Abstract
The utility model discloses a totally-sealed wear-resistant fiber expansion joint, which comprises ring belts, heat-insulating layers, pressing strips, upper connecting pipes, lower connecting pipes, upper annular plates, lower annular plates and pull rods, 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 in a sealed mode; the upper connecting pipes, the lower connecting pipes, the upper annular plates, the lower annular plates and the ring belts form the heat-insulating layers; and ceramic layers are arranged on inner wall surfaces of the upper connecting pipes and the lower connecting pipes. According to the totally-sealed wear-resistant fiber expansion joint, the ring belts wraps outside the heat-insulating layers in a totally-sealed mode and can protect the heat-insulating layers inside the ring belts better, so that the heat-insulating layers are freed from chemical corrosion from the outside and pipelines, and the service life of the fiber expansion joint is prolonged; and the ceramic layers arranged on the inner side of a diversion pipe have wear-resistant and corrosion-resistant effects, so that the service life of the fiber expansion joint can be prolonged.
Description
Technical field
The utility model relates to a kind of expansion joint, particularly a kind of non-metal expansion joint.
Background technique
The filament expansion joint can provide bigger multidirectional compensation rate on less axial mounting distance; Can effectively eliminate simultaneously the installation integrating error of whole system; So extensively adopted; 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.Traditional filament expansion pitch circle band is open type often, when the big pipeline of inleakage uses, can lower blast like this, but because seal, cause the corrosion of base insulating layer easily, the working life of reduction expansion joint; And expansion joint is in use, can easy abrasion, and especially under the condition of high temperature, the process of regular experience rising-heat contracting-cold, it is especially serious to wear and tear, and this has had a strong impact on the life-span of expansion joint.
The model utility content
The utility model technical problem to be solved provides a kind of all-sealed abrasion resistant fibrous expansion joint that the little pipeline of inleakage uses that is adapted at.
For solving the problems of the technologies described above; The technological scheme that the utility model adopted is: a kind of all-sealed abrasion resistant fibrous expansion joint; Comprise 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, and upper ring plate is connected with the upper connecting tube vertical fixing; Lower ring plate is connected with the lower linking tube vertical fixing; The upper end of lower linking tube is stretched in the upper connecting tube, the astragal both sides respectively by the press strip sealing and fixing on upper ring plate and lower ring plate, be thermal insulation layer between upper connecting tube, lower linking tube, upper ring plate, lower ring plate and the astragal; The internal face of upper connecting tube and lower linking tube is provided with ceramic layer.
As the further improved technological scheme of the utility model, said astragal material is that ethylene propylene diene rubber applies glass cloth.
The all-sealed thermal insulation layer outside that is wrapped in of the astragal of the all-sealed abrasion resistant fibrous expansion joint of the utility model; Be applicable to the pipeline that inleakage is little; Compare the open type astragal and have the thermal insulation layer that to protect inside; Make it avoid prolonging the working life of filament expansion joint from the chemical corrosion in outside and the pipeline; It is soft that the ethylene propylene diene rubber of selecting for use applies glass cloth performance, can absorb the displacement amount from each side; The ceramic layer that set up the honeycomb duct inboard has the wear resistant corrosion resistant effect, can prolong the working life of expansion joint.
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, this all-sealed abrasion resistant fibrous expansion 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; Astragal 1 both sides respectively by press strip 3 sealing and fixing on upper ring plate 6 and lower ring plate 7, promptly press strip 3 is tightly connected with upper ring plate 6 and lower ring plate 7, connects 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; Be filled with filler in the cavity, this filling space is thermal insulation layer 2, and the material that astragal 1 is selected for use is that ethylene propylene diene rubber applies glass cloth; Internal face at upper connecting tube 4 and lower linking tube 5 posts one deck pottery, is ceramic layer 9; This all-sealed abrasion resistant fibrous expansion joint is adapted at the little pipeline of inleakage and uses, and compares the open type astragal and has the thermal insulation layer that can better protect inside, makes it avoid prolonging the working life of filament expansion joint from the chemical corrosion in outside and the pipeline; It is soft that the ethylene propylene diene rubber of selecting for use applies glass cloth performance, can absorb the displacement amount from each side; The ceramic layer that set up the honeycomb duct inboard has the wear resistant corrosion resistant effect, can prolong the working life of expansion joint.
