美國泰樂TYLER進(jìn)口高性能三偏心硬密封蝶閥
產(chǎn)品描述-
美國泰樂TYLER進(jìn)口高性能三偏心硬密封蝶閥為偏心金屬密封結(jié)構(gòu),密封形式是金屬對金屬密封,圓盤形蝶板繞著軸線旋轉(zhuǎn)，旋轉(zhuǎn)角度為0°~90°之間來完成開關(guān)及調(diào)節(jié)。
結(jié)構(gòu)原理-
閥板與閥座的密封面為斜圓錐結(jié)構(gòu)，固定在調(diào)節(jié)環(huán)壓板之間的彈簧與壓板上調(diào)節(jié)螺栓裝配一起的結(jié)構(gòu),閥板的密封面與閥座之間的密封是靠傳動裝置的力矩使閥板壓向閥座,這種結(jié)構(gòu)有效地補(bǔ)償了軸套與閥體之間的公差帶及閥桿在介質(zhì)壓力下的彈性變形，解決了閥門在雙向互換的介質(zhì)輸送過程中存在的密封問題
產(chǎn)品特點-
低扭矩,操作靈活；
流通性能好;
無泄漏,開關(guān)迅速;
采用偏心結(jié)構(gòu),閥座與蝶板無乎無磨擦;
具有越關(guān)越緊的密封功能;
密封圈選用不銹鋼制作，具有金屬硬密封和彈性密封的雙重優(yōu)點;
應(yīng)用范圍-
適合于高速流體，高溫流體，低溫流體的管道上主要起切斷和節(jié)流用,產(chǎn)品涉及到造紙、石化、化工、冶金、電力、制藥、化肥、環(huán)保、石油、廢氣凈化裝置、燃?xì)狻⒄羝O(shè)備、造船業(yè)、輕工等工業(yè)部門的自動化控制系統(tǒng)中。
