Abstract
A pre-payment water meter with IC card is disclosed that comprises core of the water meter, motorized valve, water metering controller. The motorized valve is the balanced motorized plug valve which consists of motor, motor holder, valve body, screw bolt and valve core, the motor holder is mounted on the valve body, the motor is connected with the valve core via the screw bolt, a through-hole which penetrates the upper end surface and the lower end surface is located on the valve core. The advantages of the invention are following: low initial power consumption, flexible and saving electricity, kinetic current free, accuracy of measuring, small inaccuracy, preventing user steal water.
Description
Technical field
The present invention relates to a kind of IC-card prepay water meter.
Background technology
The electronic appointment of commonly using is purchased the water automatic charging water meter, and its operation valve adopts solenoid valve, and this solenoid valve starts and is subjected to influence of hydraulic pressure big, if depressing the volume of opening the required electromagnet of this solenoid valve than big flood and the power consumption that starts moment is very big, and must working power.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, and a kind of IC-card prepay water meter is provided.
Technical scheme of the present invention is, a kind of IC-card prepay water meter, it comprises water meter watch core, motorized valve, water metering controller, it is characterized in that: motorized valve is the electronic stopcock of balanced type, form by motor, electric machine support, valve body, screw rod, spool, electric machine support is arranged on the valve body, and motor is connected with spool by screw rod, has on the spool to run through the spool through hole of both ends of the surface up and down.
Be respectively equipped with O-ring seal between described spool and valve body.
Flow sensor in the described water metering controller is made of tongue tube, magnetic sheet, gear and gear shaft, and magnetic sheet is arranged on gear shaft and the gear that tongue tube parallels.
The present invention has following advantage: it is little to start power consumption, and power saving does not flexibly need the power electricity, accurate measurement, and error is little, prevents that the user from stealing water.
Description of drawings
Fig. 1 is a structural drawing of the present invention.Fig. 2 is the motorized valve structural drawing.
Fig. 3 is the flow sensor structural drawing.
Embodiment
See also figure, a kind of IC-card prepay water meter, the water inlet 13 and the water delivering orifice 12 of water meter are installed on the conduit pipeline respectively, insert IC-card 15, water metering controller Card Reader, pilot lamp 14 is lighted, and motorized valve 16 is opened under the control of water metering controller, water pipe is connected, pilot lamp 14 extinguishes, and takes out IC-card 15 waters, when surplus water is zero, motorized valve 16 cuts out, pilot lamp 14 is lighted, and valve 16 is closed rear indicator light 14 and extinguished, under the control of water metering controller, motor 1 drives screw rod 4 rotations, screw rod 4 makes spool 5 motions by screw thread, and when spool 5 arrived spacing position, the water metering controller made motor 1 dead electricity, finish the open and close of valve, have on the spool 5 and run through the up and down through hole 7 of both ends of the surface of spool, 3 of spool 5 and valve bodies are respectively equipped with O-ring seal 6, and the magnetic sheet 8 of flow sensor is arranged on the gear 9 with pointer coaxial 10, reduce the influence of the magnetic force of magnetic sheet 8 and tongue tube 11 to the water meter degree, the power supply of water metering controller adopts main, pay powered battery.
