Description

Technical Field

[0001] This utility model relates to the field of valve manual controller technology, specifically a valve manual controller with a viewing window. Background Technology

[0002] The valve manual controller is mainly assembled from a worm gear and a clutch device. It relies on the worm gear for transmission, and the clutch device switches between pneumatic, electric, and manual operation. The actuator controls the opening and closing of the device and other connected equipment by rotating a handwheel or handle. Currently, when using this actuator, the exact position and rotation angle range of the connected equipment cannot be determined. Operators cannot see the position and rotation angle range of the driven device, causing difficulties for precise operation. To facilitate user observation of the actuator's rotation angle, a valve manual controller with a viewing window is needed. To solve the above problems, a valve manual controller with a viewing window is proposed. Utility Model Content

[0003] To solve the above-mentioned technical problems, a manual valve controller with a viewing window is provided. This technical solution solves the problem that the actuator cannot determine the rotation angle of the connected equipment during use.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A manual valve controller with a viewing window includes a housing, a main shaft, and a drive worm gear. A housing cover is bolted to the upper end of the housing, and a viewing window is arranged around the middle of the housing cover. Multiple through holes are opened at the upper end of the housing cover. The main shaft is located inside the housing, and the drive worm gear is located on one side of the main shaft. The drive worm gear is located inside the housing, and both ends of the drive worm gear are rotatably connected to the housing.

[0006] Preferably, the drive worm has a threaded groove in the middle, which is threadedly connected to a worm wheel on one side. The worm wheel is located inside the outer casing, with its lower end rotatably connected to the outer casing. The middle part of the worm wheel is fixedly connected to the main shaft, and the drive worm drives the main shaft to rotate through the worm wheel.

[0007] Preferably, a large handwheel is fixedly connected to one end of the drive worm gear, a rotating handle is provided on one side of the large handwheel, and a small handwheel is fixedly connected to the other end of the drive worm gear. Both the large handwheel and the small handwheel can drive the drive worm gear to rotate.

[0008] Preferably, a keyway is provided on the circumference of the spindle.

[0009] Preferably, a plurality of sign fixing holes are provided below the keyway, and the plurality of sign fixing holes are evenly distributed in a circle on the surface of the spindle. The sign fixing holes are used to fix angle signs, and the sign fixing holes are set at the same horizontal height as the visualization window.

[0010] Preferably, the upper end of the housing cover is provided with a visible digital meaning label.

[0011] The advantages of this utility model compared with the prior art are:

[0012] 1. This utility model has a viewing window on the housing cover, which can effectively observe the rotation of the internal spindle from the outside. An angle mark is set on the spindle, and the corresponding angle position can be observed through the viewing window. A digital meaning label with a viewing window is set on the housing cover, which indicates the opening and closing angles corresponding to different angle positions. Operators can easily check the rotation angle range of the spindle, solving the problem of not being able to know the specific position and angle of the equipment during operation.

[0013] 2. The angle sign set in this utility model can change the installation position through the sign fixing hole and can be observed through the viewing window. The manual controller can also be installed on other devices at different angles to facilitate the observation of the device rotation angle, making it suitable for more usage scenarios.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. It is understood that the accompanying drawings are provided for reference and illustration only and are not intended to limit the present utility model. The connection relationships shown in the drawings are only for clear description and do not limit the connection method.

[0020] like Figure 1 As shown, a manual valve controller with a viewing window includes a housing 1, a main shaft 2, and a drive worm gear 3. A housing cover 11 is bolted to the upper end of the housing 1. Both the upper and lower ends of the housing cover 11 are flanged. The upper end of the housing cover 11 has multiple through holes for connection. A viewing window 12 is arranged around the middle of the housing cover 11. The main shaft 2 is located inside the housing 1. The main shaft 2 inside the housing cover 11 can be observed through the viewing window 12. The drive worm gear 3 is located on one side of the main shaft 2. The drive worm gear 3 is located inside the housing 1 and its two ends are rotatably connected to the housing 1.

[0021] Please refer to Figure 2 The drive worm 3 has a threaded groove 31 in the middle, which is threadedly connected to the worm wheel 6 on one side. The worm wheel 6 is located inside the outer shell 1, with its lower end rotatably connected to the outer shell 1 and its middle part fixedly connected to the main shaft 2. The drive worm 3 drives the main shaft 2 to rotate through the worm wheel 6. A large handwheel 4 is fixedly connected to one end of the drive worm 3, and a rotating handle 41 is provided on one side of the large handwheel 4. The large handwheel 4 can be easily rotated by rotating the handle 41. A small handwheel 5 is fixedly connected to the other end of the drive worm 3. Rotating the large handwheel 4 and the small handwheel 5 can drive the drive worm 3 to rotate, which in turn drives the worm wheel 6 and the main shaft 2 to rotate.

[0022] like Figure 1 and 3As shown, a keyway 21 is provided on the periphery of the spindle 2. Multiple sign fixing holes 22 are provided below the keyway 21. These holes are evenly distributed circumferentially on the surface of the spindle 2. The sign fixing holes 22 are used to fix angle signs, which are marked with the opening and closing angle positions. The sign fixing holes 22 are set at the same horizontal height as the visualization window 12, allowing the angle signs to be observed through the visualization window 12. Operators can determine the rotation angle of the driven device. A visible digital meaning sign 13 is provided at the upper end of the housing cover 11. This sign 13 is marked with the opening and closing angles corresponding to different angle positions, and four angle positions are provided for easy reference during operation. Since the device may have different installation angles during use, the angle signs can be repositioned via the sign fixing holes 22 and observed through the visualization window 12, making it suitable for more application scenarios.

[0023] The principle of this utility model is as follows: A visualization window 12 is provided on the housing cover 11 to observe the rotation of the main shaft 2 inside the housing cover 11. An angle mark is fixed on the surface of the main shaft 2 through the mark fixing hole 22. Rotating the large handwheel 4 or the small handwheel 5 can drive the main shaft 2 to rotate through the drive worm gear 3. The corresponding angle position on the angle mark can be observed through the visualization window 12. A viewing window numerical meaning mark 13 is provided on the housing cover 11. The viewing window numerical meaning mark 13 indicates the opening and closing angles corresponding to different angle positions. Operators can easily check the rotation angle range of the main shaft 2.
