【摘要】：采用数值模拟方法研究了法兰结构参数对双楔角环垫密封接触压力及有效密封宽度的影响,并通过正交实验法对法兰结构参数进行了显著性分析.结果表明,随法兰各结构尺寸减小,双楔角环垫主、从密封面最大接触压力不同程度增大.法兰结构参数对新型双楔角环垫密封性能影响的显著性顺序为主法兰小端外径法兰外径锥颈大端厚度锥颈高度法兰有效厚度.主法兰小端外径对双楔角环垫主、从密封面最大接触压力影响最大.
[Abstract]:The influence of flange structure parameters on contact pressure and effective seal width of double wedge ring gasket is studied by numerical simulation method. The significance of flange structural parameters is analyzed by orthogonal experiment. With the flange structure size decreasing, double wedge angle ring pad main, The effect of flange structure parameters on the sealing performance of the new type of double wedge ring gasket is mainly in the order of effectiveness of flange flange with small end outer diameter flange outer diameter flange big end thickness cone neck height flange effective thickness of flange structure parameters influence on sealing performance of new type double wedge ring gasket with different degrees of maximum contact pressure. Main flange small end outer diameter double wedge angle ring pad main, The maximum contact pressure from the sealing surface has the greatest effect.
