Therefore, the phrases "in one embodiment," "in some embodiments," or "in some of these embodiments" appear in various places throughout the specification, and not all refer to the same embodiment. Furthermore, in one or more embodiments, a particular feature, structure, or characteristic may be combined in any suitable manner.

[0032] Please refer to Figures 1 to 8 As shown, a valve actuator with a dual display mechanism provided by this utility model will now be described. This valve actuator with a dual display mechanism includes an actuator body 1, a dual display mechanism 2, and an outer casing structure 3. The output end 11 of the actuator body 1 can output torque. The dual display mechanism 2 is mounted on the actuator body 1 and includes an electronic display panel 22 and a mechanical display panel 23. The outer casing structure 3 includes a cover 31 connected to the actuator body 1, a transparent sheet 32 ​​rotatably fitted onto the cover 31, and a pull wire 34. The transparent sheet 32 ​​is positioned... Outside the electronic display panel 22 and the mechanical display panel 23, a pull wire 34 is wound around the periphery of the transparent sheet 32. One end of the pull wire 34 is connected to the transparent sheet 32, and the other end of the pull wire 34 passes through the outside of the cover 31. A wiping body is also provided on the cover 31. The wiping body contacts the inner surface of the transparent sheet 32. Pulling the pull wire 34 can pull the transparent sheet 32 ​​to rotate. When the transparent sheet 32 ​​rotates, the wiping body will rub against the transparent sheet 32, thereby wiping away the adhering substances on the inner surface of the transparent sheet 32, which solves the problem of the observation window being affected by the generation of condensation.

[0033] like Figure 1 As shown, in some embodiments, the dual display mechanism 2 further includes a frame 21, which is connected to the actuator body 1. The electronic display panel 22 is connected to the stroke shaft (not shown) via a connecting gear 221. The stroke shaft is connected to the output end 11, thereby transmitting the rotational motion of the output end 11 to the stroke shaft. The stroke shaft then transmits the stroke of the output end 11 to the electronic display panel 22. The mechanical display panel 23 is connected to the stroke shaft via a connecting gear 231, thereby transmitting the rotational motion of the output end 11 to the mechanical display panel 23. A gear set 232 is provided between the connecting gear 231 and the mechanical display panel 23. The rotational motion of the stroke shaft is speed-adjusted and then transmitted through the gear set 232, which drives the mechanical display panel 23 to rotate.

[0034] In some embodiments, the electronic display panel 22 is an absolute encoder.

[0035] like Figure 4 As shown, in some embodiments, the inner cavity cross-section of the cover 31 is circular, the transparent sheet 32 ​​is a circular structure, and the peripheral sidewall of the transparent sheet 32 ​​is rotatably engaged with the inner cavity sidewall of the cover 31.

[0036] like Figure 7 As shown, in some embodiments, a connection hole 321 is provided on the side wall of the transparent sheet 32, and one end of the pull wire 34 is inserted into and fixed in the connection hole 321.

[0037] like Figure 7 As shown, in some embodiments, a receiving groove 322 extending circumferentially on the peripheral sidewall of the transparent sheet 32 ​​is provided, so that when the pull wire 34 is wound around the periphery of the transparent sheet 32, the pull wire 34 can be put into the receiving groove 322, so that the pull wire 34 will not cause jamming of the peripheral rotation gap of the transparent sheet 32.

[0038] like Figure 5 As shown, in some embodiments, a limiting ring 33 is installed inside the cover 31. The limiting ring 33 abuts against the side of the transparent sheet 32 ​​facing the inside of the cover 31, so that the limiting ring 33 abuts the transparent sheet 32 ​​against the position near the first window 312 and the second window 313, thereby limiting the installation of the transparent sheet 32.

[0039] like Figure 5As shown, in some embodiments, an elastic element 35 is installed on the transparent sheet 32. The elastic element 35 applies a spring force to the transparent sheet 32 ​​to drive it to rotate in a first direction. When the elastic element 35 drives the transparent sheet 32 ​​to rotate in the first direction, the pull wire 34 is wrapped around the periphery of the transparent sheet 32. Thus, when the pull wire 34 is pulled outward from the cover 31, the transparent sheet 32 ​​is driven to rotate in the second direction against the spring force of the elastic element 35. When the pulling force on the pull wire 34 is released, the elastic element 35 drives the transparent sheet 32 ​​to rotate in the first direction through the elastic restoring force. At the same time, the pull wire 34 retracts into the cover 31 and wraps around the periphery of the transparent sheet 32.

[0040] like Figure 5 and Figure 6 As shown, in some embodiments, the inner surface of the transparent sheet 32 ​​is provided with a hook structure 323, one end of the elastic member 35 is connected to the hook structure 323, and the other end of the elastic member 35 is connected to the limiting ring 33. The limiting ring 33 is provided with a limiting groove extending circumferentially, and the hook structure 323 is inserted into the limiting groove. Thus, through the above design, when the transparent sheet 32 ​​rotates, the hook structure 323 can only move along the extension path of the limiting groove, thereby limiting the rotation range of the transparent sheet 32.

[0041] like Figure 4 As shown, in some embodiments, the outer side of the cover 31 is provided with a pull hole 311 that communicates with the inner cavity of the cover 31, and the pull wire 34 passes through the pull hole 311 and exits the outside of the cover 31.

[0042] like Figure 8 As shown, in some embodiments, the end of the pull cord 34 extending to the outside of the housing 31 is fitted with a sealing sleeve 341, so that the sealing sleeve 341 can seal the gap between the pull cord 34 and the pull cord hole 311, preventing external substances from entering the interior of the housing 31 through the pull cord hole 311.

[0043] like Figure 8 As shown, in some embodiments, one end of the pull cord 34 extending outside the housing 31 is provided with a handle 342 so that the operator can pull the pull cord 34 by holding the handle 342.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
