Abstract
The utility model discloses a rubber sealing ring which comprises a rubber body (1). An inner surface layer (11) and/or an outer surface layer (12) of the rubber body (1) are/is pressed to form a texture structure layer. The texture structure layer is a ripple structure layer. In the rubber sealing ring provided by the utility model, the inner surface layer and/or the outer surface layer of the rubber body are/is subjected to pressing processing to form the texture structure, so that micropores or micro gaps in the inner surface layer and/or the outer surface layer of the rubber body are deformed or compounded to disappear, a medium is avoided permeating through the micropores or the micro gaps in the application process, the sealing performance of the rubber sealing ring is improved and the service life of the rubber sealing ring is prolonged.
Description
Technical field
The utility model relates to Sealing, relates in particular to a kind of rubber seal.
Background technique
Rubber seal is most widely used Sealing, is applied in the product to play the sealed against leakage function.Rubber seal is to be carrier with rubber.In the forming process of rubber seal, possibly generate a large amount of micropores or micro chink in the rubber structure, especially micropore in the inner surface layer of rubber seal and the external layer rubber structure or micro chink will reduce the sealability of rubber seal significantly.For example; In the rubber seal sulfidization molding process, in rubber structure, produce a large amount of micropores, if above-mentioned rubber seal is applied in the lubrication system of high pressure; Lubricant oil can permeate through micropore or micro chink and produce leakage, has reduced the sealability of seal ring; Perhaps above-mentioned rubber seal is applied in the pressurized container of highly corrosive, highly corrosive medium or gas can permeate the corrosion that causes rubber seal through micropore or micro chink, thereby have reduced the sealability and the working life of rubber seal.
The model utility content
To above defective, the utility model provides a kind of rubber seal, improve the sealability of rubber seal, improve the working life of rubber seal.
For realizing above-mentioned purpose, the utility model is realized through following technological scheme:
A kind of rubber seal comprises rubber body, at the inner surface layer and/or the external layer compacting formation texture structure layer of rubber body.
Preferably, said texture structure layer is the ripple struction layer.
Compared with prior art, the utlity model has following beneficial effect:
In a kind of rubber seal that the utility model proposes; Inner surface layer and/or external layer in rubber body carry out compression process to form the texture structure layer; Thereby make inner surface layer and/or the micropore in the external layer of rubber body or micro chink be able to distortion or compound disappearance; Avoid permeating through micropore or micro chink, improved the sealability and the working life of rubber seal in the application process medium.
Description of drawings
According to embodiment and accompanying drawing the utility model is done further explain below.
Fig. 1 is the section plan of a kind of rubber seal of the utility model proposition.
Fig. 2 is the three-dimensional cutaway view of a kind of rubber seal of the utility model proposition.
Embodiment
In order to solve the technical problem that exists in the existing technology; The technical thought that the utility model proposes can be applicable in the rubber seal of different structure and shape; For example can be applicable in bone type and the no bone type rubber seal, can be applicable in the rubber seal of different shapes such as O RunddichtringO, y-type seal ring, V-shaped seal ring, square RunddichtringO.
Below, not having bone type rubber seal with the O type is example, a kind of rubber seal that the utility model is proposed is elaborated.
As shown in Figure 1, the section plan of a kind of rubber seal that the utility model proposes.As shown in Figure 2, the three-dimensional cutaway view of a kind of rubber seal that proposes for the utility model.
With reference to accompanying drawing; A kind of rubber seal that the utility model proposes; Comprise rubber body 1; Form the texture structure layer in 11 compactings of the inner surface layer of rubber body 1, perhaps external layer 12 compactings in rubber body 1 form the texture structure layer, perhaps all suppress forming the texture structure layer with external layer 12 in the inner surface layer 11 of rubber body 1.Said texture structure layer is preferably the ripple struction layer.
Inner surface layer 11 and/or external layer 12 through in rubber body 1 carry out compression process formation texture structure layer; Thereby make inner surface layer and/or the micropore in the external layer of rubber body or micro chink be able to distortion or compound disappearance; Avoid permeating through micropore or micro chink, improved the sealability and the working life of rubber seal in the application process medium.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the realization of the utility model does not receive the restriction of aforesaid way; As long as adopted method design of the utility model and the various improvement that technological scheme is carried out; Or the design of the utility model and technological scheme are directly applied to other occasion without improving, all in the protection domain of the utility model.
Claims (2)
1. a rubber seal comprises rubber body (1), it is characterized in that, inner surface layer (11) and/or external layer (12) compacting in rubber body (1) form the texture structure layer.
2. rubber seal as claimed in claim 1 is characterized in that, said texture structure layer is the ripple struction layer.
