Description

Technical Field

[0001] This invention relates to the field of measuring instruments, and more specifically, to a Coriolis mass flow meter structure resistant to vibration interference. Background Technology

[0002] In fields such as industrial production, energy transmission, and chemical manufacturing, mass flow measurement is a key link in achieving process control, cost accounting, and safety supervision. It can provide accurate fluid quality data for production systems, ensuring the stability and efficiency of production processes. Among them, mass measurement equipment based on the Coriolis force principle is widely used in flow monitoring scenarios under various complex working conditions because it can directly measure fluid mass flow and is not affected by parameters such as fluid temperature, pressure, and viscosity. It is an important component of the modern industrial measurement system.

[0003] As industrial production scale expands and process complexity increases, the flow state of fluids in pipelines becomes increasingly complex. Turbulent flow patterns such as turbulence and swirling flow are easily generated due to factors such as pipeline layout, valve opening and closing, and equipment start-up and shutdown. These turbulent flow patterns can cause pressure fluctuations and irregular impacts and vibrations on the core measurement structure inside the measuring equipment.

[0004] The vibration interference resistance design of such quality measurement equipment in the prior art is obviously insufficient. Most equipment lacks a dedicated flow optimization structure and cannot effectively improve the turbulent state of the fluid in the pipeline. The pressure fluctuations and vibration interference caused by fluid turbulence directly affect the core measurement components, making it difficult to guarantee measurement accuracy. Summary of the Invention

[0005] The existing mass flow measurement equipment has significant shortcomings in its anti-vibration interference design. Most of these devices lack a dedicated flow optimization structure, which fails to effectively improve the turbulent state of the fluid in the pipeline. The pressure fluctuations and vibration interference caused by the fluid turbulence directly affect the core measuring components, making it difficult to guarantee measurement accuracy. The purpose of this invention is to provide a vibration-resistant Coriolis mass flow meter structure.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] A vibration-resistant Coriolis mass flow meter structure includes a flow meter body, which is mounted on a pipeline via a connecting assembly. A flow rectifying assembly is disposed within the flow meter body to disperse turbulence and swirling flow within the pipeline, guiding the fluid to form a uniform laminar flow and eliminating pressure fluctuations caused by uneven flow velocity. A protective assembly is disposed outside the flow meter body to protect the flow meter body and the pipeline connection. A support assembly is disposed on a second protective cover included in the protective assembly and is used to adjust the height of the protective assembly.

[0008] Optionally, the connecting assembly includes a mounting base fixedly installed on the flow meter body, a set of movable plates slidably installed on the mounting base, a limiting block whose position is controlled by an adjusting bolt slidably installed on the movable plates, a convex ring that mates with the limiting block fixedly installed on the pipe, a threaded groove being formed on the movable plates, and an adjusting threaded sleeve being rotatably installed on the mounting base, the adjusting threaded sleeve mates with the threaded groove.

[0009] Optionally, a sealing buffer pad is fixedly installed on the mounting base, and the sealing buffer pad is located between the pipe and the flow meter body.

[0010] Optionally, the rectifier assembly includes a rectifier tube fixedly installed on the flow meter body, with one end of the rectifier tube away from the flow meter body located inside the pipe. A plurality of rectifier plates are fixedly installed on the rectifier tube, and a connecting membrane is provided between adjacent rectifier plates. A rectifier plate is provided between the rectifier plates by means of a threaded rod. The rectifier plates are horn-shaped under the constraint of the rectifier plate, and a plurality of rectifier holes are provided on the rectifier plate.

[0011] Optionally, a mounting plate is fixedly installed inside the flow meter body, the threaded rod is threadedly connected to the mounting plate, a gear is installed on the threaded rod, and a screw is rotatably connected to the flow meter body, the screw meshing with the gear.

[0012] Optionally, the protective assembly includes a first protective cover, on which a second protective cover is fixedly mounted by fixing bolts, and the first protective cover and the second protective cover cooperate to form a protective cavity.

[0013] Optionally, the first protective cover has an observation port, and the first protective cover has a movable groove, in which an arc plate is slidably installed.

[0014] Optionally, a magnetic block is fixedly installed on the arc plate, and the magnetic block cooperates with the observation port.

[0015] Optionally, a shock-absorbing component is provided inside the first and second protective covers. The shock-absorbing component includes an installation cavity opened inside the first and second protective covers. A plurality of springs are fixedly installed inside the installation cavity, and a shock-absorbing pad is fixedly installed on the springs. The shock-absorbing pad abuts against the pipe.

[0016] Optionally, a support sleeve is fixedly installed on the second protective cover, a support rod is threadedly connected to the support sleeve, and a support base plate is fixedly installed at the bottom of the support rod.

[0017] Compared with the prior art, the technical solution provided by this invention has at least the following beneficial effects:

[0018] In the above scheme, by setting up a rectifier component, the rectifier component directly acts on the flowing fluid. Through a specific structure, it disperses the originally disordered turbulence and swirl in the pipe, breaks the irregular state of fluid flow, and guides the fluid to form a laminar flow with uniform velocity and consistent flow direction. This process can eliminate pressure fluctuations caused by uneven flow velocity from the source, reduce the irregular impact and disturbance of the fluid on the internal measuring tube of the flow meter, and improve detection accuracy.

[0019] By setting up protective components, the flow meter body and pipe connections are fully protected, isolating external dust, collisions and other interference.

[0020] By incorporating support components, the height of the protective assembly can be flexibly adjusted to ensure a suitable relative position between the protective assembly and the flow meter and pipeline, guaranteeing both protection and flow stabilization. Ultimately, this reduces vibration interference, improves measurement accuracy, and extends the equipment's lifespan. Attached Figure Description

[0043] like Figures 1 to 8 As shown, this embodiment of the invention provides a vibration-resistant Coriolis mass flow meter structure, including a flow meter body 11, which is mounted on a pipe 10 via a connecting component 20. A flow rectifying component 30 is disposed within the flow meter body 11, which is used to disperse turbulence and swirling flow within the pipe 10, guiding the fluid to form a uniform laminar flow and eliminating pressure fluctuations caused by uneven flow velocity. A protective component 40 is disposed outside the flow meter body 11, protecting the connection between the flow meter body 11 and the pipe 10. A support component 60 is disposed on a second protective cover 42 included in the protective component 40, and is used to adjust the height of the protective component 40.

[0044] like Figure 1As shown, the flow meter body 11 is assembled and fixed to the pipe 10 through the connecting component 20 to ensure installation stability and sealing effect. The internal rectifier component 30 directly acts on the flowing fluid, and through a specific structure, it disperses the originally disordered turbulence and vortex in the pipe 10, breaks the irregular state of fluid flow, and guides the fluid to form a laminar flow with uniform velocity and consistent flow direction. This process can eliminate pressure fluctuations caused by uneven flow velocity from the source, reduce the irregular impact and disturbance of the fluid on the internal measuring tube of the flow meter, and improve detection accuracy.

[0045] like Figure 6 and Figure 7 As shown, the external protective component 40 provides all-around protection for the connection between the flowmeter body 11 and the pipe 10, isolating it from external dust, collisions, and other interference. The support component 60 is installed on the second protective cover 42, and its height can be flexibly adjusted to ensure that the protective component 40 is in a suitable relative position with the flowmeter and pipe 10, guaranteeing both protection and flow stabilization. Ultimately, this reduces vibration interference, improves measurement accuracy, and extends the service life of the equipment.

[0046] like Figure 2 and Figure 3 As shown, the connecting assembly 20 includes a mounting base 21 fixedly mounted on the flow meter body 11. A set of movable plates 23 are slidably mounted on the mounting base 21. A limiting block 24, whose position is controlled by an adjusting bolt 28, is slidably mounted on the movable plate 23. A convex ring 22 that cooperates with the limiting block 24 is fixedly mounted on the pipe 10. A threaded groove 25 is provided on the movable plate 23. An adjusting threaded sleeve 26 is rotatably mounted on the mounting base 21. The adjusting threaded sleeve 26 cooperates with the threaded groove 25.

[0047] In the connecting assembly 20, the mounting base 21 is fixed on the flowmeter body 11, providing a stable mounting foundation for the movable plate 23. The movable plate 23 can slide on the mounting base 21. The position of the limiting block 24 can be precisely controlled by adjusting the bolt 28, so that the limiting block 24 and the convex ring 22 on the pipe 10 are tightly engaged, realizing the precise positioning and fixation of the flowmeter body 11 and the pipe 10. At the same time, rotating the adjusting threaded sleeve 26 on the mounting base 21 will cause it to mesh with the threaded groove 25 on the movable plate 23, driving the movable plate 23 to slide along the mounting base 21, further fine-tuning the connection position of the flowmeter and the pipe 10, ensuring good coaxiality between the two, avoiding installation stress when the pipe 10 and the flowmeter are connected, reducing vibration transmission caused by connection deviation, ensuring stable vibration of the flowmeter measuring tube, and improving measurement accuracy.

[0048] like Figure 2As shown, a sealing buffer pad 27 is fixedly installed on the mounting base 21. The sealing buffer pad 27 is located between the pipe 10 and the flow meter body 11. On the one hand, it can fill the tiny gaps at the connection surfaces of the two, enhance the sealing performance, prevent fluid leakage, and avoid pressure fluctuations and vibrations caused by leakage. On the other hand, the sealing buffer pad 27 has elastic deformation capability, which can absorb the tiny expansion and contraction and displacement of the pipe 10 caused by temperature changes and pressure fluctuations, buffer the vibration transmitted from the pipe 10 to the flow meter body 11, reduce the impact of vibration on the internal measurement structure of the flow meter, and protect the connection surface from wear, maintaining a long-term stable sealing and vibration reduction effect.

[0049] like Figure 3 and Figure 5 As shown, the rectifier assembly 30 includes a rectifier tube 31 fixedly installed on the flow meter body 11. The end of the rectifier tube 31 away from the flow meter body 11 is located inside the pipe 10. A plurality of rectifier plates 32 are fixedly installed on the rectifier tube 31. A connecting membrane 33 is provided between adjacent rectifier plates 32. A rectifier plate 38 is provided between the rectifier plates 32 by means of a threaded rod 35. The rectifier plates 32 are horn-shaped under the restriction of the rectifier plate 38. A plurality of rectifier holes 39 are provided on the rectifier plate 38.

[0050] The rectifier tube 31 of the rectifier assembly 30 is fixed on the flow meter body 11, and the end away from the flow meter body 11 extends into the pipe 10, so that the fluid is rectified before entering the flow meter. Several rectifier vanes 32 on the rectifier tube 31 are horn-shaped under the restriction of the rectifier plate 38, which can guide the fluid to gradually converge and smoothly transition. The connecting membrane 33 between adjacent rectifier vanes 32 enhances the integrity and stability of the rectifier structure. The rectifier plate 38 is fixed by the threaded rod 35, and several rectifier holes 39 on it can further disperse the turbulent vortices in the fluid, force the fluid to flow uniformly in the direction of the rectifier holes 39, and form a stable laminar flow. The multi-stage rectification design can thoroughly improve the fluid flow state, eliminate pressure fluctuations caused by uneven flow velocity, reduce irregular disturbances of the fluid to the measuring tube, allow the measuring tube to maintain stable natural vibration, and improve the accuracy of Coriolis force detection.

[0051] like Figure 3 As shown, an mounting plate 34 is fixedly installed inside the flow meter body 11, the threaded rod 35 is threadedly connected to the mounting plate 34, a gear 36 is installed on the threaded rod 35, and a screw 37 is rotatably connected to the flow meter body 11, and the screw 37 is meshed with the gear 36.

[0052] The mounting plate 34 inside the flowmeter body 11 provides a stable mounting and support point for the threaded rod 35. The threaded rod 35 is threadedly connected to the mounting plate 34. Rotating the threaded rod 35 allows for axial movement. The gear 36 on the threaded rod 35 meshes with the screw 37 rotatably connected to the flowmeter body 11. Rotating the screw 37 drives the gear 36 to rotate, thereby driving the threaded rod 35 to move axially, thus adjusting the position of the rectifier plate 38. By adjusting the position of the rectifier plate 38, the relative position of the flared opening angle of the rectifier plate 32 and the rectifier hole 39 can be changed, adapting to different flow rates and different viscosities of fluids. This ensures that turbulence can be effectively dispersed and laminar flow guided under various conditions, continuously and stably reducing vibrations caused by fluid turbulence, and guaranteeing the measurement accuracy of the flowmeter in different application scenarios.

[0053] like Figure 7 As shown, the protective component 40 includes a first protective cover 41, on which a second protective cover 42 is fixedly installed by fixing bolts 43. The first protective cover 41 and the second protective cover 42 cooperate to form a protective cavity, which completely encloses the flow meter body 11 and the connection of the pipe 10. The closed protective cavity can effectively isolate external dust, water vapor, foreign object collisions and other interference, avoid damage to the flow meter body 11 caused by external factors, and reduce the transmission of environmental vibration to the flow meter. This split structure that can be fixed by bolts is easy to install and disassemble, which not only ensures the comprehensiveness and reliability of protection, but also provides convenience for later equipment inspection and maintenance. Without affecting maintenance efficiency, it continuously provides a stable working environment for the flow meter and reduces vibration and measurement errors caused by external interference.

[0054] The first protective cover 41 has an observation port 44, and a movable groove 45 is provided inside the first protective cover 41. An arc plate 46 is slidably installed in the movable groove 45. The observation port 44 on the first protective cover 41 allows operators to observe the flow meter's operating status, readings, and the sealing condition of the connection parts without disassembling the protective cover, improving maintenance convenience. The movable groove 45 inside the first protective cover 41 provides a sliding track for the arc plate 46, which can slide flexibly within the movable groove 45. When observation is not required, the sliding arc plate 46 can close the observation port 44, preventing dust and moisture from entering the protective cavity through the observation port 44, ensuring the sealing and dustproof effect of the protective cavity. This openable and closable observation port 44 design meets daily observation needs without compromising the overall protective performance of the protective component 40, continuously maintaining a clean working environment for the flow meter, and reducing the impact of external interference on equipment operation.

[0055] A magnetic block 47 is fixedly installed on the arc plate 46. The magnetic block 47 cooperates with the observation port 44. Utilizing magnetic attraction, the arc plate 46 can be firmly fixed in the position of the observation port 44, ensuring the reliability of the seal when the observation port 44 is closed. This prevents dust and moisture from entering the protective cavity through the gap between the arc plate 46 and the observation port 44. When observation is required, a certain external force can be applied to overcome the magnetic force, and the arc plate 46 can be slid open to open the observation port 44. The operation is convenient. The attraction of the magnetic block 47 can also prevent the arc plate 46 from shifting due to equipment vibration or slight external impact, ensuring the stability of the closed state of the observation port 44. This continuously maintains the sealing and dustproof effect of the protective cavity, reduces the interference of external factors on the flow meter, and ensures the stable operation of the equipment.

[0056] like Figure 8 As shown, a shock-absorbing component 50 is provided inside the first protective cover 41 and the second protective cover 42. The shock-absorbing component 50 includes an installation cavity 51 opened in the first protective cover 41 and the second protective cover 42. A plurality of springs 53 are fixedly installed in the installation cavity 51. A shock-absorbing pad 52 is fixedly installed on the springs 53. The shock-absorbing pad 52 abuts against the main body of the pipe 10.

[0057] The mounting cavities 51 within the first protective cover 41 and the second protective cover 42 provide installation space for the vibration damping assembly 50. Several springs 53 within the mounting cavities 51 possess excellent elastic deformation capabilities, collectively supporting and fixing the vibration damping pad 52. The vibration damping pad 52 abuts against the main body of the pipe 10. When the pipe 10 vibrates, the vibration is transmitted to the vibration damping pad 52, which then transfers the vibration energy to the springs 53. The springs 53 absorb the vibration energy through elastic deformation of compression and rebound, buffering and weakening the transmission of vibration. This vibration damping structure effectively blocks the transmission of vibration from the pipe 10 to the flowmeter body 11, while simultaneously absorbing vibrations transmitted from the external environment to the protective cover. This reduces the interference of vibration on the vibration modes of the measuring tube inside the flowmeter, allowing the measuring tube to maintain stable inherent vibration, ensuring measurement accuracy, and reducing wear and tear on precision components inside the equipment.

[0058] like Figure 6As shown, a support sleeve 61 is fixedly installed on the second protective cover 42. A support rod 62 is threadedly connected to the support sleeve 61, and a support base plate 63 is fixedly installed at the bottom of the support rod 62. The support sleeve 61 on the second protective cover 42 is threadedly connected to the support rod 62. Rotating the support rod 62 can adjust its length extending out of the support sleeve 61, thereby adjusting the overall height of the protective component 40. The support base plate 63 at the bottom of the support rod 62 increases the contact area with the ground, improving the stability of the support. By adjusting the support height, the protective component 40 can maintain the optimal relative position with the flow meter and the pipe 10, ensuring that the protective component 40 can fully cover and protect the connection between the flow meter and the pipe 10, while avoiding vibration transmission caused by direct contact between the protective component 40 and the flow meter or pipe 10. The support base plate 63 can evenly transfer the weight of the protective component 40 to the ground, avoiding the weight of the protective component 40 acting on the flow meter or pipe 10, reducing additional stress and vibration interference, and ensuring the installation stability and measurement accuracy of the flow meter.

[0059] The specific workflow of the technical solution provided by this invention is as follows:

[0060] This invention achieves stable operation of a Coriolis mass flow meter with anti-vibration interference through the coordinated cooperation of the rectifier assembly 30, the connecting assembly 20, the protective assembly 40, the shock-absorbing assembly 50, and the supporting assembly 60. First, the rectifier tube 31 in the rectifier assembly 30 extends into the pipe 10, and the rectifier plate 32 guides the fluid in a trumpet shape. The rectifier hole 39 on the rectifier plate 38 further disperses the turbulence. The position of the rectifier plate 38 is adjusted by the screw 37 and the gear 36, and the opening angle of the rectifier plate 32 is adjusted to adapt to different working conditions, transforming the fluid into a uniform laminar flow, eliminating pressure fluctuations caused by uneven flow velocity, and reducing the disturbance of the fluid to the measuring tube.

[0061] The connecting component 20 cooperates with the mounting base 21, movable plate 23, limit block 24 and convex ring 22, and the position is finely adjusted by adjusting threaded sleeve 26 to ensure precise coaxial connection between the flow meter and the pipeline 10. The sealing buffer pad 27 on the mounting base 21 enhances the seal and buffers the small displacement and vibration of the pipeline 10.

[0062] The first protective cover 41 and the second protective cover 42 of the protective assembly 40 form a closed protective cavity through the fixing bolts 43, which covers the connection between the flow meter body 11 and the pipeline 10. The arc plate 46 on the first protective cover 41 cooperates with the magnetic block 47 to realize the opening and closing and sealing of the observation port 44, and isolate external dust and collision interference.

[0063] The shock-absorbing component 50 inside the protective cover absorbs vibrations from the pipe 10 and the environment through spring 53 and shock-absorbing pad 52, thereby reducing vibration transmission.

[0064] The support sleeve 61 and support rod 62 of the support assembly 60 cooperate with the support base plate 63 to adjust the height of the protective assembly 40, so that the protective assembly 40 is independently supported on the ground, avoiding the transfer of weight and stress to the flow meter. Each component works together to reduce various vibration interferences from multiple aspects such as optimizing fluid flow pattern, stabilizing installation and connection, isolating external interference, and absorbing vibration energy, ensuring that the flow meter measuring tube maintains stable natural vibration, ultimately achieving high-precision measurement and extending the service life of the equipment.

[0065] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
