Diaphragm gas meter sample count mechanism
Technical field
The present invention relates to gas meter, flow meter technical field, more particularly, to a kind of diaphragm gas meter metering sample count mechanism.
Background technology
With the fast development of gas industry, China city has generally used using pipe gas as fuel.Market today The sample count mode of upper diaphragm gas meter coordinates sensor to realize by magnet steel more.Sample count mode principle is essentially:Magnetic Steel is fixed on character wheel of counter, and tongue tube or Hall element are welded on sampling printed wiring board and are fixed on as sensor Character wheel of counter both sides.Sensor produces the state of adhesive or disconnection by the power of magnet steel magnetic force, is led to this by lead The Master Control Unit that break signal is transferred in control mainboard is counted.Chinese patent Authorization Notice No. CN201803757U, authorize On April 20 2011 day for announcing, the utility model patent of entitled " FPC samplers ", is exactly one kind therein.FPC samplers FPC signal transmission belts including batching counter framework and leeched line plug, tongue tube in soldering is distinguished in FPC signal transmission belts A and tongue tube B, the FPC signals transmission belt of tongue tube is welded by strong double-face gluing knot and is fixed on batching counter framework On.Problems be present in this sample count structure:1st, sensor and printed wiring board connect, printed wiring board and control mainboard Lead connects and the protection of the brush coating of these components needs manual operations, and efficiency is low, quality is difficult to control.2nd, face when magnet steel is in During boundary's point or the vibrations tongue tube of transportation or Hall original paper displacement, these all it is possible that the situation of output jitter from And produce the situation of miscount.3rd, this sampling structure also has the dead angle attacked by external magnet, i.e., applies one outside user Sensor is disturbed in individual magnetic field, there is when certain probability appearance counter is had good luck that sensor can not normally export pulse, so as to Controller does not count.
The content of the invention
It is weak and miscount hidden danger be present in order to solve the antimagnetic interference performance of prior art membrane type gas meter, flow meter sample count device Technical problem, the present invention provide it is a kind of meets stabilization and antimagnetic iron attack simple production process diaphragm gas meter metering use Sample count mechanism.
The technical scheme is that:A kind of diaphragm gas meter sample count mechanism, including gas meter upper casing body, be arranged on Print wheel component in gas meter upper casing body and the control board being arranged on below print wheel component, the digit wheel of print wheel component are provided with Several magnet steel, control board are provided with sampling sensor I and sampling sensor II, sampling sensor I and sampling sensor II It is close to each other, and positioned at the diametric(al) of digit wheel.Undesired signal transmission board, eliminates intermediate link, eliminates influence and adopts The hidden danger of sample count accuracy.Raw material are saved simultaneously, production technology is shortened, reduces production cost, improve production Efficiency.
Preferably, control board is additionally provided with antimagnetic attack sensor, antimagnetic attack sensor is located at sampling sensor Lower section, magnet steel, sampling sensor I, sampling sensor II and antimagnetic attack sensor project to vertical plane from top to bottom in straight Line arranges.
Preferably, the distance H of sampling sensor I and magnet steel is 5mm-15mm, antimagnetic attack sensor senses with sampling The distance between device II D is 15mm-20mm;Anti- external magnetic field attack effect is good, it is ensured that sample count is accurate.
Preferably, the induced flux of sampling sensor I is 0.5mT-4mT;The induced flux of sampling sensor II For 1.5mT-5mT;Antimagnetic shake effect is good.
Preferably, magnet steel is 1-4, it is uniform along the wheel rim of digit wheel.
Compared with prior art, the beneficial effects of the invention are as follows:The counting of collection need not be believed by signal sampling plate Number control board is transferred to, directly by control board acquisition counter signal, eliminates intermediate link, eliminate influence sampling The hidden danger of count accuracy, saves raw material.Magnetic sensing element directly welds with control board, is adapted to SMT paster techniques (electronic circuit surface installation technique), soldering reliability are good.Smearing protection adhesive process is eliminated, production cost is reduced, improves Production efficiency.Stabilization and anti-external magnetic field attack effect are good, ensure that sample count is accurate.
