Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline vibration and noise technology, and in particular to an elastic caving component. Background Technology
[0002] Elastic through-hull fittings are pipe accessories fixed to the bulkhead structure and used to connect pipes on both sides of the bulkhead. Pipe vibration is transmitted to the bulkhead structure through the through-hull fittings, which in turn can cause hull vibration. Existing through-hull fittings are usually rigidly welded to the bulkhead structure and have little ability to isolate pipe vibration or compensate for displacement. When the pipes are displaced due to thermal expansion and contraction, hull deformation or equipment vibration, the pipes are forced to bear additional tensile, compressive or shear stress, which can cause cracks or even breakage at the connection between the pipes and the through-hull fittings. Utility Model Content
[0003] The purpose of this invention is to provide an elastic through-chamber component for supporting through-chamber pipelines and for reinforcing the chamber wall, sealing the compartment, and bearing pressure at the through-chamber location. It also attenuates the vibration transmitted from the through-chamber pipeline to the chamber wall and has elastic compensation functions for large axial and radial displacements.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an elastic tank-penetrating component, including a welded cylinder, a liquid-passing pipe assembly passing through the welded cylinder, the welded cylinder being located in the middle of the liquid-passing pipe assembly, and first flanges and vulcanizing components symmetrically sleeved on both sides of the liquid-passing pipe assembly, the liquid-passing pipe assembly including a liquid-passing pipe body, two first flanges being detachably connected to both ends of the liquid-passing pipe body, and two vulcanizing components being detachably connected to both ends of the welded cylinder respectively.
[0005] The liquid passage assembly also includes a second buffer ring, which is fixedly sleeved in the middle of the liquid passage body. A first protrusion, a first buffer ring, and a second protrusion are symmetrically fixedly arranged on the liquid passage body on both sides of the second buffer ring. The first buffer ring is fixedly connected to the side of the first protrusion close to the second buffer ring, and an anti-collision layer is fixedly arranged on the outside of the second protrusion.
[0006] The vulcanization assembly includes an axial damping ring. A second flange is fixedly provided at one end of the axial damping ring near the welded cylinder, and an end cap is fixedly provided at the other end of the axial damping ring away from the welded cylinder. The axial damping ring extends and is laid on the surfaces opposite the second flange and the end cap.
[0007] By adopting the above technical solution, the second buffer ring is fixed in the middle of the liquid-passing pipe body, which can absorb the axial vibration energy of the pipe and reduce the pipe deformation caused by fluid impact or mechanical vibration; the first buffer ring is fixedly connected to the first protrusion to form a composite structure of "flexible buffer + rigid support". When the pipe is impacted by external force, the first buffer ring can alleviate the impact force through elastic deformation and reduce the direct damage to the liquid-passing pipe body; the anti-collision layer outside the second protrusion can effectively buffer external impact and protect the liquid-passing pipe body from mechanical damage.
[0008] The axial damping ring in the vulcanization assembly is laid on the opposite surface of the first flange and the end cover. It absorbs the axial vibration of the pipeline through its own elastic deformation, reducing the transmission of vibration to the cabin structure. The second flange connects to the welded cylinder, forming a dual mechanism of "rigid connection + flexible damping", which further suppresses the propagation of vibration along the pipeline.
[0009] The first flange and both ends of the liquid-passing pipe, as well as the vulcanizing assembly and both ends of the welded cylinder, are detachable, which facilitates later maintenance, replacement of the buffer assembly or the liquid-passing pipe, and reduces maintenance costs. The end cap of the vulcanizing assembly, the second flange, and the axial vibration damping ring are vulcanized as a single piece to ensure the sealing of the connection and prevent fluid leakage, while also simplifying the installation process.
[0010] The vulcanized components are connected to the welded cylinder to form a tight elastic sealing layer, which can adapt to the slight displacement caused by the thermal expansion and contraction of the pipeline and prevent sealing failure due to deformation; the axial damping ring extends to the flange surface, which can fill the flange connection gap and further improve the sealing performance.
[0011] The welded cylinder, first flange, vulcanization assembly, and buffer structure are all symmetrically arranged along the central axis of the liquid-passing pipe to ensure uniform load distribution in the axial and radial directions of the pipeline and avoid local stress concentration or pipeline deviation caused by uneven force.
[0012] A further feature of this invention is that the first flange is a threaded flange with a neck, and the outer walls at both ends of the liquid-conducting pipe are provided with threads, and the inner wall of the threaded flange with a neck engages with the threads on the outer walls at both ends of the liquid-conducting pipe.
[0013] By adopting the above technical solution, the neck structure of the threaded flange can increase the connection length between the first flange and the liquid pipe body, making the thread engagement length longer, thereby improving the stability of the connection, reducing the risk of leakage caused by loose connection, and ensuring the normal operation of the elastic penetration component.
[0014] The neck structure of the threaded flange wraps around the end of the liquid-passing pipe, which is equivalent to adding a layer of protection and support to the end of the liquid-passing pipe, enhancing the structural strength of the end of the liquid-passing pipe, and reducing the possibility of deformation or damage to the end of the liquid-passing pipe.
[0015] A further feature of this invention is that the outer side of the second flange is provided with a ring of threaded holes, and the welded cylinder is also provided with threaded holes at the corresponding positions of the threaded holes, with an included angle of 15 degrees between adjacent threaded holes.
[0016] By adopting the above technical solution, a series of threaded holes and screws can form a uniformly distributed fastening force between the vulcanizing component and the welded cylinder, avoiding local stress concentration caused by single-point force. The included angle between adjacent threaded holes is 15 degrees, that is, 24 holes are evenly distributed around the circumference, ensuring that the bolt spacing is consistent. After fastening, the connection plane between the vulcanizing component and the welded cylinder is subjected to uniform force, improving the stability of the overall structure.
[0017] A further feature of this invention is that a screw is inserted into a threaded hole, and a spring washer and a flat washer are sequentially arranged along the screw axis at the connection between the screw and the second flange, with the flat washer close to the second flange.
[0018] By adopting the above technical solution, the spring washer, through the tension generated by its own elastic deformation, continuously presses against the bolt and nut under vibration or impact load, counteracting the relative displacement between threads caused by vibration, effectively preventing the screw from loosening, and ensuring the long-term reliable connection between the vulcanized component and the welded cylinder; the flat washer can increase the contact area between the screw head and the surface of the second flange, avoiding the screw from directly pressing the flange surface and causing indentation or damage, while dispersing the screw tightening force, making the pressure evenly distributed, and indirectly enhancing the anti-loosening effect.
[0019] The flat gasket fits tightly against the surface of the second flange, filling in the minor unevenness around the threaded hole and reducing the sealing gap caused by surface unevenness. Together with the elastic sealing layer of the vulcanized component, it further improves the overall sealing performance of the passage section and prevents fluid leakage from the connection gap.
[0020] A further feature of this invention is that the welding cylinder is provided with an O-ring groove at the connection point with the vulcanizing component, and the end cap is also provided with an O-ring groove at the connection point with the liquid-passing pipe, with an O-ring provided in the O-ring groove.
[0021] By adopting the above technical solution, the O-ring has good elasticity. After being installed into the O-ring groove, it will generate a certain pre-tightening force on the contact surface, filling the tiny gaps in the connection. By setting O-rings at the connection positions of the welded cylinder and the vulcanization component, as well as the connection positions of the end cap and the liquid passage pipe, it can effectively prevent fluid from leaking from these connections and meet the requirements of compartment sealing and pressure bearing of the transom components.
[0022] A further feature of this invention is that the anti-collision layer is a 2 mm thick vulcanized rubber layer.
[0023] By adopting the above technical solution, the anti-collision layer is made of 2 mm thick vulcanized rubber. Utilizing its high elasticity and wear resistance, it can effectively buffer external impacts, absorb impact energy, protect the liquid passage pipe from mechanical damage, and improve the impact resistance of the penetration component.
[0024] A further feature of this invention is that the O-ring, axial damping ring, first buffer ring, and second buffer ring are all made of vulcanized rubber.
[0025] By adopting the above technical solution, the O-ring, axial damping ring, first buffer ring and second buffer ring are all made of vulcanized rubber, which can undergo flexible deformation with the thermal expansion and contraction of the pipeline or mechanical displacement. While maintaining the reliability of the connection, it allows for displacement compensation within a certain range, thereby improving the system's adaptability to complex working conditions.
[0026] The beneficial effects of this utility model are:
[0027] 1. The axial damping ring is made of vulcanized rubber and extends to the opposite surfaces of the second flange and end cap. It absorbs axial vibration and displacement of the pipeline through its own elastic deformation, reducing the transmission of vibration to the cabin structure. The second buffer ring is also made of vulcanized rubber and is fixed in the middle of the liquid-passing pipe. It can absorb axial vibration energy and allow the pipeline to undergo small axial displacement. The axial damping ring and the second buffer ring work together to form a flexible compensation mechanism, which can alleviate axial load and adapt to changes in working conditions. The maximum axial displacement compensation can reach 12 mm.
[0028] 2. The axial damping ring, the first buffer ring, and the second buffer ring are all made of vulcanized rubber, which has elastic deformation capability and can absorb radial vibration and displacement of the pipeline, and adapt to radial offset. The first protrusion, the first buffer ring, and the second protrusion symmetrically arranged on the liquid flow pipe form a "rigid support + flexible buffer" system, which allows the pipeline to deflect slightly around the central axis. At the same time, the anti-collision layer buffers external radial impact, and the maximum radial displacement compensation can reach 12 mm, and the angle deflection of ≤6° is allowed.
[0029] 3. The first flange and both ends of the liquid-passing pipe, as well as the vulcanizing assembly and both ends of the welded cylinder, are detachable, which facilitates later maintenance, replacement of the buffer assembly or the liquid-passing pipe, and reduces maintenance costs. The end cap of the vulcanizing assembly, the second flange and the axial vibration damping ring are vulcanized as a whole to ensure the sealing of the connection and avoid fluid leakage, while simplifying the installation process.
[0030] 4. The vulcanized components are connected to the welded cylinder to form a tight elastic sealing layer, which can adapt to the slight displacement caused by the thermal expansion and contraction of the pipeline and prevent sealing failure due to deformation; the axial damping ring extends to lay the second flange face, which can fill the flange connection gap and further improve the sealing performance.
[0031] 5. The first flange is a threaded flange with a neck. The neck structure of the threaded flange can increase the connection length between the first flange and the liquid-passing pipe body, making the thread engagement length longer, thereby improving the stability of the connection. In addition, the neck structure of the threaded flange wraps around the end of the liquid-passing pipe body, adding a layer of protection and support to the end of the liquid-passing pipe body, and enhancing the structural strength of the end of the liquid-passing pipe body.
[0032] 6. At the connection between the screw and the second flange, spring washers and flat washers are sequentially installed along the screw axis. The flat washers are tightly attached to the surface of the second flange, filling the small unevenness around the threaded hole, reducing the sealing gap caused by surface unevenness, and together with the elastic sealing layer of the vulcanization component, further improving the overall sealing performance of the passage section and preventing fluid leakage from the connection gap.
[0033] 7. O-rings are installed at the connection points between the welded cylinder and the vulcanizing components, as well as at the connection points between the end cap and the liquid passage pipe. This effectively prevents fluid leakage from these connections and meets the requirements for sealing and pressure bearing of the transom components. Attached Figure Description

[0041] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0042] During installation, holes are first drilled in the bulkhead, and the welding cylinder 3 is directly welded to the bulkhead. Since the welding cylinder 3 is welded to the bulkhead, a large amount of heat is generated during welding, which will cause deformation of the liquid passage pipe assembly 4, vulcanizing assembly 2, and O-ring 6 rubber, and damage the rubber properties. Therefore, the welding cylinder 3 must be separated from other parts of the elastic through-bucket component before welding can be performed separately. After welding is completed and cooled, the liquid passage pipe assembly 4, O-ring 6, vulcanizing assembly 2, and first flange 1 are installed in sequence as required.
[0043] Water, oil, or cables can flow directly inside the liquid-passing pipe body 41. The first flanges 1 at both ends of the elastic passage component are directly connected to the internal pipeline flanges of the hull. This utility model has various specifications. Large water pipes and small oil pipes can be directly connected to the elastic passage component through the first flanges 1 at both ends of the elastic passage component.
[0044] like Figures 1 to 5 As shown, this utility model provides an elastic through-chamber component, including a welded cylinder 3, a liquid-passing pipe assembly 4 passing through the welded cylinder 3, the welded cylinder 3 being located in the middle of the liquid-passing pipe assembly 4, and first flanges 1 and vulcanizing components 2 symmetrically sleeved on both sides of the liquid-passing pipe assembly 4. The liquid-passing pipe assembly 4 includes a liquid-passing pipe body 41, the two first flanges 1 being detachably connected to both ends of the liquid-passing pipe body 41, and the two vulcanizing components 2 being detachably connected to both ends of the welded cylinder 3 respectively.
[0045] The liquid passage assembly 4 also includes a second buffer ring 44, which is fixedly sleeved in the middle of the liquid passage body 41. A first protrusion 45, a first buffer ring 42, and a second protrusion 46 are symmetrically fixedly arranged on the liquid passage body 41 on both sides of the second buffer ring 44. The first buffer ring 42 is fixedly connected to the side of the first protrusion 45 near the second buffer ring 44, and an anti-collision layer 43 is fixedly arranged on the outside of the second protrusion 46.
[0046] The vulcanizing assembly 2 includes an axial damping ring 22. A second flange 23 is fixedly provided at one end of the axial damping ring 22 near the welding cylinder 3, and an end cap 21 is fixedly provided at the other end of the axial damping ring 22 away from the welding cylinder 3. The axial damping ring 22 extends and is laid on the opposite surfaces of the second flange 23 and the end cap 21.
[0047] Furthermore, the first flange 1 is a threaded flange with a neck, and the outer walls at both ends of the liquid-conducting pipe body 41 are provided with threads, and the inner wall of the threaded flange with a neck engages with the threads on the outer walls at both ends of the liquid-conducting pipe body 41.
[0048] Furthermore, the outer side of the second flange 23 is provided with a ring of threaded holes 31, and the welded cylinder 3 is also provided with threaded holes 31 at the corresponding positions of the threaded holes 31, with an included angle of 15 degrees between adjacent threaded holes 31.
[0049] Furthermore, a screw 5 is inserted into the threaded hole 31, and a spring washer 8 and a flat washer 7 are sequentially arranged along the axial direction of the screw 5 at the connection between the screw 5 and the second flange 23, with the flat washer 7 close to the second flange 23.
[0050] Furthermore, the welding cylinder 3 is provided with an O-groove 9 at the position where it connects with the vulcanizing component 2, and the end cap 21 is also provided with an O-groove 9 at the position where it connects with the liquid pipe body 41. An O-ring 6 is provided in the O-groove 9.
[0051] Furthermore, the anti-collision layer 43 is a 2 mm thick vulcanized rubber layer, and the O-ring 6, axial damping ring 22, first buffer ring 42 and second buffer ring 44 are all made of vulcanized rubber.
[0052] The axial damping ring 22 is made of vulcanized rubber and extends to the opposite surfaces of the second flange 23 and the end cap 21. It absorbs the axial vibration and displacement of the pipeline through its own elastic deformation, reducing the transmission of vibration to the cabin structure. The second buffer ring 44 is made of vulcanized rubber and is fixed in the middle of the liquid pipe body 41. It can absorb axial vibration energy and allow the pipeline to undergo small axial displacement. The axial damping ring 22 and the second buffer ring 44 work together to form a flexible compensation mechanism, which can alleviate axial load and adapt to changes in working conditions. The maximum axial displacement compensation can reach 12 mm.
[0053] The axial damping ring 22, the first buffer ring 42, and the second buffer ring 44 are all vulcanized rubber, which has elastic deformation capability and can absorb radial vibration and displacement of the pipeline and adapt to radial offset. The first protrusion 45, the first buffer ring 42, and the second protrusion 46 symmetrically arranged on the liquid pipe body 41 form a "rigid support + flexible buffer" system, which allows the pipeline to deflect slightly around the central axis. At the same time, the anti-collision layer 43 buffers external radial impact, and the maximum radial displacement compensation can reach 12 mm, and the angle deflection of ≤6° is allowed.
[0054] The first flange 1 and both ends of the liquid-conducting pipe 41, and the vulcanizing assembly 2 and both ends of the welded cylinder 3 are detachable, which facilitates later maintenance, replacement of the buffer assembly or the liquid-conducting pipe 41, and reduces maintenance costs. The end cap 21 of the vulcanizing assembly 2, the second flange 23 and the axial vibration damping ring 22 are integrally vulcanized to ensure the sealing of the connection and avoid fluid leakage, while simplifying the installation process.
[0055] The vulcanizing component 2 is connected to the welded cylinder 3 to form a tight elastic sealing layer, which can adapt to the small displacement caused by the thermal expansion and contraction of the pipeline and prevent sealing failure due to deformation; the axial damping ring 22 extends to the second flange face, which can fill the gap of the second flange connection and further improve the sealing performance.
[0056] The first flange 1 is a threaded flange with a neck. The neck structure of the threaded flange can increase the connection length between the first flange and the liquid-conducting pipe body 41, making the thread engagement length longer, thereby improving the stability of the connection. In addition, the neck structure of the threaded flange wraps around the end of the liquid-conducting pipe body 41, adding a layer of protection and support to the end of the liquid-conducting pipe body 41, and enhancing the structural strength of the end of the liquid-conducting pipe body 41.
[0057] The outer side of the second flange 23 is provided with a ring of threaded holes 31, which are connected with screws 5. This allows for a uniformly distributed fastening force between the vulcanizing component 2 and the welded cylinder 3, avoiding local stress concentration caused by single-point force. The included angle between adjacent threaded holes is 15 degrees, that is, 24 holes are evenly distributed around the circumference, ensuring that the bolt spacing is consistent. After fastening, the connection plane between the vulcanizing component 2 and the welded cylinder 3 is subjected to uniform force, improving the stability of the overall structure.
[0058] At the connection between the screw 5 and the second flange 23, spring washers 8 and flat washers 7 are sequentially arranged along the axial direction of the screw 5. The flat washers 7 are in close contact with the surface of the second flange 23, filling the small unevenness around the threaded hole 31, reducing the sealing gap caused by the uneven surface, and together with the elastic sealing layer of the vulcanization component 2, further improving the overall sealing performance of the passage part and preventing fluid leakage from the connection gap.
[0059] O-rings are installed at the connection points between the welded cylinder 3 and the vulcanizing component 2, and at the connection points between the end cap 21 and the liquid-conducting pipe 41. These measures effectively prevent fluid leakage from these connections, thus meeting the requirements for sealing and pressure bearing of the transom components.
