Description
Technical field
The present invention relates to graphite sealing material processing technique field, in particular to a kind of band-like carbon seal ring and its processing
Technique and process equipment.
Background technique
Sealing ring is a kind of using very extensive sealing element, and the effect of sealing ring is by sealing material for combining table
The contact pressure in face and be collectively formed interior media blocking effect is formed close of elastic-restoring force for fastening external force
Envelope, prevents the leakage of faying face.
Sealing ring is divided into metal o-ring, nonmetallic sealing ring and nonmetallic and metallic combination sealing ring, the choosing of sealing ring
With being usually to be selected according to operating pressure, operating temperature, the corrosivity of sealing medium and form in conjunction with sealing surface.It is general next
It says, in Room-temperature low-pressure, selects nonmetallic sealing ring；When middle super pressure-high temperature, nonmetallic and metallic combination sealing ring or metal are selected
Sealing ring；When temperature, pressure have larger fluctuation, select elasticity preferable or self-fastening ring；In low temperature, corrosive media
Or under vacuum condition, it is considered as the sealing ring with property.
Sealing ring made of graphite material is mostly used when high temperature typically now, high pressure sealing, the most commonly used is soft for graphite
Property expanded graphite volume, be a kind of new type functional carbon materials, be swollen through intercalation, washing, drying, high temperature by natural graphite scale
Change the loose porous vermiform substance of obtained one kind, then form coiled acquisition through dedicated press equipment, has natural stone Miboin
Other than the excellent performances such as the cold-hot of body, corrosion-resistant, self-lubricating, also there is unexistent soft, the excellent compression and back of natural graphite
The characteristics such as elastic, low creep, excellent compensatory, low leakage.Existing carbon seal ring is more the tail gas in commercial vehicle
Sealing.
To disclose a kind of superhigh-temperature and-pressure with metal retaining ring swollen for the Chinese patent that existing notification number is CN202327099U
Swollen graphite composite seal washer accompanies gold between every two layers of expanded graphite washer including two layers or more of expanded graphite washer
Belong to silk screen, and be enclosed with metal outer ring and metal inner ring retaining ring respectively in the both ends of the surface of expanded graphite washer, is used for various high temperature
Connection sealing between the equipment end construction of high pressure.
But the above-mentioned superhigh-temperature and-pressure expanded graphite composite seal washer with metal retaining ring has the disadvantage in that due to using
The mode of one metal wire layer net is set between two layers of graphite gasket, and wire mesh is plane web frame, and there are unevenly distributed
Problem, and graphite linings are easily bonded with flange in use.
In addition, in process of production, generalling use and manually carrying out braiding processing to carbon seal ring, need to expend biggish
Labour has that processing is inconvenient and production efficiency is relatively low.

Wheel 7 drives rotation axis 62 to rotate, in this way, the first driving motor 22 can drive rewinding idler wheel 7 and deviation correction mechanism 6 to be received simultaneously
Line not only more saves the energy, but also take-up fiting effect is more preferable.
Basic functional principle of the invention are as follows: when weaving to graphite coiled strip 10, choose the stone of four appropriate specifications
Black coiled strip 10 is respectively sleeved on discharging frame 21, and coiled wire is placed on silk thread rack 33, when a graphite coiled strip 10 is sent
When material, the carbon seal ring after braiding is single layer structure, the graphite grazing when multiple 10 feedings simultaneously of graphite coiled strip, after braiding
Circle is multilayered structure.Then the starting point of graphite coiled strip 10 is sequentially passed through between active extruding wheel 41 and driven nip wheel 42
Gap, material guide hole 231 and crochet hook seat 31 pass through the graphite coiled strip 10 of more strips actively during 21 unwrapping wire of discharging frame
Gap between extruding wheel 41 and driven nip wheel 42 is affixed under active extruding wheel 41 and the squeezing action of driven nip wheel 42
Tightly.The starting point of wire is passed through one of into crochet hook 32, starting driving assembly rotates turntable 34, when turntable 34 rotates
Several crochet hooks 32 successively move up and down along crochet hook seat 31, while turntable 34 drives silk thread rack 33 around circumferential turn of crochet hook seat 31
Dynamic, the outer wall that wire so can be equably knitted to strip graphite coiled strip 10 forms wire mesh 11, braiding herein
Mode is similar with the braiding of socks, specifically can refer to the patent document of Patent No. CN102677381A, herein no longer one by one
It repeats.
Graphite coiled strip 10 after woven is successively around in the side wall of directive wheel 51, driving wheel 52 and driven wheel 53, and by stone
The starting point of black coiled strip 10 is fixedly connected on rewinding idler wheel 7, and starting third driving motor 54 makes the rotation of driving wheel 52 can band
Dynamic graphite coiled strip 10 is driven, and then makes graphite coiled strip 10 in transmission process always in tensioning state, and rewinding idler wheel 7 can incite somebody to action
The graphite coiled strip 10 that braiding is completed carries out rewinding.Braiding process more rapidly and conveniently, to greatly improve work efficiency.It is receiving
In line process, the first driving motor 22 drives rotation axis 62 to rotate, and winding displacement disk 64 is made to move reciprocatingly along pedestal 61, and then can incite somebody to action
Strip graphite coiled strip 10 after braiding is equably rolled up on rewinding idler wheel 7.Deviation correction mechanism 6 is common structure, herein no longer one by one
It repeats, specific structure can refer to the patent document of Patent No. CN206720502U.
It should be noted that graphite coiled strip is the raw material for making band-like carbon seal ring, band-like carbon seal ring
It is the finished product being programmed on graphite coiled strip after wire mesh and compression moulding, and then band-like carbon seal ring is (i.e. for graphite band
