HUNTINGTON VACUUM VALVES, BUTTERFLY Patented Butterfly Design Provides Superior Seal 蝶形真空閥，蝶閥， 專(zhuān)利蝴蝶設(shè)計(jì)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(shè)計(jì)為許多高真空應(yīng)用提供了一種可行且經(jīng)濟(jì)的閘閥替代方案。與其他制造商的蝶閥不同，后者只使用節(jié)流板來(lái)限制通過(guò)閥門(mén)開(kāi)口的傳導(dǎo)，亨廷頓的設(shè)計(jì)提供了真空密封的O形密封圈。新的設(shè)計(jì)允許密封板在閥孔內(nèi)“浮動(dòng)”，這樣在關(guān)閉時(shí)，它會(huì)在O形密封圈周?chē)鶆虻膲毫ο戮又?。這種設(shè)計(jì)減少了O形環(huán)的磨損或滾動(dòng)。
