Embodiment Construction

[0010] Please refer to the figure, an IC card prepaid water meter, the water inlet 13 and the water outlet 12 of the water meter are respectively installed on the water pipe, the IC card 15 is inserted, the water metering controller reads the card, the indicator light 14 lights up, and the electric valve 16 is on Open under the control of the water metering controller, the water pipe is connected, the indicator light 14 is extinguished, and the IC card 15 is taken out to use water. When the remaining water volume is zero, the electric valve 16 is closed, and the indicator light 14 is lit. Under the control of the water metering controller, the motor 1 drives the screw 4 to rotate, and the screw 4 moves the valve core 5 through the thread. When the valve core 5 reaches the limit position, the water metering controller de-energizes the motor 1 to complete the opening and closing of the valve. Closed, the spool 5 has a through hole 7 that runs through the upper and lower ends of t...
