China valve commonly used in various industries as metal valves, metal valves for use has been a century 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, corrosion and other harsh conditions strong demand, mainly in short service life, greatly affected the disclosure of a serious system stability. Traditional metal valves needed from materials, design and manufacturing processes, etc. overhaul. Ceramic materials for industrial valves is a bold and useful innovation. Deformation of ceramic materials is very small, much higher than the metal with a combination of strength, generally composed of ceramic materials crystal ionic radius, and ion price high, a large coordination number, these properties determine the tensile strength of ceramic materials , compressive strength, elastic modulus, hardness and so very high. Ceramic itself, however, the "brittle" and difficult to machine limits its scope of application of the last decade, due to martensitic transformation toughening technology, composite materials and nano-ceramic Branch Technical development of the concept and progress has been made ceramics " brittle, "has been greatly improved, its toughness and strength has been greatly improved, ever-expanding range of applications. In recent years, new ceramic materials in petroleum, chemical, mechanical, and other fields is very active, using ceramic wear resistance, corrosion resistance and wear-resistant corrosion-resistant parts made of metal materials to replace the Department, is an important market in recent years high-tech materials development directions. Product Features: ★ All parts in contact with the media are structural ceramic materials, their chemical stability and high hardness (Rockwell hardness of HRC90), second only to diamond. Therefore, this valve has a very high resistance to abrasion, corrosion, erosion resistance, and good heat insulation, small thermal expansion. ★ ball grinding equipment and processes using advanced manufacturing, high precision ball roundness, surface quality, and the seat of the study, the use of self-lubrication of Zr02 ceramics can be achieved very good sealing performance. ★ completely changed the metal seal valve easy to leak, torque, sealing surface corrosion of the shortcomings of impatience. ★ Ceramics good abrasion resistance, so that the valve durability, high reliability. Long life, is a titanium valves and Monel valve 2-4 times. ★ granular media for high hardness, or soft particles, but there are corrosion medium, the valve is absolutely unmatched advantage, is the only appropriate medium for such valves. Ceramic Valves social and economic benefits: 1. Ceramic valve structure using high-tech new ceramic materials and vulnerable parts of the valve sealing components, valve products increased wear resistance, corrosion protection and sealing, greatly extended the life of the valve. 2. The use of ceramic valves can significantly reduce the number of maintenance and replacement valves, ancillary equipment to improve operating system security, stability, saving equipment repair costs. 3. Ceramic valves can increase the tightness of industrial piping systems, can reduce the maximum disclosure to protect the environment. 4. Manufacture a wide range of raw materials ceramic, low cost, aluminum, carbon, silicon and other common factors can not create superior performance ceramic materials, can save a lot of metal materials and scarce mineral resources. 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, high corrosion, high pressure and harsh conditions, ceramic valve further demonstrates its excellent performance. Ceramic valves to meet the high wear and tear, the use of highly corrosive environment, in particular outstanding feature is the long service life, performance and low cost ceramic valve is far better than other comparable metal valves. With the continuous development of science and technology and progress of, ceramic materials from the formulation, molding, machining and assembly process and other aspects of the technology is more mature and complete, its outstanding performance ceramic valve increasingly recognized by the valve industry professionals . Using the successful experience of manufacturing ceramic valves can also be applied to a wider range of engineering fields. Solar polysilicon special valve (for: gas transportation silica fume) In the delivery of silica fume, silica powder wrapped ball easily, leading to leaks and other problems, silica fume as reasons for the high hardness, the average life of a very short ball. In view of this situation Jintai Merrill Lynch, specializing in developing the right silicon powder Shusongzhuanyong ceramic valve, ceramic using Jiegou strong Nai corrosion, and high corrosion resistance of zirconium alloys Cailiao to Xin Yuan valve above the valve of Shouming door 6 times, to the solar polysilicon silicon powder delivery device management brings an exciting good news!
