[0046] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Specific embodiment one:

[0048] Such as Figure 1-17As shown in the figure, the integrated multi-mode hierarchical adjustable liquid distribution valve includes a main valve body 1, a multi-way connection seat 18 and a feed pipe 6. On the outer side surface of the main valve body 1, there are respectively an IN feed port 2, an OUT discharge port 3, a TC material port 4 and an FC material port 5. The top surface of the main valve body 1 is connected with a feed pipe 6. The bottom of the main valve body 1 is provided with an oil filter seat 8. On the side surface of the main valve body 1, there are respectively connected with a solenoid valve 9 and a pressure valve 7. At the top of the IN feed port 2, there is a gas supply port 11. At the top of the FC material port 5, there is a vent port 10. The inner walls of the IN feed port 2, the OUT discharge port 3, the TC material port 4 and the FC material port 5 are all provided with recovery grooves, and the internal structures of the recovery grooves are the same. The sizes of the splicing ports 24 on the surface of the multi-way connection seat 18 correspond one by one to the IN feed port 2, the OUT discharge port 3, the TC material port 4 and the FC material port 5. The outer wall of the flexible spring tube 20 abuts against the inner wall of the splicing port 24. The main valve body 1 is the core component of the entire integrated multi-mode hierarchical adjustable liquid distribution valve, providing a main place for the flow, processing and control of materials. Materials enter the fluid distribution valve body from the IN feed port 2. Through the action of the internal channels and structures in the valve body, the processed materials can be output from the OUT discharge port 3 as needed, realizing a small cycle of one material. Materials enter from the IN feed port 2, pass through the TC material port 4 and the FC material port 5, and finally discharge from the OUT discharge port 3, forming a large cycle. Select the opening and closing of the corresponding channel material ports according to the actual operation requirements. The TC material port 4 and the FC material port 5 are used for connection with external devices. For example, the TC material port 4 is used for distribution to a cooler, and the FC material port 5 is used for the materials in the cooler to enter the inside of the main valve body 1. By externally connecting a cooler, the materials inside the main valve body 1 can be cooled. Select the externally connected devices for use according to the actual usage requirements.

[0049] One end surface of the multi-way connector 18 is provided with a plurality of splicing ports 24. One end of the multi-way connector 18 close to the distribution port 19 is conical. The other end of the multi-way connector 18 is provided with a distribution port 19. A flexible spring tube 20 is connected inside the splicing port 24. The flexible spring tube 20 is engaged with the material port on the surface of the main valve body 1. A first connecting pipe 28 is sleeved inside the distribution port 19. A multi-way ball seat 25 is connected to the end of the first connecting pipe 28. A second sleeve pipe 30 is provided on one side of the multi-way ball seat 25 away from the first connecting pipe 28. A splicing sleeve 29 is connected to the surface of the first connecting pipe 28 through a bearing. The inner wall of the splicing sleeve 29 is threadedly connected to the end of the distribution port 19. On the one hand, the splicing port 24 of the multi-way connector 18 is used to connect the respective material ports of the fluid distribution valve body, and the flexibility and operability of the connection are realized through the flexible spring tube 20. On the other hand, its distribution port 19 is used to connect subsequent distribution components, such as the multi-way ball seat 25, etc., so as to realize the transmission and guidance of materials between different ports and components. Multiple multi-way connectors 18 can also be spliced with each other to expand the distribution direction and path. The splicing port 24 is connected to the material port of the fluid distribution valve body by means of the flexible spring tube 20. The flexible spring tube 20 can adapt to certain installation errors and vibrations, etc., to ensure the stability of the connection. Through the connection with the first connecting pipe 28, the multi-way ball seat 25, etc., the distribution port 19 guides the materials entering from the fluid distribution valve body to different paths. For example, when the materials enter the multi-way connector 18 from a certain material port of the fluid distribution valve body, they will flow to the components connected to the corresponding distribution port 19 according to the structure and connection conditions of the multi-way connector 18. The adjacent multi-way connectors 18 are assembled through the cooperation of the first connecting pipe 28 and the second sleeve pipe 30 with the splicing sleeve 29. The inner wall of the splicing sleeve 29 is threadedly connected to the end of the distribution port 19, making the connection firm and convenient for installation and disassembly. Through the modular design, the flexible connection between the fluid distribution valve body and other distribution components is realized, improving the scalability and adaptability of the entire system. Different numbers and connection methods of multi-way connectors 18 can be selected according to actual needs to realize the diversion and guidance control in multiple directions at different horizontal positions, enabling the fluid distribution valve body to achieve the distribution of one into multiple, increasing the adaptability of the distribution. At the same time, its cooperation with the multi-way ball seat 25, etc., helps to achieve the distribution effects of multiple into multiple and multiple into one. Adopting modular assembly, it can be quickly assembled and adapted to the use requirements.

[0050] The feed pipe 6 is the inlet channel for the material to enter the main body of the fluid distribution valve, introducing the external material into the fluid distribution valve for subsequent processing. The inner wall circumference of the IN feed port 2 is provided with a recovery cavity 17. Inside the recovery cavity 17, there is a limit shaft arm 15. Near the bottom end of the limit shaft arm 15, there is a torsion spring shaft 16, and both ends of the torsion spring shaft 16 are movably engaged with the inner wall of the recovery cavity 17. At the top of the limit shaft arm 15, there is a T-shaped locking block 14. On the outer surface circumference of the feed pipe 6, there is a T-shaped arc groove 12. At the end of the T-shaped arc groove 12, there is a T-shaped card slot 13, and the T-shaped card slot 13 penetrates through the T-shaped arc groove 12. Under the action of the torsion spring shaft 16, in the normal state, the limit shaft arm 15 is in an open state towards both sides, with its short end slightly tilted upwards, and the top end is located inside the recovery groove. When making a connection, taking the feed pipe 6 as an example, the end of the feed pipe 6 is inserted along the IN feed port 2. The bottom end contacts the bottom end of the limit shaft arm 15, and as it is inserted, the end of the limit shaft arm 15 is pressed downwards, causing the top end of the limit shaft arm 15 to approach the feed pipe 6 along the torsion spring shaft 16. Until the feed pipe 6 is completely inserted, at this time, the bottom surface of the bottom end of the limit shaft arm 15 is horizontal, the T-shaped locking block 14 at the end of the limit shaft arm 15 is vertical and abuts against the T-shaped card slot 13 on the surface of the feed pipe 6. At this time, the T-shaped locking block 14 has entered the end of the T-shaped arc groove 12. Rotate the feed pipe 6 to make the entire T-shaped locking block 14 completely enter the inner wall of the T-shaped arc groove 12, and the rapid installation of the feed pipe 6 and the IN feed port 2 is completed. When disassembling, reverse-rotate the feed pipe 6 until the T-shaped locking block 14 and the T-shaped card slot 13 are in the opposite position, and then pull it out upwards. At this time, the limit shaft arm 15 is affected by the rebound of the bottom torsion spring shaft 16 and maintains its initial open state. This quick-disassembly structure enables the feed pipe 6 to be conveniently and quickly connected to the main body of the fluid distribution valve, improving the assembly efficiency, facilitating the operation of the feed pipe 6 during equipment installation, maintenance, and adjustment, and reducing the installation time and labor costs.

[0051] There are multiple multi-way ball seats 25. The surface connection structures of adjacent multi-way ball seats 25 are the same. Adjacent multi-way ball seats 25 are assembled through the cooperation of the first connecting pipe 28 and the second sleeve 30 with the splicing sleeve 29. The surface of the multi-way ball seat 25 is provided with a flow splitting port 26. The end of the flow splitting port 26 is embedded with a sealing valve 27. The sizes, positions, and quantities of the flow splitting ports 26 on the surfaces of adjacent multi-way connection seats 18 are different. Threads are provided on the outer wall of the second sleeve 30 and the inner wall of the splicing sleeve 29. The multi-way ball seat 25 is used in cooperation with the multi-way connection seat 18 and can also be used alone. It is mainly used to achieve multi-directional flow splitting and guiding of materials. The multiple flow splitting ports 26 on its surface can distribute the materials entering from the distribution port 19 of the multi-way connection seat 18 to different paths or ports. The distribution port 19 of the multi-way connection seat 18 is connected to the multi-way ball seat 25 through the first connecting pipe 28. After the materials enter the multi-way ball seat 25, according to its internal channel structure and the setting of the flow splitting ports 26, they flow in different directions. For example, when it is necessary to split the materials from one inlet to multiple outlets, the multi-way ball seat 25 can evenly or according to a specific ratio distribute the materials to each outlet path according to the layout and connection of its flow splitting ports 26. By splicing the multi-way ball seat 25 with the material ports on the surface of the fluid distribution valve body, and using the multiple flow splitting ports 26 on the surface of the multi-way ball seat 25, the splitting of the materials at multiple ports on the surface of the fluid distribution valve body can be realized, enabling the entire main valve body 1 to achieve the distribution effects of multi-way multi-outlets and multi-way one-outlet under the cooperation of the multi-way connection seat 18 and the multi-way ball seat 25. With modular assembly, it can be quickly assembled and adapted to the usage requirements, greatly improving the adaptability and flexibility of the fluid distribution valve system to different distribution requirements.

[0052] The first connecting pipe 28 is mainly used to connect the distribution port 19 of the multi-way connection seat 18 and the multi-way ball seat 25, realizing the construction of the material transmission channel between the two. After inserting the first connecting pipe 28 into the second sleeve 30, the splicing sleeve 29 on the surface of the first connecting pipe 28 is rotated to be thread-assembled with the surface of the second sleeve 30. These components jointly construct the connection system between the multi-way connection seat 18 and the multi-way ball seat 25 and between adjacent multi-way connection seats 18, enabling the modular assembly of the entire fluid distribution valve system to be realized. Their structural design ensures the firmness of the connection, the stability of material transmission, and the convenience of the assembly process, and can flexibly combine different multi-way connection seats 18 and multi-way ball seats 25 according to actual needs to realize the construction of complex distribution paths, improving the scalability and adaptability of the system. Specific Embodiment 2:

[0054] As Figure 1-17 shown, based on the content in the above specific embodiment, the following content is further disclosed:

[0055] The entire flexible bellows 20 is used for connection with multiple material inlets. A magnetic attraction cover plate 22 is sleeved at the end of the flexible bellows 20. A magnetic attraction groove 21 is formed at the outer edge position of the splicing port 24 on the surface of the multi-way connection seat 18, and the magnetic attraction groove 21 is a blind groove. A flexible belt 23 is provided between the magnetic attraction cover plate 22 and the end of the flexible bellows 20. The magnetic attraction groove 21 and the magnetic attraction cover plate 22 are in clearance fit. As a connecting component between the multi-way connection seat 18 and the material inlet of the fluid distribution valve body, the flexible bellows 20 can not only ensure the transmission of materials, but also adapt to certain installation deviations and relative movements. At the same time, it is also involved in the quick disassembly and installation process of the connection. The flexible bellows 20 has a certain elasticity and flexibility and can be bent and stretched within a certain range to adapt to different installation positions and angle requirements. During the connection process, a T-shaped arc groove 12 and a T-shaped clamping groove 13 are formed on the circumferential surface of the end of the flexible bellows 20 away from the multi-way connection seat 18. The flexible characteristics of the flexible bellows 20 improve the reliability and adaptability of the connection of the entire fluid distribution valve system and can ensure the stability of material transmission in a complex installation environment and working conditions. Its quick-disassembly structure design facilitates the connection and disassembly operations between the fluid distribution valve body and the multi-way connection seat 18, improves the maintainability and operability of the system, further simplifies the installation steps, and improves the installation efficiency.

[0056] To reduce the volume of the entire multi-way connection seat 18, when not in use, the flexible bellows 20 is squeezed and contracted into the inside of the splicing port 24. During contraction, the end of the flexible bellows 20 close to the magnetic attraction cover plate 22 is compressed synchronously, so that the surface of the magnetic attraction cover plate 22 abuts against the magnetic attraction groove 21, realizing the covering of the end of the flexible bellows 20 and preventing the contracted flexible bellows 20 from popping out, and maintaining the contracted state. When connection is required, the magnetic attraction cover plate 22 is pulled outwards by the flexible belt 23 to be separated from the magnetic attraction groove 21. At this time, the end of the flexible bellows 20 no longer blocks, and it can be pulled out and connected to the material inlet on the surface of the main valve body 1 to access materials. Through the retractable and foldable structure, the volume of the multi-way connection seat 18 is effectively reduced, which is convenient for storage. At the same time, it prevents the flexible bellows 20 from being bent, extends the service life, and is convenient for storage. Specific Embodiment Three:

Different levels of material distribution are carried out through the diversion port 26 of the multi-pass ball seat 25 connected to the surface. By controlling the opening and closing of the sealing valve 27, the direction and rate of the diversion are controlled; one or more multi-pass ball seats 25 can be selected for assembly and use according to needs.

As Figure 5 shown, there is one diversion port 26 on the surface of the multi-way ball seat 25 close to the T-shaped arc groove 12. On the basis of one diversion port 26, the diversion ports 26 on the surface of the next multi-way ball seat 25 add a small diversion port 26. There are four diversion ports 26 on the surface of the next-next multi-way ball seat 25, and so on. When setting the diversion ports 26, they can be set according to rules, such as powers of 2, or they can be set according to an arithmetic sequence or a geometric sequence. At the same time, they can also be directly set and used without order, so that the sizes of the opened diversion ports 26 are widely adapted to the existing pipeline sizes, realizing the adaptability of the discharge to the pipeline. Specific Embodiment Six:

[0071] As Figure 1-17 shown, based on the content in the above specific embodiments, the following content is further disclosed:

[0072] When the entire interior of the multi-way ball seat 25 is used for guiding the diversion ports 26, the following two structures can be adopted:

[0073] As Figure 17 shown, a main pipeline can be provided inside the multi-way ball seat 25 to connect the first connecting pipe 28 and the second sleeve 30 for use, and a plurality of branch pipelines are provided on the side of the main pipeline. The branch pipelines are connected to the ends of the diversion ports 26. After the material enters the main pipeline, it enters the diversion pipeline, realizing the diversion use of the material. At this time, the sealing valve 27 can be provided at the end of the diversion port 26 or at the connection position between the branch pipeline and the main pipeline to realize the diversion use of the material.

[0074] As Figure 16 shown, the interior of the multi-way ball seat 25 can be an entire cavity, and several diversion ports 26 are provided on the outer surface. Sealing valves 27 are provided inside the diversion ports 26. When distributing the material, to facilitate the material to flow out from each diversion port 26, it is necessary to first fill the entire interior of the multi-way ball seat 25 with the material, and then open the sealing valve 27 for discharging, realizing multi-channel discharging.

[0075] Select the corresponding internal structure setting of the multi-way ball seat 25 according to the actual use requirements. Specific Embodiment Seven:

[0077] AsFigure 1-17 As shown in the above specific embodiments, the following content is further disclosed:

[0078] During actual use of the entire main valve body 1, the connections and assemblies between various pipelines and material inlets / outlets are all maintained in a sealed structure. The flow directions of the various channels inside the main valve body 1 can be set in combination with the corresponding publicly available technical documents in the art. This application mainly focuses on setting the modular hierarchical quick disassembly and connection of the main valve body 1. The flow directions of the internal channels can be selected and set according to the actual use scenarios and technologies.

[0079] The sealing valve 27 in this application can be one of the existing valve body butterfly valves, ball valves or other valve body structures.

[0080] Through the above structural content, a highly flexible and efficient material distribution function is achieved. The modular assembly characteristics of the multi-way connection seat 18 not only allow the construction of multiple diversion and guiding paths in different horizontal positions to achieve an efficient distribution mode of one input and multiple outputs, greatly broadening the adaptation range of the fluid distribution valve in complex process flows, but also, according to the actual discharge requirements, with the help of the convenient connection method between the flexible spring tube 20 and the material inlet / outlet of the fluid distribution valve body 1, accurately select and connect one or more corresponding material inlets / outlets. Combining with the multi-diversion port design of the multi-way ball seat, a diversified distribution effect of multiple inputs and multiple outputs and multiple inputs and one output is realized, fully meeting the stringent requirements for flow distribution under various working conditions. The widely used quick disassembly structure between components greatly simplifies the assembly process, significantly shortening the time and labor input required for equipment installation, maintenance and adjustment. This not only effectively improves production efficiency, reduces operation and maintenance costs, but also enhances the reliability and stability of the entire fluid distribution valve in actual industrial application scenarios, providing a highly competitive and innovative solution for the material handling and transmission operations in related industries.
