Description
Technical field
The utility model belongs to conveyance conduit technical field, and in particular to lining tetrafluoro pipeline.
Background technology
Lining tetrafluoro pipeline has been widely used in the industries such as chemical industry, metallurgy, mine, the energy, pharmacy, traditional lining tetrafluoro
Pipeline configuration design is simple, is exactly steel polytetrafluoroethyl-ne alkenes compound pipeline complex pipeline, can strong alkali-acid resistance, but its high temperature resistant and pressure resistance
Performance is poor, and during pipeline is laid with use, is easy the solvent conveyed in inner wall of the pipe residual packing, is unable to fully defeated
Solution is sent, accordingly, it is desirable to provide a kind of realization of novel tetrafluoro lined pipeline possesses preferable high temperature resistant and pressure-resistant performance, and can be effective
Avoid the accumulation of inner wall of the pipe residual conveying solvent.
Utility model content
The utility model provides lining tetrafluoro pipeline regarding to the issue above, it is therefore intended that realizes that lining tetrafluoro pipeline possesses preferably
High temperature resistant and pressure-resistant performance, and can effectively avoid the accumulation of inner wall of the pipe residual conveying solvent.
The technical solution of the utility model:
Serve as a contrast tetrafluoro pipeline, it is characterised in that:Including steel pipe and tetrafluoro pipeline, it is arranged four fluorine tube road in the steel pipe, and
Steel pipe also wraps up be equipped with high-temperature insulation thermal insulation layer outside with the molten middle layer together of tetrafluoro pipeline intermediate heat, the steel pipe, and described four
The inner circle radius that fluorine pipeline passes through becomes larger, and tetrafluoro pipeline inner circle hatching is described horizontal by oblique angle
Steel pipe both ends mounting flange.
The high-temperature insulation thermal insulation layer is made of ceramic fibre material.
The hatching of the tetrafluoro pipeline inner circle is horizontal by 2 °~6 ° of oblique angle.
The flange side is equipped with the arrow in mark direction, and the arrow direction becomes larger with tetrafluoro pipeline inner circle radius
Direction it is consistent.
The beneficial effects of the utility model:
The structure design of the utility model is reasonable, and using effect protrudes, and is arranged four fluorine tube road in steel pipe, and in steel pipe and tetrafluoro
One of middle layer is heated among pipeline, also package is equipped with high-temperature insulation thermal insulation layer outside steel pipe so that lining tetrafluoro pipeline possess compared with
Good high temperature resistant and pressure-resistant performance, the inner circle radius that tetrafluoro pipeline passes through becomes larger, and can effectively avoid pipeline
Inner wall residual conveying solvent accumulation, flange side be equipped with mark direction arrow, determined when install convenient for worker pipeline and
Fluid traffic direction it is consistent.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
Wherein:1 steel pipe, 2 tetrafluoro pipelines, 3 middle layers, 4 high-temperature insulation thermal insulation layers, 5 flanges, 6 arrows.
Specific implementation mode
Tetrafluoro pipeline, including steel pipe 1 and tetrafluoro pipeline 2 are served as a contrast, is arranged four fluorine tube road 2 in steel pipe 1, and in steel pipe 1 and tetrafluoro
Heat one of middle layer 3 among pipeline 2, also package is equipped with high-temperature insulation thermal insulation layer 4 outside steel pipe 1, tetrafluoro pipeline 2 from one end to
The inner circle radius of the other end becomes larger, and 2 inner circle hatching of tetrafluoro pipeline is horizontal by oblique angle, 1 both ends mounting flange of steel pipe
5。
Middle layer 3 can be fused to steel, but it is fusible be connected to tetrafluoride material, after tetrafluoro pipeline 2 is compound, by adding to steel pipe
Temperature is formed when middle layer 3 is suitable with 2 fusible jointing temp of tetrafluoro pipeline by inner wall pressurization cooling and shaping.
High-temperature insulation thermal insulation layer 4 is made of ceramic fibre material, is made of wet therapy forming process, has resistance to height
The performances such as warm, resistant to chemical etching, heat shock resistance, low thermal conductivity, high electric insulation intensity and high elastic modulus, feature are no stone
Cotton, fiber are long, slag ball is few, unit weight is small, intensity is big, elasticity is good, convenient for constructing operations such as punching, windings;After middle layer welding,
High-temperature insulation thermal insulation layer 4 can be wound and be wrapped in outside steel pipe 1.
The hatching of 2 inner circle of tetrafluoro pipeline can fully ensure that transport horizontal by 2 °~6 ° of oblique angle, in this way setting
Solution will not accumulate in tetrafluoro pipeline 2.
5 side of flange is equipped with the arrow 6 in mark direction, and arrow 6 is directed toward the side become larger with 2 inner circle radius of tetrafluoro pipeline
To consistent, worker installs consistent with fluid traffic direction convenient for determination when connecting pipe.
Lining tetrafluoro pipeline provided by the utility model, reasonable in design, using effect protrudes, and tetrafluoro is arranged in steel pipe 1
Pipeline 2, and middle layer 3, steel pipe 1 also wrap up heat-insulated equipped with high-temperature insulation hot melt outside together among steel pipe 1 with tetrafluoro pipeline 2
Layer 4 so that lining tetrafluoro pipeline possesses preferable high temperature resistant and pressure-resistant performance, the inner circle that tetrafluoro pipeline 2 passes through half
Diameter becomes larger, and can effectively avoid the accumulation of the solvent of inner wall of the pipe residual conveying, 5 side of flange is equipped with the arrow in mark direction
6, determine that pipeline is consistent with fluid traffic direction when being installed convenient for worker.
