Description
Technical field
This utility model relates to a kind of graphiote reactor field, seals structure particularly to a kind of graphite upper cover.
Background technology
Graphiote reactor has good heat-resisting quantity, heat conductivity, lubricity, chemical stability, plasticity, thermal shock resistance
Deng, it being able to take the acute variation of temperature when graphite uses at normal temperatures and will not destroy, during temperature jump, the volume of graphite becomes
Change little, will not crack, therefore in a lot of reactions all using graphite as the material making reactor, but graphite is strong
Spending the highest, the outer layer at graphiote reactor usually needs to make one layer of steel construction crust, in the upper end of graphiote reactor be also as
This, the upper end on graphiote reactor needs to connect a shaft, and the seal request of junction is the highest, and current technology is the completeest
Kind.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of good seal performance, and the graphite upper cover of simple in construction is close
Seal structure.
For solving above-mentioned technical problem, the technical solution of the utility model is: a kind of graphite upper cover seals structure, its wound
New point is: include upper cover, upper cover plate, adapter, packing ring and mechanical seal；Described upper cover center has a circular hole A,
Described circular hole A upper end has the annular table terrace of a sinking, and described adapter is plugged in annular table terrace, forms one with circular hole A
Upper and lower isodiametric poke hole, has a step surface coordinated with upper cover upper surface outside this adapter；Described upper cover plate is arranged
In upper cover upper surface, having a pad between the two, this upper cover plate center has the circular hole B of a receiving adapter；Described machine
Tool seals has a packing ring between adapter.
Further, described washer inner surface coordinates with shaft, and outer surface bottom coordinates with upper cover plate.
Further, there is a briquetting between described packing ring and mechanical seal.
Further, described adapter and packing ring, packing ring all has pad on the contact surface of briquetting.
The utility model has the advantage of:
1) this utility model one graphite upper cover seals structure, simple in construction, and sealing is strong, has considered on graphite
End socket and the material properties of steel construction upper cover plate, take over as graphite material, and packing ring is steel structure material, ingenious utilizes graphite portion
Part and the stacking of steelwork component, it is ensured that graphite and the sealing of steel construction joining place；
2) during its lower part divides the circular hole B being plugged on upper cover plate, Convenient pad delineation position；
3) general packing ring is all the standard component that thickness is certain, is not fine with the sealing of mechanical seal, and briquetting is permissible
Processing as requested, the sealing relationship between mechanical seal and packing ring is good；
4) graphite material and steel structure material are all the materials that toughness is bad, have had the buffering of pad, good airproof performance.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that this utility model a kind of graphite upper cover seals structure.
Detailed description of the invention
As it is shown in figure 1, the utility model discloses a kind of graphite upper cover to seal structure, including upper cover 1, upper cover plate 6,
Adapter 5, packing ring 3 and mechanical seal 4；Upper cover 1 center has a circular hole A, and circular hole A upper end has the annular table of a sinking
Terrace, adapter 5 is plugged in annular table terrace, forms about one isodiametric poke hole with circular hole A, has outside this adapter 5
One step surface coordinated with upper cover 1 upper surface；Upper cover plate 6 is arranged on upper cover 1 upper surface, has a pad 7 between the two,
This upper cover plate 6 center has the circular hole B of a receiving adapter 5；There is between mechanical seal 4 and adapter 5 packing ring 3；In packing ring 3
Surface coordinates with shaft, and outer surface bottom coordinates with upper cover plate 6；There is between packing ring 3 and mechanical seal 4 briquetting 2；Adapter
5 all have pad with packing ring 3, packing ring 3 on the contact surface of briquetting 2.
Upper cover 1 is graphite with the material of adapter 5, and packing ring 3 is Steel material with the material of briquetting 2, adapter 5 and upper cover 1
Step surface seals and coordinates, and its inner surface leaves certain space with the rigidity shaft in poke hole, and packing ring 3 is arranged on adapter 5
Upper end, is buffered by pad 7, is compressed between the two, and packing ring 3 lower part is positioned at the circular hole B of upper cover plate 6, it is simple to location, packing ring
The inner surface of 3 coordinates with shaft, and packing ring 3 upper end has briquetting 2, has pad buffering between the two, and briquetting 2 can regard concrete
Mated condition be processed manufacture, it is simple to filling machine seal 4 and packing ring 3 between space.
Of the present utility model ultimate principle and principal character have more than been shown and described.The technical staff of the industry should
Solving, this utility model is not restricted to the described embodiments, and simply illustrates that this practicality is newly described in above-described embodiment and description
The principle of type, on the premise of without departing from this utility model spirit and scope, this utility model also has various changes and modifications,
In the range of these changes and improvements both fall within claimed this utility model.This utility model claims scope by appended
Claims and equivalent thereof define.
