双向密封刀闸阀(无凹槽刀型闸阀)内腔全衬根据不同工况可衬各种橡胶及四氟或者聚胺酯,提高阀门使用寿命,介质不与阀体直接接触,可耐强酸碱及各种化学物质Bi-directional sealed knife gate valve (non grooved slurry knife gate valve) has a fully lined inner chamber, which can be lined with various rubber, tetrafluoroethylene or polyurethane according to different working conditions, improving the service life of the valve. The medium does not come into direct contact with the valve body, and can withstand strong acids, alkalis, and various chemical substances
进口双向密封刀闸阀 无凹槽刀型闸阀性能描述 Performance description
无凹槽刀闸阀又称双向密封刀闸阀,铸铁阀体采用整体式结构刀闸阀, 包括阀体, 闸板和U 型密封条, 阀体左右两侧及中腔底部设有凹槽并装有弹性U 型密封条, 当阀门关闭时闸板下移, 闸板底部边缘与密封条接触进而压缩密封条进入凹槽中实现阀体和闸板的密封; 当刀闸阀开启时闸板上移, 闸板底部边缘与密封条脱离, 密封条弹起与凹槽平整, 能防止刀闸阀在使用过程中, 介质沉淀物积存在阀体中腔的凹槽里,不易堵塞、***,管道清洗方便,从而有效提高刀闸阀的密封效果, 防止阀门关闭时泄漏
