Description

Technical Field

[0001] This invention relates to the field of ceramic valve technology, specifically to an impact-resistant ceramic valve and its method of use. Background Technology

[0002] Ceramic valves can greatly improve the smoothness and sealing of industrial pipeline systems and enhance the safety and stability of supporting equipment in harsh environments such as chemical, coal, and petroleum industries. They also play a positive role in promoting environmental protection and energy conservation. However, due to the nature of the materials used in ceramic valves, they are easily damaged by collisions during installation and transportation. Therefore, it is necessary to use a ceramic valve that can withstand impacts.

[0003] Existing impact-resistant ceramic valves are mainly designed to address the issue of collisions that occur during installation when external pipelines are inserted along the connecting pipes of the ceramic valve, due to docking and manual operation. These collisions can damage the internal structure of the ceramic valve. Therefore, anti-collision pads are installed at the internal connection points of the ceramic valve to reduce impact and prevent collision damage.

[0004] However, in actual use, the anti-collision pads only protect the end of the internal connecting pipe of the ceramic valve. Especially when the external connecting pipe comes into contact with the ceramic valve, it is easy to cause impact to its outer surface. However, the existing protection method is usually to set an anti-impact mechanism at its outer end. However, such protection method is difficult to position the external pipe well after docking, which reduces the effectiveness of the ceramic valve during installation. In view of this, we propose an impact-resistant ceramic valve and its usage method. Summary of the Invention

[0005] The purpose of this invention is to provide an impact-resistant ceramic valve and its method of use, so as to solve the problems mentioned in the background art.

[0007] A worm gear is rotatably mounted on the inner wall of the collar, a contact wheel passes through the worm gear and is fixedly connected to the worm gear, and a worm wheel is rotatably mounted on the inner wall of the collar.

[0008] The driving wheel is coaxially fixedly mounted on the worm gear, and the driving wheel is connected to the driven wheel through a transmission belt.

[0009] An adjusting screw is provided. The end of the adjusting screw is rotatably mounted on the inner wall of the collar. A threaded sleeve is threadedly connected to the outer wall of the adjusting screw. The end of a telescopic column is fixedly connected to the side wall of the threaded sleeve. A connecting plate is fixedly connected to the other end of the telescopic column. The end of a protective spring is fixedly connected to the side wall of the threaded sleeve. The other end of the protective spring is fixedly connected to the side wall of the connecting plate. The end of a rotating rod is rotatably mounted on the other outer wall of the connecting plate.

[0010] Preferably, a strip-shaped limiting block is provided on the arc-shaped outer wall of the protective tube, and a circular hole adapted to the outer diameter of the protective tube is opened inside the collar. The protective tube is slidably installed in the circular hole, and a limiting groove adapted to the strip-shaped limiting block is opened on the inner surface of the circular hole. This allows the protective tube and the collar to slide only in the horizontal direction, and there will be no relative rotation between them.

[0011] Preferably, the collar has a rectangular groove with a width that matches the width of the contact wheel on the side near the internal cavity. Specifically, the contact wheel is disposed inside the rectangular groove, and the bottom end of the contact wheel extends out of the bottom end of the rectangular groove, so that the contact wheel can better contact the arc-shaped outer wall of the protective tube.

[0012] Preferably, the telescopic column is hollow inside, and the diameter of the internal cavity of the telescopic column is larger than the outer diameter of the adjusting screw, so that the telescopic column will not interfere with the rotation of the adjusting screw.

[0013] Preferably, a relief assembly is provided on the outer wall of the rotating rod, the relief assembly includes a transmission wheel, a rotating hole is opened on the side wall of the collar, and a protrusion is fixedly installed on the inner surface of the rotating hole.

[0014] Preferably, the outer arc-shaped wall of the rotating rod is provided with a spiral groove, and the spiral groove matches the protrusion, so that when the rotating rod moves horizontally along the rotating hole, the rotating rod will continuously rotate on the side wall of the connecting plate.

[0015] Preferably, the outer wall of the protective plate near the collar has an annular transmission groove adapted to the transmission wheel, and the arc-shaped outer wall of the transmission wheel abuts against the inner surface of the annular transmission groove, so that when the rotating rod drives the transmission wheel to rotate, it can drive the protective plate to rotate.

[0016] Preferably, an auxiliary positioning component is provided at the temporal portion of the connecting tube. The auxiliary positioning component includes a transmission rod, which is rotatably mounted on the inner wall of the connecting tube. A reduction wheel passes through the transmission rod and is fixedly connected to the reduction wheel. The end of a spiral spring is fixedly connected to the side wall of the reduction wheel, and the other end of the spiral spring is fixedly connected to the inner wall of the connecting tube. The bottom end of a telescopic rod is fixedly connected to the inner wall of the reduction wheel, and a slider is fixedly connected to the top end of the telescopic rod.

[0017] Preferably, the side of the fork-shaped deceleration bar away from the slider is configured as an arc shape that matches the arc-shaped inner surface of the connecting pipe, so that the fork-shaped deceleration bar can more stably clamp and position the external pipeline.

[0018] A method for using an impact-resistant ceramic valve includes the following steps:

[0019] S1. Insert the external tubing into the internal cavity of the protective sheet;

[0020] S2. The external pipeline enters the interior of the connecting pipe after passing through the protective pipe;

[0021] S3. After it is fully inserted, the external pipe connection part pushes the transmission plate until the transmission plate and the collar are pressed together, thus completing the insertion of the external pipe.

[0022] S4. Secure the external pipeline and valve body with locking bolts to complete the connection and installation of the ceramic valve with the external pipeline.

[0023] Compared with the prior art, the present invention provides an impact-resistant ceramic valve and its method of use, which has the following beneficial effects:

[0024] 1. This impact-resistant ceramic valve and its usage method: To avoid excessive elasticity during the installation of the ceramic valve and causing interference to subsequent installations, an anti-impact component is incorporated. This component, in conjunction with the contact wheel and the protective tube, and the transmission structure within the collar, allows the adjusting screw to adjust the spring force of the protective spring in a timely manner as the protective tube moves. Specifically, this ensures that the protective spring, while consistently protecting the protective plate and the protective tube, does not excessively compress the protective plate, thus avoiding interference with the final connection and positioning of the external pipeline and affecting the stable installation of the valve body.

[0025] 2. The impact-resistant ceramic valve and its usage method: In order to better avoid the impact on the ceramic valve when external pipes that need to be connected are inserted without proper alignment, a mitigation component is set up, which, together with the protrusions and the spiral groove opened on the arc-shaped outer wall of the rotating rod, causes the protective plate to rotate when it is impacted, in conjunction with the transmission wheel. This changes the linear impact force toward the valve body into the movement of the rotating protective plate, reducing the impact on the valve body and ensuring the safe use of the ceramic valve.

[0026] 3. The impact-resistant ceramic valve and its usage method are designed to prevent damage to the durability of the ceramic valve caused by the friction and scratching between the external pipeline and the inner wall of the connecting pipe when the external pipeline is inserted into the connecting pipe during pipeline assembly. An auxiliary positioning component is provided, which works in conjunction with a clamping spring and a fork-shaped deceleration bar that is adapted to the inner surface of the connecting pipe, to clamp and position the external pipeline when it is inserted into the connecting pipe.

[0035] like Figure 1-7 As shown, the present invention provides a technical solution: an impact-resistant ceramic valve and its usage method, comprising a valve body 1, a valve cylinder 2 fixedly mounted on the top of the valve body 1, a connecting pipe 3 fixedly connected to the end of the side wall of the valve body 1, a collar 4 fixedly connected to the other end of the connecting pipe 3, a protective pipe 5 slidably connected to the inner surface of the collar 4, a protective plate 6 rotatably connected to the end of the protective pipe 5, an anti-impact component provided inside the collar 4, the anti-impact component including a worm gear 7, the worm gear 7 rotatably mounted on the inner wall of the collar 4, the worm gear 7 passing through a contact wheel 8, and the contact wheel 8 being fixedly connected to the worm gear 7, the inner wall of the collar 4 being rotatably mounted The device is equipped with a worm gear 9, and a driving wheel 10 is coaxially fixedly mounted on the worm gear 9. The driving wheel 10 is connected to the driven wheel 12 via a transmission belt 11. The end of an adjusting screw 13 is rotatably mounted on the inner wall of the collar 4. A threaded sleeve 14 is threadedly connected to the outer wall of the adjusting screw 13. The end of a telescopic column 15 is fixedly connected to the side wall of the threaded sleeve 14. A connecting plate 16 is fixedly connected to the other end of the telescopic column 15. The end of a protective spring 17 is fixedly connected to the side wall of the threaded sleeve 14. The other end of the protective spring 17 is fixedly connected to the side wall of the connecting plate 16. The end of a rotating rod 18 is rotatably mounted on the other outer wall of the connecting plate 16.

[0036] In one embodiment of the present invention, the valve cylinder 2 is a pneumatic cylinder to control the opening and closing of the ceramic valve. Two sets of connecting pipes 3 are provided, with the two sets of connecting pipes 3 respectively located on the left and right sides of the valve body 1. Furthermore, the internal cavity diameter of the protective pipe 5 is matched with the internal cavity diameter of the connecting pipe 3, allowing external pipes to pass through the protective pipe 5 and then be inserted into the internal space of the connecting pipe 3. This ensures that the external pipes can be stably installed inside the connecting pipe 3 and the protective pipe 5. Additionally, a strip-shaped limiting block is provided on the arc-shaped outer wall of the protective pipe 5, and a sleeve... The ring 4 has a circular hole inside that matches the outer diameter of the protective tube 5, and the protective tube 5 is slidably installed in the circular hole. The inner surface of the circular hole has a limiting groove that matches the strip-shaped limiting block, so that the protective tube 5 and the collar 4 can only slide in the horizontal direction and there will be no relative rotation between them. Furthermore, the protective plate 6 has a circular hole inside that matches the internal cavity of the protective tube 5, so that the external pipeline can be inserted into the interior of the protective plate 6 first, and then installed through the protective tube 5 and the connecting pipe 3.

[0037] In an embodiment of the present invention, two sets of anti-impact components are provided, and the two sets of anti-impact components are symmetrically arranged in the internal spaces of the upper and lower sides of the collar 4 with the central axis of the collar 4 as the axis of symmetry. At the same time, the worm gear 9 meshes with the worm 7 to achieve transmission. The collar 4 has a rectangular groove with a width adapted to the width of the contact wheel 8 on the side near the internal cavity. Specifically, the contact wheel 8 is disposed inside the rectangular groove, and the bottom end of the contact wheel 8 extends out of the bottom end of the rectangular groove, so that the contact wheel 8 can better contact the arc-shaped outer wall of the protective tube 5 and pass through the protective tube. The movement of wheel 5 causes contact wheel 8 to rotate. Specifically, the rotation of contact wheel 8, in conjunction with worm gear 7, drives worm wheel 9 to rotate. This rotation, through drive wheel 10 and transmission belt 11, drives driven wheel 12 to rotate. Furthermore, adjusting screw 13 passes through driven wheel 12, and driven wheel 12 is fixedly connected to adjusting screw 13. This allows adjusting screw 13 to rotate when driven wheel 12 rotates. Simultaneously, the top outer wall of threaded sleeve 14 is slidably connected to the inner wall of collar 4, thereby guiding the movement direction of threaded sleeve 14. Specifically, when the adjusting screw 13 rotates, the threaded sleeve 14 can only slide horizontally along the inner wall of the collar 4, and cannot rotate with the adjusting screw 13. Furthermore, the protective spring 17 is sleeved on the arc-shaped outer wall of the telescopic column 15, ensuring that the protective spring 17 maintains its horizontal deformation direction only when compressed or stretched, and does not exhibit vertical deflection due to its own weight or compression. This ensures that the protective spring 17 always provides a stable transmission effect for the connecting plate 16. At the same time, the connecting plate 16 is also slidably connected to the inner wall of the collar 4 to ensure the stable transmission effect of the connecting plate 16 on the rotating rod 18. Furthermore, the telescopic column 15 is hollow inside, and the diameter of the internal cavity of the telescopic column 15 is larger than the outer diameter of the adjusting screw 13, so that the telescopic column 15 will not interfere with the rotation of the adjusting screw 13. Similarly, the rotating rod 18 has a circular hole with a diameter larger than the outer diameter of the adjusting screw 13 inside, so that when the rotating rod 18 moves, it will not interfere with the rotation of the adjusting screw 13, thereby ensuring the stable use of the adjusting screw 13.

[0038] In addition, in order to better avoid the impact on the ceramic valve when the external pipes that need to be connected are inserted without proper alignment, a relief component is provided on the outer wall of the rotating rod 18. The relief component includes a transmission wheel 19, and a rotating hole is opened on the side wall of the collar 4. A protrusion 20 is fixedly installed on the inner surface of the rotating hole.

[0039] In an embodiment of the present invention, the outer diameter of the rotating rod 18 is adapted to the inner diameter of the rotating hole, and a spiral groove is provided on the arc-shaped outer wall of the rotating rod 18, and the spiral groove matches the protrusion 20. Specifically, when the connecting plate 16 moves horizontally along the inner wall of the collar 4, it drives the rotating rod 18 to move horizontally along the inner wall of the rotating hole. Due to the arrangement of the protrusion 20 and the spiral groove, when the rotating rod 18 moves horizontally along the rotating hole, the rotating rod 18 will continuously rotate on the side wall of the connecting plate 16. Furthermore, an annular transmission groove adapted to the transmission wheel 19 is provided on the outer wall of the protective plate 6 near the collar 4, and the arc-shaped outer wall of the transmission wheel 19 abuts against the inner surface of the annular transmission groove, so that when the rotating rod 18 drives the transmission wheel 19 to rotate, it can drive the protective plate 6 to rotate.

[0040] In addition, to prevent damage to the durability of the ceramic valve caused by the friction between the external pipes inserted into the inner wall of the connecting pipe 3 during pipe assembly, an auxiliary positioning component is provided at the temporal part of the connecting pipe 3. The auxiliary positioning component includes a transmission rod 21, which is rotatably mounted on the inner wall of the connecting pipe 3. The transmission rod 21 passes through a reduction wheel 22, and the reduction wheel 22 is fixedly connected to the transmission rod 21. The end of a spiral spring 23 is fixedly connected to the side wall of the reduction wheel 22, and the other end of the spiral spring 23 is fixedly connected to the inner wall of the connecting pipe 3. The bottom end of a telescopic rod 24 is fixedly connected to the inner wall of the reduction wheel 22, and a slider 25 is fixedly connected to the top end of the telescopic rod 24. A fork-shaped deceleration strip 26 is fixedly installed on the top of the slider 25. The bottom end of a retaining spring 27 is fixedly connected to the inner wall of the reduction wheel 22, and the top end of the retaining spring 27 is fixedly connected to the lower surface of the slider 25.

[0041] In an embodiment of the present invention, three sets of auxiliary positioning components are provided, and the three sets of auxiliary positioning components are evenly distributed in a circumferential array on the arc-shaped inner surface of the connecting pipe 3. Specifically, a placement groove for placing the spiral spring 23 is provided on the side wall of the reduction wheel 22, so that the spiral spring 23 can always provide a stable transmission effect for the reduction wheel 22 without affecting the installation of the reduction wheel 22. At the same time, the telescopic rod 24, the slider 25, the fork-shaped deceleration bar 26, and the clamping spring 27 are all provided on the arc-shaped outer wall of the reduction wheel 22. Specifically, the side of the fork-shaped deceleration bar 26 away from the slider 25 is arranged to be connected to the connecting pipe. The arc shape of the inner surface of the connecting pipe 3 is adapted to the arc shape, so that the fork-shaped deceleration strip 26 can more stably clamp and position the external pipeline. Furthermore, the arc-shaped outer wall of the deceleration wheel 22 is provided with a groove adapted to the slider 25, so that under the elastic force of the clamping spring 27, the slider 25 can better drive the fork-shaped deceleration strip 26 to clamp and position the external pipeline. Specifically, in the initial state, the slider 25 drives the fork-shaped deceleration strip 26 without exceeding the internal cavity of the connecting pipe 3 by too much distance, thereby avoiding jamming and blockage of the external pipeline, so as to facilitate the installation and erection of the external pipeline and the valve body 1.

[0042] In this invention, during use, the external pipe is first inserted into the inner cavity of the protective plate 6, and then enters the connecting pipe 3 through the protective tube 5. At this time, the arc-shaped outer wall of the external pipe contacts the lower surface of the fork-shaped deceleration bar 26. This, combined with the transmission rod 21, causes the deceleration wheel 22 to rotate without interfering with the advancement of the external pipe. Under the elastic force of the spiral spring 23, the external pipe is positioned more tightly. When fully inserted, the connecting part of the external pipe contacts the protective plate 6 first and pushes the protective plate 6 to the left, causing the protective tube 5 to move to the left. This causes the contact wheel 8 to start rotating. Combined with the transmission of the worm gear 9 and worm 7, and the transmission of the driving wheel 10, transmission belt 11, and driven wheel 12, the adjusting screw 13 rotates accordingly, thereby cooperating with the screw... The sleeve 14 and the connecting plate 16 are used to adjust the elastic force of the protective spring 17 as needed. Specifically, this ensures that the protective spring 17, while always providing protection for the protective plate 6 and the protective tube 5, does not excessively compress the protective plate 6, thus avoiding interference with the final docking and positioning of the external pipeline and affecting the stable installation of the valve body 1. In addition, to better prevent the impact on the ceramic valve when the external pipeline to be docked is inserted without proper alignment, a mitigation component is provided. This component, along with the protrusion 20 and the spiral groove on the arc-shaped outer wall of the rotating rod 18, allows the protective plate 6 to rotate when it is impacted, in conjunction with the transmission wheel 19. This transforms the linear impact force towards the valve body 1 into the rotational movement of the protective plate 6, reducing the impact on the valve body 1 and ensuring the safe use of the ceramic valve.

[0043] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
