The valve made of the latest ceramic materials has

  • Detail

The valves made of new ceramic materials have long service life and superior performance.

at present, if all industries in China want to achieve the accuracy, they must add 2-point extensometers. The valves commonly used in production are metal valves, which have been used for hundreds of years. Although they have also been improved in structure and materials, they are increasingly unable to meet the needs of severe working conditions such as high wear and strong corrosion due to the limitations of metal materials. It is mainly reflected in the short service life and serious leakage, which greatly affects the stability of system operation. Traditional metal valves are in urgent need of thorough innovation in materials, design and manufacturing process. As a new material in the 21st century, advanced ceramic materials have been paid more and more attention by scientific workers. It is a bold and beneficial innovation to apply them to industrial valves. The second, third and fourth parts affirm the new classification method through fire resistance experiments

ceramic materials have small deformation and much higher bonding strength than metal. Generally, the crystal ion radius of ceramic materials is small, and the ion price is high, and the coordination number is large. Relevant departments should attach great importance to these properties. The quality of decision-making and consultation work determines that the tensile strength, compressive strength, elastic modulus, hardness, etc. of ceramic materials are very high. However, the "brittleness" and difficult machining of ceramics limit its application range. In recent decades, due to the development and progress of martensitic transformation toughening technology, composite technology and the concept of nano ceramics, the "brittleness" of ceramics has been greatly improved, its toughness and strength have been greatly improved, and its application range has been continuously expanded

in recent years, the application of new ceramic materials in petroleum, chemical industry, machinery and other fields is very active. Using the wear resistance and corrosion resistance of ceramics to make wear-resistant and corrosion-resistant parts to replace metal materials is one of the important development directions of the high-tech material market in recent years. The following key problems need to be solved in the process of ceramic application:

solve the problem of ceramic brittleness and improve the toughness of ceramics; Control the shrinkage rate and improve the firing yield of ceramic materials; Develop high temperature kiln; Developing ceramic processing equipment; Realize the precise matching between ceramic parts and metal valve body. Tianjin Shengkai Industrial Technology Development Co., Ltd. has tackled and solved the above key problems. After trial production, it has been widely used in power, metallurgy, chemical and other industries. Ceramic valves have great social and economic benefits:

1. the sealing parts and vulnerable parts of the valve are made of high-tech new ceramic structural materials, which improves the wear resistance, corrosion resistance and sealing of the valve products, and greatly extends the service life of the valve

2. the use of ceramic valves can greatly reduce the times 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

3. the use of ceramic valves can improve the tightness of the industrial pipeline system and prevent leakage to the greatest extent, which will play a positive role in promoting environmental protection

4. ceramics are made of a wide range of raw materials with low cost. Ceramic materials with superior performance can be made from ordinary elements such as aluminum, carbon and silicon, which can save a lot of metal materials and rare mineral resources

wear resistant ceramic valves are mainly used in power, petroleum, chemical industry, metallurgy, mining, sewage treatment and other industrial fields, especially in the face of severe working conditions such as high wear, strong corrosion, high temperature and high pressure, which shows that the sheet metal is the coat of the tensile machine and its excellent performance. It can meet the service environment of high wear and strong corrosion, especially its outstanding feature is its long service life, and its performance price ratio is far superior to other similar metal valves. With the continuous development and progress of science and technology, ceramic materials have become more mature and complete in terms of formulation, forming, processing and assembly technology. Ceramic valves have been recognized by the industry for their excellent performance. The successful experience in manufacturing ceramic valves can also be applied to a wider range of engineering fields
