Specific embodiment
The scheme of the invention is it is gentle to introduce peak regulation water tank 1 on the basis of original secondary water supply hardware configuration
Tank 4 is pressed, while considering the automatic control that sequencing is added, makes full use of air pressure tank 4 to store the characteristic of pressure, water supply device is small
Flow supply water when, using 4 inner septum elastic shrinkage of air pressure tank, water energy is stored in air pressure tank, switch off the pump 8 operation, benefit
The high pressure conditions that water outlet pipe network is kept with the elastic diaphragm 15 and storage water of air pressure tank, reopen again after ductwork pressure decline
Water pump 8 is run, and to 4 water storage of air pressure tank, is circuited sequentially, to reach energy saving purpose.
Referring to Fig. 1, a kind of specific embodiment of stabilized voltage device of the invention, the confession between inlet and outlet
Set gradually the first valve 19 in water lines 12, inlet gage 5, peak regulation water tank 1, straight pipe non-return valve 16, the second valve 18,
Water flow meter 14 and third valve 20, it is in parallel between the water inlet of straight pipe non-return valve 16 and the water outlet of the second valve 18
One section of water supply pipe 12, sets gradually the 4th valve 7 on this section of water supply pipe 12, water pump 8, telescopic head 9, non-return valve 10, and
Air pressure tank is arranged on the water supply pipe 12 between water flow meter 14 and third valve 20 in five valves 17 and discharge pressure table 13
4, air pressure tank 4 is connected on water supply pipe 12 by solenoid valve.Inlet gage 5 on water supply pipe 12, discharge pressure table 13,
Water flow meter 14 and solenoid valve 11 are connected on PLC2, and the water pump 8 of water supply pipe 12 is connected to frequency converter 3, frequency converter 3
It is connected on PLC2, PLC2 and frequency converter 3 are arranged in electrical cabinet 6, the first valve 19 on water supply pipe 12, the second valve
18, third valve 20, the 4th valve 7 and the 5th valve 17 are all made of electronic valve, are respectively connected on PLC2.Frequency converter 3 is main
If adjusting the revolving speed of water pump 8, PLC2 acquires inlet gage 5, discharge pressure table 13 and water flow meter 14 and solenoid valve 11
Data, control frequency converter 3 and water pump 8 and run, and can control valve in water supply pipe, execute the preset program of user
Deng setting pressure is set in PLC2 as constants and stores, and when discharge pressure position sets pressure, water system of pressurizeing can
To meet the pressure requirements of user's water.
Stabilized voltage device of the invention is divided into three kinds of operational modes:
The first direct weighting water supply pattern: operation water pump is not needed then in the case where intake pressure is greater than setting pressure
8, it is directly that user supplies water by straight pipe non-return valve 16, is encountered in water supply pipe 12 when moving bigger with ripples, Ke Yikao
Consider and open solenoid valve 11, so that a small amount of water is flowed in or out air pressure tank 4, play the role of stable water supply water flow.
Second of constant pressure water supply mode: pressurization supply water water outlet water under normal circumstances, usual flow be greater than 10 cubic metres/
Hour, tap water enters the water supply pipe 12 of water supply device from water supply network, subsequently into peak regulation water tank 1, the water outlet of peak regulation water tank
By valve 7, water pump 8, telescopic head 9, non-return valve 10 directly can be used as the water outlet of water supply device and supply water for user, in this mode
Lower solenoid valve 11 is in close state, and air pressure tank 4 is not involved in work, and water pump 8 normally runs for frequency conversion state, uses water pressure table
13 numerical value are maintained at setting pressure.
The third pressure water supply scheme control: when supplying water in the case where small flow, usual flow is less than 10 cubes
M/h, PLC2 opens solenoid valve 11, converting operation water pump 8, and water supply is stored in air pressure tank 4 by the pressure run by water pump 8
In, stop the operation of water pump 8 when discharge pressure reaches 1.1 times of pressure of water entry pressure, using air pressure tank 4 inside it is elastic every
15 pressure of film guarantees that water supply device discharge pressure is constant, and as the time of water supply elapses, 4 internal pressure of air pressure tank drops to water supply
Low pressure limit is set, PLC2 detects that the flow number of water ga(u)ge 14 is still small flow, and system circulation uses pressure water supply
Otherwise mode closes and opens solenoid valve 11, make entirely to pressurize and supply water according to normal constant pressure water supply mode operation.
