Description

Gas meter with improved sealing structure.

The present invention relates to a gas meter which has an improved sealing structure, and more particularly, has an improved sealing structure to prevent separation of the upper and lower cases of the meter and the totalizer cover so that operation of the totalizer indicating the gas usage is impossible. The present invention relates to the provision of a gas meter.

The gas meter is installed in the place of business or house that is used for heating and cooking fuel by using city gas, etc., so that the total amount can be checked. The gas meter is usually equipped with a common metering device for measuring the amount of use inside the upper and lower cases. On the front of the upper case, a conventional totalizer is fixed, which displays the amount used.

On both sides of the upper case, an inlet connected to the supply pipe for supplying the gas to be used is integrally formed, and on the opposite side, an outlet for supplying the gas passed through the meter to the heating device or the cooking device is provided.

As the meter is installed on the wall inside the store or house, it adopts a method of checking and describing the amount of use by the user without a meter reading person, so some consumers dismantle the meter and operate the totalizer. This often happened.

In order to solve this problem, the present situation is to supply a sealed meter so that it is impossible to disassemble the meter.

As shown in FIG. 3, the seal of the conventional meter 6 is sealed at one position of the site where the upper and lower cases 1 and 2 are bolted together, and the upper case 1 and the totalizer 4 are sealed. ) Is a method of sealing (5) to one of the sites to be bound.

As described above, in the prior art, since sealing is performed at two places, a considerable delay occurs in assembling the meter, so that the overall assembly performance is reduced.

In particular, the fixing hole for attaching the meter to the bracket is formed on the back of the upper case, but because of the additional process of manually processing on the thick part formed integrally with the upper case, the assembly efficiency (workability) is improved. It will be degraded.

This is because the thick portion formed in the upper case is formed in the transverse direction and the separation of the mold is made in the longitudinal direction is not able to integrally form the fixing hole on the thick portion.

The present invention is to solve the problems as described above by fixing the seal for preventing the disassembly of the meter to the one place to fix the totalizer and the lower case is fixed between the upper and lower case upper bolting coupling It is aimed not only to disassemble the whole but also to improve the overall assembly.

Hereinafter, with reference to the accompanying drawings will be described the configuration and operation of the present invention for achieving the above object.

1 is a front view of a gas meter to which the technique of the present invention is applied, and FIG. 2 is a schematic cross-sectional view of an internal portion of FIG.

The meter 10 for checking gas consumption is provided in front of the upper and lower casings 12 and 13 and the upper and lower casings 12 and 13 that are fixed with mutual bolts 11 by receiving a conventional metering device therein. It is composed of an accumulator 14 which accommodates a normal accumulator and is fixed with a bolt 11.

The upper surface of the upper case 12 has an inlet port 15 for receiving a gas to be used to be connected to the gas inlet pipe and an outlet 16 for supplying the gas passed through the metering device to the heating and cooking device inside the house or business. It is a structure which has it integrally.

In the present invention, by disassembling the upper and lower cases 12 and 13 and the totalizer 14 of the meter 10 as described above, the seal 20 is fixed to only one place so that the totalizer 14 cannot be operated. The upper and lower cases 12 and 13 as well as the decomposition of the totalizer 14 is to be blocked at the source.

The configuration of the present invention for this purpose;

In order to fix the upper case 12 and the bolt 11, the thick portion 22 which further protrudes downwardly from the front and rear flanges 21 formed on the upper edge of the lower case 13 is integrally formed.

The fastening hole 25 is formed on the thick part 22 at the same position as the fixing hole 24 formed at the lower end of the flange 23 of the totalizer 14 so that the upper flange 23 of the totalizer 14 is an upper case. Fix it with (12).

The lower flange 23 of the totalizer 14 fixes the seal 20 together with the bolt 11 through the fastening hole 25 formed in the thick part 22 of the lower case 13.

The operation of the present invention as described above is a thickening unit 14 integrally formed on the flange 21 of the lower case 13 is fixed to the upper case 12 and the totalizer 14 to indicate the gas usage (bolt 11) 22) Since the seal 20 is fixed together while being fixed on the top, it is possible to prevent the separation of the totalizer 14 as well as the separation of the upper and lower cases 12 and 13 with a single seal.

In particular, the thick portion 22 formed on the flange 21 of the lower case 13 is formed in the same position in the front and lower, and the fastening hole 25 formed thereon is also formed at the same position, so that the fixed position of the totalizer 14 is fixed. This ease of course is made easy to install the meter 10 itself.

In addition, in consideration of the characteristics in which the mold for forming the lower case 13 is separated in the horizontal direction from the fastening hole 25 on the thick portion 22 formed integrally with the flange 21 of the lower case 13, the mold Since it is formed integrally in the molding process, there is an advantage that no additional process is required.

The present invention as described above, by fixing the seal for preventing the disassembly of the meter to one site of fixing the totalizer and the lower case which is fixed between the upper and the lower case to be bolted coupled to prevent the disassembly of the whole of the meter. It is possible to improve the assemblability.
