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.
