Abstract
The invention discloses a high-temperature-resisting flexible quartz fiber sealing ring which is mainly applied to sealing of two leaning components under a high-temperature environmental condition. The high-temperature-resisting flexible quartz fiber sealing ring comprises a ring-like sealing ring body which is of a hollow structure, and is specially characterized in that the ring-like sealing ring body is formed by hermetically butting the end face of the head end and the end face of the tail end of one quartz fiber sleeve; and a hollow part of the quartz fiber sleeve is filled with a quartz wool material. Preferably, the end faces of the head end and the tail end of the quartz fiber sleeve are hermetically butted with each other by using a high-temperature adhesive. Furthermore, the end faces of the head end and the tail end of the quartz fiber sleeve form an inclined hermetically-butted structure. The high-temperature-resisting flexible quartz fiber sealing ring is simple in structure, convenient to use and low in cost, can be used for replacing a traditional metal sealing ring, and can fully play the advantages at a situation that the sealing dimension is changed frequently.
Description
Technical field
The present invention relates to the fast sealing mounting technology between hot environment lower component and part, in particular to a kind of resistance to height
Tenderness quartz fibre sealing ring.
Background technology
Existing high-temperature resistant seal ring is mainly based on quoit, high temperature resistant and deformation performance is sealed using metal,
But metal o-ring needs to carry out custom-made according to the size of actual sealing, and in closure size change, more frequently occasion is difficult to
Play its advantage, there is higher manufacturing cost simultaneously.In order to solve the above problems, in Application No. 201510750864.X
State's patent of invention discloses a kind of high-temperature resistant rubber sealing ring, and this sealing ring is micro- by ethylene propylene diene rubber, high wear-resistant carbon black, silicon
Powder, sulfur, accelerator, zinc oxide, age resistor and silane coupler are formulated in proportion, and prepared rubber seal has
Preferably resistance to elevated temperatures.But its sealing ring starting components is complicated, manufacturing cost is also very high.
Content of the invention
Present invention aim to overcoming the defect existing for prior art, provide a kind of structure simple, easy to use,
With low cost, stable performance, safe and reliable high-temperature flexible quartz fibre sealing ring.
For achieving the above object, the high-temperature flexible quartz fibre sealing ring designed by the present invention, is mainly used in high temperature ring
Sealing between two abutment under the conditions of border, it has an annular seal circle body in hollow structure, and its special character exists
In：Described annular seal circle body is formed by the head and the tail two ends face seal docking of a quartz fibre sleeve pipe, described 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 described quartz fibre sleeve pipe seal docking by high temperature adhesive.So,
It is quick that it makes extremely convenient.
Further, the head and the tail both ends of the surface inclined sealing docking structure of described quartz fibre sleeve pipe.The interface tilting
Area is big, and docking is tightr, and molding is more reliable.Preferably, the head and the tail both ends of the surface of described quartz fibre sleeve pipe are with respect to its axle center
The angle of inclination of line is 30～60 °, it is highly preferred that described angle of inclination is 45 °.
Further, described quartz cotton material packing volume account for quartz fibre sleeve pipe hollow cavity volume 50～
80%, preferably 60～70%.In this way it can be ensured that the volume percent content of quartzy cotton material and the overwhelming majority are by seal member
Decrement matches.
Also further, the coating layer thickness of described high temperature adhesive is that 0.2～0.8mm is preferably 0.4～0.6mm.So,
The consumption of high temperature adhesive on the basis of guaranteeing quartz fibre sleeve pipe adhesive strength, can be reduced as far as possible.
During the high-temperature flexible quartz fibre sealing ring of the specifically used present invention, can first get out quartz fibre sleeve pipe,
Set the quartzy cotton material of quality or volume in the hollow cavity filling of quartz fibre sleeve pipe, then need to cut out according to using scene
It is cut into suitable length, then the head and the tail both ends of the surface of quartz fibre sleeve pipe are docked by high temperature adhesive sealing.It was verified that
The high-temperature flexible quartz fibre sealing ring of the present invention, has with low cost, with short production cycle, decrement, seal length simultaneously
The advantages of can be adjusted flexibly etc. parameter, can flexibly be adapted to the sealing structure under hot environment.
