Abstract
The utility model is related to sealing valve field, more particularly to a kind of seal assembly.Low pressure seal valve macromolecule strengthens seal assembly, including a sealing ring, and sealing ring is that a turn is embedded with a rubber seal, rubber seal；Rubber seal is coated with one layer of carbon fiber tape；Carbon fiber tape is wound in outside rubber seal in the shape of a spiral, and the area coverage of carbon fiber tape is the 50%~60% of rubber seal surface area.Compared to the seal assembly being only made with tradition of elastomeric material, this patent is inside and outside while strengthening the intensity of rubber seal.Being embedded in the turn inside rubber seal can prevent rubber seal to be broken, and being coated on the carbon fiber tape outside rubber seal is not easily broken rubber seal.Moreover, when rubber seal is being stretched or is being squeezed, the carbon fiber tape being wound in the shape of a spiral outside rubber seal can allow rubber seal to have enough expansion or shrink space.
Description
Technical field
The utility model is related to sealing valve field, more particularly to a kind of seal assembly.
Background technology
Low pressure seal valve is generally required for ensureing the sealing of itself with some seal assemblies, is generally used for making sealing
Preferably, but without relatively good intensity, rupture or disconnected easily occurs for the main material or rubber of component, the sealing of rubber
The phenomenon opened, it is often necessary to changed, service life is very short, so as to influence the sealing of low pressure seal valve.
Utility model content
The purpose of this utility model is that providing a kind of low pressure seal valve macromolecule strengthens seal assembly, and solution is above-mentioned at least
One technical problem.
The technical problem that the utility model is solved can be realized using following technical scheme：
Low pressure seal valve macromolecule strengthens seal assembly, including one is used for the sealing ring of sealing low pressure sealing valve, described close
Seal is a rubber seal, it is characterised in that a turn is embedded with the rubber seal, the turn is with described
Centered on the center of rubber seal, after annularly surrounding, join end to end and form；
The turn is formed by steel wire spiral coiling；
The rubber seal outsourcing is wound with one layer of carbon fiber tape；The carbon fiber tape is wound in the rubber in the shape of a spiral
Outside sealing ring, and the area coverage of the carbon fiber tape is the 50%~60% of the rubber seal surface area.
Compared to the seal assembly being only made with tradition of elastomeric material, this patent is inside and outside while strengthening rubber seal
Intensity.Being embedded in the turn inside rubber seal can prevent sealing ring to be broken, and be coated on outside rubber seal
Carbon fiber tape it is soft, but intensity but be more than steel, be not easily broken rubber seal.Moreover, working as rubber seal
When stretching or being squeezed, the carbon fiber tape being wound in the shape of a spiral outside rubber seal is not completely enclosed, Neng Gourang
Rubber seal has enough expansion or shrink space.
In addition, when rubber coil is being stretched or is being squeezed, the turn being embedded in rubber seal is also same
When the effect with stretching, the elasticity of rubber seal in itself is not influenceed at all.
The external diameter of the steel wire is 0.5mm~1mm.Ensure its intensity and ductility.The external diameter of the steel wire is preferably
0.8mm。
The width of the carbon fiber tape is 0.2cm~0.5cm.It is convenient to be wrapped in outside rubber seal.The carbon fiber
The width of band is preferably 0.3cm.
The thickness of the carbon fiber tape is 0.5mm~1mm.Ensure the intensity and corrosion resistance of rubber seal.The carbon
The thickness of fiber band is preferably 0.8mm.
The turn surface scribbles one layer of antirust coat.Prevent getting rusty for turn from causing to become fragile, be broken.
The upper surface of the rubber seal is a plane with lower surface, and the section of the rubber seal is by lower edges
In the middle part of to section, area is gradually reduced.The desired sealed part so that rubber seal is more fitted, so as to reach better seal
Property.
Brief description of the drawings
Fig. 1 is a kind of part-structure schematic diagram of structure of the utility model；
Fig. 2 is the sectional view of another structure of the utility model.
Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face, which combines to be specifically illustrating, is expanded on further the utility model.
Reference picture 1, Fig. 2, low pressure seal valve macromolecule strengthen seal assembly, including one is used for the close of sealing low pressure sealing valve
Seal, sealing ring is that a turn 1 is embedded with a rubber seal 2, rubber seal 2, and turn 1 is with rubber seal 2
Center centered on, after annularly surrounding, join end to end and form；Turn 1 is formed by steel wire spiral coiling；Rubber seal 2
Outsourcing is wound with one layer of carbon fiber tape；Carbon fiber tape is wound in outside rubber seal 2 in the shape of a spiral, and the coverage rate of carbon fiber tape
Product is the 50%~60% of the surface area of rubber seal 2.Compared to the seal assembly being only made with tradition of elastomeric material, this patent
Inside and outside while strengthening the intensity of rubber seal 2.Sealing ring can be prevented by being embedded in the turn 1 inside rubber seal 2
It is broken, the carbon fiber tape 3 being coated on outside rubber seal 2 is soft, but intensity is but more than steel, makes rubber close
Seal 2 is not easily broken.Moreover, when rubber seal 2 is being stretched or is being squeezed, rubber seal is wound in the shape of a spiral
Outer carbon fiber tape 3 can allow rubber seal to have enough expansion or shrink space.In addition, being embedded in rubber seal
Turn 1 also there is the effect of stretching simultaneously, the elasticity of rubber seal in itself is not influenceed at all.The external diameter of steel wire is
0.5mm~1mm.Ensure its intensity and ductility.The external diameter of steel wire is preferably 0.8mm.
The width of carbon fiber tape 3 is 0.2cm~0.5cm.Preferably 0.3cm.It is convenient to be wrapped in outside rubber seal.Carbon
The thickness of fiber band is 0.5mm~1mm.Preferably 0.8mm.Ensure the intensity and corrosion resistance of rubber seal.
The surface of turn 1 scribbles one layer of antirust coat.Prevent getting rusty for turn 1 from causing to become fragile, be broken.
The upper surface of rubber seal and lower surface are a plane, and the section of rubber seal is by lower edges into section
Portion, area is gradually reduced.The desired sealed part so that rubber seal is more fitted, so as to reach better seal.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
