Electric ceramic ball valve


Product Description

Detailed introduction:
Metal materials, polymer synthetic materials, and ceramic materials are among the three major solid materials of the contemporary era. Among them, advanced ceramics, namely high-tech ceramics, represent the new materials of the 21st century. With their excellent wear resistance, corrosion resistance, and high-temperature thermal shock resistance, they will be applied in a wider range of industrial fields, and ceramic valves are outstanding achievements of this application.
At present, metal valves are commonly used in the production of various industries in China, and their use has a history of over 100 years. Although they have also undergone structural and material improvements, due to the limitations of metal materials themselves, the corrosion and damage of metals have a significant impact on the service life, reliability, and service life of valve wear resistance. The effects of mechanical and corrosive factors on the metal greatly increase the total wear of the contact surface. During the operation of the valve, the frictional surface undergoes wear and damage due to both mechanical and chemical or electrochemical interactions between the metal and the environment. For valves, the complex working climate conditions of their pipelines; The presence of hydrogen sulfide, carbon dioxide, and certain organic acids in media such as oil, natural gas, and reservoir water increases their surface destructive power, leading to rapid loss of working ability.
Chemical corrosion of metals is mainly manifested in temperature, mechanical load of friction parts, stability of sulfides and their acid resistance in lubricating materials, duration of medium contact, catalytic effect of metals on nitriding process, and conversion rate of corrosive substances molecules to metals. Due to the immutability of these factors, the use of metal valves was once in an awkward state. At the same time, the anti-corrosion measures for metal valves are also subject to the required protection period, transportation and storage conditions, valve construction characteristics, and materials.
Metal valves cannot adapt to harsh working conditions such as high wear and tear, and are not susceptible to strong corrosion in power, petroleum, chemical, metallurgical, mining, sewage treatment, etc. At the same time, they have a short service life and serious leakage, greatly affecting the stability of system operation. We must seek a new type of material to replace the awkwardness of metal, especially in the urgent need for complete innovation in materials, design, and manufacturing processes for traditional metal valves. Therefore, the search for anti-corrosion methods and measures in the metal valve industry has become one of the current research topics in the valve industry.
Our company's scientific and technological personnel have successfully developed ceramic valves that have both the wear resistance of metal valves and the excellent corrosion resistance of synthetic material valves.
The characteristics of ceramic materials are that the deformation is very small, and the bonding strength is much higher than that of metal. Generally, the crystal ionic radius of ceramic materials is small, and the ion electrovalence is high, and the coordination number is large. These properties determine that the tensile strength, compressive strength, elastic modulus, hardness, etc. of ceramic materials are very high. However, the "softness" of ceramic itself relative to metal and its difficulty in machining limit its application range. In recent decades, due to the development and progress of martensite transformation toughening technology, composite technology and nano ceramic concept, the "brittleness" of ceramic has been greatly improved, its strength and toughness have been greatly improved, and the scope of reference has continued to expand.
Ceramic valves are mainly used in industrial fields such as power, petroleum, chemical, metallurgy, mining, sewage treatment, etc., especially in the face of harsh working conditions such as high wear, strong corrosion, high temperature, and high pressure, demonstrating their excellent performance. Ceramic ball valves can meet the following characteristics: firstly, they use high-tech new ceramic structural materials to make sealing and vulnerable parts of the valve, improving the wear resistance, corrosion resistance, and sealing performance of the valve product, greatly extending the service life of the valve. Secondly, the use of ceramic valves can greatly reduce the frequency of valve maintenance and replacement, improve the safety and stability of the supporting equipment operation system, reduce the labor intensity of workers, and save equipment repair costs. Once again, the use of ceramic valves can improve the sealing performance of industrial pipeline systems and minimize leakage, which will play a positive role in promoting environmental protection. Finally, there are a wide range of raw materials and low costs for manufacturing ceramics. Using ordinary elements such as aluminum, carbon, and silicon can produce high-performance ceramic materials, which can save a lot of metal materials and rare mineral resources. Ceramic valves are increasingly recognized by industry insiders for their superior performance. Welcome friends to visit our company and negotiate business.
