Ceramic valves have excellent performance

Release time: 2017-09-12

    At present, China's various industries commonly used in the production of valves for the metal valve, the use of metal valves have been a hundred years of history, during which although the structure and materials through the improvement, but by the metal material conditions, more and more unable to adapt High wear, strong corrosion and other harsh conditions. Mainly reflected in the short life, serious leakage, greatly affecting the stability of the system operation. Traditional metal valves urgently need to innovate from materials, design and manufacturing processes. Advanced ceramic materials, as new materials in the twenty-first century, have been valued by more and more scientific workers and have been applied to the production of industrial valves as a bold and rewarding innovation. Ceramic material deformation is very small, much higher than the metal bonding strength, under normal circumstances the composition of ceramic materials, crystal ion radius is small, and the ion electricity price is high, coordination number, these properties determine the ceramic material tensile strength, Compressive strength, elastic modulus, hardness, etc. are very high. However, the ceramic itself "brittle" and difficult to limit its application range, over the past decade, due to martensitic transformation toughening technology, composite materials technology and nano-ceramic technology development and progress, has made the ceramic " Brittle "has been greatly improved, its toughness and strength has been greatly improved, the scope of application continues to expand. In recent years, the new ceramic materials in the field of petroleum, chemical, mechanical and other applications is very active, the use of ceramic wear resistance, corrosion resistance to produce wear-resistant parts of the metal parts instead of metal materials, high-tech materials market in recent years is important One of the direction of development.

    1. The use of high-tech new ceramic structural materials made of valve seals and fragile parts, improve the valve products, wear resistance, corrosion and sealing, greatly extending the service life of the valve;

    2. The use of ceramic valves can greatly reduce the number of valve repair and maintenance, improve the safety of the equipment running system, stability, reduce the labor intensity of workers, saving equipment maintenance costs;

    Wear-resistant ceramic valves are mainly used in electric power, petroleum, chemical, metallurgy, mining, sewage treatment and other industrial fields, especially in the face of high wear, strong corrosion, high temperature, high pressure and other harsh conditions, but also shows its excellent performance. It can meet the high wear and corrosion of the use of the environment, especially highlight the characteristics of long service life, its cost performance is far superior to other similar metal valves. With the continuous development of science and technology and progress, ceramic materials from the formula, molding, processing and assembly technology and other aspects of the technology is more mature and complete, the ceramic valve with its excellent performance more and more people get the identity of the industry. The successful experience of manufacturing ceramic valves can also be used in a wider range of engineering applications.
