Description
Technical field
The present invention relates to a kind of pipe line compensating device, in particular it relates to a kind of sealed roller gateway expansion joint.
Background technology
Sealed roller gateway expansion joint is mainly used in steel industry annealing furnace, is to ensure that furnace rolls system and whole set steady
Vitals.The sealed roller gateway expansion joint that current domestic sealed roller gateway is used has two kinds, and one is to use liner
The corrugated stainless steel tubing expansion joint of insulation material, owing to being limited by annealing furnace structure, this expansion joint can only compensate 20mm with
In axial displacement and the most small radial displacement, and the annealing furnace temperature of steel industry is the highest, sealed roller produce axially with
Radial displacement is 50～about 150mm, and this is extremely difficult to want for using the corrugated stainless steel tubing expansion joint on annealing furnace
Asking, under the biggest axially and radially displacement, corrugated stainless steel tubing expansion joint is often torn inefficacy, in turn results in serious thing
Therefore.Another kind is non-metal sealing roller gateway expansion joint, although can meet the radially, axially compensation needed for sealed roller uses
Amount requirement, but heat resisting temperature is relatively low, generally has that expansion joint outside wall temperature is high, easily incinerates, comes off, and leaks out, service life is short
Major defect so that range and the service life of product are restricted, therefore, import to be relied on.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, it is provided that the rapid cooling section sealed roller that a kind of novel structure, heat resistance are good goes out
Entrance expansion joint, cools down by inputting liquid nitrogen in this expansion joint, significantly improves heat-insulating property, reduces energy loss,
Significantly increase the service life.
The present invention is achieved through the following technical solutions technical goal.
Rapid cooling section sealed roller gateway expansion joint, including flange I, flange II, pressing plate I, pressing plate II, nonmetal
Textile components；Described non-metallic fabrics assembly is arranged between flange I, flange II, and pressing plate I, pressing plate II are sleeved on
On non-metallic fabrics assembly outer wall, flange I inner face, pressing plate I and flange II inner face, pressing plate II are respectively by non-gold
Belong to textile components two ends flanging to be clipped in the middle, and be bolted to connection；Described non-metallic fabrics assembly includes suit
Outer layer cydariform eyelid covering, internal layer cydariform eyelid covering；It thes improvement is that: the outer layer cydariform eyelid covering of described non-metallic fabrics assembly, interior
Layer cydariform eyelid covering two ends are tightly connected, and form the annular seal space between outer layer cydariform eyelid covering inwall, internal layer cydariform eyelid covering outer wall；Described
Outer layer cydariform eyelid covering outer wall is provided with 2 gas adapter assemblies.
In said structure, described outer layer cydariform eyelid covering, internal layer cydariform eyelid covering are multilamellar fabric.
In said structure, described non-metallic fabrics assembly two ends flanging port is respectively coated by nonmetal sealing adhesive plaster.
In said structure, in the middle part of described outer layer cydariform eyelid covering outer wall, paste reinforced cydariform eyelid covering.
In said structure, described reinforced cydariform eyelid covering is multilamellar fabric or rustless steel net.
In said structure, described outer layer cydariform eyelid covering, internal layer cydariform stressed-skin construction are identical, are all multi-layer compound structure, bag
Include the steel wire, fireproof silica gel cloth I, pottery cloth, fireproof silica gel cloth II, alkali-free glass fiber cloth, anti-the most mutually pasted
Fire silica gel cloth III；Roll on steel wire through high-temperature heating inside described fireproof silica gel cloth I；Outside described fireproof silica gel cloth I, prevent
Pottery cloth is dissolved into through high temperature inside fire silica gel cloth II；Outside described fireproof silica gel cloth II, molten through high temperature inside fireproof silica gel cloth III
Enter alkali-free glass fiber cloth.
The present invention compared with prior art, has the positive effect that:
1. the outer layer cydariform eyelid covering of non-metallic fabrics assembly, internal layer cydariform eyelid covering two ends are tightly connected, and form outer layer cydariform eyelid covering
Annular seal space between inwall, internal layer cydariform eyelid covering outer wall；Outer layer cydariform eyelid covering outer wall is provided with 2 gas adapter assemblies, liquid nitrogen
Colourless, tasteless, non-corrosiveness, non-combustible, temperature is extremely low, and the present invention inputs liquid nitrogen in annular seal space by gas adapter assembly and enters
Row cooling, serves adiabatic heat insulation effect, and greatly protection expansion joint is not corroded by high temperature, has preferable effect of heat insulation
And resistance to elevated temperatures, significantly improve the service life of sealed roller entrance expansion joint；On the other hand, heat is also substantially reduced from cydariform
Eyelid covering outwards distributes, and therefore, also substantially reduces energy loss.
2. outer layer cydariform eyelid covering, internal layer cydariform eyelid covering are multilamellar fabric, and without rigidity, without thrust, compensation dosage is big, and the life-span is long,
Convenient to install and maintain, it is particularly well-suited to that space structure is less needs again bigger axial, the occasion that radially and angularly compensates.
3. non-metallic fabrics assembly two ends flanging port is respectively coated by nonmetal sealing adhesive plaster, strengthens outer layer cydariform eyelid covering
Turning up of the sealing property of the annular seal space between inwall, internal layer cydariform eyelid covering outer wall, effectively protection non-metallic fabrics assembly two ends
Abrasion between limit and metalwork, it is to avoid non-metallic fabrics assembly two ends flanging port is by the etch of water, oil etc..
4. pasting reinforced cydariform eyelid covering in the middle part of outer layer cydariform eyelid covering outer wall, reinforced cydariform eyelid covering is multilamellar fabric or not
Rust steel mesh set, strengthens the resistance to tension of outer layer cydariform eyelid covering, significantly improves expansion joint structure intensity and bearing capacity, it is to avoid expand
Joint produces unstable phenomenon.
5. cydariform eyelid covering is composited by fireproof silica gel, pottery cloth, alkali-free glass fiber cloth etc., and fireproof silica gel is nonpoisonous and tasteless, heat
Good stability, stable chemical nature, there is higher mechanical strength；Cloth is high temperature resistant for pottery, anti-thermal shock, high-temperature insulation, nontoxic, nothing
Evil；Alkali-free glass fiber cloth good insulating, thermostability is strong, corrosion resistance good, and mechanical strength is high, therefore, the present invention significantly improve thermal insulation,
Fire prevention, antidetonation, the performance such as corrosion-resistant；Cydariform eyelid covering internal layer uses steel wire, conveniently stripped, in steel wire also ensures that expansion joint
Surface is the most directly produced spark by pipeline Gas phase Smoke to friction, shock etc., avoids mechanical damage simultaneously.
