Abstract
Having can the multiple tube of filling interlayer, when increasing operational reliability during filling padded coaming in interlayer, increases the service life.Inner and outer pipes is carried out eccentric compound better effects if.
Description
Art
The present invention relates to a kind of abrasive media conveyance conduit.
Background technique
The basic skills solving abrasive media conveyance conduit wear resistance adopts the pipeline of unlike material to carry out inside and outside compound.Inner and outer pipes gapless compound can produce some problems that cannot overcome, and has gap compound to be a kind of well solution.But multiple tube interlayer gap is too small at present, only meets needed for inner and outer pipes assembling compound and relative expansion, and do not utilize interlayer filling at utmost to increase operational reliability, increase the service life.
Summary of the invention
For improving the operational reliability of multiple tube, increase the service life, the present invention adopts following scheme:
Strengthen the inner and outer pipes mezzanine space of multiple tube, become that have can the multiple tube of filling interlayer.It is characterized in that inner and outer pipes interlayer size exceedes assembling compound and the space needed for relative expansion.Can filling padded coaming in inner and outer pipes interlayer.For solving abrasive media to " eccentric wear " problem of tube wall side, inner and outer pipes is carried out eccentric compound, and its mezzanine space width is differed, and space, side is greater than opposite side.
The invention has the beneficial effects as follows: 1, due to the increasing of mezzanine space, can the more padded coaming of filling.Especially " eccentric wear " side mezzanine space is comparatively large, and effect can be better.When interior pipe is worn out, this buffer layer plays important " second defence line " effect.2, abrasive media oneself filling, self-protection in pipeline can be utilized.
Accompanying drawing explanation
Accompanying drawing is the cross section tectonic maps of embodiment.
1. outer tubes in figure, pipe 2., 3. eccentric hoop.
Embodiment
Interior pipe location is given with eccentric hoop.
Claims (4)
1. having can the multiple tube of filling interlayer, it is characterized in that inner and outer pipes interlayer size exceedes assembling compound and the space needed for relative expansion.
2. multiple tube according to claim 1, is characterized in that filling padded coaming in interlayer.
3. multiple tube according to claim 1, is characterized in that inner and outer pipes carries out eccentric compound, and its mezzanine space width is differed, and space, side is greater than opposite side.
4. multiple tube according to claim 1, is characterized in that with eccentric hoop to interior pipe location.
