Abstract
The utility model discloses an axial internal pressure type ceramic wear-resistant expansion joint which comprises a corrugated pipe, a ceramic flow guide cylinder is sheathed in the corrugated pipe,a left connecting pipe is fixedly arranged at the left end of the corrugated pipe, the left connecting pipe is fixed on the ceramic flow guide cylinder, and a right connecting pipe is fixedly arrangedat the right end of the corrugated pipe. The axial internal pressure type ceramic wear-resistant expansion joint adopts the ceramic flow guide cylinder, when the expansion joint is refrigerated, thecorrugated pipe contracts to the left relative to the ceramic flow guide cylinder, when the expansion joint is heated, the corrugated pipe expands to the right and extends to the right relative to theceramic, therefore, due to the different thermal expansion and contraction performances between the corrugated pipe and the ceramic flow guide cylinder, when the expansion joint is heated or refrigerated, the corrugated pipe extends or contracts to the right relative to the flow guide cylinder; and due to good wear-resistant performance of ceramic materials and strong corrosion resistance, the wear-resistant problem of the expansion joint is fundamentally solved, thereby reducing system outage or pipeline overhaul time caused by replacement of the expansion joint and effectively improving theoperation and working efficiency of a pipeline.
Description
Technical field
The utility model relates to a kind of expansion joint, relates to a kind of assurance line transportation safety specifically, the wear-resisting expansion joint of axialmode internal pressure type of a kind of flexible compensation that installs additional on pipeline.
Background technique
Expansion joint is the critical component of pressure piping, in the Pneumatic conveying pipeline system, its effect is particularly important, but existing expansion joint all makes with stainless steel material, under the industrial and mineral condition of mean velocity 40m/s, wear-resistingly become a main difficult problem, the material complex chemical composition of carrying, corrosion-resistant also is major issue, existing expansion joint can not satisfy the production needs, it is too high to cause expansion joint to change frequency, has had a strong impact on the normal operation of pipeline.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned deficiency a kind of axialmode internal pressure type ceramic wear-resisting expansion joint is provided, and has solved the technical problem that expansion joint wears no resistance.
The technical solution of the utility model is:
A kind of axialmode internal pressure type ceramic wear-resisting expansion joint, comprise bellows, the ceramic guide shell of cover in bellows, at the fixing left connecting tube of bellows left end, left side connecting tube is fixed on the ceramic guide shell, at the fixing right connecting tube of the right-hand member of bellows, so ceramic guide shell and bellows left end are fixed, when bellows is heated or catches a cold ceramic relatively guide shell can about stretch.
Above-mentioned axialmode internal pressure type ceramic wear-resisting expansion joint is provided with pressing plate at the left end of ceramic guide shell, at right connecting tube right-hand member wear ring is set.
Above-mentioned axialmode internal pressure type ceramic wear-resisting expansion joint, left connecting tube and right connecting tube are fixed with flange respectively.
Above-mentioned axialmode internal pressure type ceramic wear-resisting expansion joint is provided with pull bar between described two flanges.
Above-mentioned axialmode internal pressure type ceramic wear-resisting expansion joint, described ceramic guide shell is the wear-resisting alumina ceramic guide shell.
The utility model is owing to adopt ceramic guide shell, when expansion joint is caught a cold, the ceramic relatively guide shell of bellows shrinks left, bellows expands to the right when being heated, bellows pottery relatively stretches out to the right, like this because bellows is different with the performance of expanding with heat and contract with cold of ceramic guide shell, the ceramic relatively guide shell of bellows is flexible to the right when being heated or catching a cold, because the wear-resisting property of stupalith is good, and corrosion resistance is strong, has so fundamentally solved the wear-resisting problem of expansion joint, reduced owing to changing system's stoppage in transit or the pipeline overhaul time that expansion joint causes, effectively improved pipeline operation working efficiency.At the wear ring that the right-hand member of connecting tube is provided with, can be multi-faceted wear-resisting, increase the working life of expansion joint, saved cost.The utility model can compensate extraction duct axially, laterally, the angle thermal distortion, the absorption equipment vibration reduces the influence of vibration equipment to pipeline, can also absorb earthquake, the earth subsidence amount of deformation to pipeline.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the topology view of the utility model flange;
Fig. 3 is Fig. 2 A-A sectional view.
Embodiment
As Fig. 1, Fig. 2 and a kind of axialmode internal pressure type ceramic wear-resisting expansion joint shown in Figure 3, comprise bellows 1, the ceramic guide shell 2 of cover in bellows 1, at the fixing left connecting tube 3 of bellows 1 left end, left side connecting tube 3 is fixed on the left end of ceramic guide shell 2, at the fixing right connecting tube 4 of the right-hand member of bellows 1, so ceramic guide shell 2 is fixed with bellows 1 left end, when bellows 1 is heated or catches a cold ceramic relatively guide shell 2 can about flexible, left end at ceramic guide shell 2 is provided with pressing plate 6, right-hand member at ceramic guide shell 2 is provided with wear ring 5, left side connecting tube 3 and right connecting tube 4 be fastening flange 7 respectively, 8, between described two flanges pull bar 9 is set, ceramic guide shell 2 is wear-resisting alumina ceramic guide shells.
Working procedure: the utility model is installed on the pipeline, when the fluid heats of carrying, the ceramic relatively guide shell elongation of bellows, when liquid turns cold, the ceramic relatively guide shell of bellows shortens, because ceramic guide shell and bellows are that an end is fixed, can guarantee that the ceramic relatively guide shell of bellows makes fore and aft motion.
