1. Introduction

With the continuous development of industrial production technology, the requirements for fluid control equipment are getting higher and higher. In the fields of petroleum, chemical industry, electric power, etc., high temperature and high pressure working conditions pose severe challenges to the performance of valve equipment. As a valve product widely used in harsh working conditions, the reliability of pneumatic welded three-piece ball valves has become the focus of attention of engineering and technical personnel. This paper will conduct a detailed evaluation of the reliability of pneumatic welded three-piece ball valves under high temperature and high pressure environments from the aspects of structure, materials and performance.

2. Structural characteristics of pneumatic welded three-piece ball valves

 2-1. Three-piece structure design

The pneumatic welded three-piece ball valve adopts a three-piece structure design, which is convenient for valve disassembly and maintenance. In high temperature and high pressure environment, this design effectively reduces the stress concentration caused by temperature changes in the valve, and improves the overall strength and reliability of the valve.

 2-2. Welding connection method

The pneumatic welded three-piece ball valve adopts a welding connection method, which is more tightly connected to the pipeline and effectively prevents leakage. In addition, the welding connection has the following advantages:

(1) High pressure resistance: The welding connection can withstand higher pressure and is suitable for high temperature and high pressure conditions.

(2) Good corrosion resistance: The welding connection has good corrosion resistance and can be used in highly corrosive media environments.

(3) Easy installation: The welding connection simplifies the installation process and reduces engineering costs.

3. Material selection of pneumatic welded three-piece ball valve

 3-1. Valve body material

In high temperature and high pressure environment, the selection of valve body material is crucial. Pneumatic welded three-piece ball valves usually use high temperature and high pressure materials such as stainless steel and alloy steel, which have good corrosion resistance and high temperature strength.

 3-2. Ball material

The ball is a key component of the ball valve, and the choice of its material directly affects the sealing performance and durability of the valve. Pneumatic welded three-piece ball valves use wear-resistant materials such as carbide and ceramics to ensure the reliability and service life of the valve under high temperature and high pressure environments.

4. Performance advantages of pneumatic welded three-piece ball valves

 4-1. Good sealing performance

The pneumatic welded three-piece ball valve adopts a floating ball structure to achieve a close fit between the valve seat and the ball, effectively reducing the leakage rate. Under high temperature and high pressure conditions, its sealing performance is excellent.

 4-2. High temperature and high pressure bearing capacity

The pneumatic welded three-piece ball valve is made of high temperature and high pressure materials, which can withstand high temperatures and pressures and is suitable for harsh working conditions.

 4-3. Easy to operate

The pneumatic welded three-piece ball valve uses a pneumatic actuator to achieve remote control of the valve and reduce the labor intensity of the operator. At the same time, the pneumatic actuator has the advantages of fast response speed and high control accuracy.

5. Conclusion

Through an in-depth evaluation of the structure, materials and performance of the pneumatic welded three-piece ball valve, this paper draws the following conclusions:

 5-1. The pneumatic welded three-piece ball valve adopts a three-piece structural design and welding connection method, which has the characteristics of strong structure and resistance to high temperature and high pressure.

 5-2. The valve body and ball are made of high temperature and high pressure materials and wear-resistant materials to ensure the reliability and service life of the valve under harsh working conditions.

 5-3. The pneumatic welded three-piece ball valve has good sealing performance, high temperature and high pressure bearing capacity and easy operation, and has a wide range of application prospects under harsh working conditions.

In short, the reliability of the pneumatic welded three-piece ball valve under harsh working conditions has been fully verified, providing a strong guarantee for industrial production. In practical applications, the pneumatic welded three-piece ball valve should be reasonably selected and configured according to the working conditions and medium characteristics to ensure its stable operation under high temperature and high pressure environment.
