Description

Technical Field

[0001] This invention relates to the field of steam transportation technology, and more particularly to a steam transportation vibration damping pipeline. Background Technology

[0002] Steam pipelines are insulated composite pipelines used to transport high-temperature steam. They are widely used in urban heating, thermal power generation, and other fields.

[0003] Chinese utility model patent with publication number CN207848747U discloses a rock wool insulated steam conveying pipe, including a base plate, a base, and a steam pipe. Ribs are provided on both sides of the upper end of the base plate. A fixing plate is provided on the side of the base away from the ribs. A base is provided on the side of the fixing plate away from the ribs. Connecting blocks are provided on both sides of the upper end of the side wall of the base. A connecting plate is provided on the upper end of the connecting blocks. Bolts, nuts, and washers are provided on the connecting plates. A pipe groove is provided in the middle of the upper end of the base. A steam pipe is installed in the pipe groove. The steam pipe is provided with an inner wall, an outer wall, a rock wool layer, a reflective fiber, a tin foil layer, and a heat insulation layer. A fixing ring is provided at the upper end of the steam pipe near the connecting plate. The fixing ring is provided with a ring edge and a screw hole. When using the aforementioned rock wool insulated steam transmission pipe, first place the steam pipe on the pipe groove, then fix the fixing ring and connecting plate with bolts and nuts to secure the steam pipe. After fixing, steam can be introduced into the steam pipe. When the steam flows in the steam pipe, it will transfer heat through the inner wall to the rock wool layer. The rock wool layer can prevent the heat in the steam from being lost. After passing through the rock wool layer, the heat is further preserved by the reflective fiber. After passing through the reflective fiber, the heat finally passes through the insulation layer. Under the action of the insulation layer, the heat can be well preserved in the steam pipe to ensure the temperature of the steam during the transmission process.

[0004] The rock wool insulated steam conveying pipe disclosed in the above-mentioned utility model patent uses bolts and nuts to fix the fixing ring and the connecting plate to fix the steam pipe. Due to the high pressure inside the steam pipe, the steam pipe will vibrate during the process of transporting high temperature steam inside the steam pipe. During the vibration of the steam pipe, it will collide with the connecting ring and other parts, causing the steam pipe to deform or the connecting ring and other parts to be damaged, which will affect the normal transportation of steam and create safety hazards. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a steam conveying vibration-damping pipe, which solves the problem of steam pipe deformation or component damage caused by vibration in existing technologies.

[0006] According to an embodiment of the present invention, a steam conveying vibration damping pipe includes a base and a pipe body disposed on the base. The base is provided with a sliding groove and a movable clamping assembly is provided in the sliding groove. The moving direction of the clamping assembly is consistent with the axial direction of the pipe body. A plurality of buffer springs are also provided in the sliding groove, and the buffer springs respectively abut against the opposite sides of the clamping assembly. The extension and contraction directions of the buffer springs are consistent with the axial direction of the pipe body. The clamping assembly includes a plurality of clamping blocks, which form a ring. A movable connecting assembly is provided between any two adjacent clamping blocks to movably connect the two adjacent clamping blocks. Any two adjacent clamping blocks can move closer or further away from each other in a direction perpendicular to the radial direction of the pipe body. The movable connecting assembly drives the two adjacent clamping blocks to move closer to each other in a direction perpendicular to the radial direction of the pipe body and abut against the pipe body.

[0007] Compared with the prior art, the present invention has the following advantages: By employing a clamping assembly movably mounted on a base to clamp the pipe body, the clamping assembly moves in the same direction as the pipe's axial direction, and a buffer spring is provided on the base to abut against the clamping assembly. When the pipe body moves along its axial direction during steam transport, the clamping assembly actuates accordingly, and the buffer spring's extension and contraction provide cushioning. The clamping assembly consists of multiple clamping blocks arranged in a ring, and a movable connecting assembly connects any two adjacent clamping blocks. Adjacent clamping blocks can move closer or further apart in a direction perpendicular to the pipe body's radial direction while being driven by the movable connecting assembly. The clamping blocks are brought close together to keep them in contact with the pipe body and fix the pipe body in position on the clamping assembly. When the pipe body moves radially along the pipe body during steam transportation, the clamping blocks move with the vibration of the pipe body to reduce the impact force generated by the collision between the pipe body and the clamping blocks. At the same time, the clamping blocks are kept in contact with the pipe body under the action of the movable connecting assembly to keep the position of the pipe body stable. This solves the technical problem of steam pipe vibration causing deformation or damage to parts of the steam pipe. It has the technical effect of extending the service life of the pipe body and avoiding deformation of the pipe body or damage to other parts, which helps to reduce safety hazards and ensure the normal operation of steam transportation.

[0015] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] like Figures 1 to 6 As shown in the figure, an embodiment of the present invention proposes a steam conveying vibration damping pipe for conveying high-temperature and high-pressure steam.

[0017] Please refer to Figure 1 and Figure 2The steam conveying vibration damping pipe includes a base 1 and a pipe body 2 disposed on the base 1. The pipe body 2 is used to transport steam, and the base 1 is used to support the pipe body 2. The base 1 is provided with a sliding groove 11, and a movable clamping assembly 3 is provided in the sliding groove 11. The clamping assembly 3 is used to cooperate with the pipe body 2 to hold the pipe body 2 on the base 1. The moving direction of the clamping assembly 3 is consistent with the axial direction of the pipe body 2. The sliding groove 11 is also provided with a plurality of buffer springs 12, and the opposite ends of the buffer springs 12 in the extension direction respectively abut against the opposite sides of the clamping assembly 3. The extension and retraction direction of the buffer spring 12 is consistent with the axial direction of the pipe body 2; the clamping assembly 3 includes a plurality of clamping blocks 31, which are arranged in a ring and a movable connecting assembly 4 is provided between any two adjacent clamping blocks 31 to movably connect the adjacent clamping blocks 31. Any two adjacent clamping assemblies 3 can move closer or further away from each other in a direction perpendicular to the radial direction of the pipe body 2, and the movable connecting assembly 4 is used to drive the two adjacent clamping blocks 31 to move closer to each other in a direction perpendicular to the pipe body 2, so that the clamping blocks 31 are kept in contact with the pipe body 2 to position the pipe body 2.

[0018] Specifically, when the pipe body 2 vibrates during the steam transportation process using the steam conveying vibration damping pipeline provided in this embodiment, when the pipe body 2 moves along its axial direction, the clamping assembly 3 moves within the slide groove 11 as the pipe body 2 moves. Simultaneously, the buffer spring 12 extends and retracts with the movement of the clamping assembly 3 to buffer the movement of the pipe body 2 and prevent the pipe body 2 from colliding with the clamping assembly 3. When the pipe body 2 moves radially, some of the clamping blocks 31 move with the vibration of the pipe body 2 under the push of the pipe body 2. The movable connecting assembly 4 keeps adjacent clamping blocks 31 connected while abutting against the pipe body 2, reducing the impact force generated by the collision between the pipe body 2 and the clamping blocks 31, and keeping the position of the pipe body 2 stable. The steam conveying shock-absorbing pipe provided in this embodiment can prevent the pipe body 2 from colliding with the clamping assembly 3 during steam transportation, which would cause the pipe to deform or other parts to be damaged. This helps to extend the service life of the pipe body 2 and reduce safety hazards, ensuring that steam conveying operations can proceed normally.

[0019] like Figure 2 , Figure 3 and Figure 4As shown, the clamping assembly 3 also includes a movable seat 32, which fits against the inner wall of the slide groove 11, and one of the clamping blocks 31 is disposed on the movable seat 32. By connecting the movable seat 32 to one of the clamping blocks 31, and by sequentially connecting each clamping block 31 by the movable connecting assembly 4, the multiple clamping blocks 31 can maintain a complete ring shape on the base 1. The movement of the movable seat 32 within the slide groove 11 drives the clamping blocks 31 to slide synchronously along the axial direction of the pipe body 2 to prevent the clamping blocks 31 from disengaging from each other when the clamping assembly 3 is in operation, thereby improving the overall stability of the clamping assembly 3.

[0020] In detail, the base 1 is further provided with a bending portion 13, and the bending portions 13 are respectively provided on opposite sides of the slide groove 11. The bending portions 13 are in contact with the side of the movable seat 32 away from the slide groove 11. The bending portions 13 on the base 1 are provided to fit with the side of the movable seat 32 away from the slide groove 11 so that the movable seat 32 is held on the base 1, avoiding unexpected displacement of the movable seat 32 during movement that would cause the movable seat 32 to detach from the base 1.

[0021] Please combine Figure 2 and Figure 4 The base 1 is also provided with a detachable baffle 14. The baffle 14 is provided at opposite ends of the slide groove 11, and the baffle 14 closes the openings at both ends of the slide groove 11. The opposite ends of some of the buffer springs 12 in the extension direction abut against the movable seat 32 and the baffle 14 respectively. The baffle 14 is used to close the openings at both ends of the slide groove 11. After the movable seat 32 is installed into the slide groove 11, the baffle 14 is installed to keep the movable seat 32 in the slide groove 11, which facilitates the assembly of the clamping assembly 3. The opposite ends of some of the buffer springs 12 in the extension direction abut against the movable seat 32 and the baffle 14 respectively, so that some of the buffer springs 12 are kept between the movable seat 32 and the baffle 14 so that the buffer springs 12 can perform normal extension and contraction.

[0022] Specifically, a guide rod 15 is provided within the slide groove 11. The axial direction of the guide rod 15 is consistent with the axial direction of the pipe body 2, and the movable seat 32 is provided with a guide hole 33 that mates with the guide rod 15. Buffer springs 12 are respectively sleeved on the guide rod 15. The guide rod 15 within the slide groove 11 guides the movable seat 32 to move within the slide groove 11, preventing the movable seat 32 from deviating from a preset direction during movement. Furthermore, the buffer springs 12, respectively sleeved on the guide rod 15, keep the buffer springs 12 in contact with the movable seat 32, ensuring a stable fit between the buffer springs 12 and the movable seat 32.

[0023] like Figure 1 As shown, in this embodiment, the base 1 is provided with two clamping components 3 spaced apart, and the base 1 is provided with two sliding grooves 11 that correspond one-to-one with the clamping components 3. By clamping the pipe body 2 with the two clamping components 3 respectively, the reliability of the connection between the pipe body 2 and the base 1 can be improved, and the two clamping components 3 can move independently in the corresponding sliding grooves 11 to avoid the pipe body 2 from colliding with any one of the clamping components 3 and causing damage to the pipe body 2.

[0024] like Figure 4 , Figure 5 and Figure 6 As shown, the movable connection assembly 4 includes an insert plate 41 and a mounting plate 42 detachably connected to the insert plate 41. The insert plate 41 and the mounting plate 42 form a frame. Two adjacent clamping blocks 31 are provided with slots 34 at their ends that allow part of the insert plate 41 to pass through. The portions of the insert plate 41 that extend into the two slots 34 are provided with movable push plates 43 and drive springs 44 that abut against the push plates 43. The direction of movement of the push plates 43 is perpendicular to the radial direction of the pipe body 2. The drive springs 44 drive the two push plates 43 to move closer to each other and abut against the clamping blocks 31 respectively. Inserting the insert plate 41 into the slots 34 on two adjacent clamping blocks 31 and combining the mounting plate 42 with the insert plate 41 allows the insert plate 41 to be held on the clamping block 31. After the insert plate 41 is inserted into the slot 34, the push plate 43 abuts against the push block under the drive spring 44. Under the action of the drive spring 44, the two push plates 43 push the two adjacent clamping blocks 31 closer to each other to clamp the pipe body 2. When the clamping block 31 moves with the vibration of the pipe body 2, the drive spring 44 extends and retracts to keep the clamping block 31 engaged with the pipe body 2, preventing the clamping block 31 from disengaging from the pipe body 2 when it vibrates, thus improving the reliability of the engagement between the clamping assembly 3 and the pipe body 2.

[0025] In detail, the push plate 43 is provided with a movable rod 45, the axial direction of which is perpendicular to the radial direction of the pipe body 2, and the insert plate 41 is provided with a through hole that mates with the movable rod 45. The drive spring 44 is sleeved on the movable rod 45. The movable rod 45 is used to limit the movement direction of the push plate 43 on the insert plate 41, so that the push plate 43 remains in contact with the clamping block 31 in the slot 34. Furthermore, by sleeved on the movable rod 45, the opposite ends of the drive spring 44 in the extension and retraction direction remain in contact with the insert plate 41 and the push plate 43, preventing the drive spring 44 from disengaging from the push plate 43 during its movement.

[0026] Please refer to Figure 6 To facilitate the assembly of the insert plate 41 and the mounting plate 42 into one unit, the insert plate 41 has a mounting part 46 and the mounting plate 42 is provided with a mounting groove 47 that cooperates with the mounting part 46. The mounting part 46 is provided with a first mounting hole 48 and the mounting plate 42 is provided with a second mounting hole 49 that is aligned with the first mounting hole 48. The mounting plate 42 is also provided with a threaded connector 5 that passes through the first mounting hole 48 and the second mounting hole 49. The mounting part 46 is provided on the insert plate 41, and the mounting groove 47 for accommodating the mounting part 46 is provided on the mounting plate 42. The mounting part 46 can be easily inserted into the mounting groove 47 to align the insert plate 41 and the mounting plate 42. After the mounting plate 42 and the mounting groove 47 are engaged, the first mounting hole 48 and the second mounting hole 49 are aligned. At this time, the mounting plate 42 can be fixed on the insert plate 41 by inserting the threaded connector 5 into the first mounting hole 48 and the second mounting hole 49, and the connection between the insert plate 41 and the mounting plate 42 can be ensured to be stable.

[0027] Specifically, when using the movable connecting assembly 4 provided in this embodiment to connect two adjacent clamping blocks 31, first press the push plate 43 to bring it close to the insert plate 41, then insert the insert plate 41 into the corresponding slot 34 and release the push plate 43. At this time, the push plate 43 abuts against the clamping block 31 under the drive of the drive spring 44, pushing the push plate 43 so that the mounting part 46 on the push plate 43 completely passes through the slot 34. Then, the mounting plate 42 is engaged with the mounting part 46 and the threaded connector 5 is tightened to complete the assembly of the movable connecting assembly 4 and realize the movable connection of the two clamping blocks 31. Furthermore, when assembling the steam conveying vibration damping pipe provided in this embodiment, the pipe body 2 is first placed on the clamping block 31 located on the movable seat 32, and then the clamping block 31 is connected by the movable connecting component 4 to complete the combination of the clamping component 3. Alternatively, the clamping blocks 31 can be connected in sequence and then the clamping blocks 31 can be pulled to make the clamping blocks 31 move away from each other and the pipe body 2 can be inserted into the ring formed by the clamping blocks 31. The operation is simple.

[0028] like Figure 3 and Figure 4 As shown, to further prevent damage to the pipe body 2 or the clamping assembly 3 when the pipe body 2 collides with the clamping block 31, the clamping block 31 is provided with a receiving groove on the side near the pipe body 2. An elastic support block 35 is provided within the receiving groove. The elastic support block 35 abuts against the outer peripheral wall of the pipe body 2, and the side of the elastic support block 35 near the pipe body 2 has a positioning slope 36. The clamping block 31 directly contacts the pipe body 2 through the elastic support block 35 located in the receiving groove. The elastic support block 35 is made of elastic materials such as silicone or rubber. During the vibration of the pipe body 2, the elastic support block 35 vibrates synchronously with the pipe body 2, effectively preventing scratches on the surface of the pipe body 2. The positioning slope 36 is provided on the elastic support block 35 to facilitate the insertion of the pipe body 2 into the ring formed by the clamping block 31 during the assembly of the steam conveying vibration-damping pipe.

[0029] like Figure 2 and Figure 4As shown, in this embodiment, the pipe body 2 includes a conveying inner wall layer 21, an insulation layer 22, and a protective layer 23 arranged sequentially from the inside out. The clamping blocks 31 abut against the protective layer 23. The insulation layer 22 can be made of insulation cotton or aerogel to reduce heat loss during steam transportation. The protective layer 23 can be made of metal or rubber materials. The protective layer 23 protects the inner conveying inner wall layer 21 from damage when the pipe body 2 is subjected to external impact, thus ensuring the normal operation of steam transportation.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
