Problems solved by technology
[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 effects; gas meters in the prior art are generally equipped with built-in valves, and the built-in valve interface is generally set on the upper case, because when the interface is connected with the gas pipeline, it needs to be rotated or plugged in Fixed, therefore, it is easy to affect the firmness of the interface, and it is easy to cause the air inlet and outlet of the upper watch case to become larger, resulting in an unstable installation. The existing method is to install a reinforcing plate on the inner side of the upper watch case, and through the reinforcing plate. Fixed, but the reinforcing plate only serves as a limit function, and cannot fix the intake pipe and outlet pipe
