Description
Technical field
The utility model relates to seal ring technical field, particularly relates to a kind ofly to diffuse seal ring for gas pipe line.
Background technique
Diffusion valve seal ring is mainly used in gas pipe line sealing.Usual silicone rubber seal ring bears pressure and is less than 3 barometric pressure, and working life is short, and General Life only has 1-2 month, there is needs often replacing, renewal cost is high, trouble, safety coefficient are not high enough, easily goes out dangerous shortcoming.
Model utility content
The purpose of this utility model is for the problems referred to above deficiency, provides a kind of and diffuses seal ring for gas pipe line, has that structure is simple, cost is low, increase the service life, load performance is better, add flexible advantage.
In order to achieve the above object, the utility model is by the following technical solutions:
A kind ofly diffuse seal ring for gas pipe line, it is provided with ringwise sealed body, rounded annular flange, stiffening rib, described annular flange is located at described sealed body one side, described sealed body endoporus and described annular flange endoporus etc. are large, described annular flange external diameter is greater than described sealed body external diameter, the outside that described sealed body and described annular flange are fitted is step-like, described sealed body and described annular flange are formed in one, described sealed body coordinates with described annular flange and forms skeleton, described sealed body inside is coated with ringwise stiffening rib.
Described stiffening rib is by the stiffening rib made in banded iron net.
Described stiffening rib is the stiffening rib be made up of polytetrafluoroethylmaterial material.
The utility model adopts said structure, has that structure is simple, cost is low, increase the service life, load performance is better, add flexible advantage.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model ctting agency schematic diagram.
Below by way of the drawings and specific embodiments, the utility model is further described.
Embodiment
As depicted in figs. 1 and 2, the utility model is a kind of diffuses seal ring for gas pipe line, it is provided with ringwise sealed body, rounded annular flange 1, stiffening rib 5, described annular flange 1 is located at described sealed body one side, described sealed body endoporus and described annular flange 1 endoporus etc. are large, described annular flange 1 external diameter is greater than described sealed body external diameter, the outside that described sealed body and described annular flange are fitted is step-like, described sealed body and described annular flange 1 are formed in one, described sealed body coordinates with described annular flange 1 and forms skeleton, described sealed body inside is coated with ringwise stiffening rib 5.
Described stiffening rib 5 is by the stiffening rib made in banded iron net.
Described stiffening rib 5 is the stiffening rib be made up of polytetrafluoroethylmaterial material.
Further, the cross-section area of described stiffening rib 5 is than cross-section area 70% also little of described sealed body.
Further, described stiffening rib 5 can be cone shape annular.
Further, described sealed body is followed successively by conus portion 3 and cylindrical part 2 from top to bottom, and described conus portion 3 outer side wall is the conical camber that one end is amplified gradually toward annular flange 2 direction.
Further, the height of described conus portion 3 is higher than the height of described cylindrical part 2.
The utility model adopts said structure, has that structure is simple, cost is low, increase the service life, load performance is better, add flexible advantage.
More than illustrate and unrestricted the technical solution of the utility model, every technology not departing from the utility model spirit, all belongs in right of the present utility model.
