Abstract
The utility model discloses a fiber expansion joint with ring belt protective devices. The fiber expansion joint comprises ring belts, protective layers, pressing strips, upper connecting pipes, lower connecting pipes, upper annular plates, lower annular plates, pull rods and the ring belt protective devices, wherein the pull rods are fixedly connected with the upper connecting pipes and the lower connecting pipes by supports respectively; the upper annular plates are vertically and fixedly connected with the upper connecting pipes; the lower annular plates are vertically and fixedly connected with the lower connecting pipes; the upper ends of the lower connecting pipes extend into the upper connecting pipes; two ends of the ring belts are fixed to the upper annular plates and the lower annular plates by the pressing strips; the upper connecting pipes, the lower connecting pipes, the upper annular plates, the lower annular plates and the ring belts form the insolating layers; and the ring belt protective devices are fixed to the surfaces of the ring belts by the pressing strips. According to the fiber expansion joint, a layer of metal mesh is fixedly arranged outside each ring belt, and can protect the ring belts of the fiber expansion joint from not being abraded in the hoisting and transportation processes, so that the service life of the ring belts of the fiber expansion joint is prolonged.
Description
Technical field
The utility model 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.
The model utility content
The utility model technical problem to be solved 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 utility model 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 utility model, said astragal protective gear is wire netting or sheet metal.
As the further improved technological scheme of the utility model, said astragal protective gear is a wire netting.
As the further improved technological scheme of the utility model, said astragal protective gear is a steel wire.
The utility model is installed 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.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Further specify below in conjunction with the embodiment of accompanying drawing the utility model.
Embodiment
Embodiment 1
Referring to Fig. 1, the filament expansion of this zone circle band protective gear joint comprises astragal 1, thermal insulation layer 2, press strip 3, upper connecting tube 4, lower linking tube 5, upper ring plate 6, lower ring plate 7 and pull bar 8; Pull bar 8 is fixedly connected with upper connecting tube 4, lower linking tube 5 respectively through support, and upper ring plate 6 is connected with upper connecting tube 4 vertical fixing, and lower ring plate 7 is connected with lower linking tube 5 vertical fixing; The upper end of lower linking tube 5 is stretched in the upper connecting tube 4, and astragal 1 both sides are fixed on upper ring plate 6 and the lower ring plate 7 by press strip 3 respectively, connect mutually between upper connecting tube 4, lower linking tube 5, upper ring plate 6, lower ring plate 7 and the astragal 1; Cavity of middle formation is filled with filler in the cavity, this filling space is thermal insulation layer 2; In astragal 1 mounted on surface steel wire 9 is arranged; Chain link fence 9 is rolled in astragal 1 outside, and the edge is fixed up by press strip 3, and astragal 1 is not directly contacted with the outside; When lifting and transportation, be not worn, thereby prolong its working life.
