Abstract
The utility model relates to a rubber sealing ring, and a protruding platform is positioned on the outside flank of the sealing ring basal body. Two wave crests are arranged on the sealing face, and a dip angle Alpha is arranged between the edges of the wave crests. The sealing ring basal body is provided with a metal ring inside. The utility model has the advantages of that: the sealing ring is not easy to distort and fall down in the transportation journey or the movement process of starting and shutting with more reliable sealing function, and the utility model is applicable for the use in high temperature.
Description
Affiliated technical field
The utility model relates to a kind of seal ring, especially a kind of rubber seal that is applied to glasses valve.
Background technique
The present glasses valve that uses of metallurgy industry blast furnace system, its seal ring is general to adopt flat O shape circle, though sealing effect is pretty good, in transit or in the valve opening and closing movement process, seal ring easily comes off in the groove of flashboard.
Summary of the invention
In order to overcome the existing caducous deficiency of glasses valve seal ring, the utility model provides a kind of rubber seal of difficult drop-off.
The technological scheme that its technical problem that solves the utility model adopts is, a kind of rubber seal, and there is a boss in the outside of seal ring matrix, and there is the twice crest at the sealing surface place, forms an inclination alpha between the limit of crest, also has an eyelet in the seal ring matrix.
The beneficial effects of the utility model be valve in transit or to open and close in the movement process seal ring yielding and come off, and sealability is more reliable, suitablely at high temperature uses.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is embodiment's a tectonic maps.
Among the figure: 1. boss; 2. crest; 3. eyelet; 4. seal ring matrix.
Embodiment
As shown in Figure 1, a kind of rubber seal, there is a boss 1 in the outside of seal ring matrix 4, and there is twice crest 2 at the sealing surface place, forms an inclination alpha between the limit of crest 2, and the existence of twice crest 2 makes sealing effect better, also has an eyelet 3 in seal ring matrix 4.Owing to there is boss 1, make the rubber seal difficult drop-off, because the existence of eyelet 3 makes rubber seal not yielding, suit under the condition of high temperature, to use.
Claims (1)
1, a kind of rubber seal, there is a boss in the outside of seal ring matrix, and there is the twice crest at the sealing surface place, forms an inclination alpha between the limit of crest, it is characterized in that: also have an eyelet in the seal ring matrix.
