The utility model is owing to combine IC-card and electric control gear, gearing and table body and water meter, water inlet is located at the bottom of table body, adopt the switching form of spiral lifting, cup leather packing and twice sealing of O-ring seal, make its switching steady, laborsaving, prolong power supply serviceable life, IC-card control controller drives gearing, makes its structure more reasonable, the requirement of complete realistic IC-card water meter has solved the difficult point of present this kind water meter.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As shown in the figure: the utility model be by it be by the table body 1, watchcase 6, counting assembly, gearing, IC-card 5, electric controller is formed, electric controller comprises power supply 21, motor 22, wiring board, display 24, its wiring board is connected with the IC-card chip, IC-card 5 and electric controller are contained in the table body 1 upper end watchcase, counting assembly is installed in the bottom of table body 1, its counting assembly is to be linked on the gear reducer 42 by gear shaft by impeller 31, sensor 43 is installed on the gear reducer 42, be characterized in: water inlet 11 is located at the bottom of table body 1, when closing water meter, hydraulic pressure on the pipeline makes its sealing property better greater than the pressure that goes out in the water jacket; Gearing is made up of gear set 31 and rotary valve screw mandrel 32 and the spin nut 33 that ends that is installed on the valve screw mandrel 32, end being equipped with on the spin nut 33 and only revolve post 34, end the valve rod 36 that a band boss is fixed in spin nut 33 bottoms, seating cup 35 is installed on the valve rod 36, the O-ring seal 38 that is slidingly matched is installed in the lower end again, O-ring seal 38 cooperates with water inlet, and gear set 31 is driven by the motor 22 of electric controller.
Pressure reduction when opening and closing in order to alleviate water meter has aperture on the O-ring seal 38, in order to increase the intensity of O-ring seal 38, embedded with metal sheet 37 in O-ring seal.
Display 24 adopts LCD, and its table covers 25 and adopts material transparent, and table covers 7 and is fixed on the watchcase 6 of water meter.
