Description

Technical Field

[0001] This utility model relates to the field of alloy pipe technology, and in particular to an environmentally friendly new material alloy pipe that can be used in high-speed locomotives. Background Technology

[0002] Alloy steel pipe is a type of seamless steel pipe with significantly higher performance than ordinary seamless steel pipe. Due to its higher chromium (Cr) content, alloy steel pipe possesses superior high-temperature resistance, low-temperature resistance, and corrosion resistance—properties unmatched by ordinary seamless steel pipe. Therefore, alloy steel pipe has wide applications in industries such as petroleum, aerospace, chemical, power, boiler, and military. For example, it plays a crucial role in high-pressure, high-temperature equipment and pipelines in power plants, nuclear power plants, high-pressure boilers, high-temperature superheaters, and reheaters.

[0003] The following problems exist: Alloy tubes are usually designed as single-layer tube structures. Although this structure has certain advantages in some aspects, its strength is relatively low, which makes alloy tubes prone to deformation during use. In addition, when multiple alloy tubes need to be connected to each other, the strength of the connection is often not ideal. This leads to bending, misalignment or detachment at the connection in practical applications, thus affecting the stability and reliability of the entire system. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] An environmentally friendly new material alloy tube that can be used in high-speed locomotives includes an inner tube. Multiple sets of outer rings are fixedly connected to the outer wall of the inner tube. An outer tube is fixedly connected to the outer wall of the outer ring. A first flange ring is fixedly connected to one end face of the inner tube and the outer tube. A second flange ring is fixedly connected to the other end face of the inner tube and the outer tube. An insert tube is fixedly connected to the inner wall of the first flange ring. A rubber sleeve is fixedly connected to one end of the outer wall of the insert tube. The outer wall of the rubber sleeve of one set of alloy tubes can be sleeved with one end of the inner wall of the inner tube of another set of alloy tubes.

[0007] As a further description of the above technical solution:

[0008] A rubber ring is fixedly connected to one end face of the second flange ring, and multiple sets of insert rings pass through the outer edge of the second flange ring. Each insert ring has a limit ring fixedly connected to the outer edge of one end face.

[0009] As a further description of the above technical solution:

[0010] The outer wall of each limiting ring is threaded with a cover, and a spring cylinder passes through the center of the top of each cover. A return spring is sleeved on the top of the inner wall of each spring cylinder.

[0011] As a further description of the above technical solution:

[0012] A spring rod is slidably connected to the bottom of the inner wall of the spring cylinder, and a rotating shaft is rotatably connected to the bottom of the spring rod. A pressure plate is fixedly connected to the bottom of the rotating shaft.

[0013] As a further description of the above technical solution:

[0014] Multiple sets of threaded rods are fixedly connected to the outer edge of one end face of the first flange ring, and each threaded rod has a threaded tube threaded to one end of its outer wall.

[0015] As a further description of the above technical solution:

[0016] The outer wall of the threaded rod penetrates the insert ring and extends into the limiting ring, and the outer wall of the threaded tube can be sleeved with the inner wall of the limiting ring.

[0017] As a further description of the above technical solution:

[0018] The pressure plate can press the threaded tube, and the length of the threaded tube is greater than the length of the limiting ring.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] (1) By setting an inner tube and an outer tube, a double-layer tube structure can be achieved, which not only improves the strength that the alloy tube can withstand, but also reduces the occurrence of alloy tube deformation. When the two alloy tubes are connected, the rubber sleeve is inserted into the inner tube first, which not only limits the connection of the two alloy tubes, but also improves the sealing of the connection part of the two alloy tubes, and further enhances the strength of the connection part of the two alloy tubes.

[0021] (2) After the threaded tube is installed on the outer wall of the threaded rod, the cover is fixed on the limiting ring. As the cover rotates, the pressure plate will slowly press the threaded tube to prevent it from falling off. When the two metal pipes are connected, the rubber ring on the second flange ring is in close contact with the surface of the first flange ring on the other metal pipe. This not only improves the sealing of the connection between the two metal pipes, but also the force of the rubber ring expansion acts on the two metal pipes, which helps to improve the stability of the connection between the two metal pipes.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0030] Reference Figure 1-3 This utility model provides an embodiment of an environmentally friendly new material alloy tube that can be used in high-speed locomotives. The tube includes an inner tube 1, with multiple sets of outer rings 2 fixedly connected to the outer wall of the inner tube 1. An outer tube 3 is fixedly connected to the outer wall of the outer rings 2. By setting the inner tube 1 and outer tube 3, a double-layer tube structure can be achieved, which not only improves the strength that the alloy tube can withstand but also reduces the occurrence of deformation. A first flange ring 4 is fixedly connected to one end face of the inner tube 1 and the outer tube 3, and a second flange ring 5 is fixedly connected to the other end face of the inner tube 1 and the outer tube 3. The size of the first flange ring 4 is the same as the size of the second flange ring 5. A rubber ring 6 is fixedly connected to one end face of the second flange ring 5. Multiple sets of insert rings 7 pass through the outer edge of the second flange ring 5, and a limit ring 8 is fixedly connected to the outer edge of one end face of each insert ring 7.

[0031] The outer wall of the limiting ring 8 is threaded with a cover 9. A spring cylinder 10 passes through the center of the top of the cover 9. A return spring 11 is sleeved on the top of the inner wall of the spring cylinder 10. A spring rod 12 is slidably connected to the bottom of the inner wall of the spring cylinder 10. The bottom end of the spring rod 12 extends into the interior of the spring cylinder 10. A rotating shaft 13 is rotatably connected to the bottom of the spring rod 12. A pressure plate 14 is fixedly connected to the bottom of the rotating shaft 13. An insertion tube 15 is fixedly connected to the inner wall of the first flange ring 4. A rubber sleeve 16 is fixedly connected to one end of the outer wall of the insertion tube 15.

[0032] Multiple sets of threaded rods 17 are fixedly connected to the outer edge of one end face of the first flange ring 4. Each threaded rod 17 has a threaded tube 18 threaded to one end of its outer wall. The outer wall of the rubber sleeve 16 can fit into the inner wall of the inner tube 1. When the two sets of metal tubes are connected, the rubber sleeve 16 is first inserted into the inner tube 1. This not only limits the connection between the two sets of metal tubes but also improves the sealing of the connection, further enhancing the strength of the connection. The outer wall of the threaded rod 17 penetrates the insertion ring 7 and extends into the limiting ring 8. The outer wall of the threaded tube 18 can fit into the inner wall of the inner tube 1. After the inner wall of the limiting ring 8 is fitted with the threaded tube 18 and the outer wall of the threaded rod 17 is installed, the cover 9 is fixed on the limiting ring 8. As the cover 9 rotates, the pressure plate 14 will slowly press the threaded tube 18 to prevent it from falling off. After the two combined metal tubes are connected, the rubber ring 6 on the second flange ring 5 is in close contact with the surface of the first flange ring 4 on the other combined metal tube. This not only improves the sealing of the connection between the two combined metal tubes, but also the expansion force of the rubber ring 6 acts on the two combined metal tubes, which helps to improve the stability of the connection between the two combined metal tubes.

It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
