Description

Technical Field

[0001] The invention relates to the technical field of electric butterfly valve control, in particular to an electric butterfly valve control device. Background Art

[0002] In the field of industrial fluid control, electric butterfly valves are key actuators, and their sealing performance and flow field stability directly affect the safety and energy efficiency of production systems. However, traditional butterfly valves mostly use regular manual inspections or static sealing force designs, and cannot sense the wear status of the sealing surface in real time. When the medium pressure fluctuates or the valve seat ages, sudden leakage is prone to occur, and fault recovery depends on shutdown and maintenance, resulting in loss of production efficiency. Existing guide groove designs are mostly fixed geometric structures. Although they can improve the turbulence intensity at a specific flow rate, they cannot dynamically adapt to flow changes or differences in medium characteristics. Especially in variable operating conditions, fixed guide grooves may aggravate vortex shedding and cause high-frequency oscillations in the flow signal.

[0048] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0049] See also Figure 1-Figure 18The present invention provides a technical solution: an electric butterfly valve control device, involving an electric butterfly valve body 1, a rotating shaft 6 arranged in the electric butterfly valve body 1, and a valve plate 2 sleeved on the rotating shaft 6, characterized in that it includes: a sealing groove 7, which is opened in the electric butterfly valve body 1 and corresponds to the position of the valve plate 2; a first sealing strip 8, which is arranged in the sealing groove 7; a second sealing strip 11, which is sleeved on the valve plate 2; an airbag groove 9, which is opened on one side of the first sealing strip 8; a sealing airbag 10, which is arranged in the airbag groove 9 and is sealed with one side of the valve plate 2; a sealing adjustment component, It is arranged in the electric butterfly valve body 1 and the first sealing strip 8, and is used to inflate or evacuate the sealing airbag 10; the guide plates 3 are arranged in multiple groups and are distributed in a fan shape on the side of the valve plate 2 away from the sealing airbag 10, and one end of each guide plate 3 is rotatably arranged on the valve plate 2, and each guide plate 3 is provided with a guide groove 4, and a piezoelectric sensor 5 is arranged in the guide groove 4, and a vibration sensor 39 is arranged on the side of the first sealing strip 8 close to the guide plate 3; the guide adjustment component is arranged in the valve plate 2 and is connected to the guide plate 3, and is used to adjust the opening angle of the multiple fan-shaped guide plates 3.

[0050] The valve plate 2 is basically sealed by the first sealing strip 8 and the second sealing strip 11. During installation, the sealing airbag 10 on one side of the first sealing strip 8 is located at the input end of the liquid. At this time, the sealing airbag 10 is in sealing contact with the valve plate 2, thereby enhancing the sealing effect of the electric butterfly valve body 1. When the second sealing strip 11 and the first sealing strip 8 are worn, the sealing airbag 10 can be inflated by the sealing adjustment component to increase the contact surface between the sealing airbag 10 and the valve plate 2, thereby enhancing the sealing effect between the sealing airbag 10 and the valve plate 2, thereby ensuring the sealing performance of the electric butterfly valve body 1, preventing sudden leakage caused by medium pressure fluctuations or valve seat aging, and reducing production efficiency losses. When the valve plate 2 is in an open state, multiple groups of fan-shaped guide plates 3 and the guide grooves 4 opened on the guide plates 3 can effectively reduce flow field noise, and the opening angles of the multiple groups of fan-shaped guide plates 3 can be adjusted by the guide adjustment component, thereby preventing turbulence caused by dynamic flow changes, preventing vortex shedding, and preventing control oscillations caused by turbulent disturbances.

[0051] Specifically, Fig.11 As shown, the sealing adjustment component includes a piston groove 45, which is opened in the first sealing strip 8 and is connected to the sealing airbag 10. A piston 46 is slidably arranged in the piston groove 45, and both the piston groove 45 and the piston 46 are arc-shaped structures; it also includes a sealing drive component for pushing the piston 46 in the piston groove 45 to move closer to or away from the sealing airbag 10; a safety groove 47 is also opened in the first sealing strip 8, and a safety block 48 is slidably arranged in the safety groove 47, the safety groove 47 is connected to the sealing airbag 10, and a sixth spring 49 is connected between the safety groove 47 and the safety block 48.

[0052] The piston 46 is driven by the sealing drive member to approach or move away from the sealing airbag 10, thereby adjusting the contact surface between the sealing airbag 10 and the valve plate 2 to ensure the sealing effect of the sealing airbag 10 and the valve plate 2, and when the valve plate 2 is opened, a part of the sealing airbag 10 will be squeezed. At this time, the squeezed gas can be pressed into the safety groove 47 and compress the sixth spring 49. When the valve plate 2 is closed again, the compressed sixth spring 49 drives the safety block 48 to reset, and then resets the squeezed sealing airbag 10, ensuring the sealing effect of the sealing airbag 10 and the valve plate 2, and when the pressure in the pipeline is high, the sealing airbag 10 will be pressed closer to the valve plate 2, and the squeezed gas will also be pressed into the safety groove 47, thereby achieving the effect of safe pressure relief.

[0053] Specifically, Figure 11-Figure 12 As shown, the sealing drive component includes a sealing adjustment groove 50, which is provided in the electric butterfly valve body 1, and a connecting groove 55 is provided at the position of the first sealing strip 8 corresponding to the sealing adjustment groove 50, and the connecting groove 55 is connected to the piston groove 45. A sealing motor 51 is provided in the sealing adjustment groove 50, and a second screw rod 52 is connected to the output end of the sealing motor 51, and a second movable block 53 is screwed on the second screw rod 52. A fixing rod 54 is provided on the side of the second movable block 53 away from the sealing motor 51, and a push block 56 is connected on the side of the fixing rod 54 away from the second movable block 53, and a push block inclined surface 5601 is provided on the push block 56.

[0054] The second screw rod 52 is driven to rotate by the sealing motor 51, which can drive the second movable block 53 to slide toward the piston 46 in the sealing adjustment groove 50. The second movable block 53 drives the push block 56 to move toward the piston 46 through the fixed rod 54. At this time, the piston 46 can be pushed toward the sealing airbag 10 through the push block inclined surface 5601, thereby inflating the sealing airbag 10 and increasing the contact area between the sealing airbag 10 and the valve plate 2.

[0055] Specifically, Figure 12-14 as well as Fig.17As shown, the sealing drive member also includes a draw groove 59, which is provided in the connecting groove 55, and a draw block 60 is slidably provided in the draw groove 59, and a seventh spring 61 is connected between the draw block 60 and the draw groove 59, which is used to pull the draw block 60 into the draw groove 59, and a draw block inclined surface 6001 is provided on the side of the draw block 60 close to the piston groove 45, and an adjustment hole 67 is provided at the position of the piston groove 45 corresponding to the draw block 60; a positioning push groove 63 is provided at the bottom of the draw block 60, and a positioning block 66 is slidably provided in the positioning push groove 63, and an eighth spring 62 is connected between the positioning block 66 and the positioning push groove 63, which is used to push the positioning block 66 out of the positioning push groove 63, and a positioning inclined surface 6601 is provided on the side of the positioning block 66 close to the push block 56, and the push block 56 corresponds to the position of the pull block 60. A positioning groove 57 is provided at the position of the positioning block 66; a supporting block 58 is slidably arranged in the positioning groove 57, and a ninth spring 65 is connected between the positioning groove 57 and the supporting block 58, which is used to push the top of the supporting block 58 to be flush with the top of the pushing block 56. The elasticity of the ninth spring 65 is greater than the elasticity of the eighth spring 62. A spring block groove 69 is provided on one side of the pushing block 56, and a spring block 71 is slidably arranged in the spring block groove 69. A tenth spring 70 is connected between the spring block 71 and the spring block groove 69, which is used to push the spring block 71 out of the spring block groove 69. An ejection groove 68 is provided at the position of the connecting groove 55 corresponding to the spring block 71, and a fourth traction rope 64 is connected to one side of the spring block 71, and the other end of the fourth traction rope 64 passes through the pushing block 56 and is connected to the supporting block 58.

[0056] When it is necessary to evacuate the air in the sealing airbag 10, first move the push block 56 toward the pull block 60, and the push block 56 contacts the positioning inclined surface 6601 to press the positioning block 66 into the positioning push groove 63 until the positioning groove 57 is aligned with the positioning push groove 63. At this time, the eighth spring 62 pushes the positioning block 66 into the positioning groove 57, and then drives the sealing motor 51 to reverse, so that the sealing motor 51 drives the second movable block 53 to move away from the piston 46 through the second screw rod 52. At this time, the second movable block 53 drives the push block 56 to move away from the piston 46. Since the positioning block 66 is inserted into the positioning groove 57, the push block 56 can move with the pull block 60 when it moves, and then drives the pull block 60 to move toward the piston 46. The pull block 60 passes through the pull block inclined surface 6601. The cooperation between 001 and the adjustment hole 67 can push the piston 46 away from the sealing airbag 10, and then evacuate the sealing airbag 10. When the spring block groove 69 on the push block 56 moves to the position of the pop-up groove 68, the tenth spring 70 pushes the spring block 71 into the pop-up groove 68. At this time, the spring block 71 relaxes the fourth traction rope 64. Since the elasticity of the ninth spring 65 is greater than the elasticity of the eighth spring 62, the ninth spring 65 pushes the top of the supporting block 58 to be flush with the top of the push block 56, and then pushes the positioning block 66 into the positioning push groove 63. The seventh spring 61 pulls the pull block 60 to reset. Then, the sealing motor 51 rotates forward at this time, and the sealing airbag 10 is inflated. Repeating the above operations can complete the inflation and deflating of the sealing airbag 10.

[0057] Specifically, Figure 4 As shown, the guide adjustment component includes an adjustment chamber 14, which is opened in the valve plate 2, and a guide groove 12 is opened at the position of each guide plate 3 in the adjustment chamber 14, and a guide column 13 is arranged at the position of the guide plate 3 corresponding to the guide groove 12. An adjustment motor 15 is arranged in the adjustment chamber 14, and the output end of the adjustment motor 15 is connected to a first screw rod 16, and a first movable block 17 is screwed on the first screw rod 16. A connecting rod 18 is sleeved on each guide column 13, and the connecting rod 18 is rotatably connected to the guide column 13, and the other end of the connecting rod 18 is rotatably connected to the first movable block 17.

[0058] By driving the adjusting motor 15 to drive the first screw rod 16 to rotate, the first movable block 17 is driven to move toward the adjusting motor 15. At this time, the first movable block 17 cooperates with the connecting rod 18 to push the guide column 13 to move along the guide groove 12, thereby increasing the opening angle of the multiple groups of guide plates 3, and vice versa.

[0059] Specifically, Figure 4-Figure 5 As shown, the guide adjustment component also includes a reinforcement plate 20, which is fixed on the side of the guide column 13 away from the guide plate 3, and a through hole 23 is opened on the reinforcement plate 20, and a plurality of reinforcement fixing plates 21 are arranged in the adjustment cavity 14, and the plurality of reinforcement fixing plates 21 are grouped in pairs, and a group of reinforcement fixing plates 21 is connected with a guide rod 22, the guide rod 22 is arranged through the through hole 23, the reinforcement fixing plate 21 is slidably arranged in the reinforcement plate 20, and the guide rod 22 is arranged parallel to the corresponding guide groove 12.

[0060] By reinforcing the fixing plate 21 which is slidably arranged in the reinforcing plate 20, when the guide column 13 moves, the reinforcing plate 20 is driven to slide along the guide rod 22, thereby enhancing the stability of the guide column 13 when moving, thereby ensuring the stability of the opening angle adjustment of the guide plate 3.

[0061] Specifically, Figure 6-Figure 7As shown, multiple groups of linearly distributed reinforcing grooves 25 are provided on both sides of the through hole 23. The reinforcing grooves 25 are in a right-angled trapezoidal structure, and the trapezoidal inclined surface is arranged close to the first movable block 17. Multiple groups of staggered first abutting grooves 26 are provided on both sides of the guide rod 22. The spacing between the two staggered first abutting grooves 26 is half of the spacing between the two adjacent reinforcing grooves 25. The spacing between the two groups of unidirectional and adjacent first abutting grooves 26 is less than the total length of the multiple groups of linearly distributed reinforcing grooves 25. A reinforcing block 24 is slidably arranged in each first abutting groove 26. A first spring 27 is connected between the reinforcing block 24 and the first abutting groove 26 for pushing the reinforcing block 24 out of the first abutting groove 26. A cavity 29 is provided in the reinforcing fixing plate 21. A slider 33 is slidably provided in the cavity 29. A second spring 31 is connected between the slider 33 and the cavity 29 for resetting the slider 33. A first traction rope 28 is connected to one side of the slider 33. A plurality of branch ropes 1 are provided at the other end of the first traction rope 28. Each branch rope 1 passes through the guide rod 22 and is connected to each corresponding first abutting groove 26.

[0062] When the first movable block 17 moves toward the adjusting motor 15, the first movable block 17 drives the guide column 13 to move and drives the reinforcement plate 20 to slide along the guide rod 22. At this time, the trapezoidal inclined surface of the reinforcement groove 25 is away from the reinforcement block 24. Then, when the first abutting groove 26 is aligned with the reinforcement groove 25, the first spring 27 pushes the reinforcement block 24 to enter the reinforcement groove 25, thereby limiting the reinforcement plate 20 and preventing the reinforcement plate 20 from moving in the opposite direction, thereby ensuring the opening angle of the guide plate 3, and strengthening the support for the guide column 13 and the support stability of the guide plate 3. The staggered first abutting grooves 26 can enable the reinforcement plate 20 to move half of the distance between two adjacent reinforcement grooves 25. The reinforcement plate 20 can be re-limited to reduce the limiting distance. The reinforcement block 24 can be pressed into the first abutting groove 26 through the trapezoidal inclined surface of the reinforcement groove 25 without affecting the movement of the reinforcement plate 20.

[0063] Specifically, Figure 6-Figure 9As shown, a second abutting groove 35 is provided on one side of the cavity 29, a card block 30 is slidably provided in the second abutting groove 35, a card block 30 is provided on the card block 30, a third spring 36 is connected between the card block 30 and the second abutting groove 35, and is used to push the card block 30 to extend out of the second abutting groove 35, and a card slot 34 is provided on the side of the slider 33 close to the card block 30; a first extrusion groove 40 is provided in the adjusting cavity 14, a first extrusion block 19 is slidably provided in the first extrusion groove 40, an extrusion inclined surface 1901 is provided on the first extrusion block 19, and a fourth spring 41 is provided between the first extrusion block 19 and the first extrusion groove 40, and is used to push the first extrusion block 19 to extend out of the first Extrusion groove 40, one side of the first extrusion block 19 is connected to the second traction rope 32, and the other end of the second traction rope 32 is provided with multiple branch ropes 2, each branch rope 2 passes through the valve plate 2 and is connected to the corresponding slider 33; a second extrusion groove 42 is opened in the regulating chamber 14, and a second extrusion block 44 is slidably arranged in the second extrusion groove 42, and a fifth spring 43 is arranged between the second extrusion block 44 and the second extrusion groove 42, which is used to push the second extrusion block 44 to extend out of the second extrusion groove 42, one side of the second extrusion block 44 is connected to the third traction rope 38, and the other end of the third traction rope 38 is provided with multiple branch ropes 3, each branch rope 3 passes through the valve plate 2 and is connected to the corresponding clamping block 30.

[0064] When the opening angle of the guide plate 3 needs to be reduced, the first screw rod 16 is driven to rotate by the adjusting motor 15, and then the first movable block 17 is driven to move toward the first extrusion block 19. At this time, the first movable block 17 presses the first extrusion block 19 into the first extrusion groove 40 through the extrusion inclined surface 1901, and the first extrusion block 19 drives the second traction rope 32 to be tightened, and then the slider 33 is pulled toward the second spring 31 through the second traction rope 32. The slider 33 presses the block 30 into the second abutting groove 35 through the positioning inclined surface 3001 until the slot 34 is aligned with the second abutting groove 35. The third spring 36 pushes the block 30 into the slot 34 and then limits the slider 33. At this time, the slider 33 pulls the first traction rope 28 to drive multiple reinforcement blocks 24 to be retracted into the first abutting groove 26, and then When the adjusting motor 15 is reversed, the first movable block 17 is driven to move away from the first extrusion block 19. At this time, the first movable block 17 cooperates with the connecting rod 18 to push the guide column 13 to move along the guide groove 12, thereby reducing the opening angle of the multiple groups of guide plates 3. When the first movable block 17 contacts the second extrusion block 44 and presses the second extrusion block 44 into the second extrusion groove 42, the second extrusion block 44 drives the third traction rope 38 to tighten, thereby pulling the card block 30 into the second supporting groove 35. At this time, the limit on the slider 33 is cancelled, and the cavity 29 drives the slider 33 to reset and relax the first traction rope 28. At this time, the first spring 27 pushes the reinforcement block 24 to extend out of the first supporting groove 26 or cooperates with the reinforcement groove 25 to limit the reinforcement plate 20. Repeat the above operation to adjust the opening angle of the guide plate 3 at any time.

[0065] The specific solution is as follows: when installing, the sealing airbag 10 on one side of the first sealing strip 8 is located at the input end of the liquid. After the installation is completed, the electronic devices such as the sensor are initialized, and then the preset parameters are imported. When the device is working, the pressure fluctuation on one side of the valve plate 2 can be detected by the piezoelectric sensor 5. When the pressure fluctuation exceeds the preset value, the sealing performance decreases. At this time, it is necessary to drive the sealing motor 51, and then adjust the sealing effect of the valve plate 2 through the sealing adjustment component. After the adjustment is completed, it is detected whether the current exceeds the limit. If it exceeds the limit, the machine will stop and report an error. If it does not exceed the limit, the sensor data will be read again until the pressure value detected by the piezoelectric sensor 5 is within the preset pressure value, and then the vibration sensor 39 and the piezoelectric sensor 5 are adjusted. The value is analyzed to see if there is turbulence or vortex shedding. If not, the sensor data is read repeatedly. If yes, the position of the guide plate 3 and the guide groove 4 needs to be adjusted, and the adjustment motor 15 is driven to drive the guide adjustment component to adjust the position of the guide plate 3 and the guide groove 4. After adjustment, it is detected whether the current exceeds the limit. If it exceeds the limit, the machine is shut down and an error is reported. If it does not exceed the limit, the sensor data is read again. By repeating the above steps, the sealing airbag 10 of the device can be adjusted in real time to ensure the sealing of the device. The position of the guide plate 3 and the guide groove 4 can also be adjusted in real time to prevent turbulence or vortex shedding, and the oscillation can be effectively reduced, further reducing the noise of the device when it is used again.

[0066] When the sealing performance needs to be adjusted, the sealing motor 51 drives the second screw 52 to rotate, thereby driving the second movable block 53 to slide toward the piston 46 in the sealing adjustment groove 50. The second movable block 53 drives the push block 56 to move toward the piston 46 through the fixed rod 54. At this time, the push block inclined surface 5601 can push the piston 46 to move toward the sealing airbag 10, thereby inflating the sealing airbag 10 and increasing the contact surface between the sealing airbag 10 and the valve plate 2.

[0067] When it is necessary to evacuate the air in the sealed airbag 10, first move the push block 56 toward the pull block 60, and the push block 56 contacts the positioning inclined surface 6601 to press the positioning block 66 into the positioning push groove 63 until the positioning groove 57 is aligned with the positioning push groove 63. At this time, the eighth spring 62 pushes the positioning block 66 into the positioning groove 57, and then drives the sealing motor 51 to reverse, so that the sealing motor 51 drives the second movable block 53 to move away from the piston 46 through the second screw rod 52. At this time, the second movable block 53 drives the push block 56 to move away from the piston 46. Since the positioning block 66 is inserted into the positioning groove 57, the push block 56 can drive the pull block 60 to move together when it moves, and then drive the pull block 60 to move toward the piston 46. The pull block 60 passes through the pull block inclined surface 6601. The cooperation between 001 and the adjustment hole 67 can push the piston 46 away from the sealing airbag 10, and then evacuate the sealing airbag 10. When the spring block groove 69 on the push block 56 moves to the position of the pop-up groove 68, the tenth spring 70 pushes the spring block 71 into the pop-up groove 68. At this time, the spring block 71 relaxes the fourth traction rope 64. Since the elasticity of the ninth spring 65 is greater than the elasticity of the eighth spring 62, the ninth spring 65 pushes the top of the supporting block 58 to be flush with the top of the push block 56, and then pushes the positioning block 66 into the positioning push groove 63. The seventh spring 61 pulls the pull block 60 to reset. Then, the sealing motor 51 rotates forward at this time, and the sealing airbag 10 is inflated. Repeating the above operations can complete the inflation and deflating of the sealing airbag 10.

[0068] When the position of the guide plate 3 needs to be adjusted, the first movable block 17 is driven to move toward the adjustment motor 15. At this time, the first movable block 17 cooperates with the connecting rod 18 to push the guide column 13 to move along the guide groove 12, thereby increasing the opening angle of multiple groups of guide plates 3. When the first movable block 17 moves toward the adjustment motor 15, the first movable block 17 drives the guide column 13 to move and drives the reinforcement plate 20 to slide along the guide rod 22. At this time, the trapezoidal slope of the reinforcement groove 25 is away from the reinforcement block 24. Then, when the first abutting groove 26 is aligned with the reinforcement groove 25, the first spring 27 The reinforcing block 24 is pushed into the reinforcing groove 25, thereby limiting the reinforcing plate 20, preventing the reinforcing plate 20 from moving in the opposite direction, thereby ensuring the opening angle of the guide plate 3, and strengthening the support of the guide column 13 and the stability of the support of the guide plate 3. The staggered first abutting grooves 26 can make the reinforcing plate 20 move half of the distance between two adjacent reinforcing grooves 25, and then the reinforcing plate 20 can be re-limited, reducing the limiting distance. The reinforcing block 24 can be pressed into the first abutting groove 26 through the trapezoidal inclined surface of the reinforcing groove 25, without affecting the movement of the reinforcing plate 20.

[0069] When the opening angle of the guide plate 3 needs to be reduced, the first screw rod 16 is driven to rotate by the adjusting motor 15, and then the first movable block 17 is driven to move toward the first extrusion block 19. At this time, the first movable block 17 presses the first extrusion block 19 into the first extrusion groove 40 through the extrusion inclined surface 1901, and the first extrusion block 19 drives the second traction rope 32 to be tightened, and then the slider 33 is pulled toward the second spring 31 through the second traction rope 32. The slider 33 presses the block 30 into the second abutting groove 35 through the positioning inclined surface 3001 until the slot 34 is aligned with the second abutting groove 35. The third spring 36 pushes the block 30 into the slot 34 and then limits the slider 33. At this time, the slider 33 pulls the first traction rope 28 to drive multiple reinforcement blocks 24 to be retracted into the first abutting groove 26, and then When the adjusting motor 15 is reversed, the first movable block 17 is driven to move away from the first extrusion block 19. At this time, the first movable block 17 cooperates with the connecting rod 18 to push the guide column 13 to move along the guide groove 12, thereby reducing the opening angle of the multiple groups of guide plates 3. When the first movable block 17 contacts the second extrusion block 44 and presses the second extrusion block 44 into the second extrusion groove 42, the second extrusion block 44 drives the third traction rope 38 to tighten, thereby pulling the card block 30 into the second supporting groove 35. At this time, the limit on the slider 33 is cancelled, and the cavity 29 drives the slider 33 to reset and relax the first traction rope 28. At this time, the first spring 27 pushes the reinforcement block 24 to extend out of the first supporting groove 26 or cooperates with the reinforcement groove 25 to limit the reinforcement plate 20. Repeat the above operation to adjust the opening angle of the guide plate 3 at any time.
