摘　　要：介绍了超音速风洞大口径蝶阀的配置形式。运用COSMOSFloWorks软件分析了不同结构蝶板及蝶阀不同开度情况下的流场情况。通过在蝶板上增加蒙皮以及在蒙皮上开孔的方式改善了蝶阀的流场,蝶阀配置旁路阀的方式改善了蝶阀的使用工况,从而降低了蝶阀的故障率,延长了蝶阀的使用寿命。The configuration of the large diameter butterfly valve in the supersonic wind tunnel is introduced.Flow fields of the butterfly valve with different structure discs and different valve opening are analyzed by COSMOSFloWorks.The flow field is improved by adding cover for disc and punching on the cover.The worst service condition is avoided by adding bypass valves to butterfly valves,and so the failure rate is reduced and the life is prolonged.
