Among the figure: 1. valve 2. watch shells 3. water pipes 4. valve shafts 5. driven gears 6. are with the prominent seat of micro machine reductors 7. driving gears 8. switch magnet steel, 9. left tongue tube 10. right tongue tube 11. tongue tubes 12. micro processor 13.IC card interfaces 14. display screens 15. coefficient devices 16. connecting lines 17. sealing gaskets 18. sensor bodies 19. sealing nuts 20. coils 21. impellers 22. water pipes 23. executing agencies 24. power supplys, 25. gage probes, 26. data-storings, 27. bayonet sockets, 28. impeller shafts, 29. dops, 30. through wires holes, 31. battery door, 32. battery door magnet steel
With reference to the accompanying drawings, the utility model includes metering section, topworks (23), battery door (31), it is characterized in that metering section is communicated by connecting line (16) and coefficient device (15) by the gage probe (25) that is on the water pipe (3), the follower gear (5) of topworks (23) is installed on the valve shaft (4), be meshed with the driving gear (7) on the band micromotor reductor (6), battery door (31) is provided with battery door magnet steel (32).
Gage probe (25) has the impeller (21) that studs with magnet steel to be installed in the bottom of measurement sensory body (18) and to be installed in the coil (20) on measurement sensory body (18) top through sealing gasket (17) by impeller shaft (28), sealing nut (19) places in prominent seat of water pipe (22) and the water pipe (3) and constitutes, like this, impeller (21) just is in the current of water pipe (3), coil (20) then is in the top that isolates with current, coil (20) is connected with coefficient device (15) through through wires hole (30) by connecting line (16), that is to say that gage probe (25) communicates by connecting line (16) and coefficient device (15), is used to adjust measuring accuracy.When the water in the water pipe (3) flows, impacting impeller (21) rotates, wheel speed is directly proportional with discharge, magnet steel on the impeller (21) makes coil (20) produce pulse signal, signal is by amplification, shaping, be input to coefficient device (15), set coefficient, make it metering and reach design accuracy according to the relation of measured discharge and pulse signal.When measurement sensory body (18) is installed, make the bayonet socket (27) on dop (29) the aligning prominent seat of water pipe (22) on the measurement sensory body (18), add sealing gasket (17), and then sealing nut (19) is fastened on the prominent seat of water pipe (22).
Follower gear (5) is provided with switch magnet steel (8), corresponding with the left tongue tube (9) on the watch shell (2), right tongue tube (10), opening or closing of by-pass valve control (1), valve (1) moves according to the instruction of the open and close valve (1) that micro processor (12) sends, stop to the corresponding position of the switch, promptly drive valve (1) by driving gear (7), follower gear (5), left tongue tube (9), right tongue tube (10) and valve shaft (4) and constitute topworks (23) by band micromotor reductor (6).
The utility model principle of work: the micro processor in the master control board (12) is the core of monoblock table, and its gage probe (25), coefficient device (15), IC-card interface (13), data-storing (26), display screen (14), topworks (23) and power supply (24) all are communicated in micro processor (12).IC-card will be input in the micro processor (12) by the water yield that water supply department is bought by IC-card interface (13), and storage automatically, micro processor is according to purchasing water number according to topworks (23) is sent instruction, open water supply valve (1), when flowing, water obtains the water consumption signal by gage probe (25), through coefficient device (15) accurate data are input to micro processor (12) again, and the water data are handled by micro processor (12), when IC-card surplus water reaches the warning amount, water supply valve is closed automatically, reminds the user to purchase water, at this moment, the user inserts former IC-card again, can resume water supply.Micro processor when the water yield exhausts (12) provides the signal of valve-off (1), and valve (1) is closed automatically, this moment have only purchase water again after, IC-card is inserted IC-card interface (13) could recover normal water supply.Purchase water number amount and water situation and can go up demonstration at display screen (14), originally give the paying water meter and adopt table one blocking, micro processor (12) can feed back to user's water situation on the IC-card, the computing machine of water supply department is sold water system according to the IC-card feedack, but the unusual water situation of water system automatically prompting user reminds managerial personnel that abnormal user is checked.Originally the power supply (24) that gives the paying water meter adopts chargeable battery or dry cell, when power supply (24) when voltage is lower than setting value, micro processor (12) sends the instruction of valve-off (1), reminds the user to change battery or charging, supply voltage just resumes water supply after recovering normally automatically.
