Abstract
The utility model relates to a connecting and sealing device, which comprises a sealing ring (2), a connecting part (1) and a metal pipe (4), wherein a plurality of radial convex areas are arranged on the internal circle surface and the external circle surface of the sealing ring (2), the internal circle surface of the sealing ring (2) is closely matched with the metal pipe (4), and the external circle surface of the sealing ring (2) is closely matched with the connecting part (1). The sealing performance of the connecting and sealing device is good, and the cost is low.
Description
Technical field
The utility model relates to a kind of connection seal arrangement that is used on the motor car engine conduit pipeline.
Background technique
At present, being used for of prior art connects seal arrangement on the motor car engine conduit pipeline, form by seal ring, metal tube, link, during use fixedly connected the connection bump place of metal tube with link in the first connection bump place that is enclosed within seal ring on the metal tube and slides to metal tube with seal ring again.But, because the existing seal connection that is used on the motor car engine conduit pipeline uses common seal ring, be that its sealing surface is level and smooth face, in use, because the machining accuracy problem is difficult to guarantee that seal ring inner headed face, periphery contact fully with metal pipe-wall, link wall, thereby cause its sealing effect relatively poor, if improve the precision of seal ring, then need higher processing cost again.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of good sealing effect and cost low connection seal arrangement.
The technological scheme that provides of the present utility model is, a kind of connection seal arrangement with following structure is provided, it comprises seal ring, link and metal tube, the inner headed face of described seal ring, periphery are provided with a plurality of radial protrusions, the inner headed face of described seal ring and described metal tube drive fit, the periphery of described seal ring and described link drive fit.
After adopting above structure, the utility model compared with prior art has following advantage:
What the utility model connected the seal arrangement use is that inside and outside disc is provided with a plurality of radial protrusions, under the effect of metal tube and link, bulging deformation can guarantee that seal ring inner headed face, periphery contact fully with metal pipe-wall, link wall, and sealing effect is better.
As improvement, a stiffening ring has been installed in the seal ring of the present utility model, but the pressure of effective support metal tube and link has increased the intensity of seal ring, thereby play sealing, strengthen to connect effect.
Description of drawings
Fig. 1 is that the utility model connects the seal arrangement cross-sectional view.
Fig. 2 is that the utility model connects the seal arrangement erection drawing.
Shown in the figure 1, link, 2, seal ring, 3, stiffening ring, 4, metal tube.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the utility model connects seal arrangement, comprise seal ring 2, link 1, stiffening ring 3 and metal tube 4, the inner headed face of seal ring 2, periphery are provided with a plurality of radial protrusions, the internal diameter of seal ring 2 is slightly less than the external diameter of metal tube 4, the external diameter of seal ring 2 is slightly larger than the internal diameter of link 1, the inner headed face of seal ring 2 and metal tube 4 drive fits, its periphery and link 1 drive fit.Described seal ring 2 is generally the profile of tooth seal ring.
Claims (2)
1, a kind of connection seal arrangement, comprise seal ring (2), link (1) and metal tube (4), it is characterized in that: inner headed face, the periphery of described seal ring (2) are provided with a plurality of radial protrusions, the inner headed face of described seal ring (2) and described metal tube (4) drive fit, the periphery of described seal ring (2) and described link (1) drive fit.
2, connection seal arrangement according to claim 1, it is characterized in that: described seal ring (2) is for flexible, also be provided with the stiffening ring (3) of rigidity in it, described stiffening ring (3) is embedded in the described seal ring (2) and by described seal ring (2) and coats.
