Realizing device of the present utility model comprises: air pressure tank 1, pressure pump 3, steady-flow tank 4, outfall sewer 5, butterfly valve 6, public base 9 and balance pipe 10.
Below in conjunction with drawings and Examples, further illustrate.
Embodiment 1: as shown in accompanying drawing 1,2,3, public base 9 rear portion, top fixed constant-current tanks 4, steady-flow tank 4 the place aheads connect respectively pressure pump 3 by least 2 pipelines of balance pipe 10, and further by butterfly valve 6, are all parallel-connected on outfall sewer 5 respectively, and air pressure tank 1 is installed on outfall sewer 5.
In aforementioned, butterfly valve 6 connects flap valve 8 through connecting hose 7.
In aforementioned, on steady-flow tank 4, there is water inlet 2.
In aforementioned, steady-flow tank 4 bottom one pipeline access balance pipes 10, by balance pipe 10, further pick out three and be connected with respectively the arm of electromagnetic valve 11 separately, the arm in two outsides connects respectively a rear access outfall sewer 5 of pressure pump 3, and the pipeline at middle part directly accesses outfall sewer 5.
In aforementioned, setting pressure table 12 on outfall sewer 5.
The utility model is applicable to all water supply systems that need to increase hydraulic pressure, constant flow rate.Condition of work is environment temperature: 5-40 ℃, during relative air humidity≤85%(20 ± 5 ℃), medium temperature: 4-70 ℃, supply voltage: 380V(+5% ,-10%).
In the utility model, hollow device is as the pressure in non negative pressure controller moment Monitoring and Controlling city planting ductwork and steady-flow tank 4, when tap water pressure is not enough, non negative pressure controller is started working, the hydraulic pressure that guarantees city planting ductwork is unaffected, not only guarantee the safety and stability of user's water, guaranteed the stable of municipal ductwork pressure simultaneously.
In the utility model, steady-flow tank 4 can continue water yield compensation to tap water pipe network automatically as two-way compensating device energy storage and release regulation device bidirectional compensating, can also to user's pipe network, play the effect of stabilizing compensation, guarantee that this equipment does not produce negative pressure to tap water pipe network.Water supply low peak period, bidirectional compensator is started working, guide the water under high pressure of pump outlet into high pressure chest and continue moisturizing, when liquid level rises gradually, nitrogen with pressure is extruded back in energy accumulating device, so just completed the process of low peak period to moisturizing in tank, when peak period water supply or municipal ductwork pressure decline, energy storing device releases energy, extruding high pressure chest water supplements to constant voltage chamber, municipal water with constant voltage chamber is together given user's moisturizing, has so just completed the process of peak period to user's moisturizing.
In the utility model, air pressure tank 1 is as the water-fast nitrogen of the built-in precompressed of energy storage device, when supply water in peak period, release energy extruding high pressure chest water to the moisturizing of constant voltage lumen net, make full use of the principle of law of conservation of energy, realize peak period to user's moisturizing, guarantee that the water in tank can farthest compensate in user's pipe network, suppress negative pressure and produce, guarantee city planting ductwork not to be exerted an influence.
In the utility model, non-negative pressure water-supply installation is realized equipment by Based Intelligent Control control technology and stabilizing compensation technology city planting ductwork is not produced to negative pressure, guarantees uninterruptedly to supply water to user's pipe network.The flow control valve that equipment adopts can automatically regulate city planting ductwork to the input water yield of equipment on the basis that maintains lowest service pressure, guarantee that city planting ductwork does not produce negative pressure, the nitrogen of water use peak certain pressure of energy storage device release preliminary filling during the phase, the water that guarantees stabilizing compensation tank high pressure chest compensates in constant voltage chamber with certain pressure, can supplement the deficiency that city planting ductwork carrys out the water yield within a certain period of time, pass through bidirectional compensator, at water low ebb, during the phase, stabilizing compensation tank is carried out to accumulation of energy, user pipe is played to stabilizing compensation effect, night and low discharge can supply water by small-sized expansion drum while supplying water, prevent water pump frequent starting.The pressure that takes full advantage of city planting ductwork, energy-saving effect is remarkable.If water pump is directly connected on city planting ductwork, do not need to build reservoir, directly to be connected the urban water supply regulations of rules of ，Dan China with city planting ductwork and in order preventing, surrounding resident water to be exerted an influence, life, production water pump mustn't be directly installed on city planting ductwork.In order to solve supply equipment, not only can be serially connected on municipal network water supply but also do not produce negative pressure, more do not affect other user's water, need between unit fixed on water pump suction and city planting ductwork, set up without vacuum flow amount controller, cavity-separating stabilizing compensation tank, bidirectional compensator etc., without vacuum flow amount controller, constantly monitor municipal ductwork pressure, guaranteeing also can to make full use of the original pressure of city planting ductwork when city planting ductwork does not produce negative pressure.
