[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] The utility model provides the following technical solutions:

[0017] As attached Figure 1As shown, the utility model discloses an axial flow regulating valve body structure, including an assembled valve body, the assembled valve body including an intermediate valve body 1 and a liquid inlet valve body 2 and a liquid outlet valve body 3 arranged on both sides of the intermediate valve body 1, the intermediate valve body 1 and the liquid inlet valve body 2 and the liquid outlet valve body 3 are all detachably connected, a valve cavity 5 is formed in the assembled valve body, a flow guide 4 is arranged in the part of the valve cavity 5 located in the liquid inlet valve body 2, and the flow guide 4 is connected to the inner wall of the liquid inlet valve body 2. Specifically, in this design, by dividing the assembled valve body of the axial flow regulating valve into a detachably connected intermediate valve body 1 and a liquid inlet valve body 2 and a liquid outlet valve body 3 arranged on both sides of the intermediate valve body 1, such a structure is not only convenient for installation and disassembly, but also greatly facilitates maintenance and replacement. As the core component, the intermediate valve body 1 carries the main functions of the regulating valve, such as flow control, pressure regulation, etc., while the liquid inlet valve body 2 and the liquid outlet valve body 3 are responsible for the inflow and outflow of fluid. The detachable connection design between them eliminates the need for complete disassembly when a component needs to be repaired or replaced, significantly reducing maintenance costs and time. The flow guide 4 can guide the fluid to flow along a predetermined path within the valve chamber 5, thereby improving the valve's flow efficiency and reducing eddy currents and energy losses within the valve chamber 5.

[0018] Furthermore, the liquid inlet valve body 2 comprises a main body 6, a liquid inlet portion 7, and a connecting portion 8. The connecting portion 8 and the liquid inlet portion 7 are respectively arranged on both sides of the main body 6. The connecting portion 8 is connected to the intermediate valve body 1. The outer wall of the connecting portion 8 protrudes to form an outer ring portion 9, and the inner wall of the connecting portion 8 protrudes to form an inner ring portion 10. The intermediate valve body 1 is provided with a first outer connecting portion 11 and an inner connecting portion 12 corresponding to the outer ring portion 9 and the inner ring portion 10, respectively. Bolts for connecting the first outer connecting portion 11 and the inner connecting portion 12 are respectively provided on the outer ring portion 9 and the inner ring portion 10. The liquid inlet valve body 2 is detachably connected to the intermediate valve body 1 via the bolts. Specifically, in this embodiment, the main body 6 serves as the main body of the liquid inlet valve body 2, bearing the strength and stability of the entire component. The liquid inlet portion 7 directly faces the fluid inlet, ensuring that the fluid can smoothly enter the valve chamber 5. The connecting portion 8, as the structure between the liquid inlet valve body 2 and the intermediate valve body 1, not only realizes a stable connection between the two, but also provides the possibility of detachable connection through the design of the outer ring portion 9 and the inner ring portion 10. The protruding design of the outer ring portion 9 not only increases the contact area between the connecting portion 8 and the intermediate valve body 1, but also greatly improves the firmness and sealing of the connection through the tightening effect of the bolts. The provision of the inner ring portion 10 further enhances the structural strength of the connecting portion 8. The first outer connecting portion 11 and the inner connecting portion 12 on the intermediate valve body 1 correspond one-to-one with the outer ring portion 9 and the inner ring portion 10 of the liquid inlet valve body 2, and the precise matching of the bolts realizes a seamless connection between the two. This design not only simplifies the installation process, but also makes it easy to separate the liquid inlet valve body 2 from the intermediate valve body 1 when maintenance or replacement is required, greatly reducing the difficulty and cost of maintenance.

[0019] Furthermore, a second external connection portion 14 is provided on one end of the intermediate valve body 1 proximal to the liquid outlet valve body 3, and a liquid outlet connection portion 15 is provided on the liquid outlet valve body 3 corresponding to the second external connection portion 14. The second external connection portion 14 and the liquid outlet connection portion 15 are fixedly connected by bolts. Specifically, in this embodiment, the liquid outlet connection portion 15 on the liquid outlet valve body 3 closely matches the second external connection portion 14, and the bolts provide a secure connection between the two.

[0020] Furthermore, a guide member positioning portion 13 is provided within the liquid inlet valve body 2. The guide member positioning portion 13 is arranged in an annular structure, and a number of positioning vanes 16 are evenly spaced around the periphery of the guide member positioning portion 13. The two ends of the positioning vanes 16 are fixedly connected to the guide member positioning portion 13 and the inner wall of the liquid inlet valve body 2, respectively. The guide member 4 is detachably located at the end of the guide member positioning portion 13 away from the intermediate valve body 1. Specifically, in this embodiment, the design of the guide member positioning portion 13 provides a foundation for the installation and positioning of the guide member 4. The evenly spaced distribution of the positioning vanes 16 not only enhances the overall strength of the guide member positioning portion 13 but also ensures uniform force on the guide member 4 in the fluid, thereby improving its operating efficiency and stability. The tight connection between the positioning vanes 16, the guide member positioning portion 13, and the inner wall of the liquid inlet valve body 2 ensures that the guide member 4 remains stable even in high-speed liquid flow. The detachable design of the guide member 4 undoubtedly greatly facilitates subsequent maintenance and replacement. When the guide member 4 is worn out due to long-term use or needs to be upgraded, the staff only needs to perform simple operations to remove it from the guide member positioning portion 13 for replacement or repair.

[0021] Furthermore, the guide member 4 is provided with a circular arc-shaped cover-like structure, and the arc surface of the guide member 4 is convex toward the side away from the intermediate valve body 1. Specifically, in this embodiment, the circular arc-shaped cover-like structure design enables the guide member 4 to form a smoother transition when the fluid passes through, effectively reducing the fluid resistance and the generation of vortex phenomena. This design not only improves the flow efficiency of the fluid, but also reduces the noise and vibration generated by the fluid impact, thereby improving the operating quality of the entire valve. The arc surface of the guide member 4 protrudes toward the side away from the intermediate valve body 1. This ingenious layout further enhances its guiding effect. When the fluid flows through the guide member 4, it will be guided by its arc surface and flow smoothly in a predetermined direction, effectively avoiding the direct impact of the fluid on the intermediate valve body 1. This layout not only protects the intermediate valve body 1 from damage, but also improves the service life and reliability of the valve.

[0022] Furthermore, a liquid inlet channel connecting the interior of the intermediate valve body 1 and the interior of the liquid inlet valve body 2 is provided between adjacent positioning blades. This structural layout ensures the smooth flow of the fluid, allowing the fluid to enter the intermediate valve body 1 from the liquid inlet valve body 2 without hindrance, thereby maintaining the stable operation state of the entire valve system.

[0023] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
