重介系统管路中平板闸阀耐磨材料的选择

Selection of Wear Resistant Materials of Flat Gate Valve Used in Dense-medium System Pipeline

在煤炭系统中的重介质管路中,平板闸阀的磨损是比较严重的,磨损的部位主要是过流部件和密封材料,其中阀体的下部和闸板的下部边缘磨损最为严重,提高阀门的使用寿命,阀体和闸板的耐磨材料选择至关重要。

In the coal industry, the wears of fiat gate valve used in dense - medium system pipeline are very severe. Wear parts mainly are parts of water passing and seals, especially on the bottom of valve body and disc. To improve the valve using age, it is very important to select the wear resistant materials of fiat gate valve.
