Abstract
The utility model provides an integrated type double-diaphragm-cavity gas meter diaphragm capsule which mainly comprises an upper diaphragm capsule body (1) and a lower diaphragm capsule body (2), an inward-concave upper diaphragm cavity (12) is designed in the upper diaphragm capsule body (1), the bottom and the side walls of the upper diaphragm cavity (12) are in transition through a curved surface (122), a buffer cavity (121) is further designed in the curved surface (122), the lower diaphragm capsule body (2) and the upper diaphragm capsule body (1) are structurally symmetric, and the upper diaphragm capsule body (1) and the lower diaphragm capsule body (2) are of an integrally-formed symmetrical integrated structure. According to the integrated type double-diaphragm-cavity gas meter diaphragm capsule, two integrally-formed diaphragm cavities are designed, the steady circulation of the gas is ensured, meanwhile, the gas capacity is increased, and the large-volume requirement is met.
Description
Technical field
The utility model relates to a kind of gas meter, flow meter parts, relates in particular to a kind of two films chamber integral fuel gas pellicle box.
Background technology
The gas meter, flow meter bellows of prior art, in order to increase combustion gas capacity, often very large by bellows design, and under actual use occasion, often require again the bellows can not be too large, in order to solve this contradiction, the utility model provides a kind of pair of film chamber integral fuel gas pellicle box, efficiently solves this technical matters.
Utility model content
The utility model provides a kind of pair of film chamber integral fuel gas pellicle box, and in order to realize foregoing invention object, the utility model has adopted following technological means:
A kind of two films chamber integral fuel gas pellicle box, comprise bellows (1) and lower bellows (2), in described upper bellows (1), be designed with the upper film chamber (12) of indent, bottom, upper film chamber (12) and sidewall are by curved surface (122) transition, curved surface (122) is also designed with cushion chamber (121), lower bellows (2) and upper bellows (1) structure full symmetric, upper bellows (1) and lower bellows (2) are one-time formed symmetrical expression one-piece construction
In order to make full use of spatial volume, described upper bellows (1) is also designed with a circle the brim of a hat (10), is provided with seal groove (101), for rubber seal ring is installed on the brim of a hat (10).
Further, be also designed with reference column (11) on described upper bellows (1), the quantity of reference column (11) is 12, is equidistant layout.
Further, described upper bellows (1) and lower bellows (2) are respectively arranged with 2 pilot holes (14), and amounting to quantity is 4.
The utility model has the advantage of:
1. film two chambeies, take full advantage of spatial volume, have increased combustion gas capacity, have met jumbo demand;
2. upper and lower bellows is arranged symmetrically, simple in structure clear, easy for installation.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is bellows structure schematic diagram on the utility model;
The title of parts shown in figure and mark: 1-upper bellows, 10-the brim of a hat, 101-seal groove, 11-reference column, 12-upper film chamber, 120-gas outlet chamber, 121-cushion chamber, 122-curved surface, 13-gas outlet, 14-pilot hole, 15-reading opening, 16-fuel gas inlet, 2-lower bellows.
Embodiment
As depicted in figs. 1 and 2, a kind of two films of the utility model chamber integral fuel gas pellicle box, it comprises bellows (1) and lower bellows (2), upper bellows (2) and lower bellows (1) structure full symmetric, and upper bellows (1) and lower bellows (2) they are one-time formed symmetrical expression one-piece construction.
Upper and lower film chamber is all concave inward structure, and bottom, upper film chamber (12) and sidewall are by curved surface (122) transition, and curved surface (122) is also designed with cushion chamber (121), and cushion chamber (121) is mainly in order to make full use of spatial volume.
Upper and lower film chamber is designed with respectively reading opening (15), for reading element is installed, to read gas consumption value.
Following examples, only above bellows (1) is example explanation, lower bellows (2) principle of work is identical.
Combustion gas enters film chamber through fuel gas inlet (16), under the effect of curved surface (122) and cushion chamber (121), ensure the steady circulation of combustion gas, after combustion gas is accumulated in upper film chamber (12), can discharge through gas outlet chamber (120), gas outlet chamber (120) communicate with gas outlet (13).
Claims (4)
1. two films chamber integral fuel gas pellicle box, it is characterized in that: comprise bellows (1) and lower bellows (2), in described upper bellows (1), be designed with the upper film chamber (12) of indent, bottom, upper film chamber (12) and sidewall are by curved surface (122) transition, curved surface (122) is also designed with cushion chamber (121), lower bellows (2) and upper bellows (1) structural symmetry, upper bellows (1) and lower bellows (2) are one-time formed symmetrical expression one-piece construction.
2. the two films of one according to claim 1 chamber integral fuel gas pellicle box, is characterized in that: described upper bellows (1) is also designed with a circle the brim of a hat (10), is provided with seal groove (101), for rubber seal ring is installed on the brim of a hat (10).
