Interior circulation, reduces the first outer impurity of guide cavity 20 and enters elder generation's guide cavity 20, reduce fault rate.The first guide cavity water outlet that the bending lengthened is turned back
Pipe 28 also can extend the working time of rubber cup 29 when switch valve, reduces water and hangs down phenomenon.
Rubber cup 29 transverse design, can reduce the manufacture difficulty of water meter case 1, and flow through the water of water meter outlet 5
Flow smooth and easy, reduce the pressure loss.
Such as Fig. 8-Fig. 9, when user is by when in water meter, the amount of money is finished, and single-chip microcomputer commander's battery 35 reversely supplies to reducing motor 17
Electricity.Sliding axle 21 rearward movement, pilot valve inlet opening 26 opens, and meanwhile, pilot valve apopore 27 is closed.The water of water meter back cavity 4
Enter first guide cavity 20 via inlet opening 26, the hydraulic pressure of first guide cavity 20 more than the hydraulic pressure of water meter outlet 5, leather cup 29 rearward movement,
Valve closing.When residue also remains 5m3During the equivalent amount of money, valve closing.Display screen 37 shows that speed is supplemented with money, recovers to open after one minute
Valve supply water, prompting water user's residue is few.
As shown in figure 11, protecting cover 33 is raised.Pressing function key 38, display screen 37 enters display state from resting state,
Display screen 37 goes out cash purchase water volume interface, gently shakes supplementing with money with punching the rechargeable card of volume above district.Flashing diode 39 flashes,
Display screen 37 shows water purchasing amout, successful recharging.Do not supplement with money such as rechargeable card or supplementing with money above reception area with non-dedicated rechargeable card
Rock, then flashing diode 39 does not flashes, and display screen 37 shows maloperation.
In reality, each flow section, impeller 13 and the stream such as initial-flow, low discharge, conventional flow, big flow, maximum stream flow
There is obvious difference in the coefficient of amount.Directly gathering signal from impeller 13 owing to this table uses, single-chip microcomputer can be to each flow section system
Number is modified respectively, and curve of error can be made to be modified to straight line.And available correction is stuck in off-balancesheet and carries out individual error more respectively
