Description

The Based Intelligent Control gas meter

Technical field

The utility model relates to a kind of flow measurement device, more particularly, relating to a kind of electricity that can take off works, the instantaneous work of circuit in the air feed process, carry out air feed condition intelligent distinguishing, when finishing predetermined air demand or not satisfying the air feed condition, do not need supply capability can automatically shut down the Based Intelligent Control gas meter of valve in the gas meter.

Background technology

The gas meter that current stage is public mainly contains three kinds, and first kind is the mechanical type gas meter, and main mechanical type gas meter is the membrane type gas meter, and second kind is intelligent gas meter, and the third is the teletransmission gas meter.Intelligence gas meter and teletransmission gas meter are stack non-electricity measure instrument and smart electronics circuit on the mechanical type gas meter, thus the mechanical/electrical subset that constitutes.On principle of work, the mechanical type gas meter of main flow uses the airflow volume by gas meter such as " volumetric method " measurement, and shows instantaneous delivery and integrated flow reading by the numeral on mechanical digital roller (character wheel) or the gear.The metering of mechanical gas table is reliable, manually check meter to the doorstep but rely on fully, the raw data acquisition reliability is not high, dependency degree height to collection personnel and user, also can be because of the manual various human factors such as raw data mistake, manual entry mistake of gathering, cause data corruption, the original backwardness of ladder of management, efficient is not high.From above-mentioned narration as can be known, general mechanical type gas meter lacks strong management and executive means.The intelligent gas meter of present stage and teletransmission gas meter, the flow signal that the electric detecting technology of use non electrical quantity is measured mechanical gas meter converts electric signal or light signal or magnetic signal to, finally still convert electric signal to, for example on the mechanical part that rotates, permanent magnet is installed, tongue tube is installed at close position, non electrical quantity machinery Measuring and testing data with gas meter convert the pulse number electric quantity data that electronic installation can be operated, discern to.Electric quantity data is sent to the centralized data processing center with lead, Here it is teletransmission gas meter; The teletransmission gas meter does not have by-pass valve control usually, only checks meter, and directly charge is not controlled, and equally lacks the management executive means yet.If superposition intelligence control circuit on gas meter, above-mentioned tolerance electric signal is carried out computing, and in table the various electrically operated valves such as ball valve, stop valve, ceramic valve, gate valve of mounted valve such as solenoid valve, pilot valve or Motor Control, by opening or valve-off is controlled tolerance by gas meter, thereby manage and charge, gas meter user and gas company use IC-card, cable network or the transmission of out of Memory medium is paid the fees or other condition air feed permission, Here it is intelligent gas meter, intelligent gas meter has the management executive means.Intelligence gas meter and teletransmission gas meter all bring great convenience for user and air feed supvr, but also exist a lot of not enough, electronic equipment has the characteristics of necessary 24 hours uninterrupted power supplies, whether whether air feed all must give electric power supply to gas meter all the time incessantly, even just atomic little power supply under the circuit dormant state, but must power supply.No matter how advanced how stable circuit is,, how perfect function is if do not power, and all will stop the work that the tolerance conversion of signals becomes electric quantity signal, will cause do not count, few counting, the work of intelligent gas meter and teletransmission gas meter is just malfunctioning!

This management executive means has become the negative factor of management on the contrary.Great structural hidden danger that Here it is! Also have a great principle defective, promptly intelligent gas meter and teletransmission gas meter, a gas consumption has mechanical reading and two kinds of data of electronical reading simultaneously.Daily air feed, use gas, the management of paying the fees all is an electronic data, and electronic data is the adulterium product of mechanical data, with mechanical data must can not be identical, practice for many years is verified, at same intelligent gas meter, the teletransmission gas meter exists the machinery metering to show that reading and electronics display digit reading this two or more are with under the gas data conditions, large batch of intelligent gas meter reaches continual air feed of several years and with in the gas management in user family, to stop fully because of power supply, equipment, artificially, the data that reasons such as environment cause are inconsistent, in theory, on the principle, all be impossible in the practice! One shows two kinds of different metering readings with destiny according to two kinds: paying is based on electronic data, and control air feed usefulness gas also is electronic data; If occur and the inconsistent then data for reference only of mechanical data, this is this basic purpose of legislation of violating the unified measurement standard of national measurement Law to electronic data in actual management! Also become one of managerial confusion equipment root out of control.This is the principle error of existing intelligent gas meter, or great structural defect.Therefore, the electric detecting technology of researching and developing a kind of non electrical quantity that breaks traditions relies on working power, can take off electricity work, with destiny according to single, metering unifiedly show, reliable and stable, prevent illegal non-destructive attack, do not have electricity or do not power yet must energy shutoff table in valve, adapt to present economy development level and the novel intelligent gas meter of quite a long period from now on, just become certainty.

Embodiment

The utility model is achieved in that in mechanical gas meter watchcase, airshed by gas meter detects metering through gas meter, variable transmission accumulation, show integrated flow and instantaneous delivery reading with the numeral on mechanical digital roller (character wheel) or the gear, in the variable transfer wheel of tolerance, set a quantitative grade of suitable metering, for example be set on 0.1 cubic metre of (hundred kilograms) measurement wheel, quantitatively wheel (9) of counting is set, this counting quantitatively wheel (9) can be a gear, also can be roller (character wheel), this counting quantitatively wheel (9) rotation one circle be exactly 1 cubic metre of airshed.At counting quantitatively on the position of the wheel shaft center on wheel (9) axle and different length position, different angles, be provided with for ease of three of the cycle control quantitatively quantitative breach 1 (12) of control breach, quantitatively breach 2 (13), quantitative breach 3 (14) successively in rotating, then next more quantitatively breach after a quantitative breach turns round; Corresponding one by one with each quantitative breach is that blade has spring swaging clamp 1 (15), spring swaging clamp 2 (74), the spring swaging clamp 3 (75) that spring, length can stretch; The homophase of per two spring swaging clamps spaces from the diameter that is slightly larger than or equals to count quantitative wheel (9) axle in three spring swaging clamps, guarantees to have only a spring swaging clamp contact counting quantitatively axle or a quantitative breach face of wheel (9) at any time.Three spring swaging clamps are installed on the knife rest (76) that is fixed as one with magnet control auxiliary (16), cover knife rest (76), spring swaging clamp 1 (15), spring swaging clamp 2 (74), spring swaging clamp 3 (75), the quantitative wheel of counting (9) (141) magnet being controlled auxiliary (16) and be fixed as one with magnet control auxiliary and be integrated in together on the seal isolation box (46); The control auxiliary magnet 1 (69) of magnet control auxiliary (16), there is a natural attraction between the sexes across seal isolation box (46) with magnet control arm magnet 1 (82) on the magnet control arm (77).Auxiliary magnet can be a magnet, and there is a natural attraction between the sexes with magnet control arm magnet 1 (82) or magnet control arm magnet 2 (83); When adopting the pilot valve of Fig. 1, also can be two mutual inverted magnet of polarity: control auxiliary magnet 1 (69), control auxiliary magnet 2 (70), there is a natural attraction between the sexes with magnet control arm magnet 1 (82) and magnet control arm magnet 2 (83), same moved further; Can satisfy the magnetic attraction of appropriateness between magnet control auxiliary (16) and the magnet control arm (77) at the last needs of suitable distance across seal isolation box (46).When not needing gas barrier, auxiliary shell (41), magnet control auxiliary (16), shell internal frame (133), control auxiliary magnet 1 (69) etc. just are out of use; From security, be contained in the gas meter, all be contained in the seal isolation box (46) all Mechatronic devices best.Following effect magnet (47) in magnet control arm magnet 1 (82) on magnet control arm (77) and the valve rack box (78) is when mutual edge distance far there is a natural attraction between the sexes magnetic force is more weak mutually, spring swaging clamp on the magnet control auxiliary (16) is counted quantitative wheel (9) to be stopped, magnet control arm (77) also just is blocked simultaneously; But this oligodynamic action has caused the friction force loss to the metering rotating force of counting quantitative wheel (9), but also has been converted into the metering rotating force in the quantitative breach face that rotates simultaneously, has made adequate compensation.When continuing air feed, counting quantitatively wheel (9) rotates, quantitatively breach 1 (12), quantitatively breach 2 (13), let slip spring swaging clamp 1 (15), spring swaging clamp 2 (74) successively, quantitatively spring swaging clamp 3 (75) is blocked in the position of breach 3 (14), second place K switch 2 (80) closures, intelligent circuit board (17) powers on, electronic circuit is through reception information or handle prestored message and intelligent distinguishing, if meet next round air feed condition, intelligent circuit board (17) starts driving circuit, and motor (29) powers on, drives train of reduction gears (27); Clutch magnet (65) powers on, the clutch hole (73) of scalable actuating rod (63) from magnet control arm (77) axle stretched into the clutch action hole (72) on clutch gear (62) axle; Motor (29) drives clutch gear (62) by train of reduction gears (27), stretch in the clutch action hole (72) on clutch gear (62) axle under the situation at scalable actuating rod (63), drive magnet control arm (77), magnet control arm (77) is rotated back the initial state of new round air feed, magnet control auxiliary (16) also rotates back the initial state readiness before of new round air feed, spring swaging clamp 2 (74) on the magnet control auxiliary (16), spring swaging clamp 1 (15) blade front end retraction, compress self length successively by the quantitative wheel (9) of counting, spring swaging clamp 1 (15) replaces being pressed in the spring swaging clamp 3 (75) on the quantitative breach 3 (14), being pressed in counting quantitatively takes turns on the quantitative breach 1 (12) that does not rotate in place as yet on (9) axle, it is quantitative that the surplus and new that continues to finish the epicycle air feed is so again taken turns air feed.If intelligent circuit board (17) powers on, through reception information or processing prestored message and intelligent distinguishing, if do not meet next round air feed condition, circuit alarm requires subscriber payment to supplement with money, continues air feed this moment; If intelligent circuit board (17) fails to power on, fail to differentiate, or differentiate but power driving circuit fail the starting (no electricity or power shortage), also continue air feed this moment, counting quantitatively wheel (9) is rotated further, turn to quantitative breach 3 (14) until the quantitative wheel of counting (9) and let slip spring swaging clamp 3 (75), this quantitative air feed is finished.This moment magnet control arm magnet 1 (82) with effect magnet (47) down mutually mutual edge distance closely there is a natural attraction between the sexes that magnetic force is strong, therefore inhale together mutually, air intake valve (71) is stablized and is closed.At this moment magnet control arm (77) just forwards the pass valve position to.The concrete still pilot-operated type valve of rotary shaft valve (for example ball valve, ceramic valve etc.) that adopts, the perhaps course of work of other kind valve, the back is illustrated respectively again.If after second place K switch 2 (80) closures, intelligent circuit board (17) power on and fail to meet the air feed condition, continue air feed again to the valve blocking interval, the user goes to have paid expense again, close valve back primary importance K switch 1 (81) closure of stopping the supple of gas or steam this moment, intelligent circuit board (17) powers on, through reception information or processing prestored message and intelligent distinguishing, if meet new round air feed condition, intelligent circuit board (17) starts driving circuit, and motor (29) powers on, drives train of reduction gears (27); Clutch magnet (65) powers on, the clutch hole (73) of scalable actuating rod (63) from magnet control arm (77) axle stretched into the clutch action hole (72) on clutch gear (62) axle; Motor (29) drives clutch gear (62) by train of reduction gears (27), stretch in the clutch action hole (72) under the situation at scalable actuating rod (63), drive magnet control arm (77), magnet control arm (77) is rotated back the initial state of new round air feed,, spring swaging clamp 3 (75), spring swaging clamp 2 (74), spring swaging clamp 1 (15) compress self length successively by the quantitative wheel (9) of counting, spring swaging clamp 1 (15) is pressed in counting and quantitatively takes turns on (9) axle, air intake valve (71) is opened, the quantitative air feed of a beginning new round.

Situation when different valve is adopted in narration respectively below: when 1, adopting pilot-operated type air intake valve (71) in the gas meter, following effect magnet (47) in the described control gear can slide up and down in seal isolation box (46), with following effect magnet (47) interactional magnet control arms (77), its rotating shaft (93) is on seal isolation box (46), magnet control arm (77) can be gone up left-right rotation at seal isolation box (46), is fixed with two the inverted each other magnet control arm of polarity magnet 1 (82) and magnet control arm magnet 2 (83) on the magnet control arm (77); Act on magnet (47) is positioned at lever (50) the connection other end at its middle part by balance pivot (48) glue guiding valve (53) down, glue guiding valve (53) is inserted in the inner frame (51) on the valve rubber bowl (54), is used for upwards unclamping pulling or compresses valve rubber bowl (54) downwards; Inner frame (51) is fixed as one with the big skeleton of rubber bowl (52), the little skeleton of rubber bowl (56), between the big skeleton of rubber bowl (52), the little skeleton of rubber bowl (56) valve rubber bowl (54) is arranged, have pilot hole (49), valve rubber bowl (54) bottom that discharge orifice (84) is arranged on the valve rubber bowl (54); Form a pressure chamber (85) in the valve rubber bowl (54), pressure chamber (85) are linked up valve air intake opening and gas outlet through pilot hole (49) and discharge orifice (84); There is a natural attraction between the sexes with acting on magnet (47) down when magnet control arm magnet 1 (82), under act on magnet (47) and upwards slide, drive glue guiding valve (53) to lower slider, compress valve rubber bowl (54) and compress the discharge orifice (84) of bottom, close air intake valve (71); When the magnet control arm magnet 2 (83) and following effect magnet (47) same sex are repelled each other, under act on magnet (47) to lower slider, drive the discharge orifice (84) that glue guiding valve (53) upwards slided, unclamped the bottom, and upwards spur valve rubber bowl (54), so just opened air intake valve (71).When 2, adopting rotary shaft valve (ball valve, ceramic valve etc.) in the gas meter, the following effect magnet (47) of fan-shaped strong magnet is fixed on the seal isolation box (46), equally also is fan-shaped strong magnet with acting on the interactional magnet control arm of magnet (47) magnet 1 (82) down; Be fixed with the turning handle (99) of controlled valve in the rotating shaft of rotary shaft valve (93), the rotation axis of magnet control arm (77) be enclosed within clutch gear (62) the axle on, the axle of clutch gear (62) is enclosed within again in the rotating shaft (93), and promptly magnet control arm (77) and clutch gear (62) are center of rotation with rotating shaft (93).Magnet control arm (77) and turning handle (99) are done the idle running displacement less than 90 degree, about 70-85 degree each other in control and in starting, and rotate 90 degree by magnet control arm (77) promotion turning handle (99) and open or turn-off air intake valve (71) after the idle running displacement.Therefore on turning handle (99), be provided with position-limiting action portion 1 (88) and position-limiting action portion 2 (89); Or position-limiting action portion is located on the magnet control arm (77), be position-limiting action portion 3 (90), position-limiting action portion 4 (91), it act as magnet control arm (77) do idle running displacement with respect to turning handle (99) less than the about 70-85 degree of 90 degree after, promote turning handle (99) rotation displacement 90 degree again, open or close air intake valve (71).Because driving valve is an inverse process with closing valve, when opening air intake valve (71), need import power, when closing air intake valve (71), only need to discharge to draw back the magnetic force that there is a natural attraction between the sexes and create conditions when this magnetic force is small, to be controlled, when this magnetic force is powerful, be used to close valve and get final product.Motor (29) drives clutch gear (62) by train of reduction gears (27), drive in two kinds of situation: the one, Open valve, stretch under the middle situation in clutch action hole (72) for clutch magnet (65) power supply, scalable actuating rod (63), motor (29) drives clutch gear (62) and magnet control arm (77) by train of reduction gears (27), separates the magnet control arm magnet 1 (82) and following effect magnet (47) that there is a natural attraction between the sexes; The 2nd, open the shell of locking, under clutch magnet (65) no power situation, electric motor starting is by train of reduction gears (27) train of reduction gears (27), reverse driving reduction gearing (108), drive dead bolt (110) open be enclosed in together gas meter on the locking of shell (1) and gas meter lower casing (107).The situation of clutch magnet (65) also can be divided into three kinds: the one, when energising, magnet control arm (77) and clutch gear (62) are connected as one co-rotation (Open valve) under motor (29) drives by train of reduction gears (27); The 2nd, there is a natural attraction between the sexes closes valve (valve-off after quantitatively air feed is finished) for leave when no power magnet control arm magnet 1 (82) and effect magnet (47) down; The 3rd, motor (29) the reverse driving train of reduction gears of energising (27) of leaving when no power is opened the locking of shell.Some gas meter lead sealing closure, in order to solve another difficult problem credit lead sealing problem of management, the utility model is airtight with whole gas meter especially: be provided with the dead bolt (110) of tongue spring with lock (109) under valve rack box (78), dead bolt (110) is positioned on valve rack box (78) below;
