Description

Technical Field

[0001] The present application relates to the field of filter ball valve equipment, and in particular to a filter ball valve that is convenient for replacing a filter element. Background Art

[0002] In the civil or industrial fields, various water supply, heating, and gas supply pipeline systems are installed with various metering instruments and equipment. As the use time increases, impurities in various flow media will accumulate in the pipelines and various components, causing pipeline blockage or component wear, affecting the accuracy of various metering instruments and the service life of the equipment.

[0003] In order to solve these problems, people install filtering ball valves in the pipeline to filter and clean the impurities accumulated in the pipeline during long-term use to ensure the normal operation of instruments and equipment.

[0004] In the related art, during the long-term use of the filter ball valve, as impurities accumulate, the filter screen of the filter ball valve needs to be cleaned. At present, the conventional way to clean the filter screen is to block the water flow in the pipeline to stop the water supply, and then disassemble the ball valve to replace the filter screen. In this traditional replacement method, when replacing the filter screen in the ball valve, the pipeline must be cut off to stop the flow, and then the filter screen can be replaced. This means that the pipeline cannot supply water during the filter screen replacement process, which will affect the water use of pipelines in civil or industrial fields. Summary of the invention

[0005] The present application provides a filter ball valve that is easy to replace the filter element. The purpose is to not affect the normal water supply of the pipeline during the process of replacing the ball valve filter, so that the filter replacement and pipeline water supply can be carried out at the same time, which is beneficial to ensure pipeline water use in civil or industrial fields.

[0006] The present application provides a filter ball valve that is convenient for replacing a filter element, and adopts the following technical solution: A filter ball valve for easy replacement of a filter element, comprising a valve body, the valve body consisting of an upper shell and a lower shell, a valve ball being arranged in the lower shell, a first channel and a second channel being respectively opened on the valve ball, the first channel and the second channel both pass through the valve ball, and the first channel and the second channel are in a "cross" shape as a whole, a mounting hole for connecting the first channel and the second channel is opened through the peripheral side of the outer wall of the lower shell, the openings of the first channel and the second channel are both in the same height as the mounting hole, and filter screens are installed at the openings of the first channel and the second channel; Two sets of sealing assemblies are added in the lower shell, and the two sets of sealing assemblies are distributed on the left and right sides of the valve ball. The sealing assembly includes a first sealing plate and a second sealing plate. The first sealing plate and the second sealing plate are both slidably arranged in the lower shell along the vertical direction. The first sealing plate is located outside the valve ball, and the second sealing plate is located above the side of the valve ball. The filter is located between the corresponding first sealing plate and the second sealing plate. A first drive assembly and a second drive assembly are provided in the upper shell body, the first drive assembly includes a first drive wheel and a second drive wheel, the first drive wheel is connected to the first sealing plate, the second drive wheel is connected to the second sealing plate, the first drive wheel is used to drive the first sealing plate to slide in the vertical direction, the second drive wheel is used to drive the second sealing plate to slide in the vertical direction, and the second drive assembly is used to drive the valve ball to rotate in the lower shell body.

[0007] By adopting the above technical solution, with long-term use, when the filter screens at the openings on both sides of the first channel need to be replaced, the first driving wheel and the second driving wheel drive the first sealing plate and the second sealing plate on both sides of the valve ball to rise until the first sealing plate rises to the same height as the mounting hole on the lower shell and the second sealing plate extends from the inside of the valve ball. In this state, the first sealing plate seals the corresponding mounting hole on the lower shell, and the second sealing plate rises to the top of the valve ball and disconnects from the valve ball. Then, the second driving assembly drives the valve ball to rotate 90°, so that the first channel and the second channel switch positions. After the valve ball rotates 90°, in this state, the second channel remains connected to the pipeline, the second channel is used for pipeline water supply, and the first pipeline and the second pipeline remain vertical.

[0008] When the first channel and the second channel are switched, the first driving wheel and the second driving wheel drive the corresponding first sealing plate and the second sealing plate to descend until the first sealing plate descends to the bottom of the mounting hole and the bottom of the second sealing plate extends into the valve ball to seal the first channel. In this state, the first sealing plate descends to the bottom of the mounting hole so that the mounting hole is reopened, and the two second sealing plates seal the first channel, which can effectively prevent the water in the pipeline from leaking from the first channel. At this time, the filter screens on both sides of the first pipeline can be taken out through the mounting hole for replacement.

[0009] In summary: the function of the first sealing plate is to seal or open the corresponding installation hole, and the function of the second sealing plate is to seal the first pipeline or the second pipeline.

[0010] In this arrangement, the first channel and the second channel are opened on the valve ball, and when the first channel is connected to the pipeline for water supply, the filter screen on the second channel is replaced. When the filter screen on the first channel needs to be replaced, the positions of the first channel and the second channel are switched, so that the second channel is connected to the pipeline for water supply, and the filter screen on the first channel can be replaced.

[0011] By using the first channel and the second channel, when the filter on the first channel needs to be replaced, the second channel is used to maintain communication with the pipeline, and water is supplied through the second pipeline. This allows the filter on the first channel to be replaced while the second channel is used to maintain communication with the pipeline for water supply. When the filter on the second channel needs to be replaced, the first channel is used to maintain communication with the pipeline for water supply. This allows the replacement of the filter and pipeline water supply to be carried out at the same time, which is beneficial to ensure that pipeline water use in the civil or industrial fields is not affected.

[0012] Preferably, a first rotating shaft is installed on the side wall of the upper shell body along the horizontal direction, and a first bevel gear is integrally installed on the end of the first rotating shaft along the vertical direction, a second rotating shaft is installed inside the upper shell body along the horizontal direction, and a second bevel gear is integrally installed on one end of the second rotating shaft close to the first rotating shaft, the first bevel gear and the second bevel gear are meshed and connected, the first driving wheel is integrally sleeved on the second rotating shaft, a first rack is installed in the upper shell body along the vertical direction, the first rack is meshed and connected with the first driving wheel, and a first connecting rod is integrally connected to the side of the first rack away from the first driving wheel along the vertical direction, the first connecting rod is in an "L"-shaped structure, the top of the first connecting rod is integrally connected to the first rack, the bottom of the first connecting rod is integrally connected to the second connecting rod, and the second connecting rod is in an "L"-shaped structure as a whole, and the first sealing plates on both sides of the valve ball are respectively integrally connected to the left and right sides of the second connecting rod.

[0013] By adopting the above technical solution, when it is used, the first rotating shaft is rotated, and the first bevel gear is driven to rotate through the first rotating shaft. The first bevel gear is meshed with the second bevel gear during the rotation process, thereby driving the second bevel gear to rotate. When the second bevel gear rotates, it synchronously drives the second rotating shaft to rotate, and drives the first driving wheel to rotate through the second rotating shaft. During the rotation of the first driving wheel, it meshes with the first rack and drives the first rack to slide in the vertical direction. When the first rack slides in the vertical direction, it synchronously drives the first connecting rod, the second connecting rod and the two first sealing plates to slide up and down in the vertical direction.

[0014] Preferably, the second driving wheel is integrally mounted on the second rotating shaft, a second rack is installed in the upper shell body along the vertical direction, the second rack is meshed and connected with the second driving wheel, the bottom of the second rack is connected to the second sealing plate through a horizontally arranged third connecting rod, the top of the second rack is integrally connected to a fourth connecting rod, and the end of the fourth connecting rod away from the second rack is connected to the second sealing plate on the other side of the valve ball through the third connecting rod.

[0015] By adopting the above technical solution, when in use, the second rotating shaft rotates and simultaneously drives the second driving wheel to rotate, and the second driving wheel engages with the second rack during the rotation process, and drives the second rack to lift and slide in the vertical direction. During the lifting and sliding process, the second rack drives the second sealing plates on both sides of the valve ball to lift and slide in the vertical direction through the third connecting rod and the fourth connecting rod.

[0016] Preferably, the second driving assembly includes a driving motor, a screw, a lifting plate, a lifting seat, a rotating seat, a third bevel gear, a fourth bevel gear and a third rotating shaft; the driving motor is a forward and reverse motor, the driving motor is mounted on the top of the upper shell body, the driving end of the driving motor is vertically facing downward, the screw is mounted in the upper shell body along the vertical direction, the top of the screw extends upwardly from the upper shell body and is connected to the driving end of the driving motor, the lifting plate is sleeved on the screw in the horizontal direction, and the lifting plate is threadably connected to the screw, one end of the lifting plate away from the screw is integrally connected to the lifting seat, the lifting seat is horizontally arranged, the rotating seat is integrally mounted on the top of the lifting seat, the third bevel gear is rotatably mounted on the rotating seat, and the third bevel gear is located below the second rotating shaft, the fourth bevel gear is integrally sleeved on the second rotating shaft, the top of the third rotating shaft is inserted into the third bevel gear, the third rotating shaft is integrally connected to the third bevel gear, and the bottom of the third rotating shaft is connected to the top of the valve ball.

[0017] By adopting the above technical solution, when the filter on the first channel needs to be replaced, the first driving wheel and the second driving wheel drive the corresponding first sealing plate and the second sealing plate to rise. When the first sealing plate rises to the position of the corresponding mounting hole and the second sealing plate rises to above the valve ball, the driving motor is turned on, and the driving motor drives the screw to rotate. During the rotation process, the screw cooperates with the lifting plate thread to drive the lifting plate to rise. When the lifting plate rises, the lifting seat and the rotating seat are simultaneously driven to rise until the third bevel gear is meshed and connected with the fourth bevel gear. At this time, the second rotating shaft is rotated to drive the fourth bevel gear to rotate, and the third bevel gear is driven to rotate by the fourth bevel gear. During the rotation of the third bevel gear, the third rotating shaft is driven to rotate, and then the valve ball is driven to rotate by the third rotation.

[0018] When the valve ball rotates 90° driven by the third rotating shaft so that the first channel and the second channel switch positions, the driving motor reverses to make the lifting plate descend, and drives the third bevel gear to descend through the lifting seat and the rotating seat until the third bevel gear and the fourth bevel gear are disengaged. In this state, the valve ball no longer rotates. In this state, the first sealing plate is located at the corresponding mounting hole position, and the second sealing plate is located above the valve ball.

[0019] When the valve ball position is rotated, the first rotating shaft and the second rotating shaft are reversed, and the first driving wheel and the second driving wheel drive the corresponding first sealing plate and the second sealing plate to descend until the first sealing plate is located below the corresponding mounting hole and the bottom of the second sealing plate extends into the valve ball to seal the first channel. When the first sealing plate and the second sealing plate are lowered to the specified position, the filter screen at the opening of the first pipeline can be taken out through the corresponding mounting hole for replacement.

[0020] Preferably, teeth are integrally formed on the circumference of the first driving wheel and the second driving wheel, and the teeth on the first driving wheel and the second driving wheel are each one quarter of the circumference thereof.

[0021] By adopting the above technical solution, the purpose of keeping the first rack and the second rack stationary during the rotation of the valve ball is: because the first rack and the second rack are installed inside the valve body, if the first rack and the second rack continue to rise during the rotation of the valve ball, once the valve ball has not rotated 90°, the first rack and the second rack have already abutted against the top of the valve body, that is, at this time, the first rack and the second rack can no longer continue to rise, but the valve ball has not rotated 90°, which makes the first rack and the second rack interfere with the rotation of the valve ball and affect the position of the valve ball. Therefore, during the rotation of the valve ball, keeping the first rack and the second rack stationary can effectively prevent the first rack and the second rack from interfering with the rotation of the valve ball.

[0022] Preferably, a sliding groove for sliding the second sealing plate is formed through the top circumference of the valve ball.

[0023] By adopting the above technical solution, the second sealing plate extends into the interior of the valve ball through the corresponding sliding groove.

[0024] Preferably, a rubber ring is installed around the opening of the slide groove.

[0025] By adopting the above technical solution, the rubber ring is soft and elastic. When the second sealing plate extends into the valve ball through the slide groove, the rubber ring can adhere to the second sealing plate through its own elasticity, thereby effectively ensuring the stability of the second sealing plate after extending into the valve ball without causing damage to the second sealing plate.

[0026] Preferably, a hand wheel is installed at the end of the first rotating shaft.

[0027] By adopting the above technical solution, it is more convenient to rotate the first rotating shaft using the hand wheel, and the experience is better.

[0028] In summary, the present application includes at least one of the following beneficial technical effects: 1. By opening the first channel and the second channel on the valve ball, when the first channel is connected to the pipeline for water supply, the filter screen on the second channel is replaced. When the filter screen on the first channel needs to be replaced, the positions of the first channel and the second channel are switched so that the second channel is connected to the pipeline for water supply, and the filter screen on the first channel can be replaced.

[0029] By using the first channel and the second channel, when the filter on the first channel needs to be replaced, the second channel is used to maintain communication with the pipeline, and water is supplied through the second pipeline. This allows the filter on the first channel to be replaced while the second channel is used to maintain communication with the pipeline for water supply. When the filter on the second channel needs to be replaced, the first channel is used to maintain communication with the pipeline for water supply. This allows the replacement of the filter and pipeline water supply to be carried out at the same time, which is beneficial to ensure that pipeline water use in civil or industrial fields is not affected; 2. The purpose of keeping the first rack and the second rack still during the rotation of the valve ball is: because the first rack and the second rack are installed inside the valve body, if the first rack and the second rack continue to rise during the rotation of the valve ball, once the valve ball has not rotated 90°, the first rack and the second rack have already abutted against the top of the valve body, that is, at this time, the first rack and the second rack can no longer continue to rise, but the valve ball has not rotated 90°, which makes the first rack and the second rack interfere with the rotation of the valve ball and affect the position of the valve ball rotation. Therefore, keeping the first rack and the second rack still during the rotation of the valve ball can effectively prevent the first rack and the second rack from interfering with the rotation of the valve ball; 3. The rubber ring is soft and elastic. When the second sealing plate extends into the valve ball through the slide groove, the rubber ring can adhere to the second sealing plate through its own elasticity, thereby effectively ensuring the stability of the second sealing plate after extending into the valve ball without causing damage to the second sealing plate.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1 -Attached Figure 5 , further details of this application are given.

[0033] Example: The present application discloses a filter ball valve that is convenient for replacing a filter element. Figure 1 and Figure 2, including a valve body in the shape of a rectangular parallelepiped as a whole, the valve body is composed of an upper shell 1 and a lower shell 2 distributed up and down, the upper shell 1 and the lower shell 2 are both hollow inside, and the two are connected up and down. A valve ball 3 is installed in the lower shell 2, and the valve ball 3 is respectively provided with a first channel 4 and a second channel 5, the first channel 4 and the second channel 5 both penetrate the valve ball 3, and the first channel 4 and the second channel 5 are in a "cross" structure as a whole, and the outer wall of the lower shell 2 is penetrated by a mounting hole 6 connected to these channels. The openings of the first channel 4 and the second channel 5 on the valve ball 3 are both in the same height as the mounting hole 6 on the outer wall of the lower shell 2. Two sets of sealing components are also added in the lower shell 2, and the two sets of sealing components are distributed on the left and right sides of the valve ball 3. The sealing component includes a first sealing plate 8 and a second sealing plate 9, both of which are vertically arranged, and both are slidably arranged in the lower shell 2 along the vertical direction. The first sealing plate 8 is located outside the valve ball 3, and the second sealing plate 9 is located above the side of the valve ball 3.

[0034] At the same time, a first driving assembly and a second driving assembly are additionally provided in the upper housing 1 .

[0035] Reference Figure 1 and Figure 2 The first driving assembly includes a first driving wheel 10 and a second driving wheel 11. The first driving wheel 10 is connected to the first sealing plate 8, and the second driving wheel 11 is connected to the second sealing plate 9. The first driving wheel 10 is used to drive the first sealing plate 8 to slide in the vertical direction, and the second driving wheel 11 is used to drive the second sealing plate 9 to slide in the vertical direction. The second driving assembly is used to drive the valve ball 3 to rotate in the horizontal direction in the lower housing 2.

[0036] When in use, the first channel 4 or the second channel 5 on the valve ball 3 is connected to the pipeline, and the water in the pipeline is supplied through the first channel 4 or the second channel 5. The openings of the first channel 4 and the second channel 5 are both equipped with a filter 7 for filtering the water in the pipeline, and the filter 7 is located between the corresponding first sealing plate 8 and the second sealing plate 9.

[0037] For ease of understanding, in this embodiment, the first channel 4 is connected to the pipeline as an example for description.

[0038] After the first channel 4 is connected to the pipeline, water is supplied. At this time, the second channel 5 is perpendicular to the direction of the first channel 4. In this state, the first sealing plate 8 is located outside the valve ball 3, and is located below the corresponding opening of the second channel 5, and is also located below the corresponding mounting hole 6. The bottom of the second sealing plate 9 extends into the interior of the valve ball 3 and seals the corresponding opening of the second channel 5. In this state, the filter screen 7 at the corresponding opening of the second channel 5 is located between the first sealing plate 8 and the second sealing plate 9, and the second channel 5 is sealed by the two second sealing plates 9 on both sides of the valve ball 3, thereby effectively preventing the water in the pipeline from leaking from the second channel 5.

[0039] After the two second sealing plates 9 seal the second channel 5, since the first sealing plate 8 is located below the corresponding mounting hole 6, the corresponding mounting hole 6 on the lower shell 2 is in an open state, and the filter screen 7 at the opening of the second channel 5 can be taken out through the mounting hole 6 on the outer wall of the lower shell 2 and replaced. When the filter screen 7 does not need to be replaced, the through hole on the outer wall of the lower shell 2 is sealed by the corresponding sealing plate.

[0040] With long-term use, when the filter screens 7 at the openings on both sides of the first channel 4 need to be replaced, the first driving wheel 10 and the second driving wheel 11 drive the first sealing plate 8 and the second sealing plate 9 on both sides of the valve ball 3 to rise until the first sealing plate 8 rises to the same height as the mounting hole 6 on the lower shell 2 and the second sealing plate 9 extends from the inside of the valve ball 3. In this state, the first sealing plate 8 seals the corresponding mounting hole 6 on the lower shell 2, and the second sealing plate 9 rises to the top of the valve ball 3 and disconnects from the valve ball 3. Then, the second driving assembly drives the valve ball 3 to rotate 90°, so that the first channel 4 and the second channel 5 switch positions. After the valve ball 3 rotates 90°, in this state, the second channel 5 remains connected to the pipeline, the second channel 5 is used for pipeline water supply, and the first pipeline and the second pipeline remain vertical.

[0041] When the first channel 4 and the second channel 5 have completed the position switching, the first driving wheel 10 and the second driving wheel 11 drive the corresponding first sealing plate 8 and the second sealing plate 9 to descend until the first sealing plate 8 descends to the bottom of the mounting hole 6 and the bottom of the second sealing plate 9 extends into the valve ball 3 to seal the first channel 4. In this state, the first sealing plate 8 descends to the bottom of the mounting hole 6 so that the position of the mounting hole 6 is reopened, and the two second sealing plates 9 seal the first channel 4, which can effectively prevent the water in the pipeline from leaking from the first channel 4. At this time, the filter screens 7 on both sides of the first pipeline can be taken out through the mounting hole 6 for replacement.

[0042] In summary, the function of the first sealing plate 8 is to seal or open the corresponding mounting hole 6, and the function of the second sealing plate 9 is to seal the first pipeline or the second pipeline.

[0043] In this setting method, by providing a first channel 4 and a second channel 5 on the valve ball 3, when the first channel 4 is connected to the pipeline for water supply, the filter screen 7 on the second channel 5 can be replaced. When the filter screen 7 on the first channel 4 needs to be replaced, the positions of the first channel 4 and the second channel 5 are switched so that the second channel 5 is connected to the pipeline for water supply, and the filter screen 7 on the first channel 4 can then be replaced.

[0044] By using the first channel 4 and the second channel 5, when the filter screen 7 on the first channel 4 needs to be replaced, the second channel 5 is kept connected to the pipeline, and water supply is carried out through the second pipeline. This enables the filter screen 7 on the first channel 4 to be replaced while maintaining water supply through the second channel 5 connected to the pipeline. When the filter screen 7 on the second channel 5 needs to be replaced, the first channel 4 is kept connected to the pipeline for water supply. Thus, the replacement of the filter screen 7 and the water supply to the pipeline can be carried out simultaneously, which is beneficial to ensuring that the pipeline water use in the civil or industrial fields is not affected.

The end of the fourth connecting rod 21 away from the second rack 19 is also connected to the second sealing plate 9 on the other side of the valve ball 3 through the third connecting rod 20.

[0048] When in use, the second rotating shaft 14 rotates while synchronously driving the second driving wheel 11 to rotate. The second driving wheel 11 engages with the second rack 19 during the rotation process, and drives the second rack 19 to lift and slide in the vertical direction. During the lifting and sliding process, the second rack 19 drives the second sealing plates 9 on both sides of the valve ball 3 to lift and slide in the vertical direction through the third connecting rod 20 and the fourth connecting rod 21.

The fourth bevel gear 28 is integrally sleeved on the second rotating shaft 14. The top of the third rotating shaft 29 is inserted into the third bevel gear 27, the third rotating shaft 29 is integrally connected with the third bevel gear 27, and the bottom of the third rotating shaft 29 is connected with the top of the valve ball 3.

[0051] In specific use, when the filter screen 7 on the first channel 4 needs to be replaced, the first driving wheel 10 and the second driving wheel 11 drive the corresponding first sealing plate 8 and the second sealing plate 9 to rise. When the first sealing plate 8 rises to the position of the corresponding mounting hole 6 and the second sealing plate 9 rises to above the valve ball 3, the driving motor 22 is turned on, and the driving motor 22 drives the screw 23 to rotate. The screw 23 is threadedly engaged with the lifting plate 24 during the rotation process to drive the lifting plate 24 to rise. While the lifting plate 24 rises, the lifting seat 25 and the rotating seat 26 are synchronously driven to rise until the third bevel gear 27 is meshed and connected with the fourth bevel gear 28. At this time, the second rotating shaft 14 is rotated to drive the fourth bevel gear 28 to rotate, and the third bevel gear 27 is driven to rotate through the fourth bevel gear 28. During the rotation of the third bevel gear 27, the third rotating shaft 29 is driven to rotate, and then the valve ball 3 is driven to rotate through the third rotation.

[0052] The fourth bevel gear 28 is initially positioned above the second rotating shaft 14. When the second rotating shaft 14 rotates to drive the first driving wheel 10 and the second driving wheel 11 to rotate, the fourth bevel gear 28 is synchronously driven to rotate. When the first rack 16 and the second rack 19 are raised and lowered to the specified positions, the fourth bevel gear 28 rotates to the bottom of the second rotating shaft 14, thereby enabling the third bevel gear 27 to rise and mesh with the fourth bevel gear 28.

[0053] When the valve ball 3 rotates 90° driven by the third rotating shaft 29 so that the first channel 4 and the second channel 5 switch positions, the driving motor 22 reverses to make the lifting plate 24 descend, and drives the third bevel gear 27 to descend through the lifting seat 25 and the rotating seat 26 until the third bevel gear 27 and the fourth bevel gear 28 are disengaged. In this state, the valve ball 3 no longer rotates. In this state, the first sealing plate 8 is located at the position of the corresponding mounting hole 6, and the second sealing plate 9 is located above the valve ball 3.

[0054] When the valve ball 3 is rotated, the first rotating shaft 12 and the second rotating shaft 14 are reversed, and the first driving wheel 10 and the second driving wheel 11 drive the corresponding first sealing plate 8 and the second sealing plate 9 to descend until the first sealing plate 8 is located below the corresponding mounting hole 6 and the bottom of the second sealing plate 9 extends into the valve ball 3 to seal the first channel 4. When the first sealing plate 8 and the second sealing plate 9 are lowered to the specified position, the filter screen 7 at the opening of the first pipeline can be taken out through the corresponding mounting hole 6 for replacement.

[0055] Furthermore, the teeth on the first driving wheel 10 and the second driving wheel 11 are each one quarter of the circumference thereof.

[0056] When the valve ball 3 needs to rotate, the third bevel gear 27 meshes with the fourth bevel gear 28 to drive the third rotating shaft 29 to rotate. The meshing of the third bevel gear 27 and the fourth bevel gear 28 is to drive the fourth bevel gear 28 to rotate through the rotation of the second rotating shaft 14. In this process, when the second rotating shaft 14 rotates, it will drive the first driving wheel 10 and the second driving wheel 11 to continue to rotate, and the first driving wheel 10 and the second driving wheel 11 will drive the corresponding first rack 16 and the second rack 19 to rise and fall during the rotation process. In order to prevent the first rack 16 and the second rack 19 from being displaced during the rotation of the valve ball 3, the teeth on the first drive wheel 10 and the second drive wheel 11 are set to one-fourth of their circumferences. The purpose of this is to effectively ensure that when the first rack 16 and the second rack 19 rise to the specified position, the teeth on the first drive wheel 10 and the second drive wheel 11 have reached the maximum engagement with the corresponding first rack 16 and the second rack 19. That is to say, when the first rack 16 and the second rack 19 rise to the specified position, even if the first drive wheel 10 and the second drive wheel 11 continue to rotate, they will not engage with the corresponding first rack 16 and the second rack 19. This effectively ensures that when the valve ball 3 needs to rotate, the second rotating shaft 14 rotates to drive the fourth bevel gear 28 and the third bevel gear 27 to engage. Although the first drive wheel 10 and the second drive wheel 11 also rotate together, the first drive wheel 10 and the second drive wheel 11 will not engage with the corresponding first rack 16 and second rack 19, thereby effectively ensuring that the first rack 16 and the second rack 19 will not be displaced during the rotation of the valve ball 3.

[0057] The purpose of keeping the first rack 16 and the second rack 19 still during the rotation of the valve ball 3 is that, because the first rack 16 and the second rack 19 are installed inside the valve body, if the first rack 16 and the second rack 19 continue to rise during the rotation of the valve ball 3, once the valve ball 3 has not rotated 90°, and the first rack 16 and the second rack 19 have abutted against the top of the valve body, that is, at this time, the first rack 16 and the second rack 19 can no longer continue to rise, but the valve ball 3 has not rotated 90°, which makes the first rack 16 and the second rack 19 interfere with the rotation of the valve ball 3 and affect the position of the rotation of the valve ball 3. Therefore, keeping the first rack 16 and the second rack 19 still during the rotation of the valve ball 3 can effectively prevent the first rack 16 and the second rack 19 from interfering with the rotation of the valve ball 3.

[0058] Specifically, refer to Figure 2 and Figure 3 A sliding groove 30 for the second sealing plate 9 to slide is formed through the top circumference of the valve ball 3 , and the second sealing plate 9 extends into the interior of the valve ball 3 through the corresponding sliding groove 30 .

[0059] Furthermore, a rubber ring is installed around the opening of the slide groove 30. The rubber ring is soft and elastic. When the second sealing plate 9 extends into the interior of the valve ball 3 through the slide groove 30, the rubber ring can adhere to the second sealing plate 9 through its own elasticity, thereby effectively ensuring the stability of the second sealing plate 9 after extending into the interior of the valve ball 3, and at the same time will not cause damage to the second sealing plate 9.

[0060] Further, refer to Figure 1 and Figure 2 A hand wheel 31 is installed at the end of the first rotating shaft 12. It is more convenient to rotate the first rotating shaft 12 by the hand wheel 31, and the experience is better.

[0061] Reference Figure 2 and Figure 5 In this embodiment, a sealing sheet 33 is hingedly installed inside the valve ball 3 at the opening of the chute 30, and the sealing sheet 33 is hingedly installed inside the valve ball 3 through a corresponding torsion spring. When the first channel 4 or the second channel 5 is in a water-passing state, the corresponding chute 30 at the top thereof is sealed by the sealing sheet 33 inside the valve ball 3, thereby effectively preventing the water inside the valve ball 3 from leaking from the chute 30. When the filter screen of the first channel 4 or the second channel 5 is replaced, the second sealing plate 9 presses the sealing sheet 33 downwards during the process of extending into the valve ball 3 through the corresponding chute 30, and the sealing sheet 33 rotates to open the chute 30, thereby allowing the second sealing plate 9 to smoothly enter the valve ball 3 to complete the sealing of the valve ball 3.

[0062] The implementation principle of a filter ball valve that is convenient for replacing a filter element in the embodiment of the present application is as follows: As the ball valve is used for a long time, when the filter screens 7 at the openings on both sides of the first channel 4 need to be replaced, the first driving wheel 10 and the second driving wheel 11 drive the first sealing plate 8 and the second sealing plate 9 on both sides of the valve ball 3 to rise until the first sealing plate 8 rises to the same height as the mounting hole 6 on the lower shell 2 and the second sealing plate 9 extends from the inside of the valve ball 3. In this state, the first sealing plate 8 seals the corresponding mounting hole 6 on the lower shell 2, and the second sealing plate 9 rises to the top of the valve ball 3 and disconnects from the valve ball 3. Then, the second driving assembly drives the valve ball 3 to rotate 90°, so that the first channel 4 and the second channel 5 switch positions. After the valve ball 3 rotates 90°, in this state, the second channel 5 remains connected to the pipeline, the second channel 5 is used for pipeline water supply, and the first pipeline and the second pipeline remain vertical.

[0063] When the first channel 4 and the second channel 5 have completed the position switching, the first driving wheel 10 and the second driving wheel 11 drive the corresponding first sealing plate 8 and the second sealing plate 9 to descend until the first sealing plate 8 descends to the bottom of the mounting hole 6 and the bottom of the second sealing plate 9 extends into the valve ball 3 to seal the first channel 4. In this state, the first sealing plate 8 descends to the bottom of the mounting hole 6 so that the position of the mounting hole 6 is reopened, and the two second sealing plates 9 seal the first channel 4, which can effectively prevent the water in the pipeline from leaking from the first channel 4. At this time, the filter screens 7 on both sides of the first pipeline can be taken out through the mounting hole 6 for replacement.

[0064] In summary, the function of the first sealing plate 8 is to seal or open the corresponding mounting hole 6, and the function of the second sealing plate 9 is to seal the first pipeline or the second pipeline.

[0065] This arrangement uses the first channel 4 and the second channel 5. When the filter screen 7 on the first channel 4 needs to be replaced, the second channel 5 is used to maintain communication with the pipeline, and water is supplied through the second pipeline. This allows the filter screen 7 on the first channel 4 to be replaced while the second channel 5 is used to maintain communication with the pipeline for water supply. When the filter screen 7 on the second channel 5 needs to be replaced, the first channel 4 is used to maintain communication with the pipeline for water supply. This allows the replacement of the filter screen 7 and pipeline water supply to be carried out simultaneously, which is beneficial to ensure that pipeline water use in the civil or industrial fields is not affected.

[0066] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
