Property and stability.
Summary of the invention
The purpose of this utility model is to provide a kind of high temperature resistant double-sealing device, which rotary can set to existing
Standby circular runout problem of expanding with heat and contract with cold makes direct compensation, to prevent gas medium leakage or extraneous gas from entering, guarantees to set
The safety of received shipment row.
Realize the technical solution taken of the utility model aim are as follows: it include seal fixing piece, seal extrusion,
Graphite packing, fastening bolt, flange, short cone cylinder, combination sealing plate, hook, flexible steel cable, fixed pulley, ballast box, flange is by tight
Fixing bolt is fixed on seal extrusion outer end, short cone cylinder and revolving body equipment escape pipe coaxial line, the big one end weldering of diameter
It connects on flange；Combination sealing plate is made of high temperature resistant thin plate, high-temperature flexible sealing plate, thin pressing plate, high-temperature flexible sealing
One section is fan-shaped plate above plate, has one section of outward bending below, the angle of bending is identical as the taper of short cone cylinder, and high temperature resistant is thin
Plate is tightly attached to high-temperature flexible sealing plate in the following, high temperature resistant thin plate upper end is concordant with high-temperature flexible sealing plate, lower end and resistance to height
The folding line of tenderness sealing plate is concordant；Thin platen shape, size are completely identical with high-temperature flexible sealing plate, are tightly attached to
Above high-temperature flexible sealing plate；One piece of block of combination sealing plate mutually laminates, and upper end is tightly attached on short cone cylinder outer wall, and by fastening
Bolt presses, lower end are tightly attached in revolving body equipment outlet pipe outer wall, form sealing surface with revolving body equipment outlet pipe outer wall；It hangs
Hook is uniformly located at the cone surface lower part formed by combination sealing plate, in revolving body equipment corresponding with highest point hook height
Escape pipe two sides, are respectively arranged with a fixed pulley, and flexible steel cable hangs over two in both ends after each hook winds with one circuit and intersects
On the fixed pulley of side two, two ballast boxes are connected to flexible steel cable both ends.
High-temperature flexible sealing plate is using carbon silicon aluminum plate semi-flexible or silicate aluminum board semi-flexible or asbestos board semi-flexible.
The beneficial effects of the utility model are: simple, the radial self-adjusting amplitude of overall structure is big, is easily installed, production side
Just, at low cost；Original make seal master and seal by compressing fastening bolt by installing radial self-reacting device additional and solving
Extrusion extruded anisotropic graphite packing is sealed, and cannot achieve the problem of automatically adjusting of expanding with heat and contract with cold, and can effectively adapt to expand with heat and contract with cold,
The drawbacks of overcoming circular runout avoids dielectric leakage and gas in cavity from entering to the full extent；Not only hindered by graphite packing
A large amount of gas, heat have been kept off, the compensation of the self-control of circular runout has been formed also by flexible sealing material, improves sealing
The sealing effect of body.
Detailed description of the invention,
It is attached that FIG. 1 is a schematic structural view of the utility model；Attached drawing 2 is the right side view of attached drawing 1；Attached drawing 3 is partial enlargement
Schematic diagram.
Specific embodiment
As shown in Figure 1, 2, it include seal fixing piece 1, it is fastening bolt 3, seal extrusion 4, graphite packing 2, tight
Fixing bolt 7, flange 5, short cone cylinder 13, combination sealing plate, hook 8, flexible steel cable 11, fixed pulley 14, ballast box 15, seal is solid
Determine part 1 to be fixedly connected with external equipment, graphite packing 2 is located at the sky formed between seal fixing piece 1 and seal extrusion 4
In, flange 5 is fixed on 4 outer end of seal extrusion, the escape pipe 6 of short cone cylinder 13 and revolving body equipment by fixing bolt 3
Coaxial line, the big one end of diameter are welded on flange 5；Combination sealing plate by high temperature resistant thin plate 12, high-temperature flexible sealing plate 10,
Thin pressing plate 9 forms, and 10 material of high-temperature flexible sealing plate is carbon silicon aluminum plate semi-flexible or silicate aluminum board semi-flexible or stone semi-flexible
Cotton plate etc., with a thickness of 6mm or so, above one section be fan-shaped plate, have one section of outward bending, the angle of bending and short cone cylinder below
13 taper is identical, and high temperature resistant thin plate 12 is tightly attached to high-temperature flexible sealing plate using 321 stainless steel materials with a thickness of 1.5mm
10 in the following, 12 upper end of high temperature resistant thin plate is concordant with high-temperature flexible sealing plate 10, and lower end is curved with high-temperature flexible sealing plate 10
Broken line is concordant, that is to say, that the appearance face contact of the escape pipe 6 of 12 lower end of high temperature resistant thin plate and revolving body equipment；Thin pressing plate 9 is adopted
With Q235B plate, with a thickness of 1.5mm, shape, size are identical with high-temperature flexible sealing plate 10, and it is soft to be tightly attached to high temperature resistant
Above property sealing plate 10；One block of block combination sealing plate mutually laminates, and upper end is tightly attached on short 13 outer wall of cone cylinder, and by fastening bolt
7 compress, and lower end is tightly attached on 6 outer wall of escape pipe of revolving body equipment, are formed and are sealed with 6 outer wall of escape pipe of revolving body equipment
