Abstract
A kind of soft seal device with outer hard position limit cycle, relate to a kind of soft seal device, outer edge surface (6) middle part in rubber ring (5) is provided with circular trough (10), being embedded in the circular trough (10) that circular ring (2) embeds described rubber ring (5) of hard position limit cycle inner side, be provided with outer ring plate (1) in hard position limit cycle outside, described outer ring plate (1) and be embedded in and be provided with connecting ring (3) between circular ring (2); The utility model is embedded in circular ring by the circular trough at rubber ring, in use, prevents the aging displacement of rubber ring by being embedded in when circular ring, outer ring plate make rubber ring realize sealing, and the utility model can guarantee that obturation effect meets the requirements.
Description
[technical field]
The utility model relates to a kind of soft seal device, is specifically related to a kind of soft seal device with outer hard position limit cycle.
[background technique]
Known, what in conventional fluid pipeline interface, use is that annular seal ring " is also O shape circle ", this airtight requirement that can meet water or other liquid medium, but higher for the requirement of pipe joint " adpting flange place " in chemical industry, especially for explosive gasoline or other oil product, not only also very high for weatherability requirement, and need seal ring to there is strictly airtight requirement; Existing O shape rubber ring in use, is subject to the smooth situation impact of workmanship, rigidity of flange and the flange interface of bolts and nuts, loses due obturation effect after stressed elongation.
[summary of the invention]
In order to overcome deficiency of the prior art, the utility model discloses a kind of soft seal device with outer hard position limit cycle, be embedded in circular ring by the circular trough at rubber ring, in use, prevent the aging displacement of rubber ring by being embedded in when circular ring, outer ring plate make rubber ring realize sealing, the utility model can guarantee that obturation effect meets the requirements.
In order to realize described goal of the invention, the utility model adopts following technology:
A kind of soft seal device with outer hard position limit cycle, comprise rubber ring, hard position limit cycle, outer edge surface middle part at rubber ring is provided with circular trough, being embedded in the circular trough that circular ring embeds described rubber ring of hard position limit cycle inner side, be provided with outer ring plate in hard position limit cycle outside, described outer ring plate and be embedded in and be provided with connecting ring between circular ring.
The described soft seal device with outer hard position limit cycle, between the outer edge surface of described rubber ring and circular trough, be provided with notch, described notch is "=" shape structure, outer edge surface in "=" shape structure notch outside is respectively equipped with step up and down, in the notch of connecting ring in described "=" shape structure, the described up/down steps in corresponding notch outside, the two ends up and down of described outer ring plate.
The described soft seal device with outer hard position limit cycle, the inner face of described rubber ring is the planar annular of erectting.
The described soft seal device with outer hard position limit cycle is provided with at least two projection bars in the upper side of rubber ring.
The described soft seal device with outer hard position limit cycle is provided with at least two lower convexity bars in the bottom surfaces of rubber ring.
Owing to having adopted technique scheme, the utlity model has following beneficial effect:
The soft seal device with outer hard position limit cycle described in the utility model, by the arranged outside circular trough at rubber ring, to be embedded in circular ring embeds in circular trough, in use, when making rubber ring realize sealing, prevent the aging displacement of rubber ring by being embedded in circular ring, outer ring plate, outer ring plate, be embedded in circular ring and play the double effects to rubber ring sizing and reinforcement, can guarantee that rubber ring using process can lengthening deformation, the projection bar, the lower convexity bar that on the top and bottom of described rubber ring, arrange, can guarantee that obturation effect meets the requirements; The utility model is simple in structure, and obturation effect is better than prior art.
[brief description of the drawings]
Fig. 1 is perspective view of the present utility model;
Fig. 2 is rubber ring structural representation of the present utility model;
Fig. 3 is the assembly structure schematic diagram of rubber ring of the present utility model and hard position limit cycle;
In figure: 1, outer ring plate; 2, be embedded in circular ring; 3, connecting ring; 4, inner face; 5, rubber ring; 6, outer edge surface; 7, upper side; 8, projection bar; 9, lower convexity bar; 10, circular trough; 11, step; 12, notch.
[embodiment]
With reference to the following examples, can explain in more detail the utility model; But it should be noted that the utility model is not limited to following embodiment; Open the purpose of this utility model is intended to protect all changes and improvements within the scope of the utility model.
By reference to the accompanying drawings 1, the soft seal device with outer hard position limit cycle described in 2 or 3, comprise rubber ring 5, hard position limit cycle, the planar annular of the inner face 4 of rubber ring 5 for erectting, outer edge surface 6 middle parts at described rubber ring 5 are provided with circular trough 10, between the outer edge surface 6 of described rubber ring 5 and circular trough 10, be provided with notch 12, described notch 12 is "=" shape structure, outer edge surface 6 in "=" shape structure notch 12 outsides is respectively equipped with step 11 up and down, being embedded in the circular trough 10 that circular ring 2 embeds described rubber ring 5 of hard position limit cycle inner side, be provided with outer ring plate 1 in hard position limit cycle outside, described outer ring plate 1 and be embedded in and be provided with connecting ring 3 between circular ring 2, in the notch 12 of connecting ring 3 in described "=" shape structure, the described up/down steps 11 in corresponding notch 12 outsides, two ends up and down of described outer ring plate 1, in the upper side 7 of rubber ring 5, be provided with at least two projection bars 8, in the bottom surfaces of rubber ring 5, be provided with at least two lower convexity bars 9.
Implement the soft seal device with outer hard position limit cycle described in the utility model, when design, by the arranged outside notch 12 at rubber ring 5, circular trough 10, wherein notch 12 is highly slightly less than the inner cavity height of circular trough 10, the described circular ring 2 that is embedded in embeds in circular trough 10, and connecting ring 3 is maked somebody a mere figurehead at described notch 12; The utility model is placed between the adpting flange of two docking pipelines, by bolt, two adpting flanges are compressed the utility model, at this moment be embedded in circular ring 2, outer ring plate 1 and when making rubber ring 5 realize sealing two adpting flange interface, prevent the aging displacement of rubber ring 5, outer ring plate 1, be embedded in circular ring 2 and play rubber ring 5 is shaped and the double effects of reinforcement, can guarantee that rubber ring using process can lengthening deformation, position of the present utility model, shape are kept for a long time, also can not there is displacement in rubber ring, guaranteed the leak tightness between two adpting flanges.
The utility model does not describe part in detail for prior art.
