Abstract
The invention discloses a high-temperature-resistant non-metallic expansion joint. The high-temperature-resistant non-metallic expansion joint comprises flanges and drum-shaped skin, wherein the flanges are fixedly connected to two ends of the drum-shaped skin to form a compensation structure; spigots are formed in inner end surfaces of the flanges; two ends of the drum-shaped skin are turned outwards to form radial flange sides; the radial flange sides are embedded into the spigots in the inner end surfaces of the flanges; ring-shaped plates are arranged on the inner end surfaces of the flanges and are fixedly connected to the inner end surfaces of the flanges via bolts; the radial flange sides of the drum-shaped skin are fixedly connected to the spigots in the inner end surfaces of the flanges; the further improvement of the high-temperature-resistant non-metallic expansion joint is characterized in that gaps between the ring-shaped plates and the inner end surfaces of the flanges are filled with sealants to form a spigot periphery sealing structure; the drum-shaped skin is a multilayer composite structure; steel wire meshes are single-layer or multilayer metal wire meshes. Through the high-temperature-resistant non-metallic expansion joint, the flanges are reliably connected to the two ends of the drum-shaped skin; the expansion joint has resistance to high temperature, heat insulation, fire resistance, vibration resistance and corrosion resistance.
Description
Technical field
The present invention relates to pipe line compensating device, particularly relate to a kind of steel industry annealing furnace non-metal expansion joint.
Background technology
Furnace roller expansion joint is mainly used in steel industry annealing furnace, is to ensure that furnace rolls system and the vitals of whole set steady, present steel industry annealing furnace typically use non-metal expansion joint.Existing non-metal expansion joint includes flange, cydariform eyelid covering, and flange is connected to the two ends of cydariform eyelid covering by glue, constitutes collocation structure, this non-metal expansion joint simple in construction, but flange is connected by glue with cydariform eyelid covering two ends, disengaging after easy degumming, it is unreliable to connect.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of high temperature resistant non-metal expansion joint that flange can be made to be reliably connected with cydariform eyelid covering two ends, this non-metal expansion joint has preferable resistance to elevated temperatures.
The present invention is achieved through the following technical solutions technical goal.
High temperature resistant non-metal expansion joint, including flange, cydariform eyelid covering, described flange is fixedly connected on the two ends of cydariform eyelid covering, constitutes collocation structure；It thes improvement is that: described flange inner face is provided with seam, turns up in cydariform eyelid covering two ends, forms radial flange limit, embeds in flange inner face seam；Described flange inner face is provided with ring flat-plate, and ring flat-plate is fixedly connected on flange inner face by screw, and is fixedly connected in flange inner face seam on cydariform eyelid covering radial flange limit.
In said structure, filling with sealant in gap between described ring flat-plate and flange inner face, form seam perimeter seal.
In said structure, described cydariform eyelid covering is multi-layer compound structure, including the steel wire the most mutually pasted, fireproof silica gel I, pottery cloth I, fireproof silica gel II, pottery cloth II, fireproof silica gel III；Roll on steel wire through high-temperature heating inside described fireproof silica gel I；Pottery cloth I is dissolved into through high temperature outside described fireproof silica gel I, inside fireproof silica gel II；Pottery cloth II is dissolved into through high temperature outside described fireproof silica gel II, inside fireproof silica gel III.
In said structure, described steel wire is single or multiple lift metal gauze.
The present invention compared with prior art, has the positive effect that:
1, by ring flat-plate, cydariform eyelid covering radial flange limit is fixedly connected in flange inner face seam, flange can be made to be reliably connected with cydariform eyelid covering two ends.
2, filling with sealant in gap between ring flat-plate and flange inner face, forms seam perimeter seal, makes cydariform eyelid covering radial flange limit be in the seam of sealing, can avoid the etch to cydariform eyelid covering radial flange limit such as oil, water.
3, cydariform eyelid covering is composited by fireproof silica gel, pottery cloth etc., and fireproof silica gel is nonpoisonous and tasteless, Heat stability is good, stable chemical nature, can bear and higher uses pressure, has higher mechanical strength；Cloth is high temperature resistant for pottery, anti-thermal shock, high-temperature insulation, nontoxic, harmless；Therefore, the method can significantly improve thermal insulation, fire prevention, antidetonation, the performance such as corrosion-resistant, high temperature resistant.
4, cydariform eyelid covering internal layer uses steel wire, and conveniently stripped, steel wire also ensures that expansion joint inner surface is the most directly produced spark by tunnel gas Relative friction, shock etc., avoids mechanical damage simultaneously.
