气动陶瓷球阀简介 1. Introduction to Q641TC pneumatic ceramic ball valve

C 气动陶瓷球阀具有优良的耐磨损、耐酸碱、耐腐蚀、高强度、高韧性、耐高温以及防磁性的特点,使其能在特别恶劣的环境中使用,能不污染物料和环境;在管道系列制品可代替不锈钢合金、硬质合金等其他金属制品,并使之成为更优良之制品。 Q641T C pneumatic ceramic ball valve has the characteristics of excellent wear resistance, acid and alkali resistance, corrosion resistance, high strength, high toughness, high temperature resistance and anti-magnetic characteristics, making it able to be used in particularly harsh environments, and can be free of pollutant materials and the environment. ; In the pipeline series products can replace stainless steel alloys, cemented carbide and other metal products, and make it a better product. The original metal or plastic valve ball and valve seat are prone to wear and tear and are not easy to close due to the effects of thermal expansion and contraction, and cannot be effectively used normally, so the service life   Short; this new product, the valve ball and valve seat are made of structural ceramics, and its degree of wear and tear is not affected by the coefficient of thermal expansion and cold, and it has good operability in harsh environments or under fluid Longer life.

气动陶瓷球阀主要特点 Main features of Q641TC pneumatic ceramic ball valve

所有与介质接触的部分均为结构陶瓷材料 其化学稳定性及硬度极高(洛氏硬度 HRC90 仅次于金刚石。 1. All parts in contact with the medium are structural ceramic materials , which have extremely high chemical stability and hardness (Rockwell hardness HRC90 ) , second only to diamond. 本阀具有极高的耐磨损、耐腐蚀、耐冲蚀性能,且隔热性好、热膨胀小。 Therefore , the valve has extremely high wear resistance, corrosion resistance, erosion resistance, good thermal insulation and low thermal expansion.

球体采用先进研磨设备及工艺制造 球圆度精度高 , 表面质量好 与阀座对研后 , 利用 Zr02 陶瓷的自滑润, 彻底改变了金属硬密封球阀易泄露、扭矩大、密封面不耐腐蚀的缺点。 2. The ball is manufactured with advanced grinding equipment and technology . The ball has high roundness accuracy and good surface quality. After being researched with the valve seat , the self-lubricating of Zr02 ceramic is used to completely change the metal hard-sealed ball valve, which is easy to leak, has large torque, and has a sealing surface. The disadvantage of not being resistant to corrosion.

陶瓷良好的耐磨性 让本阀经久耐用 , 可靠性极高 . 使用寿命长 是钛合金阀和蒙乃尔阀的 2-4 倍。 3. The good abrasion resistance of ceramics makes this valve durable and extremely reliable . It has a long service life , which is 2-4 times that of titanium alloy valves and Monel valves .

用于高硬度的颗粒介质,或有软颗粒但又有腐蚀的介质中,本阀门具有无可比拟的绝对优势 4. Used in granular media with high hardness, or in media with soft particles but corrosive, this valve has an incomparable absolute advantage .
