accompanying drawing explanation
Attached 1 is structural representation of the present utility model.
embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, intelligent and safe gas meter, flow meter of the present utility model, by control processor assembly 1, Safety control valve 2, fuel gas inlet 3, table body 4, gas leakage sensor 5, magnet 6, Hall element 7, flow sensor cylinder body 8, flow sensor counterweight 9, gas outlet 10, pressure transducer 11 forms.
Described table body 4 has U-shaped blast tube, described Safety control valve 2 is arranged on fuel gas inlet 3 place of U-shaped blast tube, described pressure transducer 11 is located in U-shaped blast tube, flow sensor is provided with at gas outlet 10 place of U-shaped blast tube, described flow sensor comprises the flow sensor cylinder body 8 be communicated with gas outlet, be positioned at the flow sensor counterweight 9 of flow sensor cylinder body, be separately positioned on the magnet at flow sensor counterweight two ends and the Hall element 7 between two magnets, described Safety control valve 2, pressure transducer 11 and Hall element 7 connection control processor module 1, control processor assembly is also connected with gas leakage sensor 5 and gas metering display screen, described gas leakage sensor controls to carry out Safety control valve cut out when the gas content in air being detected, the signal that described control processor assembly detects according to pressure transducer and Hall element calculates gas quantity and is shown by gas metering display screen.
The effect of control processor assembly 1 is according to gas leakage sensor 5, Hall element 7, and the signal that pressure transducer 11 is sent here carries out data operation process, realizes gas metering, security control, the effect that charging wireless messages transmits.The effect of Safety control valve 2 is effects that combustion gas was opened or closed to the control signal sent here according to control processor assembly 1.The effect of fuel gas inlet 3 connects gas pipeline, and safe measuring table is introduced in combustion gas.Table body 4, effect be connect entering out and the miscellaneous part of fixing gas meter, flow meter of combustion gas.The effect of gas leakage sensor 5 detects with the gas content in the air of gas place, when the gas content in air exceedes certain value, output signal to control processor assembly 1, after control processor assembly 1 calculation process, control Safety control valve, thus close combustion gas.The effect of magnet 6 is for Hall element 7 provides an operating fields, changes the output variable of Hall element 7 when magnet 6 moves.The effect of Hall element 7 gives control processor assembly 1 according to the displacement output analog variable of flow sensor counterweight 9 and magnet 6, after control processor assembly 1 data processing, realize gas metering and security control.The effect of flow sensor cylinder body 8 is collections that cooperation flow sensor counterweight 9 completes to gas flow.The effect of flow sensor counterweight 9 produces corresponding displacement according to the size of user's gas consumption.The effect of gas outlet 10 coordinates flow sensor counterweight 9 pairs of gas flows to gather.The effect of pressure transducer 11 gathers gaseous-pressure and exports analog variable, gives control processor assembly 1 and apply as account variable signal.
Principle of work of the present utility model is; User needs the button first pressed during use gas on control processor assembly 1, and Safety control valve 2 is opened, and now safe measuring table is in opening.When having combustion gas to flow through gas outlet 10, because the lower end air pressure of flow sensor counterweight 9 is higher than the upper end air pressure of flow sensor counterweight 9, flow sensor counterweight 9 and magnet 6 just move upward, when magnet 6 moves to Hall element 7, Hall element 7 just has variable voltage and exports, flow through gas outlet 10 flow more large discharge sensor counterweight 9 and magnet 6 just move upward more, the level that the distance nearlyer Hall element 7 of magnet 6 and Hall element 7 exports is higher, after this variable electric signal delivers to control processor assembly 1, A/D converter is had to carry out pulses switch, the pulsed frequency that during low level, conversion exports is low, the pulsed frequency that during high level, conversion exports is high.The number of pulse in the unit interval is utilized to realize flow counting.In order to realize that metering precise and safety gauging table is equipped with pressure transducer 11, the level exported when gaseous-pressure is low is low, the level exported during pressure height is high, this signal has another road A/D converter conversion after delivering to control processor assembly 1, pressure pulse after conversion and flow pulse are delivered to data operation circuit simultaneously and are carried out computing, thus realize accurate measurement.When not having combustion gas to flow through gas outlet 10, the upper end pressure of flow sensor counterweight 9 and lower end pressure equilibrium, because having certain gas leakage air gap between flow sensor counterweight 9 and flow sensor cylinder body 8, flow sensor counterweight 9 and magnet 6 just move down, Hall element 7 output low level, now control processor assembly 1 meeting self-closing safety operation valve 2 within the time of setting, realizes cutting off combustion gas source.Control processor module 1 when gas leakage signal sent here by gas leakage sensor 5 and can cut off combustion gas source by closed safe operation valve 2 immediately, thus ensure that and use gas safety.
