摘要
压力平衡型膨胀节能吸收管系或设备的热膨胀量,同时还可以平衡工作内压对支点产生的推力,因此被广泛地应用在透平及对推力有严格限制的设备进出口管道上。叙述了该类型膨胀节的结构特点、工作原理和推力计算方法。
The pressure-balanced expansionjoint can absorb the heat expansion rate from piping system or equipment and can balancethrust to the support point produced by the internal work pressure as well.Therefore it has widely been used for turbines and on the inlet and outlet pipes of equipment that has strict restrict to the thrust.The features of this kind expansion joint and its working principles and the calculation method of the thrust are narrated inthis article.
