China valves commonly used in industry for metal valves, metal valve has been the use of the history of a century, although the metal valve through the improvement of structure and materials, subject to the restrictions on the properties of metallic materials, can not meet the increasingly high wear and tear, corrosion, such as strong demand for the poor working conditions, mainly reflected in the life of a short, serious leaks have greatly affected the stability of system operation. In urgent need of the traditional metal valves from the materials, design and manufacturing process innovation and so thorough.
Ceramic materials to be used in the industrial valve 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 under the crystal ionic radius of the small and high-ion price, with the median, and these determine the nature of the tensile strength of ceramic materials strength, compressive strength, elastic modulus, hardness, etc. is very high. Ceramic itself, however the "brittle" and difficult-to-machine limited its scope of application, over the past decade over the past few years, as a result of martensitic transformation toughening technology, composite materials technology and nano-ceramic Section the concept of development and progress, has made ceramics " brittleness "have been greatly improved, and its toughness and strength has been greatly improved, expanding the scope of application.
In recent years, new types of ceramic materials in petroleum, chemical, and mechanical applications, such as very active using the wear resistance of ceramics, the production of wear-resistant Corrosion resistant parts of the Department in lieu of metal materials, high-tech materials in recent years the importance of market One direction of development.
Product performance characteristics:
★ all contacts with the media are part of the structure of ceramic materials, their chemical stability and high hardness (Rockwell hardness HRC90), second only to diamond. Therefore, this ball valve has a very high wear resistance, corrosion resistance, erosion-resistant performance, and good heat insulation, small thermal expansion.
★ ball grinding equipment and the use of advanced manufacturing technology, high accuracy ball roundness, surface quality, and the seat of the inquiry, the use of self-Zr02 ceramic lubricants, and can obtain good sealing performance.
★ completely changed the hard metal sealing ball valve easily leak, torque, and sealing surface corrosion of the shortcomings of intolerance.
★ good wear resistance of ceramic, so that the valve is durable, extremely high reliability. Life long monel titanium valves and valve 2-4 times.
★ for high hardness of the granular media, or the soft particles and corrosion medium, the valve is absolutely unmatched advantages, is the only appropriate medium for such valves.
Social and economic benefits of ceramic valves:
1. Ceramic valve structure using high-tech ceramic materials new valve sealing components and vulnerable parts of the valve products to improve resistance to abrasion, corrosion and sealing, greatly extended the life of the valve.
2. The use of ceramic valves can significantly reduce the number of valve replacement maintenance, equipment operation to improve security and stability, saving the cost of repairing equipment.
3. The use of ceramic valves can improve the sealing of industrial piping systems, to reduce the maximum leakage, thereby protecting the environment.
4. To create a wide range of ceramic raw materials, low-cost, aluminum, carbon, silicon and other non-Su-general will be able to create superior performance ceramic materials, can save a large number of rare metal materials and 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 and tear, strong corrosion, high temperature, high pressure, such as poor working conditions, ceramic valve showed its excellent performance. Ceramic valves to meet the high wear and tear, the use of strong corrosive environment, in particular, is a prominent feature of the ultra-long life, ceramic valves are far superior to other similar cost-effective metal valve. With the continuous development of science and technology and progress of, ceramic materials from the formulation, molding, machining and assembly process technology and other more mature and complete, ceramic valves for its excellent performance has been a growing recognition of the valve industry . Manufacture of ceramics using the successful experience of the valve can also be used to promote a wider range of engineering fields.
Dedicated polysilicon solar valve (for: gas transmission silica fume)
In the delivery of silica fume, the silica coated ball easily, resulting in the emergence of such issues as disclosure, silica fume due to the reasons for the high hardness, the average life of a very short ball valve.
Merrill Lynch & Co., Kim Tae-view of this situation, the application of specialized research and development of the dedicated transmission silica ceramic valves, the use of structural ceramics with strong corrosion resistance, as well as the high zirconium alloys resistant materials, so that the new life of the valve is higher than the original valve 6 times the door to the polycrystalline silicon solar energy transmission device management silica fume has brought an exciting good news!
