Technical Field

[0001] This utility model relates to the field of regulating valve technology, and in particular to a regulating valve positioner mounting structure. Background Technology

[0002] Control valve actuators are key components in industrial automation control systems, responsible for driving the valve spool to precisely control process parameters such as flow rate, pressure, and temperature. When installing positioners on control valve actuators, the mounting holes are often made in an oblong shape to facilitate height adjustment. However, due to the weight of the positioner, it is difficult for one person to fix it at the accurate height during installation, requiring multiple people to work together. This results in high manpower demands and low installation efficiency. Summary of the Invention

[0005] The actuator is located on the top of the actuator bracket, the mounting mechanism is located on the actuator bracket, the positioner is fixed on the mounting mechanism, and the adjustment mechanism is located on the actuator bracket for adjusting the position of the mounting mechanism.

[0006] The mounting mechanism includes: a mounting plate and a mounting rod;

[0007] The mounting plate has an adjustment hole at one end and a fixing hole at the other end. One end of the mounting rod passes through the adjustment hole and is connected to the actuator bracket, while the other end is equipped with a limit cap. The mounting plate slides on the mounting rod through the adjustment hole. An adjustment mechanism is set at the first end of the mounting plate to adjust the sliding of the mounting plate on the mounting rod.

Detailed Implementation

[0024] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0025] First, combine Figures 1-7 This invention describes a mounting structure for a regulating valve positioner 5 according to an embodiment of the present invention, used to mount the positioner 5 onto the actuator of the regulating valve.

[0026] like Figures 1-7 As shown, an embodiment of the present invention provides a mounting structure for a regulating valve positioner 5, which includes: a regulating mechanism 3 and a mounting mechanism 4.

[0027] The actuator includes: an actuator 2 and an actuator support 1;

[0028] The actuator 2 is located on the top of the actuator bracket 1, the mounting mechanism 4 is located on the actuator bracket 1, the positioner 5 is fixed on the mounting mechanism 4, and the adjustment mechanism 3 is located on the actuator bracket 1 for adjusting the position of the mounting mechanism 4.

[0029] The mounting mechanism 4 includes: a mounting plate 41 and a mounting rod 42;

[0030] The mounting plate 41 has an adjustment hole at the first end and a fixing hole at the second end. One end of the mounting rod 42 passes through the adjustment hole and is connected to the actuator bracket 1, and the other end is provided with a limit cap. The mounting plate 41 slides on the mounting rod 42 through the adjustment hole. The adjustment mechanism 3 is set at the first end of the mounting plate 41 and is used to adjust the sliding of the mounting plate 41 on the mounting rod 42. The positioner 5 is connected to the mounting plate 41 through the fixing hole.

[0031] This application mounts the positioner 5 onto the mounting plate 41, and then connects the mounting plate 41 to the execution bracket 1 via the mounting rod 42. The mounting plate 41 slides on the mounting rod 42 through the adjustment hole. The relative position of the mounting plate 41 and the mounting rod 42 is adjusted by the adjustment mechanism 3, thereby adjusting the position of the positioner 5. This allows the positioner 5 to be quickly adjusted to the designated position, and the installation of the positioner 5 can be completed quickly. Only one person is needed to complete the installation of the positioner 5, saving manpower and improving the installation efficiency of the positioner 5.

[0032] like Figures 1-7 As shown, the mounting plate 41 is a right-angle plate. One end of the horizontal plate of the mounting plate 41 has an adjustment hole, and one end of the vertical plate of the mounting plate 41 has a fixing hole.

[0033] In this embodiment, the mounting plate 41 can be a right-angle plate or a long plate. The right-angle plate can be used to adjust the relative position of the positioner 5 and the actuator after installation, so that the positioner 5 is on the side or front of the actuator.

[0034] like Figures 5-7 As shown, the adjustment hole is a strip-shaped hole, and at least two mounting rods 42 are provided inside the strip-shaped hole.

[0035] The sliding direction of the mounting plate 41 is restricted by two mounting rods 42, allowing the mounting plate 41 to slide only in a straight line. By adjusting the mounting positions of the two mounting rods 42, the mounting plate 41 can slide laterally, vertically, or diagonally.

[0036] like Figures 5-7 As shown, the adjustment mechanism 3 includes: an adjustment rack 31, an adjustment gear 32, an adjustment shaft 33, and a driving component;

[0037] The adjusting rack 31 is located on the first end of the mounting plate 41, and the adjusting gear 32 is fixed on the adjusting shaft 33. The first end of the adjusting shaft 33 is rotatably connected to the execution bracket 1, and the second end is connected to the driving component. The adjusting rack 31 meshes with the adjusting gear 32.

[0038] The adjusting shaft 33 is driven to rotate by the driving component, which in turn drives the adjusting gear 32 to rotate. Then, the adjusting rack 31 meshes with the adjusting gear 32, which in turn drives the mounting plate 41 to move, thereby adjusting the position of the positioner 5.

[0039] like Figures 5-7 As shown, the driving component is an adjusting motor, and the output end of the adjusting motor is connected to the second end of the adjusting shaft 33. The driving component is an adjusting handle 34, which is fixed to the second end of the adjusting shaft 33.

[0040] In this embodiment, depending on whether manual or electric operation is required, the driving component is an adjusting motor when electric operation is required. The adjusting motor can be located at the first or second end of the adjusting shaft 33. When manual operation is required, the driving component is an adjusting handle 34, which is located at the second end of the adjusting shaft 33, facilitating manual rotation of the adjusting handle 34. The installation of the positioner 5 can be completed by a single person, saving manpower.

[0041] Above, refer to Figures 1-7 According to an embodiment of the present invention, the positioner 5 is installed on the mounting plate 41, and then the mounting plate 41 is connected to the execution bracket 1 by the mounting rod 42. The mounting plate 41 slides on the mounting rod 42 through the adjustment hole. The relative position of the mounting plate 41 and the mounting rod 42 is adjusted by the adjustment mechanism 3, thereby adjusting the position of the positioner 5. This allows the positioner 5 to be quickly adjusted to the designated position. Only one person is needed to complete the installation of the positioner 5, saving manpower and improving the installation efficiency of the positioner 5.
