Background technology
The most common water meter, mostly is wet-type meter, and its counting assembly is immersed in the water work, and its watch crystal bears hydraulic pressure, and sensor is gear-linked with the transmission of enumerator.Autumn and winter season especially north cold area, be immersed in water due to the plastics parts in water meter after mercury dropped, on the one hand, volumetric expansion after water freezing when temperature is too low, cause dial plate glass to burst, cause the damage of water meter.The opposing party, water meter is required for when dispatching from the factory verifying water meter or checking, and after this process, residual water is had in making water meter, produce so having pressure during installing and using in water meter, when meeting low temperature, the water freezing that water meter can bear expands the pressure brought can be less, it is easier to causes water meter bursting by freezing.
Utility model content
The purpose of this utility model is for the problem of bursting by freezing in the environment of effectively overcoming existing water meter temperature being on the low side in autumn and winter season.
Anti-freezing water meter of the present utility model, including: watermeter shell, water meter cover and water meter 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 meter cover inwall is formed around the female thread matched with the external screw thread of watermeter shell upper periphery；Described water meter watch core is followed successively by from top to bottom: character wheel table, panel, gear assembly, impeller assembly, filter assemblies, described gear assembly includes gearcase and gear train, gear train is positioned at gearcase side, opposite side is enumerator, described panel is one-body molded with enumerator and is sealed by gearcase mouth, and the part below water meter watch core upper panel all stretches in watermeter shell, upper panel surrounding is shelved on the opening of watermeter shell, make character wheel table completely isolated with water, it is provided with sheet glass on described character wheel table, described water meter cover is covered sheet glass surrounding and is connected with watermeter shell by the screw thread arranged.
In order to antifreezing effect is more preferable, bottom the gearcase of described water meter gear assembly, it is provided with multiple aperture, it is simple to the water of residual in water meter after getting rid of water meter verification or checking.
In order to antifreezing effect is more preferable, described sheet glass be its thickness of safety glass sheet be 8mm.
In order to antifreezing effect is more preferable, between described sheet glass and described character wheel table, it is provided with sealing ring.
In order to antifreezing effect is more preferable, between described upper panel and described watermeter shell opening, it is provided with sealing ring.
In order to antifreezing effect is more preferable, the character wheel part of described enumerator uses makrolon material molding, and big font size wheel anti-icing fluid is encapsulated in confined space.
In order to antifreezing effect is more preferable, above described sheet glass, it is coated with one layer of heat preservation material.
In order to this Anti-freezing water meter performance is more preferable, the piston sheet with one-way conduction function is set in described filter assemblies, makes tap water to flow in one direction, countercurrently can not can prevent user's upside-down mounting water meter.
The utility model has the advantages that: 1, good freezing protection effect, 2, prevent water smoke and the generation of incrustation scale in water meter, during reading, definition is higher.Because, on the one hand: the character wheel part of enumerator of the present utility model uses makrolon material molding, big font size wheel anti-icing fluid is encapsulated in confined space, and panel is by completely isolated with character wheel table for water, serve the effect of antifreeze, water-mist-proof and incrustation scale, on the other hand, bottom the gearcase of water meter gear assembly, be provided with multiple aperture, the water of residual in water meter after eliminating water meter verification or checking, this further improves antifreezing effect.3, Anti-inversion.Owing to arranging the piston sheet with one-way conduction function in filter assemblies, make tap water to flow in one direction, countercurrently can not serve the effect of Anti-inversion.
