[0002] High-temperature resistant titanium alloy tube assemblies are tubular structural components made of high-temperature resistant titanium alloy materials. They are widely used in aerospace, military equipment, high-end industries and other fields. Titanium alloys have excellent high-temperature resistance, high strength, low density and good corrosion resistance, which enables the tube assembly to maintain stable performance in high-temperature environments while reducing structural weight.

[0003] It can be used to manufacture key parts such as engine components and high-temperature fluid transport pipelines, providing reliable connections and support for equipment under harsh conditions such as high temperature, high pressure, and high speed, meeting the high-performance material requirements of modern high-end equipment, and is an indispensable high-performance material component in modern industry.

[0004] When high-temperature resistant titanium alloy pipes are extended using flange connections, the vibration generated during the flow and transportation of the medium can cause the bolts on the flange to loosen over time. This can easily lead to leakage at the extended connection of the high-temperature resistant titanium alloy pipe, making it difficult to ensure the safe and stable operation of the pipeline system. Therefore, an expandable high-temperature resistant titanium alloy pipe assembly is proposed to address the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an expandable high-temperature resistant titanium alloy pipe assembly, which has good buffering capacity and can significantly reduce the impact of vibration generated during the flow and transportation of the medium on the expansion pipe body. Therefore, it is not easy for leakage to occur at the expansion connection between the main pipe body and the expansion pipe body, thereby ensuring the safe and stable operation of the pipeline system and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An expandable high-temperature resistant titanium alloy tube assembly includes a main tube body, an extension tube body on one side of the main tube body, a sealing assembly at the end of the main tube body near the extension tube body, and a plurality of mounting slots arranged in a ring array within the inner cavity of the main tube body near the extension tube body. A buffer assembly is provided within each mounting slot, and the buffer assembly includes a buffer airbag. The buffer airbag has a hollow structure. A first support plate is fixedly connected to the inner cavity of the buffer airbag near the mounting slot, and a second support plate is fixedly connected to the inner cavity of the buffer airbag near the extension tube body. A return spring is provided between the first and second support plates. The end of the extension tube body extends into the main tube body, and the buffer airbag is fixedly connected within the mounting slot.

[0008] As a further optimization of this utility model, the sealing assembly includes a limiting retaining ring, the inner diameter of which is smaller than the inner diameter of the main body, and the inner ring of which has a sealing groove.

[0009] As a further optimization of this utility model, a sealing ring is interference-fitted into the sealing groove, and the inner diameter of the sealing ring is smaller than the outer diameter of the expansion tube.

[0010] As a further optimization of this utility model, the two ends of the buffer airbag are arc-shaped and fit the inner end face of the mounting groove and the outer wall of the expansion tube, and the first support plate and the second support plate are arc-shaped and fit the two ends of the inner cavity of the buffer airbag.

[0011] As a further optimization of this utility model, the buffer airbag is provided with a connecting hole, which is located on the side of the buffer airbag near the expansion tube.

[0012] As a further optimization of this utility model, the following features are provided: a connecting pipe is provided on the side of the connecting hole near the expansion tube body, one end of the connecting pipe is inserted into the connecting hole and fixedly connected to the connecting hole, and several connecting grooves are provided in a ring array on the limiting ring.

[0013] As a further optimization of this utility model, the number of the connecting grooves and the connecting holes are equal and their positions are corresponding.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, the extension pipe allows for the connection between two main pipes. The sealing component provides a good seal at the connection between the extension pipe and the main pipe, preventing leakage of the medium. The mounting groove provides a mounting base for the buffer component, which in turn provides good buffering for the portion of the extension pipe extending into the main pipe. This significantly reduces the impact of vibrations generated during medium flow on the extension pipe, thus minimizing leakage at the connection between the main pipe and the extension pipe, thereby ensuring the safe and stable operation of the pipeline system.

[0025] Please see Figure 1-6 This utility model provides a technical solution:

[0026] An expandable high-temperature resistant titanium alloy tube assembly includes a main body 1, an extension tube 2 on one side of the main body 1, a sealing assembly 3 at the end of the main body 1 near the extension tube 2, and a plurality of mounting grooves 4 arranged in a ring array in the inner cavity of the main body 1 near the extension tube 2. A buffer assembly 5 is provided in the mounting groove 4, and the buffer assembly 5 includes a buffer airbag 51. The buffer airbag 51 is hollow. A first support plate 52 is fixedly connected to the end of the inner cavity of the buffer airbag 51 near the mounting groove 4, and a second support plate 53 is fixedly connected to the end of the inner cavity of the buffer airbag 51 near the extension tube 2. A return spring 54 is provided between the first support plate 52 and the second support plate 53. The end of the extension tube 2 extends into the main body 1, and the buffer airbag 51 is fixedly connected in the mounting groove 4.

[0027] As a further implementation of this solution, the sealing assembly 3 includes a limiting retaining ring 31. The inner diameter of the limiting retaining ring 31 is smaller than the inner diameter of the main pipe 1. The inner ring of the limiting retaining ring 31 has a sealing groove 32. A sealing ring 33 is interference-fitted into the sealing groove 32. The inner diameter of the sealing ring 33 is smaller than the outer diameter of the expansion pipe 2. The sealing assembly 3 can provide good sealing capability at the connection between the expansion pipe 2 and the main pipe 1, preventing the medium from leaking from the connection between the expansion pipe 2 and the main pipe 1.

[0028] As a further implementation of this solution, the two ends of the buffer airbag 51 are arc-shaped to fit the inner end face of the mounting groove 4 and the outer wall of the expansion tube 2. The first support plate 52 and the second support plate 53 are arc-shaped to fit the two ends of the inner cavity of the buffer airbag 51. The arc-shaped design of the buffer airbag 51 can be better installed in the mounting groove 4 and can better fit the outer wall of the expansion tube 2 to ensure the effectiveness of the buffer airbag 51.

[0029] As a further implementation of this solution, the buffer airbag 51 is provided with a connecting hole 511, which is located on the side of the buffer airbag 51 near the expansion tube 2. A connecting tube 512 is provided on the side of the connecting hole 511 near the expansion tube 2. One end of the connecting tube 512 is inserted into the connecting hole 511 and fixedly connected to the connecting hole 511. A number of connecting grooves 513 are arranged in a ring array on the limiting ring 31. The number of connecting grooves 513 and the connecting holes 511 are equal and their positions are corresponding. The end of the connecting tube 512 away from the connecting hole 511 passes through the limiting ring 31 through the connecting groove 513 and extends to the outside. The buffer airbag 51 can communicate with the outside through the connecting hole 511, the connecting tube 512 and the connecting groove 513. By communicating the buffer airbag 51 with the outside, it can help maintain the stability of the internal pressure of the buffer airbag 51. When the expansion tube 2 vibrates due to the flow of the medium or changes in external pressure, the buffer airbag 51 can release or absorb additional gas to maintain the balance of internal pressure.

[0030] Workflow: The expansion tube 2 can extend and connect the two main tubes 1, allowing them to communicate. The limiting ring 31 in the sealing assembly 3 can limit the expansion tube 2, preventing it from detaching from the main tube 1 under special circumstances. The sealing groove 32 can interference fit the sealing ring 33, which provides a good seal at the connection between the expansion tube 2 and the main tube 1, preventing leakage of the medium. The outer diameter of the sealing ring 33 will undergo elastic deformation due to the compression of the outer wall of the expansion tube 2, thereby filling the gap between the outer wall of the expansion tube 2 and the sealing ring 33 to achieve a good seal. The mounting groove 4 provides a mounting base for the buffer assembly 5, which provides good buffering for the portion of the expansion tube 2 extending into the main tube 1. When the medium passes through the expansion tube 2... When vibration occurs, the buffer airbag 51 will buffer the vibration. The first support plate 52 and the second support plate 53 can be fixedly connected to the return spring 54. The return spring 54 can drive the second support plate 53 to expand towards the expansion tube 2 through its own rebound force. Thus, the second support plate 53 drives the end of the buffer airbag 51 near the expansion tube 2 to expand, so that the end of the buffer airbag 51 near the expansion tube 2 fits more tightly with the outer wall of the expansion tube 2 to achieve a better buffering effect. The buffer airbag 51 can be connected to the outside through the connecting hole 511, the connecting pipe 512 and the connecting groove 513. By connecting the buffer airbag 51 to the outside, it can help maintain the stability of the internal pressure of the buffer airbag 51. When the expansion tube 2 vibrates due to the flow of the medium or changes in external pressure, the buffer airbag 51 can release or absorb additional gas to maintain the balance of internal pressure.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
