In the petrochemical industry, ball valves, as a key fluid control device, are widely used in various complex working conditions. Its sealing performance is directly related to the safety, efficiency and environmental protection of production. In recent years, with the continuous improvement of requirements for equipment reliability and safety in the petrochemical industry, significant breakthroughs have been made in the sealing technology of high-performance ball valves, providing strong support for the stable development of the industry.
Key breakthroughs in high-performance ball valve sealing technology
Application of new sealing materials. Sealing materials are one of the core factors affecting the sealing performance of ball valves. Traditional sealing materials such as rubber and polytetrafluoroethylene are prone to aging, deformation or corrosion in environments with high temperature, high pressure and strong corrosive media, leading to sealing failure. To overcome these difficulties, high-performance ball valves begin to use new sealing materials such as flexible graphite, carbon fiber reinforced composite materials and high-performance engineering plastics.
Innovation of bidirectional sealing structure.
Most traditional ball valves adopt one-way sealing design and cannot meet the sealing requirements of bidirectional flowing media in the petrochemical industry. In recent years, bidirectional sealing technology has become an important development direction of high-performance ball valves. By optimizing the valve seat structure and sealing surface design, bidirectional sealing ball valves can maintain good sealing performance when the medium flows in both forward and reverse directions.
Application in high-temperature and high-pressure conditions
In the petrochemical industry, high-temperature and high-pressure conditions are one of the common challenges. High-performance ball valves can effectively deal with this extreme working condition by adopting new sealing materials and optimizing the sealing structure.
Application in the transportation of strongly corrosive media
There are a large number of strongly corrosive media in the petrochemical industry, such as sulfuric acid, hydrochloric acid, hydrofluoric acid, etc. Traditional ball valves are prone to corrosion and leakage problems in this medium environment. High-performance ball valves can effectively resist the erosion of corrosive media by adopting corrosion-resistant sealing materials and lining technology.
Application in bidirectional flow media
In some petrochemical processes, the flow direction of the medium may change, which puts forward higher requirements for the sealing performance of the ball valve. The bidirectional sealing technology of high-performance ball valves can effectively deal with the challenge of this bidirectional flow medium.
