Description

Technical Field

[0001] The utility model relates to the technical field of water meters, in particular to an antifreeze water meter cover. Background Art

[0002] A water meter is an instrument installed on a pipe to measure the flow of liquid flowing inside the pipe. Usually, the water meter is installed outdoors. In order to prevent freezing in winter, it is generally insulated. The specific method is to wrap the water meter with an insulation cover to prevent freezing. However, the insulation effect of the existing insulation cover is not ideal, and because the water meter is an irregular shape, there will be a large gap when the insulation cover is wrapped on the water meter, which is not conducive to insulation. Utility Model Content

[0003] The utility model aims to provide an antifreeze water meter cover in view of the problems existing in the background technology.

[0004] The technical solution of the utility model is: an antifreeze water meter cover, comprising a cover body wrapped around the water meter, the cover body is divided into a fiber layer and a fluff layer from top to bottom, there is a cavity between the fiber layer and the fluff layer, and the cover body also includes an air bag arranged in the cavity.

[0005] Preferably, the airbag is provided with an air delivery head, the fiber layer is provided with air holes, and the air holes are provided with sealing plugs.

[0006] Preferably, the connection between the fiber layer and the fluff layer is an elastic cloth layer, and zippers are provided on the fiber layer and the fluff layer.

[0007] Preferably, the casing body is wrapped with an outer protective layer, the casing body and the outer protective layer are both provided with observation ports, and a transparent film is installed in the observation port in the casing body.

[0008] Preferably, a plurality of groups of Velcro components are installed on both sides of the sleeve and the outer protective layer, and the Velcro components include Velcro hook surfaces and Velcro velvet surfaces.

[0009] Compared with the existing technology, the beneficial effects of the utility model are:

[0010] 1. By setting an air bag in the insulation cover, it is used that the gas has a large distance between molecules and a violent molecular movement, so it is difficult to form heat conduction. In addition, the gas has the characteristics of low specific heat, low density, and low thermal conductivity, so the thermal insulation performance of the gas is more obvious and has a heat preservation effect, so that the water meter cover has a better heat preservation and antifreeze effect, and the production cost is low, which is easy to promote.

[0011] 2. During specific use, the airbag is inflated. As the volume of the airbag expands, the downward-pressed fluff layer will fit tightly against the water surface, making the wrapping tighter and reducing the generation of gaps, thereby improving the thermal insulation effect.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] Refer to the attached Figure 1-3 The invention discloses an antifreeze water meter cover, comprising a cover body 1 wrapped around the outside of the water meter, wherein the cover body 1 is divided into a fiber layer 11 and a fluff layer 12 from top to bottom, and a cavity 14 is formed between the fiber layer 11 and the fluff layer 12. The cover body 1 also comprises an air bag 15 arranged in the cavity 14. By setting the air bag 15, the gas is difficult to form heat conduction due to the large distance between molecules and the violent molecular motion, and the gas has the characteristics of low specific heat, low density, low thermal conductivity, etc., so that the heat insulation performance of the gas is more obvious and the heat preservation effect is achieved, so that the heat preservation and antifreeze effect of the water meter cover is better, and the production cost is low, which is easy to promote.

[0018] In this embodiment, the airbag 15 is provided with an air delivery head 16, the fiber layer 11 is provided with an air hole 17, the air hole 17 is provided with a sealing plug 7, the connection between the fiber layer 11 and the fluff layer 12 is an elastic cloth layer 13, and the fiber layer 11 and the fluff layer 12 are provided with a zipper 8.

[0019] It should be noted that there are two ways to use the airbag 15. One is to inflate the airbag 15 in advance before the airbag 15 is installed in the cavity 14, and the other is to inflate the airbag 15 after it is installed in the cavity 14. The latter is specifically introduced in this embodiment. When in use, the airbag 15 is installed in the cavity 14, and the air supply head 16 is just located in the air hole 17. Then the sleeve 1 is wrapped around the outside of the water meter. When the sleeve 1 is fixed, air can be inflated into the airbag 15 through the air supply head 16. When inflated, as the volume of the airbag 15 expands, the downward-pressed fluff layer 12 will fit tightly against the water meter, making the wrapping tighter, thereby improving the thermal insulation effect. In specific use, after the airbag 15 is installed, the fiber layer 11 and the fluff layer 12 can be sealed by the zipper 8.

[0020] In this embodiment, the outer sheath 2 is wrapped around the casing 1, and both the casing 1 and the outer sheath 2 are provided with an observation port 3. A transparent film 4 is installed in the observation port 3 in the casing 1. Through such a setting, it is ensured that the meter can be read without removing the insulation cover. Both sides of the casing 1 and the outer sheath 2 are provided with multiple groups of Velcro components, and the Velcro components include a Velcro hook surface 5 and a Velcro velvet surface 6. Figure 1 and Figure 2 When the sleeve 1 is wrapped around the water meter, it is fixed by sticking the Velcro hook surface 5 to the Velcro velvet surface 6. It can be observed from the figure that the Velcro components are respectively arranged at the side and the waist, which will make the fixation more secure. After the sleeve 1 is installed, the outer protective layer 2 can be wrapped around the outside of the sleeve 1. The setting of the outer protective layer 2 can improve the effect of heat preservation and antifreeze. In this embodiment, the sleeve 1 wraps the water meter from top to bottom, and the outer protective layer 2 wraps the sleeve 1 from bottom to top, so that the connection of the sleeve 1 will be wrapped inside.
