wear resistant ZrO2 Zirconia Ceramic valve sleeve bush
Reputation depends on quality, quality comes from Hard!
Ceramic Ball Valve:
The ceramic material has a small deformation amount and a much higher bonding strength than the metal. Generally, the crystal ionic radius of the ceramic material is small, and the ion electricity price is high, and the coordination number is large. These properties determine the tensile strength of the ceramic material, The compressive strength, modulus of elasticity, hardness, and the like are very high. However, the "brittle" and difficult processing of ceramic itself limits its application range. In the past decade, due to the development and progress of martensitic transformation toughening technology, composite technology and nano-ceramic concept, ceramics have been made " The brittleness has been greatly improved, its toughness and strength have been greatly improved, and the scope of application has been continuously expanded. The application of new ceramic materials in petroleum, chemical, machinery and other fields is very active. The use of ceramic wear resistance and corrosion resistance to make wear-resistant and corrosion-resistant parts instead of metal materials is an important development direction of high-tech materials market in recent years. One.
The new ceramic ball valve is a high-tech product independently developed by the new material using structural ceramics with corrosion resistance, wear resistance and high hardness. All parts in contact with the medium are structural ceramic materials with high chemical stability and hardness (Rockwell hardness HRC90), second only to diamond. Therefore, the valve has extremely high wear resistance, corrosion resistance and erosion resistance, and has good heat insulation and small thermal expansion.
· The ball is made of advanced grinding equipment and technology. The ball has high roundness precision and good surface quality. After the valve seat is researched, the self-slip property of Zr02 ceramic can be used to achieve good sealing performance.
· Completely changed the shortcomings of the metal hard seal ball valve that is easy to leak, high torque, and the seal surface is not resistant to corrosion.
· The good wear resistance of the ceramic makes the valve durable and extremely reliable. It has a long service life and is 2-4 times that of the titanium alloy valve and the Monel valve.
· For high-hardness granular media, or media with soft particles but corrosive, this type of valve has an unparalleled absolute advantage and is the only valve suitable for this type of media.
