Natural gas meter housing built-in valve reinforcing plate

Abstract

The invention discloses a natural gas meter housing built-in valve reinforcing plate comprising a plate body; two sides of the plate body are provided with valve mount holes; the center of the plate body is provided with a transition plate embedded with the inner side of the upper housing; the valve mount hole on one side is integrated with a screw mount base; the screw mount base is fixedly mounted with an upper housing inner screw hole. The natural gas meter housing built-in valve reinforcing plate uses mount position embedment and screw fixation in installation to well fix a built-in valve; meanwhile, the inner side of an existing natural gas meter housing needs no improvement, and the natural gas meter housing built-in valve reinforcing plate can be fixed by existing built-in valve fixing holes.

Description

technical field [0001] The invention relates to a natural gas watch case assembly, in particular to a built-in valve reinforcement plate of a natural gas watch case, which belongs to the technical field of natural gas watch cases. Background technique [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 o...

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 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. The air inlet and outlet of the watch case are installed in conjunction with the built-in valve. During the process of installation and disassembly, the built-in valve is easy to loosen and damage the built-in valve.
