Description

Technical Field

[0001] The present invention relates to the technical field of butterfly valve processing, and specifically to a processing device for a two-way sealed butterfly valve. Background Art

[0002] The two-way sealed butterfly valve belongs to a type of butterfly valve. Its valve seat is specially designed to achieve reliable sealing in both forward and reverse directions, ensuring that the medium does not leak from both sides of the valve, so as to be able to control the water flow in both directions, ensure the stability of the water pressure in the pipe network, and prevent damage to the equipment caused by water backflow.

[0003] With the advancement of the global industrialization process, the petrochemical, electric power, metallurgy, and water supply and drainage industries have developed rapidly. These industries widely use two-way sealed butterfly valves to regulate and control the transportation of various fluids. The sealing performance of the two-way sealed butterfly valve is affected by the accuracy of the valve body. Due to the poor accuracy of the traditional grinding method, it can no longer meet the needs of users. At this time, a processing device for a two-way sealed butterfly valve is required.

[0004] At present, the processing devices for two-way sealed butterfly valves on the market mainly consist of a workbench, fixed clamps, a driver, and a grinding head. When in use, the valve body of the two-way sealed butterfly valve is placed on the workbench and fixed with the fixed clamps, and the driver can drive the grinding head to grind the valve body. However, when this device is actually used, when grinding different parts of the butterfly valve body, it is necessary to manually move the grinding head, which not only consumes a lot of time but also easily causes operation errors due to human fatigue. To solve the above problems, the prior art often adopts the method of adding a movable grinding head to improve the grinding accuracy. However, the grinding disc will rub against the valve body during grinding, causing the valve body to deflect and reducing the grinding accuracy. The prior art adds a limiting mechanism to the fixing device to reduce the deflection of the valve body. However, when this device is actually used, due to the different inner diameters of the valve bodies of different specifications and models of butterfly valves, this device is not convenient for grinding butterfly valves of different models and specifications, reducing the practicability of this device and not meeting the needs of users.

[0022] Referring to Figure 2 , Figure 3 and Figure 4 , an embodiment of the present invention provides a processing equipment for a bi-directional seal butterfly valve, including a base 1. The middle part of the top end of the base 1 is fixedly connected with a U-shaped frame 5. The top of the U-shaped frame 5 is rotatably connected with a support disc 6. A plurality of mounting blocks 7 are equidistantly arranged on the upper side of the support disc 6. The support disc 6 drives the mounting blocks 7 to rotate.

The disassembly mechanism 4 is used to facilitate the disassembly and replacement of the grinding piece 8; The adjusting mechanism 2 includes a hollow column 201. The hollow column 201 is fixedly connected to the top of the support disk 6. A bidirectional threaded rod 202 is rotatably connected to the inner side of the hollow column 201. The upper and lower sides of the outer wall of the bidirectional threaded rod 202 are both threadedly connected with movable blocks 203. When the bidirectional threaded rod 202 rotates, the movable blocks 203 will rotate accordingly. A plurality of first support seats 204 are equidistantly and fixedly connected to the outer sides of the two movable blocks 203. Connecting rods 205 are rotatably connected to the inner sides of the plurality of first support seats 204. Second support seats 206 are fixedly connected to the upper and lower ends of the other sides of the plurality of mounting blocks 7. When the first support seats 204 move, the second support seats 206 can be pulled to move through the connecting rods 205. The plurality of second support seats 206 are respectively rotatably connected to the corresponding connecting rods 205. A driving component is arranged inside the U-shaped frame 5. The driving component includes a motor 207. The motor 207 is fixedly connected to the rear side of the U-shaped frame 5. The output end of the motor 207 penetrates through the U-shaped frame 5 and is fixedly connected to a driving bevel gear 208. The motor 207 will drive the driving bevel gear 208 to rotate. A transmission rod 209 is rotatably connected to the inner top of the U-shaped frame 5. A driven bevel gear 210 is fixedly connected to the bottom end of the transmission rod 209. The driven bevel gear 210 is meshed and connected with the driving bevel gear 208. When the driving bevel gear 208 rotates, the driven bevel gear 210 will drive the transmission rod 209 to rotate. The top end of the transmission rod 209 penetrates through the U-shaped frame 5 and is fixedly connected to the support disk 6. The transmission rod 209 will drive the support disk 6 to rotate; Specifically, when using this device, by rotating the bidirectional threaded rod 202, the movement of the movable blocks 203 is driven. The movement of the movable blocks 203 will further drive the movement of the first support seats 204, and the second support seats 206 are pulled to move through the connecting rods 205. The mounting blocks 7 will drive the grinding discs 8 to move accordingly, so as to polish butterfly valves of different sizes and models. At the same time, the motor 207 will drive the driving bevel gear 208 to rotate. Since the driven bevel gear 210 is meshed with the driving bevel gear 208, the driven bevel gear 210 can transmit the rotational power to the support disk 6 through the transmission rod 209, and the support disk 6 can rotate, so as to polish the butterfly valve, improving the practicability of this device, meeting the needs of users. And through the dual actions of the bidirectional threaded rod 202 and the connecting rods 205, this device can move the grinding discs 8 more precisely, making the grinding discs 8 fit tightly inside the valve body 9 and improving the polishing efficiency.

[0023] Refer to Figure 1 、 Figure 5 and Figure 6, the fixing mechanism 3 includes a first rotating column 301 which is rotatably connected to the middle of the inner bottom end of the base 1. The top end of the first rotating column 301 is fixedly connected with a first gear 302. The first rotating column 301 drives the first gear 302 to rotate. Both the left and right sides of the inner bottom end of the base 1 are rotatably connected with second rotating columns 303. The top ends of the two second rotating columns 303 are fixedly connected with second gears 304. The adjacent sides of the two second gears 304 are meshed with the first gear 302. When the first gear 302 rotates, the second gears 304 will rotate accordingly. The top ends of the two second gears 304 are rotatably connected with movable columns 305. The second gears 304 drive the movable columns 305 to perform circular motion. Through grooves 306 are provided on both the left and right sides of the top of the base 1. The inner sides of the two through grooves 306 are slidably connected with U-shaped plates 307. The U-shaped plates 307 can slide inside the through grooves 306. The bottom ends of the adjacent sides of the two U-shaped plates 307 are fixedly connected with hollow plates 308. The inner sides of the two hollow plates 308 are respectively slidably connected with the corresponding movable columns 305. The movable columns 305 push the hollow plates 308 to move. The top ends of the adjacent sides of the two U-shaped plates 307 are fixedly connected with clamping jaws 309. A rotating component is arranged inside the base 1. The rotating component includes a rotating rod 310 which is rotatably connected to the front side of the base 1. The rear end of the rotating rod 310 penetrates through the base 1 and is fixedly connected with a worm 311. The middle part of the outer side of the first rotating column 301 is fixedly connected with a worm gear 312. The worm gear 312 is meshed with the worm 311. When the worm 311 rotates, the worm gear 312 drives the first rotating column 301 to rotate; Specifically, when grinding and processing the butterfly valve, rotate the rotating rod 310. The rotating rod 310 drives the worm 311 to start rotating. Since the worm 311 is meshed with the worm gear 312, the worm gear 312 also rotates accordingly and drives the first gear 302 to start rotating through the first rotating column 301. Due to the meshing relationship between the second gear 304 and the first gear 302, the second gear 304 is also driven to rotate. As the second gear 304 rotates, it drives the movable column 305 to perform circular motion. During the movement of the movable column 305, it pushes the hollow plate 308 to move. The two hollow plates 308 on both sides move synchronously towards the center, further pushing the U-shaped plates 307 to move towards the middle. At this time, the two clamping jaws 309 on both sides are driven by the U-shaped plates 307 and can simultaneously move towards the center and clamp the valve body 9, so that the valve body 9 can be conveniently fixed. By setting anti-slip grooves 16 on the surface of the clamping jaws 309, it can be avoided that the valve body 9 is displaced due to the pushing of the grinding disc 8, reducing the workload of the staff.

[0024] Refer to Figure 7 , Figure 8 and Figure 9, the disassembly mechanism 4 includes plug-in blocks 401. The upper and lower parts on the other side of multiple grinding discs 8 are fixedly connected with plug-in blocks 401 respectively. A clamping groove 402 is formed on one side of each of the multiple plug-in blocks 401. One side inside each of the multiple mounting blocks 7 is rotatably connected with a movable rod 403. A movable plate 404 is fixedly connected to the outer side of each of the multiple movable rods 403. The movable rod 403 drives the movable plate 404 to rotate. The upper and lower sides of the movable plate 404 are rotatably connected with connecting plates 405 respectively. One end of each of the multiple connecting plates 405 is rotatably connected with a connecting seat 406. When the movable plate 404 rotates, the connecting seat 406 can be pulled to move through the connecting plate 405. A mounting plate 407 is fixedly connected to one side of each of the multiple connecting seats 406. A clamping block 408 is fixedly connected to one side of each of the multiple mounting plates 407. The mounting plate 407 drives the clamping block 408 to move. Each of the multiple plug-in blocks 401 penetrates through the corresponding mounting block 7. Each of the multiple clamping blocks 408 is engaged with the corresponding clamping groove 402. When the clamping block 408 is engaged with the clamping groove 402, the grinding disc 8 can be fixed. A reset assembly is arranged on one side inside the mounting block 7. The reset assembly includes fixing blocks 409. The multiple fixing blocks 409 are fixedly connected to the other side inside the corresponding mounting blocks 7 respectively. Hollow tubes 410 are fixedly connected to the upper and lower sides of each of the multiple fixing blocks 409. A sliding rod 411 is slidably connected inside each of the multiple hollow tubes 410. Each of the multiple sliding rods 411 is fixedly connected to the corresponding mounting plate 407. Springs 412 are arranged on the outer sides of each of the multiple hollow tubes 410. The springs 412 can push the clamping block 408 to be engaged with the clamping groove 402; Specifically, when the grinding disc 8 is severely worn and needs to be disassembled and replaced, rotate the movable rod 403. The movable rod 403 drives the movable plate 404 to rotate. As the movable plate 404 rotates, through the action of the connecting plate 405, the connecting seat 406 can be pushed to move. The movement of the connecting seat 406 further drives the clamping block 408 to move through the mounting plate 407. When the clamping block 408 moves, it will disengage from the engagement state with the clamping groove 402, so that the grinding disc 8 can be conveniently disassembled and replaced. Thus, the grinding disc 8 can be disassembled more conveniently, facilitating the operation of the staff. When the grinding disc 8 needs to be reinstalled, insert the plug-in block 401 into the mounting block 7. At this time, the spring 412 pushes the mounting plate 407 to move, and the clamping block 408 will be re-engaged with the clamping groove 402, so that the grinding disc 8 can be firmly fixed, improving the convenience of using the device.

[0025] Refer to Figure 1 、 Figure 3 and Figure 4, one end of each of the plurality of movable rods 403 penetrates through the corresponding mounting block 7 and is fixedly connected to a first knob 10. The first knob 10 facilitates the staff to rotate the movable rod 403. The top end of the bidirectional threaded rod 202 penetrates through the hollow column 201 and is fixedly connected to a second knob 11. The front end of the rotating rod 310 is fixedly connected to a handle 14. The handle 14 facilitates the staff to rotate the rotating rod 310. A sheath 15 is fixedly connected to the outer side of the handle 14; Specifically, the staff can conveniently rotate the movable rod 403 by using the first knob 10. The second knob 11 enables the staff to more conveniently rotate the bidirectional threaded rod 202. The handle 14 facilitates the staff to rotate the rotating rod 310. The sheath 15 enables the staff to comfortably hold the handle 14.

[0026] Refer to Figure 3 , Figure 4 and Figure 6 , a plurality of sliding grooves 12 are equidistantly opened at the top of the support disc 6. The bottom of each of the plurality of mounting blocks 7 is fixedly connected to a slider 13. The plurality of sliders 13 are respectively slidably connected to the corresponding sliding grooves 12. The slider 13 can only slide inside the sliding groove 12. Anti-slip grooves 16 are provided on the adjacent sides of the two clamping jaws 309. The anti-slip grooves 16 prevent the valve body 9 from slipping. The size of the U-shaped plate 307 matches the inner size of the through groove 306; Specifically, the sliding groove 12 can limit the movement of the slider 13, so that the mounting block 7 can only move within a certain range. The anti-slip grooves 16 are used to prevent the valve body 9 from shifting in position during grinding. The size of the U-shaped plate 307 matches the inner size of the through groove 306, so that the U-shaped plate 307 will not shake.

[0027] Working principle: When using this device, rotate the bidirectional threaded rod 202, the movable block 203 can move accordingly. The movable block 203 will drive the first support seat 204 to move. The first support seat 204 can pull the second support seat 206 to move through the connecting rod 205. The second support seat 206 will drive the mounting block 7 to move, and then the position of the grinding disc 8 can be moved, so as to grind and process butterfly valves of different sizes and models. And this device drives the grinding disc 8 to move through the bidirectional threaded rod 202 and the connecting rod 205, so that this device can move the grinding disc 8 more precisely, make the grinding disc 8 fit tightly with the inside of the valve body 9, and improve the grinding efficiency. When grinding, the motor 207 will drive the driving bevel gear 208 to rotate. Since the driven bevel gear 210 meshes with the driving bevel gear 208, the driven bevel gear 210 can drive the support disc 6 to rotate through the transmission rod 209, and then the grinding work can be carried out; When grinding the butterfly valve, rotate the rotating rod 310. The rotating rod 310 will drive the worm 311 to rotate. Since the worm wheel 312 meshes with the worm 311, the worm wheel 312 can drive the first gear 302 to rotate through the first rotating column 301. And because the second gear 304 meshes with the first gear 302, the second gear 304 will rotate accordingly and drive the movable column 305 to perform a circular motion. When the movable column 305 moves, it will push the hollow plate 308 to move. At this time, the two hollow plates 308 will simultaneously drive the U-shaped plate 307 to move towards the middle, and the two clamping jaws 309 can fix the valve body 9. The fixing work is more convenient and fast. And by setting anti-slip grooves 16 on the surface of the clamping jaws 309, it can prevent the valve body 9 from shifting in position due to the push of the grinding piece 8. When the grinding piece 8 is severely worn and needs to be disassembled and replaced, rotate the movable rod 403. The movable rod 403 will drive the movable plate 404 to rotate. When the movable plate 404 rotates, it can push the connecting seat 406 to move through the connecting plate 405. The connecting seat 406 can drive the clamping block 408 to move through the mounting plate 407. When the clamping block 408 moves, it will disengage from the clamping state with the clamping groove 402, and then the grinding piece 8 can be conveniently disassembled and replaced. By rotating the movable rod 403, the clamping blocks 408 on both sides can be driven to move, so that the grinding piece 8 can be disassembled more conveniently, which is convenient for the staff to operate. And when the grinding piece 8 needs to be installed, insert the plug-in block 401 into the mounting block 7, and the spring 412 can push the mounting plate 407 to move, and the clamping block 408 will engage with the clamping groove 402 accordingly, and then the grinding piece 8 can be fixed.
