高性能蝶阀 High-performance Butterfly Valve

采用的是上下分段轴，阀板的中间部位没有高高凸起的轴梁，因而减少了阀板开启后在通道中间的阻挡面积。此轴比一般阀轴稍粗，耐压力更强，阀板与轴的连接更稳固。阀座采用的靠背硫化橡胶的技术，当过于干燥的气体和粉体时不易损坏阀座。Adopt the top and bottom section shaft. The middle parts of the valve plate have no raised highbeam of the axis and thus reduce the block area in the middle of channel after opening the valveplate. The shaft is a bit thicker than general valve shaft, and has stronger resistance to pressure.The connection of valve plate and shaft is more stable. The seat uses seat back with vulcanizedrubbe
