Abstract
The utility model provides a membrane type gas meter. The membrane type gas meter comprises a machine core assembly and a metering casing. The machine core assembly is connected with an external magnet assembly, an internal magnet assembly is arranged inside the external magnet assembly and connected with a driving gear, the driving gear is engaged with a driven gear and connected with a counter assembly, and the driving gear, the driven gear and the counter assembly are all arranged inside the metering casing. The membrane type gas meter transmits the metering rotation of the machine core assembly to the counter assembly outside the casing in a magnetic transmission mode, thereby being flexible in transmission, reliable in sealing performance, high in precision and capable of ensuring the safety performance of the gas meter.
Description
Technical field
The utility model relates to a kind of gas meter, flow meter, especially a kind of diaphragm gas meter.
Background technology
Diaphragm gas meter adopts flexible thin-walled metering gas flow, it is the instrument for the metering gas volumetric flow rate, combustion gas alternately enters measuring room through distribution valve, the flexible diaphragm that promotes simultaneously in the measuring room is reciprocating, be full of the back discharged to the gas outlet, being reverse mechanism by valve converts the cyclic process of this inflation, exhaust to corresponding volume, is delivered to counter.The movement metering of existing diaphragm gas meter is rotated and is delivered to the outer counter of housing, and transmission is dumb, has influenced measuring accuracy.
The utility model content
The purpose of this utility model provides the high diaphragm gas meter of a kind of precision.
Realize the diaphragm gas meter of the utility model purpose, comprise movement group and metering shell, described movement group connects outer magnetic group, interior magnetic group is positioned at described outer magnetic group, the magnetic group is connected with driving wheel in described, is engaged with engaged wheel on the described driving wheel, and described driving wheel is connected with the counter group; Described driving wheel, engaged wheel sum counter group are located at outside the metering shell.
The outside of described counter group is provided with the counter cover.
Be provided with the surface between described counter group and the counter cover.
The beneficial effect of diaphragm gas meter of the present utility model is as follows: diaphragm gas meter of the present utility model, and by " magnetic transmission " movement metering is rotated and to be delivered to the outer counter of housing, ensuring smooth transmission, sealing is reliable, and the precision height has been guaranteed the security performance of gas meter, flow meter.
Description of drawings
Fig. 1 is the structural representation of diaphragm gas meter of the present utility model.
Embodiment
Embodiment of the present utility model is as follows: as shown in Figure 1, diaphragm gas meter of the present utility model, comprise movement group 1 and metering shell 2, described movement group 1 connects outer magnetic group 4, interior magnetic group 3 is positioned at described outer magnetic group 4, magnetic group 3 is connected with driving wheel 5 in described, is engaged with engaged wheel 6 on the described driving wheel 5, and described driving wheel 5 is connected with counter group 7; Described driving wheel 5, engaged wheel 6 sum counter groups 7 are located at outside the metering shell 2.
The outside of described counter group 7 is provided with counter cover 9.Be provided with surface 8 between described counter group 7 and the counter cover 9.
Diaphragm gas meter of the present utility model, the movement group circulated after a week, rotated by the outer magnetic group of the driving lever gear driven on the movement group, and outer magnetic group realizes rotating synchronously with interior magnetic group by the magnetic transmission, by the conversion of driving and driven gear, thereby the revolution volume is converted into meter reading in will showing.
Embodiment recited above is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; design under the spiritual prerequisite not breaking away from the utility model; various distortion and improvement that the common engineering technical personnel in this area make technical solutions of the utility model all should fall in the definite protection domain of claims of the present utility model.
