Rapidly-installed natural gas meter

Abstract

The invention discloses a rapidly-installed natural gas meter. The meter comprises an upper meter shell and further comprises a meter box and a meter cover. A square seat is pressed on the surface of the upper meter shell from the inside to the outside. An inner lead wire through hole and multiple blots are formed in the square seat. An outer lead wire through hole corresponding to the inner lead wire through hole is arranged on the meter box. Multiple jacks corresponding to the multiple bolts are arranged in the meter box. Inner installing lugs are arranged on two sides of the meter box. Two sides of the meter cover are provided with outer installing lugs matched with the inner installing lugs. The inner installing lugs and the outer installing lugs are fixed through screws. The square seat and the meter box are fixed by installing nuts on the blots. The rapidly-installed natural gas meter has following beneficial effects: installation and detachment are directly streamlined so that a gauging table is protected and installation and detachment time are reduced; production efficiency is raised; when there is something wrong with the meter box, the box can be independently replaced and usage cost is lower.

Description

technical field [0001] The invention relates to a natural gas watch case assembly, in particular to a quick-installed natural gas meter head, which belongs to the technical field of natural gas watch cases. Background technique [0002] Existing gas meter casing mainly has two kinds of materials namely iron casing and aluminum casing, and the shape has two kinds of big casing watch and small casing watch; Small aluminum casing shape, compact structure, beautiful appearance; The flow plate prevents the moisture and impurities in the coal gas from flowing directly to the slide valve system. At the same time, its large shell has the function of buffering the flow rate and containing the moisture and impurities in the artificial gas, so that the transmission parts such as the sealing layer of the air chamber and the slide valve are not affected. Corroded by water and impurities, so as to ensure sealing and metering effect; because the meter needs to be read frequently, it is gen...

[0002] Existing gas meter casing mainly has two kinds of materials namely iron casing and aluminum casing, and the shape has two kinds of big casing watch and small casing watch; Small aluminum casing shape, compact structure, beautiful appearance; The flow plate prevents the coal gas moisture and impurities from flowing directly to the slide valve system. At the same time, its large shell has the function of buffering the flow rate and containing the moisture and impurities in the artificial gas, so that the transmission parts such as the sealing layer of the air chamber and the slide valve do not Corroded by water and impurities, so as to ensure sealing and metering effect; because the meter needs to be read frequently, it is generally installed outside the casing. The casing of the meter in the prior art is generally a plastic structure that is easy to break. The groove for installing the meter is pressed on the case, the installation process is more complicated, and it is difficult to replace the material alone
