[0030] How to improve the stability of two-stage platinum in connection after stretching and compression, to realize the overall management of platinum channel expansion, improve reliability and efficiency.

[0031] As Figure 1 The utility model provides a kind of expansion buffer device of platinum channel based on this, including device ontology, device ontology can be set to two platinum pipes to be connected, to form platinum pipe connecting pipe section;Wherein:

[0032] Device ontology includes buffer part and connecting flange group, connecting flange group is set between two platinum pipes to be connected, and connecting flange group can connect two platinum pipes to be connected by flange;

[0033] Buffer part is set to at least one platinum pipe to be connected, and buffer part is between the first pipe section 11 and the second pipe section 12 of platinum pipe to be connected;

[0034] Buffer part is annular structure, and the annular edge of annular structure is formed with buffer surface, and buffer surface extends outward along the side of platinum pipe to be connected to form arc convex ring.

[0035] The expansion buffer device of platinum channel of the utility model realizes the stability of platinum channel expansion, reduces system fluctuation and energy loss caused by uneven expansion, to improve the operating efficiency and stability of entire platinum channel expansion.

[0036] As Figure 1 In the expansion buffer device of platinum channel of the utility model, arc convex ring includes first convex ring and at least one second convex ring, and second convex ring and first convex ring are connected by axial edge.In some embodiments, second convex ring is provided as two, and two second convex rings are arranged on the axial two sides of first convex ring.It can be seen from the drawing that, taking first expansion ring 3 as an example, arc convex ring is first expansion ring 3, and first expansion ring 3 includes middle expansion buffer ring 31 and two sides connecting buffer ring 32, which are integrally formed.By arc-shaped buffer structure, the stability of platinum channel in stretching and compression process is realized.

[0037] In some specific embodiments, the first expansion ring 3 and the second expansion ring 4 of the utility model can be formed by machining on the basis of the first platinum tube 1 and the second platinum tube 2, such as by machining deformation, so that the first platinum tube 1 and the second platinum tube 2 form a convex arc at the part, and then form the buffer part. Alternatively, the first expansion ring 3 and the second expansion ring 4 are separately machined and then welded and assembled with the first platinum tube 1 and the second platinum tube 2, and the material needs to be selected similar to that of the first platinum tube 1 and the second platinum tube 2. Obviously, by machining the first expansion ring 3 and the second expansion ring 4 on the first platinum tube 1 and the second platinum tube 2, although the machining convenience may not be optimal, the stress concentration and potential leakage points at the connection can be effectively reduced, and the overall structural strength and sealing performance can be improved.

[0038] In some embodiments, the maximum radial dimension of the expansion buffer ring 31 of the utility model is not less than the maximum radial dimension of the connection buffer ring 32. In machining, the higher convex expansion buffer ring 31 is machined at the middle position of the buffer part, so as to improve the performance of the buffer. In specific embodiments, the height of the convex expansion buffer ring 31 can be machined to 10mm-15mm.

[0039] In order to further optimize the performance of the buffer part, and considering the machining efficiency and the rationality of the actual working condition, in some embodiments, the utility model selects to control the width dimension of the first expansion ring 3 and the second expansion ring 4 along the platinum tube to be connected in the axial direction to 50mm-80mm. In actual working conditions, the first expansion ring 3 and the second expansion ring 4 generally select the same width dimension, and of course, the height of the convex expansion buffer ring 31, the first expansion ring 3 and the second expansion ring 4 can be adjusted according to actual needs to adapt to the expansion amount of the platinum tube under different working conditions, and the flexibility and adaptability of the device are increased. In this way, on the basis of effectively guaranteeing the machining efficiency and the actual operation demand, the buffering effect is maximized. Based on the above more detailed machining, through the design of the expansion buffer ring 31 and the two connection buffer rings 32, and the design of the first expansion ring 3 and the second expansion ring 4, not only the buffering effect is increased, but also the expansion management is more precise. Different sizes and shapes of the expansion buffer ring 31 and the connection buffer ring 32 can be classified and buffered according to the different expansion amounts, further improving the efficiency and accuracy of the platinum channel expansion management.

[0040] As Figure 2As shown, in some embodiments, the utility model platinum channel expansion buffer device, the connecting flange group includes first flange 5 and second flange 6, and first flange 5 and second flange 6 are connected through several connecting bolts. In actual operation, several connecting screw holes 8 can be machined on first flange 5 and second flange 6, and then corresponding size connecting bolts 7 are equipped, so that the flange connection of first platinum tube 1 and second platinum tube 2 is realized. The number of connecting screw holes 8 and matching connecting bolts 7 can be selected according to actual needs, for example, four to eight can be selected. The utility model is connected through the connecting screw hole 8 on the first flange 5 and the second flange 6, and the connecting screw hole 8 is fixed on the first flange 5 and the second flange 6 by welding, as the stress area of connecting bolt 7. The utility model makes the installation process more simple and convenient through the design of connecting flange group and connecting bolt, and is also convenient for later maintenance and replacement.

[0041] The utility model also provides a kind of platinum tube section, and the platinum channel expansion buffer device described above can be applied to any two sections of entire platinum system, including locally distributed structure, which can be designed in this way.

[0042] In summary, the first expansion ring 3 and the second expansion ring 4 are the main structural features of the mechanical force generated by the two ends of the platinum during the expansion process, and the local tensile deformation and compression deformation are better; considering the balanced release of expansion force on the two platinum, the symmetric deformation is achieved as much as possible. The specific size of the first expansion ring 3 and the second expansion ring 4 needs to be calculated according to the total length of the first platinum tube 1 and the second platinum tube 2, that is, the total length and material of the first platinum tube 1 and the second platinum tube 2 determine the final expansion amount of the platinum channel when the temperature rises from room temperature to process temperature. In practice, there is a big difference between the actual expansion amount and the theory, that is, the actual platinum expansion amount will be much smaller than the theoretical expansion amount due to the constraint of other materials outside the platinum. According to the current structure size, the final expansion amount of the first platinum tube 1 and the second platinum tube 2 is generally in the range of 60mm~90mm. Therefore, in actual working conditions, it can be flexibly adjusted and designed according to actual needs.

[0043] In addition, the first flange 5 and the second flange 6 of the utility model are platinum channel main body structures assembled with the first platinum tube 1 and the second platinum tube 2 respectively, which bear the role of introducing current into the platinum channel through the current introduction part, and the first flange 5 and the second flange 6 are connected before the expansion starts to ensure the overall structure is firm

[0044] The first expansion ring 3 and the second expansion ring 4 of the utility model adopt an arc surface design higher than the original platinum tube body, and the height and width of the arc surface of the first expansion ring 3 and the second expansion ring 4 determine the length that the original platinum tube body can release, while the width of the arc surface of the first expansion ring 3 and the second expansion ring 4 alone determines the length that the original platinum tube body can be compressed.

[0045] The utility model discloses a whole expansion management is realized through the adjustment of structure, cancels the traditional segmented butt joint calibration link, adopts the expansion buffer function of structure self, can effectively offset the extrusion displacement problem of traditional expansion, ensures the integrity and security of equipment whole, provides important technical support for the development of substrate glass to higher efficiency.

[0046] Finally, it needs to be explained that: the above is only the preferred embodiment of the utility model, and does not limit the utility model in any form; ordinary technical personnel in the industry can implement the utility model according to the description and the above; however, the equivalent changes, such as some changes, modifications and evolution, made by the technical personnel familiar with the profession within the scope of the technical scheme of the utility model, using the technical content disclosed above, are equivalent embodiments of the utility model; at the same time, any equivalent changes, modifications and evolution of the above embodiments according to the essence of the utility model still belong to the protection scope of the technical scheme of the utility model.
