Ceramic ball valve with super corrosion resistance, high temperature resistance, wear resistance and erosion resistance and other significant characteristics. Are widely used in petrochemical, metallurgy, paper making, power stations, oil refining and other industries of all kinds of gas, liquid and steam and acid and alkali salt mud conveying system. Coal-fired power plant flue gas desulfurization denitration limewater, limestone slurry, gypsum slurry, coal pneumatic ash of polycrystalline silicon powder pneumatic conveying, metallurgical powder pneumatic conveying, hydrometallurgy of sulfuric acid and the mixture of sand, and other fields. Zirconia ceramic ball valve has a low cost, high running economy and long service life, 2 ~ 4 times that of titanium Industrial Valves) The advantage of. The driving methods of manual, pneumatic, a spring return pneumatic, electric, etc. And can design all kinds of special ceramic valves according to customers' requirements. Suitable for all kinds of acid, alkali, salt liquid, gas medium environment, hard seal valve is especially suitable for with particles, fibrous medium environment. Less variant structural ceramics, tensile strength, compressive strength, hardness is very high. Zirconia ceramic ball valve is 99. 5% high purity alumina ceramic manufacturing, ensure the valve under various conditions are excellent performance. 1, the corrosion resistance of 99. Structure of 5% alumina ceramic chemical inertness is very strong, and does not react with most of the organic and inorganic, also won't pollution medium, for most of the acid and alkali, physical and chemical properties of structure of alumina ceramics are very stable, even if the service performance for many years will not degenerate. 2, wear resistance, 99. 5% alumina ceramics is higher than the hardness of zirconia by 43%, 140% higher than the ceramic hardness, 730% higher than the hardness of stainless steel, achieve HRA88, only lower than diamond, silicon nitride, silicon carbide, and this feature determines the ceramic valves are also very good wear resistance. Characteristics 1, all parts are in contact with the medium structure ceramic materials, the chemical stability and hardness ( Rockwell hardness HRC90) , second only to diamond. Therefore, this valve has a very high wear resistance, corrosion resistance, erosion resistance, good insulating and stays, small thermal expansion. 2, spheres, using advanced grinding equipment and manufacture process, ball roundness of high precision, good surface quality, and the seat of research, using Zr02 ceramics from smooth sex, can achieve good sealing performance. 3, completely changed the metal hard seal ball Industrial Valves is easy to leak, torque and the corrosion resistance of sealing surface defect. 4, the ceramic good abrasion resistance, let this valve are durable, and high reliability, long service life, is the titanium alloy valve and monel valve 2 - 4 times. 5, used for high hardness particle medium, or have soft particles and corrosive medium, this valve has the incomparable absolute advantage, and is suitable of this kind of medium valve.
Mech can also foster research that is more useful and influential in society at large.
