Abstract
The utility model discloses an aluminum alloy water meter shell, which comprises an aluminum alloy shell body. The internal surface of the shell body is coated with a protective layer with smooth surface and strong adhesive force. Compared with the prior art, the protective layer coated on the internal surface of the shell body can effectively prevent the aluminum alloy shell body from contacting with tap water directly, so that the oxidation of the aluminum alloy shell body is avoided and the service life of the aluminum alloy water meter shell is greatly prolonged. Furthermore, the protective layer does not generate reaction with the tap water, so that the secondary pollution to the water quality by the aluminum alloy water meter shell can also be avoided.
Description
Technical field
The utility model relates to a kind of aluminum alloy water meter shell.
Background technology
In the prior art, water meter can be made by cast iron usually, but because in long-term use, cast iron is owing to contact with tap water for a long time, and cast iron water meter shell gets rusty easily, and can produce serious secondary pollution and faces and be eliminated water quality.In order to improve this situation, it is found that aluminium alloy is good equivalent material, aluminium alloy is difficult for getting rusty, less to water pollution, it is a kind of novel by diecasting and pressure casting method to be as application number that 92224909.1 Chinese utility model patent discloses, the small-bore tap water water meter watchcase made from aluminum alloy materials.The said novel small diameter watermeter case made of this utility model is by watch shell, reaches the nut that is connected with the watch shell import and export with the watch shell watchcase cover that is connected suitable for reading and forms.Be characterized in that the head on angle α of wall of every bus of the housing water inlet inner chamber first half and water inlet inner chamber is the obtuse angle.
But the aluminum alloy water meter shell with the long-term contact process of tap water in can produce a kind of anode oxide film, and this anode oxide film becomes vesicular under microcosmic, and because the anode oxide film porous, so fouling easily, pickup, and can separate out whiteness in use for some time, antiseptic effect is also undesirable, and causes serviceable life shorter.
Summary of the invention
The utility model is at deficiency of the prior art, provides a kind of simple in structure, use to the water quality non-secondary pollution, the aluminum alloy water meter shell of long service life.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of aluminum alloy water meter shell comprises Al-alloy casing, is coated with the high protective layer of smooth surface and adhesion on the inside surface of housing.The utility model can prevent effectively that at the protective layer of the inside surface coating of housing Al-alloy casing from contacting with the direct of tap water, thereby has avoided Al-alloy casing to be subjected to oxidation, thereby has prolonged serviceable life of the present utility model greatly; Secondly, because protective layer and tap water can not produce reaction, therefore, also avoided the utility model that water quality is produced secondary pollution; Once more, because the protective layer smooth surface, so be not easy fouling, pickup.
In order to obtain better technique effect, further technical measures also comprise:
The inside surface of above-mentioned housing is the horniness anode oxide film after hard anodizing is handled.Horniness anode oxide film at first has further safeguard function to Al-alloy casing, and, because the characteristic of horniness anode oxide film porous can make protective layer better be coated on the inside surface of housing, improve adhesion with organic coating.
Because in use, the junction of Al-alloy casing and running water pipe also is vulnerable to the influence of tap water, for this reason, further improve: the water inlet of above-mentioned Al-alloy casing and the junction of water delivering orifice have the horniness anode oxide film after hard anodizing is handled.
One of preferred scheme: above-mentioned protective layer is an enamel layer.
Two of preferred scheme: above-mentioned protective layer is an adamantine layer.
Three of preferred scheme: above-mentioned protective layer is a Teflon.
Four of preferred scheme: above-mentioned protective layer is a powder coating.
Preferably, last powder coating is epoxies powder coating or polyester powder coating.
The utility model compared with prior art has following beneficial effect:
1) protective layer of the inside surface of Al-alloy casing coating can prevent effectively that Al-alloy casing from contacting with the direct of tap water, thereby has avoided Al-alloy casing to be subjected to oxidation, thereby has prolonged serviceable life of the present utility model greatly;
2) because protective layer and tap water can not produce reaction, therefore, also avoided the utility model that water quality is produced secondary pollution.
3) owing to the protective layer smooth surface, so be not easy fouling, pickup.
