摘　　要：根据液压胀接变形曲线及其胀接接头密封机理 ,分析槽边缘的接触正压力 。Based on the hydraulic expansion deformation curves and its seal mechanism of expannsion joints, the contact positive pressure at the groove edge was analyzed, the water tightness of the expansion joints of the grooved tube sheets, the relation between the water tightness and the expansion pressure, and the relation between the water tightness and the width of the groove, were determined.

关 键 词：液压胀接 开槽管板 密封压力
