Abstract
Disclosed is an energy-saving sealing ring. The problems that the existing sealing ring is short in service life, after the elasticity of the existing sealing ring is reduced, media easily leak, and the sealing performance is greatly reduced are solved. The energy-saving sealing ring is characterized in that a first clamp ring (11) extends from the inner side of a ring body (1); a second clamp ring (12) extends from the outer side of the ring body (1); and a compensation spring (2) is arranged between the first clamp ring (11) and the second clamp ring (12). Because the spring with a sealing compensation function is placed in the energy-saving sealing ring, the sealing performance of the energy-saving sealing ring is excellent, and the running stability of a sealing part can be guaranteed for a long time.
Description
Technical field
The utility model relates to a kind of seal ring, is specifically related to a kind of accumulation of energy seal ring.
Background technique
O type rubber ring, owing to being subject to the performance impact of material, is subject to certain restriction at aspects such as bearing pressures, and in particular for the rubber ring of sealing, the extruding of main outer power makes its distortion realize sealing.Under the impact of long term exterior extruding, temperature variation, self elastic force declines, and sealing cannot compensate, and causes sealability to decline to a great extent, and easily occurring the phenomenon of leaking affects mechanism's sealability.
Model utility content
In order to overcome the deficiency of background technique, the utility model provides a kind of accumulation of energy seal ring, has mainly solved existing seal ring short working life, and self elastic force easily occurs dielectric leakage, the problem that sealability declines to a great extent after declining.
The technological scheme that the utility model adopts is: a kind of accumulation of energy seal ring, comprise ring body, and described ring body inner side is extended with the first clamp ring, and described ring body outside is extended with the second clamp ring, between the first described clamp ring and the second clamp ring, is provided with counterbalance spring.
Between described ring body and the first clamp ring, the second clamp ring, form resettlement groove.
Described the first clamp ring, the second clamp ring are circular arc type, and the first described clamp ring, the second clamp ring are to resettlement groove internal bend.The first described clamp ring, the second clamp ring and counterbalance spring interference fit.
Described ring body, the first clamp ring, the second clamp ring consist of teflon.
The beneficial effects of the utility model are: due to the built-in spring that has compensation sealing function, sealability is more outstanding, can guarantee the long time stability of sealing part works.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional view of the present utility model.
1-ring body in figure, 11-the first clamp ring, 12-the second clamp ring, 2-counterbalance spring, 3-resettlement groove.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1 with Figure 2, a kind of accumulation of energy seal ring, comprises ring body 1, and described ring body 1 inner side is extended with the first clamp ring 11, and described ring body 1 outside is extended with the second clamp ring 12, between the first described clamp ring 11 and the second clamp ring 12, is provided with counterbalance spring 2.
Between described ring body 1 and the first clamp ring 11, the second clamp ring 12, form resettlement groove 3.Be used for placing counterbalance spring 2.
Described the first clamp ring 11, the second clamp ring 12 are circular arc type, and the first described clamp ring 11, the second clamp ring 12 are to resettlement groove 3 internal bend.Clamping counterbalance spring 2, does not come off it.Described the first clamp ring 11, the second clamp ring 12 and counterbalance spring 2 interference fit., there is less amount of deformation in clamping counterbalance spring 2.
Described ring body 1, the first clamp ring 11, the second clamp ring 12 consist of teflon.Meet rugged environment high pressure resistant, high temperature resistant, low temperature resistant, acid-alkali-corrosive-resisting.
The concrete use of the utility model is as follows: the coated counterbalance spring 2 of ring body 1, relies on the first clamp ring 11, the second clamp ring 12 to realize crush seal.Counterbalance spring 2 is interference fit with the side of resettlement groove 3.After seal ring work a period of time, due to reasons such as wearing and tearing, extruding, distortion, size can change to some extent, and now the counterbalance spring 2 in resettlement groove 3 starts to support to come and realizes sealing compensation, the sealing of compensation can guarantee that Sealing works on, and realizes the function of permanent stabilized seal.
The beneficial effect of model utility is: due to the built-in spring that has compensation sealing function, sealability is more outstanding, can guarantee the long time stability of sealing part works.
