Description

Technical Field

[0001] This utility model relates to the field of industrial flow control, and in particular to a spring sheet with optimized mechanical strength suitable for electrical conversion modules. Background Technology

[0002] Valve positioners, classified by structure into pneumatic valve positioners, electro-pneumatic 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] The key component of a valve positioner is the electrical conversion module, whose main function is to convert electrical signals into pneumatic signals. By amplifying the back pressure of the nozzle and controlling the flow, it provides sufficient power to operate the pneumatic control valve. The accuracy, real-time performance, reliability, vibration resistance, and low power consumption of the electrical conversion module directly affect the overall performance of the valve positioner. Designing a superior electrical conversion module is crucial for achieving intelligent valve positioners.

[0004] In the electrical conversion module, the spring plate is used to regulate the gas pressure and flow rate. The closer the spring plate is to the nozzle, the higher the gas pressure and the lower the flow rate; the farther the distance, the lower the pressure and the higher the flow rate. The structure and performance of the spring plate have a significant impact on the regulation performance of the electrical conversion module. To design a high-performance electrical conversion module, the structure of the spring plate must be repeatedly optimized to find the optimal structure.

[0005] Spring sheets are typically cut from a single sheet of thin metal. Three main factors need to be considered during the design process: mechanical strength, processing cost, and elastic modulus. To achieve lower power consumption and higher sensitivity in the electrical conversion module, the elastic modulus needs to be reduced, meaning it should be made as thin and delicate as possible. However, excessive thinness and thinness reduce the spring sheet's mechanical strength, thus affecting the lifespan of the electrical conversion module. Simultaneously, overly complex shapes increase processing time and manufacturing costs. A well-designed spring sheet requires a balance among these three influencing factors. Utility Model Content

[0006] To address the aforementioned problems in the existing technology, this utility model provides a spring sheet with optimized mechanical strength suitable for electrical conversion modules. In the design process, the mechanical strength of the spring sheet is given priority, and each part is designed to be of equal width, thereby effectively improving the mechanical strength of the spring sheet while ensuring that the elastic coefficient meets the requirements.

[0007] The technical solution of this utility model is as follows:

[0008] A spring sheet with optimized mechanical strength suitable for electrical conversion modules, the spring sheet being cut from a thin metal sheet and comprising four parts: an inner ring 1, an outer ring 2, a mounting ring 3, and an elastic strip 4;

[0009] The inner ring 1 is a circular ring structure, and the difference between the outer radius and the inner radius of the inner ring 1 is H;

[0010] The outer ring 2 is a circular ring structure, and an inner ring 1 is provided inside the outer ring 2. The difference between the outer radius and the inner radius of the outer ring 2 is H; the inner radius of the outer ring 2 is greater than the outer radius of the inner ring 1.

[0011] The mounting ring 3 has a through hole in the center and is disposed on the outer edge of the outer ring 2.

[0012] The elastic strip 4 is obtained by scanning an S-shaped path with a line segment of length H, one end of which is connected to the outer edge of the inner ring 1 and the other end of which is connected to the inner edge of the outer ring 2.

[0013] Furthermore, the spring sheet is made of a soft magnetic material.

[0014] Furthermore, the number of mounting rings 3 is 3; the number of elastic strips 4 is 3.

[0015] Furthermore, the thickness of the spring sheet ranges from 0.1mm to 2mm.

[0016] Furthermore, the value of H ranges from 0.5 mm to 10 mm.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] Implementation, for example Figure 1 , 2 As shown, the spring sheet is cut from a 1mm thick soft magnetic material sheet and can be divided into four parts: inner ring 1, outer ring 2, mounting ring 3, and elastic strip 4. The inner ring 1 is a circular ring structure, with a 5mm difference between its outer and inner radii. The outer ring 2 is also a circular ring structure, with a 5mm difference between its outer and inner radii. The inner radius of the outer ring 2 is larger than that of the inner ring 1. The mounting ring 3 has three through holes at its center, located on the outer edge of the outer ring 2. Screws are passed through these through holes to secure the spring sheet.

[0024] The elastic strip 4 is obtained by scanning an S-shaped path with a line segment of 5mm in length, with one end connected to the outer edge of the inner ring 1 and the other end connected to the inner edge of the outer ring 2. There are 3 elastic strips 4.

[0025] The outer ring 2 is fixed by the mounting ring 3, and the inner ring 1 is suspended in the middle by three elastic strips 4. Under the action of electromagnetic force, the elastic strips 4 will deform, causing the inner ring 1 to move up and down along the central axis.

[0026] The inner ring 1, outer ring 2, and elastic strip 4 are all designed with the same width, and all corners are connected with rounded arcs. This ensures that the mechanical strength of the spring sheet is uniform, with no weak points, and stress will not concentrate in a small area when deformation occurs. This design effectively improves the service life of the spring sheet and the electrical conversion module.

They can be applied to various fields suitable for this utility model.
