Abstract
The utility model relates to a reinforcing device for tube ends of condensers and heat exchangers, which is composed of a thin wall short tube, a heat exchange tube and a tube plate, wherein, the outer tube diameter of the thin wall short tube is equal to the inner tube diameter of the heat exchange tube, the thin wall short tube is composed of a straight tube and a curling edge which are mutually connected, the straight tube is arranged in the heat exchange tube, the outer surface of the straight tube is in extension connection with the inner surface of the heat exchange tube, the curling edge is arranged on the outer side of the port of the heat exchange tube, and the inner surface of the curling edge is tightly pasted on the outer surface of the tube plate. Compared with the prior art, the using effect and the service life of the original heat exchange tube can be ensured, and simultaneously the utility model has the advantages of simple operation and convenient operation.
Description
Technical field:
The utility model relates to a kind of maintenance unit of large industrial enterprise heat exchange equipment, particularly a kind of condenser, heat exchanger pipe end bracing means.
Background technology:
In existing technology, condenser, heat exchanger pipe end bracing means are divided into two kinds: a kind of is the plastic liner method, be about to that plastic liner is installed in the impaired of heat exchanger by pressing or bonding method or the pipeline that corroded in, its shortcoming is the internal diameter that has seriously reduced former pipeline, limited the flow that liquid enters heat exchanger, and liquid forms eddy current when plastic liner enters female pipe flowing out, and caused new hot spot, simultaneously plastic liner clean difficulty, easily lax, conformability is poor; Another kind is: the plastic coating method, be about to the inner surface of pipeline that synthetic resin directly is coated in the impaired of heat exchanger or is corroded, it is very high to being coated with surface requirements that its shortcoming is a plastic coating, because inner surface of pipeline impaired or that corroded has rust staining, causes the result of use of plastic coating poor, the life-span is short.
Summary of the invention:
Technical problem to be solved in the utility model is: when using the plastic liner method, plastic liner has seriously reduced former internal diameter of the pipeline, limited the flow that liquid enters heat exchanger, and liquid forms eddy current when the outflow plastic liner enters female pipe, caused new hot spot, simultaneously plastic liner clean difficulty, easily lax, conformability is poor; When using the plastic coating method, plastic coating is very high to being coated with surface requirements, because inner surface of pipeline impaired or that corroded has rust staining, causes the result of use of plastic coating poor, the life-span is short.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to provide a kind of condenser, heat exchanger pipe end bracing means, described condenser, heat exchanger pipe end bracing means is by the thin-walled short tube, heat exchanger tube and tube sheet constitute, the outer tube diameter of described thin-walled short tube equates with the interior caliber of heat exchanger tube, the degrees of expansion of described thin-walled short tube is by its caliber decision, the material of described thin-walled short tube is better than the physical property and the chemical property of the material of described heat exchanger tube, described thin-walled short tube is made of straight tube and crimping, described straight tube and described crimping are coupled to each other, described straight tube is arranged in the heat exchanger tube, the inner surface of its outer surface and described heat exchanger tube rises and is connected together, the concrete mode that connects that rises can rise with pipe-expander and connect, described heat exchanger tube can not excessive expansion, described crimping is arranged on the port outside of heat exchanger tube, and the inner surface of described crimping is close on the outer surface of described tube sheet.
The utility model and prior art contrast, because used condenser, heat exchanger pipe end bracing means, can be in the result of use that guarantees former heat exchanger tube with in service life, and simple to operate, easy to use.
Description of drawings:
Fig. 1 is the utility model condenser, heat exchanger pipe end bracing means schematic diagram.
The specific embodiment:
As shown in Figure 1, the novel condenser of the utility model, heat exchanger pipe end bracing means is by thin-walled short tube 1, heat exchanger tube 2 and tube sheet 3 constitute, the outer tube diameter of described thin-walled short tube 1 equates with the interior caliber of heat exchanger tube 2, the degrees of expansion of described thin-walled short tube 1 is by its caliber decision, the material of described thin-walled short tube 1 is better than the physical property and the chemical property of the material of described heat exchanger tube 2, described thin-walled short tube 1 is made of straight tube 4 and crimping 5, described straight tube 4 is coupled to each other with described crimping 5, described straight tube 4 is arranged in the heat exchanger tube 2, the inner surface of its outer surface and described heat exchanger tube 2 rises and is connected together, the concrete mode that connects that rises can rise with pipe-expander and connect, described heat exchanger tube 2 can not excessive expansion, described crimping 5 is arranged on the port outside of heat exchanger tube 2, and the inner surface of described crimping 5 is close on the outer surface of described tube sheet 3.
Claims (2)
1, a kind of condenser, heat exchanger pipe end bracing means, constitute by thin-walled short tube, heat exchanger tube and tube sheet, it is characterized in that: described thin-walled short tube is made of straight tube and crimping, described straight tube and described crimping are coupled to each other, and described straight tube is arranged in the heat exchanger tube, and the inner surface of its outer surface and described heat exchanger tube rises and is connected together, described crimping is arranged on the port outside of heat exchanger tube, and the inner surface of described crimping is close on the outer surface of described tube sheet.
2, condenser according to claim 1, heat exchanger pipe end bracing means is characterized in that: the outer tube diameter of described thin-walled short tube equates with the interior caliber of described heat exchanger tube.
