Description

Technical Field

[0001] This invention relates to the field of C-shaped ball valve technology, specifically a C-shaped ball valve with anti-clogging function. Background Technology

[0002] In many industrial fields such as chemical, petrochemical, papermaking, slurry transportation, and environmental water treatment, valves are the core components of fluid control systems, and their reliability is directly related to the stability, safety, and economy of the entire process.

[0003] In the papermaking industry, when the outside temperature is high, the ball core and valve seat are in a closed state, and some pulp easily accumulates on the inner wall of the valve body. When the closure time is long, after the pulp liquid evaporates, the remaining fibers easily adhere to the inner wall of the valve body. Some of the harder fiber scale cannot be flushed away by water flow even after the ball valve is opened, which can easily lead to blockage in the valve body over time. Moreover, since the ball core in the C-shaped ball valve is only connected to the valve body through the rotating shafts at the top and bottom ends, and the middle is hollow, when the ball core and valve seat are in a closed state and the liquid applies high pressure to the ball core, the overall structure of the ball core and valve body shaft contact is prone to fatigue, causing slight loosening between the ball core and valve seat. As a result, pulp liquid can easily seep out from the valve seat and ball core. Furthermore, with the baking in the high-temperature environment, the continuously seeping pulp liquid is easily dried and accumulated in the inner wall of the valve body, exacerbating the blockage.

[0004] Therefore, this invention proposes a C-shaped ball valve with anti-clogging function. Summary of the Invention

[0005] The purpose of this invention is to provide a C-shaped ball valve with anti-clogging function to solve the problems in the prior art where the dried pulp fibers easily adhere to the inside of the valve body, causing blockage, and the overall structure at the joint between the ball core and the valve body is prone to fatigue, causing the pulp liquid to easily seep out from the valve seat and the ball core, and after drying, adhere to the inner wall of the valve body, exacerbating the blockage.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a C-shaped ball valve with anti-clogging function, the C-shaped ball valve comprising a valve body, a ball core, a drive shaft, a support shaft, a valve seat, a drive seat, a rotary handle, a scraping assembly, and a reinforcing assembly; the ball core is rotatably connected to the valve body via the drive shaft and the support shaft, the drive shaft is fixedly connected to the top of the ball core, the support shaft is fixedly connected to the bottom of the ball core, the valve seat is fixedly connected inside the valve body, the drive seat is fixedly connected to the top of the valve body, the rotary handle is rotatably connected to the drive seat, and the end of the rotary handle is meshed with the drive shaft within the drive seat via a worm gear structure; when the rotary handle rotates, it drives the ball core to rotate along the valve body; the scraping assembly is fixedly connected to the ball core. Furthermore, the scraping component is fitted to the inner wall of the valve body, the reinforcing component is slidably connected to the support shaft and the ball core, the ball core and valve seat closing reinforcing component is inserted into the bottom of the ball core, and the ball core and valve seat opening reinforcing component retracts into the drive shaft; during the opening and closing of the ball core, the scraping component can scrape off the pulp fibers on the inner wall of the valve body to prevent residue accumulation from causing blockage. At the same time, when the ball core and valve seat are in the open state, the reinforcing component will tighten into the drive shaft, and the liquid can flow quickly through the empty space in the middle of the ball core. When the ball core and valve seat are in the closed state, the reinforcing component will be inserted into the bottom of the ball core, which will reinforce the overall structure of the ball core and prevent fatigue loosening of the overall structure at the joint between the ball core and the valve body under high pressure.

[0007] Preferably, the scraping assembly includes scraper one and scraper two; scraper one and scraper two are both fitted against the inner wall of the valve body. When the ball core is closed with the valve seat, scraper one and scraper two are located on both sides of the valve body's discharge pipe. After the ball core is opened with the valve, scraper two is fitted against the valve seat. During the process of the ball core rotating 90 degrees clockwise and opening with the valve seat, scraper one and scraper two will rotate around the axis of the ball core to scrape off the fiber scale on the inner wall of the valve body. During the opening of the ball core, the ball core body can simultaneously scrape off the inner wall of the valve body, while scraper one and scraper two scrape off the remaining area. As the ball core opens, the high-flow-rate pulp will flush away the scraped fiber scale and finally discharge it from the right side of the valve body.

[0008] Preferably, the reinforcement assembly includes a plug groove, a reinforcement rod, a rotating column, a guide groove, a drive column, and a sealing component; the plug groove is located below the ball core and extends into the support shaft; the reinforcement rod passes through the drive shaft and the drive seat and is slidably connected vertically at their centers; the rotating column is fixedly connected to the top of the reinforcement rod; the guide groove is located on the outer wall of the rotating column; the bottom of the drive column is fixedly connected to the drive seat via a support rod frame, and the top end of the drive column is slidably connected to the guide groove; the sealing component is slidably connected vertically to the plug groove; during the opening of the ball core, the rotating column will follow... The drive shaft rotates 90 degrees clockwise, and through the guide groove and drive column, it drives the rotating column to lift the reinforcing rod and retract it into the drive shaft. This prevents the reinforcing rod from obstructing the flow of pulp liquid and affecting the flow rate. When the ball core rotates 90 degrees counterclockwise and closes with the valve seat, the reinforcing rod will descend and push the sealing part into the insertion groove, so that it is inserted into the insertion groove. In this closed and sealed state, the ball core improves the overall stability of the ball core and prevents metal fatigue of the overall structure at the joint between the ball core and the valve body. Otherwise, the pulp liquid will slowly seep out and, after drying in a high-temperature environment, the fibers will adhere to the inner wall of the valve body and cause blockage.

[0009] Preferably, the sealing component includes a sealing block, an abutment plane, and an elastic element; the sealing block is slidably connected to the insertion slot, the abutment plane is horizontally positioned at the top of the sealing block, the bottom of the elastic element is fixedly connected to the insertion slot, and the top is fixedly connected to the bottom surface of the sealing block; during the process of the ball core rotating 90 degrees counterclockwise and closing the valve seat, the bottom of the reinforcing rod will first abut against the abutment plane at the top of the sealing block, and then push the sealing block as a whole to overcome the elastic force of the elastic element and descend into the insertion slot. After the ball core rotates 90 degrees clockwise and opens the valve seat, the reinforcing rod will retract into the drive shaft, and the sealing block will also be pushed upward by the elastic element to seal the insertion slot and prevent the insertion slot from increasing the resistance of the pulp fluid passing through it.

[0010] Preferably, the bottom surface of the reinforcing rod and the top surface of the sealing block are inclined arc surfaces, and the arc is consistent with the arc of the inner wall of the valve body; after the ball core and the valve body are in the open state, the bottom surface of the reinforcing rod and the top surface of the sealing block will form a smooth curved surface with the inner arc surface of the ball core, reducing the resistance to the pulp fluid.

[0011] Preferably, the C-shaped ball valve further includes a sealing assembly, which is slidably connected to the ball core. After the reinforcing rod is inserted into the insertion groove, the sealing assembly abuts against the valve seat to enhance the sealing between the ball core and the valve seat.

[0012] Preferably, the sealing assembly includes an annular groove, a sliding ring, a sealing gasket, a second elastic element, a bottom push rod, a top push rod, and a synchronization control element. The annular groove is formed on the outer surface of the ball core. The sliding ring is slidably connected to the annular groove. The sealing gasket is fixedly connected to the sliding ring. The second elastic element is located between the sliding ring and the annular groove. The bottom push rod and the top push rod are both slidably connected to the ball core. The bottom push rod and the top push rod have the same length and both have inclined surfaces at their ends. The top push rod is fixedly connected to the upper part of the sliding ring, and the bottom push rod is fixedly connected to the lower part of the sliding ring. The synchronization control element is slidably connected to the lower part of the reinforcing rod. During the process of the ball core closing with the valve seat and the reinforcing rod descending, after the reinforcing rod passes the top push rod and the bottom push rod, it will push the sliding ring to overcome the tension of the second elastic element through the inclined surfaces at the ends of the top push rod and the bottom push rod, moving it along the annular groove towards the valve seat until the ball core and the valve seat are in a closed state. Then, the sealing gasket on the sliding ring will press against the valve seat to seal, which can further seal the ball core and prevent long-term wear of the ball core from causing sealing problems.

[0013] Preferably, the synchronization control component includes a vertical groove, a sliding block, a locking block, a magnet, and a receiving groove; the vertical groove is located on the outer side below the reinforcing rod, the sliding block is slidably connected to the vertical groove, the locking block is fixedly connected to the outer side of the sliding block, the magnet is fixedly connected to the lower side of the locking block, and the receiving groove is located on the inclined surface of the bottom push rod; when the reinforcing rod is inside the drive shaft, the bottom of the sliding block will be located below the top push rod. During the process of the starting ball core and valve seat closing and the reinforcing rod descending accordingly, the top push rod will first slide in the vertical groove below the reinforcing rod. When the bottom of the reinforcing rod abuts against the bottom push rod, the top of the vertical groove will also abut against the top push rod. At this time, the continuing descent of the reinforcing rod will smoothly drive the sliding block. As the moving ring moves toward the valve seat and the reinforcing rod continues to descend, the locking block on the outside of the sliding block engages with the receiving groove on the bottom push rod. The sliding block can slide along the vertical groove, always maintaining the pushing state of the bottom push rod, thereby achieving synchronous movement of the bottom push rod and the top push rod. This prevents the sealing gasket from tilting and deforming, which could lead to sealing failure. As the ball core and valve seat open and the reinforcing rod rises, the bottom push rod, through the attraction and resistance of the magnet, will push the sliding block down until it reaches the bottom. At this point, the magnet will disengage from the bottom push rod, and at the instant the bottom push rod disengages from the sliding block, the top push rod will also enter the vertical groove. Both of these actions will simultaneously release the thrust generated on the sliding ring.

[0014] Preferably, the sealing block is provided with a receiving groove on the upper outer peripheral wall; the shape of the receiving groove matches the end of the bottom push rod; as the ball core and valve seat opening reinforcement rod rise, the sealing block will be pushed up by the elastic element and become flush with the inner arc surface of the ball core, and at the same time, the end of the bottom push rod will be in the receiving groove during the rising process.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. During the process of the ball core rotating 90 degrees clockwise and the valve seat opening, scraper one and scraper two will rotate around the axis of the ball core to scrape off the fiber scale on the inner wall of the valve body. During the opening of the ball core, the ball core body can simultaneously scrape off the inner wall of the valve body, while scraper one and scraper two scrape off the remaining areas that the ball core has not yet passed. As the ball core opens, the high-flow-rate pulp will flush away the scraped fiber scale and finally discharge it from the right side of the valve body, thus playing a role in preventing blockage.

[0017] 2. When the ball core rotates 90 degrees clockwise and opens with the valve seat, the reinforcing rod will rise completely and retract into the drive shaft. This prevents the reinforcing rod from obstructing the flow of pulp liquid and affecting the flow rate. At this time, the sealing block will also be pushed upward by the elastic element to seal the insertion slot and prevent the insertion slot from increasing the resistance of the pulp fluid. When the ball core rotates 90 degrees counterclockwise and closes with the valve seat, the reinforcing rod will descend and insert into the insertion slot. This improves the overall stability of the ball core when the ball core and valve seat are closed and sealed, preventing metal fatigue at the joint between the ball core and the valve body. Otherwise, the pulp liquid will slowly seep out and, after drying in a high-temperature environment, the fibers will adhere to the inner wall of the valve body, causing blockage.

[0018] 3. In the process of closing the ball core and valve seat and lowering the reinforcing rod, after the reinforcing rod passes the top push rod and bottom push rod, it will simultaneously push the sliding ring to overcome the tension of the elastic element two through the inclined surfaces at the ends of the top push rod and bottom push rod, and move smoothly towards the valve seat along the ring groove until the ball core and valve seat are in a closed state. Then, the sealing gasket on the sliding ring will press against the valve seat to seal, which can further seal the ball core and prevent long-term wear of the ball core from causing sealing problems.

[0029] 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.

[0030] Please see Figures 1 to 9 This invention provides a C-shaped ball valve with anti-clogging function, the technical solution of which is as follows:

[0031] Reference Figure 1 and Figure 2A C-shaped ball valve with anti-clogging function is disclosed. The C-shaped ball valve includes a valve body 1, a ball core 2, a drive shaft 21, a support shaft 22, a valve seat 3, a drive seat 4, a handle 41, a scraping assembly 5, and a reinforcing assembly 6. The ball core 2 is rotatably connected to the valve body 1 via the drive shaft 21 and the support shaft 22. The drive shaft 21 is fixedly connected to the top of the ball core 2, and the support shaft 22 is fixedly connected to the bottom of the ball core 2. The valve seat 3 is fixedly connected inside the valve body 1, and the drive seat 4 is fixedly connected to the top of the valve body 1. The handle 41 is rotatably connected to the drive seat 4. The end of the handle 41 is meshed with the drive shaft 21 inside the drive seat 4 via a worm gear structure. When the handle 41 rotates, the drive ball core 2 rotates along the valve body 1. The scraping assembly 5 is fixedly connected to the ball core 2 and is fitted against the inner wall of the valve body 1. The reinforcing assembly 6 is slidably connected to the support shaft 22 and the ball core 2. The ball core 2 and the valve seat 3 are closed. The reinforcing assembly 6 is inserted into the bottom of the ball core 2. The ball core 2 and the valve seat 3 are closed. The reinforcing component 6 retracts into the drive shaft 21. In this invention, rotating the handle 41 forward causes the drive shaft 21 to rotate via the worm gear mechanism within the drive seat 4. This, in turn, drives the ball core 2 to rotate 90 degrees clockwise. At this time, the ball core 2 will be in an open state with the valve seat 3, allowing the pulp liquid to flow from the left side of the valve body 1 through the central space of the ball core 2 to the right side of the valve body 1. Reverse rotation of the handle 41 drives the ball core 2 to rotate 90 degrees counterclockwise, closing the ball core 2 with the valve seat 3. During the opening and closing process, the scraping component 5 can scrape off the pulp fibers on the inner wall of the valve body 1 to prevent residue accumulation and blockage. At the same time, when the ball core 2 and the valve seat 3 are in the open state, the reinforcing component 6 will tighten inside the drive shaft 21, and the liquid can flow quickly through the empty space in the middle of the ball core 2. When the ball core 2 and the valve seat 3 are in the closed state, the reinforcing component 6 will be inserted into the bottom of the ball core 2 to reinforce the overall structure of the ball core 2 and prevent fatigue loosening of the overall structure at the joint between the ball core 2 and the valve body 1 under high pressure.

[0032] Reference Figure 3 and Figure 4 The scraping assembly 5 includes a first scraper 51 and a second scraper 52. Both the first scraper 51 and the second scraper 52 are fitted against the inner wall of the valve body 1. When the ball core 2 and the valve seat 3 are closed, the first scraper 51 and the second scraper 52 are located on both sides of the discharge pipe of the valve body 1. When the ball core 2 and the valve seat 3 are opened, the second scraper 52 fits against the valve seat 3. During the process of the ball core 2 rotating 90 degrees clockwise and opening the valve seat 3, the first scraper 51 and the second scraper 52 will rotate around the axis of the ball core 2 to scrape off the fiber scale on the inner wall of the valve body 1. During the opening of the ball core 2, the body of the ball core 2 can simultaneously scrape off the inner wall of the valve body 1, while the first scraper 51 and the second scraper 52 scrape off the remaining area. As the ball core 2 opens, the high-flow-rate pulp will flush away the scraped fiber scale and finally discharge it from the right side of the valve body 1.

[0033] Reference Figures 5 to 7 The reinforcing component 6 includes a plug groove 61, a reinforcing rod 62, a rotating column 63, a guide groove 64, a drive column 65, and a sealing component 66. The plug groove 61 is located below the ball core 2 and extends into the support shaft 22. The reinforcing rod 62 passes through the drive shaft 21 and the drive seat 4 and is slidably connected vertically at their centers. The rotating column 63 is fixedly connected to the top of the reinforcing rod 62. The guide groove 64 is located on the outer wall of the rotating column 63. The bottom of the drive column 65 is fixedly connected to the drive seat 4 via a support rod frame, and the top end of the drive column 65 is slidably connected to the guide groove 64. The sealing component 66 is slidably connected vertically to the plug groove 61. During the process of the ball core 2 rotating 90 degrees clockwise and opening the valve seat 3, the rotating column 63 will follow the drive shaft. 21. Rotate 90 degrees clockwise. During this rotation, the guide groove 64 will cooperate with the drive column 65 to drive the rotating column 63 to lift the reinforcing rod 62. After the ball core 2 stops rotating 90 degrees clockwise, the reinforcing rod 62 will rise completely into the drive shaft 21. This prevents the reinforcing rod 62 from blocking the passing pulp liquid and affecting the flow rate. When the ball core 2 rotates 90 degrees counterclockwise and closes with the valve seat 3, the reinforcing rod 62 will descend and push the sealing part 66 into the insertion groove 61, so that it is inserted into the insertion groove 61. In this way, when the ball core 2 and the valve seat 3 are closed and sealed, the overall stability of the ball core 2 is improved, and the overall structure of the ball core 2 and the valve body 1 shaft contact structure is prevented from experiencing metal fatigue, which would cause the pulp liquid to slowly seep out and, after drying in a high-temperature environment, the fiber body to adhere to the inner wall of the valve body 1 and cause blockage.

[0034] Reference Figure 6 and Figure 7 The sealing component 66 includes a sealing block 661, an abutment plane 662, and an elastic element 663. The sealing block 661 is slidably connected to the insertion groove 61. The abutment plane 662 is horizontally positioned at the top of the sealing block 661. The bottom of the elastic element 663 is fixedly connected to the insertion groove 61, and the top is fixedly connected to the bottom surface of the sealing block 661. During the process of the ball core 2 rotating counterclockwise 90 degrees and closing the valve seat 3, the bottom of the reinforcing rod 62 will first abut against the abutment plane 662 at the top of the sealing block 661, and then push the sealing block 661 as a whole to overcome the elastic force of the elastic element 663 and descend into the insertion groove 61. After the ball core 2 rotates clockwise 90 degrees and opens the valve seat 3, the reinforcing rod 62 will retract into the drive shaft 21, and the sealing block 661 will also be pushed upward by the elastic element 663 to seal the insertion groove 61 and prevent the insertion groove 61 from increasing the resistance of the pulp fluid passing through it.

[0035] Reference Figure 7The bottom surface of the reinforcing rod 62 and the top surface of the sealing block 661 are set with inclined arc surfaces, and the arc is consistent with the arc of the inner wall of the valve body 1. After the ball core 2 and the valve body 1 are in the open state, the bottom surface of the reinforcing rod 62 and the top surface of the sealing block 661 will form a smooth curved surface with the inner arc surface of the ball core 2, reducing the resistance to the pulp fluid.

[0036] Reference Figure 2 and Figure 8 The C-shaped ball valve also includes a sealing component 7, which is slidably connected to the ball core 2. After the reinforcing rod 62 is inserted into the insertion groove 61, the sealing component 7 abuts against the valve seat 3 to enhance the sealing between the ball core 2 and the valve seat 3.

[0037] Reference Figure 6 and 8 The sealing assembly 7 includes an annular groove 71, a sliding ring 72, a sealing gasket 73, an elastic element 74, a bottom push rod 75, a top push rod 76, and a synchronization control element 77. The annular groove 71 is formed on the outer surface of the ball core 2. The sliding ring 72 is slidably connected to the annular groove 71. The sealing gasket 73 is fixedly connected to the sliding ring 72. The elastic element 74 is located between the sliding ring 72 and the annular groove 71. The bottom push rod 75 and the top push rod 76 are both slidably connected to the ball core 2. The bottom push rod 75 and the top push rod 76 have the same length and both have beveled ends. The top push rod 76 is fixedly connected to the top of the sliding ring 72. The bottom push rod 75... The synchronous control component 77 is slidably connected to the lower part of the reinforcing rod 62 and the lower part of the sliding ring 72. During the process of the ball core 2 and valve seat 3 being closed and the reinforcing rod 62 descending, after the reinforcing rod 62 passes the top push rod 76 and bottom push rod 75, it will push the sliding ring 72 to overcome the tension of the elastic component 74 through the inclined surfaces at the ends of the top push rod 76 and bottom push rod 75, and move it along the ring groove 71 towards the valve seat 3 until the ball core 2 and valve seat 3 are in a closed state. Then, the sealing gasket 73 on the sliding ring 72 will press against the valve seat 3 to seal it, which can further seal the ball core 2 and prevent the ball core 2 from having a sealing problem due to long-term wear.

[0038] Reference Figure 8The synchronization control component 77 includes a vertical groove 771, a sliding block 772, a locking block 773, a magnet 774, and a receiving groove 775. The vertical groove 771 is located on the outer side below the reinforcing rod 62. The sliding block 772 is slidably connected to the vertical groove 771. The locking block 773 is fixedly connected to the outer side of the sliding block 772. The magnet 774 is fixedly connected to the lower part of the locking block 773. The receiving groove 775 is located on the inclined surface of the bottom push rod 75. The bottom of the reinforcing rod 62 is connected to... When the bottom of the drive shaft 21 is flush with and inside the drive shaft 21, the bottom of the sliding block 772 will be located below the push rod 76. As the starting ball core 2 and valve seat 3 close and the reinforcing rod 62 descends, the push rod 76 will first slide in the vertical groove 771 below the reinforcing rod 62. After the bottom of the reinforcing rod 62 abuts against the bottom push rod 75, the top of the vertical groove 771 will also abut against the push rod 76. At this time, the continuing descent of the reinforcing rod 62 will smoothly drive the sliding ring 72 to move towards the valve seat 3. As the reinforcing rod 62 continues to descend, the locking block 773 on the outer side of the sliding block 772 will engage with the receiving groove 775 on the bottom push rod 75. The sliding block 772 can slide along the vertical groove 771, always maintaining the pushing state of the bottom push rod 75. The top push rod 76 will be simultaneously located on the smooth outer wall of the reinforcing rod 62 above the vertical groove 771, also maintaining the pushing state of the top push rod 76, thereby achieving synchronous movement of the bottom push rod 75 and the top push rod 76, preventing the sealing gasket 73 from tilting and deforming, which would lead to sealing failure. As the ball core 2 and valve seat 3 open the reinforcing rod 62 and it rises, the bottom push rod 75 will push the sliding block 772 down through the attraction and resistance force with the magnet 774 until it reaches the bottom. The magnet 774 will disengage from the bottom push rod 75, and at the moment the bottom push rod 75 disengages from the sliding block 772, the top push rod 76 will also enter the vertical groove 771. Both will simultaneously release the thrust generated on the sliding ring 72.

[0039] Reference Figure 9 The sealing block 661 is provided with a receiving groove 6611 on its upper outer peripheral wall; the shape of the receiving groove 6611 matches the end of the bottom push rod 75; as the ball core 2 and valve seat 3 open the reinforcing rod 62, the sealing block 661 will be pushed up by the elastic element 663 and become flush with the inner arc surface of the ball core 2, while the end of the bottom push rod 75 will be in the receiving groove 6611 during the rising process.

[0040] The working principle of this invention is as follows: When the handle 41 is rotated in the forward direction, the handle 41 will drive the drive shaft 21 to rotate through the worm gear mechanism in the drive seat 4. When the ball is rotated 90 degrees clockwise, the ball core 2 will be in the open state with the valve seat 3. The pulp liquid will flow from the left pipe of the valve body 1 through the middle space of the ball core 2 to the right pipe of the valve body 1. When the handle 41 is rotated in the reverse direction to drive the ball core 2 to rotate 90 degrees counterclockwise, the ball core 2 will be in the closed state with the valve seat 3.

[0041] As the ball core 2 rotates 90 degrees clockwise and the valve seat 3 opens, scraper 1 51 and scraper 2 52 rotate around the axis of the ball core 2 to scrape off the fiber scale on the inner wall of the valve body 1. During the opening of the ball core 2, the ball core 2 body can simultaneously scrape off the inner wall of the valve body 1. Scraper 1 51 and scraper 2 52 scrape off the remaining areas that the ball core 2 has not yet passed. As the ball core 2 opens, the high-flow-rate pulp will flush away the scraped fiber scale and finally discharge it from the right side of the valve body 1.

[0042] As the ball core 2 rotates 90 degrees clockwise and the valve seat 3 opens, the rotating column 63 will rotate 90 degrees clockwise along with the drive shaft 21. During this rotation, the guide groove 64 will cooperate with the drive column 65, driving the rotating column 63 to raise the reinforcing rod 62. After the ball core 2 stops rotating 90 degrees clockwise, the reinforcing rod 62 will fully rise and retract into the drive shaft 21, preventing it from obstructing the flow of pulp liquid and affecting the flow rate. At this time, the sealing block 661 will also be pushed upwards by the elastic element 663, sealing the insertion slot 61 and preventing the insertion slot 61 from increasing the flow of pulp fluid. Resistance; When the ball core 2 rotates counterclockwise 90 degrees and closes with the valve seat 3, the reinforcing rod 62 will descend again. The bottom of the reinforcing rod 62 will first abut against the abutting plane 662 at the top of the sealing block 661, and then push the sealing block 661 as a whole to overcome the elastic force of the elastic element 663 and descend into the insertion groove 61, so that the reinforcing rod 62 itself is inserted into the insertion groove 61. In this way, when the ball core 2 and the valve seat 3 are closed and sealed, the overall stability of the ball core 2 is improved, and the overall structure at the shaft connection between the ball core 2 and the valve body 1 is prevented from experiencing metal fatigue, which would cause the pulp liquid to slowly seep out and, after drying in a high-temperature environment, the fiber body to adhere to the inner wall of the valve body 1 and cause blockage.

[0043] Simultaneously, as the ball core 2 and valve seat 3 close and the reinforcing rod 62 descends, the push rod 76 will first slide in the vertical groove 771 below the reinforcing rod 62. When the bottom of the reinforcing rod 62 abuts against the bottom push rod 75, the top of the vertical groove 771 will also abut against the push rod 76. At this time, the continuing descent of the reinforcing rod 62 will smoothly drive the sliding ring 72 to move towards the valve seat 3. As the reinforcing rod 62 continues to descend, the locking block 773 on the outside of the sliding block 772 will engage with the receiving groove 775 on the bottom push rod 75. The sliding block 772 can slide along the vertical groove 771, always maintaining the pushing state of the bottom push rod 75. The push rod 76 will simultaneously be in the vertical groove 771. The outer wall of the reinforcing rod 62 above the groove 771 is smooth, and the push rod 76 is also pushed, so as to realize the synchronous movement of the bottom push rod 75 and the push rod 76, preventing the sealing gasket 73 from tilting and deforming, which would lead to sealing failure. As the ball core 2 and valve seat 3 open the reinforcing rod 62, the bottom push rod 75 will push the sliding block 772 down through the attraction and resistance force with the magnet 774 until it reaches the bottom. The magnet 774 will disengage from the bottom push rod 75. At the moment the bottom push rod 75 disengages from the sliding block 772, the push rod 76 will also enter the vertical groove 771. Both will release the thrust generated on the sliding ring 72 at the same time.
