Abstract

PURPOSE: A protective cover of a gas metering device is provided to allow the gas metering device to be stably operated and to improve the quality of the gas metering device by forming the protective cover using foaming synthetic resin. CONSTITUTION: A protective cover(100) is formed at upper sides thereof with coupling holes(110) so as to allow an inlet valve(210) and an outlet valve of a gas metering device(200) to be installed therein. A window is formed at a front portion of the protective cover(100). The protective cover(100) is made of soft foaming synthetic resin(100a) including foaming urethane, rubber, silicon or synthetic resin. Since the protective cover(100) has superior flexibility, an additional part is not required when installing the protective cover(100) to a wall. The protective cover(100) has a thermal insulation characteristic and shock absorbing function, so the gas metering device(200) is stably operated in winter.

Description

Cover of a gas meter {Cover of a gas meter}

The present invention relates to a gas meter protection cover, and in particular, by forming a protective cover for protecting the gas meter from the outside by molding a material of foamed synthetic resin made of foam urethane, rubber, silicone, synthetic resin, etc., simplifying the structure The gas meter protection cover not only makes the operation easier but also reduces the production cost and gives the gas meter a thermal insulation effect that keeps the equipment running smoothly and improves the product's quality. will be.

In general, the gas meter indicating the actual usage of the gas is classified into wet and dry, the diaphragm gas meter is widely used as a double dry gas meter. Since the diaphragm type gas meter does not need to adjust the surface like a wet gas meter, there is little fear of freezing, and thus it is widely used for home or factory use.

These gas meters are essentially installed with a protective cover to protect from external impact or the surrounding environment. 1 and 2, the conventional protective cover configuration is briefly described, as shown in FIGS. 1 and 2, and a fastening end 12 having fastening holes 13 at right and left four positions so that the protective cover 10 can be installed and fixed on a wall during molding. ) Is formed and a fastening hole 16 is formed at the top so that the inlet side 14 and the outlet side 15 of the gas meter 11 can be inserted and coupled. 16 is formed.

Using the conventional protective cover 10 has the advantage that the intended purpose, that is, gas meter 11 can be protected from external impact or the surrounding environment, but the conventional protective cover 10 is made of a hard plastic material Therefore, in order to install the protective cover 10 formed of a hard plastic to the gas meter 11 has to be installed in a state that ensures a sufficient space for installation with a gas meter is usually large in size.

Therefore, as the means for fixing the protective cover 10 to the wall surface, the fastening ends 12 are mobilized in four places on the left and right side, which increases the number of parts and increases the production cost. .

In addition, since the insulating material is not made of a plastic material, the operation of the gas meter 11 is not made smoothly during the winter season, and it is easily broken even in a light shock, resulting in various problems of shortening the product life.

Therefore, the object of the present invention is devised in view of the conventional problems as described above, by molding a protective cover for protecting the gas meter from the outside by molding a foamed synthetic resin made of foam urethane, rubber, silicone, synthetic resin, etc., The gas is designed to simplify the structure, simplify installation, reduce production costs, and give the gas meter a thermal insulation effect that keeps the equipment running smoothly and improves product quality to extend product life. To provide a meter protective cover.

As a means for achieving the above object, the present invention is installed in a home or factory, etc. In the protective cover to cover the outside of the gas meter indicating the actual usage of the gas to protect the gas meter from the outside, select the protective cover and It is a basic feature of the technical configuration that the material is formed of foamed synthetic resin when molding the selected protective cover.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 3 is a front view showing a state in which the protective cover according to the present invention installed in the gas meter, Figure 4 is a side view showing a state in which the protective cover according to the present invention installed in the gas meter.

In the protective cover 100 of the present invention, the fastening hole 110 is formed at the upper left and right sides so that the inlet side 210 and the outlet side 220 of the gas meter 200 can be installed, and the viewing window 120 is formed at the front side. The basic context is the same as before.

However, the present invention is to enable more effective use of the protective cover 100, which is molded from a soft foamed synthetic resin (100a) material when forming the protective cover 100, as shown in Figures 3 and 4, when the top A well-known fastening hole 110 into which the inlet side 210 and the outlet side 220 of the gas meter 200 can be inserted and coupled to the left and right sides, and a well-known display window 120 through which the gas usage can be viewed from the outside. This is formed.

Here, the foamed synthetic resin (100a) is optionally used foamed urethane, rubber, silicone, synthetic resin.

Thus, the protective cover 100 is formed of a synthetic resin (100a) for the foam is relatively soft, so that it is possible to combine in a close contact with the gas meter 200 without forming a sufficient installation space when forming, accordingly conventional As such, the parts for installing the protective cover 100 on the wall is not necessary.

In addition, the protective cover 100 as described above has the effect of keeping warm / cold, shock absorption due to the characteristics of the material can be expected not only smooth operation of the gas meter during winter, but also not easily damaged from external impact.

As described above, according to the present invention, since the protective cover for protecting the gas meter from the outside is molded of a foamed synthetic resin material, the installation work of the protective cover can be easily performed, and the number of parts is significantly reduced, thereby reducing the production cost. It is effective.

In addition, the protective cover formed of foamed synthetic resin material gives the gas meter a function to prevent heat retention and moisture absorption, so that the gas meter operates smoothly and is not easily damaged by external shocks. This is the effect.

The present invention has been described above with reference to specific preferred embodiments, but the present invention is not limited to the above embodiments and various changes and modifications may be made by those skilled in the art without departing from the gist of the present invention. Make sure you can.
