Abstract
The invention discloses a kind of High-temp. kiln dynamic seal structures, structure design is suitable for chemical industry high-temperature field High Temperature Rotating stove dynamic sealing industry, and the composition of structure is made of dynamic rotary part, static fixing piece, sealed packing, compression retaining ring, pressurising elastomeric bladder and cooling pressure pumping plant.Enter pressurising elastomeric bladder by cooling pressure pumping plant conveying high-pressure cooling medium, so that it is expanded against compression retaining ring and apply pressure to sealed packing, realizes sealing effect, can both complete dynamic sealing, the liquid of pressure pumping plant is cooling medium simultaneously, is not affected by high temperatures sealing.
Description
Technical field
A kind of High-temp. kiln dynamic seal structure of the present invention belongs to the dynamic of chemical industry, mine and oil field stove equipment
Seal industry, and in particular to a kind of thermal technology's stove docking dynamic seal structure form.
Background technique
For a long time, the Butt sealing problem of high temperature equipment annoyings always engineering personnel, the sealing of High-temp. kiln
Mechanical seal and high temperature resistant elastomer seal are generallyd use, but machinery sealing material suffers from high-temperature heat expansion influence,
It will lead to seal failure or effect decaying, cause leakage accident；Sealing material uses elastomer seal, although solving sealing
Thermal expansion problem, high sealing material cause influence to production cost again.This technology is designed in absorption conventional seals
On the basis of, its advantage and disadvantage are summarized, hydraulic technique and cooling technology are merged.
Summary of the invention
It is an object of the invention to overcome the above-mentioned prior art insufficient, a kind of High-temp. kiln dynamic seal structure is provided, is solved
Determined elevated-temperature seal characteristic supplement, realize the sealing problem under high temperature dynamic.
The technical scheme is that solve in this way:
A kind of High-temp. kiln dynamic seal structure, including static fixing piece, dynamic rotary part, sealed packing, compress retaining ring,
Pressurising elastomeric bladder and cooling pressure pumping plant, static fixing piece and dynamic rotary part junction set gradually sealed packing,
Retaining ring and pressurising elastomeric bladder are compressed, pressurising elastomeric bladder, which is inlayed, to be fixed on sealing cover, and sealing cover is fixed by screws in static solid
Determine on part, the inlet and liquid outlet being arranged on sealing cover, is connect by pipeline with cooling pressure pumping plant, in the pipeline of liquid outlet
On be provided with counterbalance valve and be provided with flow valve on the pipeline of inlet, pass through and adjust counterbalance valve and flow valve controls punching press elasticity
The contraction or expansion of capsule.
Pressurising elastomeric bladder is made of cyclic spring utricule and n filling liquid nozzle, and filling liquid nozzle is arranged in cyclic spring utricule side,
It is fixed on sealing cover in symmetric arrays, cyclic spring utricule is rectangle, ellipse or trapezoidal sectional shape.
Cooling pressure pumping plant is made of counterbalance valve, pressure pump and liquid circulation pond, and back is provided on the pipeline of liquid outlet
Pressure valve is provided with flow valve on the pipeline of inlet.
The present invention has following beneficial technical effect:
The present invention utilizes hydraulic principle and liquid cooling principle, and invention is supplied to sealing position liquid by cooling pressure pumping plant
Body pressurising elastic pressure and refrigerating function, sealing position by high temperature and thermal expansion influence, do not make the various pieces of sealing structure exist
Under hydraulic action, optimal seal effects are remained.The Butt sealing material for solving conventional high-temperature equipment suffers from
High-temperature heat expansion influences, the not foot phenomenon for causing seal failure or effect to decay.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Fig. 2 is pressurising elastomeric bladder structural schematic diagram of the present invention；
Specific embodiment
A kind of High-temp. kiln dynamic seal structure, the structure by static fixing piece, dynamic rotary part, sealed packing,
Retaining ring, pressurising elastomeric bladder and cooling pressure pumping plant composition are compressed, is successively set in static fixing piece and dynamic rotary part junction
It set sealed packing, compressed retaining ring and pressurising elastomeric bladder, pressurising elastomeric bladder, which is inlayed, to be fixed on sealing cover, and sealing cover passes through screw
It is fixed on static fixing piece, the inlet and liquid outlet being arranged on sealing cover, is connect by pipeline with cooling pressure pumping plant,
It is provided with counterbalance valve on the pipeline of liquid outlet and is provided with flow valve on the pipeline of inlet, by adjusting counterbalance valve and flow
Valve realizes pressure and flow adjustment.
Referring to shown in attached drawing, the present invention proposes a kind of High-temp. kiln dynamic seal structure, first in static fixing piece 1 and dynamic
2 junction of state revolving part has set gradually sealed packing 3, has compressed retaining ring 4 and pressurising elastomeric bladder 5, and pressurising elastomeric bladder 5 is inlayed solid
It is scheduled on sealing cover 7, pressurising elastomeric bladder 5 is connected to by filling liquid nozzle 12 with the inlet 6 of sealing cover 7 and liquid outlet 8, through piping
It is connect respectively with the pressure pump 11 of cooling pressure pumping plant 9 and liquid circulation pond 14, is provided with counterbalance valve on the pipeline of liquid outlet 8
10 are provided with flow valve 15 on the pipeline of inlet 6.
The 11 output pressure liquid medium of pressure pump of cooling pressure pumping plant 9 passes through flow valve 15, connecting pipe, inlet 6
It gives pressurising elastomeric bladder 5 filling liquid, expands pressurising elastomeric bladder 5, push and compress 4 compression seal packing 3 of retaining ring, realize sealing effect,
The heating liquid medium of pressurising elastomeric bladder 5 flows back into the heat dissipation of liquid circulation pond 14 by liquid outlet 8, connecting pipe and counterbalance valve 10
After be recycled, form elevated-temperature seal and sealing position cooling effect；Structure is realized by adjusting counterbalance valve 10 and flow valve 15
Adjust the flow of cooling pressure medium and the effect of pressure.
