Description
Technical field
The utility model device belongs to the metering outfit field of domestic gas.Be specially adapted to adopt the civilian safety-type diaphragm gas meter of magnetic card (IC) formula.
Background technology
The present family expenses diaphragm gas meter of China, therefore the demand of IC-card family expenses diaphragm gas meter that particularly has pre paid functionality all has higher requirement to the security of such gas meter, flow meter and the overall utility of outward appearance still in sustainable growth.The civilian diaphragm gas meter of the IC-card formula of producing in the prior art at home generally is to adopt to install electric controller in addition additional on the basis of base table.For example in the gas meter, flow meter of prior art, be to adopt output shaft to drive character wheel to count the gas amount that shows, and the civilian diaphragm gas meter of IC-card is to change the transmission gear on the output shaft into sampling disc type (see accompanying drawing 1,2), in base table 1 front an electric appliance control box 8 is housed, big wiring board 9 parts are contained in the middle part of electric appliance control box 8, battery 10 is contained in the bottom of electric appliance control box 8, on the sampling dish 6 in the table body magnet steel 4 is housed and comes adhesive tongue tube 5, then signal is shown gas flow by the controller of installing on display window.The major defect of this gas meter, flow meter is a unreasonable structure, because the counting of gas flow, be that flow by gases in the fuel chamber 11 passes out metering signal outside the fuel chamber 11 by output shaft 2, and put down in writing by count table, because the inside and outside wall middle part in fuel chamber 11 is provided with output shaft hole, the output shaft of installing in the output shaft hole place 2 is that movable sealing sleeve 3 connects, thus when use, cause the abrasion of motive seal easily, thereby produce the leakage of combustion gas and exist hidden danger.This device is to add electric appliance control box 8 in addition on former base table 1 in addition, so shortcoming such as the not compact and outward appearance of gas meter, flow meter one-piece construction is not good.
Goal of the invention and content
The purpose of this utility model is to propose a kind of structural design advantages of simple, safe and reliable and compact, and gas consumption chamber is independent sealing in the table body, and uses the safety-type diaphragm gas meter apparatus of magnetic card.
According to the purpose of this utility model, the safety-type diaphragm gas meter apparatus of the employing magnetic card that we proposed is to have carried out more rational design and transformation at weak point of the prior art.It at first is structure to output shaft 2 in base table fuel chamber 11, the transmission information of magnet steel 4, and the sample mode of tongue tube 5, all adopt the structure of relative close type to install, therefore having eliminated unsafe output shaft 2 sealing shroud 3 parts movingly, secondly is that each parts in the electric appliance control box 8 are transformed, and it is smaller and more exquisite reasonable that former electric appliance control box 8 is made, that installs is compacter, makes this gas meter apparatus use more convenient and safety.Below we with reference to the accompanying drawings 3.4 pairs of safety-type diaphragm gas meter apparatus of the present utility model be described in detail.Can find out that by accompanying drawing 3.4 this device is to have carried out necessary transformation on the gas meter, flow meter basis of prior art.Safety-type diaphragm gas meter apparatus of the present utility model should include watchcase, following watchcase, epithelium, valve gap, valve seat, combination of devices such as gear train form, gas consumption chamber 11 is equipped with on base table 1 top at diaphragm gas meter, front end at output shaft 2 is equipped with permanent magnet 4, in gas consumption chamber 11 outsides electric appliance control box 8 is housed, tongue tube 5 is housed respectively in electric appliance control box 8, little wiring board 7 parts such as grade, it is characterized in that connecting for the magnet-free wall trapping that does not communicate between gas consumption chamber 11 and the electric appliance control box 8, front end in gas consumption chamber 11 on the output shaft 2, and distance is the 1-10mm place between output shaft 2 central axis, permanent magnet 4 is housed, spacing is answered 2-9mm between permanent magnet 4 and the tongue tube 5, in the electric appliance control box 8 that gas consumption chamber's 11 outer walls are adorned, tongue tube 5 is housed respectively, little wiring board 7, big wiring board 9 electric components are equipped with battery 10 in the upper end of base table 1.
According to above-mentioned we can clearly recognize the description of the utility model safety-type diaphragm gas meter apparatus, principle of work of this device and process are in gas consumption chamber 11, gear train by the gas-flow momentum drives output shaft 2 rotations, and be installed in the permanent magnet 4 on the output shafts 2 in the gas consumption chamber 11, be to rotate along doing circumference with the inwall plane of electric appliance control box 8 joining gas consumption chamber 11, in the electric appliance control box 8 that gas consumption chamber 11 outer walls are installed, tongue tube 5 is housed and little wiring board 7 waits other electric components, and the permanent magnet 4 on the output shaft 2 and tongue tube 5 only a wall every (for no magnetic material preparation), when combustion gas (is example with the rock gas) amount of flow is enclosed by gear train driving output shaft 2 and permanent magnet 4 revolutions moving, the tongue tube 5 that then attracts to be installed in the electric appliance control box 8 counts once, so just the gas-flow output by gas consumption chamber 11 can be put down in writing accurately, and, convert metering signal to photosignal and be presented on the surperficial display screen by electric components such as little wiring board 7 and big wiring boards 9.In order to make more compact and reasonable of the utility model safety-type diaphragm gas meter apparatus, we also with big wiring board 9 under the condition that does not change function, big wiring board structural reform is little and be installed in top in the base table 1, and battery 10 also is equipped with on the top in base table 1 simultaneously.
Adopt the utility model safety-type diaphragm gas meter apparatus, compare with the prior art gas meter apparatus, has intrinsic safety holotype diaphragm gas meter structural design advantages of simple, safe and reliable and compact, gas consumption chamber is independent enclosed construction type in the table body, therefore in the long-term use of gas meter, flow meter, do not have the wearing and tearing of motive seal or aging and produce the leakage of combustion gas, improved the safety in utilization of gas meter, flow meter.The utility model safety-type diaphragm gas meter apparatus dwindles former electric appliance control box in addition, and the outward appearance that makes gas meter, flow meter is compact and reasonable more.
