The position of outlet 5 is provided with rubber cup 29, and first guide cavity outlet pipe 28 internal volume is the 1.5-2 of rubber cup 29 cavity volume
Times.
Water meter operation principle and flow process:
As shown in Fig. 2-Fig. 3, current pass through water meter water inlet 2, water meter ante-chamber 3, drainage screen 6, mass-flow water inlet 7
Entering, promote antidrip spool 8 to move upward, current enter diversion cavity 12 by 6 big water conservancy diversion inclined holes 9, can be at water conservancy diversion
Produce rotating vortex in chamber 12, drive skirt-type impeller 13 to rotate.The two panels stainless steel substrates 14 that skirt-type impeller 13 top studs with,
Impeller often rotates one week, and stainless steel substrates 14 can be with metal detection sensor probe 15 two pulse signals of generation.Accordingly, single
Sheet machine can calculate impeller 13 revolution, and calculate water consumption and use water volume, skirt-type impeller middle spindle top to stud with hard conjunction
Gold globule, life-time service is the most easy to wear, and various indexs will not decline.
As shown in fig. 4-5, low discharge, the current of micrometeor can not promote the antidrip being enclosed in diversion cavity water inlet 7 top
Spool 8, can only flow to diversion cavity 12 by two weep inlet openings 10, little water conservancy diversion inclined holes 11, the jet propulsion of generation
Impeller 13 rotates, and can be substantially reduced initial-flow.
As Figure 6-Figure 7, supplementing rear single-chip microcomputer commander's battery 35 with money and power to reducing motor 17, motor output shaft 18 carries
Dynamic horizontal pole magnet ring 19 rotates 180 °, arrives stuck point.Motor output shaft 18 stops operating, and electric current increases suddenly, single-chip microcomputer
Commander's battery 35 power-off.Horizontal pole magnet ring 19 now magnetic pole replaces, and produces thrust with front Magnet 22, produces with rear Magnet 24
Suction, sliding axle 21 travels forward.Front needle-like spool 23 seals first guide cavity water inlet pipe 26, simultaneously after needle-like spool 25 will
First guide cavity apopore 27 is opened, owing to the hydraulic pressure of water meter back cavity 4 is higher than the hydraulic pressure of first guide cavity 20, pilot valve leather cup 29 to
Front motion, the water in first guide cavity 20 discharges from water meter outlet 5 through first guide cavity apopore 27, outlet pipe 28, valve opening.
The power conduction of this design is for contactless: reducing motor 17, motor output shaft 18, horizontal pole magnet ring 19 and first guide cavity
20 definitely isolate, and do not contact with water, can reduce fault rate.
Front Magnet 22 fixing on frame sliding axle 21 is contrary with rear Magnet 24 magnetic pole, can produce with horizontal pole magnet ring 19 simultaneously
Suction and thrust, can be multiplied and act on the power of frame sliding axle 21.And frame sliding axle 21 is when moving forward, front magnetic
Ferrum 22 reduces away from horizontal pole magnet ring 19, thrust.But rear Magnet 24 is near horizontal pole magnet ring 19, and suction strengthens, so frame
During sliding axle 21 moves left and right, produced power is consistent all the time.
Under pilot valve opening, water user closes valve stopping water, owing to diversion cavity 20 and water meter outlet 5 no pressure are poor,
Rubber cup 29 elastic reset is back to first guide cavity to close valve state, the water of water meter outlet 5 via first guide cavity outlet pipe 28
In 20.During water user's valve opening water, rubber cup 29 returns to valve opening state, and the water in first guide cavity 20 goes out from first guide cavity again
Water pipe 28 is discharged.Water meter in life-time service repeatedly with water, disable water, rubber cup 29 seesaws repeatedly.Water meter goes out
The water at the mouth of a river 5 is passed in and out first guide cavity 20 repeatedly by first guide cavity outlet pipe 28.Such as water quality inferiority, impurities in water is easily in first guide cavity 20
Precipitation fouling, causes first guide cavity inlet opening 26, first guide cavity apopore 27 to block, causes fault.Now by elder generation's guide cavity outlet pipe
28 have carried out extension design, 1.5-2 times that volume is rubber cup cavity volume in first guide cavity outlet pipe 28, make in pipe
The cubical content of water is more than the water yield by rubber cup extruding turnover guide chamber 20, and the water that can make first guide cavity 20 can only be guide
Circulation between chamber 20 and first guide cavity outlet pipe 28, reduces the first outer impurity of guide cavity 20 and enters first guide cavity 20, reduce fault rate.
The first guide cavity outlet pipe 28 that the bending lengthened is turned back also can extend the working time of rubber cup 29 when switch valve, reduces water
Vertical 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.After water meter
The water in chamber 4 enters first guide cavity 20 via inlet opening 26, and the hydraulic pressure of first guide cavity 20 is 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 filled
Value, recovers valve opening and supplies water after one minute, 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 dodges
Dynamic, display screen 37 shows water purchasing amout, successful recharging.Do not supplement with money such as rechargeable card or supplementing reception with money with non-dedicated rechargeable card
Rock above district, then flashing diode 39 does not flashes, and display screen 37 shows maloperation.
In reality, each flow section such as initial-flow, low discharge, conventional flow, big flow, maximum stream flow, impeller 13 with
There is obvious difference in the coefficient of flow.Directly gathering signal from impeller 13 owing to this table uses, single-chip microcomputer can be to each flow
Section coefficient 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 enters individual error respectively
Row is revised again, is greatly improved the measuring accuracy of water meter.In use, due to China's area water quality inferiority individually, make for a long time
Decline by the measuring accuracy easily making fouling, mechanical wear etc. in table cause, it is possible to on-the-spot off-balancesheet error correction.
Modification method: first design and produce+0.5% ,-0.5% two and revise card, be transferred to repair by display screen 37 by function key 38
Positive interface.If water meter measurement flow is less than actual flow, then the correction of use+0.5% is stuck in above sensing region of acceptance to shake and makes a movement,
The metered flow of 0.5% can be improved, then rolling makes a movement, and can increase again by the metered flow of 0.5%, until metered flow is with actual
Till flow is consistent.If metered flow is more than actual flow, the correction card of available-0.5%, with same method correction.Also can distinguish
Make high district, each flow section in low district+0.5% ,-0.5% many groups correction card, to the different error in dippings of each flow section respectively
Revising, this method can make this table have high measuring accuracy.
Described above is only the ultimate principle of the present invention, not imposes any restrictions the present invention, every enters it according to the present invention
Row equivalent variations and modification, all within the category of the art of this patent protection scheme.
