Abstract
The utility model relates to a heating pipe, in particular to a heating pipe mechanism capable of preventing a stand column from thermal expansion displacement. The heating pipe mechanism mainly solves the technical problems that in the prior art, when thermal transmission is conducted through a pipe mechanism, longitudinal thrust force is produced due to thermal expansion of a heating pipe, and destructive consequences are caused to the structure of a support. The heating pipe mechanism comprises the stand column (1) and is characterized in that the support (2) is arranged on the stand column (1), a steel plate (3) is arranged on the support, a plastic board (4) is arranged on the upper surface of the steel plate, a pipe support (5) is arranged on the plastic board, a steel pipe (6) is fixed to the pipe support, and the steel pipe is wrapped by a thermal insulating layer (7).
Description
Technical field
The utility model relates to a kind of heat supply pipeline, especially relates to a kind of heat supply pipeline mechanism of anti-column thermal expansion displacement.
Background technique
Along with socioeconomic development, the application of heat and power system in each city is more and more extensive, and coverage rate is also increasing.As everyone knows, the heat supply pipeline of heat and power system needs insulation conventionally, otherwise its heat can, along the surface volatilization of body, reduce heating effect.Chinese patent discloses a kind of thermoelectricity plant steam line (notice of authorization number: CN 2842150Y), it comprises thermal insulation steam pipeline, underground construction section at thermal insulation steam pipeline is provided with thermal insulation waterproof jacket, thermal insulation waterproof jacket is processed by pulverized fuel ash, be socketed in the outside of thermal insulation steam pipeline, in the ground of thermal insulation steam pipeline, construction section is coated with uvioresistant waterproof roll, and be fixed on rock or body of wall by U-shaped dunnage and supporting leg, the elbow part of thermal insulation steam pipeline is by interior conduit elbow, thermal insulation layer and outer combination steel bushing elbow form, thermal insulation layer is arranged between outer combination steel bushing elbow and interior conduit elbow, outer combination steel bushing elbow combines steel bushing elbow outward by two halves and forms ground split structure, outer combination steel bushing elbow fits together by seam welding is installed, thermal insulation layer is similarly split structure, cement in respectively on the inwall that two halves combine steel bushing elbow outward, in the middle of thermal insulation layer, be provided with the groove matching with interior conduit elbow shape, the condensate drain being arranged on thermal insulation steam pipeline comprises internal steam pipe road, ponding chamber, interior steel bushing, inner thermal insulating layer, waste pipe, waste pipe thermal insulation layer and waste pipe steel sleeve, internal steam pipe road is arranged in interior steel bushing, between internal steam pipe road and interior steel bushing, be provided with inner thermal insulating layer, waste pipe is connected with the ponding chamber that is arranged on bottom, internal steam pipe road, waste pipe is outside equipped with waste pipe steel sleeve, between waste pipe and waste pipe steel sleeve, be provided with waste pipe thermal insulation layer, interior steel bushing is outside equipped with outer steel sleeve, waste pipe passes from outer steel sleeve side after being 90 degree arc bendings along interior steel bushing periphery, between interior steel bushing and outer steel sleeve, be provided with external thermal insulation.But this pipeline mechanism is when carrying out heat transmission, and heat supply pipeline can be received thermal expansion and produce longitudinal thrust, thereby cause the destructive consequence of supporting structure.
Model utility content
The utility model is to provide a kind of heat supply pipeline mechanism of anti-column thermal expansion displacement, it is mainly to solve the existing pipeline mechanism of prior art when carrying out heat transmission, heat supply pipeline can receive thermal expansion and produce longitudinal thrust, thereby causes the technical problem of the destructive consequence etc. of supporting structure.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The heat supply pipeline mechanism of anti-column thermal expansion displacement of the present utility model, comprises column, on described column, is fixed with support, support is provided with steel plate, and upper surface of steel plate is provided with plastic board, and plastic board is provided with conduit saddle, on conduit saddle, be fixed with steel pipe, steel pipe outer wrap has thermal insulation layer.Support of pipelines is fixed on steel structure factory building column, apart from 5 meters of ground levels, and 70 meters of length.Below pipeline, be welded and fixed with conduit saddle, fixed support and column are welded and fixed, and all the other are sliding support, use plastic material transition between conduit saddle and support, when the displacement of pipeline expanded by heating, reduce frictional force, the vibration occurring while reducing piping displacement as far as possible and noise.Thermal expansion of pipeline coefficient 3 ‰, approximately 210 millimeters of overall expansion distances.
As preferably, between described column and support, be fixed with channel-section steel.On 14 factory building columns, increase length and be the 25# channel-section steel of 70 meters, make factory building column become as a whole, then welding support thereon, make it enough intensity and bear the thrust that the thermal expansion of pipeline causes.
As preferably, the outer surface of described thermal insulation layer is provided with malthoid, glass, aluminium protective layer, can comprise that thermal insulation layer can not suffer erosion.
Therefore, the utility model utilizes sliding support, overcomes the destructive result that large-scale pipeline causes because of thermal expansion, and vibration and noise phenomenon do not appear in conduit running balance substantially, respond well, simple and reasonable for structure.
