Description

A high-performance butterfly valve capable of automatic pressure regulation Technical Field

[0001] This invention relates to the field of butterfly valve technology, specifically a high-performance butterfly valve capable of automatic pressure regulation. Background Technology

[0002] With the continuous improvement of industrial automation, butterfly valves are widely used in petrochemical, environmental protection, water treatment, food and pharmaceutical industries. Traditional butterfly valves have evolved to include manual, pneumatic, and electric actuation methods, basically meeting the flow regulation and pipeline shut-off needs of most operating conditions. However, with increasingly stringent requirements for process precision, safety, and cleanliness, traditional butterfly valves are proving inadequate in terms of self-cleaning, sealing reliability, and pressure safety management. Therefore, the industry has begun exploring the application of more sensors and composite technologies such as electromagnetics and hydraulics in butterfly valves to meet stricter control, cleanliness, and safety standards. In the future, butterfly valves will have broader application prospects in precision manufacturing, high-end equipment, and intelligent manufacturing, and more innovative products integrating multidisciplinary technologies will emerge.

[0003] Currently, butterfly valves on the market typically employ single mechanical or electric control. While they possess basic on / off functions, most remain at a purely passive execution level. Some improved butterfly valves have begun to incorporate simple differential pressure or flow detection devices to assist in determining valve opening / closing status or pipeline pressure. However, these improved products usually only offer unidirectional regulation triggered by alarms or passive commands, lacking adaptive capabilities and comprehensive self-cleaning functions. For high-viscosity fluids or conditions containing impurities, filters or centrifugal flushing devices are commonly added upstream of the valve, which is costly and cumbersome. Furthermore, for high-pressure systems, traditional pressure relief methods often employ a combination of separate pressure relief valves and pressure limiting valves, separating monitoring from action. This not only limits response speed but also easily leads to maintenance difficulties.

[0004] Regarding the aforementioned technologies, firstly, traditional butterfly valves generally lack self-cleaning mechanisms, requiring periodic shutdowns for cleaning when using fluids containing impurities or prone to scaling, wasting manpower and time. Secondly, while most traditional butterfly valves possess a certain level of sealing performance, they do not adequately address the valve disc sealing life and reliability under high pressure or frequent opening and closing scenarios. Furthermore, they lack eccentric mechanisms to adjust for different pressures on both sides and multi-stage sealing structures, resulting in unstable valve disc fit during operation. Finally, for pressure monitoring and relief, traditional technologies often require additional pressure monitoring systems and external pressure relief channels. Therefore, those skilled in the art provide a high-performance butterfly valve capable of automatic pressure regulation to address the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a high-performance butterfly valve capable of automatic pressure regulation to solve the problems raised in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The butterfly valve includes a valve control mechanism, a self-cleaning mechanism, an eccentric mechanism, and a pressure relief mechanism. The valve control mechanism and the self-cleaning mechanism are connected, the eccentric mechanism and the valve control mechanism are fastened together, the pressure relief mechanism and the valve control mechanism are connected, the self-cleaning mechanism and the valve control mechanism are fastened together, and the pressure relief mechanism and the self-cleaning mechanism are connected.

[0008] By adopting the above technical solution, the valve control mechanism is securely connected to the valve body via a pneumatic actuator, enabling the motor to precisely control the movement of the valve disc. The control components work in coordination with parts such as the control shaft and sliding block to ensure the opening and closing of the valve disc. The self-cleaning mechanism uses a cleaning motor to drive the transmission components, allowing the cleaning block to clean the valve body surface and prevent the accumulation of dirt. The eccentric mechanism uses a combination of hydraulic cylinder and eccentric block to adjust the eccentric movement of the valve disc, improving sealing. The pressure relief mechanism monitors and adjusts the pressure in real time through a pressure sensor to prevent equipment damage. All mechanisms work together through interconnected and secure designs, ensuring that the valve does not leak during opening and closing and can automatically clean and regulate pressure. The valve control mechanism, eccentric mechanism, and pressure relief mechanism cooperate to ensure precise valve control and pressure regulation; the self-cleaning mechanism ensures long-term cleanliness inside the valve, avoiding the impact of dirt on performance, thus giving the equipment good sealing performance, cleaning efficiency, and safety.

[0009] Furthermore, the valve control mechanism includes a valve body, a pneumatic actuator, a control component, and a valve disc. The pneumatic actuator is fastened to the valve body, the pneumatic actuator is driven to the control component, the control component is driven to the valve disc, the valve disc is circular, and the valve disc has an abutment point with rounded corners. The valve disc abuts against the eccentric mechanism.

[0010] By adopting the above technical solution, the valve control mechanism includes a valve body, a pneumatic actuator, a control component, and a valve disc. The pneumatic actuator is rigidly connected to the valve body. The pneumatic actuator and the control component are driven together to provide power output to the control component. The control component is driven together with the valve disc, causing the valve disc to rotate. The valve disc is circular and has a rounded contact point. The contact point is rounded and abuts against the eccentric block of the eccentric mechanism. The pneumatic actuator precisely adjusts the opening and closing of the valve disc through the control component, ensuring that the valve can adjust the fluid flow according to the demand. The pneumatic actuator drives the movement of the control component, thereby driving the valve disc to open and close. The rounded contact point reduces friction and extends the service life of the valve. The design of the valve control mechanism improves the accuracy of the valve and ensures stable operation over a long period of time.

[0011] Furthermore, the control assembly includes a control shaft, a sliding block, a connecting column, a control block, a clamping electromagnetic block, a clamping elastic element, and a clamping magnetic block. The pneumatic actuator is driven to the control shaft, the control shaft is driven to the connecting column, the connecting column is driven to the sliding block, the sliding block and the control block are slidably connected, the clamping electromagnetic block and the control block are fastened together, the clamping electromagnetic block and the clamping elastic element are fastened together, the clamping magnetic block and the clamping elastic element are fastened together, the clamping magnetic block and the clamping electromagnetic block are driven by magnetic repulsion, and the clamping magnetic block and the control block are slidably connected.

[0012] By adopting the above technical solution, the control shaft is connected to the pneumatic actuator, transmitting the rotational power output by the motor to downstream components. The sliding block can slide or reciprocate within the control block, used to adjust the valve disc after the eccentric angle is adjusted for transmission. The connecting column connects the control shaft and components such as the sliding block, serving a transmission function. The control block acts as a guide and mounting base for the sliding block's movement, cooperating with components such as the clamping electromagnetic block and clamping magnetic block. The clamping electromagnetic block is securely connected to the control block, controlling the movement or positioning of the clamping magnetic block through electromagnetic force. The clamping elastic element is securely connected to the clamping electromagnetic block and clamping magnetic block, providing the necessary elastic force. The clamping transmission operates based on magnetic repulsion or attraction. The clamping magnetic block and the clamping electromagnetic block exhibit magnetic repulsion and can slide within the control block to achieve clamping and releasing of the valve disc. When the pneumatic actuator operates, the control shaft drives the connecting column and sliding block to move. Through the electromagnetic force between the clamping electromagnetic block and the clamping magnetic block, the transmission path for precise adjustment of the clamping state is achieved. By utilizing magnetic repulsion and elastic buffering, the motor drive and clamping mechanism are combined, improving the stability and flexibility of valve opening and closing control. This ensures the smoothness and accuracy of the valve control mechanism when performing switching actions, effectively avoiding the wear and noise problems of traditional mechanical cooperation.

[0013] Furthermore, the eccentric mechanism includes a first eccentric block, a second eccentric block, a third eccentric block, a first sealing ring, a second sealing ring, a first eccentric hydraulic cylinder, and a second eccentric hydraulic cylinder. Four first eccentric blocks and four first sealing rings are provided. The first eccentric block abuts against the valve disc, the first sealing ring is fastened to the first eccentric block, the second sealing ring is fastened to the valve disc, the first eccentric block and the second eccentric block are slidably connected, the second eccentric block and the third eccentric block are slidably connected, the third eccentric block is fastened to the valve body, the second eccentric hydraulic cylinder is fastened to the third eccentric block, the second eccentric hydraulic cylinder and the second eccentric block are drive-connected, the first eccentric hydraulic cylinder and the second eccentric block are fastened to each other, and the first eccentric hydraulic cylinder and the first eccentric block are drive-connected.

[0014] By adopting the above technical solution, the first, second, and third eccentric blocks are connected by a sliding connection to form an eccentric structure. Simultaneously, the eccentric movement of the valve disc during opening and closing is achieved through pressure changes on both sides, enhancing the sealing effect. The first sealing ring is tightly connected to the first eccentric block, forming a multi-point sealing structure to prevent fluid leakage. The second sealing ring is tightly connected to the valve disc, forming a sealing interface in the contact area between the valve disc and the first eccentric block. The first and second eccentric hydraulic cylinders are respectively connected to the first and second eccentric blocks for transmission. Hydraulic driving of the eccentric blocks further fine-tunes the position and fit of the valve disc. During control, the eccentric hydraulic cylinder pushes or pulls the eccentric blocks to form a linear movement, causing a slight eccentricity in the valve disc, thereby achieving higher sealing performance. Utilizing the sliding connection between the eccentric blocks and the driving force of the hydraulic cylinders, efficient sealing and fit are maintained throughout the opening and closing process. Through the coordination of multi-stage eccentric linear movements, the valve achieves excellent sealing performance and pressure resistance, reducing wear and extending service life.

[0015] Furthermore, the first and second sealing rings are sealed with an S-shaped cross-section, and the first eccentric block is provided with an abutment groove. The second sealing ring abuts against the abutment groove. The first eccentric block, the second eccentric block, the third eccentric block, and the first sealing ring are all crescent-shaped.

[0016] By adopting the above technical solution, the first and second sealing rings, with S-shaped cross-sections, are wrapped around the eccentric block and valve disc, maintaining a stable seal during dynamic eccentric movement. The abutment groove (located on the first eccentric block) abuts against the second sealing ring, ensuring reliable positioning and support during eccentric movement. The crescent-shaped eccentric block and sealing rings geometrically better conform to the circular structure of the valve disc, providing a larger contact surface during opening and closing, thus enhancing the sealing effect. The S-shaped cross-section sealing rings combined with the crescent-shaped... The eccentric block reduces uneven contact and wear on the sealing surface. The abutment groove design provides more stable positioning for the sealing ring when the valve disc opens and closes. When the valve disc moves eccentrically, the second sealing ring cooperates with the abutment groove, and the first sealing ring is tightly connected to the first eccentric block, forming multiple surrounding sealing areas. The S-shaped cross-section enhances the elastic fit of the sealing ring to the sealing surface after being stressed. The crescent-shaped eccentric block can naturally fit with the circular structure of the valve disc, improving sealing reliability and effectively enhancing the sealing performance of the valve in the eccentric state, thus extending the service life of the sealing components.

[0017] Furthermore, the self-cleaning mechanism includes a first cleaning block, a second cleaning block, a cleaning motor, and a transmission assembly. The cleaning motor and the valve body are fastened together, the cleaning motor and the transmission assembly are driven together, the transmission assembly and the first cleaning block are driven together, and the transmission assembly and the second cleaning block are driven together. The first cleaning block is provided with a first flow stabilizing groove, and the second cleaning block is provided with a second flow stabilizing groove. The first flow stabilizing groove and the second flow stabilizing groove are connected. Both the first flow stabilizing groove and the second flow stabilizing groove are spiral-shaped around the axis of the first cleaning block. The first cleaning block is provided with a cleaning cavity, and the second cleaning block is provided with a connecting cavity. The cleaning cavity and the connecting cavity are connected. The cleaning cavity is hemispherical, and the connecting cavity is cylindrical. The first flow stabilizing groove is arranged circumferentially in the cleaning cavity, and the second flow stabilizing groove is arranged circumferentially in the connecting cavity.

[0018] By adopting the above technical solution, the first and second cleaning blocks rotate under the drive of the cleaning motor to clean the inside of the valve body and the surface of the valve disc. The cleaning motor is fastened to the valve body and connected to the transmission assembly to provide power to the cleaning blocks. The transmission assembly transmits the power of the cleaning motor to the first and second cleaning blocks respectively, achieving coordinated cleaning. The first flow stabilizing groove (located on the first cleaning block) and the second flow stabilizing groove (located on the second cleaning block) are both spiral-shaped and interconnected, which can guide the fluid or cleaning liquid to flow along the spiral path. The cleaning chamber (located on the first cleaning block) The inner and connecting chambers (located within the second cleaning block) are hemispherical and cylindrical structures, respectively, and are connected to each other. They are used to store cleaning fluid or collect dirt. Together with the flow stabilizing groove, they improve the cleaning effect. The cleaning motor is fixed on the valve body, and the output power is distributed to the two cleaning blocks through the transmission component, so that they rotate or reciprocate at the corresponding positions inside and outside the valve body for cleaning. A continuous and stable fluid channel is formed through the spiral flow stabilizing groove. The structural advantages of the cleaning chamber and the connecting chamber are used to carry away or collect dirt, ensuring that the valve can still maintain a good condition after long-term use and reducing failures or performance degradation caused by dirt accumulation.

[0019] Furthermore, the transmission assembly includes a transmission gear rod, a reversing solenoid block, a reversing magnetic block, a reversing gear rod assembly, and a driven gear rod. The cleaning motor and the transmission gear rod are connected by transmission, the transmission gear rod and the driven gear rod are connected by transmission, the driven gear rod and the first cleaning block are connected by transmission, the transmission gear rod and the reversing gear rod assembly are connected by insertion, the driven gear rod and the reversing gear rod assembly are connected by insertion, the reversing gear rod assembly and the reversing magnetic block are fastened together, the reversing gear rod assembly and the valve body are rotatably connected, and the reversing gear rod assembly and the second cleaning block are connected by transmission.

[0020] By adopting the above technical solution, the transmission gear rod transmits the rotational motion of the cleaning motor to the driven gear rod and the reversing gear rod assembly. The reversing electromagnetic block and the reversing magnetic block interact to form the linear motion of the reversing gear rod assembly. The direction of gear transmission or the distribution of power path is controlled by electromagnetic force. The reversing magnetic block is tightly connected to the reversing gear rod assembly, and the power reversal or distribution is realized through magnetic cooperation. The reversing gear rod assembly can be connected to the transmission gear rod or the driven gear rod by plugging in, switching the second cleaning block to different rotation directions. The driven gear rod is connected to the first cleaning block by transmission, thereby achieving the purpose of rotating the first cleaning block. At the same time, it can be plugged in with the reversing gear rod assembly to drive the second cleaning block. The output shaft of the cleaning motor is connected to the transmission gear rod. Under the action of the reversing electromagnetic block and the reversing magnetic block, the reversing gear rod assembly can selectively transmit power to the first or second cleaning block.

[0021] By using electromagnetic commutation to switch gear sets, a single motor can drive multiple cleaning components, enabling multi-part cleaning within limited space and power source, thus improving the working efficiency and flexibility of the self-cleaning mechanism.

[0022] Furthermore, the reversing gear assembly includes a first reversing rod, a second reversing rod, a first reversing gear, and a second reversing gear. The first reversing rod and the transmission gear rod are connected by insertion and transmission. The second reversing rod and the second reversing gear are connected by insertion and transmission. The first reversing rod and the first reversing gear are connected by transmission. The second reversing rod and the second reversing gear are connected by transmission. The second reversing rod and the first reversing gear are rotatably connected.

[0023] By adopting the above technical solution, the first reversing rod is plugged into the transmission gear rod, and the power input or transmission is realized through the first reversing gear. The second reversing rod is plugged into the second reversing gear, and the second cleaning block is driven by rotation or turning. The first reversing gear is driven into the first reversing rod, and is rotatably connected to the second reversing rod for power transmission between different gears. The second reversing gear is plugged into the second reversing rod and can receive or output the power transmitted from the first reversing gear. Through the combination of multiple rods and multiple gears, the power distribution of different directions and different components can be realized to meet complex cleaning needs. When the transmission gear rod drives the first reversing rod to rotate, the rotation or meshing relationship between the first reversing gear and the second reversing rod can be switched or synchronized to realize the drive of the second reversing gear. With the help of the plugged gear rod combination, power reversal and distribution can be realized in a limited space, and the cleaning blocks can be switched or rotated synchronously through the reversing gear.

[0024] Improving the mobility of the self-cleaning mechanism enables cleaning actions at multiple angles and in multiple directions within a single gear transmission system.

[0025] Furthermore, the pressure relief mechanism includes a pressure relief pipe, a pressure relief valve, a first pressure sensor, a second pressure sensor, an impeller, and a pressure relief box. The pressure relief pipe is connected to the valve body, the pressure relief valve is fastened to the valve, the pressure relief valve is connected to the pressure relief pipe, the pressure relief valve is located at the lower end of the valve body, the first pressure sensor is fastened to the valve body, the second pressure sensor is fastened to the valve body, the first pressure sensor is fastened to the first eccentric block, the pressure relief pipe is connected to the pressure relief box, and the control shaft is driven to the impeller.

[0026] By adopting the above technical solution, the pressure relief pipe is connected to the valve body and is used to discharge fluid or introduce it into the pressure relief box when the pressure exceeds the limit. The pressure relief valve is fixedly connected to the valve body, located at the lower end of the valve body, and is connected to the pressure relief pipe. It is responsible for automatically opening or closing the discharge channel. The first pressure sensor is fixed to the first eccentric block, and the second pressure sensor is fixed to the valve body. It is used to monitor the pressure data inside the valve body or at the eccentric structure in real time. The impeller is driven by the control shaft. The impeller is driven to rotate by the control shaft. When the valve or pressure relief process is in progress, it can help guide the fluid flow or generate measurement data. The pressure relief box is connected to the pressure relief pipe and is used to collect or store the discharged excess fluid to ensure system safety. When the sensor detects that the pressure inside the valve body exceeds the preset range, the pressure relief valve automatically opens under the control signal command or its own mechanical setting, and introduces the excess fluid into the pressure relief box through the pressure relief pipe. By utilizing the real-time detection of pressure sensors and the linkage of pressure relief valves, excessive pressure on pipelines or valve bodies can be avoided. During this process, the impeller can assist in fluid discharge or provide additional detection signals through its rotational speed, effectively preventing equipment damage or safety accidents caused by pressure overload and ensuring long-term stable and reliable operation of the system.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows: First, by forming an eccentric system through sliding or fastening connections of the first eccentric block, the second eccentric block, and the third eccentric block, the eccentric movement of the valve disc during the opening and closing process is realized, enhancing the sealing effect. The first sealing ring is fastened to the first eccentric block, forming a multi-point sealing structure to prevent fluid leakage. The second sealing ring is fastened to the valve disc, forming a sealing interface in the contact area between the valve disc and the first eccentric block. The first eccentric hydraulic cylinder and the second eccentric hydraulic cylinder are respectively connected to the first and second eccentric blocks for transmission. By hydraulically driving the eccentric blocks to move, the position and fit of the valve disc are further fine-tuned. When controlled, the eccentric hydraulic cylinder pushes or pulls the eccentric block, causing the valve disc to produce a slight eccentricity, thereby obtaining higher sealing performance. By utilizing the sliding connection between the eccentric blocks and the driving force of the hydraulic cylinder, efficient sealing fit is maintained throughout the opening and closing process. Through multi-stage eccentric cooperation, good sealing performance and pressure resistance of the valve are achieved, reducing wear and extending service life. Secondly, the first cleaning block and the second cleaning block move under the drive of the cleaning motor. The cleaning motor, which is fixedly connected to the valve body and driven by the transmission assembly, provides power to the cleaning blocks. The transmission assembly transmits the power of the cleaning motor to the first and second cleaning blocks respectively, achieving coordinated cleaning. The first and second flow stabilizing grooves (located on the first and second cleaning blocks) are both spiral-shaped and interconnected, guiding the fluid or cleaning liquid to flow along the spiral path. The cleaning chamber (located in the first cleaning block) and the connecting chamber (located in the second cleaning block) are hemispherical and cylindrical structures respectively, connected to each other, used to store cleaning liquid or collect dirt. Together with the flow stabilizing grooves, they improve the cleaning effect. The cleaning motor is fixed to the valve body, and the output power is distributed to the two cleaning blocks through the transmission assembly, causing them to rotate or reciprocate at corresponding positions inside and outside the valve body for cleaning. The spiral flow stabilizing grooves form a continuous and stable fluid channel. The structural advantages of the cleaning chamber and the connecting chamber are used to carry away or collect dirt, ensuring that the valve can maintain a good condition after long-term use and reducing failures or performance degradation caused by dirt accumulation.

The valve disc 14 is circular and has an abutment 141 with rounded corners. The valve disc 14 abuts against the eccentric mechanism 3.

[0042] By adopting the above technical solution, the valve control mechanism 1 includes a valve body 11, a pneumatic actuator 12, a control component 13, and a valve disc 14. The pneumatic actuator 12 is rigidly connected to the valve body 11. The pneumatic actuator 12 and the control component 13 are connected by a transmission to provide power output to the control component 13. The control component 13 is connected by a transmission to the valve disc 14, causing the valve disc 14 to rotate. The valve disc 14 is circular and has a contact point 141 with rounded corners. The valve disc 14 abuts against the eccentric block of the eccentric mechanism 3. The pneumatic actuator 12 precisely adjusts the opening and closing of the valve disc 14 through the control component 13 to ensure that the valve can adjust the fluid flow rate as needed.

The clamping elastic element 136 is securely connected to the clamping electromagnetic block 135 and the clamping magnetic block 137. The necessary elastic force is provided for clamping and transmission when magnetic repulsion or attraction occurs. The clamping magnetic block 137 and the clamping electromagnetic block 135 have magnetic repulsion transmission and can slide within the control block 134 to achieve clamping and release of the valve disc 14. When the pneumatic actuator 12 works, the control shaft 131 drives the connecting column 133 and the sliding block 132 to move. Through the electromagnetic force between the clamping electromagnetic block 135 and the clamping magnetic block 137, the transmission path of the clamping state is precisely adjusted. By using magnetic repulsion and elastic buffer, the motor drive and clamping mechanism are combined, which improves the stability and flexibility of valve opening and closing control, ensures the smoothness and accuracy of the valve control mechanism 1 when performing switching actions, and effectively avoids the wear and noise problems of traditional mechanical cooperation.

The first sealing ring 34 is tightly connected to the first eccentric block 31, forming a multi-point sealing structure to prevent fluid leakage. The second sealing ring 35 is tightly connected to the valve disc 14, forming a sealing interface in the contact area between the valve disc 14 and the first eccentric block 31. The first eccentric hydraulic cylinder 36 and the second eccentric hydraulic cylinder... 37 is connected to the first and second eccentric blocks 32 respectively. The eccentric blocks are driven by hydraulic power to move, further fine-tuning the position and fit of the valve disc 14. When controlled, the eccentric hydraulic cylinder pushes or pulls the eccentric blocks to form a linear motion, causing the valve disc 14 to produce a slight eccentricity, thereby obtaining higher sealing performance. By utilizing the sliding connection between the eccentric blocks and the driving force of the hydraulic cylinder, it is ensured that a highly efficient sealing fit is maintained during the opening and closing process. Through the coordination of multi-stage eccentric linear motion, the valve achieves good sealing performance and pressure resistance, reduces wear, and extends service life.

[0047] Furthermore, the first sealing ring 34 and the second sealing ring 35 are sealed with an S-shaped cross section, and the first eccentric block 31 is provided with an abutment groove 311. The second sealing ring 35 abuts against the abutment groove 311. The first eccentric block 31, the second eccentric block 32, the third eccentric block 33 and the first sealing ring 34 are all crescent-shaped.

[0048] By adopting the above technical solution, the first sealing ring 34 and the second sealing ring 35, which are S-shaped in cross-section, are connected to the eccentric block and valve disc 14 in a circumferential manner, and can maintain a stable fit and seal during dynamic eccentric movement. The abutment groove 311 (set on the first eccentric block 31) is used to abut against the second sealing ring 35, so that the sealing ring has reliable positioning and support during eccentric movement. The crescent-shaped eccentric block and sealing ring are geometrically more in line with the circular structure of the valve disc 14, which can provide a larger contact surface when opening or closing, and enhance the sealing effect. The S-shaped cross-section sealing ring is combined with the crescent-shaped eccentric block. The design of the first eccentric block 31 reduces uneven contact and wear on the sealing surface. The design of the abutment groove 311 provides more stable positioning for the sealing ring when the valve disc 14 is opened and closed. When the valve disc 14 moves eccentrically, the second sealing ring 35 cooperates with the abutment groove 311, and the first sealing ring 34 is tightly connected with the first eccentric block 31, forming multiple surrounding sealing areas. The S-shaped cross section enhances the elastic fit of the sealing ring to the sealing surface after being stressed. The crescent-shaped eccentric block can naturally fit with the circular structure of the valve disc 14, improving sealing reliability and effectively enhancing the sealing performance of the valve in the eccentric state, thus extending the service life of the sealing components.

[0050] By adopting the above technical solution, the first cleaning block 21 and the second cleaning block 22 rotate under the drive of the cleaning motor 23 to clean the inside of the valve body 11 and the surface of the valve disc 14. The cleaning motor 23 is fastened to the valve body 11 and driven by the transmission assembly 24 to provide power to the cleaning blocks. The transmission assembly 24 transmits the power of the cleaning motor 23 to the first cleaning block 21 and the second cleaning block 22 respectively to achieve coordinated cleaning. The first flow stabilizing groove 212 (located on the first cleaning block 21) and the second flow stabilizing groove 221 (located on the second cleaning block 22) are both spiral-shaped and interconnected, which can guide the fluid or cleaning liquid to flow along the spiral path.

A continuous and stable fluid channel is formed through the spiral flow stabilizing groove. The structural advantages of the cleaning cavity 211 and the connecting cavity 222 are used to carry away or collect dirt, ensuring that the valve can still maintain a good condition after long-term use and reducing failures or performance degradation caused by dirt accumulation.

[0051] Furthermore, the transmission assembly 24 includes a transmission gear rod 241, a reversing electromagnetic block 242, a reversing magnetic block 243, a reversing gear rod assembly 244, and a driven gear rod 245.

[0052] By adopting the above technical solution, the transmission gear 241 transmits the rotational motion of the cleaning motor 23 to the driven gear 245 and the reversing gear assembly 244. The reversing electromagnetic block 242 and the reversing magnetic block 243 interact to form the linear motion of the reversing gear assembly 244. The direction of gear transmission or the distribution of power path is controlled by electromagnetic force. The reversing magnetic block 243 is tightly connected to the reversing gear assembly 244, and the power reversal or distribution is realized through magnetic cooperation.

The driven gear rod 241 or driven gear rod 245 is connected to switch the second cleaning block to different rotation directions. The driven gear rod 245 is connected to the first cleaning block 21 for transmission, thereby achieving the purpose of rotating the first cleaning block 21. At the same time, it can be plugged into the reversing gear rod group 244 to drive the second cleaning block 22. The output shaft of the cleaning motor 23 is connected to the transmission gear rod 241. Under the action of the reversing electromagnetic block 242 and the reversing magnetic block 243, the reversing gear rod group 244 can selectively transmit power to the first or second cleaning block 22.

[0053] By using electromagnetic commutation to switch gear sets, a single motor can drive multiple cleaning components, enabling multi-part cleaning within limited space and power source, thus improving the working efficiency and flexibility of the self-cleaning mechanism 2.

[0054] Furthermore, the reversing gear linkage 244 includes a first reversing lever 2441, a second reversing lever 2442, a first reversing gear 2443, and a second reversing gear 2444.

[0055] By adopting the above technical solution, the first reversing rod 2441 is plugged into the transmission gear rod 241, and the first reversing gear 2443 realizes the input or transmission of power. The second reversing rod 2442 is plugged into the second reversing gear 2444, and the second cleaning block 22 is driven by rotation or turning.

With the help of the plug-in gear rod combination, the power reversal and distribution can be realized in a limited space. The cleaning blocks can be switched or rotated synchronously through the reversing gears.

[0056] The mobility of the self-cleaning mechanism 2 is improved, enabling cleaning actions at multiple angles and in multiple directions within a single gear transmission system.

[0057] Furthermore, the pressure relief mechanism 4 includes a pressure relief pipe 41, a pressure relief valve 42, a first pressure sensor 43, a second pressure sensor 44, an impeller 45, and a pressure relief box 46. The pressure relief pipe 41 is connected to the valve body 11, the pressure relief valve 42 is fastened to the valve, the pressure relief valve 42 is connected to the pressure relief pipe 41, the pressure relief valve 42 is located at the lower end of the valve body 11, the first pressure sensor 43 is fastened to the valve body 11, the second pressure sensor 44 is fastened to the valve body 11, the first pressure sensor 43 is fastened to the first eccentric block 31, the pressure relief pipe 41 is connected to the pressure relief box 46, and the control shaft 131 is drivenly connected to the impeller 45.

It is used to monitor the pressure data inside the valve body 11 or at the eccentric structure in real time. The impeller 45 is driven by the control shaft 131. The control shaft 131 drives the impeller 45 to rotate. When the valve or pressure relief process is in progress, it can assist in guiding the fluid flow or generate a measurement. The pressure relief tank 46 is connected to the pressure relief pipe 41 to collect or store excess fluid discharged to ensure system safety. When the sensor detects that the pressure inside the valve body 11 exceeds the preset range, the pressure relief valve 42 automatically opens under the command of the control signal or its own mechanical setting, and the excess fluid is introduced into the pressure relief tank 46 through the pressure relief pipe 41. The real-time detection of the pressure sensor is linked with the action of the pressure relief valve 42 to avoid the pipeline or valve body 11 from being subjected to excessive pressure. The impeller 45 can assist in the discharge of fluid or provide additional detection signals through its rotation speed during this process, effectively preventing equipment damage or safety accidents caused by pressure overload and ensuring the long-term stable and reliable operation of the system.

[0059] The working principle of this invention is as follows: First, an eccentric system is formed by sliding or fastening the first eccentric block 31, the second eccentric block 32, and the third eccentric block 33, realizing the eccentric movement of the valve disc 14 during the opening and closing process, thus enhancing the sealing effect. The first sealing ring 34 is fastened to the first eccentric block 31, forming a multi-point sealing structure to prevent fluid leakage. The second sealing ring 35 is fastened to the valve disc 14, forming a sealing interface in the contact area between the valve disc 14 and the first eccentric block 31. The first eccentric hydraulic cylinder 36 and the second eccentric hydraulic cylinder 37 are respectively connected to the first and second eccentric blocks 32 for transmission. The position and fit of the valve disc 14 are further fine-tuned by hydraulically driving the eccentric block. During control, the eccentric hydraulic cylinder pushes or pulls the eccentric block, causing a slight eccentricity in the valve disc 14, thereby achieving higher sealing performance. Utilizing the sliding connection between the eccentric blocks and the driving force of the hydraulic cylinder, efficient sealing is maintained throughout the opening and closing process. Through multi-stage eccentric coordination, the valve achieves excellent sealing performance and pressure resistance, reducing wear and extending service life. Secondly, the first cleaning block 21 and the second cleaning block 22 move or rotate under the drive of the cleaning motor 23 to clean the valve body 11. Inside the valve body 11 and on the surface of the valve disc 14, the cleaning motor 23 is fastened to the valve body 11 and driven by the transmission assembly 24 to provide power to the cleaning blocks. The transmission assembly 24 transmits the power of the cleaning motor 23 to the first cleaning block 21 and the second cleaning block 22 respectively, achieving coordinated cleaning. The first flow stabilizing groove 212 (located on the first cleaning block 21) and the second flow stabilizing groove 221 (located on the second cleaning block 22) are both spiral-shaped and interconnected, which can guide the fluid or cleaning liquid to flow along the spiral path. The cleaning chamber 211 (located in the first cleaning block 21) and the connecting chamber 222 (located in the second cleaning block 22) are both spiral-shaped and interconnected, which can guide the fluid or cleaning liquid to flow along the spiral path. The cleaning blocks 22 have hemispherical and cylindrical structures that are connected to each other. They are used to store cleaning fluid or collect dirt. They work in conjunction with the flow stabilizing groove to improve the cleaning effect. The cleaning motor 23 is fixed on the valve body 11. The output power is distributed to the two cleaning blocks through the transmission component 24, so that they rotate or reciprocate at corresponding positions inside and outside the valve body 11. A continuous and stable fluid channel is formed through the spiral flow stabilizing groove. The structural advantages of the cleaning chamber 211 and the connecting chamber 222 are used to carry away or collect dirt, ensuring that the valve can still maintain a good condition after long-term use and reducing failures or performance degradation caused by dirt accumulation.
