一、 Introduction

With the gradual introduction of national environmental protection policies, the logistics industry is gradually moving towards the use of LNG (liquid natural gas) in order to achieve fuel conservation and environmental protection. At the same time, the competition in the logistics industry is becoming increasingly fierce, and the operational stability, comfort, and safety of heavy-duty trucks have put forward higher requirements for products. As a result, the stability of heavy-duty truck gas exports has become a hot topic of concern in the logistics industry. In order to solve this problem, metal V-rings have become an important solution and have been increasingly applied.

二、 Design and Manufacturing of Metal V-Rings

A metal V-ring is a sealing structural component, with a structural form similar to a V-shaped elastic body. When external force acts on the ring or the "V" bending angle changes, the V-ring will form pressure within a certain range and transmit it to the surrounding sealing area.

In the gas system of heavy-duty trucks, the most important point of V-rings is that they must be stable and reliable. In the application of gas systems, the design and manufacturing of V-rings must strictly comply with standards to ensure their reliable quality.

The design of the V-ring needs to be adjusted according to the requirements of different heavy-duty trucks to ensure good sealing during the assembly process.

When manufacturing metal V-rings, high-quality metal materials should be used. Generally speaking, materials such as galvanized steel plate, stainless steel plate, hard aluminum, brass, titanium alloy, etc. can be used. Among them, 316L stainless steel has good corrosion resistance and is suitable for the chemical, aerospace, food, and pharmaceutical industries. It is also a commonly used manufacturing material for heavy-duty truck gas systems.

三、 Manufacturing process of metal V-rings

The manufacturing process of metal V-rings directly affects their quality. In general, manufacturing processes include multiple stages such as cutting, forming, and forming.

1. Cutting

In the production of metal V-rings, the first step is to choose good manufacturing materials. Then, develop corresponding molds for different requirements and equipment architectures, and use cutting, mold opening, or sleeve disassembly methods for cutting.

2. Forming

After cutting, the metal plate will be strictly formed according to the requirements of the mold. Firstly, quantitative punching is required to empty the center of the board and form the basic shape of a circular ring. Then, bend and press the edges through the mold to form the final "V" opening shape.

3. Forming

The so-called forming refers to further mechanized processing of V-rings, making them into standard shapes and sizes, and then processing and reinforcing them through processes such as processing, heat treatment, and surface treatment.

四、 The Application of Metal V-Rings in Gas Exports

Metal V-rings are mainly used for sealing gas systems, ensuring that gas does not leak out and playing a good role in difficult to seal situations.

Application principle: The inner side of the V-shaped ring is V-shaped, and the outer side is circular, belonging to an elastic structure. When external pressure acts on the V-ring, the V-ring will shrink, and when the pressure disappears, it can return to its original state. Moreover, during the process of combining with the valve, the V-ring ensures the reliability of the seal.

五、 Performance testing and analysis

In order to verify the performance of metal V-rings in heavy-duty truck gas systems, their performance was tested. Experimental tests have shown that metal V-rings have good reliability and stability, and can continuously maintain their sealing performance during multiple compression and decompression processes. In addition, its ability to withstand pressure is relatively strong, and it can still ensure density under high-intensity pressure.

六、 Conclusion and Outlook

The application of metal V-rings in heavy-duty truck gas systems is an important technology, and its reliability and stability have been verified. In the future, with the development of the industry and technological progress, this technology will further enhance the quality of production, improve the reliability and safety of the entire vehicle
