進口內(nèi)螺紋陶瓷球閥，耐酸堿球閥性能描述 Performance description

內(nèi)螺紋陶瓷球閥（耐酸堿球閥）其核心部件閥芯與閥座采用性能優(yōu)良的剛玉陶瓷或碳化硅陶瓷，經(jīng)1680℃或2200℃超高溫燒結(jié)而成，洛氏硬度HRA高達85°以上，經(jīng)平面磨、外圓磨、快速球磨、球面對研等工序精密加工，確保球芯圓度達到6μm以下，閥芯與幾乎完全貼合的閥座相對旋轉(zhuǎn)實現(xiàn)啟閉，輕扭矩得以精妙展現(xiàn) RETZ The core parts of the internal thread ceramic ball valve (acid and alkali resistant ball valve), the valve core and valve seat, are made of corundum ceramics or silicon carbide ceramics with excellent performance, which are sintered at 1680 ℃ or 2200 ℃ at ultra-high temperature. The Rockwell hardness HRA is above 85 °, and the roundness of the ball core is ensured to reach 6 by precision processing such as surface grinding, external 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.
