Alumina water valve plate can be used in electric power, petroleum, chemical, gold, mining, sewage treatment pipeline and other industrial fields of pipeline ball valve. Water valve ceramic plate as a cut off or put through the pipeline medium, can be suitable for nominal pressure PN1.6~10.0Mpa, working temperature -29~540℃ petroleum, chemical, mining, metallurgy, power industry and other working conditions of the pipeline ball valve. Especially for ash discharge, slag discharge system, discharge, sewage system, its service life than ordinary alloy water valve plate increased more than 10 times, can meet the use of high wear, strong corrosion environment. The details are as follows:
1. All the parts in contact with the medium are structural ceramic materials, whose chemical stability and hardness are very high (Rockwell hardness HRC90), and the hardness is second only to diamond. Therefore, the water valve plate made of ceramic materials has very high wear resistance, corrosion resistance, erosion resistance, good heat insulation and small thermal expansion.
2. Made of alumina ceramic microporous group on the surface of the water valve has good smoothness and self-lubrication, changed the traditional material made of other water valve plates and the mechanism of friction and lubrication of the transmission medium, can achieve good sealing, completely changed the use of traditional water valve is easy to leak, sealing surface corrosion defects.
3. Ceramic good wear resistance, so that the ceramic valve plate durable, high reliability. Long service life, is titanium alloy valve sheet and other traditional materials made of valve sheet 2-4 times.
4 In the pipeline transportation of high hardness granular medium, powder medium or soft particles but corrosive medium, ceramic valve plate has incomparable absolute advantage.
