HUNTINGTON VACUUM VALVES, BUTTERFLY Patented Butterfly Design Provides Superior Seal 蝶形真空閥，蝶閥， 專利蝴蝶設計提供卓越密封

butterfly valve design provides a viable and economical alternative to the gate valve for many high vacuum applications. Unlike other manufacturer’s butterfly valves that use only a throttle plate to limit the conductance through the opening of the valve, Huntington’s design provides a vacuum tight O-ring seal. The new design allows the sealing plate to “float” within the valve orifice so that in closing it centers itself with even pressure around the O-ring seal. This design reduces scuffing or rolling of the O-ring.

蝶閥設計為許多高真空應用提供了一種可行且經濟的閘閥替代方案。與其他制造商的蝶閥不同，后者只使用節流板來限制通過閥門開口的傳導，亨廷頓的設計提供了真空密封的O形密封圈。新的設計允許密封板在閥孔內“浮動”，這樣在關閉時，它會在O形密封圈周圍均勻的壓力下居中。這種設計減少了O形環的磨損或滾動。
