(耐磨，耐酸堿)進(jìn)口氣動(dòng)陶瓷球閥核心部件閥芯與閥座采用氧化鋁陶瓷或碳化硅陶瓷，經(jīng)平面磨、外圓磨、快速球磨、球面對(duì)研等工序精密加工，閥芯與幾乎完全貼合的閥座相對(duì)旋轉(zhuǎn)實(shí)現(xiàn)啟閉，輕扭矩得以精妙展現(xiàn)(Wear resistant, acid and alkali resistant) The core components of the imported pneumatic ceramic ball valve, the valve core and valve seat, are made of aluminum oxide ceramics or silicon carbide ceramics. After precision processing of surface grinding, cylindrical grinding, rapid ball grinding, ball surface grinding and other processes, the valve core and the almost completely fitted valve seat rotate relatively to realize opening and closing, and the light torque is subtly displayed
進(jìn)口氣動(dòng)陶瓷球閥產(chǎn)品詳情 Product details
(球及閥座原料采用剛玉陶瓷（成分為Al，O≥95%）或碳化硅 The material of ball and valve seat is Corundum Ceramic(Main content Al,O.≥95%)or Silicon Carbide
陶瓷經(jīng)1680℃以上超高溫?zé)Y(jié)而成，硬度高達(dá)HRA85° Ceramic is fritted at 1680℃, hardness is up to HRA85°
毛坯經(jīng)過(guò)精密的研磨成型，研磨后的球度為0.005mm Semifinished product is grinded precisely. The sphericity after grinding is 5um
閥芯球體與球座配合研磨，輕扭矩與硬密封完美結(jié)合 The ceramic ball and seat are grinded in pair which makes it have the advantage of low torque and good hard sealing
閥體通過(guò)CNC機(jī)床精密加工，與陶瓷球芯準(zhǔn)確配合 The valve body is precisely processed by CNC machine tool, and accurately matched with the ceramic ball core
產(chǎn)品嚴(yán)格通過(guò)嚴(yán)格的氣壓密封測(cè)試和水壓密封測(cè)試 of the products have passed the strict air pressure seal test and water pressure seal test
