Abstract
The utility model discloses a kind of Anti-freezing water meter, including water meter case with cavity and the water meter component that is arranged in the water meter case, it is characterised in that：The cavity is communicated with the confined space that can be compressed with volume in cavity, the cavity.Compared with prior art, during using the utility model, when there is frost and outwards expand in the water in water meter, because its freezing process is a slow process, ice cube can be extruded to confined space, the confined space volume being squeezed reduces, for the ice cube of expansion discharges enough spaces, so as to reach the consequence for preventing water meter case from bursting；And, confined space of the present utility model will not change the form and dimension of original water meter cavity, be not required to that the flow characteristics of water meter is remeasured and corrected, and ensure the certainty of measurement of water meter.
Description
Technical field
The utility model is related to a kind of water meter field, refer specifically to when a kind of running water in water meter is freezed can in case
The water meter of sealing table explosion.
Background technology
Water meter has been commonly used in the middle of the life of people, but in winter, due to the very fast decline of temperature, due to
Less than the proportion of water, when the water in water meter is freezed, the ice cube in water meter can outwards be expanded the proportion of ice, and water meter is caused
Destruction, can cause water meter to burst when serious, the life for giving people brings great inconvenience, while also bringing unnecessary economic damage
Lose, therefore, when a water when in water meter of necessary research and development is freezed, the water meter that housing will not burst.
The content of the invention
The utility model is directed to deficiency of the prior art, there is provided a kind of running water in water meter can when freezing
With the Anti-freezing water meter for preventing water table from bursting.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals：A kind of Anti-freezing water meter,
Including the water meter case with cavity and the water meter component being arranged in the water meter case, it is characterised in that：The cavity
It is communicated with the confined space that can be compressed with volume in cavity, the cavity.During using the utility model, when the water in water meter
When generation is freezed and outwards expanded, because its freezing process is a slow process, ice cube can be extruded to confined space, is subject to
The confined space volume of extruding reduces, and for the ice cube of expansion discharges enough spaces, prevents water meter case from bursting so as to reach
Consequence；And, confined space of the present utility model will not change the form and dimension of original water meter cavity, be not required to water meter
Flow characteristics is remeasured and corrected, and ensures the certainty of measurement of water meter.
Preferably, above-mentioned cavity is arranged at the bottom of the water meter case.Due to water meter bottom moisture storage capacity relatively
It is many, therefore, expansion is more serious when the water at this is freezed, and cavity is arranged at and can obtain herein superior technique effect
Really.Certainly, except this programme, cavity may also be disposed on other peripheries of water meter cavity, and can also set 2 or two with
On.
Preferably, above-mentioned confined space is air bag, the air bag is placed in the cavity.The air bag of this programme has knot
Structure is simple, the big advantage of compression stroke.Meanwhile, except the air bag of this programme, may also take on such as air cylinder structure or spring knot
Other compressible structures such as structure.
In order to obtain superior technique effect, further technical measures also include：There are compressed gas in above-mentioned air bag
So that the air pressure in air bag is more than or equal to the hydraulic pressure in the water meter case.This programme can be prevented under the fluctuation of hydraulic pressure,
The situation of the performance error of water meter is influenceed to occur due to the change of air bag volume.
In order to obtain superior technique effect, above-mentioned lid makes current with the smooth interior surfaces transition of water meter case
The part of passage.Lid constitutes the part of water stream channel so that the box body and lid of the utility model water meter can be with
The form and dimension of original water meter cavity is kept constant, be not required to that the flow characteristics of water meter is remeasured and corrected, and
And ensure the certainty of measurement of water meter.
Further improving includes：Air bag box, shape and the cavity of the air bag box are provided with above-mentioned cavity
Shape match, the airbag cover that can be moved up and down along the air bag box is provided with the upper opening of the air bag box, it is described
Air bag is arranged in the space that the air bag box and the airbag cover are constituted.The setting of air bag box can more preferable fixation balloon,
And air bag can be made to deform more specification when being extruded.
Further improve：The top edge of above-mentioned air bag box bends inwards to form kink, the edge tool of the airbag cover
There is the limiting section mutually leaned with kink lower section so as to prevent the airbag cover from departing from from the air bag box.
In order to obtain superior technique effect, above-mentioned airbag cover is allowed into the smooth interior surfaces transition of the water meter case
It is the part of water stream channel.Airbag cover constitutes the part of water stream channel so that the confined air of the utility model water meter
Between will not change the form and dimension of original water meter cavity, be not required to that the flow characteristics of water meter is remeasured and corrected, and
And ensure the certainty of measurement of water meter.
The utility model compared with prior art, has the advantages that：During using the utility model, when in water meter
When water occurs frost and outwards expands, because its freezing process is a slow process, ice cube can be extruded to confined space, received
Confined space volume to extruding reduces, and for the ice cube of expansion discharges enough spaces, prevents water meter case quick-fried so as to reach
The consequence split；And, confined space of the present utility model will not change the form and dimension of original water meter cavity, be not required to water meter
Flow characteristics remeasured and corrected, and ensure the certainty of measurement of water meter.

Fig. 2 is structural representation of the utility model embodiment water after icing.
Specific embodiment
The utility model is described in further detail with reference to specific embodiment：A kind of Anti-freezing water meter, including tool
The water meter component for having the water meter case 1 of cavity 1a and being arranged in the water meter case 1, it is characterised in that：The cavity 1a
Cavity 2 is communicated with, the cavity 2 is arranged at what can be compressed with volume in the bottom of the water meter case 1, the cavity 2
Confined space 3, in the present embodiment, the confined space 3 is air bag, and the air bag is placed in the cavity 2.
Cause the air pressure in air bag more than or equal to the water in the water meter case 1 with compressed gas in the air bag
Pressure so that after air bag is attached in water meter will not due to variation in water pressure cause air bag volume size change.
Air bag box 4 is provided with the cavity 2, shape and the shape of the cavity 2 of the air bag box 4 match, institute
The airbag cover 5 that can be moved up and down along the air bag box 4 is provided with the upper opening for stating air bag box 4, the air bag is arranged at institute
State in the space that air bag box 4 and the airbag cover 5 are constituted.
The top edge of the air bag box 4 bends inwards to form kink 41, the edge of the airbag cover 5 have with it is described
The limiting section 51 that the lower section of kink 41 mutually leans departs from so as to prevent the airbag cover 5 from the air bag box 4.
The airbag cover 5 makes the part of water stream channel with the smooth interior surfaces transition of the water meter case 1.
