Description

Technical Field

[0001] This utility model relates to the field of pipeline compensator technology, and in particular to a shock-absorbing compensator for S-type metal pipelines. Background Technology

[0002] Pipeline compensators are key flexible pressure-bearing components installed in various pipeline systems. They are based on a flexible pressure-bearing structure and absorb displacement and deformation caused by temperature changes (thermal expansion and contraction), installation deviations, medium pressure fluctuations, or equipment vibrations through their own elastic deformation or displacement compensation capabilities. This releases pipeline system stress and prevents pipeline weld cracking, flange leakage, or overload damage to related equipment interfaces.

[0003] Currently, existing pipeline compensators generally use metal bellows as the core elastic component, combined with pipe connections, flanges, and flow guides, and are mainly used for displacement compensation in pipeline systems. When used in S-shaped pipelines, because S-shaped pipelines have multiple bends, vibration energy tends to accumulate at the bends. Existing compensators have poor vibration reduction capabilities and cannot effectively absorb and disperse the concentrated vibration energy at the bends. This leads to fatigue damage after the compensator has been subjected to concentrated vibration loads for a long time, thus affecting its service life and the stability of the pipeline system. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose an S-type metal pipeline vibration damping compensator, which effectively absorbs and disperses the vibration energy at the corner by setting a compensation mechanism and a vibration damping mechanism at the corner, thereby reducing fatigue damage of the compensation mechanism, improving the service life of the compensator and the stability of the pipeline system.

[0006] To achieve the above objectives, this utility model proposes an S-type metal pipe vibration damping compensator, comprising two connecting pipes, a lateral compensation component, and two corner vibration damping compensation mechanisms. Each connecting pipe has a first flange at both ends. The adjacent ends of the two corner vibration damping compensation mechanisms are located at both ends of the lateral compensation component. Each corner vibration damping compensation mechanism includes a corner compensation component, multiple sets of damping components, and two arc-shaped tie rods. The corner compensation component is connected to the connecting pipe via the first flange. The two arc-shaped tie rods are symmetrically arranged on the corner compensation component. The multiple sets of damping components are equidistantly arranged on the two arc-shaped tie rods, with their movable ends abutting against the corner compensation component.

[0007] In addition, the S-type metal pipe vibration damping compensator proposed above according to this utility model may also have the following additional technical features: Specifically, the lateral compensation assembly includes two second flanges, fastening rods, three connecting seats, and a lateral bellows. The two second flanges are symmetrically arranged on the lateral bellows, and the three connecting seats are arranged on the second flanges and are equidistantly distributed along the edges of the second flanges. The two corresponding connecting seats in the horizontal direction are connected by the fastening rods.

[0008] Specifically, the corner compensation assembly includes a corner bellows, two third flanges, and two limiting seats, wherein the two third flanges are symmetrically arranged on the corner bellows, and the two limiting seats are symmetrically arranged on the third flanges.

[0009] Specifically, the two third flanges are connected to the first flange and the second flange respectively by fasteners.

[0010] Specifically, the shock absorption assembly includes a buffer pad, a support ring, an elastic element, two guide rods, a damping rod, a drive plate, a connecting frame, and a threaded rod. The buffer pad is disposed inside the support ring, the two guide rods are symmetrically disposed on the support ring, the drive plate and the connecting frame are slidably disposed on the two guide rods, the two ends of the damping rod are respectively disposed on the support ring and the drive plate, the elastic element is sleeved on the damping rod and its two ends abut against the support ring and the drive plate respectively, and the threaded rod is threaded inside the connecting frame and its end is rotatably connected to the drive plate.

[0011] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: This invention, by setting up a corner damping and compensation mechanism, can form a support and vibration reduction system at the corner position. During operation, the corner compensation component performs initial compensation through its own elastic deformation capability. Then, with the cooperation of multiple damping components, the damping rod and elastic element can further consume and absorb vibration energy, effectively reducing the fatigue damage to the corner bellows caused by energy concentration at the corner. It achieves effective dispersion and absorption of vibration energy at the corner, significantly improving the overall stability and durability of the pipeline system.

[0015] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0016] The following describes an embodiment of the S-type metal pipe vibration damping compensator with reference to the accompanying drawings.

[0017] like Figures 1-5 As shown in the figure, an S-type metal pipe vibration damping compensator according to an embodiment of the present invention includes two connecting pipes 1, a lateral compensation component 3 and two corner vibration damping compensation mechanisms, wherein a first flange 2 is provided at both ends of the connecting pipe 1.

[0018] It should be noted that the two connecting pipes 1 are vertically parallel pipes used to connect the S-type metal pipe vibration damping compensator to the pipeline system, serving as a connection.

[0019] The adjacent ends of the two corner damping compensation mechanisms are set at both ends of the transverse compensation component 3. Each corner damping compensation mechanism includes a corner compensation component 4, multiple sets of damping components 5 and two arc-shaped tie rods 6. The corner compensation component 4 is connected to the connecting pipe 1 through the first flange 2. The two arc-shaped tie rods 6 are symmetrically arranged on the corner compensation component 4. The multiple sets of damping components 5 are equidistantly arranged on the two arc-shaped tie rods 6, and their movable ends abut against the corner compensation component 4.

[0020] It should be noted that the overall structure of the vibration damping compensator is S-shaped. In an S-shaped pipeline system, due to the presence of multiple corners, vibration energy tends to accumulate at the corners. Therefore, the vibration damping compensator for S-shaped metal pipelines can effectively absorb and disperse this vibration energy concentrated at the corners.

[0021] Specifically, the two corner damping compensation mechanisms are respectively set at the corner positions. The two arc-shaped tie rods 6 can form a stable support structure, providing an installation base for the damping component 5. The corner compensation component 4 can compensate to a certain extent through its own elastic deformation capacity. At the same time, with the cooperation of multiple damping components 5, the vibration energy can be further dispersed and absorbed, avoiding energy concentration that could cause fatigue damage to the corner compensation component 4.

[0022] In one embodiment of this utility model, such as Figure 2 As shown, the transverse compensation assembly 3 includes two second flanges 31, fastening rods 32, three connecting seats 33, and a transverse bellows 34. The two second flanges 31 are symmetrically arranged on the transverse bellows 34, and the three connecting seats 33 are arranged on the second flanges 31 and are equidistantly distributed along the edge of the second flanges 31. The two corresponding connecting seats 33 in the horizontal direction are connected by fastening rods 32.

[0023] It should be noted that the connecting seat 33 is fixedly installed on the second flange 31, and the two second flanges 31 are symmetrically fixedly installed on the transverse bellows 34. The fastening tie rod 32 is connected to the corresponding two connecting seats 33 by bolts, thereby enhancing the overall structural strength of the transverse compensation component 3, so that it can maintain a stable working state when subjected to transverse displacement caused by temperature changes, medium pressure fluctuations, etc. in the pipeline system.

[0024] Specifically, the transverse corrugated pipe 34, as a core elastic component, can absorb and compensate for the horizontal displacement of the pipeline system by utilizing its own elastic deformation capability, effectively releasing the stress of the pipeline system.

[0025] In one embodiment of this utility model, such as Figure 3-4As shown, the corner compensation assembly 4 includes a corner bellows 41, two third flanges 42 and two limiting seats 44. The two third flanges 42 are symmetrically arranged on the corner bellows 41, and the two limiting seats 44 are symmetrically arranged on the third flanges 42. The two third flanges 42 are connected to the first flange 2 and the second flange 31 respectively by fasteners.

[0026] It should be noted that the two third flanges 42 are symmetrically fixed at both ends of the corner bellows 41, the limit seat 44 is fixedly installed on the third flange 42, and the two ends of the arc-shaped tie rod 6 are fixedly installed on the corresponding two limit seats 44 by bolts, thereby firmly connecting the arc-shaped tie rod 6 with the corner compensation component 4.

[0027] Two third flanges 42 are fixedly connected to the first flange 2 and the second flange 31 respectively by bolts, thereby connecting the connecting pipe 1, the corner corrugated pipe 41 and the transverse corrugated pipe 34 to form an S-shaped pipeline compensation structure, ensuring that when the pipeline system is displaced, the components can work together to effectively absorb and compensate for the displacement.

[0028] Understandably, the corner corrugated pipe 41, as the core elastic component of the corner compensation assembly 4, can use its own elastic deformation capability to compensate for the displacement caused by temperature changes, medium pressure fluctuations, etc. at the corner.

[0029] In one embodiment of this utility model, such as Figures 4-5 As shown, the shock absorption assembly 5 includes a buffer pad 51, a support ring 52, an elastic element 53, two guide rods 54, a damping rod 55, a drive plate 56, a connecting frame 57, and a threaded rod 58. The buffer pad 51 is disposed inside the support ring 52. The two guide rods 54 are symmetrically disposed on the support ring 52. The drive plate 56 and the connecting frame 57 are slidably disposed on the two guide rods 54. The two ends of the damping rod 55 are respectively disposed on the support ring 52 and the drive plate 56. The elastic element 53 is sleeved on the damping rod 55, and its two ends abut against the support ring 52 and the drive plate 56 respectively. The threaded rod 58 is threadedly disposed inside the connecting frame 57, and its end is rotatably connected to the drive plate 56.

[0030] It should be noted that the buffer pad 51 is bonded to the inner wall of the support ring 52. The support ring 52 is attached to the annular protrusion of the corner corrugated pipe 41 through the buffer pad 51, which plays a preliminary buffering and protection role. The buffer pad 51 is made of rubber.

[0031] Two guide rods 54 are fixedly installed on the support ring 52, which can guide the drive plate 56 and the support ring 52. The two ends of the damping rod 55 are respectively installed on the support ring 52 and the drive plate 56. The elastic element 53 is a spring, and its two ends abut against the support ring 52 and the drive plate 56 respectively.

[0032] Understandably, when the pipeline system vibrates, the vibration energy is transmitted to the support ring 52 through the buffer pad 51. The buffer pad 51 initially buffers the vibration energy. After receiving the vibration energy, the support ring 52 displaces along the direction of the two guide rods 54. At this time, the damping rod 55 provides damping force, consuming part of the vibration energy. The elastic element 53 simultaneously undergoes elastic deformation, further absorbing and dispersing the vibration energy. In turn, through the cooperation of multiple sets of vibration damping components 5, the vibration energy can be effectively dispersed and absorbed, avoiding energy concentration at corners. This reduces fatigue damage to components such as the corner compensation component 4, and improves the service life of the entire S-type metal pipeline vibration damping compensator and the stability of the pipeline system.

[0033] It should be noted that the threaded rod 58 is threaded inside the connecting frame 57, and its end is rotatably mounted inside the drive plate 56. When the threaded rod 58 rotates, it will drive the drive plate 56 to move along the direction of the guide rod 54, thereby changing the compression of the elastic element 53 and adjusting the damping stiffness of the damping component 5. This allows the damping component 5 to be flexibly adjusted according to the actual working conditions and vibration characteristics to adapt to vibrations of different frequencies and amplitudes and improve the damping effect.

[0034] In practical applications, the connecting pipe 1 is connected to the pipeline system, and then the various components are assembled and fixed by fasteners. When liquid flows through the pipeline, the pipeline system will vibrate and displace due to factors such as liquid flow and temperature changes. At this time, the transverse corrugated pipe 34 uses its elastic deformation ability to absorb and compensate for the horizontal displacement of the pipeline system and release the stress of the pipeline system. The corner corrugated pipe 41 compensates for the displacement caused by temperature changes and medium pressure fluctuations at the corner.

[0035] When the corner bellows 41 compensates for the displacement at the corner, the energy generated by the vibration at the corner will be transmitted to the damping component 5. At this time, the buffer pad 51 first buffers the vibration energy, and then the support ring 52 displaces and squeezes the damping rod 55. The damping rod 55 consumes part of the vibration energy, and the elastic element 53 simultaneously undergoes elastic deformation to further absorb and disperse the vibration energy.

[0036] Furthermore, through the cooperation of multiple sets of vibration damping components 5, vibration energy can be effectively dispersed and absorbed, preventing energy from concentrating at corners, reducing fatigue damage to components such as corner compensation components 4, and effectively improving the stability and service life of the pipeline system.

[0037] In summary, the S-type metal pipe vibration damping compensator of this utility model embodiment, by setting two corner vibration damping compensation mechanisms, can form a stable support and vibration reduction system at the corner position. During operation, the corner compensation component performs initial compensation through its own elastic deformation capability. Then, with the cooperation of multiple sets of vibration damping components, the damping rod and elastic element can further consume and absorb vibration energy, effectively reducing the fatigue damage caused to the corner bellows by energy concentration at the corner, realizing the effective dispersion and absorption of vibration energy at the corner, and significantly improving the overall stability and durability of the pipeline system.
