Abstract
The utility model discloses a housing sealing assembly for a gas meter. The essential of the technical scheme of the utility model is as follows: the housing sealing assembly for the gas meter comprises an inner sealing ring, an outer sealing ring, an upper shell and a lower shell, wherein the upper shell comprises an upper shell body and an upper convex edge; the lower shell comprises a lower shell body and a lower convex edge; the inner sealing ring is located on the fitting surfaces of the upper convex edge and the lower convex edge; the upper convex edge and the lower convex edge are coated by the outer sealing ring; the inner sealing ring comprises two sealing parts and contact parts; a space between the two sealing parts is V-shaped; the contact parts are connected with the two sealing parts; the section of the inner sealing ring is Y-shaped. The housing sealing assembly for the gas meter, disclosed by the utility model, has the advantages of being capable of avoiding gas leakage, and relatively excellent in sealing effect.
Description
Technical field
The utility model relates to the gas meter, flow meter field, and more particularly, it relates to a kind of shell of gas meter seal assembly.
Background technology
Diaphragm gas meter mainly is comprised of critical pieces such as movement, indicating device, shell and count displays.Due to the singularity of combustion gas, in case reveal the life security that just jeopardizes numerous people, so the security of gas meter, flow meter is even more important.It is particularly important that the sealing of its housing seems, current Chinese utility model patent number 201220381964.1 shell of gas meter seal assemblies, comprise two O-ring seals, upper casing, lower casing, cushion rubber, cushion rubber is arranged on the lower casing edge, upper casing and lower casing laminating seal by seal, seal is " U " type, along the seal inside surface, groove is set, and the groove two ends respectively are provided with a salient point; Described upper casing, lower casing bottom all extends and limit and 2 through holes are respectively opened in both sides, and the position of through hole, shape are corresponding with salient point.The design of this hermetically-sealed construction is only an improvement to the exterior seal ring of shell, and little to the effect that prevents gas leakage, the effect of sealing is also not obvious.
The utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of gas leakage, more superior shell of gas meter seal assembly of sealing effectiveness stopped.
For achieving the above object, the utility model provides following technical scheme: a kind of shell of gas meter seal assembly, comprise inside and outside O-ring seal, upper casing, lower casing, upper casing comprises upper casing body and upper convex edge, lower casing comprises lower casing body and lower convex edge, inner seal ring is positioned at the surface of upper and lower convex edge laminating, external seal coats upper and lower convex edge, described inner seal ring comprises two sealings, contact site, between described two sealings, be " V " type, described contact site all is connected with two sealings, and described inner seal ring cross section is " Y " type.
By adopting technique scheme, described inner seal ring comprises two sealings, contact site, between described two sealings, be " V " type, described contact site all is connected with two sealings, described inner seal ring cross section is " Y " type, in the cavity that upper and lower shell forms, be full of combustion gas, when the combustion gas wish is revealed from the upper and lower shell surface of contact, the combustion gas meeting forms an acting force to two sealings of inner seal ring, make two sealing distortion play self-styled effect, stop gas leakage, sealing effectiveness is more superior.
The utility model further is set to: the angle between described two sealings is 120 degree.
By adopting technique scheme, by the angle between two sealings, be 120 degree, can improve the sealing effectiveness of inner seal ring.
The utility model further is set to: described inside and outside O-ring seal is that elastomeric material is made.
The utility model further is set to: described external seal is " U " type.
By adopting technique scheme, the exterior seal ring setting is to " U " type, simple in structure, easy for installation, gas meter, flow meter is formed to secondary seal.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model shell of gas meter seal assembly embodiment.
Embodiment
With reference to Fig. 1, the utility model shell of gas meter seal assembly embodiment is described further.
A kind of shell of gas meter seal assembly, comprise inner seal ring 1, exterior seal ring 2, upper casing 3, lower casing 4, upper casing 3 comprises upper casing body 31 and upper convex edge 32, lower casing 4 comprises lower casing body 41 and lower convex edge 42, inner seal ring 1 is positioned at upper and lower protruding 32,42 surfaces along laminating, external seal 2 coats upper and lower convex edge 32,42, described inner seal ring 1 comprises two sealings 11, contact site 12, between described two sealings 11, be " V " type, described contact site 12 all is connected with two sealings 11, and described inner seal ring 1 cross section is " Y " type.
By adopting technique scheme, described inner seal ring comprises two sealings 11, contact site 12, between described two sealings 11, be " V ", described contact site 12 all is connected with two sealings 11, described inner seal ring 1 cross section is " Y " type, in the cavity that upper and lower shell 3,4 forms, be full of combustion gas, when the combustion gas wish is revealed from upper and lower shell 3,4 surface of contact, the combustion gas meeting forms an acting force to two sealings 11 of inner seal ring 1, make two sealing 11 distortion play self-styled effect, stop gas leakage, sealing effectiveness is more superior.
Angle between described two sealings 11 is 120 degree.
By adopting technique scheme, by the angle between two sealings 11, be 120 degree, can improve the sealing effectiveness of inner seal ring 1.
Described inside and outside O-ring seal 1,2 is made for elastomeric material.
Described external seal 2 is " U " type.
By adopting technique scheme, exterior seal ring 2 is arranged and is " U " type, simple in structure, easy for installation, gas meter, flow meter is formed to secondary seal.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model also not only is confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not break away under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
