Description
Technical field
The utility model belongs to water meter measurement field, is specifically related to a kind of water meter device.
Background technology
Small-bore mechanical water meter is broadly divided into dry-type meter and wet-type meter two major classes in industry at present.
Dry-type meter passes mode, the central gear progress Magnetic drive of impeller and counting mechanism, counting mechanism using impeller magnetic
It is whole to be isolated with tested water body, counting mechanism reading part can be kept permanent clear in this way, but due to being passed using impeller magnetic,
The phenomenon that rotating speed is very fast, and Magnetic drive is likely to occur de- magnetic trip stop in the process when water flow variation is excessive is to influence to measure.
Wet-type meter is that clear reading is kept to use liquid seal structure substantially at present, and the transparent character wheel window of fluid-tight, which uses, vacuumizes filling
Liquid mode, this mode, which is difficult to ensure in batch production inside fluid-tight character wheel window, is completely filled with embedding liquid, even if filling, by
In character wheel window construction be thumb wheel character wheel outside window, character wheel is in window, the character wheel axis connection for passing through character wheel forms by one, due to word
Wheel shaft has gap with character wheel window axis hole, even if sealing ring has been added to be sealed, but the embedding for also being difficult to ensure in it is used for a long time
Liquid is not lost in.The steam occurred when producing given birth to minute bubbles and excessive temperature differentials when embedding liquid is discontented in character wheel window all can shadow
Ring character wheel reading.
Such as application No. is 201520422445.9 utility model patent, to disclose a kind of magnetic strength for liquid-sealing water meter straight
Read apparatus, including the off-balancesheet unit that is set to unit in the table in watchcase and is set to outside watchcase；Unit includes coupling in table
Gear and magnet steel；Off-balancesheet unit includes off-balancesheet coupling wheel, magnet steel, transmission gear and character wheel counting device；Magnetic in table body
Steel is fixedly connected by magnetic coupling and with driving wheel simultaneously with the external magnet steel of table；The external coupling wheel of table is for following in table body
Coupling wheel rotates, and driving wheel is used for the motion transmission of the external coupling wheel of table to character wheel counting device, character wheel counting device
For to water consumption cumulative measurement and display.The horizontal spreading schematic diagram of its drive mechanism is shown in attached drawing 4, although the utility model
Avoid bubble, water quality impact photoelectric reading and envelope caused by counting device is arranged in water meter existing liquid blocking type water meter
Glue problem of aging, but the device is that character wheel counting device is arranged in table external unit, is had in its water meter body as shown in Figure 4
With the impeller 10 that flow rotates, impeller 10 drives Multi-stage transmission gear 11 to rotate, and then drives coupling in the table body equipped with magnet steel
The rotation of gear 14, the utility model be arranged in water meter body there are one equipped with magnet steel table body in coupling wheel 14, the table
Internal coupling wheel 14 drives the table for being also provided with magnet steel being arranged outside water meter body external by magnet principle of opposite sex attraction
Coupling wheel 13 rotates, and then realizes the counting of the character wheel counting device outside water meter body.But since the utility model uses
Be that two groups of coupling wheels of table inside and outside carry out Magnetic drive, therefore it is extraneous close if any strong magnetic, be just highly susceptible to interfere, can
The external coupling wheel 13 of table can occur and can not be synchronized with coupling wheel 14 in table body by strong magnetic influence to be rotated, to go out
Inaccurate phenomenon is now counted, causes to influence normally to measure.In addition, this design the original structure for changing water meter, ratio is changed
Larger, character wheel segment count protrudes outside water meter body, and has also needed to positioning shell as support to complete, and changes entire
The appearance of water meter.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of water meter device, it can accomplish that the metering of wet type table is accurate
