Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, and more specifically, to a multi-way ball valve. Background Technology

[0002] A multi-way ball valve is a type of valve used in piping systems to control the flow rate, pressure, and direction of fluids. It achieves this through a ball with multiple channels. Compared to traditional two-way ball valves, multi-way ball valves offer more complex fluid control solutions and are suitable for various industrial applications. However, existing ball valves suffer from difficulties in quick installation, often requiring significant time and effort. Furthermore, the multiple channels of a multi-way ball valve necessitate repeated adjustments and alignments during installation, increasing the operational complexity. Due to the complexity of the installation process, the error rate is relatively high. Common installation errors include inaccurate alignment of the ball with the pipe, which not only affects the valve's performance but may also necessitate reinstallation, leading to unnecessary waste.

[0003] Therefore, there is an urgent need for a multi-way ball valve to solve the problems existing in the current technology. Utility Model Content

[0004] In view of this, the present invention proposes a multi-way ball valve, which aims to solve the problem of the complicated installation process of existing ball valves.

[0005] This utility model provides a multi-way ball valve, comprising:

[0006] The ball valve body includes a valve housing, a rotating device, and a ball. The valve housing is connected to a first water pipe and a second water pipe at multiple ends. The ball is disposed inside the valve housing and is rotatably connected to the rotating device.

[0007] The limiting unit includes a docking part and a snap-fit ​​part. The snap-fit ​​part is disposed on the first water pipe, and the docking part is disposed on the second water pipe. The docking part and the snap-fit ​​part snap-fit ​​each other. The first water pipe and the second water pipe are snap-fitted together through the snap-fit ​​part and the docking part.

[0008] The sealing unit is inserted into the first water pipe.

[0009] Furthermore, the snap-fit ​​part includes a first limiting ring and a first limiting hole. The first limiting ring is disposed at one end of the first water pipe, and a plurality of first limiting holes are provided on the first limiting ring.

[0010] Furthermore, the sealing part includes a first sealing gasket, a first sealing groove, and a first sealing ring. The top of the first sealing gasket is fixedly connected to the first sealing ring, and the first sealing groove is equidistantly disposed on the outside of the first sealing ring.

[0011] Furthermore, the docking part includes a first pair of connecting pipes, a second limiting ring, and a fastening part. The first pair of connecting pipes is fixedly connected inside the second heat exchange tube. The fastening part is provided at the front end of the first pair of connecting pipes, and the second limiting ring is provided at the lower end of the fastening part. The second limiting ring is used to prevent the fastening part from falling off.

[0012] Furthermore, the fastening part includes a first fastener, a second fastener, and a fastening strip. The outer side of the first fastener has through holes arranged in a ring at equal intervals. The through holes penetrate the first fastener. The second fastener is inserted into the through holes. The top of the second fastener penetrates the through holes. The fastening strip is provided at the bottom of the second fastener. The fastening strip is used to limit the position of the second fastener.

[0013] Furthermore, the rotating device includes a valve stem, a rotating wheel, and a connecting sleeve. The valve housing is provided with a connecting sleeve, the valve stem is located inside the valve housing, and its top passes through the connecting sleeve to connect with the rotating wheel.

[0014] Furthermore, the ball valve body also includes a sealing ring, which is disposed between the ball and the first water pipe.

[0015] Furthermore, it also includes a filtration device, which is disposed on one side of the sealing unit and is used to filter impurities in the fluid.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0028] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] See Figure 1 As shown, this embodiment provides a multi-way ball valve, including: a ball valve body, including a valve housing 1, a rotating device and a ball 2, wherein the valve housing 1 is connected to a first water pipe 5 and a second water pipe 6 at multiple ends, and the ball 2 is disposed inside the valve housing 1 and is rotatably connected to the rotating device;

[0030] The limiting unit 3 includes a docking part 301 and a snap-fit ​​part 302. The snap-fit ​​part 302 is disposed on the first water pipe 5, and the docking part 301 is disposed on the second water pipe 6. The docking part 301 and the snap-fit ​​part 302 snap-fit ​​each other. The first water pipe 5 and the second water pipe 6 are snap-fitted together by the snap-fit ​​part 302 and the docking part 301.

[0031] The sealing unit 4 is inserted into the first water pipe 5.

[0032] Specifically, the valve body 1 of the multi-way ball valve has multiple ports, each of which is fixedly connected to a first water pipe 5. The first water pipe 5 is provided with a snap-fit ​​part 302, and the second water pipe 6 is provided with a butt joint part 301. The first water pipe 5 is a short pipe, and the second water pipe 6 is a fluid passage pipe. When it is necessary to seal and fix the first water pipe 5 and the second water pipe 6, the butt joint part 301 and the snap-fit ​​part 302 can be used to cooperate with each other to complete the sealing and fixing. At the same time, the sealing unit 4 inside the first water pipe 5 can further ensure the sealing effect of the first water pipe 5 and the second water pipe 6.

[0033] Understandably, traditional multi-way ball valves require precise alignment of each channel and pipe during installation, which is not only time-consuming and labor-intensive but also prone to installation errors. However, by incorporating snap-fit ​​parts 302 and mating parts 301 on the first water pipe 5 and the second water pipe 6 respectively, the installation process becomes simple and quick. Installers simply align and snap the snap-fit ​​part 302 of the first water pipe 5 with the mating part 301 of the second water pipe 6 to quickly achieve a seal. This plug-and-play feature significantly shortens installation time, reduces human error during installation, and improves overall installation efficiency and reliability. The simplified installation process not only saves time and manpower but also reduces installation costs. The installation of traditional multi-way ball valves often requires high-precision measuring tools and specialized equipment, increasing the investment cost of equipment and tools. In contrast, the ease of installation of multi-way ball valves reduces reliance on high-precision measuring tools and specialized equipment, thus lowering the investment in installation tools and equipment.

[0034] The limiting unit 3, through the cooperation of the snap-fit ​​part 302 and the docking part 301, ensures a tight connection between the first water pipe 5 and the second water pipe 6, thereby improving the sealing performance. The sealing performance of traditional multi-way ball valves mainly relies on the precise alignment of the ball 2 and the sealing ring 7. The addition of an extra sealing point between the first water pipe 5 and the second water pipe 6 further reduces the risk of leakage. The sealing unit 4 is inserted into the first water pipe 5, further ensuring the sealing effect between the first water pipe 5 and the second water pipe 6. This double sealing not only improves the reliability of the seal but also forms an additional barrier between the ball 2 and the sealing ring 7, reducing the possibility of external impurities entering the valve. This not only extends the valve's service life but also improves its reliability and stability under complex operating conditions. Due to its simple installation process and reliable sealing performance, the multi-way ball valve is also more convenient for maintenance and repair. Traditional multi-way ball valves often require the disassembly of multiple components during maintenance, which is complex and prone to errors. However, in this embodiment, when components need to be disassembled or replaced, disassembly can be quickly completed simply by separating the snap-fit ​​part 302 from the docking part 301. Maintenance personnel can complete repairs and replacements in a short time, reducing manpower and time costs during the maintenance process.

[0035] In some embodiments of this application, see Figure 2 , Figure 3 As shown, the snap-fit ​​part 302 includes a first limiting ring 3021 and a first limiting hole 3022. The first limiting ring 3021 is disposed at one end of the first water pipe 5, and a plurality of first limiting holes 3022 are provided on the first limiting ring 3021.

[0036] Specifically, the snap-fit ​​part 302 provided on the first water pipe 5 includes a first limiting ring 3021 and a first limiting hole 3022. The first limiting ring 3021 is provided on the outer surface of the end of the first water pipe 5 away from the heat exchange hole. The first limiting ring 3021 is provided with a plurality of first limiting holes 3022. The first limiting holes 3022 are used to cooperate with the docking part 301 to achieve the sealing and fixing of the first water pipe 5 and the second water pipe 6. The sealing part is provided inside the first water pipe 5. The sealing part is located below the first limiting ring 3021. When the second water pipe 6 is inserted into the first water pipe 5, the front end of the second water pipe 6 fits against the sealing unit 4.

[0037] Understandably, the quick sealing and fixing of the first water pipe 5 and the second water pipe 6 is achieved through the cooperation of the snap-fit ​​part 302 and the mating part 301. The installer only needs to align the front end of the second water pipe 6 with the first limiting hole 3022 on the first water pipe 5, and complete the installation with a simple insertion and rotation. This plug-and-play design not only simplifies the installation steps but also reduces installation time. Traditional multi-way ball valve installation requires high-precision measuring tools and specialized equipment to ensure accurate alignment of all components, while this design significantly reduces reliance on these tools and equipment, making the installation process simpler and more efficient. The first limiting ring 3021 and the first limiting hole 3022 ensure a tight connection between the first water pipe 5 and the second water pipe 6, improving sealing performance. When the second water pipe 6 is inserted into the first water pipe 5, its front end fits tightly against the sealing unit 4, forming a double sealing structure. In addition to the sealing provided by the ball 2 and the sealing ring 7, an additional sealing point is added between the first water pipe 5 and the second water pipe 6, further reducing the risk of leakage.

[0038] The sealing unit 4 is located below the first limiting ring 3021 and fits tightly against the front end of the second water pipe 6, further enhancing the valve's sealing reliability. This not only improves the sealing effect but also forms an additional barrier between the ball 2 and the sealing ring 7, reducing the possibility of external impurities entering the valve. This not only extends the valve's service life but also improves its reliability and stability under complex operating conditions. Due to its simple installation process and reliable sealing performance, this multi-way ball valve is also more convenient for maintenance and repair. Traditional multi-way ball valves often require the disassembly of multiple components when parts need to be removed or replaced, making the operation complex and prone to errors. However, with this multi-way ball valve, disassembly or replacement can be quickly completed simply by pulling the second water pipe 6 out of the first limiting hole 3022. Maintenance personnel can complete repairs and replacements in a shorter time, reducing manpower and time costs during maintenance. Furthermore, the sealing unit 4 also makes the replacement of the sealing ring 7 more convenient, further reducing maintenance difficulty.

[0039] In some embodiments of this application, see Figure 5As shown, the sealing part includes a first sealing gasket 410, a first sealing groove 420 and a first sealing ring 7430. The top of the first sealing gasket 410 is fixedly connected to the first sealing ring 7430, and the first sealing groove 420 is equidistantly disposed on the outer side of the first sealing ring 7430.

[0040] Specifically, the sealing part includes a first sealing gasket 410, a first sealing groove 420, and a first sealing ring 7430. In application, it is placed between the snap-fit ​​mechanism and the docking mechanism inside the first water pipe 5 and the second water pipe 6. The first sealing gasket 410 fits against the inside of the first water pipe 5 and the second water pipe 6 to achieve a preliminary seal. The first sealing ring 7430 is inserted into the groove inside the first water pipe 5, and its insertion into the first water pipe 5 can improve the sealing performance. The first sealing groove 420 and the first sealing ring 7430 on the outer surface of the first sealing ring 7430 fit and adhere to each other, further enhancing the overall sealing performance. The main body of the sealing ring 7 is composed of an elastic aerogel layer, a heat-resistant silicone layer, and a polyimide layer. The elastic aerogel layer ensures the stability and durability of the seal, the heat-resistant silicone layer makes the sealing ring 7 resistant to high temperature and not easy to age and deform, and the polyimide layer increases the strength and chemical corrosion resistance.

[0041] Understandably, sealing unit 4 improves the sealing performance of the multi-way ball valve through its multi-layer structure and interlocking seal. First, the first sealing gasket 410 fits tightly against the interior of the first water pipe 5 and the second water pipe 6, achieving an initial seal. Then, the first sealing ring 7430 is inserted into the internal groove of the first water pipe 5, further enhancing the seal's tightness. Finally, the interlocking design between the first sealing groove 420 and the first sealing ring 7430 creates a tighter sealing structure between the sealing rings 7. This multi-layer sealing design reduces the risk of fluid leakage and improves the overall sealing performance of the system by utilizing the synergistic effect of multiple sealing points, rather than relying on a single sealing point.

[0042] The first sealing ring 7430 is mainly composed of an elastic aerogel layer, a heat-resistant silicone layer, and a polyimide layer. Each of these layers plays a different role, working together to ensure the stability and durability of the seal. The elastic aerogel layer has excellent elasticity and pressure resistance, maintaining a stable seal during long-term valve operation and reducing seal failure caused by pressure changes. The heat-resistant silicone layer has excellent high-temperature resistance, able to withstand long-term operation in high-temperature environments, and is not prone to aging or deformation, ensuring the long service life of the sealing ring 7. The polyimide layer increases the strength and chemical corrosion resistance of the sealing ring 7, making it less susceptible to damage when in contact with chemical media, further improving the reliability and stability of the seal.

[0043] Sealing unit 4 is not only suitable for general operating conditions, but can also cope with various complex operating conditions such as high temperature, high pressure, and chemical corrosion. The pressure resistance of the elastic aerogel layer enables the valve to operate stably under high pressure, the high temperature resistance of the heat-resistant silicone layer enables the valve to work for a long time in high temperature environments, and the chemical corrosion resistance of the polyimide layer makes the valve less prone to damage when in contact with chemical media.

[0044] The multi-layered structure of the sealing ring 7 enhances its pressure resistance, high-temperature resistance, and chemical corrosion resistance, thus extending its service life. Traditional sealing rings 7 are prone to aging, deformation, or damage during prolonged operation due to pressure changes, high-temperature environments, and chemical corrosion, leading to a decline in sealing performance. However, this newly designed sealing ring 7, due to the advantages of each of its three components, can maintain good performance in various harsh environments, reducing valve failures caused by sealing ring 7 damage and further extending the valve's service life.

[0045] In some embodiments of this application, see Figure 4 As shown, the docking part 301 includes a first connecting pipe 3011, a second limiting ring 3012, and a fastening part 3013. The first connecting pipe 3011 is fixedly connected inside the second heat exchange tube. The fastening part 3013 is provided at the front end of the first connecting pipe 3011, and the second limiting ring 3012 is provided at the lower end of the fastening part 3013. The second limiting ring 3012 is used to prevent the fastening part 3013 from falling off.

[0046] Specifically, the docking part 301 is provided on the second water pipe 6, and a fastening part 3013 is provided on the outer surface of one end of the second water pipe 6. A second limiting ring 3012 is provided below the fastening part 3013. The second limiting ring 3012 is used to prevent the fastening part 3013 from falling off. The first connecting pipe 3011 is provided inside the second water pipe 6 and is fixedly connected to the second water pipe 6. When the second water pipe 6 is inserted into the first water pipe 5, the first connecting pipe 3011 fits against the first sealing gasket 410, and the fastening part 3013 is connected to the first limiting ring 3021.

[0047] Understandably, the combination of the fastening part 301, the fastening part 3013, and the second limiting ring 3012 makes the installation process of the multi-way ball valve simpler and faster. The installer only needs to align the front end of the second water pipe 6 with the first limiting hole 3022 on the first water pipe 5, and complete the installation with a simple insertion and rotation. The connection between the fastening part 3013 and the first limiting ring 3021 not only ensures the sealing and fixation of the first water pipe 5 and the second water pipe 6, but also simplifies the installation steps and reduces installation time. This plug-and-play design not only improves installation efficiency but also reduces human error during installation, ensuring a high success rate and reliability.

[0048] The design of the second limiting ring 3012 improves the connection reliability between the first water pipe 5 and the second water pipe 6 by preventing the fastening part 3013 from falling off. In traditional multi-way ball valves, the fastening part 3013 is prone to falling off due to improper operation during installation, leading to connection failure or poor sealing. The second limiting ring 3012, as a mechanical locking device, ensures that the fastening part 3013 will not fall off due to external force after being inserted into the first limiting hole 3022, improving the strength and reliability of the connection. This not only reduces the risks during installation but also allows the valve to maintain a stable connection state during long-term operation.

[0049] The first connecting pipe 3011 is fixedly connected to the second water pipe 6. When the second water pipe 6 is inserted into the first water pipe 5, the first connecting pipe 3011 tightly fits against the first sealing gasket 410, achieving multi-point sealing. In addition to the initial sealing provided by the first sealing gasket 410, another sealing point is formed between the first connecting pipe 3011 and the first water pipe 5. The tight fit of the first connecting pipe 3011 further enhances the sealing performance and reduces the risk of fluid leakage. Especially when the sealing ring 7 is fitted into the sealing groove, this multi-point sealing improves the overall sealing effect through the synergistic effect of multiple sealing points.

[0050] In critical applications such as the chemical and petroleum industries, safety is paramount for multi-way ball valves. Traditional multi-way ball valves are prone to fluid leakage due to poor sealing or loose connections, posing safety hazards. However, the multi-way ball valve in this embodiment ensures a tight connection between the first water pipe 5 and the second water pipe 6 through the dual protection of the fastening part 3013 and the second limiting ring 3012, reducing the risk of leakage. Furthermore, the tight fit between the first connecting pipe 3011 and the first sealing gasket 410 further enhances the sealing performance and improves the overall safety of the system.

[0051] The design of the docking part 301 simplifies the installation process and reduces reliance on high-precision measuring tools and specialized equipment. Traditional multi-way ball valve installation requires high-precision measuring tools and specialized equipment to ensure accurate alignment of all components. However, the multi-way ball valve, through the simple engagement of the fastening part 3013 and the second limit ring 3012, makes the installation process more intuitive and easier to operate. Installers do not need to use complex tools; installation can be completed simply by insertion and rotation. This not only reduces the cost of installation tools but also improves installation efficiency and success rate.

[0052] In some embodiments of this application, the fastening part 3013 includes a first fastener 3014, a second fastener 3015, and a fastening strip 3016. The first fastener 3014 has through holes 3017 arranged in a ring at equal intervals on its outer side. The through holes 3017 penetrate the first fastener 3014. The second fastener 3015 is inserted into the through holes 3017. The top of the second fastener 3015 penetrates the through holes 3017. The fastening strip 3016 is provided at the bottom of the second fastener 3015. The fastening strip 3016 is used to limit the position of the second fastener 3015.

[0053] Specifically, the fastening part 3013 includes a first fastener 3014, a second fastener 3015, and a fastening strip 3016. The first fastener 3014 has through holes 3017 arranged in a ring at equal intervals on its outer side. The second fastener 3015 is inserted into the through hole 3017, passing through the through hole 3017. The fastening strip 3016 is located at the bottom of the second fastener 3015. The second fastener 3015 and the fastening strip 3016 are fixedly connected. When the snap-fit ​​part 302 and the mating part 301... When the fastener is engaged, the first fastener 3014 fits against the first limiting ring 3021. The through hole 3017 on the first fastener 3014 corresponds to the first limiting hole 3022 on the first limiting ring 3021. The first fastener 3014 is inserted through the through hole 3017 and the first limiting hole 3022 to fasten the first fastener 3014 to the first limiting ring 3021. At the same time, the fastening strip 3016 is provided on the through hole 3017 on the side of the first fastener 3014 to limit the second fastener 3015.

[0054] Understandably, the fastening part 3013, through multi-point fastening of the first fastener 3014, the second fastener 3015, and the fastening strip 3016, enhances the vibration resistance of the connection. In some industrial environments, such as oil drilling platforms and chemical production plants, valves are frequently subjected to mechanical vibration and impact. Traditional fastening methods are prone to loosening due to vibration, leading to connection failure. However, through multi-point fixing and the limiting effect of the fastening strip 3016, the fastening part 3013 remains firmly in place under vibration and impact, reducing the risk of connection failure and poor sealing caused by vibration. The fastening part 3013, through its multi-point fixing and limiting structure, improves the durability of the connection. Traditional fastening methods are prone to failure due to wear and corrosion during long-term operation, while the fastening part 3013, through the tight fit of the first fastener 3014 and the second fastener 3015, and the limiting effect of the fastening strip 3016, makes the fastening part 3013 less prone to loosening during long-term operation, reducing connection failure caused by wear and corrosion. In addition, the fastening strip 3016 reduces the lateral movement of the second fastener 3015, making the connection of the fastening part 3013 more stable and reliable.

[0055] The through-hole 3017 and fastening strip 3016 in the design of the fastening part 3013 make the installation process more visible. Installers can intuitively judge whether the fastening part 3013 is installed correctly by observing the alignment of the through-hole 3017 with the first limiting hole 3022 and the limiting effect of the fastening strip 3016. This visualized installation process not only improves the success rate of installation but also reduces the risk of connection failure and poor sealing due to improper installation, making the installation process more transparent and controllable.

[0056] The multi-point fastening and limiting structure in the fastener 3013 design makes maintenance more convenient and efficient. Traditional fastening methods require special tools for disassembly and replacement, making the operation complex and prone to errors. Fastening, however, can be accomplished with simple insertion and rotation, and disassembly is also relatively simple. The fastening strip 3016 prevents the second fastener 3015 from falling off, reducing the risk of component loss during disassembly. Maintenance personnel can complete inspection and replacement in a shorter time, improving the system's maintainability.

[0057] The fastening element 3013, with its multi-point fixing and limiting structure, improves the system's fatigue resistance. During prolonged operation, fasteners are prone to fatigue failure, leading to loosening of the connection. However, through the synergistic effect of multiple fastening points and the limiting function of the fastening strip 3016, the fastening element 3013 maintains a stable connection during extended operation, reducing the risk of connection failure due to fatigue. This fatigue resistance makes the multi-way ball valve more reliable in high-load operating environments.

[0058] The fastening element 3013, with its multi-point fixing and limiting structure, improves the system's impact resistance. In high-impact environments, such as pipeline systems with strong water hammer effects, traditional fastening methods are prone to loosening due to impact, leading to connection failure. However, through the synergistic effect of multiple fastening points and the limiting function of the fastening strip 3016, the fastening element 3013 remains secure even under high impact conditions, reducing the risk of connection failure due to impact. This impact resistance makes the multi-way ball valve more reliable in complex operating conditions.

[0059] The fastening element 3013, with its multi-point fixing and limiting structure, improves the system's pressure resistance. Under high pressure, traditional fastening methods are prone to loosening due to excessive pressure, leading to connection failure. However, through the synergistic effect of multiple fastening points and the limiting function of the fastening strip 3016, the fastening element 3013 maintains a stable connection even under high pressure, reducing the risk of connection failure due to pressure changes. This pressure resistance makes the multi-way ball valve more reliable in high-pressure systems.

[0060] In some embodiments of this application, the rotating device includes a valve stem 9, a rotating wheel 10, and a connecting sleeve 11. The valve housing 1 is provided with the connecting sleeve 11, the valve stem 9 is located inside the valve housing 1, and its top passes through the connecting sleeve 11 to connect to the rotating wheel 10.

[0061] Understandably, the rotating device, through the connection between the valve stem 9 and the rotating wheel 10, provides a precise control mechanism. The valve stem 9 is located inside the valve body 1, and its top passes through the connecting sleeve 11 to connect to the rotating wheel 10. This allows the rotation of the rotating wheel 10 to be directly transmitted to the valve stem 9, thereby driving the ball 2 connected to the rocker arm, ensuring the accuracy of the ball 2's rotation and improving control precision. The rotating device provides multi-point support through the connecting sleeve 11 and the rotating wheel 10, enhancing the stability of the valve stem 9. The connecting sleeve 11 is fixed to the valve body 1, providing a stable connection point for the valve stem 9, while the rotating wheel 10, through its connection to the valve stem 9, provides additional support points. This disperses pressure, reduces the swaying and wear of the valve stem 9, and improves overall stability and reliability. The rotating device makes operation more convenient. The connection between the valve stem 9 and the rotating wheel 10 allows for simple rotational movement to limit or close the flow of the ball 2, reducing operational complexity and time.

[0062] In some embodiments of this application, the ball valve body further includes a sealing ring 7, which is disposed between the ball 2 and the first water pipe 5.

[0063] Understandably, the sealing ring 7, positioned between the ball 2 and the first water pipe 5, enhances the sealing performance of the multi-way ball valve through its tight fit with the valve body. Traditional ball valves often rely on a simple metal seal between the ball 2 and the water pipe. This seal is prone to failure due to wear and corrosion during prolonged operation, leading to fluid leakage. The introduction of the sealing ring 7 provides an additional sealing layer, making the seal between the ball 2 and the water pipe tighter and more reliable. The sealing ring 7 is typically made of highly elastic and corrosion-resistant materials, maintaining good sealing performance under various operating conditions and reducing the risk of fluid leakage.

[0064] The sealing ring 7 not only enhances sealing performance but also improves the durability of the valve body. In traditional ball valves, the metal-to-metal contact between the ball 2 and the water pipe is prone to failure due to wear and corrosion during prolonged operation, leading to internal damage to the valve body. However, the sealing ring 7 reduces direct friction between the metal parts, mitigating wear. Furthermore, the material chosen for the sealing ring 7 is typically more corrosion-resistant, maintaining good performance when in contact with chemical media, thus extending the valve body's service life.

[0065] The sealing ring 7, positioned between the ball 2 and the first water pipe 5, optimizes fluid flow through the valve body. Traditional ball valves often suffer from insufficiently precise sealing designs between the ball 2 and the water pipe, leading to eddies and pressure losses during fluid flow. The sealing ring 7, however, ensures a tighter and more uniform seal between the ball 2 and the water pipe, reducing resistance and eddies and improving fluid flow efficiency. This is particularly important in high-flow and high-pressure applications, enhancing the overall system performance.

[0066] In some embodiments of this application, a filter device 8 is also included, which is disposed on one side of the sealing unit 4 and is used to filter impurities in the fluid.

[0067] Understandably, the filter device 8 is located on one side of the sealing unit 4 and is capable of filtering impurities from the fluid. In many industrial applications, the fluid may contain various particles, iron filings, silt, and other impurities. These impurities can not only affect the normal operation of the valve but may also damage the sealing unit 4. The filter device 8, through its filtration function, can trap these impurities inside the filter device 8, ensuring that the fluid passing through the valve is purer. This not only extends the service life of the valve but also guarantees the stable operation of the system.

[0068] The filter device 8 protects the internal components of the valve by filtering impurities from the fluid. For example, internal components such as the ball 2, valve seat, and sealing ring 7 are prone to wear, corrosion, or jamming after contact with impurities, leading to valve malfunction. The filter device 8 reduces the contact between these impurities and the internal components, allowing them to maintain good performance over a longer period. This not only extends the valve's service life but also reduces maintenance and replacement costs due to damage to internal components.

[0069] In some embodiments of this application, the limiting unit 3 is a rigid component made of stainless steel or alloy steel.

[0070] Understandably, the limit unit 3 is made of rigid components of stainless steel or alloy steel, which improves its corrosion resistance. In some highly corrosive industrial environments, such as the chemical, petroleum, and pharmaceutical industries, the fluids may contain various corrosive substances that can easily corrode metal components and affect the normal function of the valve. Stainless steel and alloy steel have excellent corrosion resistance and can resist the erosion of most chemical media, ensuring that the limit unit 3 maintains good performance and structural integrity during long-term operation. This not only extends the service life of the limit unit 3 but also reduces maintenance and replacement costs caused by corrosion.

[0071] The limiting unit 3 is made of stainless steel or alloy steel, enhancing its mechanical strength. In high-pressure and high-flow pipeline systems, the limiting unit 3 needs to withstand significant mechanical stress. Traditional materials such as ordinary carbon steel are prone to deformation or damage under these conditions, affecting the stability and reliability of the valve. Stainless steel and alloy steel, however, possess higher mechanical strength and hardness, enabling them to withstand higher pressures and flow rates, ensuring that the limiting unit 3 maintains stable structure and performance even under complex operating conditions. This not only improves the reliability and safety of the multi-way ball valve but also allows it to be applied to a wider range of high-load working environments.

[0072] Limiting unit 3 is made of stainless steel or alloy steel, which improves its high-temperature resistance. In some high-temperature conditions, limiting unit 3 needs to operate for extended periods in high-temperature environments. Stainless steel and alloy steel have excellent high-temperature stability, maintaining good physical and chemical properties in high-temperature environments and preventing material softening or deformation caused by high temperatures. This high-temperature resistance design allows the multi-way ball valve to better adapt to high-temperature environments, ensuring stable system operation.

[0073] In some embodiments of this application, the limiting unit 3 is coated with a high-temperature resistant and corrosion-resistant coating.

[0074] Understandably, high-temperature resistant and corrosion-resistant coatings maintain their stability and protective performance under high-temperature conditions. In industries such as petrochemicals, metallurgy, and aerospace, operating temperatures can reach hundreds of degrees Celsius or even higher. This type of coating prevents oxidation and performance degradation of metal surfaces in high-temperature environments, ensuring the normal operation of valves under these conditions. Compared to uncoated metal surfaces, high-temperature resistant coatings improve the thermal stability of materials, reduce the impact of thermal stress on the internal structure of valves, and extend the service life of valves.

[0075] High-temperature resistant and corrosion-resistant coatings possess excellent corrosion resistance, maintaining good chemical stability and mechanical properties in corrosive media such as acids, alkalis, and salts. In highly corrosive conditions, such as in chemical plants and wastewater treatment plants, corrosive substances in the fluid can severely damage metal components, leading to valve failure. This coating provides an additional protective layer in these corrosive environments, preventing corrosion of metal surfaces, improving the valve's corrosion resistance, and extending its service life. Furthermore, the coating reduces material fatigue and structural damage caused by corrosion, ensuring the stability and reliability of the valve during long-term operation. The high-temperature resistant and corrosion-resistant coating has a low surface roughness, reducing friction between the fluid and the valve's internal surfaces. As fluid passes through the valve, the low surface roughness reduces turbulence and irregular flow, minimizing impact and wear on internal valve components. This not only improves fluid transmission efficiency but also extends the valve's service life and reduces maintenance costs.

[0076] The multi-way ball valve in the above embodiments is configured by splitting the ball valve pipeline. The first water pipe is fixedly connected to the upper tube sheet, and the second water pipe is snap-fitted to the first water pipe. The first and second water pipes are sealed and fixed by the snap-fit ​​part and the butt joint part, which improves the convenience of installing and disassembling the water pipes. Compared with the traditional connection method, it simplifies the installation process and reduces installation time and cost. When the water pipe needs to be replaced or maintained, only the snap-fit ​​connection part needs to be removed, without the need for a cumbersome disassembly process, which improves the convenience and efficiency of maintenance and reduces maintenance costs. At the same time, the first and second water pipes are under high temperature and high pressure conditions for a long time, and the snap-fit ​​connection method can distribute stress and reduce stress concentration points, thereby improving the mechanical strength and service life of the equipment.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
