全衬陶瓷球阀 耐磨球阀

进口全衬陶瓷球阀，耐磨球阀性能描述 Performance description

全衬陶瓷球阀（耐磨球阀）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。因此，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。球体采用先进研磨设备及工艺制造，球园度精度高，表面质量好，与阀座对研后，利用ZrO2陶瓷的自润滑性，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
