Description

Technical Field

[0001] This utility model relates to the field of valve positioner technology, specifically to a magnetic strip mounting structure for a valve positioner. Background Technology

[0002] Valve positioners, classified by structure into pneumatic valve positioners, electric valve positioners, and intelligent valve positioners, are the main accessories of control valves. They are usually used in conjunction with pneumatic control valves. They receive the output signal from the controller and then use their output signal to control the pneumatic control valve. After the control valve is activated, the displacement of the valve stem is fed back to the valve positioner through a mechanical device, and the valve position status is transmitted to the upper system through an electrical signal.

[0003] However, existing technologies still have the following problems:

[0004] Existing valve positioner magnetic strip mounting structures are mostly inconvenient for adjusting the installation position of the valve positioner and magnetic strip. In actual industrial production scenarios, factory layouts are complex and varied, with various pipelines crisscrossing. Different valve specifications require positioners with different precise positions. Once the traditional installation structure is fixed, it is difficult to change. If the initial installation position is slightly off, subsequent corrections are extremely cumbersome and may even require the removal of many related components, resulting in a significant increase in downtime and seriously affecting production efficiency. Furthermore, the inconvenience of adjustment makes it impossible to adapt to different models of magnetic strips and valve positioners.

[0005] To address the aforementioned problems, the inventors proposed a magnetic strip mounting structure for valve positioners. Utility Model Content

A reinforcing bolt is threaded through the valve positioner mounting plate and the support plate, and a nut is threaded onto the outer surface of the reinforcing bolt. The nut is movably fitted with the support plate.

Detailed Implementation

[0017] 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.

[0018] Example: Figure 1-4 As shown, this utility model provides a magnetic strip mounting structure for a valve positioner, including two base frames 1. A base 2 is bolted between the two base frames 1. A support plate 3 is detachably mounted on the upper surface of the base 2. The support plate 3 is secured to the base 2, and the base 2 and the support plate 3 are bolted together. This design ensures that the support plate 3 maintains a stable position during daily operation. In workshop environments with large machinery operating and slight ground vibrations, this double-fixing method ensures the stability of the overall structural foundation and reduces the risk of component loosening due to vibration. Vertical rods 31 are symmetrically fixed to the outer surface of the support plate 3. One side of one vertical rod 31 has a magnetic strip mounting plate 5, and the other side of the vertical rod 31 has a support plate 41. A valve positioner mounting plate 4 is mounted on one side of the support plate 41, and positioning slots are symmetrically provided on one side of the valve positioner mounting plate 4. 46 and bolt groove 45, and a reinforcing bolt 42 is threadedly connected between the valve positioner mounting plate 4 and the support plate 41. A through-type adjustment groove 44 for use with the reinforcing bolt 42 is symmetrically opened on one side of the support plate 41. A nut 43 is threaded on the outer surface of the reinforcing bolt 42. The nut 43 is movably fitted with the support plate 41. First, the two bottom frames 1 are connected and fixed by bolts, and the base 2 is installed on them. The support plate 3 is detachably clamped on the base 2 and further tightened with bolts to ensure the stability of the overall structure. When installing the valve positioner, the positioning slot 46 on the valve positioner mounting plate 4 is used for initial positioning. Then, the reinforcing bolt 42 is passed through the adjustment groove 44 on the valve positioner mounting plate 4 and the support plate 41 and the nut 43 is tightened to achieve a stable installation of the valve positioner. The adjustment groove 44 can facilitate fine adjustment of the installation position of the valve positioner.

[0019] One of the uprights 31 has an adjusting frame 51 fixedly mounted on one side. A lead screw 52 is rotatably mounted inside the adjusting frame 51. A motor 53 is mounted on one side of the adjusting frame 51. A protective plate is fixedly mounted on one side of the adjusting frame 51 and is fixedly connected to the motor 53, providing effective protection and support for the motor 53. The output end of the motor 53 passes through the adjusting frame 51 and is fixedly connected to the lead screw 52. A moving block 54 is threaded onto the outer surface of the lead screw 52. Slide grooves 56 are symmetrically opened on the upper and lower sides of the adjusting frame 51. Slide strips 57 are symmetrically fixed at the upper and lower ends of the moving block 54, and the slide strips 57 are engaged in the corresponding slide grooves 56. An L-shaped plate 55 is detachably mounted on one side of the moving block 54, and there is a communication channel between the moving block 54 and the L-shaped plate 55. The detachable connection via bolts allows for quick replacement of components when the magnetic strip mounting plate 5 is damaged or when different specifications of magnetic strips need to be replaced. The L-shaped plate 55 is fixedly connected to the magnetic strip mounting plate 5. When the motor 53 operates, its output drives the lead screw 52 to rotate within the adjustment frame 51. Since the lead screw 52 and the moving block 54 are threadedly connected, and the slide bar 57 of the moving block 54 is locked in the slide groove 56 of the adjustment frame 51, the moving block 54 is restricted to moving linearly along the axis of the lead screw 52. As the lead screw 52 rotates, the moving block 54 drives the L-shaped plate 55, which is bolted to it, to move, thereby realizing the position adjustment of the magnetic strip mounting plate 5 and facilitating precise positioning of the magnetic strip installation position according to actual needs.

[0020] Working principle: First, the two base frames 1 are connected and fixed by bolts, and the base 2 is installed on them. The support plate 3 is detachably snapped on the base 2 and further tightened with bolts to ensure the stability of the overall structure. When installing the valve positioner, the positioning slot 46 on the valve positioner mounting plate 4 is used for initial positioning. Then, the reinforcing bolt 42 is passed through the adjustment groove 44 on the valve positioner mounting plate 4 and the support plate 41 and the nut 43 is tightened to achieve a stable installation of the valve positioner. The adjustment groove 44 can facilitate fine adjustment of the installation position of the valve positioner.

[0021] When the motor 53 operates, its output drives the lead screw 52 to rotate within the adjustment frame 51. Since the lead screw 52 and the moving block 54 are connected by a threaded connection, and the slide bar 57 of the moving block 54 is stuck in the slide groove 56 of the adjustment frame 51, the moving block 54 is restricted to moving linearly along the axis of the lead screw 52. As the lead screw 52 rotates, the moving block 54 drives the L-shaped plate 55, which is bolted to it, to move, thereby realizing the position adjustment of the magnetic strip mounting plate 5, which facilitates precise positioning of the magnetic strip installation position according to actual needs.

[0022] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
