Abstract
The invention discloses an anti-freezing device for a water meter. The anti-freezing device comprises a box, a box cover which can move up and down along the box is arranged at the upper opening of the box, and a sealed space whose volume can be compressed is arranged in the space formed by the box and the box cover. Compared with the prior art, the anti-freezing device has the advantages that the anti-freezing device is arranged in a cavity communicated with the cavity of the water meter when being used; when water in the water meter freezes and expands outwardly, ice squeezes towards the box cover to squeeze the sealed space due to the freezing process of the water is slow, the volume of the squeezed sealed space is reduced to release sufficient space for the ice, and accordingly the shell of the water meter can be prevented from bursting; the shape and size of the original water meter cavity can be kept unchanged by the box and the box cover, the remeasuring and correcting of the water flow features of the water meter are not needed, and the measuring precision of the water meter is guaranteed.
Description
Technical field
The present invention relates to a kind of water meter field, refer specifically to a kind of running water in water meter and occur to prevent water during frost
The defroster for 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 the water generation frost in water meter, the ice cube meeting outward expansion in water meter, causes to water meter
Destroy, water meter can be led to when serious to burst, the life giving people brings great inconvenience, also bring unnecessary economic damage simultaneously
Lose, therefore, when there is frost in a water when in water meter of necessary research and development, the water meter that housing will not burst.
Content of the invention
The present invention is directed to deficiency of the prior art, there is provided a kind of running water in water meter occur during frost can in case
The defroster for 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-for water meter
Freeze device it is characterised in that:Including box body, at the upper opening of described box body, it is provided with the box that can move up and down along described box body
It is provided with, in the space that lid, described box body and described lid are constituted, the confined space that volume can be compressed.During using the present invention, will
The present invention is arranged in the cavity being connected with water gauge chamber body phase, when the water in water meter occurs frost outward expansion, due to it
Freezing process is a slow process, and ice cube can extrude thus extruding confined space to lid, the confined space being squeezed
Volume-diminished, the ice cube for expanding discharges enough spaces, thus reaching the consequence preventing water meter case explosion;And, this
The box body of invention water meter and lid can make the form and dimension of original water meter cavity keep constant, be not required to the current to water meter special
Property is remeasured and is corrected, and ensures the certainty of measurement of water meter.
Preferably, above-mentioned confined space is air bag.The air bag of this programme has that structure is simple, 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:In above-mentioned air bag, there are compressed gas
The air pressure in air bag is made to be more than or equal to the hydraulic pressure in water meter case.This programme can prevent under the fluctuation of hydraulic pressure, due to
The change of air bag volume and affect the performance error of water meter situation occur.
Improve further:The top edge of above-mentioned box body bends inwards formation kink, the edge of described lid have with
The limiting section mutually leaning below described kink is thus prevent described lid from departing from described 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 constitute water stream channel part so that the box body of water meter of the present invention and lid can make former
The form and dimension having water meter cavity keeps constant, is not required to the flow characteristics of water meter be remeasured and corrects, and protects
The certainty of measurement of card water meter.
The present invention compared with prior art, has the advantages that:During using the present invention, the present invention is arranged at and water
In the cavity that table cavity is connected, when the water in water meter occurs frost outward expansion, delay because its freezing process is one
Slow process, ice cube can extrude thus extruding confined space to lid, and the confined space volume being squeezed reduces, for expand
Ice cube discharges enough spaces, thus reaching the consequence preventing water meter case explosion;And, the box body of water meter of the present invention and box
Lid can make the form and dimension of original water meter cavity keep constant, is not required to the flow characteristics of water meter be remeasured and is rectified
Just, and ensure the certainty of measurement of water meter.
Brief description
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is that the embodiment of the present invention is arranged on structural representation before icing for the water in water meter.
Fig. 3 is that the embodiment of the present invention is arranged on structural representation after icing for the water in water meter.
Specific embodiment
With reference to specific embodiment, the present invention is described in further detail:A kind of defroster for water meter,
It is characterized in that:Including box body 1, at the upper opening of described box body 1, it is provided with the lid 2 that can move up and down along described box body 1,
It is provided with the confined space 3 that volume can be compressed, in the present embodiment, institute in the space of described box body 1 and described lid 2 composition
Stating confined space 3 is air bag, has compressed gas the air pressure in air bag is more than or equal in water meter case in described air bag
Hydraulic pressure.
The top edge of described box body 1 bends inwards and forms kink 11, and the edge of described lid 2 has and described bending
The limiting section 21 mutually leaning below portion 11 is thus prevent described lid 2 from departing from described box body 1.
The smooth interior surfaces transition of described lid 2 and water meter case makes the part of water stream channel.
When using the present invention, the cavity 4a of water meter case 4 is communicated with cavity 5, described cavity, and 5 are arranged at described water meter
The bottom of housing 4, the housing of the present invention is arranged in cavity 5.When the water in water meter occurs frost outward expansion, due to it
Freezing process is a slow process, and ice cube can extrude thus extruding confined space to lid, the confined space being squeezed
Volume-diminished, the ice cube for expanding discharges enough spaces, thus reaching the consequence preventing water meter case explosion.
