Description
Technical field
The utility model relates to gas metering field, particularly relates to a kind of tamper gas meter, flow meter.
Background technology
At present, gas meter, flow meter is mostly tongue tube pulsed gas meter, flow meter, adopts permanent magnet trigger the closed of tongue tube or disconnect, produce pulse, and the data of paired pulses calculates, thus calculate the flow of combustion gas.But the generation of tongue tube pulse is not entirely accurate, being namely turned on or off of tongue tube is not entirely accurate.When permanent magnet gradually near or when leaving tongue tube, reed is incited somebody to action adhesive gradually or is disconnected gradually under the effect of magnetic force, reed may produce shake because of external environment reason in the process, thus trigger series of pulses (i.e. Vibrating pulse), cause and repeatedly count, namely cause flow " to count " more.In addition, when permanent magnet with speed faster from tongue tube side process, reed response lag, namely reed also non-adhesive permanent magnet leave tongue tube, tongue tube fails to produce pulse in time, causes counting to omit, and namely causes flow " to leak meter ".
Therefore, the metering accuracy of the gas meter, flow meter of prior art is lower.
Utility model content
The technical matters that the utility model mainly solves is to provide a kind of tamper gas meter, flow meter, can improve the accuracy of measuring.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of tamper gas meter, flow meter, comprise two semicircle bodys, front fastening frame, rear fastening frame, guide rod, bearing, impeller, magnet steel, Hall element and two semicircle sheaths, described two semicircle bodys connect formation pipeline, described front fastening frame and described rear fastening frame have elasticity, described front fastening frame and described rear fastening frame spaced to be embedded in described pipeline and elasticity pressure holding in the inwall of described pipeline, the two ends of described guide rod are separately fixed on described front fastening frame and described rear fastening frame, and described guide rod is positioned on the central axis of described pipeline, described bearing holder (housing, cover) is located on described guide rod, described impeller is located at described bearing outer, described impeller is provided with magnet steel, described Hall element is located at outside the pipeline directly over described impeller, one end of the radial direction of described semicircle sheath is provided with reference column, described reference column is provided with triangle back-off, the other end of the radial direction of described semicircle sheath is provided with boss, chamber groove is provided with in described boss, described two semicircle sheaths are enclosed within also oppositely docking on two semicircle bodys, and described triangle back-off buckles in relative chamber groove.
Be different from the situation of prior art, the beneficial effects of the utility model are: by being built in by magnet steel on the impeller in pipeline, when fuel gas flow drive impeller rotates, Hall element can detect the motion of magnet steel, and then generation continuous data, thus can the accuracy of measuring be improved, there is structure simple, the advantage that cost is low.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of the utility model embodiment tamper gas meter, flow meter.
Fig. 2 is the side-looking structural representation after the semicircle body of the utility model embodiment tamper gas meter, flow meter and semicircle sheath are installed.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Please also refer to Fig. 1 and Tu.The tamper gas meter, flow meter of the utility model embodiment comprises two semicircle bodys 1, front fastening frame 2, rear fastening frame 3, guide rod 4, bearing 5, impeller 6, magnet steel 7, Hall element 8 and two semicircle sheaths 9, two semicircle bodys 1 connect and form pipeline 11, front fastening frame 2 and rear fastening frame 3 have elasticity, front fastening frame 2 and rear fastening frame 3 spaced to be embedded in pipeline 11 and elasticity pressure holding in the inwall of pipeline 11, the two ends of guide rod 4 are separately fixed on front fastening frame 2 and rear fastening frame 3, and guide rod 4 is positioned on the central axis of pipeline 11, bearing 5 is set on guide rod 4, impeller 6 is located at bearing 5 outer, impeller 6 is provided with magnet steel 7, Hall element 8 is located at outside the pipeline 11 directly over impeller 6, one end of the radial direction of semicircle sheath 9 is provided with reference column 91, reference column 91 is provided with triangle back-off 92, the other end of the radial direction of semicircle sheath 9 is provided with boss 93, chamber groove 94 is provided with in boss 93, two semicircle sheaths 9 are enclosed within also oppositely docking on two semicircle bodys 1, and triangle back-off 92 buckles in relative chamber groove 94.
Front fastening frame 2 and rear fastening frame 3 utilize elastic force to be fixed in pipeline 11, can be for convenience detach.
When fuel gas flow impacts impeller 6 along pipeline 11, drive impeller 6 rotated, the magnet steel 7 on impeller 6 periodically will rotate with impeller 6, and Hall element 8 periodically can detect the motion of magnet steel 7, thus produce pulse signal, and then produce continuous data.
By the way, the tamper gas meter, flow meter of the utility model embodiment is by being built on the impeller in pipeline by magnet steel, when fuel gas flow drive impeller rotates, Hall element can detect the motion of magnet steel, and then generation continuous data, thus can the accuracy of measuring be improved, there is structure simple, the advantage that cost is low.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model instructions and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
