Description

Technical Field

[0001] This invention relates to the field of pressure controller technology, specifically to an impact-resistant industrial pressure controller with a multi-directional vibration damping and isolation device. Background Technology

[0002] Industrial pressure controllers are core pressure monitoring and protection components in industrial fluid control systems. They are widely used in harsh environments such as hydraulic systems, mining machinery, metallurgical equipment, petrochemical pipelines, and stamping production lines. They are used to monitor the fluid pressure in pipelines in real time and output on / off control signals when the pressure reaches a set threshold to ensure system safety. In these application scenarios, equipment operation generates continuous multi-directional mechanical vibrations, and the fluid in the pipeline is prone to instantaneous high-pressure impacts such as water hammer and pressure pulses. These loads are directly transmitted to the pressure controller, causing continuous damage to the pressure-sensitive elements, transmission mechanisms, and electrical contacts. This leads to failures such as control accuracy drift, poor contact, and component fatigue fracture, severely shortening the service life and operational reliability of the equipment.

[0003] Currently, the vibration reduction dimensions of existing industrial pressure controller vibration isolation structures are limited. Conventional anti-vibration solutions mostly only place axial vibration damping pads at the bottom of the controller installation, which can only buffer vibrations in a single axis and cannot effectively isolate vibration loads in multiple directions such as lateral, circumferential, and torsional. The precision sensing and transmission components inside the controller are subjected to multi-directional alternating stress for a long time, which can easily lead to problems such as fastener loosening, transmission jamming, and control parameter deviation. They cannot meet the requirements for long-term stable operation under strong vibration conditions. Therefore, we propose an impact-resistant industrial pressure controller with a multi-directional vibration damping isolation device. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes a synergistic system comprised of vibration isolation components, damping plates, connecting components, radial floating ring components, and impact-resistant components. A multi-directional multi-directional vibration reduction system is formed by a first telescopic rod deployed in multiple directions, combined with a damping plate featuring an internal air groove. This system can simultaneously counteract lateral, longitudinal, torsional, and axial multi-dimensional vibration loads. The system relies on the energy dissipation of rod deformation and the coupled buffering effect of air damping from the air grooves to prevent external vibrations and pipeline vibrations from being transmitted to the controller. Simultaneously, the connecting components employ a ball-bearing rolling friction structure to reduce floating resistance, and work with a first return spring to achieve multi-directional displacement compensation. A carbon sealing ring and radial floating ring components form a dual dynamic sealing structure, which can compensate for gaps in real time during the radial floating of the connecting structure, ensuring a tight seal throughout. Additionally, an independent mechanical impact-resistant component is provided. When water hammer or instantaneous high-pressure pulses occur in the pipeline, the slope plate autonomously redirects the force, quickly driving the protective cover to close the monitoring end for passive protection. Combined with a venting channel to divert and depressurize, the impact load is reduced. After the impact, the component automatically resets with the help of a torsion spring, without interfering with the normal pressure detection operation of the device. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-12As shown, the present invention provides a technical solution: an impact-resistant industrial pressure controller with a multi-directional vibration damping and isolation device, including a controller 2, an isolation component 1 for isolating external vibrations is sleeved on the outside of the controller 2, a connecting component 3 for fixing is fixedly connected to the lower outer wall of the controller 2, a damping plate 5 for vibration damping is fixedly connected between the lower outer wall of the controller 2 and the lower inner outer wall of the isolation component 1, an impact-resistant component 4 for protecting the monitoring end of the controller 2 is fixedly connected to the lower outer wall of the connecting component 3, a radial floating ring component 7 for sealing when the connecting component 3 floats is sleeved on the inner wall of the connecting component 3, and an air groove 6 for providing buffering is opened on the inner wall of the damping plate 5.

[0020] Furthermore, the controller 2 is externally fitted with a vibration isolation component 1 to form an outer vibration damping isolation layer, which is used to isolate the multi-directional vibration transmitted from the external environment to the controller 2. The lower outer wall of the controller 2 is fixedly installed with a connecting component 3, which serves as the connection and installation base between the device and the pipeline under test. The lower outer wall of the controller 2 is fixedly connected with a damping plate 5 to form a bottom axial vibration damping support. The lower outer wall of the connecting component 3 is fixedly connected with an impact-resistant component 4, which is correspondingly set on the flow-facing side of the pressure monitoring end of the controller 2 to resist the instantaneous impact of the fluid. The inner wall of the connecting component 3 is fitted with a radial floating ring component 7 to fill the connection gap and achieve dynamic sealing in the floating state. The inner wall of the damping plate 5 is provided with an air groove 6. The air groove 6 is a closed cavity structure. When compressed by vibration, the internal air forms air damping, which is coupled with the damping of the damping plate 5 itself to buffer.

[0021] In the preferred embodiment of this technical solution, please refer to Figures 1-3 As shown, the vibration isolation assembly 1 includes a vibration isolation housing 11. The inner wall of the vibration isolation housing 11 is rotatably connected to a first telescopic rod 12 via a bearing seat. The bearing seat is installed on the inner wall of the vibration isolation housing 11. The outer wall of the vibration isolation housing 11 is fixedly connected to a maintenance door panel 13 via bolts. The outer wall of the vibration isolation housing 11 is fixedly connected to a fixing hole 14.

[0022] Furthermore, the vibration isolation housing 11 is a shell-like structure that covers the controller 2. Its inner wall is fixedly mounted with a rotating shaft seat through a shaft seat base. One end of the first telescopic rod 12 is rotatably connected to the inner wall of the vibration isolation housing 11 through the shaft seat. An inspection port is opened on the side wall of the vibration isolation housing 11. A maintenance door panel 13 is detachably fixed to the inspection port by bolts. The internal structure can be opened for maintenance by removing the bolts. The outer wall of the vibration isolation housing 11 extends outward to form a fixing hole 14, which is used to fix the entire device to the equipment installation position by bolt fasteners.

[0023] In the preferred embodiment of this technical solution, please refer to Figures 1-3As shown, both ends of the first telescopic rod 12 are rotatably connected to bearings. The outer wall of the end of the first telescopic rod 12 away from the vibration isolation housing 11 is rotatably connected to the controller 2 through the bearings. The first telescopic rod 12 is arranged in multiple directions on the outer wall of the controller 2 for multi-directional vibration reduction of the controller 2.

[0024] Furthermore, both ends of the first telescopic rod 12 are equipped with rotating shaft seats. The end away from the vibration isolation housing 11 is rotatably connected to the outer wall of the controller 2 through the shaft seats. Multiple first telescopic rods 12 are distributed and arranged in multiple spatial directions such as the circumference and lateral direction of the controller 2, respectively corresponding to different load directions such as the transverse, longitudinal, and oblique directions, forming a multi-directional vibration reduction support system. When vibration loads in different directions are transmitted, the first telescopic rod 12 in the corresponding direction consumes vibration energy through telescopic deformation and deflection of the rotating pair, blocking the transmission of vibration to the controller 2.

[0025] In the preferred embodiment of this technical solution, please refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the connecting assembly 3 includes a connector 31. A sealing ring 32 is fixedly connected to the outer wall of the connector 31. A floating sleeve 34 is slidably connected to the inner wall of the connector 31. Both the upper and lower outer walls of the floating sleeve 34 are provided with annular grooves 35. A ball bearing 33 is rotatably connected to the inner wall of the annular groove 35. A carbon sealing ring 36 is fitted onto the outer wall of the floating sleeve 34. A floating arc-shaped connecting plate 38 is slidably connected to the outer wall below the connector 31. A movable groove 311 is provided on the inner wall of the connection between the floating arc-shaped connecting plate 38 and the connector 31. A first return spring 39 is fixedly connected to the inner wall of the movable groove 311. Baffles 310 are fixedly connected to the outer walls at both ends of the first return spring 39.

[0026] Furthermore, the connector 31 is a hollow tubular structure, with a sealing ring 32 fixedly connected to its outer wall. A floating sleeve 34 is slidably connected to the inner wall of the connector 31. The floating sleeve 34 is coaxially arranged with the connector 31. Both the upper and lower outer walls of the floating sleeve 34 are provided with annular grooves 35. Several balls 33 are embedded and rotatably connected to the inner wall of the annular groove 35. The balls 33 are evenly arranged around the annular groove 35 to convert the sliding friction between the floating sleeve 34 and the connector 31 into rolling friction. A carbon sealing ring 36 is directly fitted onto the outer wall of the floating sleeve 34 to compensate for the gaps generated during floating and to further limit the floating range. A floating arc-shaped connecting plate 38 is slidably connected to the lower outer wall of the connector 31. The mating end faces of the floating arc-shaped connecting plate 38 and the connector 31 are respectively provided with movable grooves 311. A first return spring 39 is fixedly connected to the inner wall of the movable groove 311. Baffles 310 are fixedly connected to the outer walls at both ends of the first return spring 39.

[0027] In the preferred embodiment of this technical solution, please refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the outer wall of the baffle 310 away from the first return spring 39 is fixedly connected to the movable groove 311 opened inside the connector 31, and the other baffle 310 away from the outer wall of the first return spring 39 is fixedly connected to the inner wall of the floating arc-shaped connecting plate 38 which has the movable groove 311. The first return spring 39 is used to provide continuous thrust and compensate for the distance the connector 31 and the floating arc-shaped connecting plate 38 move.

[0028] Furthermore, two sets of baffles 310 are respectively fixed to both ends of the first return spring 39. One baffle 310 is away from the outer wall of the first return spring 39 and is fixedly connected to the inner wall of the movable groove 311 opened inside the connector 31. The other baffle 310 is away from the outer wall of the first return spring 39 and is fixedly connected to the inner wall of the movable groove 311 opened inside the floating arc-shaped connecting plate 38. The first return spring 39 is always in a pre-compressed state, providing a continuous opposing thrust to the connector 31 and the floating arc-shaped connecting plate 38. When the connector 31 and the floating arc-shaped connecting plate 38 are relatively displaced, the first return spring 39 compensates for the displacement through its own expansion and contraction deformation and provides elastic restoring force.

[0029] In the preferred embodiment of this technical solution, please refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the diameter of the ball bearing 33 in the annular groove 35 is large enough to provide a floating gap. Both ends of the sealing ring 32 are rigid, and the middle of the sealing ring 32 is made of flexible material to avoid obstructing the floating. The outer wall above the sealing ring 32 is fixedly connected to the inner wall below the vibration isolation housing 11. The outer wall of the carbon sealing ring 36 is in contact with the inner wall of the sealing ring 32.

[0030] Furthermore, the inner diameter of the annular groove 35 is larger than the outer diameter of the ball 33, leaving sufficient clearance as a floating distance to meet the radial free floating requirement of the floating sleeve 34. The upper and lower ends of the sealing ring 32 are made of hard engineering plastic to ensure structural support strength, while the middle section of the sealing ring 32 is made of flexible rubber, which can be deformed at will and will not hinder the radial floating action of the floating sleeve 34. The upper outer wall of the sealing ring 32 is sealed and fixed to the lower inner wall of the vibration isolation housing 11, achieving overall sealing of the lower end of the housing. The outer annular wall of the carbon sealing ring 36 is fully attached to the inner wall of the sealing ring 32, forming an annular sealing barrier. The upper outer wall of the sealing ring 32 is fixedly connected to the lower inner wall of the vibration isolation housing 11, forming the outer perimeter sealing structure of the lower part of the device.

[0031] In the preferred embodiment of this technical solution, please refer to Figure 1 , Figure 2 , Figure 9 , Figure 11 and Figure 12 As shown, the impact-resistant component 4 includes a protective cover 41. A connecting guide rod 42 is slidably connected to the inner wall of the protective cover 41. A third telescopic rod 43 is fixedly connected to the inner wall of the protective cover 41 near the top. A slider 44 is fixedly connected to the outer wall of the third telescopic rod 43 away from the protective cover 41. A rotating shaft 45 is fixedly connected to the outer wall below the protective cover 41. A top rod 46 is rotatably connected to the inner wall of the rotating shaft 45. A rotating shaft 45 is also rotatably connected to the inner wall of the top rod 46 away from the protective cover 41. A slope plate 47 is fixedly connected to the outer wall below the rotating shaft 45 at the end away from the protective cover 41. A fixing rod 48 is rotatably connected to the inner wall of the slope plate 47. A torsion spring 49 is sleeved and connected to the outer wall of the fixing rod 48 located inside the slope plate 47. A drainage groove 410 is opened on the inner wall of the slope plate 47 away from the top rod 46.

[0032] Furthermore, a connecting guide rod 42 is slidably connected to the inner wall of the protective cover 41 to provide axial guidance for the lifting and lowering movement of the protective cover 41. A third telescopic rod 43 is fixedly connected to the inner wall of the protective cover 41 near the top. A slider 44 is fixedly connected to the outer wall of the third telescopic rod 43 away from the protective cover 41. The third telescopic rod 43 provides auxiliary support and elastic buffer for the protective cover 41. A rotating shaft 45 is fixedly connected to the outer wall of the lower part of the protective cover 41. A top rod 46 is rotatably connected to the inner wall of the rotating shaft 45. The top rod 46 is located away from the protective cover 41. A rotating shaft 45 is rotatably connected to the inner wall at one end. A slope plate 47 is fixedly connected to the outer wall below the rotating shaft 45 on the side away from the protective cover 41. A fixing rod 48 is rotatably connected to the inner wall of the slope plate 47. The fixing rod 48 is horizontally fixedly installed on the inner wall of the pipe interface. A torsion spring 49 is sleeved and connected to the outer wall between the fixing rod 48 and the inside of the slope plate 47 to provide reset torque for the slope plate 47. A drainage groove 410 is opened on the inner wall of the slope plate 47 at the end away from the top rod 46 to divert part of the impact fluid and weaken the impact energy.

[0033] In the preferred embodiment of this technical solution, please refer to Figure 1 , Figure 2 , Figure 9 , Figure 11 and Figure 12 As shown, the protective cover 41 has a slot on its outer wall opposite to the flow of the medium. The outer wall of one end of the torsion spring 49 is fixedly connected to the fixed rod 48, and the outer wall of the other end of the torsion spring 49 is fixedly connected to the inner wall of the slope plate 47. The outer wall above the connecting guide rod 42 is fixedly connected to the outer wall below the outer wall of the connector 31 near the floating arc-shaped connecting plate 38. The outer wall of the slider 44 is slidably connected to the guide plate 411. The outer wall above the guide plate 411 is fixedly connected to the outer wall below the floating arc-shaped connecting plate 38. The top rod 4... 6 is used to transfer the upward force to the protective cover 41. The protective cover 41 is used to isolate and protect the monitoring head inside the floating arc-shaped connecting plate 38. The slope plate 47 is tilted upward at the end near the top rod 46, and the top rod 46 is tilted downward to receive the impact force brought by the medium. The slope plate 47 has a slope to lift the end near the top rod 46 upward. The fixing rod 48 is used to provide torque to the slope plate 47 that has flipped when the impact force of the medium decreases, so as to drive the slope plate 47 to reset, thereby driving the protective cover 41 to reset.

[0034] Furthermore, a connecting slot is opened on the side wall of the protective cover 41 facing away from the direction of medium flow to ensure that the medium can normally contact the monitoring probe under normal non-impact conditions without affecting pressure detection. One end of the torsion spring 49 is fixed to the outer wall of the fixed rod 48, and the other end is fixed to the inner wall of the slope plate 47. The upper end of the connecting guide rod 42 is fixedly connected to the lower outer wall of the floating arc-shaped connecting plate 38. The outer side of the slider 44 slides against the guide plate 411. The upper end of the guide plate 411 is fixedly connected to the lower end of the floating arc-shaped connecting plate 38. The slope plate 47 tilts upward at the end near the top rod 46 and tilts downward at the end away from the top rod 46. When the medium impacts and presses down on the lower end of the slope plate 47, the slope surface pushes the top rod 46 upward. The top rod 46 transmits the vertical pushing force to the protective cover 41, pushing the protective cover 41 to move upward and wrap around the monitoring head to complete the protection. When the fluid impact force decreases, the torsion spring 49 releases the torque to drive the slope plate 47 to rotate and reset, and simultaneously drive the top rod 46 and the protective cover 41 to fall back to reset.

[0035] In the preferred embodiment of this technical solution, please refer to Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the radial floating ring assembly 7 includes a floating ring 71, a second return spring 72 is snapped into the inner wall in the middle of the floating ring 71, and guide slots 74 are provided on the inner walls of the floating ring 71 on both sides of the second return spring 72. Guide protrusions 73 are slidably connected to the outer walls of the guide slots 74.

[0036] Furthermore, the floating ring 71 is a semi-circular structure arranged symmetrically. A second return spring 72 is engaged between the inner walls of the two sets of floating rings 71. The inner walls of the floating ring 71 on both sides of the second return spring 72 are provided with guide grooves 74. The outer walls of the guide grooves 74 are slidably connected with guide protrusions 73. The guide protrusions 73 are fixed on the connecting base, restricting the floating ring 71 to only translate radially and avoiding circumferential deflection.

[0037] In the preferred embodiment of this technical solution, please refer to Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the floating ring 71 is installed at the connection between the connector 31 and the floating sleeve 34 to compensate for the gap caused by the floating sleeve 34 to achieve a floating seal. The second return spring 72 is used to provide tension between the floating rings 71 to drive the moving floating rings 71 to return to their original position. The guide protrusion 73 cooperates with the guide groove 74 to guide the floating rings 71 when they return to their original position. The outer wall of the floating ring 71 fits against the inner wall of the sealing ring 32.

[0038] Furthermore, the floating ring 71 is installed at the mating connection between the connector 31 and the floating sleeve 34 to compensate for the mating gap caused by the radial floating of the floating sleeve 34, thereby achieving dynamic sealing in the floating state. The second return spring 72 provides continuous opposing tension to the two sets of floating rings 71, causing the floating rings 71 that have undergone radial displacement to automatically return to their original positions. The guide protrusion 73 cooperates with the guide groove 74 to provide guidance and constraint for the return movement of the floating rings 71. The outer wall of the floating ring 71 fits against the inner wall of the sealing ring 32 to form a complete and continuous radial sealing surface, blocking the medium leakage path.

[0039] Working principle: The entire device is fixedly installed on the equipment base through the fixing holes 14 on the outer wall of the vibration isolation housing 11 inside the vibration isolation component 1. The multi-directional vibration load generated by the external equipment is first transmitted to the vibration isolation housing 11. The inner wall of the vibration isolation housing 11 receives vibrations from different directions such as transverse, longitudinal, and torsional through the first telescopic rod 12 arranged in multiple directions by the bearing seat. The vibration energy is consumed by its own telescopic deformation and the rotation deflection of the bearing seats at both ends, blocking the transmission path of the vibration load to the internal controller 2, and realizing circumferential multi-dimensional vibration reduction and isolation.

[0040] Meanwhile, the damping plate 5 between the bottom of the controller 2 and the inner bottom of the vibration isolation housing 11 bears the axial vibration load. When the damping plate 5 is deformed by vibration, the closed air in its internal air groove 6 is compressed to form air damping, which forms a coupling buffer effect with the material damping of the damping plate 5 itself, further attenuating the axial vibration. Finally, it works with the circumferential first telescopic rod 12 to form a three-dimensional multi-directional vibration reduction system, protecting the precision sensing and transmission components inside the controller 2 from alternating vibration damage. The maintenance door panel 13 on the side wall of the vibration isolation housing 11 is a detachable structure that does not affect the normal operation of the device and is only opened during maintenance and adjustment.

[0041] The connector 31 inside the connecting component 3 is connected and fixed to the pipeline of the fluid being measured. When the pipeline vibration is transmitted to the controller 2, the floating sleeve 34 on the inner wall of the connector 31 achieves radial small-amplitude floating through the balls 33 in the upper and lower annular grooves 35, converting the sliding friction of the connection part into rolling friction, releasing radial vibration stress under low resistance, avoiding direct transmission of vibration and stress concentration caused by rigid connection. The carbon sealing ring 36 on the outer side of the floating sleeve 34 always fits against the inner wall of the sealing ring 32 to form a basic radial seal, while limiting the maximum floating amplitude of the floating sleeve 34.

[0042] The floating arc-shaped connecting plate 38 at the lower part of the connector 31 cooperates with the connector 31 through the movable groove 311, the first return spring 39 and the baffle 310, which can realize the relative displacement in the axial and deflection directions. The first return spring 39 compensates for the displacement by stretching and deforming and provides a return force, further absorbing multi-directional vibration loads.

[0043] During the floating process, the radial floating ring assembly 7, located at the interface between the connector 31 and the floating sleeve 34, works synchronously. Under the continuous tension of the second return spring 72, the two sets of floating rings 71 fill the gap generated by the radial floating of the floating sleeve 34 in real time. The sliding fit between the guide protrusion 73 and the guide groove 74 constrains the floating ring 71 to only move radially, avoiding circumferential deflection and uneven wear. This ensures that the outer wall of the floating ring 71 is always tightly attached to the inner wall of the sealing ring 32, forming a continuous and stable dynamic sealing surface. This blocks the leakage path of the medium throughout the entire floating stroke, taking into account both the floating buffer performance and the sealing reliability.

[0044] Under normal operating conditions, fluid can contact the pressure monitoring end of the controller 2 through the slot on the side of the protective cover 41 inside the impact-resistant component 4, ensuring that the pressure detection path is unobstructed and does not affect the normal measurement and control function. When water hammer effect, instantaneous high-pressure pulse or other impact loads occur in the pipeline, the high-speed fluid first impacts the lower end of the slope plate 47. The inclined slope of the slope plate 47 converts the positive impact force of the fluid into a lifting torque, causing the slope plate 47 to rotate upward around the fixed rod 48. Then, the top rod 46 is driven to move upward through the rotating shaft 45, transmitting the lifting force to the protective cover 41. The protective cover 41 is vertically lifted along the connecting guide rod 42, while the slider 44 slides synchronously along the guide plate 411. The third telescopic rod 43 provides auxiliary support and buffer limit. Finally, the protective cover 41 covers and encloses the monitoring end, isolating the direct effect of the high-pressure impact on the sensitive element. During the impact, the drainage groove 410 at the end of the slope plate 47 can divert part of the impact fluid, directly weakening the impact energy and reducing the structural load.

[0045] Once the fluid impact force dissipates, the torsion spring 49 releases its elastic potential energy, causing the slope plate 47 to rotate back around the fixed rod 48 to reset. Simultaneously, it pulls the top rod 46 and the protective cover 41 back to their initial positions. The side slot of the protective cover 41 then reconnects the pressure measurement path, and the device automatically resumes normal pressure monitoring without manual intervention.
