Abstract
The invention discloses a kind of high-temperature flexible quartz fibre sealing ring, it is mainly used for the sealing between two abutments under high ambient conditions, it has, and there are one annular seal circle bodies in hollow structure, are characterized in that：The annular seal circle body is docked by the head and the tail both ends of the surface sealing of a quartz fibre casing, and the hollow cavity of the quartz fibre casing is filled with quartzy cotton material.Scheme as priority, the head and the tail both ends of the surface of the quartz fibre casing are sealed by high temperature adhesive docks.Further, the inclined sealing docking structure of the head and the tail both ends of the surface of the quartz fibre casing.The high-temperature flexible quartz fibre ring structure is simple, easy to use, of low cost, may replace traditional metal o-ring, and changing frequent occasion in closure size gives full play to its advantage.
Description
Technical field
The present invention relates to the fast sealing mounting technologies between hot environment lower component and component, in particular to a kind of resistance to height
Tenderness quartz fibre sealing ring.
Background technology
Existing high-temperature resistant seal ring mainly based on quoit, is sealed using metal high temperature resistant and deformation performance,
But metal o-ring needs to carry out custom-made according to the size actually sealed, and in closure size variation, more frequently occasion is difficult to
Its advantage is played, while there is higher manufacturing cost.To solve the above-mentioned problems, application No. is in 201510750864.X
State's invention patent discloses a kind of high-temperature resistant rubber sealing ring, which is micro- by ethylene propylene diene rubber, high wear-resistant carbon black, silicon
Powder, sulphur, accelerating agent, zinc oxide, anti-aging agent and silane coupling agent are formulated in proportion, and prepared rubber seal has
Preferable high temperature resistance.But its sealing ring starting components is complicated, manufacturing cost is also very high.
Invention content
Present invention aim to overcome the defect present in the prior art, provide it is a kind of it is simple in structure, easy to use,
High-temperature flexible quartz fibre sealing ring of low cost, performance is stable, safe and reliable.
To achieve the above object, the high-temperature flexible quartz fibre sealing ring designed by the present invention, is mainly used for high temperature ring
Sealing under the conditions of border between two abutments, it has there are one annular seal circle body in hollow structure, and special character exists
In：The annular seal circle body is docked by the head and the tail both ends of the surface sealing of a quartz fibre casing, the quartz fibre set
The hollow cavity of pipe is filled with quartzy cotton material.
Preferably, the head and the tail both ends of the surface of the quartz fibre casing are sealed by high temperature adhesive and are docked.In this way,
Its making is extremely convenient and quick.
Further, the inclined sealing docking structure of the head and the tail both ends of the surface of the quartz fibre casing.Inclined interface
Area is big, and docking is closer, and molding is more reliable.Preferably, the head and the tail both ends of the surface of the quartz fibre casing are relative to its axle center
The angle of inclination of line is 30~60 °, it is highly preferred that the angle of inclination is 45 °.
Further, the packing volume of the quartzy cotton material account for quartz fibre casing hollow cavity volume 50~
80%, preferably 60~70%.In this way it can be ensured that the volume percent content and the overwhelming majority of quartzy cotton material are by seal member
Decrement matches.
Also further, it is preferably 0.4~0.6mm that the coating layer thickness of the high temperature adhesive, which is 0.2~0.8mm,.In this way,
The dosage of high temperature adhesive can be reduced to the greatest extent on the basis of ensuring quartz fibre casing adhesive strength.
When the high-temperature flexible quartz fibre sealing ring of the specifically used present invention, quartz fibre casing can be first got out,
In the hollow cavity filling setting quality of quartz fibre casing or the quartzy cotton material of volume, then need to cut out according to use site
It is cut into suitable length, then the head and the tail both ends of the surface of quartz fibre casing are sealed by high temperature adhesive and are docked.It was verified that
The high-temperature flexible quartz fibre sealing ring of the present invention, have it is of low cost, it is with short production cycle, while decrement, seal length
Etc. parameters the advantages that being adjusted flexibly, the sealing structure that can flexibly be adapted under hot environment.
Description of the drawings
Fig. 1 is the main structure diagram of high-temperature flexible quartz fibre sealing ring of the present invention.
Fig. 2 is A-A section view enlarged structure schematic diagrams in Fig. 1.
Fig. 3 is the portions the B enlarged structure schematic diagram in Fig. 1.
Specific implementation mode
The high-temperature flexible quartz fibre sealing ring of the present invention is made below in conjunction with the drawings and specific embodiments further
Detailed description.
High-temperature flexible quartz fibre sealing ring shown in FIG. 1, be mainly used under high ambient conditions two abutments it
Between sealing, it has there are one annular seal circle body in hollow structure, and annular seal circle body is by quartz fibre casing 1
The sealing of head and the tail both ends of the surface is docked, and the hollow cavity of quartz fibre casing 1 is filled with quartzy cotton material 2 (as shown in Figure 2), stone
The packing volume of English cotton material 2 accounts for the 60~70% of 1 hollow cavity volume of quartz fibre casing.Specifically, quartz fibre casing 1
Head and the tail both ends of the surface docking (as shown in Figure 3) is sealed by high temperature adhesive 3, and the head and the tail both ends of the surface of quartz fibre casing 1 are in
Inclined seal docks, and both ends of the surface are 45 ° relative to the optimum tilt angle of its axial line at docking, high temperature adhesive 3 at docking
Best coating layer thickness be 0.4~0.6mm.Wherein quartz fibre casing 1 uses existing Type B quartz glass fibre casing,
Internal diameter 4mm or so, quartzy cotton material 2 use existing A types silica fiber material, high temperature adhesive 3 to use existing D types single group
Part room temperature curing organic silicon adhesive (Q/GHAH 47-2005).Experiments have shown that above-mentioned high-temperature flexible quartz fibre sealing ring
The continue working 30min in 1500 DEG C of hot environment, sealing are all right.
