Abstract
The utility model relates to a protective cover for a water meter. The utility model comprises a cover cap and a cover body, wherein, the cover cap and the cover body are assembled by polypropylethylene foam and polypropylethylene plastic according to an inner layer and an outer layer. The protective cover for a watermeter, which is sealed and is arranged on the outside of the water meter, preserves heat for the water meter, prevents water meter glass rupturing, saves water resource, and simultaneously has the function of cleanness and beauty.
Description
The utility model relates to a kind of tap water water meter protective cover.
The present tap water water meter that uses, owing to be not incubated measure and the water meter shell is the cast iron casting goods, when temperature was reduced to below 0 ℃, the water in the water meter easily froze usually, and water freezing is volumetric expansion, causes certain pressure to water gage glass; Simultaneously, because the hydraulic pressure of tap water is generally 0.2-0.4Mpa, add because of temperature reduces to make water gage glass and water meter shell produce all reasons such as convergent force, therefore, in case when these force of compression sums surpass the holding capacity of water gage glass, just cause water gage glass to break, cause and leak, wasted water resource.
The purpose of this utility model provides a kind of water meter protection that can prevent that water gage glass from breaking and puts.
For achieving the above object, the solution that the utility model is taked is: increase protective cover in the water meter outside seal, this water meter protective cover comprises cover cap and cover body, and cover cap and cover body divide inside and outside layer to combine by poly-third vinyl foam, poly-third vinyl plastics.
Because water meter is sealed in the protective cover, and polystyrene foam and plastics all are insulation materials, and when temperature reduced, water meter can be incubated under certain condition, and water gage glass has been wasted water resource with regard to being unlikely to break.Simultaneously, protective cover is the effect of the attractive in appearance and cleaning of tool again, and cost is lower.
Fig. 1 is the utility model after removing the water meter lid, is installed in half sectional view on the water meter.
Fig. 2 is the sectional view that is used to install button of the present utility model.
See figures.1.and.2, two parts that the cover body of this water meter protective cover matches before and after dividing, and the skin of cover cap and cover body is polystyrene plastics 1, internal layer is a polystyrene foam 3.During installation, the front and rear part of water meter protective cover cover body closed up cover water meter shell 4, by hole 2 by button 7 fixing after, cover cover cap 5 and just water meter be sealed in the water meter protective cover.When temperature reduced, because water meter shell 4 is sealed in the water meter protective cover, water meter can be incubated under certain condition, just can prevent water freezing, reduces the convergent force of water gage glass 6 and water meter shell 4, reaches the purpose that prevents that water gage glass 6 from breaking.
In addition, the cover body of above-mentioned described water meter protective cover obviously also can be divided into two parts up and down, equally also can realize the purpose of this utility model.
Claims (2)
1, a kind of water meter protective cover with the water meter outside seal, is characterized in that this water meter protective cover comprises cover cap and cover body, and cover cap and cover body divide inside and outside layer to combine by poly-third vinyl foam and poly-third vinyl plastics.
2, water meter protective cover according to claim 1 is characterized in that the cover body of this water meter protective cover is divided into two parts, and two parts or be positioned at the front and back of water meter, or be positioned at water meter about.
