氣動(dòng)偏心半球閥

 
氣動偏心半球閥
氣動偏心半球閥說(shuō)明:
氣動偏心(xīn)半球閥利用偏心(xīn)閥(fá)體,偏心球體和閥(fá)座(zuò),閥杆作(zuò)旋轉(zhuǎn)運動時在(zài)共同軌(guǐ)迹自動定心,關閉過程中越關越緊,完全達到良好的密封目的。閥門的(de)球體和閥座完全(quán)脫離,消除了密封(fēng)圈的磨損,克服了(le)傳統球體閥座與球體密封面始終(zhōng)磨損的問題,非金屬彈性材料被嵌入金(jīn)屬座中,閥座(zuò)金屬面(miàn)受到良好的保護。本産品特别(bié)适用于鋼鐵業(yè),鋁業,纖維,微小固(gù)體顆粒,紙漿,煤灰(huī),石油氣等(děng)介質。
