When the control valve is actuated, the displacement of the valve stem is fed back to the valve positioning device through a mechanical device, and the valve position status is transmitted to the upper system through an electrical signal;

[0003] After searching, the Chinese patent utility type patent with announcement number: CN202901506U discloses a valve positioning device. The patent records the feedback disk A and feedback disk B, which are characterized in that the feedback disk A has a fixed installation hole in the center, the diameter of the fixed installation hole is larger than the diameter of the valve stem of the regulating valve, and the feedback disk A is also provided with a positioning slot; the feedback disk B has a connecting hole in the center, the connecting hole is consistent with the cross section of the valve positioner positioning rod, and the feedback disk B is also provided with a metal rod, the outer diameter of the metal rod is smaller than the width of the positioning slot on the feedback disk A. When in use, the feedback disk A is sleeved on the regulating valve stem and fixed with screws; the feedback disk B is sleeved on the positioner positioning rod, and the metal rod on the feedback disk B passes through the positioning slot on the feedback disk A. The connection between the metal rod and the positioning slot is realized to realize the connection between the feedback disk A and the feedback disk B, and the position information of the valve stem of the pneumatic regulating valve is transmitted to the control system to operate the regulating valve. The utility model (announcement number: CN202901506U) has the advantages of accurate positioning and convenient installation, and is particularly suitable for the technical solutions of mineral processing plants and chemical plants;

[0004] However, the scheme announcement number is: CN202901506U. There is a technical problem of lack of stabilizing components. During the flow of fluid, especially when the flow rate changes or there is pressure fluctuation, the pipeline will vibrate and impact. Without stabilizing components, such vibration and impact will be directly transmitted to the valve and adjacent pipelines, which may cause wear, loosening or even damage to valve components, shortening the service life of valves and pipelines. In addition, the lack of stabilizing components will cause stress concentration at the pipeline joints, easily causing fatigue cracks and ruptures of the pipeline. In order to solve this technical problem, the utility model proposes a valve positioning device. Summary of the invention
