Technical Field
[0001] This utility model relates to the field of valve technology, specifically a fluid pipeline control mechanism. Background Technology
[0002] Pipeline control mechanisms, also known as pipeline valves, are devices used to control the flow of gases, liquids, and gases or liquids containing solid powders in various pipelines and equipment. In the application of control mechanisms, the flow rate is generally controlled by a handle on the valve body. For example, the easy-to-maintain flow control valve proposed in the existing authorization announcement number CN221443317U controls the opening degree of the valve core through a handwheel on the valve cover.
[0003] While the valves described above can control the fluid in the pipeline, their structure requires handwheels, transmission rods, and other components, which occupy a significant amount of radial space during application. This makes them difficult to use in pipelines located in confined spaces. To address these issues, we provide a fluid pipeline control mechanism. Utility Model Content

[0024] Please see Figures 1-5 In this embodiment of the present invention, a fluid pipeline control mechanism includes a valve cylinder 1. One end of the valve cylinder 1 is fixedly connected to a first connecting pipe 4, which communicates with the valve cylinder 1. The other end of the valve cylinder 1 is provided with a second connecting cylinder 9. One end of the second connecting cylinder 9 is fixedly connected to an inner cone valve ring 19. The other end of the valve cylinder 1 is provided with a valve ring connection port 23 that matches the inner cone valve ring 19. A flange 5 is fixedly connected to the second connecting cylinder 9 near the valve cylinder 1. The flange 5 is provided with a fixing component for fixing to the valve cylinder 1. The second connecting cylinder 9 can be easily connected to the pipeline by a threaded connector 6 provided on the first connecting pipe 4 and the second connecting cylinder 9. At the same time, the fixing component can be used to fix the inner cone valve ring 19 to the valve cylinder 1.
[0025] The fixing component includes a plurality of threaded holes 20, which are respectively opened at corresponding positions on the mounting holes of the valve cylinder 1 and the flange 5. Screws 10 are inserted into the mounting holes of the flange 5, and the screws 10 are threadedly connected to the threaded holes 20. An annular sealing gasket is provided on the side of the flange 5 that contacts the valve cylinder 1. The flange 5 can be fixed to the end face of the valve cylinder 1 by means of the screws 10 and the threaded holes 20. At the same time, the annular sealing gasket can ensure the sealing after connection. Since the connection is made by screws 10, disassembly is also very convenient. Therefore, it is convenient to inspect the inside of the valve cylinder 1, which is practical and convenient.
[0026] Both the second connecting cylinder 9 and the first connecting pipe 4 have threaded connectors 6 at their ends away from the valve cylinder 1. A positioning slide 17 is fixedly connected inside the valve cylinder 1, and a sliding rod 11 is slidably connected inside the positioning slide 17. One end of the sliding rod 11 is fixedly connected to a conical valve core 18 that matches the inner conical valve ring 19. A sealing assembly is provided on the conical valve core 18. The sealing assembly includes two sealing ring grooves 21, which are formed on the conical surface of the conical valve core 18. A sealing ring 22 is provided in each of the two sealing ring grooves 21. The sealing rings 22 can improve the sealing performance when the conical valve core 18 and the inner conical valve ring 19 are closed, ensuring that no fluid leakage occurs when the inner conical valve ring 19 and the conical valve core 18 are in contact.
[0027] The valve cylinder 1 is also provided with a control component for controlling the opening of the conical valve core 18; the control component includes a tailstock 12, which is fixedly connected to the end of the sliding rod 11 away from the conical valve core 18. Adjusting guide rods 16 are fixedly connected to both ends of the tailstock 12. Sealing sleeves 13 are fixedly connected to both the upper and lower ends of the valve cylinder 1 on the side away from the valve ring connection port 23. The two adjusting guide rods 16 are slidably connected to the sealing sleeves 13 respectively. An outer sleeve 3 is fixedly connected to the end of the adjusting guide rod 16 away from the valve ring connection port 23. The outer sleeve 3 is slidably connected to the valve cylinder 1. The first connecting pipe 4 is provided with a control component for controlling the opening of the conical valve core 18. An adjusting component for adjusting the position of the outer sleeve 3; the surface of the valve cylinder 1 is provided with a reference scale 8. When controlling the opening of the conical valve core 18, the position of the outer sleeve 3 can be adjusted by the adjusting component. After the position of the outer sleeve 3 is adjusted, the adjusting guide rod 16 can be moved. The movement of the adjusting guide rod 16 can drive the sliding rod 11, the tailstock 12 and the conical valve core 18 to move synchronously, thereby realizing the control of the opening of the conical valve core 18. At the same time, the reference scale 8 provided on the valve cylinder 1 can cooperate with the outer sleeve 3 to form an opening reference, which makes it easy for the staff to understand the opening size of the conical valve core 18 and facilitates the control of the fluid in the pipeline.
[0028] The adjusting assembly includes an adjusting thread 7, which is located at one end of the first connecting pipe 4 near the valve cylinder 1. A threaded ring 2 is threaded onto the adjusting thread 7. A limiting ring groove 14 is formed on the side of the threaded ring 2 near the outer sleeve 3. A limiting protruding ring 15 is fixedly connected to one end of the outer sleeve 3 near the threaded ring 2. The limiting protruding ring 15 is rotatably connected within the limiting ring groove 14. The surface of the threaded ring 2 is provided with several anti-slip protrusions. When adjusting the position of the outer sleeve 3, the threaded ring 2 is rotated to engage with the adjusting thread 7, thereby moving the position of the threaded ring 2. The movement of the threaded ring 2, under the action of the limiting protruding ring 15, drives the outer sleeve 3 to move laterally in sync. The outer sleeve 3 drives the adjusting guide rod 16 to adjust laterally. At the same time, the limiting ring groove 14 and the limiting protruding ring 15 are rotatably connected, so that the rotation of the threaded ring 2 does not affect the outer sleeve 3, allowing the outer sleeve 3 to move only laterally.
[0029] The working principle of this utility model is as follows: In use, the two threaded connectors 6 are first connected to the pipeline. When controlling the fluid in the pipeline, the threaded ring 2 is rotated to make the threaded ring 2 cooperate with the adjusting thread 7, thereby realizing the movement of the position of the threaded ring 2. The movement of the threaded ring 2, under the action of the limiting convex ring 15, drives the outer sleeve 3 to move laterally in sync. The outer sleeve 3 drives the adjusting guide rod 16 to adjust laterally. The movement of the adjusting guide rod 16 can drive the sliding rod 11, the tailstock 12 and the conical valve core 18 to move synchronously, thereby realizing the opening control of the conical valve core 18. At the same time, the reference scale 8 set on the valve cylinder 1 can cooperate with the outer sleeve 3 to form an opening reference, which makes it easy for the staff to understand the opening size of the conical valve core 18.
[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Although this specification describes embodiments, not every embodiment contains only one technical solution. This method of description is merely for clarity.
