Description

Technical Field

[0001] This utility model relates to the field of valves, and provides a valve assembly, a fluid handling system, and a rail vehicle. Background Technology

[0002] In industrial production processes, fluid regulation and control are primarily achieved through ball valves. Ball valves control fluid flow by rotating a ball-shaped opening and closing element around its axis, driven by the valve stem. While ball valves are widely used due to their high efficiency and reliability, their drawbacks are becoming increasingly apparent in certain advanced applications. Firstly, ball valves lack aesthetic appeal, which may negatively impact customer perception in applications where product appearance and brand image are important. Secondly, ball valves occupy a relatively large area, causing inconvenience in installation and maintenance for applications with tight space constraints and high requirements.

[0003] To address these issues, alternative products such as electric valves and butterfly valves have emerged on the market. These products, while meeting flow control requirements, also prioritize optimized appearance and installation space. However, their adjustment accuracy and flow control performance are often inferior to ball valves, representing a certain degree of performance compromise. Furthermore, existing alternative products may struggle to maintain high reliability and durability in harsh industrial environments, failing to fully meet the demanding requirements of industrial applications.

Detailed Implementation

[0033] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0034] like Figures 1 to 3 As shown, a first aspect embodiment of the present invention provides a valve assembly, comprising:

[0035] The housing 100 has a first channel 102 for fluid flow, and a stop surface 104 is formed on the inner wall of the first channel 102.

[0036] The movable body 106 is movably disposed within the housing 100. A second channel 108 for fluid flow is formed within the movable body 106. A first through hole 110 is provided on the movable body 106 to fluidly communicate with the second channel 108. The movable body 106 is adapted to switch between a first position and a second position relative to the housing 100. In the first position, the stop surface 104 is adapted to shield the first through hole 110. In the second position, the first channel 102 and the second channel 108 are fluidly connected through the first through hole 110.

[0037] According to the valve assembly provided in the first aspect of this utility model, by switching the movable body 106 between a first position and a second position, the valve assembly of this utility model can flexibly control the flow state of the medium and realize the functions of opening and closing. This design makes the valve assembly have broad application prospects in fluid control systems. Moreover, by adjusting the position of the movable body 106 relative to the housing 100, the flow rate of the fluid flowing through the first through hole 110 can be flexibly adjusted, thereby achieving precise regulation of the fluid flow rate. Due to the compact design of the movable body 106 and the housing 100, the overall valve assembly is relatively small in size, making it easy to install and integrate into various fluid control systems. This helps to reduce the overall space occupied by the system and improve the overall performance of the system. Through precise machining and assembly processes, the fit between the movable body 106 and the housing 100 is ensured to be tight and stable. This allows the valve assembly to maintain good sealing performance and fluid control capability during long-term use, improving the reliability and stability of the system. The design of the valve assembly makes the disassembly and replacement of the movable body 106 relatively simple and convenient. This helps to reduce the maintenance cost and time of the system and improve the maintenance efficiency of the system. Therefore, the valve assembly provided by the first aspect of this utility model has the advantages of flexible fluid control, compact structure, high reliability and easy maintenance, and is suitable for various fluid control systems that require precise control of the flow of media.

[0038] Please continue reading Figures 1 to 3The first aspect of this utility model provides a valve assembly design, the core components of which include a housing 100 and a movable body 106.

[0039] The housing 100 serves as the basic structure of the valve assembly, and its interior contains a first channel 102, which is the main path for the flow of media (such as fluid). A stop surface 104 is designed on the inner wall of the first channel 102 of the housing 100. This stop surface 104 plays a crucial control role in the operation of the valve assembly, controlling the flow rate of the media.

[0040] The movable body 106 is another key component movably disposed within the housing 100. A second channel 108 is formed inside the movable body 106, which also serves for fluid flow. A first through-hole 110 is also specifically provided on the movable body 106, which is in fluid communication with the second channel 108. This first through-hole 110 acts as a bridge, allowing fluid communication between the first channel 102 and the second channel 108 when the movable body 106 is in a specific position.

[0041] In this embodiment of the invention, the movable body 106 is designed to switch between a first position and a second position relative to the housing 100. When the movable body 106 is in the first position, the stop surface 104 inside the housing 100 blocks the first through hole 110 on the movable body 106, thereby blocking the fluid communication between the first channel 102 and the second channel 108. When the movable body 106 is moved to the second position, the stop surface 104 no longer blocks the first through hole 110, and at this time, the first channel 102 and the second channel 108 are fluidly connected through the first through hole 110.

[0042] Understandably, during the transition of the movable body 106 from the first position to the second position, the flow rate of the fluid flowing through the first through-hole 110 gradually increases until the movable body 106 is in the second position, at which point the flow rate of the fluid flowing through the first through-hole 110 reaches its maximum value. Conversely, during the transition of the movable body 106 from the second position to the first position, the flow rate of the fluid flowing through the first through-hole 110 gradually decreases until the movable body 106 is in the first position, at which point the flow rate of the fluid flowing through the first through-hole 110 is zero.

[0043] According to one embodiment of the present invention, the first channel 102 includes:

[0044] Exit section 112;

[0045] The connecting section 114 is connected to the outlet section 112. The stop surface 104 is formed between the connecting section 114 and the outlet section 112. From the connecting section 114 to the outlet section 112, the stop surface 104 approaches the center line of the connecting section 114.

[0046] In this embodiment of the invention, the first channel 102 mainly consists of two parts: an outlet section 112 and a connecting section 114. These two parts are structurally interconnected, ensuring smooth transmission of gas or fluid. Specifically, a stop surface 104 is formed between the connecting section 114 and the outlet section 112. This stop surface 104 gradually changes direction from the connecting section 114 to the outlet section 112, characterized by its proximity to the centerline of the connecting section 114.

[0047] Specifically, when gas or fluid flows from the connecting section 114 into the outlet section 112, it encounters this stop surface 104 that gradually approaches the centerline. This design not only helps guide the fluid to change direction more smoothly, but also reduces turbulence and energy loss that may occur when the fluid changes direction. In addition, the presence of the stop surface 104 increases the structural strength of the channel, improving its overall durability and service life.

[0048] The design of the stop surface 104 facilitates a smoother transition of fluid between the connecting section 114 and the outlet section 112, reducing turbulence and energy loss, thereby improving overall fluid transmission efficiency. By cleverly designing the stop surface 104, the structural strength of the channel can be increased without adding extra material, making it more durable and extending its service life. The presence of the stop surface 104 allows for more precise control of fluid flow direction and velocity, helping to meet the fluid control requirements of specific application scenarios. While the design of the stop surface 104 increases the complexity of the channel to some extent, it also provides opportunities for optimizing the manufacturing process. For example, by employing advanced processing techniques, this inclined surface can be manufactured more precisely, thereby improving the manufacturing accuracy and consistency of the channel. Therefore, by introducing the stop surface 104, this invention not only improves fluid transmission efficiency but also enhances the structural strength of the channel, optimizes fluid control, and simplifies the manufacturing process.

[0049] According to one embodiment of the present invention, a mating surface 116 adapted to the shape of the stop surface 104 is formed on the movable body 106, and a first through hole 110 is formed on the mating surface 116.

[0050] In this embodiment of the invention, a mating surface 116 is specially designed on the movable body 106 to perfectly match the shape of the stop surface 104. This design not only ensures a tight fit between the movable body 106 and the component containing the stop surface 104, but also improves the stability and reliability of the overall structure. More importantly, the first through hole 110 is formed on the mating surface 116, and this layout further optimizes the fluid transmission path and improves transmission efficiency.

[0051] Specifically, the shape, inclination angle, and dimensions of the mating surface 116 are precisely calculated and designed based on the corresponding parameters of the stop surface 104. This precise fit ensures that when the moving body 106 is combined with the component containing the stop surface 104, the gap between them is minimized, thereby reducing the possibility of fluid leakage. At the same time, the location of the first through hole 110 on the mating surface 116 is also carefully planned to ensure that the fluid can pass smoothly and is not excessively obstructed during transmission.

[0052] The tight fit between the mating surface 116 and the stop surface 104 significantly improves the overall sealing performance of the structure and reduces the risk of fluid leakage. This is especially important in applications requiring strict control of fluid flow. The location of the first through hole 110 on the mating surface 116 is carefully planned to ensure smooth fluid flow and maintain high speed and pressure during transmission. This helps improve the efficiency and stability of fluid transmission. The design of the mating surface 116 not only improves the fitting accuracy between the moving body 106 and the component containing the stop surface 104, but also enhances the stability of the overall structure. This design makes the entire structure more robust and durable under external forces, less prone to deformation or damage. Due to the precise fit between the mating surface 116 and the stop surface 104, the installation between the moving body 106 and the component containing the stop surface 104 becomes simpler and faster. At the same time, this design also facilitates subsequent maintenance and repair work, reducing maintenance costs and time costs. This invention improves fluid transmission efficiency, enhances sealing performance, and improves structural stability by forming a mating surface 116 on the movable body 106 that matches the shape of the stop surface 104, and by opening a first through hole 110 on the mating surface 116. These technical effects together give this invention higher performance and better adaptability in practical applications.

[0053] According to one embodiment of the present invention, a plurality of first through holes 110 are provided at intervals on the mating surface 116 along the circumference of the movable body 106.

[0054] In this embodiment of the invention, the design of the movable body 106 has been further optimized. Specifically, a plurality of first through holes 110 are spaced apart on the mating surface 116 along the circumference of the movable body 106. This design not only improves the flow capacity of fluid through the movable body 106, but also enhances the uniformity and stability of the overall structure.

[0055] Specifically, the mating surface 116, as a key part of the moving body 106 that closely mates with the stop surface 104, has a carefully planned layout of multiple first through holes 110. These first through holes 110 are evenly distributed along the circumference of the moving body 106, ensuring that the fluid maintains a uniform flow velocity and pressure distribution when passing through the moving body 106. At the same time, the location and number of the first through holes 110 are also precisely calculated based on the fluid flow rate and pressure requirements in the actual application scenario to meet specific fluid control requirements.

[0056] By creating multiple first through holes 110 at intervals on the mating surface 116, the flow capacity of fluid through the moving body 106 is significantly improved. This design allows fluid to pass through the moving body 106 more smoothly, reducing obstruction and energy loss during transmission. The uniform distribution of the first through holes 110 not only improves the uniformity of fluid transmission but also enhances the uniformity and stability of the overall structure of the moving body 106. This design allows the moving body 106 to distribute stress more evenly when subjected to fluid pressure and external forces, thereby improving overall durability and service life. The location and number of the multiple first through holes 110 can be precisely adjusted according to the fluid flow and pressure requirements in the actual application scenario, thereby achieving precise control of fluid flow. This design enables the valve assembly to maintain stable performance under different operating conditions, improving overall reliability and adaptability. By employing advanced processing technology and processes, the multiple first through holes 110 on the mating surface 116 can be ensured to have precise dimensional, positional, and shaped consistency. This helps improve the overall manufacturing precision and consistency of the valve assembly, thereby ensuring that each valve assembly has the same performance and quality. This invention improves fluid flow capacity, enhances structural uniformity and stability, and optimizes fluid control by creating multiple first through holes 110 at intervals on the mating surface 116 of the moving body 106. These technical effects collectively result in higher performance and better adaptability of this invention in practical applications.

[0057] According to one embodiment of the present invention, the spacing between two adjacent first through holes 110 is equal.

[0058] In this embodiment of the invention, the plurality of first through holes 110 formed on the mating surface 116 are arranged at equal intervals. This evenly spaced arrangement not only improves the uniformity of fluid flow through the moving body 106, but also further enhances the stability and reliability of the overall structure.

[0059] Specifically, the evenly spaced arrangement of the first through holes 110 ensures that the fluid experiences more uniform resistance when passing through the moving body 106, thereby reducing fluctuations and instability during fluid transmission. Simultaneously, the evenly spaced design also helps improve the uniformity of the overall structure of the moving body 106, resulting in a more rational distribution of stress within the structure and preventing excessive localized stress.

[0060] The equidistant arrangement of adjacent first through holes 110 allows for a more uniform flow velocity and pressure distribution when the fluid passes through the moving body 106, reducing fluctuations and instability during transmission, thereby improving the uniformity and stability of fluid transmission. The equidistant arrangement of the first through holes 110 enhances the uniformity of the overall structure of the moving body 106, resulting in a more rational stress distribution. This design helps avoid excessive local stress, thus improving the durability and service life of the moving body 106. The equidistant arrangement of the first through holes 110 allows the valve assembly to maintain more stable performance when controlling fluid flow. This design facilitates precise control of fluid flow, improving the reliability and adaptability of the valve assembly. By employing advanced processing techniques and processes, precise dimensional consistency in the spacing between adjacent first through holes 110 can be ensured. This helps improve the overall manufacturing precision and consistency of the valve assembly, ensuring that each valve assembly has the same performance and quality. This invention achieves improved fluid transmission uniformity, enhanced structural stability, and optimized fluid control by arranging multiple first through holes 110 at equal intervals on the mating surface 116 of the moving body 106. These technical effects combined enable the invention to have higher performance and better adaptability in practical applications, providing new ideas and methods for the design and optimization of fluid control systems.

[0061] According to one embodiment of the present invention, a first internal thread segment 118 is formed on the connecting segment 114, and a first external thread segment 120 and a second external thread segment 122 are provided at intervals on the movable body 106 along the axial direction of the second channel 108. In a first position, the first internal thread segment 118 and the first external thread segment 120 are engaged, and in a second position, the first internal thread segment 118 and the second external thread segment 122 are engaged.

[0062] In this embodiment of the invention, a first internal thread segment 118 is formed on the connecting segment 114, while a first external thread segment 120 and a second external thread segment 122 are provided at intervals on the movable body 106 along the axial direction of the second channel 108. This design allows the movable body 106 to be securely threadedly connected to the connecting segment 114 in two different positions (i.e., the first position and the second position).

[0063] In the first position, the first external threaded section 120 of the movable body 106 engages with the first internal threaded section 118 of the connecting section 114, achieving an initial connection between the movable body 106 and the connecting section 114. This connection state is used for initial installation, commissioning, or certain specific operating modes.

[0064] In the second position, the movable body 106 engages with the first internal thread section 118 of the connecting section 114 via its second external thread section 122. This transition is typically achieved by axial movement of the movable body 106 relative to the connecting section 114, in order to adjust the state of the fluid passage, change the opening and closing degree of the valve, or achieve other specific functional requirements.

[0065] The double-threaded connection mechanism provides a more robust connection between the moving part 106 and the connecting section 114, reducing the risk of loosening or leakage due to vibration, impact, or fluid pressure fluctuations. Switching between the first and second positions offers more functional options for the valve or fluid control system. For example, the flow rate and pressure of the fluid can be adjusted by changing the position of the moving part 106, achieving finer fluid control. While this design increases structural complexity, the standardized threaded connection keeps installation and maintenance relatively simple. Simultaneously, the double-threaded connection mechanism provides a reliable locking method, reducing failures caused by improper installation or maintenance negligence. The threaded connection results in a larger and more evenly distributed contact area between the moving part 106 and the connecting section 114, improving overall durability and service life. This design can adapt to the needs of various fluid control systems and operating environments. Whether dealing with high pressure, high temperature, or corrosive fluids, specific application requirements can be met by adjusting the thread material, size, and engagement depth. This invention, by proposing a design for a movable body 106 and a connecting section 114 with a double-threaded connection mechanism, achieves enhanced connection stability, improved versatility, simplified installation and maintenance, and increased durability and adaptability. These combined technical effects result in higher performance and better adaptability in practical applications, providing new ideas and methods for the design and optimization of fluid control systems.

[0066] According to one embodiment of the present invention, it further includes an end connector 124, which is connected to the movable body 106.

[0067] In this embodiment of the invention, a new component, the end connector 124, is introduced and designed to connect with the movable body 106. This design not only enriches the diversity and flexibility of the overall structure but also provides more connection options and functional expansion for the fluid control system.

[0068] Specifically, the end connector 124 is designed to fit tightly with the movable body 106 and is fixed to the movable body 106 by an appropriate connection method (such as threaded connection, welding, snap-fit, etc.). This connection not only ensures the stability between the movable body 106 and the end connector 124, but also allows them to function as a whole in the fluid control system.

[0069] The shape, size, and material of the end connector 124 can be customized to meet the needs of the specific application scenario. For example, it can be designed to fit with specific pipes, flanges, or other fluid control components to achieve seamless connection and continuity of fluid transmission.

[0070] By introducing the end connector 124, the connection options for the moving body 106 are greatly expanded. This allows the fluid control system to be flexibly configured to adapt to different working environments and fluid characteristics according to specific needs. The connection between the end connector 124 and the moving body 106 not only increases the overall structural stability but also improves the system's pressure resistance and durability. This is particularly important for working scenarios that require exposure to high-pressure, high-temperature, or corrosive fluids. The design of the end connector 124 typically takes into account ease of installation and simplicity of maintenance. For example, it can adopt standardized connection methods, making the installation process faster and more accurate; at the same time, it can be designed with an easily disassembled structure to facilitate subsequent maintenance and repair work. The design of the end connector 124 can also further optimize the fluid transmission path, reducing fluid resistance and energy loss during transmission. This helps improve the efficiency and stability of fluid transmission, thereby meeting specific fluid control requirements. By selecting a suitable end connector 124, additional functions can be added to the fluid control system without changing the structure of the moving body 106 itself. For example, sensors, actuators, or other control elements can be added to achieve real-time monitoring and precise control of fluid flow. This invention introduces a novel component, the end connector 124, and connects it to the movable body 106. This increases connection flexibility, improves overall structural strength, simplifies installation and maintenance, optimizes fluid transmission, and enhances functional expandability. These combined effects result in higher performance and better adaptability in practical applications, providing new ideas and methods for the design and optimization of fluid control systems.

[0071] According to one embodiment of the present invention, the end connector 124 is provided with a second internal thread section 126, and part of the second internal thread section 126 engages with the second external thread section 122.

[0072] In this embodiment of the invention, the design of the second internal thread segment 126 on the end connector 124 and its meshing relationship with the second external thread segment 122 on the movable body 106 are described. Specifically, the design provides a second internal thread segment 126 on the inner surface of the end connector 124, and a portion of the second internal thread segment 126 meshes with the second external thread segment 122 on the movable body 106, which is axially arranged along the second channel 108.

[0073] This design not only further enhances the connection stability between the moving body 106 and the end connector 124, but also provides an additional locking mechanism to prevent loosening or leakage due to vibration, impact, or fluid pressure fluctuations. Simultaneously, by adjusting the engagement length and tightness of the second internal thread section 126 and the second external thread section 122, fine adjustments to the fluid channel state can be achieved, such as changing the fluid flow rate, pressure, or direction.

[0074] The engagement of the second internal thread section 126 and the second external thread section 122 strengthens the connection between the moving body 106 and the end connector 124, enabling it to withstand greater tensile and torque forces and reducing the risk of loosening or detachment due to external forces. The engaging threaded structure creates multiple sealing points on the contact surface, effectively preventing fluid leakage at the connection. This is particularly important in applications requiring strict fluid flow control, such as high-pressure, high-temperature, or corrosive fluid environments. Fine adjustments to the engagement length and tightness of the second internal thread section 126 and the second external thread section 122 allow for precise control of the fluid flow path. This adjustment can meet various fluid control needs, such as changing the flow rate, pressure, or direction of the fluid, thereby improving the flexibility and adaptability of the fluid control system. Although an additional threaded connection structure is introduced, the standardized thread design and manufacturing process make installation and maintenance relatively simple and quick. Furthermore, the reliability of the threaded connection reduces the failure rate caused by improper installation or maintenance negligence. The engagement of the second internal thread section 126 and the second external thread section 122 not only enhances the connection strength between the moving body 106 and the end connector 124, but also improves the structural strength of the entire fluid control system. This allows the system to better withstand the effects of the external environment and internal fluids, extending its service life. By introducing the engagement design of the second internal thread section 126 and the second external thread section 122, this invention achieves enhanced connection stability, improved sealing performance, fine adjustment of the fluid channel state, simplified installation and maintenance, and improved overall structural strength. These technical effects collectively give this invention higher performance and better adaptability in practical applications, providing new ideas and methods for the design and optimization of fluid control systems.

[0075] According to one embodiment of the present invention, a second through hole 128 is provided at the end of the housing 100 along the axial direction of the housing 100.

[0076] In this embodiment of the invention, a second through hole 128 is formed at the end of the housing 100 along its axial direction. This design aims to optimize the gas discharge function in the fluid control system, especially when it is necessary to remove gas accumulated inside the system or to perform pressure balance regulation.

[0077] The location of the second through-hole 128 was carefully planned to ensure that it can effectively cooperate with other components in the fluid control system (such as the moving body 106, the end connector 124, etc.) to achieve smooth gas discharge. At the same time, the size and shape of the second through-hole 128 have also been optimized according to the needs of the actual application scenario to ensure that it can meet specific discharge efficiency and pressure requirements.

[0078] By opening a second through-hole 128 at the end of the housing 100, effective gas discharge from the system is achieved. This helps prevent gas accumulation in the system, thereby improving the continuity and stability of fluid flow. The design of the second through-hole 128 also enhances the fluid control system's ability to balance pressure changes. When the internal pressure of the system increases, gas can be quickly discharged through the second through-hole 128, thus maintaining stable system operation. By optimizing gas discharge and pressure balancing functions, the design of the second through-hole 128 improves the overall reliability of the fluid control system. This reduces system failures and downtime caused by gas accumulation or pressure imbalance. The design of the second through-hole 128 can be customized according to the needs of actual application scenarios. For example, in applications requiring precise control of fluid flow or high-pressure fluid transmission, specific performance requirements can be met by adjusting the size and position of the second through-hole 128. The presence of the second through-hole 128 also simplifies the maintenance of the fluid control system. Regular inspection and cleaning of the second through-hole 128 ensures smooth system operation and extends its service life. This invention optimizes gas emission, improves pressure balancing, enhances system reliability, and expands adaptability to various application scenarios by creating a second through hole 128 along the axial direction at the end of the housing 100. These combined effects result in higher performance and better adaptability in practical applications, providing new ideas and methods for the design and optimization of fluid control systems.

[0079] According to one embodiment of the present invention, there are multiple second through holes 128, and the multiple second through holes 128 are arranged at intervals along the circumference of the housing 100.

[0080] In this embodiment of the invention, a plurality of second through holes 128 are arranged at circumferential intervals along the housing 100. This design aims to further improve the efficiency and uniformity of gas discharge in the fluid control system, ensuring that the gas inside the system can be discharged quickly and smoothly.

[0081] Multiple second through holes 128 are distributed circumferentially along the housing 100, ensuring uniform gas distribution during emission and preventing localized gas accumulation or poor emission. This design also enhances the system's flexibility in responding to changes in direction and pressure, allowing gas to be emitted from multiple directions as needed.

[0082] The design of multiple second through-holes 128 allows for faster gas discharge from the system, improving gas discharge efficiency. This helps reduce the impact of gas accumulation on fluid flow, thereby improving system stability and performance. The multiple second through-holes 128 spaced circumferentially along the housing 100mm ensure uniform gas distribution during discharge, avoiding localized gas accumulation. This uniformity contributes to improved fluid flow continuity and stability, thus optimizing overall system performance. The design of multiple second through-holes 128 enhances the system's flexibility in responding to changes in direction and pressure. Regardless of the gas's origin or internal pressure variations, discharge can occur through the multiple second through-holes 128, maintaining stable system operation. By strategically arranging the multiple second through-holes 128, the structure of the fluid control system can be further optimized. This design not only improves the system's gas discharge capacity but also helps reduce system complexity and maintenance costs. The design of multiple second through-holes 128 can be customized to meet specific application requirements. For example, in applications requiring large-volume gas discharge or high-pressure fluid transmission, the number and size of the second through-holes 128 can be increased to meet specific performance requirements. This invention, by employing a design with multiple second through holes 128 spaced circumferentially along the housing 100, achieves improved gas emission efficiency, enhanced emission uniformity, increased system flexibility, and optimized system structure. These combined effects result in higher performance and better adaptability in practical applications, providing new ideas and methods for the design and optimization of fluid control systems.

[0083] According to one embodiment of the present invention, the spacing between two adjacent second through holes 128 is equal.

[0084] In this embodiment of the invention, for the plurality of second through holes 128 spaced circumferentially along the housing 100, special emphasis is placed on ensuring that the spacing between two adjacent second through holes 128 is equal. This equidistant design not only helps to ensure the uniformity and efficiency of gas emission, but also improves the overall aesthetics and structural stability of the fluid control system.

[0085] By arranging the second through holes 128 at equal intervals, it can be ensured that the gas can flow out evenly from all directions during the discharge process, avoiding local gas accumulation or poor discharge. At the same time, the equal-interval design also helps to reduce the vibration and noise generated by the fluid control system during operation, improving the stability and reliability of the system.

[0086] Furthermore, the equally spaced second through-holes 128 make the structure of the fluid control system more balanced and aesthetically pleasing. This design not only meets engineering aesthetic requirements but also helps reduce system complexity and manufacturing costs.

[0087] The equally spaced second through-holes 128 allow for more uniform gas discharge, improving emission efficiency and system stability. This helps reduce the impact of gas accumulation on fluid flow and optimizes the overall system performance.

[0088] Improving Structural Stability: The equidistant arrangement of the second through holes 128 enhances the structural stability of the fluid control system. By uniformly distributing the second through holes 128, vibration and noise generated during system operation can be reduced, extending the system's service life. The equidistant design of the second through holes 128 makes the fluid control system more balanced and aesthetically pleasing. This design meets engineering aesthetic requirements and helps improve the overall quality and market competitiveness of the product. The equidistant design of the second through holes 128 simplifies the manufacturing process and reduces production costs. Standardized production processes and techniques facilitate large-scale production and quality control. The equidistant design of the second through holes 128 can be customized according to the needs of actual application scenarios. For example, in applications requiring the handling of large gas emissions or high-pressure fluid transmission, the number and size of the second through holes 128 can be adjusted to meet specific performance requirements while maintaining an equidistant design to optimize the overall system performance. This invention, by employing a design with equal spacing between adjacent second through holes 128, achieves optimized gas emissions, improved structural stability, enhanced aesthetics, and reduced manufacturing costs. These technical effects combined enable the invention to have higher performance and better adaptability in practical applications, providing new ideas and methods for the design and optimization of fluid control systems.

[0091] The fluid inlet serves as the fluid entry point into the system and is in fluid communication with the second channel 108. It is responsible for receiving fluid from the outside or upstream and guiding it to the valve assembly for further processing or control.

[0092] The fluid outlet serves as the outlet for the fluid leaving the system and is in fluid communication with the first channel 102. It is responsible for outputting the fluid, after being processed or controlled by the valve assembly, to external or downstream equipment.

[0093] When fluid enters the second channel 108 from the fluid inlet, the flow rate, flow volume, and other parameters of the fluid can be adjusted by changing the position of the movable body 106 relative to the housing 100. After being processed by the valve assembly, the fluid eventually flows to the fluid outlet and is output to external or downstream equipment through the first channel 102. At this point, the fluid's state (such as pressure, flow rate, temperature, etc.) has been adjusted and controlled as needed.

[0094] Through integrated valve assembly design, this system enables precise control and regulation of fluids, thereby improving the efficiency and quality of fluid processing. The flexible control of the valve assembly allows the system to adapt to different fluid processing needs, enhancing its flexibility and adaptability. Optimizing the design and layout of the valve assembly reduces system complexity and manufacturing costs while improving system reliability and service life. Precise valve assembly control helps prevent fluid leakage and accidents, thus enhancing system safety. Therefore, the fluid processing system provided in the second aspect of this invention has advantages such as high efficiency, flexibility, low cost, and high safety, making it suitable for various fluid processing and control applications.

These systems achieve precise control and regulation of fluids through valve assemblies or fluid handling systems to ensure stable operation of the rail vehicle under various working conditions.

[0098] The valve assembly design allows for flexible switching of fluid between different channels, meeting the fluid control requirements of rail vehicles at different operating stages. The fluid handling system, by integrating multiple valves and control elements, achieves functions such as fluid diversion, confluence, pressure regulation, and flow control, further improving the fluid control efficiency of rail vehicles.

[0099] By integrating valve assemblies or fluid handling systems, rail vehicles can achieve precise control and regulation of fluids, thereby improving the efficiency and quality of fluid control. This helps optimize the power, braking, and cooling performance of rail vehicles, enhancing overall operational efficiency. The introduction of valve assemblies or fluid handling systems makes the fluid control system of rail vehicles more complex and sophisticated, but also improves system reliability and stability. Precise control of valve opening and closing allows for fine-tuning of fluids, preventing system failures or safety accidents caused by improper fluid control. The modular design of valve assemblies or fluid handling systems facilitates maintenance and replacement. When a system failure occurs, the problem can be quickly located and repaired, reducing maintenance costs and time. Precise fluid control helps prevent fluid leaks and accidents, thus improving rail vehicle safety. Especially in braking and cooling systems, precise control of valve assemblies or fluid handling systems ensures rapid vehicle response in emergencies, reducing the risk of accidents.
