[0042] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.
[0043] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.
[0044] In one embodiment of the present invention, Figure 1 The pipeline vibration absorber comprises: an elastic component 100 and a mass component 200;
[0045] The elastic component 100 is used for sleeve installation of pipelines; the mass component 200 is sleeved on the elastic component 100 .
[0046] In this embodiment, the pipeline vibration absorber is provided with an elastic component 100 and a mass component 200, wherein the elastic component 100 is used to be sleeved on the pipeline, and the mass component 200 is sleeved on the elastic component 100. Through such a configuration, the elastic component 100 is sleeved on the pipeline, the elastic component 100 is annular, and the structure is close to axisymmetric, and the stiffness in any radial direction of the elastic component 100 can be kept consistent, and the mass component 200 is sleeved on the elastic component 100, the mass component 200 is annular, and the structure is close to axisymmetric, and the mass in any radial direction of the mass component 200 can be kept consistent, and thus the stiffness and mass characteristics of the pipeline vibration absorber are close to axisymmetric, and the pipeline vibration absorber can have consistent vibration absorption performance in any direction of the pipeline path, thereby reducing the line spectrum vibration of the pipeline path in any direction to meet the vibration reduction of the pipeline.
[0047] The natural frequency value of the pipeline vibration absorber is designed according to the pipeline diameter, prominent line spectrum frequency, and target vibration absorption effect, and the dimensions of the elastic component 100 and the mass component 200 are designed. The natural frequency of the pipeline vibration absorber is tested after assembly, and the dimensions of the mass component 200 are adjusted until the natural frequency of the pipeline vibration absorber accurately matches the design value.
[0048] In one embodiment of the present invention, Figure 1 As shown, the pipeline vibration absorber further includes: an adjustment component 300 and a fixing component 400;
[0049] The adjusting component 300 is used to be sleeved between the elastic component 100 and the pipeline; the fixing component 400 is sleeved between the elastic component 100 and the adjusting component 300.
[0050] In this embodiment, the pipeline vibration absorber is further provided with an adjusting component 300 and a fixing component 400, wherein the adjusting component 300 is directly sleeved on the pipeline, and the fixing component 400 is sleeved between the elastic component 100 and the adjusting component 300. The reason for such a configuration is that errors are inevitable when the pipeline is manufactured, which will cause gaps in the connection between the pipeline vibration absorber and the pipeline. While the connection is unstable, the vibration reduction effect is reduced, and it is difficult to ensure that the vibration of the pipeline path in any direction is absorbed. The adjusting component 300 is in the shape of a circular ring, and the inner diameter of the adjusting component 300 matches the standard outer diameter of the pipeline. By wrapping the adjusting component 300 around the outer diameter of the pipeline, the manufacturing error of the outer diameter of the pipeline can be effectively adapted. By sleeved the fixing component 400 on the outer diameter of the adjusting component 300, the pipeline vibration absorber can be fixed on the pipeline without gaps and the connection is firm, which improves the stability of the pipeline vibration absorber and further ensures the vibration absorption effect of the pipeline vibration absorber on the vibration generated by the pipeline path in any direction.
[0051] In one embodiment of the present invention, the adjustment assembly 300 is in the shape of a ring with an opening, and the opening is used to install the adjustment assembly 300 on the pipeline.
[0052] In this embodiment, the adjustment component 300 is in a circular shape, and the side of the adjustment component 300 has an opening. It can be understood that the adjustment component 300 has a certain elasticity. The opening is enlarged by stretching until the size of the opening matches the size of the pipeline. The adjustment component 300 is installed on the pipeline through the opening. Such a configuration facilitates the installation of the adjustment component 300, reduces the difficulty of processing, and the adjustment component 300 is not easy to fall off the pipeline.
[0053] In one embodiment of the present invention, the adjustment assembly 300 includes two or more than three adjustment parts 310 , and all the adjustment parts 310 can form a first circular ring 320 , and the first circular ring 320 is used for sleeve installation of pipelines.
[0054] In this embodiment, if Figure 2 As shown, the adjustment assembly 300 is composed of two or more adjustment parts 310, and all the adjustment parts 310 together can form a first ring 320, and the first ring 320 is sleeved on the pipeline. It can be understood that all the adjustment parts 310 have a certain elasticity, and each adjustment part 310 has a certain curvature. The inner diameter size of the adjustment part 310 matches the outer diameter size of the pipeline, so that the first ring 320 can fit the outer diameter of the pipeline well and effectively adapt to the manufacturing error of the outer diameter of the pipeline.
[0055] In one embodiment, the adjustment assembly 300 is composed of two adjustment parts 310, and each adjustment part 310 is semi-circular. The two adjustment parts 310 form a first circular ring 320 and are sleeved on the pipeline, thereby reducing the number of docking surfaces, so that the influence of the docking surfaces on the vibration absorption effect of the pipeline vibration absorber can be ignored.
[0056] In one embodiment of the present invention, the adjustment component 300 is made of rubber.
[0057] In this embodiment, the adjustment component 300 is made of a rubber material with good elasticity and vibration absorption effects, so that the connection between the adjustment component 300 and the pipeline is tightened and easy to install. The rubber material can fit well into the gaps in the pipeline caused by manufacturing errors, further improving the vibration absorption effect of the pipeline vibration absorber on any direction of the pipeline.
[0058] In one embodiment of the present invention, the fixing assembly 400 includes: two or more fixing parts 410,
[0059] All the fixing parts 410 can form a second ring 420, and the second ring 420 is sleeved on the adjustment component 300; connecting bosses 430 are respectively provided at both ends of the fixing parts 410, and the corresponding positions of the connecting bosses 430 of two adjacent fixing parts 410 are provided with first connecting through holes 440.
[0060] In this embodiment, if Figure 3 As shown, the fixing assembly 400 is composed of two or more fixing parts 410, and all the fixing parts 410 together can form a second ring 420, and the second ring 420 is sleeved on the outer diameter of the adjustment assembly 300, and connecting bosses 430 are respectively provided at both ends of the fixing part 410, and a first connecting through hole 440 is provided at the corresponding position of each two adjacent bosses. In this way, when two adjacent fixing parts 410 are connected, the bosses are also connected, and the first connecting through holes 440 on the bosses correspond to each other. By passing the bolts through the two first connecting through holes 440, the two adjacent fixing parts 410 can be bolted together, so that the connection between the fixing parts 410 is tightened, and it is easy to install and disassemble, thereby improving efficiency.
[0061] In one embodiment, the fixing assembly 400 is composed of two fixing parts 410, and each fixing part 410 is semi-circular. The two fixing parts 410 form a second circular ring 420 and are sleeved on the adjustment assembly 300, thereby reducing the number of docking surfaces and bosses, making the fixing effect of the fixing assembly 400 more stable and saving material costs.
[0062] In one embodiment of the present invention, the fixing assembly 400 includes: two or more fixing parts 410,
[0063] All the fixing parts 410 can form a second circular ring 420, and the second circular ring 420 is sleeved on the adjustment component 300; the corresponding positions of each two adjacent fixing parts 410 are provided with first step teeth 450, and the first step teeth 450 can bite each other; the bite position of the first step teeth 450 is provided with a second connecting through hole 460, and the edge of the second connecting through hole 460 away from the adjustment component 300 is provided with a chamfer 500.
[0064] In this embodiment, if Figure 4 As shown, the fixing assembly 400 is composed of two or more fixing parts 410, and all the fixing parts 410 together can form a second ring 420, the second ring 420 is sleeved on the outer diameter of the adjustment assembly 300, and a first step tooth 450 is provided at the corresponding position of each two adjacent fixing parts 410, and a second connecting through hole 460 is provided at the bite of the first step tooth 450. In this way, when two adjacent fixing parts 410 are connected, the first step teeth 450 bite each other to perform a preliminary alignment connection, and the second connecting through holes 460 at the bite of the first step teeth 450 correspond to each other. By passing the bolts through the two second connecting through holes 460, the two adjacent fixing parts 410 can be bolted together, thereby saving the axial space of the fixing assembly 400 and improving the application range of the pipeline shock absorber.
[0065] A chamfer 500 is provided at the edge of the second connecting through hole 460 away from the adjusting assembly 300 , so that when the bolt passes through the second connecting through hole 460 , it can be seated at the chamfer 500 , saving radial space of the fixing assembly 400 .
[0066] In one embodiment, the fixing assembly 400 is composed of two fixing parts 410, and each fixing part 410 is semi-circular. The two fixing parts 410 form a second ring 420 and are sleeved on the adjustment assembly 300, thereby reducing the number of docking surfaces and the first step teeth 450, making the fixing effect of the fixing assembly 400 more stable and saving material costs.
[0067] In one embodiment of the present invention, the elastic component 100 includes: two or more elastic parts 110 , all the elastic parts 110 can form a third ring 130 , and the third ring 130 is sleeved on the fixing component 400 .
[0068] In this embodiment, if Figure 5 As shown, the elastic component 100 is composed of two or more elastic parts 110, and all the elastic parts 110 together can form a third ring 130, and the third ring 130 is sleeved on the outer diameter of the fixed component 400. It can be understood that the elastic component 100 adopts a rubber material with good elastic effect and vibration absorption effect to improve the vibration absorption effect of the pipeline vibration absorber on any direction of the pipeline path.
[0069] In one embodiment, the elastic component 100 is composed of two elastic parts 110, and each elastic part 110 is semi-circular. The two elastic parts 110 form a third ring 130 and are mounted on the fixed component 400, thereby reducing the number of docking surfaces, making the stiffness difference of the docking surfaces negligible, and maintaining the stiffness of the elastic component 100 in any radial direction consistent.
[0070] In one embodiment, the elastic component 100 further includes: a support ring, which is disposed on the inner side and / or the outer side of the elastic component 100 .
[0071] In this embodiment, the elastic component 100 is also provided with a support ring, which is arranged on the inner side and / or outer side of the elastic component 100. The support ring is made of elastic metal material. The support ring can support the elastic component 100, so as to ensure that the stiffness of the elastic component 100 remains unchanged, thereby improving the stability of the pipeline vibration absorber. It can be understood that the support ring and the elastic component 100 are vulcanized as one piece, which reduces the influence of the connection interface between the elastic components 100 and the influence of the installation interface when the elastic component 100 is installed on the fixed component 400, thereby ensuring the vibration absorption effect of the pipeline vibration absorber on vibrations generated in any direction of the pipeline path.
[0072] In one embodiment, the mass assembly 200 includes: two or more mass parts 210,
[0073] All mass parts 210 can form a fourth ring 220, and the fourth ring 220 is sleeved on the elastic component 100; second step teeth 230 are provided at corresponding positions of each two adjacent mass parts 210, and the second step teeth 230 can bite each other; a third connecting through hole 240 is provided at the biting position of the second step teeth 230, and a chamfer 500 is provided on the edge of the end of the third connecting through hole 240 away from the elastic component 100.
[0074] In this embodiment, if Figure 6 As shown, the mass component 200 is composed of two or more mass parts 210, and all the mass parts 210 together can form a fourth ring 220, the fourth ring 220 is sleeved on the outer diameter of the elastic component 100, and a second step tooth 230 is arranged at the corresponding position of each two adjacent mass parts 210, and a third connecting through hole 240 is arranged at the bite of the second step teeth 230.

[0075] A chamfer 500 is provided at the edge of the third connecting through hole 240 away from the elastic component 100 , so that when the bolt passes through the third connecting through hole 240 , it can be seated at the chamfer 500 , saving radial space of the fixing component 400 .
[0076] In one embodiment, the mass component 200 is composed of two mass parts 210, and each mass part 210 is semi-circular.
