Performance and Application of Wear Resistant Ceramic Ball Valve
Performance characteristics and application of wear-resistant ceramic ball valve to promote China's various industries commonly used valves for metal valves, metal valves have been used for hundreds of years of history, although the metal valve through the structure and material improvements, but subject to the limitations of the metal material properties, Can not meet the increasingly high wear and tear, strong corrosion and other harsh conditions, mainly reflected in the short service life, serious leakage 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 electric valve 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 Pneumatic butterfly valve one. 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 a very high electric butterfly valve wear, corrosion resistance, erosion resistance, and good insulation, thermal expansion. ★ ball using advanced grinding equipment and technology, ball roundness, high precision, good surface quality, with the gate valve 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 the valve through the control valve, high reliability. Long life, is 2-4 times the titanium alloy valve and Monel valve. ★ For high hardness of the granular media, or there are soft particles but also corrosion of the check valve, 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 wear resistance, corrosion resistance and sealing, greatly extending the use of the valve life. 2. The use of ceramic valves can greatly reduce the number of valve repair and replacement, improve equipment operation system safety, stability, save the ball valve set. 3. The use of ceramic valves can improve the sealing of industrial piping systems, to maximize the solenoid valve, thereby 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 dilute balance valve production resources. Wear-resistant ceramic valve is mainly used in electric power, petroleum, chemical, metallurgy, mining, sewage treatment and other industrial areas, especially face breathing valve wear, 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 valve stop valve technology continues to evolve and progress, ceramic materials From formulating, forming, processing and assembly technology and other aspects of the technology more mature and complete, ceramic valve with its excellent performance has been more recognized by the valve industry. The use of ceramic valve manufacturing valve test can also be extended to a wider range of engineering applications. Solar polysilicon valve (for: gas delivery of silicon powder) In the delivery of silicon powder plunger valve wrapped silicon, resulting in leakage and other issues arise, due to the high hardness of silicon powder, the average life of the valve is very short. Jintai Meilin company level gauge kind of situation, special research and development for the application of special silica fume ceramic valve, the use of structural ceramics, strong corrosion resistance, and high corrosion-resistant zirconium alloy materials, the new valve valve life is higher than The original valve 6 times as much, to the solar polysilicon powder transport equipment management has brought an exciting good news! Features Traps ★ All parts in contact with the media 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 plug valve into the grinding equipment and manufacturing process, ball roundness high precision, good surface quality, with the seat on the research, the use of Zr02 ceramic self-lubrication, can achieve good sealing performance. ★ completely changed the metal seal valve easy to leak, torque, sealing surface impatience insulation valve defects. ★ Ceramic good wear resistance, so that the valve durable and high reliability. Long life, is the titanium valve and Monel valve copper valve -4 times. ★ for high hardness of the granular media, or soft particles but corrosive medium, the absolute superiority of this valve has unparalleled, but also the only suitable for such media valve Keywords
