Abstract
The invention discloses an anti-freeze water meter which includes a water meter housing having a cavity body and a water meter assembly which is arranged inside the water meter housing. The water meter is characterized in that the cavity body is in communication with a cavity which has an enclosed space therein. The enclosed space has a compressible volume. Compared with prior art, when the water meter is in usage, and when water inside the water meter freezes and expands outwardly, since icing is a slow process, an ice cube extrudes the enclosed space, the volume of the extruded enclosed space shrinks, which release sufficient space for the expanded ice cube, so that explosion of the housing of the water meter is avoided. In addition, according to the invention, the enclosed space does not change the shape and size of the original cavity body of the water meter, and the water meter does not need to re-measure or correct the features of water flow of the water meter, and the water meter can guarantee measuring precision of the water meter.
Description
Technical field
The present invention relates to a kind of water meter field, refer specifically to a kind of tap water in water meter and occur to be possible to prevent water during frost
The water meter of table explosion.
Background technology
Water meter has been commonly used in the middle of the life of people, but when winter, due to the very fast decline of temperature, due to
The proportion of ice is less than the proportion of water, when there is frost in the water in water meter, the ice cube meeting outward expansion in water meter, causes water meter
Destroy, water meter time serious, can be caused to burst, bring great inconvenience to the life of people, also bring unnecessary economic damage simultaneously
Losing, therefore, necessary research and development are a when the water in water meter occurs frost, the water meter that housing will not burst.
Summary of the invention
The present invention is directed to deficiency of the prior art, it is provided that when there is frost in a kind of tap water in water meter can in case
The Anti-freezing water meter of sealing table explosion.
In order to solve above-mentioned technical problem, the present invention is addressed by following technical proposals: a kind of Anti-freezing water meter, including
The water meter case with cavity and the water meter assembly being arranged in described water meter case, it is characterised in that: described cavity connects
There is cavity, there is in described cavity the confined space that volume can compress.When using the present invention, when the water in water meter freezes
And during outward expansion, owing to its freezing process is a process slowly, ice cube can extrude to confined space, and be squeezed is close
Close spatial volume to reduce, discharge enough spaces for the ice cube expanded, thus reach the consequence preventing water meter case from bursting;And
And, the confined space of the present invention will not change the form and dimension of original water meter cavity, is not required to the flow characteristics to water meter and carries out
Remeasure and correct, and ensure the certainty of measurement of water meter.
As preferably, above-mentioned cavity is arranged at the bottom of described water meter case.Due to the moisture storage capacity bottom water meter relatively
Many, therefore, the water at this occurs to expand more seriously during frost, is arranged at by cavity and can obtain superior technique effect herein
Really.Certainly, except this programme, cavity may also be disposed on other peripheries of water meter cavity, and can also arrange 2 or two with
On.
As preferably, above-mentioned confined space is air bag, and described air bag is placed in described cavity.The air bag of this programme has knot
Structure is simple, the advantage that compression stroke is big.Meanwhile, except the air bag of this programme, it is also possible to take such as air cylinder structure or spring to tie
Other compressible structures such as structure.
In order to obtain superior technique effect, further technical measures also include: have compressed gas in above-mentioned air bag
Make the air pressure in air bag more than or equal to the hydraulic pressure in described water meter case.This programme is possible to prevent under the fluctuation of hydraulic pressure,
The situation affecting the performance error of water meter due to the change of air bag volume occurs.
Further improve and include: in above-mentioned cavity, be provided with air bag box, the shape of described air bag box and described cavity
Mating shapes, be provided with the airbag cover that can move up and down along described air bag box at the upper opening of described air bag box, described
Air bag is arranged in the space of described air bag box and described airbag cover composition.Air bag box arrange can more preferable fixation balloon,
And air bag can be made when being extruded to deform more specification.
Improve further: the edge, top of above-mentioned air bag box bends inwards formation kink, the edge tool of described airbag cover
Have with described kink below the limiting section that leans mutually thus prevent described airbag cover from departing from described air bag box.
In order to obtain superior technique effect, above-mentioned airbag cover is allowed to into the smooth interior surfaces transition of described water meter case
Ingredient for water stream channel.Airbag cover constitutes the ingredient of water stream channel so that the confined space of water meter of the present invention is not
The form and dimension of original water meter cavity can be changed, be not required to the flow characteristics of water meter be remeasured and corrects, and protect
The certainty of measurement of card water meter.
The present invention compared with prior art, have the advantages that use the present invention time, when the water generation ice in water meter
Freezing and during outward expansion, owing to its freezing process is a process slowly, ice cube can extrude to confined space, be squeezed
Confined space volume reduces, and discharges enough spaces for the ice cube expanded, thus reaches the consequence preventing water meter case from bursting;
And, the confined space of the present invention will not change the form and dimension of original water meter cavity, is not required to enter the flow characteristics of water meter
Row remeasures and corrects, and ensures the certainty of measurement of water meter.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention water structural representation before icing.
Fig. 2 is embodiment of the present invention water structural representation after icing.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is described in further detail: a kind of Anti-freezing water meter, including having chamber
The water meter case 1 of body 1a and be arranged at the water meter assembly in described water meter case 1, it is characterised in that: described cavity 1a connects
Having cavity 2, described cavity 2 to be arranged at the bottom of described water meter case 1, have in described cavity 2 that volume can compress is airtight
Space 3, in the present embodiment, described confined space 3 is air bag, and described air bag is placed in described cavity 2.
Having compressed gas in described air bag makes the air pressure in air bag more than or equal to the water in described water meter case 1
Pressure, so that air bag will not cause the change of the volume size of air bag due to variation in water pressure after installing to water meter.
The mating shapes of air bag box 4, the shape of described air bag box 4 and described cavity 2, institute it is provided with in described cavity 2
Stating and be provided with the airbag cover 5 that can move up and down along described air bag box 4 at the upper opening of air bag box 4, described air bag is arranged at institute
