[0002] Existing gas meter watch case mainly has two kinds of materials namely iron shell and aluminum shell, and shape has two kinds of big shell watch and small shell watch; Small aluminum shell 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 the sealing and metering effect; the large watch case is generally fixed by a ring of bolts through the upper watch case and the lower watch case, and the upper watch case and the lower watch case in the prior art are only connected by bolts Ordinary fixed, the connection between the two is not tight enough, it is easy to cause the inside of the case to be corroded by water and impurities

The invention discloses a fixing part for a natural gas meter case. The part comprises an upper meter case and a lower meter case as well as a fixing strip arranged on the upper meter case and the lower meter case. The bottom of the upper meter case and the top of the lower meter case are provided with an upper extending ring and a lower extending ring, both of which are integrally formed. Multiple protrusions are pressed at the interval between the upper side of the upper extending ring and the lower side of the lower extending ring. The fixing strip is composed of a first semi-ring fixing strip and a second semi-ring fixing strip. The middle parts of the first semi-ring fixing strip and the second semi-ring fixing strip are fixedly installed. The fixing part for the natural gas meter case has following beneficial effects: by installing the fixing strips on the upper meter case and the outside of the lower meter case, transverse fixation is formed; then, the protrusions are nested with notches so that longitudinal installation is formed; the fixing strips are formed by assembly of the first semi-ring fixing strip and the second semi-ring fixing strip; and an installation process is simple and the part is convenient to use.
Description
technical field [0001] The invention relates to a natural gas watch case assembly, in particular to a natural gas watch case fixing part, 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 the sealing and metering effect; the large watch case is generally fixed by a ring of bol...
