Abstract

The utility model relates to a directly-buried steam pipeline, and in particular to a directly-buried steam pipeline with an internal rolling structure. The directly-buried steam pipeline with the internal rolling structure comprises a working pipe, an outer protection pipe, a heat insulation layer and a support group, wherein the support group is arranged between the working pipe and the outer protection pipe; the heat insulation layer is located between the working pipe and the outer protection pipe; during the running of the pipeline, the internal rolling support structure, the heat insulation layer and the outer protection pipe integrally disclose, thus ensuring the relative movement between the working pipe and the heat insulation layer; the heat insulation layer is protected by an inner air layer from damages, and the integrity of the heat insulation layer is kept, thus reducing the heat loss of the pipeline; the temperature of the outer surface of the outer protection steel pipe is lowered, thus protecting an anticorrosive layer and prolonging the service life of the pipeline.

Description

A kind of direct-buried steam pipeline with interior rolling structure
Technical field
The utility model relates to a kind of direct-buried steam pipeline, specifically relates to a kind of direct-buried steam pipeline with interior rolling structure.
Background technique
At present, steam line inner supporting structure is various informative, but that most of structure stand and working pipe are fixed as one is motionless, and working pipe is expanded with heat and contract with cold, and support is telescopic moving together with working pipe.And thermal insulation layer is directly wrapped in working pipe, be integrated with working pipe, it expands with heat and contract with cold when working pipe, make that heat insulation layer structure is imperfect, the disconnection of thermal insulating material or gathering, the thermal loss that has increased pipeline, has reduced heat insulation effect, and the hull-skin temperature of pipeline is increased, destroy the anticorrosive coat of external protective steel tube, reduced the working life of pipeline.
Summary of the invention
In view of the problem of prior art existence, the purpose of this utility model is that a kind of direct-buried steam pipeline with interior rolling structure will be provided, under the state of the medium High Temperature High Pressure that steam line is carried, can produce radially or axial displacement, the direct-buried steam pipeline that this kind has an interior rolling structure can be good at ensureing complete, the compound action that reduces heat waste of thermal insulation layer, guarantees the safe operation of steam pipe line.
To achieve these goals, the technological scheme that the utility model adopts is the direct-buried steam pipeline with interior rolling structure, and it comprises: working pipe, outer pillar, thermal insulation layer and support group; Described support group is arranged between working pipe and outer pillar, and thermal insulation layer, between working pipe and outer pillar, is characterized in that: described support group, thermal insulation layer and outer pillar are fixed as an entirety, between described thermal insulation layer and working pipe, are provided with gap; Described support group is configured to by some, and described support comprises: flange plate, gusset plate, scroll wheel, ring flat-plate and fixed plate; Flange plate is set in working pipe, and described flange plate is connected with gusset plate; Gusset plate is connected with ring flat-plate, and ring flat-plate is provided with upper and lower two groups of scroll wheels, is respectively rolling wheels and lower rolling wheels, and described ring flat-plate is connected with fixed plate, and fixed plate is connected with outer pillar; Described upper rolling wheels contact with outer pillar, and described lower rolling wheels contact with working pipe.
Described support is that line contacts with working pipe and outer pillar.
Between described flange plate and working pipe, be provided with gap.
Described upper and lower two groups of scroll wheels comprise respectively some scroll wheels, and described scroll wheel is evenly crisscross arranged on ring flat-plate.
The utility model has the advantage of:
1, this structural type is in the time of conduit running; interior rolling support structure, thermal insulation layer and outer pillar global displacement; ensure that working pipe and thermal insulation layer are relative movement; interior air layer will protect it can be not destroyed; the integrity that keeps thermal insulation layer, has reduced pipeline heat loss, and the hull-skin temperature of external protective steel tube reduces; protect anticorrosive coat, extended pipeline working life.
2, support is realized with contacting by scroll wheel of working pipe and outer pillar, is the rolling friction of line contact, and coefficient of rolling friction is less in existing friction factor, has effectively reduced the loss of heat.
