Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a multi-way valve with a high-precision flow control structure. Background Technology

[0002] A multi-way valve with a high-precision flow control structure is a valve device that can accurately regulate fluid flow and has multiple channels to achieve multi-directional switching and distribution of fluid.

[0003] A search revealed that the publication (announcement) number CN222102873U, entitled "A Multi-Channel Valve," includes a main pipe with a flow control mechanism at one end and a connecting pipe at the other end, which is fixedly connected to the main pipe via a docking mechanism. The docking mechanism includes an insert tube with sealing rings at both ends. This application features a simple structure, convenient operation, improved sealing, and prevention of leakage at the docking point.

[0004] The above technical solution has the following shortcomings;

[0005] In actual use, the fluids described above often contain various impurities, including solid particles and flocculent matter. However, this multi-channel valve has a significant technical defect: its internal structure lacks a dedicated filter assembly, making it unable to effectively filter the fluid entering the valve. When there are many impurities in the fluid, it can easily lead to wear and blockage of critical components inside the valve, such as the valve core and valve seat. This severely affects the valve's control accuracy of fluid flow and direction, shortens the valve's service life, and increases maintenance costs. Furthermore, disassembling and cleaning the filter assembly is extremely inconvenient. In practice, cleaning or replacing the filter assembly requires completely disassembling the valve from the entire pipeline system and sequentially removing multiple complex components. This cumbersome and time-consuming process not only increases the workload of maintenance personnel but may also affect the normal operation of the entire system due to prolonged pipeline interruptions, reducing production efficiency. Utility Model Content

[0007] Therefore, the purpose of this utility model is to provide a multi-way valve with a high-precision flow control structure, which solves the problem that the existing multi-channel valves are prone to wear and blockage of key components due to the lack of filter components, which affects the control accuracy, and that the filter components need to be disassembled and cleaned as a whole valve, which is cumbersome and laborious.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] This utility model discloses a multi-way valve with a high-precision flow control structure.

[0030] This utility model provides, for example Figure 1-4 The multi-way valve shown has a high-precision flow control structure, including a valve body 1, the valve body 1 including a housing 2, a sealing positioning section 3 fixedly connected to one end of the housing 2, a water inlet telescopic section 4 inserted into one end of the sealing positioning section 3, and a snap-fit ​​interface 5 opened on the inner side wall of the sealing positioning section 3, and a conical filter 6 snap-fitted therein.

[0031] A valve seat 7 is fixedly connected to the cavity of housing 2 through an opening, and a valve core 8 is snapped into the valve seat 7. A main motor 9 is fixedly connected to the top of housing 2, and one end of the main motor 9 passes through the side wall of housing 2 and is fixedly connected to the valve core 8. Multiple outlet solenoid valves 10 are fixedly connected to the side wall of housing 2 through multiple openings. A sealing bolt locking sleeve 11 is sleeved on the pipe wall of the sealing positioning section 3. The sealing bolt locking sleeve 11 is threadedly connected to the outer pipe wall of the inlet expansion section 4. A limit locking mechanism is provided between the sealing bolt locking sleeve 11 and the inlet expansion section 4. A linkage controller 12 is fixedly connected to the side wall of housing 2. The plug-in structure of the sealing positioning section 3 and the inlet expansion section 4 allows for flexible assembly and disassembly of the inlet end. The conical filter 6 is snapped into place through the snap-fit ​​interface 5, which can filter the medium entering the valve, intercept impurities to avoid wear or blockage of key components such as valve core 8 and valve seat 7, improve flow control accuracy, and facilitate the individual disassembly of the filter for cleaning. This design eliminates the need for complete valve disassembly, reducing maintenance difficulty. The main motor 9 drives the valve core 8 to rotate precisely within the valve seat 7. Combined with the coordinated control of the solenoid valve 10 at the outlet end by the linkage controller 12, high-precision flow regulation across multiple channels can be achieved. The threaded connection between the sealing bolt locking sleeve 11 and the inlet expansion section 4 enhances the sealing performance between the sealing positioning section 3 and the inlet expansion section 4, preventing media leakage from affecting flow control. The limit locking mechanism further prevents loosening of the connection. The linkage controller 12 can comprehensively control the actions of each component, improving the overall stability and accuracy of the valve's operation. This solves the problem of existing multi-channel valves lacking filter components, leading to easy wear and blockage of key components, affecting control accuracy, and requiring cumbersome and laborious valve disassembly for filter component removal and cleaning.

[0032] To quickly disassemble the inlet expansion joint 4 for cleaning or replacing the cone filter 6, such as Figure 1 , 2As shown in Figure 4, the limiting locking mechanism includes a slide rail 13, a limiting lever 14, a spring 15, an adjusting slide 16, and a limiting slot 17. The two end side walls of the sealing bolt locking sleeve 11 are fixedly connected to the slide rail 13. The limiting lever 14 is slidably connected inside the cavity of the two end slide rails 13. One end of the limiting lever 14 is fixedly connected to a spring 15. The side walls of the two end slide rails 13 are provided with adjusting slides 16. The two end side walls of the water inlet telescopic section 4 are provided with limiting slots 17. The two end limiting levers 14... The other end passes through the slide rail 13 and engages with the corresponding limit latch 17. The spring force of the spring 15 pushes the limit latch 14 to engage with the limit latch 17, which can quickly lock the relative position of the sealing bolt lock sleeve 11 and the water inlet expansion section 4 to prevent the threaded connection from loosening. The limit latch 14 can be released by using the adjustment slide 16 to move it, which facilitates quick disassembly of the water inlet expansion section 4 to clean or replace the cone filter 6. The operation is convenient and efficient and does not require additional tools.

[0033] To significantly improve the sealing performance of the connection between the two, such as Figure 2 and 3 As shown, the sealing positioning section 3 includes a support pipe section 18, and a sealing ring 19 is sleeved on one end of the support pipe section 18. The elastic deformation of the sealing ring 19 fills the gap between the support pipe section 18 and the water inlet expansion section 4, which significantly improves the sealing performance of the connection between the two, prevents the medium from leaking under pressure, ensures the accuracy of valve flow control, and at the same time, the sealing ring 19 can reduce the wear of the connection parts and extend the service life of the components.

[0034] To facilitate the disassembly of the cone filter 6, such as Figure 1-3 As shown, the water inlet telescopic section 4 includes a cylindrical shell 20, with an inner telescopic tube section 21 threadedly connected inside the cavity of the cylindrical shell 20. One end of the inner telescopic tube section 21 is fixedly connected to a sealing threaded seat 22, and one end of the sealing threaded seat 22 has a sealing bayonet 23. The sealing positioning section 3 is inserted into the sealing bayonet 23. By utilizing the threaded connection between the inner telescopic tube section 21 and the cylindrical shell 20, the overall length of the water inlet telescopic section 4 can be rotatably adjusted, facilitating separation from the sealing positioning section 3 during contraction and making it easier to disassemble the cone filter 6. The insertion and cooperation between the sealing bayonet 23 and the sealing positioning section 3 further enhances the sealing and stability of the connection, ensuring smooth media flow.

[0035] To achieve rapid connection between the valve and external pipelines, such as Figure 1 and 2As shown, each outlet solenoid valve 10 is fixedly connected to an outlet connection flange 24 at the other end, and an inlet expansion joint 4 is fixedly connected to an inlet flange 25 at one end. By utilizing the outlet connection flange 24 and the inlet flange 25, the valve can be quickly connected to the external pipeline through the standardized structure of the flange connection. The connection is firm and has good sealing performance, which facilitates later maintenance and replacement and reduces the workload of installation and maintenance.

[0036] To achieve fast locking and unlocking, such as Figure 1 , 2 As shown in Figure 4, the limiting lever 14 includes a limiting slide bar 26. One end of the limiting slide bar 26 is fixedly connected to an elastic locking head 27. A lever 28 is fixedly connected to the side wall of the limiting lever 14. One end of the lever 28 passes through the adjusting slide port 16. The elastic locking head 27 has a certain elastic deformation capability, which can be tightly locked into the limiting slot 17, improving the reliability of locking. The lever 28 makes it easy for the operator to manually move the limiting lever 14 to achieve quick locking and unlocking. The operation is intuitive and labor-saving, improving maintenance efficiency.

[0037] To reduce the deposition and adhesion of impurities, such as Figure 1-4 As shown, the cavity of valve body 1 is provided with a ceramic anti-stick coating. The ceramic anti-stick coating has a smooth surface and excellent anti-adhesion performance, which can reduce the deposition and adhesion of impurities in the medium on the inner walls of the shell 2, valve seat 7, etc., avoid narrowing of the flow channel or jamming of valve core 8 due to scaling, extend the maintenance cycle of the valve, and ensure high precision and long-term stability of flow control.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
