Valve commonly used in various industries in China for the metal valve, the use of metal valves have been hundreds of years of history, although the metal valve through the structure and material improvements, but limited by the properties of metal materials can not meet the increasingly high wear and tear, strong corrosion Such as bad working conditions, mainly reflected in the short service life, a serious leak greatly affected the stability of the system operation. The traditional metal valve urgent need from the material, design and manufacturing processes and other aspects of the radical reform. The application of ceramic materials to industrial valves is a bold and rewarding innovation. Ceramic material deformation is very small, much higher than the metal bonding strength, under normal circumstances the composition of the ceramic material crystal ion radius is small, and the ion price is high, with a large number of coordination, these properties determine the tensile strength of ceramic materials, Compressive strength, elastic modulus, hardness and so on are very high. However, ceramic itself "brittle" and difficult processing limits its scope of application, over the past decade, due to martensitic transformation toughening technology, composite materials technology and nano-ceramic concept of the development and progress have made 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 fields of petroleum, chemical, machinery and other applications is very active, the use of ceramic wear resistance, corrosion resistance made of wear-resistant parts instead of metal parts, is the important high-tech materials market in recent years One of the development direction. Product Features: ★ All parts in contact with the medium are structural ceramic materials, the chemical stability and high hardness (Rockwell hardness HRC90), second only to diamond. Therefore, the valve has high wear resistance, corrosion resistance, erosion resistance, and good insulation, thermal expansion. ★ ball using advanced grinding equipment and technology manufacturing, ball roundness, high precision, good surface quality, with the seat on the research, the use of Zr02 ceramic self-lubrication, can obtain good sealing performance. ★ completely changed the metal hard-sealed ball valve leaks, torque, sealing surface corrosion-resistant shortcomings. ★ Ceramic good wear resistance, so that this valve is durable, high reliability. Long life, titanium alloy valve and Monel valve 2-4 times. ★ For high-hardness granular media, or soft particles but corrosive medium, the valve has an unparalleled absolute advantage, is currently the only suitable medium for such valves. The socio-economic benefits of ceramic valves: 1. Ceramic valves using high-tech new ceramic structural materials produced valve sealing parts and wearing parts, to improve the valve product wear resistance, corrosion resistance and sealing, greatly extending the life of the valve . 2. The use of ceramic valves can greatly reduce the number of valve repair and replacement, improve equipment operation system safety, stability, saving equipment repair costs. 3. The use of ceramic valves can improve the sealing of industrial piping systems, to minimize leakage, thus protecting the environment. 4. The wide range of raw materials used to make ceramics, low cost, with ordinary aluminum, carbon, silicon and other non-prime can produce superior performance of ceramic materials, can save a lot of metal materials and rare mineral resources. Wear-resistant ceramic valve is mainly used in electric power, petroleum, chemical, metallurgy, mining, sewage treatment and other industrial fields, especially in the face of high wear and tear, strong corrosion, high temperature, high pressure and other harsh conditions, ceramic valve also shows its superior performance . Ceramic valve to meet the high wear and tear, the use of highly corrosive environment, especially outstanding feature is the long service life, the cost performance of ceramic valves is far superior to other similar metal valves. With the continuous development and progress of science and technology, ceramic materials from the formulation, molding, processing and assembly technology and other aspects of the technology is more mature and complete, ceramic valves with its excellent performance has been more recognized by the valve industry. The successful experience of using the manufacture of ceramic valves can also be applied to a wider range of engineering applications. In the transportation of silicon powder, the ball is easily wrapped by silicon powder, which leads to the problems of leakage and the like. Because of the high hardness, the service life of the ordinary ball valve is very short. In response to this situation, Jintai Meilin Company specially researched and developed a special ceramic valve for conveying silicon powder, which made use of the strong corrosion resistance of structural ceramics and the high corrosion resistant material of zirconium alloy to make the service life of the new valve higher than that of the original valve 6 Times as much, to the solar polysilicon power transmission equipment management has brought a very exciting good news!
