Description
Technical field
This utility model relates to a kind of water meter, particularly relates to a kind of Anti-inversion water meter.
Background technology
Water users major part uses independent water meter measurement, and expense is by user's paying with water record according to water meter, water
Can table correctly record the water usage amount that user is actual, is related to the benefits of different parties such as user, management unit, enterprise.Present
Most water meters are when the water inlet of water meter and outlet are reversely installed, and the continuous data of water meter can reduce on the contrary with the outflow of water,
Make water meter can not record the actual used water amount of user truly, make user, management unit, each self-recording water number of enterprise according to going out
Existing larger difference, thus produces contradiction and economic dispute.
In order to stop water meter upside-down mounting, people also come up with some ways, such as: Patent No. 201320504803.1 disclosure
: Anti-inversion mechanism is made up of drainage box, water strainer, single current valve block, the threaded guide post in top, spring, nut tabletting,
Single current valve block is fitted on water strainer by being positioned at the threaded guide post in top at the water strainer center in drainage cassette bottom portion, spring
Being sleeved on the threaded guide post in top, nut tabletting is installed on the threaded guide post in top by center nut.Application
Number be 201520379103.3 patent disclose: described Anti-inversion device includes interior outlet, spheroid, upper block and lower block
Block, described upper block is welded on outlet on inwall, described lower block block welding under outlet on inwall, and with interior water outlet
Mouth is corresponding, and described spheroid is arranged between block and lower block.From the point of view of their disclosure, it has the disadvantage that
Flipped device is complex, for manufacturer, it is necessary to original production equipment is carried out bigger improvement, production cost
Of a relatively high.Also have partial monopoly document be disclosed that the water inlet pipe of water meter and the bore of outlet pipe are arranged to different big
Little.So the bore of its water inlet pipe installed and outlet pipe must be inconsistent, but the bore of the household water pipe of China is all consistent
, so this makes troubles to installation.
Utility model content
The purpose of this utility model is for the problems referred to above, it is provided that a kind of easy for installation, the Anti-inversion water of simple in construction
Table.
This utility model be the technical scheme is that a kind of Anti-inversion water meter, including: watermeter shell, water meter cover and water
Watch core, described watermeter shell upper periphery is provided with external screw thread, and top is provided with for by opening disposed within for water meter core；Described water
Watch glasses inwall is formed around the female thread matched with the external screw thread of watermeter shell upper periphery；Described water meter core depends on from top to bottom
Secondary it is: character wheel table, panel, gear assembly, impeller assembly, filter assemblies, described impeller assembly includes impeller box and impeller；Described
Filter assemblies is made up of filter cartridge and piston sheet, and described piston sheet is arranged in filter cartridge, and middle bottom filter cartridge is groove type
Drainage screen, the filtration network interface periphery of filter cartridge bottom interior surface has been evenly arranged 2 to 5 leads, the surrounding of piston sheet
Being provided with the breach coordinated with lead, the bottom of described impeller box props up the top of lead, so that piston sheet has well
One-way conduction function.
Described piston sheet is a plastic sheet, and centre is provided with a groove, is provided with Counter weight metal pad in groove.
Described gear assembly includes gearcase and gear train, and gear train is positioned at gearcase side, and opposite side is enumerator,
Described panel is one-body molded with enumerator and is sealed by gearcase mouth, and the part below water meter core upper panel all stretches into
In watermeter shell, upper panel surrounding is shelved on the opening of watermeter shell, makes character wheel table completely isolated with water, described character wheel table
On be provided with sheet glass, described water meter cover cover sheet glass surrounding and by arrange screw thread be connected with watermeter shell.
It is provided with multiple aperture, it is simple to water after getting rid of water meter verification or checking bottom the gearcase of described water meter gear assembly
The water of residual in table.
When opening running water switch, Anti-inversion water meter is intake, and water backs down entrance filter cartridge through filter screen piston sheet, then flows into
Impeller box, after closing running water switch, piston sheet sinks to seal bottom filter cartridge and by filter screen because of the gravity of self, if falling
Dress water meter, water will be unable to flow into, from impeller box, the filter screen blocked by piston sheet and flow out water meter, thus plays the effect of Anti-inversion.
The utility model has the advantages that: 1, simple in construction, input cost is low, only need to install additional in the filter cartridge of original water meter
Several diversion columns and a piston sheet；2, gearcase mouth is sealed by panel, makes character wheel table completely isolated with water, serves very
Good antifreezing effect.
