Abstract
The utility model relates to a composite abrasion-resistant and pressure-resistant pipeline which is formed by an outer pipe used for pressure bearing and made of anti-corrosion steel pipes, glass steel pipes or enhancement plastic pipes, and an inner pipe made of abrasion-resistant material in a composite mode, wherein the inner pipe is a whole segment of pipe, expansion gaps are reserved between the inner pipe and the outer pipe and in the longitudinal direction of the inner pipe, and an moving-stopping device for preventing the inner pipe from sliding and moving longitudinally is arranged at the end of the pipeline. Due to the expansion gaps between the inner pipe and the outer pipe and in the longitudinal direction of the inner pipe and an expansion compensation groove in a blocking ring, the space between the inner pipe and the outer pipe and the inner pipe both can expand freely, the relative expansion and shrinking problem generated because of no-gap compositing between the inner pipe and outer pipe is thoroughly solved, and meanwhile the inner pipe can be assembled and maintained on site more easily.
Description
Affiliated technical field
The present invention relates to a kind of by the abrasiveness medium transport pipeline wear-resisting, pressure-resistant material is composited.
Background technique
At present, the abrasiveness medium transport pipeline in actual use is multiple tube or single wear resistance engineering plastics pipe and the reinforcement reinforced composite pipe roads thereof such as steel one plastics or rubber, steel-pottery or cast stone mostly.Their most wear resistancies are not enough, cost performance is not high, or do not have good wear-resisting withstand voltage properties concurrently, or the interface combination between the different materials of its multiple tube and the thoroughly solution of relative expansion problem, can not meet usage requirement completely.
Summary of the invention
Not enough in order to overcome the wear resistance of all kinds of abrasiveness medium transport pipelines, or do not have wear-resisting withstand voltage properties concurrently, or multiple tube interface in conjunction with and the shortcoming such as relative expansion, the present invention adopts following scheme:
Abrasiveness medium transport piping design is become to not only wear-resisting but also withstand voltage multiple tube, the inner tube that the outer tube being served as by the steel pipe in order to pressure-bearing, Glass Steel Tube or reinforced plastic pipe and high-abrasive material are made is composited, it is characterized in that inner tube is one section of homogeneous tube, between inner and outer pipes and inner tube longitudinally leave clearance for expansion, end is provided with the only moving device that prevents inner tube straight skidding.For stoping abrasiveness particle to enter inner and outer pipes gap, wash away outer tube wall, in inner and outer pipes interlayer, fill out with elastic material, this elastic material is elaxtic seal or elasticity filtering material.Preservative treatment should be done in steel outer tube wall and end.Inner tube is born wear-resisting functions like this, and outer tube is due to no longer frayed and only bear proof to external pressure and interior compression functions, thereby can bring into play material property advantage separately.Simultaneously due between inner and outer pipes and inner tube longitudinally have clearance for expansion, completely freely relative expansion between inner and outer pipes, and inner tube itself also can free expansion, thus problem is shunk in the relative expansion that thoroughly solves different materials compound tense.
The invention has the beneficial effects as follows: 1, inner tube need only be wear-resisting, must not seal and pressure bearing, inner and outer pipes compound tense tip-clearance can not sealed.This makes inner and outer pipes be easy to assemble compound, after inner tube breakage, can extract on the spot replacing out.2, greatly improve in operational reliability and the working life in this wear-resisting composite pressure pipe road; 3, the function that outer tube is withstand voltage, inner tube is wear-resisting is separated, makes inner and outer pipes all can use most economical rational material and wall thickness, thereby greatly reduces costs.
Accompanying drawing explanation
Accompanying drawing is embodiment's longitudinal section tectonic maps, and this figure is applicable to flange and connects.
1. outer tubes in figure, 2. inner tube, 3. elastic material, 4. adpting flange, 5. sealed bolster plate, 6. only moves baffle ring, 7. plastic film or plastic sheet, 8. expansion compensation groove.
Embodiment
Inner and outer pipe is made respectively.Outer tube (1) adopts steel pipe, Glass Steel Tube or reinforced plastic pipe to serve as, in order to pressure-bearing.
Inner tube (2) adopts one section of homogeneous tube to make, and leaves longitudinal dilatation gap between inner tube one end and baffle ring.
Due to gapped between inner and outer pipe, after inner and outer pipes is made respectively, can assemble at an easy rate compound.
Elastic material in inner and outer pipes interlayer (3) adopts elaxtic seal or elasticity filtering material according to different situations, can make rear winding in inner tube (2), be wrapped in its outer wall.
For preventing that inner tube (2) is along the slippage of media flow direction, the adpting flange of outer tube (1) (4) diameter is suitably strengthened, sealed bolster plate (5) thickening, only moves baffle ring (6) to install.This device is applicable to flange and connects, and sees accompanying drawing.Its termination move baffle ring (6) can with sealed bolster plate (5) one or split production, also can with inner tube integral production.In clip connected or socket joint connection, only move baffle ring (6) and can directly insert connection set inside.
When preservative treatment is done in steel outer tube wall and end, can adopt plastic film or plastic sheet (7) integral coating mode to isolate anticorrosion.
For guaranteeing that inner tube has enough longitudinal dilatation spaces, only moving of moving device only, on baffle ring (6), have expansion compensation groove (8).
For ease of processing, install, can by one end of inner tube (2) with only move baffle ring (6) integral manufacturing.
Claims (6)
1. a wear-resisting composite pressure pipe road, the inner tube that the outer tube being served as by the steel pipe in order to pressure-bearing, Glass Steel Tube or reinforced plastic pipe and high-abrasive material are made is composited, it is characterized in that inner tube is one section of homogeneous tube, between inner and outer pipes and inner tube longitudinally leave clearance for expansion, end is provided with the only moving device that prevents inner tube straight skidding.
2. wear-resisting composite pressure pipe according to claim 1 road, is characterized in that filling out with elastic material in inner and outer pipes gap.
3. wear-resisting composite pressure pipe according to claim 1 road, is characterized in that steel outer tube wall and end do preservative treatment.
4. wear-resisting composite pressure pipe according to claim 3 road, the anti-corrosion mode that it is characterized in that steel outer tube wall and end is that plastic film or the isolation of plastic sheet integral coating are anticorrosion.
5. wear-resisting composite pressure pipe according to claim 1 road, is characterized in that end stops only moving of moving device and on baffle ring, have expansion compensation groove.
6. wear-resisting composite pressure pipe according to claim 1 road, is characterized in that one end of inner tube and only moves baffle ring integral manufacturing.
