[0022] Beneficial effects

[0023] This invention provides an integrated multi-mode graded adjustable liquid distribution valve. It has the following beneficial effects:

[0024] 1. This invention uses a multi-port ball seat for connection and distribution outside the main valve body. By splicing the multi-port ball seat with the material port on the surface of the main valve body, and utilizing the multiple diversion ports on the surface of the multi-port ball seat, the material on the surface of the main valve body can be diverted to multiple ports. At the same time, by splicing between multiple adjacent multi-port connecting seats, the diversion and guidance control in multiple directions at different horizontal positions can be achieved. The modular assembly and distribution allows the main valve body to achieve one-port-multiple-outlet distribution, increasing the adaptability of the distribution.

[0025] 2. This invention utilizes a multi-port connector and a multi-port ball seat on the surface of the main valve body to achieve material discharge from the surface ports. Depending on the number of discharge ports, one or more corresponding flexible spring tubes can be selected for connection. Simultaneously, a multi-port ball seat is connected at the distribution port of the multi-port connector for material discharge. This allows the entire main valve body to achieve multi-port / multi-outlet and multi-port / single-outlet distribution effects through the cooperation of the multi-port connector and the multi-port ball seat. Modular assembly allows for rapid assembly and adaptation to usage requirements, achieving diverse distribution effects of multi-port / multi-outlet and multi-port / single-outlet. The flexible modular assembly and connection between components facilitates various forms of material distribution control, such as multi-port / multi-outlet or multi-port / single-outlet, according to different working conditions. This effectively solves the problem of poor distribution flexibility and fully meets the stringent requirements for flow distribution under various working conditions.

[0026] 3. This invention employs a T-shaped arc groove at the end of the feed pipe, multi-way connector, and multi-way ball seat connected to the main valve body surface. This T-shaped arc groove engages with the limiting shaft arm inside the feed port. When the feed pipe is inserted into the main valve body, a slight rotation after insertion allows the limiting shaft arm to engage with the T-shaped arc groove, enabling rapid installation and positioning of the feed pipe. The quick-release structure facilitates rapid assembly of the pipes on the main valve body surface, as well as rapid assembly between multi-way ball seats and between multi-way ball seats and multi-way connectors. This convenient installation greatly simplifies the assembly process and significantly reduces the time and manpower required for equipment installation, maintenance, and adjustment. This not only effectively improves production efficiency and reduces operating costs but also enhances the reliability and stability of the entire main valve body in actual industrial applications.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Specific Implementation Example 1:

[0048] like Figure 1-17As shown, the integrated multi-mode graded adjustable liquid distribution valve includes a main valve body 1, a multi-port connector 18, and an inlet pipe 6. The outer side of the main valve body 1 is provided with an IN inlet 2, an OUT outlet 3, a TC inlet 4, and an FC inlet 5. The inlet pipe 6 is connected to the top surface of the main valve body 1, and an oil filter seat 8 is located at the bottom. A solenoid valve 9 and a pressure valve 7 are connected to the sides of the main valve body 1. An air supply port 11 is located at the top of the IN inlet 2, and a vent port 10 is located at the top of the FC inlet 5. The inner walls of the IN inlet 2, OUT outlet 3, TC inlet 4, and FC inlet 5 are all provided with recovery grooves, and the internal structures of these recovery grooves are all identical. The size of the splicing port 24 on the surface of the multi-port connector 18 corresponds one-to-one with the IN inlet 2, OUT outlet 3, TC inlet 4, and FC inlet 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 entire integrated multi-mode... The core component of the modular adjustable liquid distribution valve provides the main location for material flow, processing, and control. Material enters the main body of the fluid distribution valve from the IN inlet 2, and after passing through the internal channels and structures within the valve body, the processed material can be output from the OUT outlet 3 as needed, realizing a small-scale material circulation. Material enters from the IN inlet 2, passes through the TC outlet 4 and the FC outlet 5, and finally exits from the OUT outlet 3, forming a large circulation. The opening and closing of the corresponding channel outlets can be selected according to the actual operating requirements. The TC outlet 4 and the FC outlet 5 are used for connection with external equipment. For example, the TC outlet 4 is used for distribution to the cooler, and the FC outlet 5 is used for material in the cooler to enter the main valve body 1. Through the external connection to the cooler, the material inside the main valve body 1 is cooled. The external connection equipment is selected for use according to the actual usage requirements.

[0049] The multi-port connector 18 has multiple splicing ports 24 on one end surface. The end of the multi-port connector 18 near the distribution port 19 is tapered, and the other end of the multi-port connector 18 has a distribution port 19. A flexible spring tube 20 is connected inside the splicing port 24, and the flexible spring tube 20 engages with the feed port on the surface of the main valve body 1. A first connecting tube 28 is sleeved inside the distribution port 19, and a multi-port ball seat 25 is connected to the end of the first connecting tube 28. A second sleeve 30 is provided on the side of the multi-port ball seat 25 away from the first connecting tube 28. A splicing sleeve 29 is connected to the surface of the first connecting tube 28 through a bearing. The inner wall of the splicing sleeve 29 is connected to the distribution port 19. The multi-port connector 18 features an end threaded connection. On one hand, its splicing port 24 connects to various inlets of the fluid distribution valve body, achieving flexibility and operability through a flexible spring tube 20. On the other hand, its distribution port 19 connects to subsequent distribution components, such as a multi-port ball seat 25, enabling material transfer and guidance between different ports and components. Multiple multi-port connectors 18 can also be spliced ​​together to expand the distribution direction and path. The splicing port 24 connects to the fluid distribution valve body inlet via the flexible spring tube 20, which can adapt to certain installation errors and vibrations, ensuring connection stability. The distribution port 19, through its connection to the first connecting pipe 28, multi-port ball seat 25, etc., guides material entering from the fluid distribution valve body to different paths. For example, when material enters the multi-port connector 18 from a certain inlet of the fluid distribution valve body, it flows to the corresponding component connected to the distribution port 19, depending on the structure and connection of the multi-port connector 18. Adjacent multi-port connectors 18 are assembled using a first connecting pipe 28 and a second set of connecting pipes 30 in conjunction with a splicing sleeve 29. The inner wall of the splicing sleeve 29 is threaded to the end of the distribution port 19, ensuring a secure connection and facilitating installation and disassembly. This modular design enables flexible connection between the fluid distribution valve body and other distribution components, improving the scalability and adaptability of the entire system. Different numbers and connection methods of multi-port connectors 18 can be selected according to actual needs, achieving multi-directional flow guidance control at different horizontal positions. This allows the fluid distribution valve body to achieve one-port-multiple-outlet distribution, increasing its adaptability. Furthermore, its cooperation with multi-port ball seats 25, etc., helps achieve multi-port-multiple-outlet and multi-port-single-outlet distribution effects. The modular assembly allows for rapid assembly and adaptation to usage requirements.

[0050] Feed pipe 6 is the inlet channel for materials to enter the fluid distribution valve body, introducing external materials into the fluid distribution valve for subsequent processing. A recovery chamber 17 is circumferentially formed on the inner wall of the IN feed port 2. A limiting arm 15 is located inside the recovery chamber 17. A torsion spring shaft 16 is located near the bottom of the limiting arm 15, and both ends of the torsion spring shaft 16 are movably engaged with the inner wall of the recovery chamber 17. A T-shaped locking block 14 is located at the top of the limiting arm 15. A T-shaped arc groove 1 is circumferentially formed on the surface of the feed pipe 6. 2. The end of the T-shaped arc groove 12 is provided with a T-shaped slot 13, and the T-shaped slot 13 passes through the T-shaped arc groove 12. Under the action of the torsion spring shaft 16, the limiting shaft arm 15 is in a state of being open to both sides in the normal state, with its air gap slightly tilted upwards and its top end located inside the recycling tank. When connecting, taking the feed pipe 6 as an example, the end of the feed pipe 6 is inserted along the IN feed port 2, and the bottom end contacts the bottom end of the limiting shaft arm 15. As it is inserted, the end of the limiting shaft arm 15 is pressed down, so that the limiting shaft arm 15 is closed. The top of the limiting arm 15 moves towards the feed pipe 6 along the torsion spring shaft 16 until the feed pipe 6 is fully inserted. At this time, the bottom surface of the limiting arm 15 remains horizontal, and the T-shaped locking block 14 at the end of the limiting arm 15 remains vertical and abuts against the T-shaped locking groove 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 so that the entire T-shaped locking block 14 is fully inserted into the inner wall of the T-shaped arc groove 12, thus completing the quick installation of the feed pipe 6 and the IN feed port 2. When disassembling, rotate the feed pipe 6 in the opposite direction until the T-shaped locking block 14 and the T-shaped locking groove 13 are in the opposite position, and pull it upward. At this time, the limiting arm 15 is held in the initial open state by the spring action of the bottom torsion spring shaft 16. This quick-release structure allows the feed pipe 6 to be easily and quickly connected to the fluid distribution valve body, improving assembly efficiency and facilitating operation of the feed pipe 6 during equipment installation, maintenance and adjustment, reducing installation time and labor costs.

[0051] Multiple multi-pass ball seats 25 are provided. The surface connection structure of adjacent multi-pass ball seats 25 is the same. Adjacent multi-pass ball seats 25 are assembled with a first connecting pipe 28 and a second set of connecting pipes 30 and a splicing sleeve 29. The surface of the multi-pass ball seat 25 is provided with a diversion port 26. A sealing valve 27 is embedded at the end of the diversion port 26. The size, position and number of diversion ports 26 on the surface of adjacent multi-pass connecting seats 18 are different. The outer wall of the second set of connecting pipes 30 and the inner wall of the splicing sleeve 29 are both provided with threads. The multi-pass ball seat 25 is used in conjunction with the multi-pass connecting seat 18, or it can be used alone. It is mainly used to realize multi-directional diversion and guidance of materials. The multiple diversion ports 26 on its surface can distribute material entering from the distribution port 19 of the multi-way connector 18 to different paths or ports. The distribution port 19 of the multi-way connector 18 is connected to the multi-way ball seat 25 through the first connecting pipe 28. After the material enters the multi-way ball seat 25, it flows in different directions according to its internal channel structure and the setting of the diversion ports 26. For example, when it is necessary to divert material from one inlet to multiple outlets, the multi-way ball seat 25 can distribute the material evenly or according to specific directions based on the layout and connection of its diversion ports 26. The fluid is proportionally distributed to each outlet path. By splicing the multi-port ball seat 25 with the material port on the surface of the fluid distribution valve body, and utilizing the multiple diversion ports 26 on the surface of the multi-port ball seat 25, the material on the surface of the fluid distribution valve body can be diverted to multiple ports. This allows the entire main valve body 1 to achieve multi-port and multi-outlet distribution effects with the cooperation of the multi-port connecting seat 18 and the multi-port ball seat 25. The modular assembly allows for quick assembly and adaptation to usage requirements, greatly improving the adaptability and flexibility of the fluid distribution valve system to different distribution needs.

[0052] The first connecting pipe 28 is mainly used to connect the distribution port 19 of the multi-way connecting seat 18 and the multi-way ball seat 25, realizing the material transfer channel between them. After the first connecting pipe 28 is inserted into the second set of connecting pipes 30, it is rotated through the splicing sleeve 29 on the surface of the first connecting pipe 28 to be threaded onto the surface of the second set of connecting pipes 30. These components together construct the connection system between the multi-way connecting seat 18 and the multi-way ball seat 25, as well as between adjacent multi-way connecting seats 18, enabling the modular assembly of the entire fluid distribution valve system. Their structural design ensures the robustness of the connection, the stability of material transfer, and the convenience of the assembly process. Different multi-way connecting seats 18 and multi-way ball seats 25 can be flexibly combined according to actual needs to realize the construction of complex distribution paths, improving the scalability and adaptability of the system. Specific Implementation Example 2:

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

[0055] The entire flexible spring tube 20 is used for connection with multiple feed ports. A magnetic cover plate 22 is sleeved at the end of the flexible spring tube 20. A magnetic groove 21 is formed on the outer edge of the splicing port 24 on the surface of the multi-port connector 18. The magnetic groove 21 is a blind groove. A flexible strip 23 is provided between the magnetic cover plate 22 and the end of the flexible spring tube 20. The magnetic groove 21 and the magnetic cover plate 22 are clearance-fitted. The flexible spring tube 20, as the connecting component between the multi-port connector 18 and the feed port of the fluid distribution valve body, can ensure material transmission, adapt to certain installation deviations and relative movements, and also participate in the quick disassembly and installation process. The flexible spring tube 20 has certain... The flexible and resilient spring tube 20 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 retaining groove 13 are formed on the circumference of the end of the flexible spring tube 20 away from the multi-way connector 18. The flexibility of the flexible spring tube 20 improves the reliability and adaptability of the entire fluid distribution valve system connection, ensuring the stability of material transmission under complex installation environments and working conditions. Its quick-release structure design facilitates the connection and disassembly operations between the fluid distribution valve body and the multi-way connector 18, improving the maintainability and operability of the system, further simplifying the installation steps, and improving installation efficiency.

[0056] To reduce the overall volume of the multi-port connector 18, when not in use, the flexible spring tube 20 is compressed and retracted to the inside of the splicing port 24. During retraction, the end of the flexible spring tube 20 near the magnetic cover plate 22 is simultaneously compressed, causing the surface of the magnetic cover plate 22 to abut against the magnetic groove 21. This covers the end of the flexible spring tube 20 while preventing it from popping out after retraction, keeping it in a retracted state. When connection is needed, the magnetic cover plate 22 is stretched outward using the flexible band 23 until it detaches from the magnetic groove 21. At this time, the end of the flexible spring tube 20 is no longer obstructed and can be pulled out to connect with the material inlet on the surface of the main valve body 1 for material intake. Through the retractable and foldable structure, the volume of the multi-port connector 18 is effectively reduced, making it easy to store. At the same time, it prevents the flexible spring tube 20 from bending, extends its service life, and facilitates storage. Specific Implementation Example 3:

[0058] like Figure 1-17 As shown, based on the content of the above specific embodiments, the following content is further disclosed:

[0059] In actual use, in addition to the threaded connection through the splicing sleeve 29, the connection structure between the multi-pass ball seats 25 can also be used by opening a T-shaped arc groove 12 and a T-shaped slot 13 with the same structure as the surface of the feed pipe 6 on the surface of the first connecting pipe 28. At this time, the second set of connecting pipes 30 is equipped with a recycling groove, a limiting shaft arm 15, a torsion spring shaft 16 and a T-shaped block 14 with the same structure as the IN feed port 2. Adjacent multi-pass ball shafts can be quickly assembled and used by engaging the T-shaped arc groove 12 and the limiting shaft arm 15.

[0060] In addition to the threaded installation using the splicing sleeve 29, the connection structure between the distribution port 19 of the multi-port connector 18 and the first connecting pipe 28 of the multi-port ball seat 25 uses the splicing sleeve 29. The surface of the first connecting pipe 28 is provided with a T-shaped arc groove 12 and a T-shaped slot 13 with the same structure as the surface of the feed pipe 6. At this time, the splicing port 24 is provided with a recycling groove, a limiting shaft arm 15, a torsion spring shaft 16 and a T-shaped block 14, which are the same as those inside the IN feed port 2. Adjacent multi-port ball shafts can be quickly assembled and used by engaging the T-shaped arc groove 12 and the limiting shaft arm 15.

[0061] The assembly of the main valve body 1 with the feed port, the assembly between the multi-way ball seats 25, the assembly between the multi-way connecting seat 18 and the multi-way ball seat 25, and the assembly between the flexible spring tube 20 and the feed port can all adopt the above-mentioned T-shaped arc groove 12 and the locking shaft arm 15 structure to achieve rapid assembly. Specific Implementation Example 4:

[0063] like Figure 1-17 As shown, based on the content of the above specific embodiments, the following content is further disclosed:

[0064] When the main valve body 1 is used for material guiding, the hierarchical structure is selected and assembled according to the scenario, as detailed below:

[0065] When multiple outlets are required, the end of the multi-port ball seat 25 can be directly connected to the IN inlet 2 or other inlets. Taking the IN inlet 2 as an example, the multi-port ball seat 25 is used to distribute materials at different levels through the diversion port 26. The direction and rate of flow are controlled by controlling the opening and closing of the sealing valve 27. One or more multi-port ball seats 25 can be selected for assembly as needed. Multiple multi-port ball seats 25 can be used in a horizontal direction to prevent pipeline accumulation during connection and facilitate pipeline maintenance.

[0066] When multiple channels and outlets are required, according to the content of the above specific embodiment one, the multiple channel connector 18 and multiple channel ball seat 25 are assembled and used. The material is discharged through multiple material ports on the surface of the main valve body 1 connected by the flexible spring tube 20, and the material is discharged through multiple channels through the diversion ports 26 of multiple multiple channel ball seats 25 connected to the surface. Specific Implementation Example 5:

[0068] like Figure 1-17 As shown, based on the content of the above specific embodiments, the following content is further disclosed:

[0069] In the design of multi-port ball seat 25, the flow dividers 26 on the surface are generally added one by one. The flow dividers 26 on the surface of the next multi-port ball seat 25 are added with new dimensions and positions based on the dimensions and number of the previous multi-port ball seat 25's flow dividers 26. For example... Figure 5 As shown, a diversion port 26 is provided on the surface of the multi-pass ball seat 25 near the T-shaped arc groove 12. The diversion port 26 on the surface of the next multi-pass ball seat 25 is based on the diversion port 26, with an additional small diversion port 26. The next multi-pass ball seat 25 has four diversion ports 26, and so on. The diversion ports 26 can be set according to a pattern, such as powers of 2, or according to an arithmetic sequence or a geometric sequence. They can also be set and opened directly without any order, so that the size of the opened diversion ports 26 can be adapted to the existing pipe size over a wide range, realizing the adaptability of the discharge to the pipe. Specific Implementation Example Six:

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

[0072] When the entire multi-port ball seat 25 is used for guiding the flow through the diversion port 26, the following two structures can be adopted:

[0073] like Figure 17 As shown, the multi-port ball seat 25 can be equipped with a main pipe that connects to the first connecting pipe 28 and the second set of connecting pipes 30 for use. Multiple branch pipes are set on the side of the main pipe. The branch pipes are connected to the end of the diversion port 26. After the material enters the main pipe, it enters the diversion pipe to realize the diversion of the material. At this time, the sealing valve 27 can be set at the end of the diversion port 26 or at the connection position between the branch pipe and the main pipe to realize the diversion of the material.

[0074] like Figure 16 As shown, the interior of the multi-channel ball seat 25 can be a complete cavity, and several diversion ports 26 are set on the outer surface. A sealing valve 27 is set inside the diversion port 26. When distributing materials, in order to facilitate the material to flow out from each diversion port 26, the material needs to first fill the entire interior of the multi-channel ball seat 25, and then open the sealing valve 27 to discharge the material, so as to realize multi-channel discharge.

[0075] Select the appropriate internal structure of the multi-pass ball seat 25 according to actual usage requirements. Specific Implementation Example 7:

[0077] like Figure 1-17 As shown, based on the content of the above specific embodiments, the following content is further disclosed:

[0078] In actual use, the connection and assembly of each pipe and material port of the main valve body 1 maintains a sealed structure. The flow direction of each channel inside the main valve body 1 can be set in conjunction with the corresponding published technical documents in this field. This application mainly sets the modular, graded quick-release and connection of the main valve body 1. The flow direction of each channel inside can be selected and set according to the actual use scenario and technology.

[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 aforementioned structural features, a highly flexible and efficient material distribution function is achieved. The modular assembly characteristics of the multi-port connector 18 not only allow for the construction of multiple flow guidance paths in different horizontal positions, achieving a highly efficient distribution mode of one port with multiple outlets, but also greatly broaden the adaptability of the fluid distribution valve in complex processes. Furthermore, based on actual material discharge requirements, one or more corresponding outlets can be precisely selected and connected through the convenient connection between the flexible spring tube 20 and the material port of the fluid distribution valve body 1. Combined with the multi-port design of the multi-port ball seat, diverse distribution effects of multiple ports with multiple outlets and multiple ports with one outlet are achieved, fully meeting the stringent requirements for flow distribution under various working conditions. The quick-release structure widely used between components greatly simplifies the assembly process and significantly shortens the time and manpower required for equipment installation, maintenance, and adjustment. This not only effectively improves production efficiency and reduces operation and maintenance costs, but also enhances the reliability and stability of the entire fluid distribution valve in actual industrial applications, providing a highly competitive and innovative solution for material handling and transmission operations in related industries.
