Abstract
The utility model is related to valve field, more particularly to a kind of seal assembly.High pressure sealing valve macromolecule strengthens seal assembly, including a sealing ring, and sealing ring is that a turn is embedded with a rubber seal, rubber seal, and turn is centered on the center of rubber seal, after annularly surrounding, and joins end to end and forms；Turn is formed by steel wire spiral coiling；Rubber seal outsourcing is wound with one layer of basalt fibre band, and basalt fibre band is wound in outside rubber seal in the shape of a spiral, and the area coverage of basalt fibre band is the 70%~80% of rubber seal surface area.This patent is inside and outside while strengthening the intensity of rubber seal.Being embedded in the turn inside rubber seal can prevent sealing ring to be broken, and when rubber coil is being stretched or is being squeezed, the turn being embedded in rubber seal does not influence the elasticity of rubber seal in itself at all while have the effect of stretching yet.
Description
Technical field
The utility model is related to valve field, more particularly to a kind of seal assembly.
Background technology
High pressure sealing 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.
Especially used in the hyperbaric environment of high pressure sealing valve, seal assembly is more prone to be damaged, service life is very
It is short, so as to influence the sealing of high pressure sealing valve.
Utility model content
The purpose of this utility model is that providing a kind of high pressure sealing 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：
High pressure sealing valve macromolecule strengthens seal assembly, including one is used to seal the sealing ring of high 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 basalt fibre band；The basalt fibre band is wound in the shape of a spiral
Outside the rubber seal, and the basalt fibre band area coverage be the rubber seal surface area 70%~
80%.
The seal assembly being only made compared to 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 when rubber coil is being drawn
When stretching or being squeezed, the turn being embedded in rubber seal does not influence rubber at all also while have the effect of stretching
The elasticity of glue sealing ring in itself.
The ring structure of this patent substantially increases the intensity of sealing ring while its sealing is not influenceed, so that
Sealing ring is had bigger intensity, improve the service life of sealing ring.
Be coated on the basalt fibre band outside rubber seal there is high intensity, it is corrosion-resistant the features such as, make rubber seal
Circle is not easily broken.And helical form, the basalt fibre band do not closed make rubber seal when stretching and being squeezed, and have foot
Enough expansions or shrink space.
The external diameter of the steel wire is less than 0.5mm.It can be embedded in rubber seal, and with certain intensity.
The external diameter of the rubber seal is 1mm~2mm.Keep there can be certain intensity in the case of sealing.
The thickness of the rubber seal is preferably 1.5mm.
The thickness of the basalt fibre band is 0.5mm~1mm.Preferably 0.8mm.Ensure rubber seal intensity and
Corrosion resistance.
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 perspective view of 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, high pressure sealing valve macromolecule enhancing seal assembly, including one be used to seal the sealing of high pressure sealing valve
Circle, 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
Centered on center, after annularly surrounding, join end to end and form；Turn 1 is formed by steel wire spiral coiling；Outside rubber seal 2
It is surrounded with one layer of basalt fibre band；Basalt fibre band is wound in outside rubber seal 2 in the shape of a spiral, and basalt fibre
The area coverage of band is the 70%~80% of the surface area of rubber seal 2.The sealing being only made compared to tradition of elastomeric material
Component, this patent is inside and outside while strengthening the intensity of rubber seal 2.The turn 1 being embedded in inside rubber seal 2 can
Prevent sealing ring to be broken, and when rubber coil 1 is being stretched or is being squeezed, be embedded in rubber seal 2
Turn 1 also there is the effect of stretching simultaneously, the elasticity of of rubber seal 2 itself is not influenceed at all.
Be coated on the basalt fibre band outside rubber seal 2 there is high intensity, it is corrosion-resistant the features such as, make rubber seal
Circle is not easily broken.And helical form, the basalt fibre band do not closed make rubber seal when stretching and being squeezed, and have foot
Enough expansions or shrink space.The ring structure of this patent substantially increases sealing while its sealing is not influenceed
The intensity of circle, so that sealing ring has bigger intensity, improves the service life of sealing ring.
The external diameter of steel wire is less than 0.5mm.It can be embedded in rubber seal, and with certain intensity.
The external diameter of rubber seal is 1mm~2mm.Keep there can be certain intensity in the case of sealing.Rubber
The thickness of sealing ring is preferably 1.5mm.
The thickness of basalt fibre band is 0.5mm~1mm.Preferably 0.8mm.Ensure the intensity and corrosion resistant of rubber seal
Corrosion.
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
