Abstract

The utility model provides a double-side positioning sealing ring, which comprises a cylinder wall and a coaxial inner hole which are integrally formed by injecting, wherein the cylinder wall comprises a sealing portion and a connecting portion, a sealing surface of the sealing portion is an arc surface, and plummer blocks are coaxially arranged on the circumference surface of the inner hole. The double-side positioning sealing ring has the beneficial effects that the arc surface is used to seal, is easy to generate elastic deformation, has better sealing performance, can effectively compensate the deformation when being affected by various external factors for long time, and prolongs service life of a sealing ring. The two coaxial plummer blocks are arranged on the inner circumference surface, can accurately position axial positions in two directions when assembling, and can conveniently position sealing parts which are coaxially arranged in the sealing ring. A lip portion is arranged in the sealing portion, and prevents external dust from entering the sealing parts, and a metal elastic part is arranged in the lip portion, and utilizes elastic force of the metal elastic part to supply sealing pressure, thereby guaranteeing the sealing pressure not to be affected by work environment, abrasion of the sealing ring and material aging, and broadening applicable environment.

Description

Dual contact seal ring
Technical field
The utility model relates to rubber seal products field, more specifically to a kind of dual contact seal ring.
Background technique
Seal ring is mainly used in preventing from the dielectric leakages such as grease, profit from preventing that extraneous medium from entering in seal arrangement in seal arrangement simultaneously, is requisite accessory in various water-tight equipments, valve, pipeline.Existing seal ring is the simple circle loop configuration of different size, in use, be subject to for a long time the various factors such as temperature, pressure, burn into wearing and tearing, easily deform, cause sealing effect variation, even leak, especially in the high seal arrangement of some required precisions, easily cause greater loss, and change seal ring complicated operation, labor intensive material resources, increases cost.
At present, various mechanical seal mostly adopts the mode of traditional rubber seal, and the sealing means of this seal ring is face sealing.In use, seal ring easily occur to reverse under external force and causes local leakage, or fatigue aging occurs loses sealing effect, thereby causes the seal failure of whole seal ring.Therefore, existing seal ring is short working life, and sealing effect is general, the in the situation that of local leakage, can not compensate by self-sealing, can only be useful in sealing occasion generally.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of dual contact seal ring is provided.
The purpose of this utility model is achieved by following technical proposals.
A dual contact seal ring, comprises the barrel of integrated injection molding and coaxial endoporus, and described barrel consists of sealed department and joint, and the sealing surface of described sealed department is set to cambered surface, and described endoporus circumferential surface is coaxially arranged with the pillow block for locating.
The radian of described cambered surface is 120 °-180 °.
It is one-body molded and for dustproof lip portion that described sealed department inner side is provided with.
Described lip portion inner side be provided with described lip portion inside the metallic elastic part that adapts of shape.
The U-shaped spring sheet that described metallic elastic part is several adjacent arrangements.
Described sealed department height and described joint aspect ratio are 1:1-2.
Described pillow block width and described sealed department aspect ratio are 1:1-2.
The beneficial effects of the utility model are:
1, the utility model cambered surface is for sealing, and the convenient location of installing, is easy to assembling, for sealing, more easily there is elastic strain in cambered surface, there is better sealability, and can effectively compensate distortion when standing multiple extraneous factor for a long time and affect, extend the working life of seal ring;
2, on the utility model inner peripheral surface, be shaped with two coaxial pillow blocks, two-wayly during assembling all can locate exactly axial position, be convenient to location and be coaxially arranged on the Sealing in seal ring;
3, the utility model is provided with lip portion in sealed department inner side, and lip portion can be used for preventing that outside dust from entering in Sealing, and the sealing effect of enhanced leaktightness part, extends its working life;
4, the utility model is provided with metallic elastic part in lip portion inner side, utilized the elastic force of metallic elastic part that sealing load is provided, guaranteed that its sealing load is not subject to the wearing and tearing of working environment and seal ring and the aging impact of material, thereby widened suitable environment.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model.
In figure: 1, barrel, 2, endoporus, 3, pillow block, 4, sealed department, 5, joint, 6, lip portion.
Embodiment
Below by specific embodiment, the technical solution of the utility model is further described.
A kind of dual contact seal ring, comprise the barrel 1 of integrated injection molding and coaxial endoporus 2, barrel 1 consists of sealed department 4 and joint 5, and the sealing surface of sealed department 4 is set to cambered surface, the radian of cambered surface is 120 °-180 °, and endoporus 2 circumferential surfacies are coaxially arranged with pillow block 3.
The present embodiment cambered surface is for sealing, and the convenient location of installing, is easy to assembling, for sealing, more easily there is elastic strain in cambered surface, there is better sealability, and can effectively compensate distortion when standing multiple extraneous factor for a long time and affect, extend the working life of seal ring; On inner peripheral surface, be shaped with two coaxial pillow blocks, two-wayly during assembling all can locate exactly axial position, be convenient to location and be coaxially arranged on the Sealing in seal ring.
Sealed department 4 inner sides are provided with integrated lip portion 6.
The present embodiment is provided with lip portion in sealed department inner side, and lip portion can be used for preventing that outside dust from entering in Sealing, and the sealing effect of enhanced leaktightness part, extends its working life.
Lip portion 6 inner sides are provided with the metallic elastic part (not shown) adapting with lip portion 6 inner side shapes.
The U-shaped spring sheet that metallic elastic part (not shown) is several adjacent arrangements.
The present embodiment is provided with metallic elastic part in lip portion inner side, has utilized the elastic force of metallic elastic part that sealing load is provided, and has guaranteed that its sealing load is not subject to the wearing and tearing of working environment and seal ring and the aging impact of material, thereby has widened suitable environment.
In the present embodiment, sealed department 4 is highly 7.1mm, and joint 5 is highly 6mm, and pillow block 3 width are 4.1mm.
