Abstract
The utility model relates to the field of pipeline arrangement, in particular to a compensation device for thermal expansion of a pipeline. The composite compensation device comprises a movable sleeve, a corrugated pipe and a fixed sleeve, wherein the movable sleeve, the corrugated pipe and the fixed sleeve are sleeved outside a heat exchange pipe, the movable sleeve is connected with the fixed sleeve through the corrugated pipe, the outer wall of the movable sleeve is fixedly welded on a bottom plate in a sealing way, and the bottom end of the fixed sleeve is fixedly welded on the outer wall of the heat exchange pipe in a sealing way. Since the corrugated pipe is arranged on the lower part of the heat exchange pipe and the bottom of the sleeve is welded on the heat exchange pipe, a retractable reservation part is provided for thermal expansion and contraction of the heat exchange pipe. Sealing between the heat exchange pipe and the bottom plate is dually guaranteed by the filler and the sleeves, the problems of a continuously increasing clearance between the heat exchange pipe and the bottom plate and increasingly serious gas leakage caused by frequent thermal expansion and contraction and friction can be solved, the clearance between the heat exchange pipe and the bottom plate can be eliminated completely, and gas leakage can be avoided.
Description
Technical field
The utility model relates to the piping layout field, relates in particular to a kind of pipeline expanded by heating compensation device.
Background technique
Air heat exchanger is to use comparatively many a kind of heat-exchange apparatus in the present industrial enterprise, this kind equipment can effectively pass through used contaminated high-temperature gas to flow at pipe interior, pass through tube wall, to the low temperature clean gas heat radiation of pipeline external, energy shifts and recycling thereby reach.Existing air heat exchanger sealing position, shell is tubular structure, holds up and has fixed some hot channels at base plate and be convenient to manage interior gas and carry out sufficient heat exchange on every side.During at ordinary times air heat exchanger work, high-temperature gas causes the elongation of pipeline heat expansion by pipe interior, and when not working, temperature reduces again so that the pipeline shrinkage in the pipeline, and for a long time repeatedly, causing between pipeline and the base plate has the slit, and the gas pressure of pipeline external is larger than pipe interior gas pressure, so the phenomenon that constantly causes pipeline external gas to leak to pipe interior by the slit so that the pipeline external gas reclaiming rate descends, has reduced heat recovery efficient always.
Summary of the invention
Technical problem to be solved in the utility model provides the compound compensation device of a kind of pipeline expanded by heating, by one section bellows has been installed in the bottom of heat-exchange tube, and sleeve bottom is welded in hot traffic control, has avoided the generation of Leakage Gas phenomenon.
The utility model is achieved in that the compound compensation device of a kind of pipeline expanded by heating, comprise moving casing, bellows and fixed sleeving, described moving casing, bellows and fixed sleeving all are sleeved on outside the heat-exchange tube, link to each other by bellows between moving casing and the fixed sleeving, the outer wall welded seal of moving casing is fixed on the base plate, and the bottom welded seal of fixed sleeving is fixed on the outer wall of heat-exchange tube.
Be provided with cavity between described moving casing and the heat-exchange tube, be filled with filler in the described cavity.
The outer wall of described moving casing is by welding, and sealing is fixed on the base plate.
The bottom of described fixed sleeving is by welding, and sealing is fixed on the outer wall of heat-exchange tube.
The compound compensation device of the utility model pipeline expanded by heating is by having installed one section bellows in the bottom of heat-exchange tube, and sleeve bottom welded in hot traffic control, so that heat-exchange tube has flexible pre-allowance when expanding with heat and contract with cold, sealing between heat-exchange tube and the base plate is by filler and sleeve pipe double shield, having solved the friction of frequently expanding with heat and contract with cold causes heat-exchange tube and base plate gap constantly to enlarge, cause the day by day serious problem of Leakage Gas, by constantly replenishing filler, thoroughly eliminate the gap between heat-exchange tube and the base plate, avoided the generation of Leakage Gas phenomenon.
Description of drawings
Fig. 1 is the compound compensation device structural representation of the utility model pipeline expanded by heating.
Among the figure: 1 heat-exchange tube, 2 moving casings, 3 fillers, 4 base plates, the sealing of 5 soldering points, 6 bellowss, 7 fixed sleevings.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiments only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model statement, these equivalent form of values fall within the application's appended claims limited range equally.
As shown in Figure 1, the compound compensation device of a kind of pipeline expanded by heating, comprise moving casing 2, bellows 6 and fixed sleeving 7, described moving casing 2, bellows 6 and fixed sleeving 7 all are sleeved on outside the heat-exchange tube 1, link to each other by bellows 6 between moving casing 2 and the fixed sleeving 7, the outer wall sealing of moving casing 2 is fixed on the base plate 4, the bottom end seal of fixed sleeving 7 is fixed on the outer wall of heat-exchange tube 1, in the present embodiment, easy to process in order to install, the sealing between described moving casing 2 and base plate 4 and fixed sleeving 7 and the heat-exchange tube 1 is fixing all to be to realize by continuous soldering point sealing 5; Bellows 6 is so that heat-exchange tube 1 has flexible pre-allowance when expanding with heat and contract with cold, and the bottom welded seal of fixed sleeving 7 is fixed on the outer wall of heat-exchange tube 1, so that the gas in outside gas and the heat-exchange tube 1 is in state of isolation.
In the utility model, in order to improve the sealing effect between moving casing 2 and the heat-exchange tube 1, be provided with cavity between described moving casing 2 and the heat-exchange tube 1, be filled with filler 3 in the described cavity, so both expanded with heat and contract with cold for hot traffic control and reserved extending amount, eliminated the slit between heat-exchange tube 1 and the base plate 4, so that at first can't penetrating filler 3, gas leaks, avoided the generation of Leakage Gas phenomenon, filler can also constantly replenish, safeguard very convenient so that this compound compensation device has reached the effect of " dual fail-safe ".
