結(jié)構(gòu)特點(diǎn)及用途
本閥為敞開式設(shè)計(jì)結(jié)構(gòu),具有重量輕,易維護(hù)(密封膠圈更換、電動(dòng)裝置維護(hù)檢查、更換、閥門的局部維護(hù)均在外部,不影響閥門正常運(yùn)行),閥門的運(yùn)動(dòng)過程、開關(guān)狀態(tài)直觀性好,啟閉后檢查完成狀態(tài)極為方便,具有封閉式不可替代的優(yōu)勢(shì),缺點(diǎn)是啟閉時(shí)有少量的煤氣外漏。本閥門在設(shè)計(jì)上吸收了國(guó)外插板閥浮動(dòng)閥板先進(jìn)技術(shù);壓緊傳動(dòng)機(jī)構(gòu)采用齒圈、齒輪、梯形螺紋、絲桿副同步雙向壓緊。左、右旋梯形螺紋絲桿同步壓緊的優(yōu)點(diǎn)是;起動(dòng)力矩小,螺紋副自鎖性好,閥門密封可靠板移動(dòng)采用銷齒輪傳動(dòng)機(jī)構(gòu),不易積灰,滿足了粉塵多、潤(rùn)滑條件差、工作環(huán)境惡劣的場(chǎng)合使用。
本閥地面可配置防 爆型控制柜,實(shí)行現(xiàn)場(chǎng)控制和遠(yuǎn)距離與PLC系統(tǒng)連接控制,設(shè)計(jì)距離10米以上。
