Abstract

The utility model relates to a water meter. Compared with the existing intelligent water meter with an IC card, the utility model is characterized in that a valve and a meter coreare respectively installed in installing holes of a housing body of the same water meter; the meter core is additionally provided with a magnetism isolating cover to prevent the affection of an intense magnetic field outside a housing; a worm gear on a valve shaft is driven with gear on worm on a motor shaft in an engaging way; outside the meter, a locking hole and a union joint of the water meter are connected in serirs by metal materials and are lead sealed to avoid the disassembly, etc. The utility model has the advantages of novel design, simple structure, and convenient fabrication and installation.

Description

Water meter

The utility model belongs to a kind of water meter, is meant the electrical integrated domestic water meter of a kind of IC-card intelligent machine especially.

The IC-card water meter of domestic production at present is that common water meter is connected valve by joint is the structure of one.The weak point of this water meter: the one, when actual installation was used, the table body was long, can not directly change original water meter, increased erected cost, and joint is too much, defective such as leak easily; The 2nd, the antimagnetic ability of water meter is just as external magnetic field cisco unity malfunction, lose the accurately function of metering of water meter; Three are to use ball valve to carry out valve as electronics, this valve when carrying out switch, motor start-up moment, big, the friction of ball valve is big, the driven by motor electric current is big, the direct interior battery of influence table serviceable life, causes shortening water meter tenure of use; The 4th, easy dismounting is difficult to guarantee the water meter measurement accuracy.

The purpose of this utility model is at above-mentioned situation, a kind of new structure and antimagnetic anti-theft measure that adopts water meter and valve to be installed on one of design, make it to have the ability of anti-outer high-intensity magnetic field, durable in use, the New Type IC Card intelligent integral domestic water meter of function such as not quick detachable.

The method that the utility model is finished is: keeping under the water meter case condition identical with the length dimension of existing water meter case water meter mounting hole and valve mounting hole being set on water meter case, water meter and valve are installed in the same housing; On housing, install special magnetism shielding hood additional, prevent of the influence of off-balancesheet high-intensity magnetic field water meter; Adopt the spool of ceramic wear-resisting chip as valve; Setting prevents the bonnet lock hole that other people dismantle, promptly after water meter be installed finished, with metal materials such as copper wire or stainless steel wire the loose joint head cap hole of water meter water inlet place with add measures such as lead sealing compresses after bonnet lock hole is connected.

The utility model has the advantages that: one, simple in structure, fabrication and processing convenience.Two, water meter and valve are installed in the same housing, and be measure-alike with original water meter case, can directly change original common water meter, provides convenience to installation.Because water meter and valve housing cast solid, solved existing IC-card water meter and how to have leaked easily, cannot say for sure when installing to inscribe between quality etc. because of joint.Three, adopt special magnetism shielding hood, improved the diamagnetic ability of water meter, help the operate as normal of water meter.Four, use ceramic cartridge, have characteristics such as be not subjected to that burn into is not aging, wear-resisting, sealing is strong, hydraulic pressure resistance power is strong, friction is little when carrying out the open and close valve, and electric current is little during the driven by motor valve switch, can reduce battery loss, prolongs water meter tenure of use.Five, adopted anti-measure of dismantling water meter privately, water meter measurement is accurate, and protection water resource, water-saving effect are played in favourable reasonable fee.Six, the huge market demand, can produce good economic benefits and social benefit.

Accompanying drawing 1 is that agent structure synoptic diagram of the present utility model, Fig. 2 are circuit theory diagrams for left view, Fig. 4 of Fig. 1 for A-A section left view, Fig. 5 of Fig. 1 for vertical view, Fig. 3 of Fig. 1.

Embodiment of the present utility model is: watch core with standard water meter performance (19) and valve (11) are installed in the mounting hole of water meter case (16) separately; the Antimagnetic hood (6) that is installed on the housing covers on watch core and the data of water meter sampler (7) that is installed on the watch core wherein; the motor bracing frame (12) that is fixed on the housing is supporting motor (8); gear on worm on the motor reel (9) and worm-gear toothing (10) engaged transmission that is installed on the valve shaft; protection case (14) is installed in above the housing; IC-card seat (1) is arranged in the case; main control board (2) is installed in below the panel of case; water meter number implement display window (3) and liquid crystal data presentation window (4) are arranged on the panel of case; be installed in the case inner face with the liquid crystal data display equipment (5) of liquid crystal data presentation window adapted; the valve chip (moving plate) (13) and the valve chip (still) (15) that are installed on the valve shaft (20) are made with stupalith; be used as valve switch; with sealing surface (27) adapted of intake tunnel in the housing, travel switch (18) and lead sealing bonnet lock hole (17) are separately positioned on the interior outer face of case.Anti-waterside (21), waterproof cover (23) and cover plate are housed on the card reader (22) of IC-card seat scratch hand (24), battery (26) is installed on the housing, is communicated with control circuit (2).Water inlet pipe (25) is the passage that pipeline water enters the table body.During work, valve is in out the position, and water flows into the table body, impulsion water meter watch core impeller drives water meter running beginning counting, has installed a small magnet on the watch core X100 indicator additional, whenever turn around with the data of water meter sampler in dry reed tube meet again once, make dry reed tube JS once by closure that magnetic is inhaled.Because of the EI battery is given governor circuit (2) power supply, the every closure of dry reed tube JS once produces the primary circuit pulse and gives the data processing that UI integrated circuit in the circuit carries out each pulse number, because the storage of KZ integrated circuit is located input through IC-card (1) and is purchased the water number certificate, just subtract the storage data of KZ integrated circuit IC-card input through the every processing pulsatile once of UI integrated circuit signal, purchase water inventory and surplus through the liquid crystal data presentation.

Use up when purchasing the water yield, storage data is zero in the KZ integrated circuit.UI integrated circuit data reduce to zero through the each closure of dry reed tube, and 8 pin output voltages make motor (8) running driven gear (10) turn 90 degrees valve-off.Travel switch (18) C2 closure makes UI integrated circuit 7 pin obtain voltage and makes 8 pin lose output voltage, and motor shuts down, and valve is in closes.

The user inserts deck (1) as the IC-card that will purchase water again and have data inputs and locates to make in the KZ integrated circuit data have been arranged, the UI integrated circuit obtains signal 8 pin output voltage signals, the motor operation driven gear is opened valve gear (10) and is forwarded 90 to when spending, travel switch (18) C2 closure, make UI integrated circuit 7 pin obtain voltage, 8 pin lose output voltage, and motor shuts down, valve must be in opening the position, normal water supply.

Adopt the metal material silk that bonnet lock hole (17) is connected with the loose joint head cap hole (28) of water meter water inlet place and add the anti-dismounting structure of lead sealing.
