Description

Technical Field

[0001] This utility model relates to the field of industrial flow control, and in particular to a spring sheet suitable for optimizing the processing cost of 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 existing technologies, this utility model provides a spring sheet with optimized processing costs suitable for electrical conversion modules. During the design process, the processing cost of the spring sheet is given priority. The groove is cut on a circular thin plate using CNC technology, which can be completed in a single pass, thereby effectively reducing the processing cost 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 processing costs suitable for electrical conversion modules, the spring sheet being cut from a thin metal sheet, the spring sheet comprising a circular plate 1 and a mounting ring 2;

[0009] The outer edge of the circular plate 1 is circular, and a central hole 3 is provided at the center of the circular plate 1.

[0010] The mounting ring 2 has a through hole at its center; the mounting ring 2 is placed on the outer edge of the circular plate 1;

[0011] The top of the circular plate 1 is provided with an elastic groove 4, which is obtained by scanning along an arc with a diameter of D. The arc is an involute. The elastic groove 4 is arranged in a circumferential array with equal spacing about the center of the circular plate 1.

[0012] Furthermore, the spring sheet is made of a soft magnetic material.

[0013] Furthermore, the number of mounting rings 2 is 3; the number of elastic grooves 4 is 3.

[0014] Furthermore, the thickness of the spring sheet is 0.1mm to 2mm.

[0015] Furthermore, the value of D ranges from 0.5 mm to 2 mm.

[0021] 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.

[0022] Implementation, for example Figure 1 , 2As shown, the spring sheet is cut from a 1mm thick sheet of soft magnetic material and can be divided into two parts: a circular plate 1 and a mounting ring 2. The outer edge of the circular plate 1 is circular, and there is a through hole in its center, namely the central hole 3. The mounting ring 2 has a central through hole, and there are 3 such holes on the outer edge of the circular plate 1. The spring sheet can be fixed by passing screws through the through holes of the mounting ring 2.

[0023] Three elastic grooves 4 are provided on the circular plate 1. The elastic grooves 4 are obtained by scanning along an arc with a diameter of 0.5 mm. This arc is an involute, so that one end of the elastic groove 4 is close to the central hole 3 and the other end is close to the outer edge of the circular plate 1. The area between the central hole 3 and the outer edge of the circular plate 1 is divided into strip-shaped structures by the elastic grooves 4. When subjected to electromagnetic force, these strip-shaped structures will deform and move up and down along the central axis of the central hole 3.

[0024] The elastic groove 4 is machined using CNC technology, which can be completed in just one pass, effectively reducing the machining cost.
