Abstract
The invention relates to a water supply technology in which a pressurized fluid needs to be pressurized after pressure selection by use of a pressure balancer selector in secondary water supply, namely a pressure selecting pressurizing water supply technology. In the city water supply process, the water pressure of a water supply network fluctuates frequently due to the change of the water consumption of users along the way, while the water outlet pressure of a regulating tank filled with water from the water supply network is relatively stable. When the network water supply is sufficient, municipal pressure water supply (4) is selected by a selector (6) due to that the water pressure of the municipal pressure water supply is greater than the water outlet pressure (5) of the regulating tank, and then the municipal pressure water supply (4) is pressurized to secondary water supply pressure (10) by a pressure pump (8); at this moment, the excess pressure of the municipal pressure water supply is utilized by a secondary pressurization system. However, when the network water supply is insufficient (or zero), the water outlet pressure (5) of the regulating tank is greater than the municipal water supply pressure and thus is selected by the selector (6), and then the water outlet pressure (5) is boosted into the secondary water supply pressure (10), and the water storage amount of a water tank (3) meets the regulation requirement of secondary water supply on water volume. The pressure balance selecting pressurizing water supply technology has the capacity of utilizing the excess water pressure of the water supply network and the capacity of water volume regulation required in technical regulations of secondary water supply.

At present, in urban water supply, due to the variation of the water supply network user water supply volume in city, cause the water yield water pressure fluctuations of public supply mains each point larger.Like this, on urban pipe network, carry out the water supply of secondary pressurized, it carrys out instantaneous the differing greatly of the water yield and secondary pressurized institute water requirement, for the continuity that keeps supplying water, need before force (forcing) pump, establish a regulating tank, pressure water enters and by force (forcing) pump, sucks pressurization again after regulating tank and supply water, thereby accomplishes not only to keep the continuity of secondary water-supply but also can prevent from water piping system internal cause to come the water yield to can not meet the water requirement of force (forcing) pump and the appearance that produces negative pressure.The safe operation that keeps capstan system.But the drawback of this regulating tank pressurization hydrotechny is exactly that water overbottom pressure when entering regulating tank is lost completely, can not be utilized by follow-up compression system, and before force (forcing) pump, pipe network water overbottom pressure is wasted!
Summary of the invention
How to keep the existing water yield regulating power of regulating tank second pressure water supply system, can make full use of again water supply network water overbottom pressure one time, the invention provides a pressure balance and select pressurization hydrotechny, the regulated quantity that can meet 10 to 20 daily water consumptioies that require in the secondary water-supply regulation of city, can make full use of again water supply network water overbottom pressure one time.To reduce the acting of follow-up force (forcing) pump.
The technical solution adopted for the present invention to solve the technical problems is: in traditional cistern water supply system, between water tank and force (forcing) pump, set up a pressure balance selector (abbreviation selector).The water inlet of regulating tank is still supplied with by municipal pressure feedwater, and control valve is established in import.Regulating tank water outlet and a pressure water supply all need, by after pressure balance selector " selection ", can enter follow-up pressurization water system.This selector is one to have the closed container of degassing function, inside establishes an outlet and two unidirectional imports.Selector outlet connects force (forcing) pump import, and its two unidirectional import connects respectively regulating tank water outlet and a pressure feedwater.The unidirectional import hydraulic pressure of selector of Bonding pressure feedwater is with city planting ductwork water supply pressure frequent fluctuation like this, and the unidirectional import hydraulic pressure of selector that another connects water tank water outlet was stablized because of constant maintenance of high water tank.In said system, due to the closed container that selector is unidirectional import, two inlet fluid of its connection only have the large person of pressure can enter in selector, export pressurized pump suck pressurization by selector, and the little person of pressure is blocked in the import of selector and does standby outward.Like this, in the secondary water-supply of normal city, municipal pressure waterline network hydraulic pressure is much larger than regulating tank water outlet hydraulic pressure, and the selected device " selection " of municipal pressure feedwater enters the pressurization of force (forcing) pump intake, and the pressurized pump of municipal water overbottom pressure makes full use of; And that the selected device of regulating tank water outlet is blocked in the import of selector is outer standby.When municipal pressure water not enough (or being zero) causes in selector hydraulic pressure to drop to being less than regulating tank water outlet hydraulic pressure, regulating tank water outlet is selected device " selection " and enters in selector, by selector, export pressurized pump and suck pressurization, the selected device of municipal press water is blocked in outside the import of selector.System enters regulating tank for water state, the regulating action of water tank is utilized, in view of municipal pressure water-feeding pressure, to be less than water tank water outlet hydraulic pressure probability less, for avoiding storing water in water tank to can not get for a long time displacement, go bad, at selector, connect on the water inlet pipe of municipal pressure feedwater and establish a sequencing valve, with entering of in good time controlled pressure water, the water storage of forced adjustment water tank is regularly replaced.
The invention has the beneficial effects as follows, system is utilized front selector distinctive " pressure balance selection " function composition of force (forcing) pump, water present situation based on municipal pressure water-feeding pressure frequent fluctuation, when municipal pressure feedwater is sufficient, utilize selector to carry out pressure examination to the regulating tank water outlet of access and the feedwater of municipal pressure, regulating tank water outlet because of its hydraulic pressure is little and municipal pressure water-feeding pressure be selected device be blocked in outer do standby, the selected device of municipal administration pressure feedwater is selected pressurization, and the pressurized pump of municipal pressure feedwater overbottom pressure makes full use of; And when the feedwater of municipal pressure inadequate (or being zero) feedwater of municipal administration pressure because of its hydraulic pressure, little and regulating tank water outlet hydraulic pressure are selected device and do outside being blocked in standby, the selected device of regulating tank water outlet is selected pressurization, system enters regulating tank pressurization for water state, and the regulating action of water tank is given full play to.Therefore the present invention its have by industry, stipulate desired water yield regulating power and make full use of pump before the dual-use function of waterline network residue hydraulic pressure.
