Operating principle of the present utility model is as follows:

1. during the water ebb, the flow Q that the tap water pipe network provides _FromGreater than user's water supply volume Q _WithThe time, the moisturizing in the retaining flow rate increment device of the remaining water yield is closed until the full float valve 11 of water, and this moment, the pressure of pump intake rose.During pressure that the intelligence control system of forming greater than single-chip microcomputer and PLC when this pressure sets; equipment can be shut down; water directly from first normally open solenoid valve 13, second normally open solenoid valve 9, second flap valve 4 to user's pipe network, thereby utilize original tap water pressure, energy-conservation greatly.It is for reducing main check valve 8 resistances that second normally open solenoid valve 9 is installed.During pressure that the intelligence control system of forming less than single-chip microcomputer and PLC when tap water pressure sets, intelligence control system can reach the effect of constant pressure water supply according to regulating the rotating speed of water pump and the platform number of input with the difference size of setting value.

2. during water use peak, the flow Q that the tap water pipe network provides _FromWater supply volume Q less than the user _WithThe time, intake pressure sensor 12 place's pressure are less than certain numerical value (but negative pressure can not occur) of setting, second normally open solenoid valve 9 cuts out, this moment, the B point pressure descended, under the pressure effect of water, water tank flap valve 7 is opened in the retaining flow rate increment device,

water pump

3,6 fetch water from the tap water path that retaining flow rate increment device and first normally open solenoid valve 13, main check valve 8 are formed respectively, play incremental effect.This moment, the pressure of water supply pipe water inlet was not negative value (vaccuum phenomenon can not occur) all the time.When negative pressure appears in the tap water pipe network, turn off first normally open solenoid valve 13, prevent that the generation of negative pressure and pipeline may be from float valve 11 and D air inlets and influence the operation of water pump.

3. no matter the water use peak or the output Q of water ebb tap water when the intelligence control system formed of single-chip microcomputer and the PLC pressure that detects intake pressure sensor 12 places keeps certain pressure continuously _FromAll the time greater than user's water supply volume Q _With, first normally open solenoid valve 13 cuts out, and

water pump

3,6 is directly fetched water from the retaining flow rate increment device.This is to prevent that water in the retaining flow rate increment device from not circulating when preventing that pressure in the water supply pipe is for a long time greater than certain value and contaminated rotten.

4. the liquid level sensor in the retaining flow rate increment device detects the liquid level in the water tank constantly, when liquid level arrives low water stage, for preventing the anhydrous idle running of water pump, equipment downtime protection water pump, anhydrous shutdown that Here it is.When liquid level arrived high water level, water pump can be started shooting.

5. if when having a power failure, equipment can make full use of the original pressure of tap water pipe network and supply water to the user, tap water directly supplies water to the user by first normally open solenoid valve 13, second normally open solenoid valve 9, second flap valve 4 after filling with the retaining flow rate increment device.

6. the intelligent observing and controlling system of being made up of PLC and single-chip microcomputer is monitored the electric current of water pump, voltage, running frequency at any time; the start-stop state, water level, ductwork pressure; each amount such as pipe network flow; and carry out record automatically, running status that can the Long-distance Control water pump, but disorderly closedown protection and reporting to the police; can carry out transfer of data by RS485 or public telephone network; communication robust is reliable, thereby realizes Long-distance Control, can realize centralized management by many cover system networkings.
