(K)Z43F、Z43H、Z43Y法蘭高壓平板閘閥采用新型平衡浮動密封結(jié)構(gòu),適用于壓力不大于60MPa,溫度不高于120℃的水、油、泥漿、天燃?xì)獾裙苈飞?,作為控制介質(zhì)的啟閉裝置。該產(chǎn)品結(jié)構(gòu)設(shè)計新穎,選材恰當(dāng),測試嚴(yán)格,操作輕便,具有較強(qiáng)防腐、耐磨、耐沖蝕性能,是石油工業(yè)一種理想的新型裝備。
Z43F/H法蘭高壓平板閘閥結(jié)構(gòu)特點及工作原理
采用浮動閥座,雙向啟閉,密封可靠,啟閉靈活。
閘板下部開有導(dǎo)流孔,并給予精密導(dǎo)向,同時,密封部均噴焊硬質(zhì)合金,耐沖蝕,故可用于節(jié)流。
閥體承載能力高,通道為直通式,全開時,與閘板導(dǎo)流孔相貫和直管相似,流阻力小。
閥桿密封采用復(fù)合填料,綜合聚四氟乙烯及丁腈橡膠各自的特點。使得密封可靠,磨擦力小。
關(guān)閉閥門時,順時針轉(zhuǎn)動手輪,閘板下移至底部,由于介質(zhì)的作用,將進(jìn)口端密封座推向閘板方向,形成較大的密封比壓,從而形成*道密封。同時,將閘板壓向出口端密封座上,成為雙重密封。
開啟閘板時,逆時針旋轉(zhuǎn)手輪,閘板上移,導(dǎo)流孔與通道孔相貫通。隨著閘板的上升,貫通孔逐浙加大,**,導(dǎo)流孔與通道孔相重合,此時全開,這樣實現(xiàn)了流量的任意調(diào)節(jié)。
