[0002] The valve sleeve is a core switching component in a hydraulic servo control system, and its performance directly affects the accuracy and stability of the entire control system. Therefore, the machining accuracy of the valve sleeve is of great significance.

[0003] A valve sleeve typically consists of a valve body, a valve core, and simple connecting components. The valve body, as the main structure, provides a flow channel for the fluid; the valve core moves within the valve body, controlling the fluid flow rate by changing its position. During equipment installation and commissioning, adjusting the parameters of the speed control valve sleeve requires repeated adjustments based on specific system requirements and operating conditions. This process is complex, time-consuming, and demands a high level of technical expertise from the commissioning personnel. Furthermore, it is difficult to quickly and accurately change the size of the liquid flow velocity cross-section within a short period, thus affecting the equipment's processing quality and operating efficiency. Therefore, a multi-purpose adjustable speed control valve sleeve is proposed to address these issues. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a multi-purpose adjustable speed control valve sleeve, comprising a valve body 1 and a connecting block 6. A flange 2 is fixedly connected to the outside of the valve body 1, and an adjusting component is installed on the outside of the flange 2. A connecting component is installed at the end of the connecting block 6. The adjusting component includes a fixing frame 14, which is fixedly connected to the outside of the flange 2. A sealing gasket 15 is fixedly connected to the inside of the fixing frame 14, and a housing 3 is threadedly connected to the outside of the fixing frame 14. By rotating the housing 3 in both directions, the position of the sealing gasket 15 can be easily changed, thereby precisely controlling the cross-sectional area of ​​the liquid flow rate and achieving control of the liquid flow rate. By reasonably adjusting the flow rate, the flow rate can be controlled within a suitable range, reducing wear and impact on equipment and pipelines. A bolt 12 is threadedly connected to the inside of the flange 2, and a nut 13 is threadedly connected to the outside of the bolt 12. The bolt 12 and the nut 13 work together to tightly fix the flange 2 together, allowing the valve body 1 to be easily connected to other pipelines or equipment, preventing fluid leakage and enhancing its sealing performance.

[0032] Reference Figure 1 and Figure 2The connecting assembly includes a housing 4, which is placed outside the connecting block 6. A handwheel 5 is threadedly connected to the inside of the housing 4. A connecting pipe 8 is fixedly connected to the inner side of the handwheel 5, and a locking block 11 is fixedly connected to the outer side of the connecting pipe 8. A compression plate 9 is slidably connected to the inner side of the housing 4, and a sealing ring 10 is fixedly connected to the inner side of the housing 4. Rotating the handwheel 5 causes the connecting pipe 8 and the locking block 11 to compress the compression plate 9. During the sliding process, the compression plate 9 compresses the sealing ring 10, causing the sealing ring 10 to undergo elastic deformation, effectively preventing fluid leakage and further enhancing the sealing performance of the connection. The connecting pipe 8 is slidably connected to the inner side of the housing 4, and the locking block 11 is in contact with the compression plate 9. A limit block 7 is fixedly connected to the inner side of the housing 4. The compression plate 9 is in contact with the surface of the sealing ring 10. The connecting block 6 is slidably connected to the inside of the housing 4. The end of the connecting block 6 is in contact with the limiting block 7. The position of the connecting block 6 is limited by the limiting block 7, which facilitates the fixing of the connecting block 6 and allows the liquid to pass through smoothly. By rotating the handwheel 5 at different angles, the degree to which the clamping block 11 pushes the squeezing plate 9 can be controlled, thereby adjusting the degree of sealing to meet the sealing requirements under different working conditions.

[0033] Working principle: The two flanges 2 are installed using bolts 12 and nuts 13 to further securely connect the valve body 1 to other pipelines. By rotating the outer shell 3, the end of the fixing frame 14 is squeezed, which drives the sealing gasket 15 to move into the inner cavity. The liquid flow velocity cross-section becomes smaller. Rotating the outer shell 3 in the opposite direction causes the inner cavity of the outer shell 3 to disengage from the end of the fixing frame 14, releasing the squeezing of the sealing gasket 15. The liquid flow velocity cross-section becomes larger, thereby achieving control of the liquid flow velocity.

[0034] When connecting the valve body 1 to other pipelines, turning the handwheel 5 drives the connecting pipe 8 and the clamping block 11 to squeeze the extrusion plate 9. During the sliding process of the extrusion plate 9, it will squeeze the sealing ring 10, causing the sealing ring 10 to undergo elastic deformation, thereby filling the gap between the connecting block 6 and the pipeline, further enhancing the sealing performance of the connection, effectively preventing fluid leakage, and further enhancing the sealing effect. At the same time, it also tightens the connecting block 6 in a suitable position, realizing the sealing and tightening of the connection components, which facilitates the installation and disassembly of the valve body 1 and other pipelines, as well as the adjustment of the tightness and sealing performance of the connection according to actual needs.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
