New Ball Valves with Welding Connection Revolutionize Industrial Pipelines

In the petroleum, chemical, electric power and other industrial fields, the pipeline system is an indispensable part. As a control device in the pipeline system, the performance of the valve directly affects the safety, stability and efficiency of the entire industrial production. As a common type of valve, ball valves have been widely used in industrial pipelines due to their simple structure, good sealing performance, fast opening and closing, and long service life. The two-piece ball valve connected by welding has become the first choice for industrial pipeline control equipment due to its unique structural design and connection method.

I. Design features of two-piece ball valves connected by welding

1. Structural design

The two-piece ball valve connected by welding is mainly composed of valve body, valve seat, ball, valve stem, sealing ring, transmission device and other components. Compared with general ball valves, its main design features are as follows:

(1) The valve body and valve seat adopt a two-piece structure, which is easy to install and maintain.

(2) The ball is integrally forged, with high strength, wear resistance and impact resistance.

(3) The valve stem adopts an anti-blowout design to ensure safe and reliable operation under high pressure environment.

(4) The sealing ring is made of imported materials and has good sealing performance and temperature resistance.

2. Performance characteristics

(1) Good sealing performance: The valve seat adopts a V-shaped sealing ring, which has a self-tightening function and excellent sealing performance.

(2) Rapid opening and closing: The ball can be fully opened or fully closed by rotating 90 degrees, and the opening and closing time is short.

(3) Long service life: The key components such as the ball and valve seat are made of high-quality materials, which are wear-resistant and have a long service life.

(4) Wide range of applications: It can be used for water, steam, oil, acid and alkali and other media, with a temperature range of -196℃~550℃.

(5) Easy installation: The welding connection method simplifies the installation process and improves the reliability of the pipeline system.

II. Application of two-piece ball valves with welding connection in industrial pipelines

1. Petrochemical field

In the field of petrochemicals, two-piece ball valves with welding connection are widely used in various pipeline systems, such as crude oil transportation, natural gas transportation, refineries, etc. Its superior sealing performance, fast opening and closing capability, and corrosion resistance provide strong guarantees for safe production in the petrochemical industry.

2. Power field

In the power field, welded two-piece ball valves are mainly used in high-temperature and high-pressure pipeline systems such as thermal power plants and nuclear power plants. Its high strength, wear resistance, and impact resistance ensure the efficient and stable operation of the power system.

3. Urban water supply and drainage field

In the field of urban water supply and drainage, welded two-piece ball valves are used in water sources, water pipelines, sewage treatment plants and other occasions. Its good sealing performance and corrosion resistance effectively prevent water waste and pollution.

4. Other fields

In addition, welded two-piece ball valves are also widely used in metallurgy, papermaking, pharmaceuticals, food and other industries, providing efficient and reliable fluid control for various pipeline systems.

III. Conclusion

The welded two-piece ball valve plays an important role in industrial pipelines due to its unique design features. Its superior sealing performance, fast opening and closing capability, wear resistance and impact resistance provide strong guarantees for industrial production. With the continuous development of the industrial field, the two-piece ball valve with welding connection will be more widely used. This article aims to provide new knowledge for industry insiders and promote its wide application in the industrial field through an in-depth analysis of this type of ball valve.
