Abstract
The present invention relates to a kind of direct-buried steam pipeline, specifically relate to a kind of direct-buried steam pipeline with interior rolling structure, it comprises: working pipe, outer pillar, thermal insulation layer and support group; Described support group is arranged between working pipe and outer pillar; thermal insulation layer is between working pipe and outer pillar; when 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 to be destroyed; keep the integrity of thermal insulation layer, decrease pipeline heat loss, the hull-skin temperature of external protective steel tube reduces; protect anticorrosive coat, extend pipeline working life.
Description
Technical field
The present invention relates to a kind of direct-buried steam pipeline, specifically relate 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 most of structure stand and working pipe are fixed as one 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, to 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, add the thermal loss of pipeline, reduce heat insulation effect, the hull-skin temperature of pipeline is increased, destroy the anticorrosive coat of external protective steel tube, decrease the working life of pipeline.
Summary of the invention
In view of prior art Problems existing, the object of the invention is to provide a kind of direct-buried steam pipeline with interior rolling structure, radial direction or axial displacement can be produced under the state of the medium High Temperature High Pressure of steam line conveying, 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 technical solution adopted in the present invention 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, are provided with gap between described thermal insulation layer and working pipe; 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, and be respectively rolling wheels and lower rolling wheels, 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 and working pipe and outer pillar are linear contact lay.
Gap is provided with between described flange plate and working pipe.
Described upper and lower two groups of scroll wheels comprise some scroll wheels respectively, and described scroll wheel is evenly crisscross arranged on ring flat-plate.
The invention has the advantages that:
1, this structural type is when 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 to be destroyed; keep the integrity of thermal insulation layer, decrease pipeline heat loss, the hull-skin temperature of external protective steel tube reduces; protect anticorrosive coat, extend pipeline working life.
2, the contact of support and working pipe and outer pillar realizes by scroll wheel, and be the rolling friction of linear contact lay, coefficient of rolling friction is less in existing friction factor, effectively decreases the loss of heat.
