进口气动内螺纹陶瓷球阀产品详情 Product details
(氧化铝，碳化硅)进口气动内螺纹陶瓷球阀其核心部件阀芯与阀座采用性能优良的刚玉陶瓷或碳化硅陶瓷，经1680℃或2200℃超高温烧结而成，洛氏硬度HRA高达85°以上，经平面磨、外圆磨、快速球磨、球面对研等工序精密加工，确保球芯圆度达到6μm以下，阀芯与几乎完全贴合的阀座相对旋转实现启闭，轻扭矩得以精妙展现 RETZ (Aluminum oxide, silicon carbide) imported pneumatic internal thread ceramic ball valve. Its core parts, valve core and valve seat, are made of corundum ceramics or silicon carbide ceramics with excellent performance. They are sintered at 1680 ℃ or 2200 ℃ at ultra-high temperature. The Rockwell hardness HRA is above 85 °. The roundness of the ball core can be ensured to reach 6 by precision processing such as surface grinding, external circular grinding, rapid ball grinding, ball surface grinding, etc μ Below m, the valve core and the valve seat that almost fit together rotate relatively to realize opening and closing, and the light torque is subtly displayed
