Embodiment
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model
The foundation of limitation.
Embodiment.A kind of gas meter, flow meter of theft-proof gas gas, as shown in Figures 1 to 4, including the rotation detection of air inlet 1, bonnet
Device 2, counter wheel rotation detection device 3 and wiring board 20, magnetic valve 4, the bonnet rotation detection device are provided with air inlet 1
2 include bonnet 5 and are located at the bonnet rotation detection proximity switch 6 of the side of bonnet 5, and bonnet 5 is provided with bonnet sensing iron plate 7, institute
The counter wheel rotation detection device 3 stated includes counter wheel 8 and detects proximity switch with the counter wheel rotation that sets for being located at the side of counter wheel 8
10, counter wheel 8 is provided with counter wheel sensing iron plate 9, and counter wheel is connected by transmission device 11 with bonnet 5, the wiring board 20
The lower section of counter wheel 8 is located at, single-chip microcomputer is provided with wiring board 20, wiring board 20 passes through wire and bonnet rotation detection device 2, counting
Wheel rotation detection device 3 and magnetic valve 4 connect.
Described transmission device 11 includes gear train 12 and linkage 13, and the gear train 12 includes the biography being sequentially connected
Moving gear A14, in-line gears A15, travelling gear B16, in-line gears B17, in-line gears C18 and linkage 13, driving cog
Wheel A14 is connected with linkage 13, and in-line gears C18 is provided with socket bolt 19；Described counter wheel rotation detection device 3 one
Side is provided with bolt 21；Described counter wheel rotation detection device 3 is fixedly connected by bolt 21 with socket bolt 19.
Operation principle of the present utility model, the wiring board provided with single-chip microcomputer is arranged on below diaphragm gas meter counter wheel
On outer casing inner wall, combustion gas, into the metering movement 22 in gas meter, flow meter electricity box, measures the diaphragm in movement 22 in pressure by air inlet 1
