Description

Technical Field

[0001] This invention relates to the field of regulating valve technology, and more particularly to an anti-clogging regulating valve for sewage pipelines. Background Technology

[0002] In areas such as municipal sewage discharge and industrial wastewater treatment, the accuracy of flow regulation in sewage pipeline systems directly affects the stable operation of the entire sewage transportation and treatment process. As the core component of sewage pipeline flow control, the performance of regulating valves is crucial to the efficient operation of sewage treatment systems.

[0003] Control valves are the final actuators in industrial automation control systems. By receiving standard signals from the controller, they drive internal components to continuously and precisely change the cross-sectional area of ​​the flow channel, thereby achieving automatic adjustment and control of process parameters such as fluid flow rate, pressure, temperature, and liquid level.

[0004] In practical applications, control valves are used in wastewater containing a large amount of heterogeneous impurities, including large particles and heavy impurities such as sand, silt, and solid residue, as well as fine suspended impurities such as flocculent matter, colloidal particles, and fiber fragments. Some industrial wastewater also contains viscous colloidal impurities. These impurities do not have dissolving properties when flowing with the wastewater, and some heavy and viscous impurities have poor flowability and are prone to deposition in areas where the wastewater flow rate slows down. The changes in flow channel diameter and the corners of the cavity inside the control valve can cause a sudden drop in wastewater flow rate, leading to blockage problems such as flow channel jamming, impurity deposition in the valve cavity, filter clogging, and valve core adjustment failure. In mild cases, this can reduce the flow regulation accuracy of the control valve and reduce wastewater flow efficiency; in severe cases, it can cause the valve core to be completely stuck, the flow channel to be blocked, and even cause a sudden increase in pressure in the wastewater pipeline, pipeline rupture and leakage. This not only significantly shortens the service life of the control valve and increases the maintenance and replacement costs of the equipment, but also affects the continuous operation of the wastewater treatment system.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. This invention features an integrated anti-clogging mechanism that combines filtration, cleaning, and collection. It utilizes coarse and fine filters to achieve two-stage interception of large and small particles in wastewater, preventing impurities from entering the valve core gaps, flow channels, and outlet chamber, thus avoiding blockage. The wastewater's own kinetic energy drives the drive assembly, simultaneously moving L-shaped and strip brooms to clean the coarse and fine filters. The filter assembly can move up and down using upper and lower components, ensuring more thorough cleaning and effectively preventing filter clogging. A sludge outlet at the bottom of the valve body, coupled with a threaded collection cylinder, allows for centralized collection of intercepted impurities, preventing their deposition in dead corners of the valve cavity. This solves problems such as flow channel blockage, valve cavity deposition, and sludge discharge failure in regulating valves, extending the valve's lifespan. Furthermore, the coordinated use of the lower and upper components facilitates the up-and-down movement of the coarse and fine filters within the valve body, cleaning impurities from clogging the mesh and ensuring wastewater passes through them. 2. The drive component in this invention operates by relying on the impact kinetic energy of the sewage itself, eliminating the need for external power sources such as motors, thus achieving energy saving and consumption reduction, and significantly reducing equipment operating costs. The collection cylinder and sludge outlet are connected by threads, allowing operators to quickly disassemble, clean, and reposition them. The structural design of each core component is simple and easy to assemble and disassemble, reducing the manpower and time costs of maintenance. At the same time, the anti-clogging structure reduces the frequency of impurity cleaning, further reducing the overall maintenance cost. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1 - Figure 9 The present invention provides a technical solution: A clog-prevention regulating valve for sewage pipelines includes a valve body 1, flange 4 and flange 5 mounted on the top surface of the valve body 1. The valve body 1 has an integrally formed inlet chamber 32, a circular chamber 28, and an outlet chamber 29. The outlet chamber 29 is connected to the circular chamber 28, and the circular chamber 28 is connected to the inlet chamber 32 via a circular opening 30. This interconnection of chambers allows sewage to flow in an orderly manner within the valve body 1, preventing turbulent flow and impurity accumulation. It also provides a reasonable spatial layout for the installation of the valve core 11 and the anti-clogging mechanism, ensuring coordinated operation of all components. The valve core 11 is movably mounted within the circular opening 30, allowing it to move up and down. By adjusting the gap between the valve core 11 and the circular opening 30, precise regulation of the sewage flow can be achieved, adapting to the flow requirements of the sewage pipeline under different operating conditions. The valve core 11 and the circular opening 30... The flexible arrangement of the valve core 11 ensures both flexibility during adjustment and a tight seal between the two, preventing sewage leakage from the gap and improving the accuracy of flow regulation. An annular sealing gasket is fixed to the top outer wall of the valve core 11, and an annular sealing groove matching the annular sealing gasket is opened at the top of the circular opening 30. The use of the annular sealing gasket enhances the seal between the valve core 11 and the circular opening 30, preventing sewage leakage from the gap. One end of the valve body 1 has an inlet 3 communicating with the inlet chamber 32, and the other end has an outlet 10 communicating with the outlet chamber 29. The inlet 3 and outlet 10 are used to connect the regulating valve to the sewage pipe, ensuring that sewage can smoothly enter the valve body 1, be regulated and filtered, and then discharged smoothly, avoiding obstruction of sewage flow and accumulation of impurities due to mismatched interface sizes.

[0021] The bracket 9 is fixed to the top surface of the flange 2 5. The bracket 9 is equipped with an adjustment mechanism for adjusting the valve core 11. By using the adjustment mechanism, the position of the valve core 11 can be adjusted to achieve precise adjustment of the opening degree of the circular opening 30, thereby flexibly controlling the flow rate of sewage.

[0022] The sludge outlet 31 is located on the inner bottom surface of the valve body 1 to discharge the sludge and impurities accumulated inside the valve body 1. This prevents excessive accumulation of impurities on the inner bottom surface of the valve body 1, which could obstruct the flow of sewage. It also provides an installation base for the anti-clogging mechanism and facilitates its disassembly and maintenance. The sludge outlet 31 contains an anti-clogging mechanism to prevent the regulating valve from clogging. This anti-clogging mechanism is an integrated filtration, cleaning, and collection mechanism that can effectively intercept impurities in sewage, promptly clean the deposits on the filter components, collect impurities, and facilitate subsequent cleaning. This fundamentally solves the problem of easy clogging of the regulating valve and improves its service life and operational stability.

[0023] The anti-clogging mechanism includes a collection cylinder 2 threadedly connected inside the sludge outlet 31. The collection cylinder 2 facilitates the collection of impurities and sludge intercepted by the filter components, preventing direct discharge of impurities and secondary blockage of the sewage pipe. It also allows operators to periodically disassemble the collection cylinder 2 to clean the collected impurities, simplifying maintenance. Furthermore, the collection cylinder 2 provides a stable mounting platform for components such as the connecting assembly, connecting shaft 22, and circular box 20, ensuring the coordinated operation of all components of the anti-clogging mechanism. An annular sealing gasket is provided at the top of the collection cylinder 2 to improve the sealing between the collection cylinder 2 and the sludge outlet 31, preventing sewage leakage. The connecting shaft 22 is rotatably mounted inside the collection cylinder 2 via the connecting assembly. The connecting assembly allows for the rotatable installation of the connecting shaft 22 within the collection cylinder 2, while also providing space for its vertical movement. A circular box 20 is rotatably mounted on the outer wall of the connecting shaft 22, and the circular box 20 contains a... The drive assembly that drives the connecting shaft 22 to rotate utilizes the kinetic energy of the sewage itself, eliminating the need for additional power sources such as motors. This saves energy and is adapted to the actual operating conditions of sewage pipelines, reducing equipment operating and maintenance costs. The drive assembly facilitates the rotation of the connecting shaft 22, enabling the cleaning of the coarse filter screen 19 and the fine filter screen 15, preventing clogging and thus facilitating the use of the regulating valve. The top surface of the circular box 20 is equipped with a filter assembly for sewage filtration. This assembly facilitates the filtration of impurities in the sewage, preventing them from clogging the gap between the valve core 11 and the circular opening 30, ensuring flexible adjustment of the valve core 11, and preventing small impurities from clogging the outlet chamber 29 and outlet 10, ensuring smooth sewage discharge and fundamentally improving the anti-clogging performance of the regulating valve. The top of the connecting shaft 22 is equipped with a cleaning assembly that works in conjunction with the filter assembly. The annular cylinder 12 is fixed to the inner bottom of the circular opening 30. The circular opening 30 is provided with a bottom-mounted component for resetting the filter assembly. The use of the bottom-mounted component facilitates the compression of the annular plate 16, thereby resetting the coarse filter screen 19 and the fine filter screen 15.

[0024] In this invention, the driving component includes multiple baffles 38 uniformly fixed inside the circular box 20 and sleeved on the outer wall of the connecting shaft 22. The baffles 38 are slidably fitted with the inner wall of the circular box 20, and the included angle between two adjacent baffles 38 is 60°. This ensures that the force is uniform when sewage impacts the baffles 38, guarantees smooth rotation of the connecting shaft 22, avoids jamming, and ensures that the cleaning component can work continuously and stably. Sewage enters the circular box 20 through the second inlet 37, impacts the baffles 38, and uses the impact force of the sewage to drive the baffles 38 to rotate, thereby driving the connecting shaft 22 to rotate synchronously, providing continuous rotational power for the cleaning component. A second inlet 37 is provided on the outer wall of the circular box 20 to facilitate the entry of sewage into the circular box 20; a second outlet 36 is provided on the top surface of the circular box 20 away from the second inlet 37 to discharge the sewage inside the circular box 20, so as to avoid the accumulation of sewage inside the circular box 20 and ensure the normal operation of the drive component. At the same time, the discharged sewage can enter the filter component for further filtration to achieve orderly flow of sewage.

[0025] In this invention, a coarse filter screen 19 is provided inside the second water inlet 37. The use of the coarse filter screen 19 facilitates the preliminary filtration of sewage entering the circular box 20, intercepts large particulate impurities in the sewage, prevents large particulate impurities from entering the circular box 20 and clogging the gaps between the baffles 38, and avoids jamming and failure of the drive components. At the same time, the coarse filter screen 19 can reduce the filtration pressure of the subsequent filter components, extend the service life of the filter components, and improve the overall filtration effect. An L-shaped broom 21 is fixed to the outer wall of the connecting shaft 22, and the cleaning end of the L-shaped broom 21 is in contact with the outer wall of the circular box 20 and the surface of the coarse filter screen 19, respectively. When the connecting shaft 22 rotates, it will drive the L-shaped broom 21 to rotate synchronously. The cleaning end of the L-shaped broom 21 is in contact with the outer wall of the circular box 20 and the surface of the coarse filter screen 19 to clean. This can remove large particles of impurities attached to the surface of the coarse filter screen 19 in time, avoid clogging of the coarse filter screen 19, ensure smooth water intake of the water inlet 2 37, and ensure that the drive component can obtain continuous power. At the same time, it can clean the sludge and impurities attached to the outer wall of the circular box 20, prevent impurities from accumulating on the outer wall of the circular box 20, and prevent impurities from falling outside the collection cylinder 2, ensuring that all impurities can be collected by the collection cylinder 2.

[0026] In this invention, the filter assembly includes a circular cylinder 18 fixed to the top surface of the circular box 20. The circular cylinder 18 provides a stable mounting carrier for the annular mounting frame 33 and the fine filter screen 15, ensuring the structural stability of the filter assembly and preventing the fine filter screen 15 from deforming or falling off due to sewage impact. The annular mounting frame 33 is fixed inside the circular cylinder 18 by a fixing frame. The fine filter screen 15 is provided inside the annular mounting frame 33. The fine filter screen 15 is used for secondary filtration of sewage, intercepting small impurities in the sewage, preventing small impurities from entering the circular cavity 28 and the outlet cavity 29, avoiding blockage of the gap between the valve core 11 and the circular opening 30, ensuring the flexible adjustment of the valve core 11, and preventing small impurities from blocking the outlet cavity 29 and the outlet 10, ensuring smooth sewage discharge, and fundamentally improving the anti-clogging performance of the regulating valve.

[0027] In this invention, the connector includes a protective cover 39 fixed to the bottom surface of the inner wall of the collection cylinder 2 and an outer cylinder 26 fixed to the bottom surface of the inner wall of the protective cover 39. A movable rod 25 is movably disposed inside the outer cylinder 26. The top of the movable rod 25 is fixed to the bottom of the connecting shaft 22, and the protective cover 39 is rotatably disposed with the connecting shaft 22. The use of the protective cover 39 prevents impurities from falling between the arc plate 24 and the top block 23, thus avoiding jamming and facilitating the rotation of the arc plate 24. The movable rod 25 and the outer cylinder 26 work together to ensure the stability of the connecting shaft 22 during rotation, preventing the connecting shaft 22 from shaking and causing the cleaning component and the filter component to not fit tightly. It also works with the top component to realize the up and down movement of the connecting shaft 22, improving the cleaning effect of the cleaning component. The top of the outer cylinder 26 is provided with an upper lifting assembly. The use of the upper lifting assembly facilitates the raising of the connecting shaft 22, thereby enabling the coarse filter screen 19 and the fine filter screen 15 to rise.

[0028] In this invention, the top assembly includes a plurality of top blocks 23 evenly arranged on the top of the outer cylinder 26. A connecting plate 27 is fixedly connected to the outer wall of the movable rod 25. An arc-shaped plate 24 is fixedly connected to the bottom surface of the connecting plate 27. The top surface of the top block 23 and the side corresponding to the arc surface of the arc-shaped plate 24 are set in an arc shape. When the connecting shaft 22 rotates, it will drive the connecting plate 27 and the arc-shaped plate 24 to rotate synchronously. The arc-shaped surface of the arc-shaped plate 24 and the arc-shaped surface of the top block 23 cooperate with each other. By utilizing the centrifugal force generated by the rotation and the guiding effect of the arc-shaped surface, the movable rod 25 moves up and down inside the outer cylinder 26, thereby driving the connecting shaft 22 and the cleaning assembly to move up and down synchronously.

[0029] In this invention, the lower top assembly includes an annular cavity 14 formed on the bottom surface of the annular cylinder 12. An annular plate 16, which cooperates with the circular cylinder 18, is slidably disposed within the annular cavity 14. The annular plate 16 is slidably disposed within the annular cavity 14 to facilitate the compression of the circular cylinder 18, thereby facilitating the repositioning of the circular cylinder 18. A plurality of compression springs 13 are evenly disposed between the annular plate 16 and the inner wall of the annular cavity 14. The use of the compression springs 13 facilitates the compression of the annular plate 16, thereby repositioning the circular cylinder 18 and further repositioning the coarse filter screen 19 and the fine filter screen 15. The cooperation between the lower top assembly and the upper top assembly facilitates the up-and-down movement of the coarse filter screen 19 and the fine filter screen 15 within the valve body 1, facilitating the cleaning of impurities on the coarse filter screen 19 and the fine filter screen 15, preventing impurities from clogging the mesh of the coarse filter screen 19 and the fine filter screen 15, and ensuring that sewage passes through the coarse filter screen 19 and the fine filter screen 15.

[0030] In this invention, a plurality of insert rods 17 are uniformly fixed to the bottom surface of the annular plate 16, and a plurality of insertion holes are uniformly opened on the top surface of the cylindrical cylinder 18 corresponding to the insert rods 17. The cooperation between the insert rods 17 and the insertion holes can position the cylindrical cylinder 18, preventing the cylindrical cylinder 18 from rotating under the influence of sewage impact and the rotation of the connecting shaft 22, ensuring the fitting accuracy between the strip broom 34 and the fine filter screen 15, and improving the cleaning effect. At the same time, it also improves the stability of the connection between the cylindrical cylinder 18 and the annular plate 16, facilitates the dispersion of the force borne by the cylindrical cylinder 18, prevents the connecting shaft 22 from breaking, and effectively extends the service life of the connecting shaft 22.

[0031] In this invention, the cleaning assembly includes a circular plate 35 fixed to the top of the connecting shaft 22. Multiple strip brooms 34 are uniformly fixed to the outer wall of the circular plate 35, and the cleaning ends of the strip brooms 34 are in contact with the bottom surface of the fine filter screen 15. When the connecting shaft 22 rotates, it drives the circular plate 35 and the strip brooms 34 to rotate synchronously. The cleaning ends of the strip brooms 34 are in contact with the bottom surface of the fine filter screen 15 for thorough cleaning, which can promptly remove small impurities attached to the bottom surface of the fine filter screen 15, preventing small impurities from clogging the mesh of the fine filter screen 15, ensuring the filtration efficiency of the fine filter screen 15, preventing poor sewage flow and increased pressure in the pipeline due to clogging of the fine filter screen 15, thereby protecting the overall structure of the regulating valve and extending its service life.

[0032] In this invention, the adjusting mechanism includes a threaded sleeve 6 fixed to the bracket 9 and a valve stem 7 threadedly connected to the threaded sleeve 6. The top of the valve stem 7 movably passes through the top of the bracket 9 and is fixedly connected to a handle 8. The use of the handle 8 facilitates manual adjustment by the operator without the need for additional tools, thus improving operational convenience. The bottom movably passes through flange 2 5, flange 1 4 and valve body 1 and extends into the circular cavity 28, and is fixedly connected to the valve core 11. Through the use of the threaded sleeve 6 and the valve stem 7, the valve core 11 can move up and down synchronously within the circular opening 30, thereby achieving precise adjustment of the opening degree of the circular opening 30 and flexibly controlling the flow rate of sewage.

[0033] Working principle: When in use, sewage enters the inlet chamber 32 from the inlet 3 at one end of the valve body 1. The operator can achieve precise control of sewage flow through the adjustment mechanism. Specifically, the operator manually rotates the handle 8 at the top of the bracket 9, which drives the valve rod 7 inside the threaded sleeve 6 to move up and down linearly. This causes the valve core 11 to move up and down synchronously within the circular opening 30 that connects the inlet chamber 32 and the circular cavity 28. By changing the gap between the valve core 11 and the circular opening 30, the flow rate of sewage from the inlet chamber 32 into the circular cavity 28 and the outlet chamber 29 can be controlled. When sewage flows from the inlet chamber 32 to the circular chamber 28, it impacts the circular box 20 of the anti-clogging mechanism. Some sewage enters the interior of the circular box 20 through the inlet 37 on the outer wall of the circular box 20. The coarse filter 19 inside the inlet 37 first performs preliminary filtration of the sewage, intercepting large particulate impurities in the sewage and preventing them from entering the interior of the circular box 20 and causing blockage. The sewage entering the circular box 20 impacts the baffles 38 that are evenly distributed inside the box. The kinetic energy of the sewage itself drives the baffles 38 to rotate around the connecting shaft 22, thereby driving the connecting shaft 22 to rotate synchronously. When the connecting shaft 22 rotates, it synchronously drives the L-shaped broom 21 on its outer wall and the cleaning component on top to rotate, achieving comprehensive cleaning of the coarse filter screen 19 and the fine filter screen 15: when the cleaning end of the L-shaped broom 21 is in close contact with the outer wall of the circular box 20 and the surface of the coarse filter screen 19, large particles of impurities attached to the coarse filter screen 19 are removed in time during the rotation process, preventing the mesh of the coarse filter screen 19 from being blocked, ensuring that the sewage in the inlet 2 37 enters smoothly, and continuously providing power to the drive component. At the same time, it cleans the sludge and impurities on the outer wall of the circular box 20, preventing them from accumulating and falling to form new blockage points. The circular plate 35 at the top of the connecting shaft 22 rotates with the shaft, causing multiple strip brooms 34 on its outer wall to rotate synchronously. The cleaning ends of the strip brooms 34 are in close contact with the bottom surface of the fine filter screen 15 of the filter assembly on the top surface of the circular box 20, which performs secondary cleaning on the fine filter screen 15, removes the small impurities intercepted on the fine filter screen 15, prevents the fine filter screen 15 from clogging, which would lead to poor sewage flow and increased pressure in the pipe, and facilitates the flow of sewage. As the connecting shaft 22 rotates, it drives the movable rod 25 fixed to the bottom of the connecting shaft 22 to rotate synchronously inside the outer cylinder 26. The connecting plate 27 on the outer wall of the movable rod 25 rotates with the shaft. The arc plate 24 on its bottom surface cooperates with the top block 23 on the top of the outer cylinder 26. Using the centrifugal force of rotation and the guiding effect of the arc surface, the movable rod 25 moves up and down inside the outer cylinder 26, thereby driving the connecting shaft 22, the circular box 20 and the filter assembly on the top to move up and down as a whole. This facilitates the movement of the coarse filter screen 19 and the fine filter screen 15 in the sewage, making it easier to clean the impurities on the coarse filter screen 19 and the fine filter screen 15, preventing the mesh of the coarse filter screen 19 and the fine filter screen 15 from being blocked, and promoting water flow. Wastewater that has undergone preliminary filtration by coarse filter screen 19 and secondary filtration by fine filter screen 15 is discharged from outlet 36 of circular box 20, away from inlet 37, and enters circular cavity 28 of valve body 1. It then flows into outlet cavity 29 through circular cavity 28 and is finally discharged from outlet 10 at the other end of valve body 1, thus completing the filtration and flow of wastewater. Impurities intercepted by coarse filter screen 19 and impurities swept off by L-shaped broom 21 fall into collection cylinder 2 on the bottom surface of valve body 1 under the action of gravity, thus achieving centralized collection of impurities. The collecting cylinder 2 and the mud outlet 31 of the valve body 1 are connected by a thread. The operator can periodically unscrew the collecting cylinder 2 from the mud outlet 31 to clean the various impurities collected inside. After cleaning, the collecting cylinder 2 can be screwed back into the mud outlet 31 to resume use.
