Specific embodiment

What the present invention was realized in：In mechanical water meter, by the discharge of water meter, the impeller of Jing water meters rotation or The mechanical detection metering of volumetric metering box, the gear transmission of Jing measurement gear groups (36), will count in measurement gear box (49) Value shows integrated flow and instantaneous delivery reading with mechanical digital character wheel (52) or the numeral on gear top；In the water yield In variable transfer wheel, an appropriate metered amount grade is set, such as conventional 15mm latus rectum water meters of family are set in 0.1 On cubic meter measurement wheel, quantitatively (64) are taken turns as counting.It is exactly 1 cubic metre of current that this counts quantitative wheel (64) and rotates a circle Amount, as the charge base unit that each wheel supplies water.If the more big orifice water meter of bigger output, is correspondingly just located at higher On the measurement wheel such as 1 cubic metre or 10 cubic metres of metering level.On the wheel shaft for counting quantitative wheel (64), in differing heights position Put, on the position of different angle, be provided with for ease of three of the loop control quantitative control breach successively in rotation：Control lacks Mouth 1 (66), control breach 2 (67), quantitative breach 3 (68)；One quantitative breach turn round after followed by next quantitative breach； It is correspondingly spring swaging clamp 1 (15), spring swaging clamp 2 (16), spring swaging clamp 3 (17) with each quantitative breach；By Spring Card Knife 1 (15), spring swaging clamp 2 (16), the middle bent of spring swaging clamp 3 (17) so as to which the spring that can be stretched as length is used.Bullet Spring swaging clamp 1 (15), spring swaging clamp 2 (16), the combination of spring swaging clamp 3 (17) are arranged on control arm (13).

It is illustrated with reference to illustration.In illustration, in order to show the structure of major part more clear, in figure Appropriate omission is made into the part for being not required to make to state in some secondary or water meter original structures, to some parts, such as spring The shape of swaging clamp, position and numbering, are that diagram is convenient, also different；Simultaneously for above having made many detailed descriptions , description below has just made appropriate omission.

Fig. 1 is the Mechanical course structural representation of smart card water meter, and Fig. 1 status displays are magnet on control arm (13) 1 (11) repels each other with magnetic guiding valve (9) same sex, and magnetic guiding valve (9) is by lever (8), pole (27), through the ear on rubber bowl (7) (30) guiding valve (32), pulls rubber bowl (7) upwards, and the discharge orifice (29) on rubber bowl (7) is opened, and valve (5) is in unlatching State.Fig. 2 is the Mechanical course structural representation of smart card water meter, top frame for movements of the Fig. 2 to Fig. 1, control arm (13) and Associated counting quantitatively takes turns (64) and quantitative axle (65), locking closure mechanism have and more clearly indicate.Below to the work of Fig. 1, Fig. 2 It is been described by as process.The state of inlet valve (5) is first set to close, such as Fig. 5 states：Control arm is fixed with two on (13) Polarity inverted magnet 1 (11) and magnet 2 (12) each other；Due to magnet 2 (12), there is a natural attraction between the sexes with magnetic guiding valve (9), magnetic guiding valve (9) The guiding valve (32) of the other end is acted on by lever (8), pole (27), the guiding valve (32) of ear (30) through on rubber bowl (7) The discharge orifice (29) on rubber bowl (7) is compressed, water is entered in rubber bowl (7), rubber bowl (7) closing valve mouth (81), valve (5) Rubber bowl (7) external and internal pressure of side is identical, rubber bowl (7) bottom and the pressure differential on the outside of valve (5) is formed, so as to close water inlet Valve (5).Controlled post (34) effects of switch K1 (25) in this state, control arm (13), switch K1 (25) closes, electricity Electricity on road plate (1), circuit power indication light diode (59) instantaneous light emission, if circuit board (1) has stored enough water rates, Then only need circuit board (1) that valve opening water supply instruction is sent by reducing water rate, if the water rate of circuit board (1) is not enough, need with intelligence Card (93) is connected the formula that interacts with circuit board (1) and communicates, the water rate in smart card (93) is passed into circuit board (1), by electricity Road plate (1) sends valve opening instruction.Display screen (96) only shows and deduct fees use and remaining sum.If smart card (93) and circuit board (1) all without water rate, can resume water supply by emergence button (3) overdraw；During valve opening, circuit board (1) gives micro speed reducing motor (19) electricity, unidirectional drive arm (83) the drive control arm in the rotary shaft (21) of micro speed reducing motor (19) in positive direction (13) counting is run into successively on spring swaging clamp 3 (17), on control arm (13), the inclined-plane of the spring swaging clamp 1 (15) of spring swaging clamp 2 (16) The quantitative axle (65) of quantitative wheel (64), and pass through quantitative axle (65) using elastic " bending over "；On the other hand, on control arm (13) Magnet 2 (12) is separated with the magnetic guiding valve (9) across valve frame (10), and magnet 1 (11) is turned to above magnetic guiding valve (9), but less than The center line of magnet 1 (11) and magnetic guiding valve (9), magnet 1 (11) repels each other with magnetic guiding valve (9) same sex, and magnetic guiding valve (9) is by lever (8), pole (27) acts on the guiding valve (32) of the other end, and the guiding valve (32) of ear (30) leaves earial drainage through on rubber bowl (7) Hole (29), and drive rubber bowl (7) to upwardly open valve (5)；Unidirectional drive arm (83) departs from control arm (13), spring swaging clamp 1 (15) quantitative axle (65) is withstood；Unidirectional drive arm (83) is rotated further to switch K2 (26) place, by the switch K2 of normally closed switch (26) disconnect, circuit board (1) power-off, micro speed reducing motor (19) power-off, a valve opening operation is completed.In water supply process, Count quantitative wheel (64) to rotate, spring swaging clamp 1 (15) slips over control breach 1 (15), spring swaging clamp 2 (16) and slips over control breach (16), control arm (13) is moved by magnet 1 (11), magnet 2 (12) and the effect of magnetic guiding valve (9) to closing direction, switchs K2 (26) disengage with unidirectional drive arm (83), switch K2 (26) recovers normally closed state；Come when spring swaging clamp 3 (17) is parked in rotation Control breach 3 (68) on, supply water so far, according to setting, an existing wheel supply water more than half, and continue to supply without a break Water；When spring swaging clamp 3 (17) is moved near quantitative axle (65) center line, control column (34) will switch K1 (25) and close, circuit Electricity on plate (1), the charge that a new round is started again is deducted fees startup valve opening.So repeat the charge -- water supply -- of the another wheel of a wheel Charge -- water supply process.

One wheel normal water supply, Spring Card swivel is dynamic and control arm (13) is exactly spring swaging clamp 1 by the distance of driving recovery (15) distance of the edge of a knife to the edge of a knife of spring swaging clamp 3 (17), only several millimeters.In the normal water supply operation for not owing water rate, close The situation of valve closing door can not possibly occur, or few generation！The operation of smart card water meter is simply supplied water instant, instantaneous halfway in a wheel Water rate is checked and accepted, is started water meter controlling organization and is recovered to new round service position, instantaneous operation was less than one second.Come from management view Say, smart card techniques coupled computer management software can pole be readily accomplished the big rule of water meter of the present invention in a very big region Mould supplies water and manages concentratedly, controls, charging, including the water fee management of multi-ladder water price.

Fig. 4 is the smart card water meter structural representation for there was only a control magnet on control arm (13), i.e., only used one Magnet 1 (11), has used less a magnet 2 (12), but increased one from closing in valve frame (10) internal spool valve (32) top Disconnected spring (48).A strong magnet has been used due to few, cost has been reduced；The sharpest edges of this scheme are, in control arm (13) when being removed, valve (5) still can be located in off position naturally.The course of work of Fig. 3 and almost complete phase described in Fig. 1 Together.The difference is that only, due to only having used one to repel each other in the same sex magnet 1 (11) of state with magnetic guiding valve (9), magnet 2 (12) effect is replaced by automatic shutoff spring (48).The course of work is set forth below：Have on the confession water passage (53) of water meter and do not adding The valve (5) being automatically switched off without electricity during control, the inner structure of valve (5) is by valve body (6), rubber bowl (7), lever (8), magnetic guiding valve (9), pole (27), automatic shutoff spring (48) composition, are valve frame (10) above inner structure；Rubber bowl has pilot hole on (7) (28), discharge orifice (29), ear (30), having in rubber bowl (7) bottom increases the reinforcing plate (31) of compression strength；Magnetic guiding valve (9) Automatic shutoff spring (48) above the guiding valve (32) and guiding valve (32) of the other end is acted on by lever (8), pole (27)；Valve (5) external structure has control arm (13), there is magnet 1 (11), switch K1 (25), switch K2 (26) on control arm (13), and installs Micro speed reducing motor (19) on antimagnetic valve rack (63), has list in the rotary shaft (21) of micro speed reducing motor (19) To actuating arm (83), when unidirectional drive arm (83) drive control arm (13) makees positive direction valve (5), magnet 1 (11) is across valve Door frame (10) repels each other with magnetic guiding valve (9) same sex, magnetic guiding valve (9) downwards, magnetic guiding valve (9) by lever (8), pole (27), pierce into The guiding valve (32) of ear (30) drives rubber bowl (7) to move upwards, and guiding valve (32) decontrols discharge orifice (29), while compressing upwards certainly Shut-off spring (48), so as to opening valve (5)；The magnet 1 of magnet 1 (11) and the respective center line of magnetic guiding valve (9) is not turned to completely (11) and magnetic guiding valve (9) same sex mutual expelling force, there is provided the kinetic energy that control arm (13) is rotated to closing direction；So as to close Energy needed for valve (5), is deposited with displacement and automatic shutoff spring (48) that magnet 1 (11) repels each other with the same sex of magnetic guiding valve (9) In the kinetic energy for being compressed；Control arm (13) is repelled each other active force by the same sex of magnet 1 (11) and magnetic guiding valve (9) in water supply process, is made Opposite direction is closed the control that has of valve (5) and is rotated, and charge and the process for controlling and Fig. 1 are identicals.Supply water by the end of, magnet 1 (11) is rotated away from magnetic guiding valve (9) top, automatic shutoff spring (48) release compression stress, and magnetic guiding valve (9) is passive upwards, automatic shutoff Spring (48) band movable pulley (32), rubber bowl (7) are moved downward, and guiding valve (32) compresses discharge orifice (29), rubber bowl (7), so as to Shuttoff Valve (5).Other courses of work are with Fig. 1 with regard to identical.
