Abstract
The utility model belongs to the compensation technology field of an expansion joint of a bellows of a pipeline system, and brings forward an expansion joint with a jacket heat tracing structure. The expansion joint comprises inner tubes (2) and a bellows (9). Two ends of the bellows (9) are connected with the corresponding two inner tubes (2), respectively. A heating tracing tube (3), mounted to correspond to each inner tube (2), sleeves each corresponding inner tube (2). A bellows outer tube (6), arranged to correspond to the bellows (9), sleeves the bellows (9) and is positioned in the center of the heating tracing tubes (3). A heating chamber is formed between the bellows (9) and the inner tubes (2) and also between the bellows outer tube (6) and the bellows (9). A heat tracing medium, with no need of a heat resistance layer, can be directly contacted with the inner tubes for heat exchange, and under a condition of certain heat exchange, a heat transfer temperature difference is reduced, and the heat exchange efficiency and the stability of the expansion joint are improved.
Description
Technical field
The utility model belongs to the compensation technique field of pipe-line system bellows expansion joint, is specifically related to a kind of expansion joint with jacket hot tracing structure.
Background technique
Maintaining at present common employing of pipeline internal medium temperature lays heat-insulating structure and carries out two kinds of methods of pipeline tracing design; Wherein, heat-insulating structure is generally comprised of thermal-protective coating, vapor barrier, thermal insulation layer etc., the thermal insulation property of thermal-protective coating can be along with the prolongation of time variation gradually, and thermal insulation layer lay the usability that can affect pipeline adjacent bonds member, increased the stress level of expansion joint structure part.Comparatively speaking, comparatively stable by the pipeline medium temperature of companion's thermal design; Companion's hot mode is divided into interior TRACER companion heat, outer TRACER companion's heat and several modes of jacket hot tracing, by pipeline and pipeline indirect heat exchange;
Wherein, interior TRACER companion heat construction engineering work load is large, can not be for delivery of the medium of corrosivity or thermal sensitivity, and outer TRACER companion heat, the thermal efficiency is low.
Model utility content
For solving the problems of the technologies described above, the purpose of this utility model is to propose a kind of expansion joint with jacket hot tracing structure.
The utility model adopts following technological scheme for completing above-mentioned purpose:
An expansion joint with jacket hot tracing structure, described expansion joint includes inner tube and bellows; The two ends of described bellows are connected with corresponding inner tube respectively; Corresponding two described inner tubes are provided with TRACER, and the TRACER described in two is nested with the outside in inner tube; Corresponding described bellows arranges bellows outer tube; Described bellows outer tube is nested with the outside at bellows, and described bellows outer tube is connected between two described TRACER and with TRACER; Between described TRACER and inner tube, between bellows outer tube and bellows, form the heating chamber that bellows is heated, and corresponding described heating chamber arranges heat transferring medium and takes over.
Outer installment at described bellows outer tube has interior safety cover and outer protective cover; Described interior safety cover, outer protective cover are fixed in TRACER by corresponding ring flat-plate respectively.
Described heating chamber is provided with heat transferring medium outlet, and the outlet of described heat transferring medium is taken over and is arranged symmetrically with up and down with heat transferring medium.
A kind of expansion joint with jacket hot tracing structure the utility model proposes, in the outside of inner tube TRACER, arranged outside bellows outer tube at bellows, between described bellows and inner tube, between bellows outer tube and bellows, form the heating chamber that bellows is heated, make to accompany thermal medium and inner tube, bellows directly contact carries out heat exchange, reduced one deck thermal resistance, in the situation that heat exchange amount is certain, can reduce heat transfer temperature difference, guaranteed the temperature levels of medium in process pipe, maintain the temperature of pipeline internal medium during production operation and stopping transportation, avoid producing thermal loss because jump in temperature makes pipeline internal medium, solidify the generation with the phenomenon of crystallization, improved the stability of heat exchange efficiency and expansion joint, reduce and finish component stress, in addition, by the distortion of bellows outer tube and bellows, can absorb the thermal walking of piping temperature variation generation, thereby improve the safety and reliability of expansion joint, meanwhile, accompany hot outer tube to realize thermal compensation according to temperature variation.

Embodiment
With specific embodiment, the utility model is illustrated by reference to the accompanying drawings:
As shown in Figure 1, a kind of expansion joint with jacket hot tracing structure, described expansion joint includes inner tube 2 and bellows 9; Described inner tube is two; The two ends of described bellows 9 are connected with corresponding inner tube 2 by retaining ring II 11 respectively; Corresponding described inner tube 2 is provided with TRACER 3, and the TRACER described in two 3 is nested with in the outside of inner tube 2, and described TRACER by ring flat-plate 5 welding on inner pipe; Corresponding described bellows 9 arranges bellows outer tube 6; Described bellows outer tube 6 is nested with in the outside of bellows 9, and described bellows outer tube 6 is connected between two described TRACER 3 and with TRACER 3; Between described TRACER 3 and inner tube 2, between bellows outer tube 6 and bellows 9, form the heating chamber that bellows is heated, and corresponding described heating chamber arranges heat transferring medium and takes over 4; Described heating chamber is provided with heat transferring medium outlet, and the outlet of described heat transferring medium is taken over and is arranged symmetrically with up and down with heat transferring medium.
Outer installment at described bellows outer tube 6 has interior safety cover 7 and outer protective cover 8; Described interior safety cover, outer protective cover are fixed in TRACER 3 by corresponding ring flat-plate respectively.
When the temperature of whole pipeline changes, TRACER 3 is carried out bit shift compensation with bellows 9, can realize like this companion's heat, also can be because of the normal operation displacement of structural member and TRACER interference effect bellows.
