Description
Technical field
The utility model relates to the heat exchange equipment field of high temperature difference, is specially a kind of floating type tubular sheet heat exchanger.
Background technology
Tubular sheet heat exchanger, owing to being subject to the impact of medium temperature change, work under making cylindrical shell and heat exchanger tube be in different state of temperatures separately, and the effect of expanding with heat and contract with cold, make cylindrical shell and tube sheet, exchanger tubes and tubesheets produce the distortion of thermal stress, directly have influence on the sealing between the tube sheet of equipment and flange, exchanger tubes and tubesheets; The operating mode that particularly temperature difference is large, the distortion that temperature causes is larger, the direct service life affecting equipment.Common movable tube sheets heat exchanger solves the problem of some thermal stress deformations to a certain extent, still there is complex structure, and leakage point is not easily observed, the drawback of repairing and dismounting difficulty.
Therefore, providing a kind of structure simple, good seal performance, and change quick-wear part new type heat exchanger simply and easily, has been a good problem to study.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provides a kind of solution heat exchanger at high operating temperatures, the swollen shrinkage of heat caused due to temperature and the stress shape formed are on the impact of equipment sealing property, structure is being heated or is being made the sealing property of equipment not by the impact of temperature in cooling procedure, hermetically-sealed construction also can supervise the sealing situation of equipment at any time, changes consumable accessory floating type tubular sheet heat exchanger simply and easily.
The purpose of this utility model is achieved in that
A kind of floating type tubular sheet heat exchanger, comprise cylindrical shell 1, be arranged on the heat exchanger tube 10 in cylindrical shell 1, and be arranged on first tube sheet 7 and second tube sheet 11 at cylindrical shell 1 two ends, and first bobbin carriage 6 and second bobbin carriage 12 that arrange corresponding to the first tube sheet 7 and the second tube sheet 11, it is characterized in that: the first described bobbin carriage 6 by flange 3, hold-down ring 4, metallic packing ring 5, snap ring 8 and rubber seal ring 9 and the first bobbin carriage 6 compression fit, forms integrative-structure with cylindrical shell 1 by holding screw 2;
Described cylindrical shell 1 and be sliding connection structure between the first tube sheet 7 and hold-down ring 4, middlely seals by arranging rubber seal ring 9; The naked leakage of cylindrical of the first described tube sheet 7 outside.
positive beneficial effect:1. the utility model adopts the sealing of slip compression type, solves the equipment leakage problem because thermal deformation causes; 2. the utility model adopts sliding structure, eliminates the stress deformation of equipment, solves cooling tube and panel weld problem of Cracking in use; 3. the utility model adopts tube sheet is external, and in equipment operation process, the sealing problem caused due to tube sheet is convenient to observe, can Timeliness coverage.And easy to maintenance, consumable accessory is changed simple; Compact conformation, with usefulness equipment compare lightweight, volume is little.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is partial structurtes enlarged diagram of the present utility model;
In figure be: cylindrical shell 1, holding screw 2, flange 3, hold-down ring 4, metallic packing ring 5, first bobbin carriage 6, first tube sheet 7, snap ring 8, rubber seal ring 9, heat exchanger tube 10, first tube sheet 11, second tube sheet 12.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, a kind of floating type tubular sheet heat exchanger, comprise cylindrical shell 1, be arranged on the heat exchanger tube 10 in cylindrical shell 1, and be arranged on first tube sheet 7 and second tube sheet 11 at cylindrical shell 1 two ends, and first bobbin carriage 6 and second bobbin carriage 12 that arrange corresponding to the first tube sheet 7 and the second tube sheet 11, the first described bobbin carriage 6 passes through holding screw 2 by flange 3, hold-down ring 4, metallic packing ring 5, snap ring 8 and rubber seal ring 9 and the first bobbin carriage 6 compression fit, integrative-structure is formed with cylindrical shell 1, during variations in temperature, cylindrical shell and tube sheet can free-extensions, the distortion that elimination thermal stress causes and leakage, to adapt to high temperature difference, the needs of high pressure heat exchanger, eliminate the distortion dependence rubber seal ring sealing that thermal stress causes.。
Described cylindrical shell 1 and be sliding connection structure between the first tube sheet 7 and hold-down ring 4, middlely seals by arranging rubber seal ring 9; The naked leakage of cylindrical of the first described tube sheet 7 outside, is convenient to the leakage situation of equipment of supervising in time, and is changed seal in time.
The described pretension effect by holding screw bolt, makes the thrust of metallic packing ring and rubber seal ring, is finally provided by the shearing force being applied to snap ring.
The utility model utilizes object temperature influence to produce the principle of stress deformation dexterously, prearrangement of deformation amount space between equipment component, by holding screw, flange, hold-down ring, metal loop seals, snap ring are connected compression with the first bobbin carriage, thus make rubber seal ring play sealing function, simultaneously can free-extension between cylindrical shell and flange, heat exchanger tube by medium temperature variable effect and expand, shrink time, the first tube sheet can be free to slide, and does not affect the sealing property of equipment.
By the pretension effect of holding screw in the utility model, the thrust of parts metallic packing ring and rubber seal ring is finally provided by the shearing force being applied to snap ring by hold-down ring, makes the effect of being stressed of metallic packing ring and rubber seal ring and play the effect of sealing.
Tube sheet is external, and the sealing problem that tube sheet causes is very directly perceived, can Timeliness coverage.And easy to maintenance, consumable accessory is changed simple; Compact conformation, with usefulness equipment compare lightweight, volume is little.
Sealing property through testing equipment reaches designing requirement, produces a desired effect in equipment is on active service.
The above, it is only preferred embodiments of the present utility model, not any pro forma restriction is done to the utility model, every any simple modification above embodiment done according to technical spirit of the present utility model, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
