Abstract
The utility model disclose an adjustable type heat exchanging pipe positioning device, which is provided with a positioning core, an adjusting nut and an anti-loosening screw. By means of the adjustable type heat exchanging pipe positioning device, the screwing-out length of the adjusting nut is adjusted to be equal to the designed extending length according to the design requirements, and the aim that the length of heat exchanging pipes extending out of pipe plates is fast adjusted to be uniform is achieved. The adjustable type heat exchanging pipe positioning device is convenient and fast, saves time and labor, and greatly improves manufacture efficiency and manufacture quality of a heat exchanger.
Description
Technical field
The utility model belongs to the equipment manufacture industry heat exchanger and makes special tooling.
Background technology
Heat exchanger is a kind of common apparatus that is widely used in industries such as chemical industry, medicine, metallurgy, light industry, and in numerous heat exchanger structures, most popular is shell-and-tube heat exchanger.When making shell-and-tube heat exchanger, it is very time-consuming that the adjustment heat exchanger tube stretches out length to the designing requirement of tube sheet, thereby it is necessary to research and develop a kind of adjustable heat exchanger tube locator.
Summary of the invention
The purpose of the utility model will provide a kind of adjustable heat exchanger tube locator exactly; Reach the rapid adjustment heat exchanger tube and stretch out length to the regulation requirement of tube sheet and guarantee that heat exchanger tube stretches out the unified purpose of length of tube sheet, thereby improve the make efficiency and the fabricating quality of heat exchanger.
The purpose of the utility model is achieved in that adjustable heat exchanger tube locator, has location core, adjusting nut, and there is external screw thread in core stage casing, said location, and said adjusting nut is connected with the location core through internal thread.
As the utility model further scheme, said location core point diameter is slightly less than the heat exchanger tube internal diameter, the internal diameter of said adjusting nut is slightly larger than the external diameter of heat exchanger tube.
As the utility model improvement project, in a side of adjusting nut backing-up screw is set.
Use the utility model, can screw out length through the adjustment adjusting nut and make it to equal to design extension elongation according to designing requirement; Reach the unified purpose of length that the rapid adjustment heat exchanger tube stretches out tube sheet; Convenient and swift, time saving and energy saving, improve heat exchanger make efficiency and fabricating quality greatly.
Description of drawingsFig. 1 is the overall structure sketch map of the utility model, and Fig. 2 is the structural representation of the utility model adjusting nut 2, is described further below in conjunction with accompanying drawing.
The specific embodimentFig. 1 shows the structure of adjustable heat exchanger tube locator, and Fig. 2 shows the structure of adjustment nut, has location core 1, adjusting nut 2, and there is external screw thread in core 1 stage casing, location, and adjusting nut 2 is connected with location core 1 through internal thread.Location core 1 point diameter is slightly less than the heat exchanger tube internal diameter, can insert smoothly in the heat exchanger tube; The internal diameter of adjusting nut 2 is slightly larger than the external diameter of heat exchanger tube, can be enclosed within heat exchange pipe external surface smoothly, and can adjust back-out length.Side at adjusting nut 2 is provided with backing-up screw 3, and backing-up screw 3 screws out length adjustment at adjusting nut 2 and well can tighten later, prevents that adjusting nut 2 is loosening, guarantees that the size of adjusting does not change.
The use of the utility model: according to Design Requirement Drawing; Screw out length through adjustment adjusting nut 2 and make it to equal to design extension elongation; Tighten backing-up screw 3, stretch out tubesheet strength when slightly being longer than designing requirement at heat exchanger tube, location core 1 front end is filled in heat exchanger tube; Use external force to rap or touch the utility model, its adjustment nut 2 front end faces are contacted with the tube sheet end face get final product.
