Description

Technical Field

[0001] The utility model relates to the technical field of electric valve positioners, in particular to an electric valve positioner which is easy to install and fix. Background Art

[0002] An electric valve positioner is a device used to control the opening of a valve, and is mainly installed on valves in industrial process control systems. The main function of this device is to ensure that the valve can accurately reach and maintain the specific position required by the control system in order to accurately control the flow of fluids such as gas, liquid or steam;

[0003] As shown in the reference case "An electric valve positioner that is easy to fix" announcement number "CN215445252U", the electric valve positioner that is easy to fix is ​​fixed by a fixing plate. When installing and fixing, the fixing plate can easily adjust the position of the electric valve positioner, so that the electric valve positioner can be conveniently fixed;

[0004] However, when the electric valve positioner is being positioned and installed, it often needs to be close to or fixed near the vibration source of moving parts such as pumps or motors. Therefore, it will be affected by the vibration from these devices. Continuous vibration will accelerate the wear of the internal mechanical parts of the valve positioner and affect its service life.

[0005] Therefore, an electric valve positioner that is easy to install and fix is ​​proposed to solve the above problems. Utility Model Content

Continuous vibration will accelerate the wear of the internal mechanical parts of the valve positioner and affect its service life.

[0007] The utility model achieves the above-mentioned purpose through the following technical solutions: an electric valve positioner that is easy to install and fix, comprising: an electric valve positioner, a display screen is fixedly installed on the surface of the electric valve positioner, and a mounting protection mechanism is arranged on one side of the electric valve positioner for protecting the electric valve positioner after installation, wherein the mounting protection mechanism comprises two mounting racks arranged on one side of the electric valve positioner, a mounting assembly is arranged on one side of the mounting rack, and a protection assembly is also arranged on one side of the mounting rack. When the electric valve positioner is installed, it can be quickly installed through the mounting assembly, and after installation, the vibration impact of the mounting rack can be buffered and reduced by the coordinated use of the mounting assembly and the protection assembly, thereby reducing the influence of vibration on the electric valve positioner, thereby extending the service life of the electric valve positioner after installation.

During installation, the two mounting frames can be quickly fixedly installed by threading the connecting holes with the fixed points, and the electric valve positioner can be installed synchronously. After installation, when the vibration is transmitted at the fixed point through the damper, the damper effectively absorbs and reduces the impact of the vibration transmitted to the electric valve positioner, so that the electric valve positioner is more stable during operation.

When the electric valve positioner 1 is installed, it can be quickly installed through the mounting assembly 32, and after installation, the vibration impact of the mounting frame 31 can be buffered and reduced by the coordinated use of the mounting assembly 32 and the protection assembly 33, thereby reducing the influence of vibration on the electric valve positioner 1, thereby extending the service life of the electric valve positioner 1 after installation.

[0024] like Figure 2 and Figure 3As shown, the mounting assembly 32 includes a movable groove 321 opened on the surface of the mounting frame 31, a movable block 322 is slidably installed inside the movable groove 321, a connecting hole 323 is opened on the surface of the movable block 322, dampers 324 are fixedly installed on both sides of the movable block 322, and the two dampers 324 are fixedly connected to the inner wall of the movable groove 321. When installing, the two mounting frames 31 can be quickly fixed and installed by threading through the connecting hole 323 and the fixed point, and the electric valve positioner 1 can be installed synchronously. After installation, when vibration is transmitted at the fixed point through the damper 324, the damper 324 effectively absorbs and reduces the influence of vibration transmitted to the electric valve positioner 1, making the electric valve positioner 1 more stable during operation. The installation component 32 also includes a plurality of first bolts 328 fixedly installed on one side of the electric valve positioner 1. The two mounting frames 31 are fixedly installed with mounting plates 325 on both sides.
