Abstract
The utility model provides a heat preservation elbow with an expansion joint. The heat preservation elbow comprises a roasted elbow, a fiber reinforced protection layer sleeved on the outer side of the roasted elbow and a heat preservation layer positioned between the roasted elbow and the fiber reinforced protection layer, wherein a protruded wavy expansion joint pipe integrally connected with the roasted elbow is arranged on the middle part of the roasted elbow. The heat preservation elbow with the expansion joint has the beneficial effects that the heat preservation layer and the fiber reinforced protection layer which are positioned on the outer side of the roasted elbow can effectively guarantee the temperature of a fluid medium; furthermore, the expansion joint pipe is additionally arranged on the middle part of the roasted elbow, so that pipeline deformation caused by temperature change can be effectively prevented; the heat preservation elbow with the expansion joint is simple in structure and convenient to use, and the mechanical performance and the heat preservation quality of a product are guaranteed.
Description
Technical field
The utility model belongs to insulation pipe technical field, especially relates to a kind of heat-preserving bent pipe with expansion joint.
Background technique
At present, growing along with national economy, people's lives improve constantly, and central heat supply is deeply concerned, by country, is classified as key construction project.Heat-insulating pipe fitting is important component part in heat supply pipeline, and due to the increase of large size heat supply amplitude, heat supply pipeline bore increases gradually, and the production of heavy caliber heat-insulating pipe fitting becomes current a great problem.
Large-caliber pipe fittings can only adopt welding procedure manufacture at present, and the bend pipe being generated by welding is prone to weld defects, and current bend pipe heat insulation effect is bad, causes the waste of the energy.
Summary of the invention
The purpose of this utility model is to provide a kind of heat-preserving bent pipe with expansion joint of simple in structure, easy to use, good heat insulating.
The technical solution of the utility model is: a kind of heat-preserving bent pipe with expansion joint, comprise and simmer bend pipe processed, be set in the fiber of simmering bend pipe processed outside and strengthen protective coating and the thermal insulation layer between stewing bend pipe processed and fiber reinforcement protective coating, the middle part of described stewing bend pipe processed is provided with and the protruding corrugated-type expansion joint pipe of simmering bend pipe processed and being connected as a single entity.
Further, the both sides that are positioned at expansion pipe joint at stewing bend pipe processed are also provided with fastening clamp, and this fastening clamp is set in fiber and strengthens on the outer wall of protective coating.
Further, described thermal insulation layer is alumina silicate rock wool or asbestos.
Further, the bend angle of described stewing bend pipe processed is 1-180 °.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, thermal insulation layer and fiber by stewing bend pipe processed outside are strengthened protective coating, can effectively guarantee the temperature of flowing medium, and install expansion pipe joint additional in the middle part of simmering bend pipe processed, can effectively prevent the pipeline distortion causing because of temperature variation, not only simple in structure, easy to use, but also guaranteed the mechanical property of product and be incubated quality.

In figure:
1, simmer bend pipe 2 processed, fiber reinforcement protective coating 3, thermal insulation layer
4, expansion pipe joint 5, fastening clamp
Embodiment
As shown in Figure 1,
The technical solution of the utility model is: a kind of heat-preserving bent pipe with expansion joint, comprise and simmer bend pipe 1 processed, be set in the fiber of simmering bend pipe processed 1 outside and strengthen protective coating 2 and the thermal insulation layer 3 between stewing bend pipe 1 processed and fiber reinforcement protective coating 2, the middle part of described stewing bend pipe 1 processed is provided with and the protruding corrugated-type expansion joint pipe 4 of simmering bend pipe 1 processed and being connected as a single entity.
In the present embodiment, the both sides that are positioned at expansion pipe joint 4 at stewing bend pipe 1 processed are also provided with fastening clamp 5, and this fastening clamp 5 is set in fiber to be strengthened on the outer wall of protective coating 2, and described thermal insulation layer 3 is alumina silicate rock wool, and the bend angle of described stewing bend pipe 1 processed is 90 °.
The working principle of this example and advantage: thermal insulation layer 3 and fiber by stewing bend pipe processed 1 outside are strengthened protective coating 2, can effectively guarantee the temperature of flowing medium, and install expansion pipe joint 4 additional at stewing bend pipe processed 1 middle part, can effectively prevent the pipeline distortion causing because of temperature variation, not only simple in structure, easy to use, but also guaranteed the mechanical property of product and be incubated quality.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
