RVHX弹性座封闸阀的外型尺寸连接规格多样，以DN（公称直径）和高度（Hmin和Hmax）为衡量标准。以下是不同DN尺寸对应的L（长度）和最小/最大高度值：
DN 50: L = 178mm, Hmin = 313mm, Hmax = 355mm
DN 65: L = 190mm, Hmin = 332mm, Hmax = 375mm
DN 80: L = 203mm, Hmin = 375mm, Hmax = 415mm
DN 100: L = 229mm, Hmin = 425mm, Hmax = 475mm
DN 125: L = 254mm, Hmin = 498mm, Hmax = 540mm
...以此类推到DN 600，对应的尺寸如下：
DN 600: L = 508mm, Hmin = 1220mm, Hmax = 1310mm
这些尺寸数据有助于在实际安装和选择RVHX弹性座封闸阀时，确保与管道系统兼容并满足阀门的开启和关闭要求。
