulic pressure of high pressure chest needs the booster pump being connected between steady flow compensator and high pressure chest to realize, but the startup of booster pump needs to be adjusted according to pressure of supply water opportunity, and the technical scheme in documents 2 fails to realize the automatic open close of booster pump.
