Description

Technical Field

[0001] This utility model relates to the field of regulating valve technology, and in particular to a vibration-resistant regulating valve support device. Background Technology

[0002] In industrial production and various equipment operation scenarios, regulating valves, as core control components, bear the important responsibility of accurately regulating key process parameters such as temperature, pressure, and flow. Their operational stability directly determines the overall working efficiency and production safety of the system.

[0003] Currently, the installation structure of control valves still has significant defects in practical applications, making it difficult to meet the requirements of precise installation and stable operation in industrial settings. On the one hand, pipeline interfaces in industrial settings are easily affected by construction errors, settlement after long-term equipment operation, and thermal expansion and contraction of pipelines caused by changes in ambient temperature. This often leads to height deviations between the pipeline interface and the control valve flange, making installation difficult. If installation is forced, it can easily cause deformation of the flange structure and damage to the gasket, resulting in leakage of the medium inside the pipeline. This not only affects the continuity of production but may also cause safety accidents.

[0004] On the other hand, large equipment such as compressors and pumps in industrial sites generate continuous vibrations during operation. The control valve is affected by long-term vibrations, which can not only cause the connection between the control valve and the pipeline to become loose, affecting the connection sealing, but also cause wear and poor contact of the precision components inside the control valve. This can significantly reduce the control accuracy and service life of the control valve, and increase equipment maintenance costs and downtime risks.

[0005] Therefore, there is an urgent need to propose a vibration-resistant regulating valve support device to solve the above problems. Utility Model Content

[0011] In some alternative embodiments, the adjusting assembly further includes a first locking nut and a second locking nut, both of which are threaded into the threaded rod and configured to lock onto the upper and lower sides of the movable seat, respectively.

[0012] In some optional embodiments, a guide assembly is further provided between the base and the movable seat. The guide assembly includes a guide sleeve and a guide rod that are slidably engaged, one of which is mounted on the base and the other is mounted on the movable seat.

[0013] In some optional embodiments, the inner sidewall of the vibration-damping sleeve is provided with a limiting groove extending along its axial direction, the inner bottom wall of the limiting groove is higher than the inner bottom wall of the vibration-damping sleeve, the connecting rod is circumferentially connected with a limiting block, the limiting block is movably disposed in the limiting groove, and can abut against the inner top wall or inner bottom wall of the limiting groove to limit the axial travel of the connecting rod.

[0014] In some alternative embodiments, the damper is a viscous damper.

[0015] In some alternative embodiments, the elastic element is fitted around the damper circumferentially.

[0016] In some optional embodiments, the base is provided with a circumferentially protruding fixing block, and the fixing block is provided with a fixing hole.

[0018] The beneficial effects of this utility model are:

[0019] This utility model provides a vibration-resistant regulating valve support device, including a base, a movable seat, a mounting seat, an adjusting component, and a vibration-damping component. The base, movable seat, and mounting seat are arranged sequentially from top to bottom. The mounting seat is used to install the regulating valve. The adjusting component is disposed between the base and the movable seat, with one end rotatably connected to the base and the other end threadedly engaged with the movable seat. The vibration-damping component is disposed between the movable seat and the mounting seat, and includes an vibration-damping sleeve, a connecting rod, a damper, and an elastic element. The vibration-damping sleeve is installed on the movable seat, the damper is installed inside the vibration-damping sleeve, the connecting rod is installed on the mounting seat and slidably engaged with the vibration-damping sleeve, the lower end of the connecting rod is fixedly connected to the movable end of the damper, the lower end of the elastic element is connected to the inner bottom wall of the vibration-damping sleeve, and the upper end of the elastic element is connected to the lower end of the connecting rod.

[0020] When the system vibrates, the mounting base drives the connecting rod to slide up and down inside the vibration-damping sleeve, causing tension or compression on the elastic element. The elastic element can absorb vibration energy through elastic deformation, achieving primary buffering. The damper further absorbs vibration energy, thereby suppressing the rebound oscillation of the elastic element.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0030] In this invention, the terms "comprising," "including," "having," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0031] In this invention, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, in this invention, the character " / " generally indicates that the preceding and following related objects have an "and / or" relationship.

[0032] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," "fixed," "combined," "coupled," and "installed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can be a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For example, a direct connection refers to two parts or components being connected together without an intermediate component, while an indirect connection refers to two parts or components each being connected to at least one intermediate component, with the connection achieved through the intermediate component. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Furthermore, "connected" and "coupled" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0033] In this invention, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the value and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0034] In this invention, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can be performed by one part, one component, or a combination of multiple parts.

[0035] In this utility model, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationships shown in the accompanying drawings.

Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0036] like Figures 1-4 As shown, this embodiment provides a vibration-resistant regulating valve support device, including a base 1, a movable seat 2, a mounting seat 3, an adjusting component 4, and a vibration-resistant component 5. The base 1, movable seat 2, and mounting seat 3 are arranged sequentially from top to bottom. The mounting seat 3 is used to install the regulating valve 100. The adjusting component 4 is disposed between the base 1 and the movable seat 2, and one end of the adjusting component 4 is rotatably connected to the base 1, while the other end is threadedly engaged with the movable seat 2. The vibration-resistant component 5 is disposed between the movable seat 2 and the mounting seat 3. The vibration-resistant component 5 includes a vibration-resistant sleeve 51, a connecting rod 52, a damper 53, and an elastic element 54. The vibration-resistant sleeve 51 is installed on the movable seat 2, the damper 53 is installed inside the vibration-resistant sleeve 51, the connecting rod 52 is installed on the mounting seat 3, and is slidably engaged with the vibration-resistant sleeve 51. The lower end of the connecting rod 52 is fixedly connected to the movable end of the damper 53. The lower end of the elastic element 54 is connected to the inner bottom wall of the vibration-resistant sleeve 51, and the upper end of the elastic element 54 is connected to the lower end of the connecting rod 52.

[0037] By rotating the adjustment component 4, the horizontal height of the movable seat 2 can be adjusted, thereby adjusting the height of the mounting seat 3 until the flange 110 of the regulating valve 100 is coaxially aligned with the pipe interface. This achieves flexible adjustment of the installation height of the regulating valve 100, which can adapt to the height deviation of the pipe interface in different installation scenarios, thereby ensuring the sealing and safety of the regulating valve 100 and the pipe, and avoiding sealing failure or stress concentration problems caused by misalignment.

[0038] When the system vibrates, the mounting base 3 drives the connecting rod 52 to slide up and down inside the anti-vibration sleeve 51, causing tension or compression on the elastic element 54. The elastic element 54 can absorb vibration energy through elastic deformation, achieving primary buffering. The damper 53 further absorbs vibration energy, thereby suppressing the rebound oscillation of the elastic element 54. The elastic element 54 and the damper 53 work together to rapidly reduce and stabilize the vibration amplitude of the regulating valve 100, reducing the risk of bolt loosening due to vibration of the flange 110 on the regulating valve 100, ensuring the connection stability between the regulating valve 100 and the pipeline, protecting the internal components of the regulating valve 100, preventing precision components from being damaged by vibration, thereby ensuring the control accuracy of the regulating valve 100, extending its service life, and reducing equipment maintenance costs and downtime risks.

[0039] like Figure 3 As shown, in some optional embodiments, the adjusting component 4 includes a threaded rod 41, the lower end of which is rotatably connected to the base 1. The movable seat 2 has a threaded hole that is threadedly engaged with the threaded rod 41. The height of the movable seat 2 can be adjusted by rotating the threaded rod 41.

[0040] In some optional embodiments, a bearing 42 is embedded in the base 1, and the threaded rod 41 is rotatably engaged with the base 1 through the bearing 42. On the one hand, the bearing 42 can reduce the frictional resistance and wear between the threaded rod 41 and the bearing 42, avoiding component failure due to friction; on the other hand, the bearing 42 can provide stable radial constraint for the threaded rod 41, ensuring that the threaded rod 41 always rotates smoothly around a preset axis, which is beneficial to improving the motion stability of the threaded rod 41 and ensuring adjustment accuracy; in addition, the reduction of frictional resistance can reduce the external force required to drive the threaded rod 41 to rotate, thereby reducing operating resistance, optimizing the user experience, and improving the convenience of adjusting the installation height of the regulating valve 100.

[0041] In this embodiment, the inner ring of the bearing 42 is equipped with a rotating rod 45, and a rotating block 46 is fixedly connected to the top of the rotating rod 45. The lower end of the threaded rod 41 is fixedly connected to the rotating block 46. The rotating block 46 and the rotating rod 45 are connected to the bearing 42, which helps to improve the assembly convenience of the adjustment component 4 and facilitates the processing of the threaded rod 41.

[0042] Of course, in other embodiments, the lower end of the threaded rod 41 can also be directly assembled to the inner ring of the bearing 42, which is not limited here.

[0043] In some optional embodiments, the adjusting assembly 4 further includes a first locking nut 43 and a second locking nut 44, both of which are threaded into the threaded rod 41 and are configured to lock onto the upper and lower sides of the movable seat 2, respectively. After the movable seat 2 has been adjusted to a horizontal height, the first locking nut 43 and the second locking nut 44 are tightened, causing them to abut against the upper and lower sides of the movable seat 2, thereby locking the threaded rod 41 to the movable seat 2 and preventing the threaded rod 41 from vibrating and loosening, which could cause a change in the height of the movable seat 2.

[0044] In some alternative embodiments, such as Figures 1-4 As shown, a guide assembly 6 is also provided between the base 1 and the movable seat 2. The guide assembly 6 includes a guide sleeve 61 and a guide rod 62 that are slidably fitted. One of the two is installed on the base 1 and the other is installed on the movable seat 2. It provides precise guidance for the lifting and lowering movement of the movable seat 2, ensures that the movable seat 2 moves smoothly in the vertical direction, prevents the movable seat 2 from tilting, and improves the smoothness of movement.

[0045] To improve the force balance of the movable seat 2, this embodiment includes at least two adjustment components 4. The at least two adjustment components 4 are evenly spaced between the base 1 and the movable seat 2, which can provide stable support for the movable seat 2, prevent the movable seat 2 from tilting under force, and thus ensure the installation accuracy of the regulating valve 100.

[0046] In other embodiments, the number of adjustment components 4 includes, but is not limited to, one, two, three, or six, and is not limited herein.

[0047] Similarly, this embodiment includes at least two guide components 6, which are evenly spaced between the base 1 and the movable seat 2 and spaced apart from the adjustment component 4, so as to provide stable support and guidance for the movable seat 2 and further ensure that the movable seat 2 is subjected to balanced force.

[0048] In other embodiments, the number of guide components 6 includes, but is not limited to, one, two, three, or six, and is not limited herein.

[0049] like Figure 4As shown, in some optional embodiments, the inner sidewall of the vibration-damping sleeve 51 is provided with a limiting groove 511 extending axially therein. The inner bottom wall of the limiting groove 511 is higher than the inner bottom wall of the vibration-damping sleeve 51. The connecting rod 52 is circumferentially connected to a limiting block 521. The limiting block 521 is movably disposed within the limiting groove 511 and can abut against the inner top wall or inner bottom wall of the limiting groove 511 to limit the axial travel of the connecting rod 52. The inner bottom wall of the limiting groove 511 is higher than the inner bottom wall of the vibration-damping sleeve 51, which can limit the maximum downward travel of the connecting rod 52 and prevent the elastic element 54 from being excessively compressed under extreme vibration conditions, leading to plastic deformation failure. The inner top wall of the limiting groove 511 can limit the maximum upward travel of the limiting block 521, which on the one hand prevents the connecting rod 52 from detaching from the vibration-damping sleeve 51, and on the other hand prevents the elastic element 54 from being excessively stretched under extreme vibration conditions, leading to plastic deformation failure. This is beneficial to ensuring the operational reliability and safety of the vibration-damping assembly 5.

[0050] In this embodiment, the damper 53 is a viscous damper, which is filled with a viscous medium. When the connecting rod 52 drives the piston of the damper 53 to move, the viscous medium generates a damping force through the small holes or gaps, which hinders the movement of the piston. The damping force is proportional to the vibration speed. The greater the vibration amplitude, the stronger the damping force, which can quickly attenuate the vibration energy. The elastic element 54 first buffers the vibration impact through elastic deformation, and the damper 53 then converts the remaining vibration energy into heat energy through viscous friction, thereby suppressing the rebound oscillation of the elastic element 54.

[0051] In other alternative embodiments, the damper 53 may include, but is not limited to, a friction damper, a metal damper, or a magnetorheological damper, all of which can absorb the vibration energy of the connecting rod 52, and is not limited here.

[0052] In some optional embodiments, the elastic element 54 is sleeved around the damper 53, providing a uniform and stable elastic force to the connecting rod 52, ensuring balanced force distribution on the connecting rod 52, avoiding localized stress concentration, and improving the structural reliability of the vibration-damping assembly 5. Furthermore, the damper 53 guides and limits the compression of the elastic element 54, preventing it from bending under pressure and affecting the buffering effect, thus further improving the reliability of the vibration-damping assembly 5.

[0053] In this embodiment, the elastic element 54 is a spring, which has a simple structure, is easy to obtain, and has a low cost. Optionally, the elastic element 54 may include, but is not limited to, rubber tubing or air springs, and is not limited here.

[0054] To improve vibration resistance, such as Figure 1 and Figure 2As shown, this embodiment includes four vibration-damping components 5. Each corner of the movable seat 2 is equipped with a vibration-damping component 5. The weight of the regulating valve 100 and the external vibration load on the mounting seat 3 can be evenly distributed to each vibration-damping component 5, avoiding local component overload or tilting of the mounting seat 3 due to uneven distribution of support points, thereby ensuring the stability and reliability of the support state. At the same time, this symmetrical and comprehensive arrangement allows each vibration-damping component 5 to play a vibration-damping role simultaneously, jointly absorbing and offsetting external vibration energy, effectively avoiding local concentration or transmission imbalance of vibration inside the structure, and fully covering the vibration-affected area of ​​the mounting seat 3, maximizing the synergistic effect of each vibration-damping component 5, and achieving the maximum vibration-damping effect.

[0055] In other embodiments, the number of vibration-damping components 5 includes, but is not limited to, one, two, three, or six, and is not limited herein.

[0056] In some alternative embodiments, such as Figure 1 As shown, the base 1 has a circumferentially protruding fixing block 7, and the fixing block 7 has a fixing hole 71. The fixing hole 71 provides a standardized installation interface for the installation of the base 1, which is compatible with various fixing methods such as expansion bolts and welding nuts, and can be quickly adapted to different foundation materials, which helps to improve installation efficiency and construction convenience.

[0057] Furthermore, the fixing hole 71 is a countersunk hole, which allows the head of the connector (such as a screw or bolt) to be embedded in the hole, preventing the head of the connector from protruding from the mounting surface. This ensures the flatness of the mounting surface and prevents the protruding head from scratching surrounding parts or causing safety hazards to operators. At the same time, the countersunk hole can form a radial constraint on the head of the connector, preventing the connector from shifting or loosening under stress or vibration, and improving the stability of the base 1 installation.

[0058] It should be noted that the regulating valve 100 has a diaphragm chamber 120 at its top. This is for ease of installation of the regulating valve 100, such as... Figure 1 and Figure 2 As shown, the mounting base 3 has a mounting hole 31, and the diaphragm chamber 120 is installed in the mounting hole 31. The mounting hole 31 provides precise installation positioning for the regulating valve 100.

[0059] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
