Description

Technical Field

[0001] This application relates to the technical field of slurry valves, and in particular to a quick-release wear-resistant slurry valve core assembly. Background Technology

[0002] In industrial processes, the flow and control of various slurries such as mud, pulp, ceramics, and chemicals are of paramount importance to production efficiency and product quality. The Y-shaped slurry valve is one such example. The Y-shaped channel design reduces the viscous resistance of the medium and ensures stable flow.

[0003] When using slurry valves, disassembly, maintenance, and replacement are often required. However, most traditional slurry valves are fixed with many bolts when connected to the inlet and outlet pipes, which makes disassembly extremely time-consuming and laborious, and very inconvenient. Summary of the Invention

[0004] To facilitate maintenance of the slurry valve, this application provides a quick-release wear-resistant slurry valve core assembly.

[0005] This application provides a quick-release wear-resistant slurry valve core assembly, which adopts the following technical solution: A quick-release wear-resistant slurry valve core assembly includes a valve body, which is detachably connected to an inlet pipe and an outlet pipe via a connecting device, the connecting device comprising: Connecting pipe one and connecting pipe two are respectively installed on the feed pipe and the discharge pipe; The movable component rotates on the outer side wall of the second connecting pipe and can move along the axis of the second connecting pipe. A tapered connector is installed at one end of the valve body and inside the connecting pipe, and achieves positioning and sealing through tapered contact fit; A second tapered connector is disposed at the other end of the valve body and on the movable component, and extends into the second connecting pipe. It achieves positioning and sealing through tapered contact engagement. Both ends of the valve body are detachably connected to the first connecting pipe and the movable component via connecting assemblies. The valve body and the connecting pipe are made into conical contact through the first conical connector, and the valve body and the connecting pipe are positioned against each other. The valve body rotates and the valve body and the connecting pipe are connected through the connecting assembly. The moving part moves and the valve body and the connecting pipe are made into conical contact through the second conical connector, and the valve body and the connecting pipe are positioned against each other. The moving part rotates and the valve body and the connecting pipe are connected through the connecting assembly.

[0006] By adopting the above technical solution, the valve body is placed between the feed pipe and the discharge pipe. The conical connector on the valve body extends into the connecting pipe and forms a conical contact with the conical connector inside the connecting pipe, thereby achieving a positioning seal. At the same time, the valve body and the connecting pipe are positioned against each other. Rotating the valve body fixes the valve body and the connecting pipe to each other through the connecting assembly. The moving part moves closer to the valve body, causing the conical connector on the valve body and the moving part to abut against each other and form a conical contact, thereby achieving a positioning seal. At the same time, the moving part and the valve body abut against each other. Rotating the moving part fixes the moving part and the valve body to each other through the connecting assembly, thereby achieving a fixed connection between the valve body and the feed pipe and the discharge pipe.

[0007] Due to the conical design of conical connector one and conical connector two, the fluid flow will push conical connector one and conical connector two to move, causing the valve body to tend to move closer to the discharge pipe, thereby increasing the force between connecting block one and the snap-fit ​​groove, and further improving the stability and sealing effect of the valve body after connection.

[0008] During disassembly, rotating the moving part disengages it from the valve body, pushing it away from the valve body, and rotating the valve body disengages it from connecting pipe one. The valve body can then be moved and removed for replacement, thus improving the convenience of valve body maintenance. At the same time, the conical connecting parts one and two enable automatic positioning of the valve body during connection, further improving the convenience of valve body maintenance. Moreover, the connection between the valve body and connecting pipes one and two is located internally, thus improving the sealing effect after the valve body is connected.

[0009] Meanwhile, the movable part facilitates the tapered connection between the tapered connector 1 and the tapered connecting pipe 2 located inside the connecting pipe 1 and the connecting pipe 2. The connecting pipe 1 and the connecting pipe 2 are detachably connected to the feed pipe and the discharge pipe, respectively, thereby enabling the maintenance and replacement of the structure located on the connecting pipe 1 and the connecting pipe 2, which further improves the convenience of valve body connection and sealing effect.

[0010] Optionally, the tapered connector includes: A tapered component is disposed on one end of the valve body and communicates with the valve body to form a tapered contact surface. The second conical component is set on the inner wall of the first connecting pipe and is positioned in contact with the first mating surface, connecting the feed pipe, the first connecting pipe and the inside of the valve body.

[0011] By adopting the above technical solution, the second conical part approaches the first conical part, so that the second conical part abuts against the first contact surface to achieve conical contact. At the same time, the valve body abuts against the first connecting pipe, which can automatically align the valve body with the first connecting pipe, making it more convenient to connect through the connecting assembly later. Meanwhile, the second conical part connects the feed pipe, the first connecting pipe and the inside of the valve body, improving the convenience of valve body connection and sealing effect.

[0012] Optionally, the first conical part has a sealing groove, and a sealing ring is snapped onto the sealing groove to press against the second conical part for sealing.

[0013] By adopting the above technical solution, the sealing ring is pressed against the conical part 2 to achieve sealing, thereby further improving the sealing effect of the valve body.

[0014] Optionally, multiple connecting components are spaced apart, and each connecting component includes: Connecting block one and connecting block two are respectively set on valve body and connecting pipe one. Connecting block two has an arc-shaped snap-fit ​​groove. The rotation of valve body drives connecting block one to rotate and causes connecting block one to snap into the snap-fit ​​groove for positioning.

[0015] By adopting the above technical solution, the valve body is positioned against the connecting pipe 1, and then the valve body is rotated to drive the connecting block 1 to rotate and be snapped into the snap-fit ​​groove for positioning, thereby realizing the fixed connection between the feed pipe and the valve body. At the same time, when disassembling, the valve body can be removed by driving the valve body to rotate, which improves the convenience of valve body maintenance.

[0016] Optionally, a positioning groove communicating with the snap-fit ​​groove is provided on the second connecting block connected to the first connecting pipe and located on the side of the snap-fit ​​groove near the discharge pipe. A sealing ring is snapped onto the first connecting pipe and pressed against the valve body for positioning and sealing under the action of elasticity. The first connecting block is snapped onto the snap-fit ​​groove and moves to the positioning groove after being rotated into place. The first connecting block is pressed against the end of the positioning groove near the discharge pipe for positioning under the action of the elasticity of the sealing ring and the pushing action of the fluid in the valve body.

[0017] By adopting the above technical solution, when the valve body abuts against the connecting pipe, it compresses the sealing ring. Then, the valve body is rotated so that the connecting block is snapped into the snap-fit ​​groove. After the valve body is rotated into position, the elastic force of the sealing ring pushes the connecting block to move onto the positioning groove and towards the discharge pipe. This allows the connecting block to abut against the end of the positioning groove near the discharge pipe for positioning. At this time, the elastic force of the sealing ring and the movement of the fluid both push the valve body to maintain its tendency to approach the discharge pipe, thereby preventing the valve body from rotating and improving the positioning effect of the valve body. This further improves the stability and sealing effect of the valve body after connection. During disassembly, the valve body is pushed towards the feed pipe so that the connecting block moves onto the snap-fit ​​groove. After rotating the valve body, it can be removed, improving the convenience of valve body disassembly and assembly.

[0018] Optionally, a magnet is provided on the positioning groove, and the connecting block 1 is positioned by colliding and abutting against the magnet under the action of the sealing ring elasticity and the magnet adsorption force, and emits a prompt sound.

[0019] By adopting the above technical solution, the combination of the magnet block and the connecting block can better position the valve body, and the impact will produce a prompt sound, making the connection more convenient and the sealing effect better, thus improving the convenience of valve body maintenance and the sealing effect of the valve body.

[0020] Optionally, the second connecting block is fixedly installed on the first connecting pipe by screws, and the sealing ring is made of rubber and has an annular storage cavity inside.

[0021] By adopting the above technical solution, the second connecting block can be detachably set on the first connecting pipe, which facilitates the opening of the snap-fit ​​groove and the positioning groove and the installation of the magnet block, making the structure simpler and more stable; a storage cavity is provided inside the sealing ring, which makes the sealing ring easier to compress and easier to rebound after compression, thus improving the sealing effect.

[0022] Optionally, it also includes a positioning assembly for positioning the moving part and the valve body, the positioning assembly comprising: A positioning nut is installed on the moving part; The positioning rod has a threaded section. The positioning rod passes through the positioning nut, the moving part, the connecting pipe 2 and the valve body, and the threaded section is threadedly connected to the positioning nut for positioning.

[0023] By adopting the above technical solution, after the positioning rod is removed from the moving part, the moving part can rotate and move. After the moving part rotates into place, the positioning rod passes through the positioning nut, the moving part, and the connecting pipe and is then inserted into the valve body. During the insertion process, the threaded section is threaded into the positioning nut for positioning, thereby preventing the valve body and the moving part from rotating and thus unlocking. This improves the positioning effect of the positioning rod on the moving part and the valve body, and improves the stability and sealing effect of the valve body after installation.

[0024] Optionally, the second connecting pipe is provided with a limiting ring that limits the position of the moving part and allows the positioning rod to pass through, and the positioning nut is provided on the side wall of the moving part away from the valve body.

[0025] By adopting the above technical solution, the limiting ring setting creates a certain limit when the moving part moves, reducing the risk of the moving part moving too far. At the same time, the positioning rod passes through the limiting ring and is inserted into the valve body, so that neither the valve body nor the moving part can rotate. In addition, the limiting ring can also prevent the medium in the connecting pipe from flowing out, improving the convenience of valve body maintenance and sealing effect. Meanwhile, the positioning nut is located on the side of the moving part away from the valve body, so that the positioning nut will not interfere with the movement of the moving part and moves with the moving part. It also shortens the length of the positioning rod, making the structure simple and stable.

[0026] Optionally, a sealing element is snapped onto the limiting ring, which presses against the moving part under elastic force to provide support and sealing.

[0027] By adopting the above technical solution, the seal can buffer when the moving part comes into contact with the valve body, and at the same time, the seal can also achieve a seal, further improving the stability and sealing effect of the valve body.

[0028] In summary, this application includes at least one of the following beneficial technical effects: 1. The valve body is connected to the connecting pipes 1 and 2 in a conical shape by using conical connector 1 and conical connector 2, and the connection point is located inside the connecting pipes 1 and 2. At the same time, the valve body is fixedly connected to the connecting pipes 1 and 2 by rotating the valve body and the moving part, which improves the convenience of valve body maintenance and the sealing effect.

[0029] 2. When the valve body abuts against the connecting pipe, it compresses the sealing ring. Rotating the valve body causes the connecting block to snap into the snap-fit ​​groove. After the valve body is rotated into position, the elastic force of the sealing ring causes the connecting block to abut against the positioning groove near the discharge pipe for positioning. At this time, the elastic force of the sealing ring and the movement of the fluid will push the valve body to maintain its proximity to the discharge pipe, thereby preventing the valve body from rotating and improving the positioning effect of the valve body. This further improves the stability and sealing effect of the valve body after connection. For disassembly, push the valve body close to the feed pipe so that the connecting block moves into the snap-fit ​​groove. Then, rotate the valve body to remove it, improving the convenience of valve body disassembly and assembly. Attached Figure Description

[0032] The following provides a further detailed description of this application.

[0033] This application discloses a quick-release wear-resistant slurry valve core assembly.

[0034] Reference Figure 1 The quick-release wear-resistant slurry valve core assembly includes a valve body 1, which is detachably connected to the feed pipe 7 and the discharge pipe 8 via a connecting device 2.

[0035] Reference Figures 1-3 The connecting device 2 includes a first connecting pipe 21 and a second connecting pipe 22, a moving part 23, a first tapered connecting part 3, and a second tapered connecting part 4. The first connecting pipe 21 and the second connecting pipe 22 are fixedly installed on opposite ends of the feed pipe 7 and the discharge pipe 8 by flanges, screws, and nuts, respectively. The valve body 1 is located between the first connecting pipe 21 and the second connecting pipe 22. The first connecting pipe 21, the feed pipe 7, and the valve body 1 are coaxially arranged at one end, and the second feed pipe 7, the discharge pipe 8, and the valve body 1 are coaxially arranged at the other end. At the same time, rubber rings for sealing are provided between the first connecting pipe 21 and the feed pipe 7, and between the second connecting pipe 22 and the discharge pipe 8. The rubber rings are a common sealing structure and will not be described in detail here.

[0036] A limiting ring 24 is coaxially fixedly installed on the outer wall of the end of the connecting pipe 22 away from the discharge pipe 8. The moving part 23 is coaxially arranged with the connecting pipe 22. The moving part 23 is coaxially slidably installed on the outer wall of the connecting pipe 22 and can rotate relative to the connecting pipe 22. After passing around the limiting ring 24, the moving part 23 extends to the side of the connecting pipe 22 close to the connecting pipe 1 21. A ring-shaped moving cavity 25 is formed on the moving part 23 for the limiting ring 24 to move. At the same time, the moving part 23 is formed by fixing two parts with screws, thereby realizing the removal or installation of the moving part 23 from the connecting pipe 22.

[0037] Conical connector 3 and conical connector 4 are respectively disposed on the end of valve body 1 near connecting pipe 21 and connecting pipe 22. Conical connector 3 is also disposed on the inner wall of connecting pipe 21 and makes conical contact with the conical connector 3 on valve body 1, so that valve body 1 is positioned against the end of connecting pipe 21 near valve body 1 to achieve positioning and sealing. Conical connector 4 is also disposed on movable part 23 and extends to the inner wall of connecting pipe 22, and makes conical contact with the conical connector 4 on valve body 1, so that valve body 1 is positioned against the end of movable part 23 near valve body 1 to achieve positioning and sealing. Both ends of valve body 1 are detachably connected to connecting pipe 21 and movable part 23 through connecting assembly 5.

[0038] The valve body 1 and the connecting pipe 21 are made into conical contact through the conical connector 3, and the valve body 1 and the connecting pipe 21 are positioned against each other. The valve body 1 rotates and the valve body 1 and the connecting pipe 21 are connected through the connecting assembly 5. The moving part 23 moves and the valve body 1 and the connecting pipe 22 are made into conical contact through the conical connector 4, and the valve body 1 and the connecting pipe 22 are positioned against each other. The moving part 23 rotates and the valve body 1 and the connecting pipe 22 are connected through the connecting assembly 5.

[0039] The conical connector 3 includes a conical component 31 and a conical component 32. The conical component 31 is conical and coaxially fixedly installed on the inner wall of the valve body 1 near the end of the connecting pipe 21. One end of the conical component 31 extends to the outside of the valve body 1, and the interior of the conical component 31 communicates with the interior of the valve body 1. The conical component 32 is coaxially fixedly installed on the inner wall of the connecting pipe 21, and a conical mating surface 33 is formed on the inner wall of the conical component 32. The mating surface 33 is coaxially arranged with the connecting pipe 21. The conical component 31 is positioned by tightly abutting against the mating surface 33. At the same time, the valve body 1 is positioned by abutting against the end of the connecting pipe 21 near the valve body 1. The interior of the conical component 31 communicates with the feed pipe 7, the connecting pipe 21, and the interior of the valve body 1, thereby cooperating to position and seal the valve body 1.

[0040] The conical connector 4 includes a conical component 3 41 and a conical component 42. The conical component 3 41 is coaxially fixedly installed on the inner wall of the valve body 1 near the end of the connecting pipe 22. One end of the conical component 3 41 extends to the outside of the valve body 1, and the interior of the conical component 3 41 is connected to the interior of the valve body 1. The conical component 42 is coaxially fixedly installed on the end of the moving component 23 near the valve body 1 and extends into the connecting pipe 22. A conical mating surface 2 43 is formed on the inner wall of the conical component 42. The mating surface 2 43 is coaxially arranged with the connecting pipe 22. The conical component 3 41 is positioned by tightly abutting against the mating surface 2 43. At the same time, the valve body 1 is positioned by abutting against the end of the moving component 23 near the connecting pipe 21. The interior of the conical component 3 41 is connected to the discharge pipe 8, the connecting pipe 22, and the interior of the valve body 1, thereby cooperating to position and seal the valve body 1.

[0041] A sealing groove 34 is coaxially formed on the outer wall of the first tapered part 31 and the third tapered part 41. A sealing ring 35 is snapped onto the sealing groove 34 and presses against the first contact surface 33 and the second contact surface 43, thereby improving the sealing effect.

[0042] Reference Figures 1-5 The following explanation uses the connecting component 5, which is connected to the connecting pipe 21 and the valve body 1, as an example. Multiple connecting components 5 are arranged in a circumferential array around the axis of the connecting pipe 21. The connecting component 5 includes connecting block 51 and connecting block 52, which are both arc-shaped and coaxial with the connecting pipe 21. Connecting block 51 is fixedly installed on the outer wall of the valve body 1 near the connecting pipe 21. Connecting block 52 is fixedly installed on the end of the connecting pipe 21 near the valve body 1 by screws. Multiple connecting blocks 52 are located on the outside of the valve body 1. An arc-shaped snap-fit ​​groove 53 is opened on the side wall of the connecting block 52 near the axis of the connecting pipe 21. The snap-fit ​​groove 53 is opened around the axis of the connecting pipe 21 and one end passes through the connecting block 52.

[0043] Both the connecting pipe 21 and the moving part 23 have coaxial mounting grooves 26 on the side wall near the valve body 1. A sealing ring 27 is snapped onto the mounting groove 26 to press against the valve body 1 for sealing. The sealing ring 27 is made of rubber and has an annular storage cavity 28 inside. The storage cavity 28 can be filled with compressed air, which makes the sealing ring 27 easy to compress, improves the sealing effect, and the sealing ring 27 can quickly rebound after the extrusion pressure is lost.

[0044] Place the valve body 1 between the connecting pipe 21 and the moving part 23, push the conical part 31 against the mating surface 33, and after the valve body 1 squeezes the sealing ring 27, it abuts against the connecting pipe 21 for positioning, so that the connecting block 51 is located between two adjacent connecting blocks 52. Rotate the valve body 1 to drive the connecting block 51 to rotate at the same time, so that the connecting block 51 is snapped into the snap groove 53. Continue to rotate the valve body 1 until the connecting block 51 abuts against one end of the snap groove 53 for positioning.

[0045] The moving part 23 drives the conical part 42 to approach the conical part 3 41, so that the conical part 3 41 extends into the connecting pipe 22 and the conical part 3 41, and the conical part 3 41 abuts against the mating surface 2 43. After the valve body 1 squeezes the sealing ring 27, it abuts against the moving part 23 for positioning. Rotating the moving part 23 causes the connecting block 51 located at the end of the valve body 1 near the moving part 23 to snap into the snap groove 53 and abut against the end of the snap groove 53 for positioning, thereby realizing the fixed connection between the valve body 1 and the feed pipe 7 and the discharge pipe 8. The valve body 1 can be removed by reversing the operation.

[0046] The limiting ring 24 has a fixed groove 44 coaxially opened on the side wall away from the connecting pipe 21. A sealing element 45 is snapped onto the fixed groove 44. The sealing element 45 is made of alloy metal. When the moving part 23 pushes the conical part 3 41 against the mating surface 2 43, the sealing element 45 presses against the moving part 23 to seal.

[0047] A positioning groove 54 is provided on the connecting block 51 on the connecting pipe 21 along the axis of the connecting pipe 21. The positioning groove 54 is located on the side of the snap-fit ​​groove 53 near the connecting pipe 22 and the discharge pipe 8 and is connected to one end of the snap-fit ​​groove 53. The positioning groove 54 and the snap-fit ​​groove 53 have the same width. When the connecting block 51 abuts against one end of the snap-fit ​​groove 53, the connecting block 51 and the positioning groove 54 are aligned. Under the combined pushing action of the elasticity of the sealing ring 27 and the fluid in the valve body 1, the valve body 1 and the connecting block 51 move to the positioning groove 54, so that the connecting block 51 abuts against the end of the positioning groove 54 near the discharge pipe 8 and away from the feed pipe 7, so that the valve body 1 cannot rotate, further improving the stability of the valve body 1 after connection.

[0048] A magnet 55 is fixedly installed on one end of the positioning groove 54 near the discharge pipe 8. When the connecting block 51 is aligned with the positioning groove 54, the magnet 55 generates a certain attraction force on the connecting block 51, making it easier and faster for the connecting block 51 to enter the positioning groove 54. After impact, the connecting block 51 is attracted to the magnet 55 for positioning, and a clicking sound is emitted during the impact, making the connection of the valve body 1 more convenient and accurate. During disassembly, the valve body 1 is pushed to move the connecting block 51 back into the snap-fit ​​groove 53, and then the valve body 1 can be removed by rotating it, which improves the convenience of valve body 1 maintenance and sealing effect.

[0049] It also includes a positioning component 6 for positioning the moving part 23 and the valve body 1. The positioning component 6 includes a positioning nut 61 and a positioning rod 62. The positioning nut 61 is fixedly installed on the side wall of the moving part 23 away from the limiting ring 24 and the feed pipe 7. The moving part 23, the limiting ring 24, the connecting block 22 and the valve body 1 are all provided with through holes. When the valve body 1 is connected to the moving part 23, the through holes on the moving part 23, the limiting ring 24 and the connecting block 22 are aligned, or the through holes on the moving part 23, the limiting ring 24 and the valve body 1 are aligned. The positioning rod 62 can pass through the positioning nut 61 and multiple through holes, so that neither the moving part 23 nor the valve body 1 can rotate, thereby improving the stability of the valve body 1 after connection.

[0050] Meanwhile, the positioning rod 62 is provided with a threaded section. When the positioning rod 62 is inserted into multiple through holes for positioning, the threaded section is threadedly connected to the positioning nut 61 for positioning, thereby enabling the positioning rod 62 to be positioned and further improving the stability of the valve body 1 after connection. When movement is required, rotating the positioning rod 62 disengages the threaded section from the positioning nut 61, and then pulling the positioning rod 62 to disengage from the multiple through holes allows the moving part 23 to rotate and move.

[0051] The working principle of this application embodiment is as follows: Place the valve body 1 between the connecting pipe 21 and the moving part 23, push the conical part 31 against the mating surface 33, and after the valve body 1 squeezes the sealing ring 27, it abuts against the connecting pipe 21. Rotate the valve body 1 so that the connecting block 51 is snapped into the snap-fit ​​groove 53 and abuts against one end of the snap-fit ​​groove 53. The sealing ring 27 is pushed and the magnet 55 generates an adsorption force on the connecting block 51, so that the connecting block 51 is snapped into the positioning groove 54, and the connecting block 51 is adsorbed on the magnet 55 for positioning, so that the connecting pipe 21 and the valve body 1 are fixedly connected.

[0052] Pushing the moving part 23 causes the conical part 3 41 to abut against the mating surface 2 43, and the valve body 1 presses against the sealing ring 27 and abuts against the moving part 23. Rotating the moving part 23 causes the connecting block 51 located at the end of the valve body 1 near the moving part 23 to snap into the snap groove 53 and abut against the end of the snap groove 53 for positioning. The positioning rod 62 is inserted into multiple through holes, and the positioning rod 62 is screwed so that the threaded section is threaded into the positioning nut 61 for positioning. This achieves a fixed connection between the valve body 1 and the feed pipe 7 and the discharge pipe 8. The valve body 1 can be removed by reversing the operation, which improves the convenience of valve body 1 maintenance and the sealing effect of valve body 1.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
