| titleOfInvention | A kind of the processing of sphere technique and seal ball-valve of ceramic seal ball-valve |
| abstract | The invention discloses a kind of the processing of sphere technique of ceramic seal ball-valve and seal ball-valves, comprising the following steps: metal zirconium embryo material is processed into the sphere and valve seat of required shape；Zirconium dioxide (ZrO2) ceramic adhesive layer is formed in the outer surface of sphere and valve seat respectively using micro-arc oxidation process；By sphere installation in sphere grinder, and centering sphere center position；Sphere is roughly ground using skive；Valve seat is installed on valve seat tooling, matches and grinds with sphere.The processing of sphere technique of ceramic seal ball-valve provided by the invention, ceramic treatment is carried out using surface of the micro-arc oxidation process to sphere and valve seat, there is the partial mill of micropore to fall ceramics attachment layer surface using polishing and pairing grinding, the sealing surface of sphere and valve seat is set to reach high circularity and finish, standard requirements are fully achieved in the sealing performance of valve, and this technique has processing step simple, production equipment price is low, the low advantage of production cost. |
