I. Introduction

As an important fluid control equipment, ball valves are widely used in high-pressure fields such as petroleum, chemical industry, and natural gas. In order to meet the needs of high-pressure applications, many improvements have been made in ball valves in terms of structure and materials. This article will deeply explore the adaptability improvement of ball valves in high-pressure applications from multiple angles, with a view to providing useful reference for peers.

2. Optimization of sphere design

Reduce fluid resistance: To meet the flow requirements in high-pressure applications, the ball design should minimize fluid resistance. By optimizing the shape of the sphere and reducing the protruding parts, the fluid resistance can be effectively reduced and the flow coefficient increased.
Enhance the strength of the ball: In high-pressure applications, the ball needs to withstand greater pressure. Therefore, it is necessary to use high-strength materials, such as alloy steel, stainless steel, etc., during design, and conduct precise stress analysis to ensure the safety and reliability of the sphere, gate valve manufacture.

3. Improvement of sealing materials

Choose high-performance sealing materials: In high-pressure applications, the performance of sealing materials is critical. High-performance sealing materials such as polytetrafluoroethylene (PTFE) and polyimide (PI) can be used to ensure sealing performance under high temperature and high pressure.
Optimize the sealing structure: By improving the sealing structure, such as using multi-stage sealing, adding sealing rings, etc., the sealing performance can be improved and internal and external leakage can be prevented, globe valve manufacture.

4. Optimization of valve body structure

Strengthen valve body stiffness: In high-pressure applications, the valve body needs to withstand greater pressure and impact. Therefore, the rigidity of the valve body needs to be strengthened during design to improve its pressure resistance and service life.
Optimize flow channel design: Reasonable flow channel design can reduce fluid resistance and improve flow coefficient. Computer fluid dynamics (CFD) technology can be used to optimize the flow channel design to achieve smooth transition of the fluid and reduce vortex losses.

5. Improvement of executive agencies

Improve actuator accuracy: In high-pressure applications, the accuracy and stability of the actuator have a greater impact on valve performance. High-precision actuators, such as electric actuators, pneumatic actuators, etc., can be selected to achieve precise control.
Enhance the reliability of the actuator: The actuator needs to withstand greater pressure and impact in high-pressure applications. Therefore, high-strength materials must be used during design and precise stress analysis must be performed to ensure the safety and reliability of the actuator, check valve manufacture.

6. Conclusion and outlook

This article conducts an in-depth discussion on the adaptability improvement of ball valves in high-pressure applications, including optimization of ball design, sealing materials, valve body structure and actuator. However, with the continuous development of technology, the adaptability of ball valves in high-pressure applications still faces many challenges.
