進口全襯陶瓷球閥，耐磨球閥性能描述 Performance description

全襯陶瓷球閥（耐磨球閥）與介質接觸的部分均為結構陶瓷材料，其化學穩定性及硬度極高（洛氏硬度HRC90），僅次于金剛石。因此，具有極高的耐磨損、耐腐蝕、耐沖蝕性能，且隔熱性好、熱膨脹小。球體采用先進研磨設備及工藝制造，球園度精度高，表面質量好，與閥座對研后，利用ZrO2陶瓷的自潤滑性，可取得很好的密封性能 RETZ The parts of the fully lined ceramic ball valve (wear-resistant ball valve) contacting with the medium are all made of structural ceramic materials, which have very high chemical stability and hardness (Rockwell hardness HRC90), second only to diamond. Therefore, it has extremely high wear resistance, corrosion resistance, erosion resistance, good thermal insulation and small thermal expansion. The ball is manufactured with advanced grinding equipment and technology, with high roundness accuracy and good surface quality. After the ball is grinded with the valve seat, it can obtain good sealing performance by using the self-lubricating property of ZrO2 ceramics
