Riveted valve connecting rod

Riveting valve connecting rod is a relatively professional concept, which involves the connection technology of the internal structure of the valve. In the valve, the connecting rod is usually used to connect different parts to realize the opening, closing or adjustment function of the valve. Riveting is a commonly used connection process, which connects two or more parts firmly together through rivets.

Regarding the riveted valve connecting rod, it can be analyzed from the following aspects:

I. Introduction to riveting technology

Definition: Riveting is a process that uses axial force to press rivets into parts to make them thick and form nail heads, thereby realizing the connection between parts.

History: Riveting technology has a long history, dating back to Egypt in 3000 BC, where it was used to make wooden tools. With the development of technology, modern riveting technology has been widely used in the connection of metal parts.

Working principle: During riveting, tools such as rivets and riveting guns are used to form permanent riveted joints at the connection. When the rivet is pressed into the hole, its material undergoes plastic deformation and is tightly combined with the parts at the connection to achieve a firm connection.

2. Application of riveted valve connecting rods

Structure: In valves, connecting rods may be used to connect valve discs, valve stems and other components to achieve the switching or adjustment functions of valves. When riveting is used to connect connecting rods, the firmness and stability between connecting rods and other components can be ensured.

Advantages:

Firmness: The riveted joint formed by riveting connection has high strength and stability and can withstand large loads and impact forces.

Sealing: Riveting connection can form a tight seal at the connection to prevent medium leakage.

Adaptability: The riveting process is suitable for connecting parts of various materials and shapes, so it has a wide range of application prospects in valve manufacturing.

3. Precautions for riveting valve connecting rods

Material selection: Select suitable rivets and connecting materials according to the working conditions and medium characteristics of the valve to ensure the reliability and durability of the connection.

Process control: Strictly control riveting process parameters such as riveting pressure, rivet length, etc. to ensure that the connection quality meets the design requirements.

Quality inspection: Perform quality inspection on the riveted connecting rod, including appearance inspection, dimension measurement and performance test, etc., to ensure that the connection quality meets the use requirements.

IV. Cases and Examples

In actual applications, the specific structure and connection method of the riveted valve connecting rod may vary depending on factors such as valve type and working conditions. For example, in some special valves, a new riveted valve stem structure may be used to improve the performance and reliability of the valve by optimizing the riveting method and structural design. These new structures may include special rivet shapes, riveting process parameters, and structural design of connecting parts.

In summary, the riveted valve connecting rod is an important connection method in the internal structure of the valve. By reasonably selecting materials, strictly controlling process parameters, and conducting quality inspections, it can be ensured that the connection quality and reliability of the riveted valve connecting rod meet the use requirements. At the same time, with the continuous development and innovation of technology, the application of new riveted valve stem structures will also bring more possibilities to valve manufacturing.
