Triple eccentric butterfly valves, as the crystallization of the latest valve technology, combine the advantages and avoid the disadvantages of various valves. They are increasingly valued by users and designers, gradually replacing bulky gate valves, ball valves, and globe valves.
Triple eccentric butterfly valves are widely used in various important pipelines in energy power generation, petroleum and other industries.
The processing of the core sealing surface of butterfly valves involves complex eccentric and conical structures. Conventional processing methods use intermittent conical turning and grinding, which is inefficient and causes significant tool and wheel wear.
The turning and grinding control method for sealing components of triple eccentric butterfly valves includes eccentric inner conical holes of valve body, eccentric outer conical surfaces of valve core and upper/lower valve covers, using follow-up turning and grinding control methods.using follow-up turning and grinding control methods.

Innovation
Through in-depth research on machined surface models, multiple core sealing components of butterfly valves are integrated on one machine tool for the first time, completing turning and grinding of various workpieces in one clamping. Advantages
Both turning and grinding use tool-follow-workpiece-rotation control method, achieving continuous tool-workpiece surface contact, extending tool life and improving workpiece surface quality. Efficiency
Compared with conventional intermittent turning and grinding, the follow-up processing method increases efficiency by 700% for valve bodies with 600mm diameter. Convenience
Automated workpiece processing control can be achieved through brief interactive operations based on drawings. |
