Abstract
The invention discloses a full-sealed fiber expansion joint, which comprises a strap, heat-insulation layers, depression bars, an upper connecting pipe, a lower connecting pipe, an upper annular plate, a lower annular plate, a draw bar and strap protecting devices. The draw bar is respectively fixedly connected with the upper connecting pipe and the lower connecting pipe by supports, the upper annular plate is perpendicularly fixedly connected with the upper connecting pipe, the lower annular plate is perpendicularly fixedly connected with the lower connecting pipe, the upper end of the lower connecting pipe extends into the upper connecting pipe, two sides of the strap are respectively fixed onto the upper annular plate and the lower annular plate by the depression bars, the heat-insulation layers are disposed among the upper connecting pipe, the lower connecting pipe, the upper annular plate, the lower annular plate and the strap, and the strap protecting devices are fixed to the surface of the strap by the decompression bars. A metal screen is fixedly mounted on the outside of the strap of the fiber expansion joint, the strap of the fiber expansion joint can be protected when the fiber expansion joint is hoisted and transported, and cannot be abraded easily, and accordingly the service life of the strap of the fiber expansion joint is prolonged.
Description
Technical field
The present invention relates to a kind of expansion joint, particularly a kind of filament expansion joint.
Background technique
Expansion joint is the additional stress that causes because of temperature difference and mechanical vibration in order to compensate, and is arranged on a kind of flexible structure on container shell or the pipeline.Because it is as a kind of elastic compensating element that can freely stretch, advantages such as reliable operation, functional, compact structure have been widely used in departments such as chemical industry, metallurgy, nuclear energy.The filament expansion joint can provide bigger multidirectional compensation rate on less axial mounting distance, can effectively eliminate the installation integrating error of whole system simultaneously, than traditional expansion of metal joint the better application prospect is arranged.Filament expansion pitch circle band covers outside the thermal insulation layer, and main effect is to bear flue gas system pressure and from flue gas and extraneous chemical corrosion, protect thermal insulation layer.Because filament expansion pitch circle band is generally made with rubber material, easy abrasion under the situation of repeatedly lifting transportation reduces its working life.
Summary of the invention
Technical problem to be solved by this invention is the deficiency to above-mentioned existing technology, and a kind of filament expansion joint of zone circle band protective gear is provided.
For solving the problems of the technologies described above, the technological scheme that the present invention adopted is: a kind of all-sealed filament expansion joint comprises astragal, thermal insulation layer, press strip, upper connecting tube, lower linking tube, upper ring plate, lower ring plate and pull bar; Pull bar is fixedly connected with upper connecting tube, lower linking tube respectively through support; Upper ring plate is connected with the upper connecting tube vertical fixing, and lower ring plate is connected with the lower linking tube vertical fixing, and the upper end of lower linking tube is stretched in the upper connecting tube; The astragal both sides are fixed on upper ring plate and the lower ring plate by press strip respectively; Be thermal insulation layer between upper connecting tube, lower linking tube, upper ring plate, lower ring plate and the astragal, also comprise the astragal protective gear, the astragal protective gear is fixed on the astragal surface by press strip.
As the further improved technological scheme of the present invention, said astragal protective gear is wire netting or sheet metal.
As the further improved technological scheme of the present invention, said astragal protective gear is a wire netting.
As the further improved technological scheme of the present invention, said astragal protective gear is a steel wire.
The present invention installs the layer of metal net in the fixed outside of filament expansion pitch circle band, can in the process of lifting and transportation, protect filament expansion pitch circle band, makes it be difficult for being worn, thereby prolongs the working life of filament expansion pitch circle band.
