Abstract
A kind of soft or hard composite seal device, relate to a kind of composite seal device, comprise rubber ring (5), interior steel ring (1) and outer rim (2), on the inner face of rubber ring (5) and outer edge surface, be respectively equipped with C shape groove (3), interior steel ring (1) and outer rim (2) embed respectively in the C shape groove (3) of rubber ring (5) inner face and outer edge surface; The dual reinforcement of steel ring and outer rim in the utility model utilizes, can guarantee that rubber ring using process can lengthening deformation, owing to being provided with respectively both sides concave face and raised item on the top and bottom of rubber ring, can guarantee that obturation effect meets the requirements.
Description
[technical field]
The utility model relates to a kind of composite seal device, is specifically related to a kind of soft or hard composite seal device.
[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 or hard composite seal device, the dual reinforcement of steel ring and outer rim in utilizing, can guarantee that rubber ring using process can lengthening deformation, owing to being provided with respectively both sides concave face and raised item on the top and bottom of rubber ring, can guarantee that obturation effect meets the requirements.
In order to realize described goal of the invention, the utility model adopts following technology:
A soft or hard composite seal device, comprises rubber ring, interior steel ring and outer rim, on the inner face of rubber ring and outer edge surface, is respectively equipped with C shape groove, and interior steel ring and outer rim embed respectively in the C shape groove of rubber ring inner face and outer edge surface.
Described soft or hard composite seal device, C shape groove notch place the be set to respectively=shape mouth on described rubber ring inner face and outer edge surface, namely the inner face of C shape groove and described rubber ring and outer edge surface are plane transition.
Described soft or hard composite seal device, is respectively equipped with both sides concave face in upper side, the bottom surfaces both sides of rubber ring, and wherein the upper side both sides of rubber ring are to lower recess, and the bottom surfaces both sides of described rubber ring are for upwards caving in.
Described soft or hard composite seal device is respectively equipped with at least one raised item on the concave face of the described both sides of described rubber ring upper side, bottom surfaces.
Owing to having adopted technique scheme, the utlity model has following beneficial effect:
Soft or hard composite seal device described in the utility model, by the inside and outside both sides at rubber ring, C shape groove is set respectively, interior steel ring and outer rim are embedded to C shape groove, in use, by rubber ring, realize sealing, interior steel ring and outer rim play the double effects of sizing and reinforcement, can guarantee that rubber ring using process can lengthening deformation, the both sides concave face and the raised item 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.

Fig. 2 is rubber ring cross section structure schematic diagram of the present utility model;
Fig. 3 is the assembly structure schematic diagram of rubber ring of the present utility model and interior steel ring, outer rim;
In figure: 1, interior steel ring; 2, outer rim; 3, C shape groove; 4, raised item; 5, rubber ring; 6, upper side; 7, both sides concave face; 8, bottom surfaces.
[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, soft or hard composite seal device described in 2 or 3, comprise rubber ring 5, interior steel ring 1 and outer rim 2, on the inner face of rubber ring 5 and outer edge surface, be respectively equipped with C shape groove 3, C shape groove 3 notch place be set to respectively=shape mouths on described rubber ring 5 inner faces and outer edge surface, namely C shape groove 3 is plane transition with inner face and the outer edge surface of described rubber ring 5, interior steel ring 1 and outer rim 2 embed respectively in the C shape groove 3 of rubber ring 5 inner faces and outer edge surface, upper side 6 at rubber ring 5, bottom surfaces 8 both sides are respectively equipped with both sides concave face 7, wherein upper side 6 both sides of rubber ring 5 are to lower recess, bottom surfaces 8 both sides of described rubber ring 5 are for upwards caving in, in described rubber ring 5 upper side 6, on the described both sides concave face 7 of bottom surfaces 8, be respectively equipped with at least one raised item 4.
Implement soft or hard composite seal device described in the utility model, by the inside and outside both sides at rubber ring 5, C shape groove 3 is set respectively, first at the interior injection viscose glue of C shape groove 3 during use, then interior steel ring 1 and outer rim 2 are embedded to C shape groove 3, by viscose glue, make interior steel ring 1 and outer rim 2 form one with the C shape groove 3 of rubber ring 5, by the rubber ring 5 after merging, interior steel ring 1 and outer rim 2 are placed between the adpting flange of two docking pipelines, by bolt, two adpting flanges are compressed the utility model, at this moment interior steel ring 1 and outer rim 2 and rubber ring 5 are had an effect simultaneously, rubber ring 5 positions of especially interior steel ring 1 and outer rim 2 restriction sizings, shape is kept for a long time, also can not there is displacement in rubber ring 5, guaranteed the leak tightness between two adpting flanges.
The utility model does not describe part in detail for prior art.
