Embodiment
As shown in Figure 1, a kind of water meter structure that the utility model provides, comprise watchcase 1, top movement 2, bottom movement 3, be arranged at the water strainer 4 of watchcase 1 inside, on watchcase 1, be provided with water inlet 11 and water delivering orifice 12, bottom movement 3 is arranged in water strainer 4, top movement 2 is arranged on bottom movement 3, and this water meter structure also comprises electrical ball valve 5, for driving the circuit board 6 of electrical ball valve 5 and being used to top movement 2, bottom movement 3, circuit board 6 and electrical ball valve 5 that the battery of electric energy is provided.
Electrical ball valve 5 comprises reducing motor 51, valve rod 52, spheroid 53 and valve body 54, the output shaft of reducing motor 51 is connected with valve rod 52, and valve rod 52 is connected with spheroid 53, is provided with the first through hole on spheroid 53, on valve body 54, be provided with the second through hole, spheroid 53 is located in valve body 54 outsides.The principle of work of electrical ball valve 5 is: when reducing motor 51 is received after the instruction of circuit board 6, reducing motor 51 slows down, by valve rod 52 motion, drive spheroids 53 rotations, the second through hole on the first through hole on spheroid 53 and valve body 54 is when coaxial, and valve is all opened; And when spheroid 53 rotates again, the first through hole and the second through hole stagger, valve closing, thus realize the control to current break-make.This valve mechanism is simple, moves also simply, and part is few, manufactures easily, and cost is lower, and crushing is less.
The circuit structure of circuit board 6 as shown in Figure 2, in figure, RB1, RB2 and RB3 are monolithic pin, Motor_in 1 is connected with the two ends of reducing motor 51 with Motor_in 2, when RB1 is high level, when RB2 is low level, triode Q1, Q3, Q4 conducting respectively, Q4 amplifies electric current, reducing motor 51 two ends conductings, reducing motor 51 forwards are opened valve; When RB1 is low level, when RB2 is high level, triode Q2, Q5, Q6 conducting, Q5 amplifies electric current, reducing motor 51 two ends conductings, reducing motor 51 upset valve-offs.After water meter valve reaches position or closes and to put in place, because reducing motor 51 stops operating, produced larger electric current, now Q7 conducting, RB3 pin becomes low level from high level, produces and interrupts, and enters reducing motor 51 program that stops operating.
The outside surface of spheroid 53 is provided with O-ring seal 7, when valve closing, prevents that water from flowing through.
Movement 2 tops in top are provided with watch glass 8, are convenient to watch the situations such as the water yield that show on top movement 2.
