科恩科KNKE電動(dòng)高真空插板閥,electric high vacuum gate valve,是利用螺桿電動(dòng)推動(dòng),密封軸(桿)做軸向運(yùn)動(dòng),推(拉)動(dòng) 舉升機(jī)構(gòu),帶動(dòng)驅(qū)動(dòng)體沿軸向運(yùn)動(dòng),當(dāng)定位板運(yùn)動(dòng)到止動(dòng)塊時(shí),密封壓板和支撐板停止軸向 移動(dòng),而臥在密封壓板和支撐板球窩內(nèi)的鋼球被驅(qū)動(dòng)體推出球窩,從而使支撐板和密封壓板 背離驅(qū)動(dòng)體,而壓向閥門法蘭的支撐面和密封面,當(dāng)鋼球完全離開球窩而位于支撐板和密封 壓板的平面上時(shí),壓緊力達(dá)到最大,閥門被完全關(guān)閉,當(dāng)驅(qū)動(dòng)體被拉動(dòng)向后運(yùn)動(dòng)時(shí),由于密封 壓板和支撐板與法蘭面間摩擦力很大,鋼球被驅(qū)動(dòng)體拉回球窩,密封壓板和支撐板在中心彈 簧的作用下,壓向驅(qū)動(dòng)體,隨驅(qū)動(dòng)體一同向后運(yùn)動(dòng),離開法蘭孔口,使閥門完全打開。
電動(dòng)高真空插板閥適用的工作介質(zhì)為潔凈的空氣及非腐蝕性氣體。
electric ultra-high vacuum gate valve uses electric device to drive the stem, moving valve disc up and down to make the valve opened or closed. It is used to put through or cut off the airflow in vacuum pipeline. Applicable medium can be pure air and noncorrosive gases. With signal feedback device.
