電動(dòng)通風(fēng)蝶閥采用鋼板焊接制造，具有結(jié)構(gòu)尺寸短，重量輕，安裝方便等特點(diǎn)。該閥驅(qū)動(dòng)力矩小，啟閉靈活，操作方便。閥體上設(shè)置油密封擋圈，密封副之間無(wú)可見(jiàn)間隙，泄漏率小。蝶板與閥體間的膨脹間隙大，能有效防止因熱漲冷縮造成的卡死現(xiàn)象。本閥可配備多種驅(qū)動(dòng)裝置，如手動(dòng)裝置、蝸輪傳動(dòng)裝置、氣動(dòng)裝置、電動(dòng)裝置。通風(fēng)蝶閥廣泛用于治金、師化、電力、建材、礦山等工業(yè)管線，對(duì)介質(zhì)氣體氣控制或調(diào)節(jié)作用。
