Abstract
The utility model discloses a kind of defroster for water meter, including box body, the lid that can be moved up and down along the box body is provided with the upper opening of the box body, the confined space that volume can be compressed is provided with the space that the box body and the lid are constituted.Compared with prior art, during using the utility model, the utility model is arranged in the cavity connected with water gauge chamber body phase, 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 to lid extruding so as to extrude confined space, and 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, the box body and lid of the utility model water meter can make the form and dimension of original water meter cavity keep constant, 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 defroster for 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 defroster for 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：One kind is used for water meter
Defroster, it is characterised in that：Including box body, being provided with the upper opening of the box body can move up and down along the box body
Lid, be provided with the confined space that volume can be compressed in the space that the box body and the lid are constituted.Using this practicality
When new, the utility model is arranged in the cavity connected with water gauge chamber body phase, when the water in water meter occurs frost simultaneously outwards
During expansion, because its freezing process is a slow process, ice cube can be to lid extruding so as to extrude confined space, by squeezing
The confined space volume of pressure reduces, and for the ice cube of expansion discharges enough spaces, prevents what water meter case from bursting so as to reach
Consequence；And, the box body and lid of the utility model water meter can make the form and dimension of original water meter cavity keep constant, no
The flow characteristics of water meter need to be remeasured and corrected, and be ensured the certainty of measurement of water meter.
Preferably, above-mentioned confined space is air bag.The air bag of this programme has a simple structure, big excellent of compression stroke
Point.Meanwhile, except the air bag of this programme, may also take on other compressible structures such as such as air cylinder structure or spring 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 water meter case.This programme can be prevented under the fluctuation of hydraulic pressure, due to
The change of air bag volume and influence the situation of the performance error of water meter to occur.
Further improve：The top edge of above-mentioned box body bends inwards to form kink, the edge of the lid have with
The limiting section that the kink lower section mutually leans is so as to prevent the lid from departing from from the box body.
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.
The utility model compared with prior art, has the advantages that：It is during using the utility model, this practicality is new
Type is arranged in the cavity connected with water gauge chamber body phase, when the water in water meter occurs frost and outwards expands, due to its icing
Process is a slow process, and ice cube can be to lid extruding so as to extrude confined space, the confined space volume being squeezed
Reduce, for the ice cube of expansion discharges enough spaces, so as to reach the consequence for preventing water meter case from bursting；And, this practicality
The box body and lid of new water meter can make the form and dimension of original water meter cavity keep constant, be not required to special to the current of water meter
Property is remeasured and corrected, and ensures the certainty of measurement of water meter.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is that the utility model embodiment is arranged on structural representation of the water before icing in water meter.
Fig. 3 is that the utility model embodiment is arranged on structural representation of the water after icing in water meter.
Specific embodiment
The utility model is described in further detail with reference to specific embodiment：A kind of antifreeze dress for water meter
Put, it is characterised in that：Including box body 1, the box that can be moved up and down along the box body 1 is provided with the upper opening of the box body 1
The confined space 3 that volume can be compressed is provided with the space that lid 2, the box body 1 and the lid 2 are constituted, in the present embodiment
In, the confined space 3 is air bag, causes that the air pressure in air bag is more than or equal to shell of water flowmeter with compressed gas in the air bag
Internal hydraulic pressure.
The top edge of the box body 1 bends inwards to form kink 11, and the edge of the lid 2 has and the bending
The limiting section 21 that the lower section of portion 11 mutually leans departs from so as to prevent the lid 2 from the box body 1.
The lid 2 makes the part of water stream channel with the smooth interior surfaces transition of water meter case.
When using the utility model, the cavity 4a of water meter case 4 is communicated with cavity 5, and the cavity 5 is arranged at the water
The bottom of watch shell 4, box body of the present utility model is arranged in cavity 5.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 to lid extruding so as to extrude confined space, and what is be squeezed is close
Spatial volume diminution is closed, for the ice cube of expansion discharges enough spaces, so as to reach the consequence for preventing water meter case from bursting.
