產(chǎn)品描述
DT673H-6,DT673H-10,DT673H-16,DT973H-6,DT973H-10,DT373H-16,氣動(dòng)對(duì)夾式彈性硬密封蝶閥
概述
DT673氣動(dòng)對(duì)夾式彈性硬密封蝶閥可用于現(xiàn)場(chǎng)要求空間比較窄、管道距離較短的場(chǎng)合。氣動(dòng)對(duì)夾蝶閥采用一個(gè)“U”型不銹鋼密封圈，該精密的彈性密封圈與經(jīng)過(guò)拋光的蝶板三維偏心接觸，解決了傳統(tǒng)偏心蝶閥在啟閉0°～10°瞬間密封面仍處于滑動(dòng)接觸摩擦的弊病,實(shí)現(xiàn)蝶板在開(kāi)啟瞬間密封面即分離,關(guān)閉接觸即密封的效果,達(dá)到延長(zhǎng)使用壽命、密封性能*佳的目的。氣動(dòng)對(duì)夾蝶閥廣泛地應(yīng)用到冶金、電力、石油、化工、空氣、煤氣、可燃?xì)怏w以及給排水等腐蝕性介質(zhì)的管道上，是調(diào)節(jié)流量和截?cái)嗔黧w的*佳裝置。
特點(diǎn)
氣動(dòng)對(duì)夾蝶閥采用三偏心密封結(jié)構(gòu)，閥座與蝶板幾乎無(wú)磨損，具有越觀越緊的密封功能。
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(diǎn)，無(wú)論在低溫和高溫的情況下，均具有優(yōu)良的密封性能,具有耐腐蝕,使用壽命長(zhǎng)等特點(diǎn)。
碟板密封面采用堆焊鈷基硬質(zhì)合金，密封面耐磨損，使用壽命長(zhǎng)。
大規(guī)格蝶板采用絎架結(jié)構(gòu)，強(qiáng)度高，過(guò)流面積大，流阻小。
本閥具有雙向密封功能，安裝時(shí)不受介質(zhì)流向的限制，也不受空間位置的影響，可在任何方向安裝。
驅(qū)動(dòng)裝置可以多工位（旋轉(zhuǎn)90°或180°）安裝，便于用戶(hù)使用。
