Description

Technical Field

[0001] This utility model belongs to the field of structural design technology, specifically relating to a structure for connecting two materials in a modular valve. Background Technology

[0002] With technological advancements, valves are increasingly used in various airborne systems, leading to significantly higher demands for lightweight and intelligent valves. However, the miniaturization and weight reduction requirements of these systems necessitate the design of small, lightweight valves to meet these system requirements. Carbon fiber materials have thus become widely used; however, reliable bonding between metal and carbon fiber materials remains a major technical challenge that the industry urgently needs to address. Utility Model Content

[0003] The purpose of this utility model is to propose a structure for modular valves that can fasten two different materials without the need for fasteners such as screws and nuts, and can use more lightweight materials to achieve the weight reduction of airborne valves. It realizes the fastening connection of two materials, namely metal materials and carbon fiber materials. Carbon fiber materials are lighter in weight, which can achieve the goal of weight reduction.

[0004] Technical solution: To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A structure for connecting two materials in a modular valve, the structure comprising a metal flange, a carbon fiber tube, and a carbon fiber ring;

[0006] The metal flange has a groove in the middle for fixing the carbon fiber tube. The carbon fiber tube is made of carbon fiber and can be directly inserted into the flange. The carbon fiber ring is embedded in the metal flange to achieve overall fixation.

[0007] Furthermore, adhesive is filled between the carbon fiber tube and the carbon fiber ring to achieve overall fixation.

[0008] Furthermore, the carbon fiber tube is cylindrical and is directly inserted into the metal flange groove.

[0009] Furthermore, the diameter of the inner groove of the metal flange is 0.5 mm larger than the diameter of the carbon fiber tube, with an interference fit.

[0010] Furthermore, the metal flange and the carbon fiber tube have a conical structure at one end, which facilitates connection to external pipelines.

[0011] Furthermore, the carbon fiber tube is made of carbon fiber and is manufactured by 3D printing.

[0012] The innovation of this invention lies in the simple and effective fastening connection between the two materials. This invention enables valve weight reduction, further reducing system weight and increasing system load capacity. It also facilitates valve miniaturization and promotes intelligent valve design.

[0016] To more clearly illustrate the technical solutions of the embodiments of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings or specific implementation examples. It should be noted that some (but not all) of the disclosed examples are shown in the drawings. In fact, many different examples can be described, and these examples should not be construed as limited to the examples set forth herein. Rather, these examples are described to better demonstrate the positive effects of this utility model, and all aspects not detailed herein are considered to be well-known or conventional techniques in the art.

[0017] like Figure 1 , 2 The diagram shown is a structural schematic of this utility model, which uses two materials: metal and carbon fiber. A specific structure is designed to achieve a tight connection between the two materials, comprising a metal flange 1, a carbon fiber tube 2, a carbon fiber ring 3, and adhesive 4.

[0018] Specifically, the metal flange 1 has a groove in the middle, and the metal flange with the groove is precision machined by a CNC machine tool to fix the carbon fiber tube 2. The carbon fiber tube 2 is made of carbon fiber and is 3D printed. It can be directly inserted into the flange. The carbon fiber ring 3 is embedded in the metal flange and is also 3D printed. The adhesive 4 is applied to the carbon fiber tube 2 and the carbon fiber ring 3. The adhesive is a bonding adhesive that is compatible with carbon fiber.

[0019] In the specific design, the carbon fiber tube 2 is cylindrical and is directly inserted into the metal flange groove.

[0020] In the specific design, the diameter of the inner groove of the metal flange 1 is 0.5mm larger than the diameter of the carbon fiber tube 2, with an interference fit.

[0021] In the specific design, the overall structure has no other accessories, and it achieves rapid fastening through the physical and adhesive connection of several parts.

[0022] This invention involves creating a groove inside a metal flange, embedding two carbon fiber blocks in the groove, and using a carbon fiber tube for the other part. The diameter of the carbon fiber tube is 0.5 mm larger than the diameter of the groove. Both the carbon fiber tube and the carbon fiber blocks are coated with adhesive. The adhesive-coated carbon fiber tube is then inserted into the groove, achieving a tight bond between the carbon fiber tube and the carbon fiber ring, thus realizing a secure connection between the two materials.

[0023] The metal flanges are machined using CNC machining, while the carbon fiber tubes and carbon fiber rings are manufactured using 3D printing. This ensures the integrity and precision of the components and facilitates the connection.

[0024] The overall design process is as follows: 1. Design drawings for metal flanges separately and prepare materials accordingly;

[0025] 2. Perform CNC machining on a CNC machine tool according to the drawings;

[0026] 3. Prepare carbon fiber materials;

[0027] 4. Based on the metal flange drawings, design the carbon fiber tubes and carbon fiber rings.

[0028] 5. Process the carbon fiber tubes and carbon fiber rings using 3D printing according to the drawings;

[0029] 6. Prepare the special adhesive;

[0030] 7. Apply the special adhesive to the carbon fiber tube and carbon fiber ring;

[0031] 8. Insert the carbon fiber ring into the metal flange;

[0032] 9. Insert the carbon fiber tube into the metal flange;

[0033] 10. Let it stand for a while before using.
