Description

Technical Field

[0001] This utility model belongs to the field of valve technology, and in particular relates to a valve suitable for fluid media containing large particles. Background Technology

[0002] In industrial fields such as mining, construction, and metallurgy, valves are key equipment in the transportation and control of fluid media containing large particles. Their performance directly affects the stable operation of the production system. Valves are pipeline accessories used to open and close pipelines, control the flow direction, and regulate and control the parameters of the transported medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc.

[0003] In actual production, the particle size of the conveyed materials varies greatly under different working conditions. For example, in the mineral processing of mines, the slurry particles are large in the coarse crushing stage and small in the fine crushing stage. Traditional valves cannot clearly display the opening and closing degree, making it difficult for operators to adjust the valve opening and closing degree in a timely and accurate manner according to the changes in the particle size of the material. They can only make rough adjustments based on experience. This method is not only inefficient, but also prone to over-adjustment or under-adjustment. Over-adjustment may cause large particles to flow too fast, causing more serious wear on the internal components of the valve. Under-adjustment will cause pipeline blockage, affecting production efficiency. As large particles flow with the fluid, they exert strong scouring and impact on the valve seat, valve core and other components inside the valve, causing rapid wear on the surface of the components, reduced sealing performance and causing media leakage.

[0004] To address these issues, we provide a valve suitable for fluid media containing large particles. Utility Model Content

[0005] The purpose of this invention is to provide a valve suitable for fluid media containing large particles. By combining the opening and closing indicator component and the valve component, it solves the problem in the prior art where the valve cannot clearly display the opening and closing degree, making it difficult for operators to adjust the valve opening and closing degree according to changes in the particle size of the material, and the resulting wear reduces the service life of the valve.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a valve suitable for fluid media containing large particles, comprising an electric actuator. An opening / closing indicator assembly is fixedly connected to the bottom of the electric actuator, and a valve assembly is fixedly connected to the bottom of the opening / closing indicator assembly. The opening / closing indicator assembly includes a mounting cover, the top of which is fixedly connected to the electric actuator. A connecting column is fixedly connected to the bottom of the electric actuator, with the bottom of the connecting column extending into the inner cavity of the mounting cover. A connecting block is fixedly connected to the bottom of the connecting column, and an indicator is fixedly connected to one side of the bottom of the connecting block. A reference table is fixedly connected to one side of the inner wall of the mounting cover. A valve stem is fixedly connected to the bottom of the connecting block. The bottom of the connecting column extends through a pre-drilled hole at the top of the mounting cover into the inner cavity of the mounting cover. The connecting block serves as an intermediate connector between the connecting column, valve stem, and indicator, providing a stable mounting foundation. The reference table clearly indicates the corresponding valve opening / closing degrees. The indicator position markings and the design of the opening / closing indicator components allow for a clear and intuitive display of the valve's opening and closing status and degree of opening. When the electric actuator operates, it drives the connecting column to move up and down, which in turn drives the connecting block to move synchronously. The indicator on the connecting block also moves within the mounting cover. By observing the corresponding position of the indicator on the reference table, the operator can clearly and accurately determine the current opening and closing degree of the valve. This intuitive indication method avoids the hassle of the operator having to approach the valve or perform complex operations to determine its status. It is particularly suitable for valves widely distributed in large industrial pipeline systems, greatly improving operational convenience and work efficiency. At the same time, when handling materials of different particle sizes, the operator can quickly adjust the valve opening degree based on the opening and closing degree displayed by the indicator, adapting the fluid flow rate to the material characteristics, reducing wear on valve components caused by improper flow rate, and ensuring stable operation of the equipment.

[0008] The present invention is further configured such that the valve assembly includes a valve cover, the top of which is fixedly connected to a mounting cover, the bottom of which is fixedly connected to a valve body, and the inner cavity of the valve body is fixedly connected to a valve seat. The bottom of the valve stem penetrates the top of the valve cover and extends to the inner cavity of the valve seat, and the bottom of the valve stem is fixedly connected to a closing mechanism. The top of the valve cover is fixedly connected to the mounting cover, and the bottom is fixed to the valve body, forming a stable connection structure. This provides a reliable support frame for the valve assembly, ensuring that the valve components are not prone to loosening under high-pressure impact from fluid media containing large particles. The valve seat fixed in the inner cavity of the valve body, together with the valve cover and valve body, forms a stable fluid channel, enabling large particles of fluid to flow stably within the valve body, reducing fluid turbulence caused by component shaking, and reducing abnormal wear of particles on the inner wall of the valve.

[0009] The present invention is further configured such that the closing mechanism includes a connecting seat, the top of the connecting seat is fixedly connected to the valve stem, the bottom of the connecting seat is fixedly connected to the valve core, and the bottom of the valve core is fixedly connected to a sealing gasket. The connecting seat serves as a connector between the valve stem and the valve core, ensuring that the valve core can move accurately with the movement of the valve stem. The sealing gasket is made of a highly elastic and wear-resistant material, which can effectively resist the impact and wear of large particles on the sealing surface. At the same time, under the action of fluid pressure, it further enhances the sealing effect and prevents leakage of fluid media containing large particles.

[0010] The present invention is further configured such that a packing gland is provided at the bottom of the inner cavity of the mounting cover, and a packing assembly is filled between the valve stem and the valve cover. The packing gland and the packing assembly filled between the valve stem and the valve cover cooperate with each other to form an effective sealing barrier. The packing assembly can tightly fill the gap between the valve stem and the valve cover, preventing fluid media containing large particles from leaking from the gap. By applying pressure, the packing gland can further compact the packing assembly and enhance the sealing effect.

[0011] The present invention is further configured such that the top of the valve seat contacts the valve cover, the bottom of the valve seat contacts the valve body, and a sealing ring is provided at both the top and bottom of the valve seat. The sealing ring is in close contact with the valve cover and the valve body respectively, forming a double sealing structure. The sealing ring is made of wear-resistant rubber material, which is deformed by compression during valve assembly, and can fully fill the tiny gaps between the valve seat, the valve cover, and the valve body, effectively preventing the leakage of fluid media containing large particles from the connection parts.

[0012] The present invention is further configured such that a nut is provided on the top of the valve stem surface, and the top of the valve stem is fixedly connected to the connecting block by the nut. The fixed connection between the top of the valve stem and the connecting block by the nut provides a stable fixing method for the valve stem, ensuring that the power of the electric actuator can be stably transmitted to the valve stem.

[0013] The present invention is further configured such that a first flange is connected to one side of the valve body and a second flange is connected to the other side of the valve body, and the first flange and the second flange facilitate the connection and disassembly of the valve to the pipeline system.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model uses an electric actuator to drive the connecting column and connecting block to move, so that the indicator matches the reference table on the inner wall of the mounting cover. The operator can obtain the valve opening and closing information in real time, intuitively and accurately. When processing materials of different particle sizes, the valve opening and closing degree can be quickly and accurately adjusted according to the actual working conditions. In different stages of mineral processing, the valve opening and closing degree can be adjusted to a suitable value according to the particle size of the slurry, avoiding excessive wear of parts or blockage of pipelines due to improper flow rate, and effectively improving production efficiency and equipment stability.

[0016] 2. This utility model forms a multi-layer sealing and protective structure by tightly fitting the sealing gasket at the bottom of the valve core with the valve seat, combined with the sealing rings at the top and bottom of the valve seat, as well as the packing assembly and packing gland between the valve stem and the valve cover. This greatly enhances the valve's sealing performance, effectively resists the impact and wear of large particles on the sealing surface, prevents media leakage, improves the overall impact resistance and stability of the valve, significantly extends the valve's service life, and meets the stringent requirements for high sealing of valves in fluid media containing large particles.

[0026] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0027] Please see Figure 1-7 This utility model is a valve suitable for fluid media containing large particles, including an electric actuator 1, an opening / closing indicator assembly 2 fixedly connected to the bottom of the electric actuator 1, a valve assembly 3 fixedly connected to the bottom of the opening / closing indicator assembly 2, the opening / closing indicator assembly 2 including a mounting cover 21, the top of the mounting cover 21 fixedly connected to the electric actuator 1, a connecting column 22 fixedly connected to the bottom of the electric actuator 1, the bottom of the connecting column 22 penetrating into the inner cavity of the mounting cover 21, a connecting block 23 fixedly connected to the bottom of the connecting column 22, an indicator 24 fixedly connected to one side of the bottom of the connecting block 23, a reference table 25 fixedly connected to one side of the inner wall of the mounting cover 21, and a valve stem 26 fixedly connected to the bottom of the connecting block 23.

[0028] Specifically: The bottom of the connecting column 22 penetrates the pre-drilled hole at the top of the mounting cover 21 and extends into the inner cavity of the mounting cover 21. The connecting block 23 serves as the intermediate connector between the connecting column 22, the valve stem 26, and the indicator 24, providing a stable mounting base. The reference table 25 clearly marks the position of the indicator 24 corresponding to different valve opening degrees. The design of the opening and closing indicator component 2 allows the valve's opening and closing status and degree to be displayed intuitively. When the electric actuator 1 works, it drives the connecting column 22 to move up and down. The connecting column 22 drives the connecting block 23 to move synchronously, and the indicator 24 on the connecting block 23 also moves within the mounting cover 21 accordingly. By observing the corresponding position of indicator 24 on the reference table 25, operators can clearly and accurately know the current opening degree of the valve. This intuitive indication method avoids the trouble of operators having to approach the valve or perform complex operations to judge the valve status. It is especially suitable for valves that are widely distributed in large industrial pipeline systems, greatly improving the convenience of operation and work efficiency. At the same time, when handling materials with different particle sizes, operators can quickly adjust the valve opening according to the opening degree displayed by indicator 24, so that the fluid flow rate is adapted to the material characteristics, reducing the wear of valve components caused by improper flow rate, and ensuring the stable operation of the equipment. Example

[0029] Please see Figure 1-7Based on Embodiment 1, the valve assembly 3 includes a valve cover 31, the top of which is fixedly connected to the mounting cover 21. A valve body 32 is fixedly connected to the bottom of the valve cover 31. A valve seat 33 is fixedly connected to the inner cavity of the valve body 32. The bottom of the valve stem 26 penetrates the top of the valve cover 31 and extends into the inner cavity of the valve seat 33. A closing mechanism 34 is fixedly connected to the bottom of the valve stem 26. The closing mechanism 34 includes a connecting seat 341, the top of which is fixedly connected to the valve stem 26. A valve core 342 is fixedly connected to the bottom of the connecting seat 341. A sealing gasket 343 is fixedly connected to the bottom of valve 342. A packing gland 4 is provided at the bottom of the inner cavity of the mounting cover 21. A packing assembly 5 is filled between the valve stem 26 and the valve cover 31. The top of the valve seat 33 contacts the valve cover 31, and the bottom of the valve seat 33 contacts the valve body 32. A sealing ring 6 is provided at both the top and bottom of the valve seat 33. A nut 7 is provided at the top of the surface of the valve stem 26. The top of the valve stem 26 is fixedly connected to the connecting block 23 through the nut 7. A first flange 8 is connected to one side of the valve body 32, and a second flange 9 is connected to the other side of the valve body 32.

[0030] Specifically: The top of the valve cover 31 is fixedly connected to the mounting cover 21, and the bottom is fixed to the valve body 32, forming a stable connection structure. This provides a reliable support frame for the valve assembly 3, ensuring that the valve components are not prone to loosening under high-pressure impact from fluid media containing large particles. The valve seat 33, fixed inside the valve body 32, together with the valve cover 31 and the valve body 32, forms a stable fluid channel, allowing large particles of fluid to flow stably within the valve body 32, reducing fluid turbulence caused by component shaking, and reducing abnormal wear of particles on the valve's inner wall. The connecting seat 341 serves as the connection between the valve stem 26 and the valve core 342, ensuring that the valve core 342 can move accurately with the movement of the valve stem 26. The sealing gasket 343 is made of highly elastic and wear-resistant material, which can effectively resist the impact and wear of large particles on the sealing surface. At the same time, under fluid pressure, it further enhances the sealing effect and prevents leakage of fluid media containing large particles. The packing gland 4 and the valve stem 26... The packing assembly 5 between the valve stem 26 and the valve cover 31 works together to form an effective sealing barrier. The packing assembly 5 can tightly fill the gap between the valve stem 26 and the valve cover 31, preventing the leakage of fluid media containing large particles from the gap. The packing gland 4 can further compact the packing assembly 5 by applying pressure, enhancing the sealing effect. The sealing ring 6 is in close contact with the valve cover 31 and the valve body 32 respectively, forming a double sealing structure. The sealing ring 6 is made of wear-resistant rubber material. When the valve is assembled, it is squeezed and deformed, which can fully fill the small gaps between the valve seat 33 and the valve cover 31 and the valve body 32, effectively preventing the leakage of fluid media containing large particles from the connection. The top of the valve stem 26 is fixedly connected to the connecting block 23 by the nut 7, providing a stable fixing method for the valve stem 26 and ensuring that the power of the electric actuator 1 can be stably transmitted to the valve stem 26. The first flange 8 and the second flange 9 facilitate the connection and disassembly of the valve and the pipeline system.

[0031] The working principle of this utility model is as follows: When the valve opening needs to be adjusted, the electric actuator 1 is started. The connecting column 22 moves up and down under the drive of the electric actuator 1. The connecting column 22 drives the connecting block 23 to move synchronously. The indicator 24 moves in the inner cavity of the mounting cover 21 along with the movement of the connecting block 23. At the same time, the valve stem 26 connected to the bottom of the connecting block 23 also moves up and down with the connecting block 23. When the indicator 24 moves in the mounting cover 21, the operator only needs to observe the corresponding position of the indicator 24 on the reference table 25 to intuitively know the current opening degree of the valve. This allows the operator to adjust the valve opening degree by controlling the electric actuator 1 according to the particle size of the fluid medium containing large particles and the conveying requirements in the actual working conditions, so that the fluid flow rate is adapted to the material characteristics, avoiding excessive wear of valve components due to improper flow rate, and ensuring stable operation of the equipment. When the valve needs to be closed, the electric actuator 1 drives the valve stem 26 to move downward. The valve stem 26 drives the connecting seat 341 and the valve core 342 to move downward until the sealing gasket 343 at the bottom of the valve core 342 is tightly fitted with the valve seat 33. Under the pressure of the valve core 342 and the fluid pressure, the sealing gasket 343 can effectively resist the impact and wear of large particles on the sealing surface, and further enhance the sealing effect, preventing the fluid medium containing large particles from leaking through the gap between the valve seat 33 and the valve core 342, thus achieving the sealing closure of the valve. When the valve needs to be opened, the electric actuator 1 drives the valve stem 26 to move upward, causing the valve core 342 to move upward, so that the valve core 342 separates from the valve seat 33, and the fluid medium containing large particles can flow through the channel inside the valve body 32.

[0032] In the valve's structural design, multiple sealing measures ensure the overall sealing performance of the valve. The sealing rings 6 set at the top and bottom of the valve seat 33 are in close contact with the valve cover 31 and the valve body 32, respectively. During valve assembly, the sealing rings 6 are compressed and deformed, which can fully fill the tiny gaps between the valve seat 33, the valve cover 31, and the valve body 32, forming a double sealing structure. This effectively prevents the leakage of fluid media containing large particles from the connection points. The packing gland 4 at the bottom of the inner cavity of the mounting cover 21 cooperates with the packing group 5 filling between the valve stem 26 and the valve cover 31. The packing group 5 tightly fills the gap between the valve stem 26 and the valve cover 31. The packing gland 4 further compacts the packing group 5 by applying pressure, forming a reliable sealing barrier to prevent the leakage of fluid media containing large particles from the gap between the valve stem 26 and the valve cover 31. At the same time, it can also prevent particle intrusion, reduce wear on the surface of the valve stem 26, and ensure the normal movement of the valve stem 26 and the reliable operation of the valve.
