本文提出了双法兰压圈的应力分析和有关公式的应用。在以往的设计标准中,只有单法兰压圈的应力分析和计算方法。本文所提出的公式经简化后即为迄今所采用的单法兰压圈的计算公式。本文还对法兰压圈的环向应力作了较详尽的分析;对双法兰压圈和单法兰压圈的使用范围也提出了意见。
This paper presents the stress analysis of the double flange compression ring and the application of the formula. In the past design standards, only single-flange pressure ring stress analysis and calculation methods. The formula presented in this paper is simplified to the single flange compression formula adopted so far. This paper also made a detailed analysis of the hoop stress of the flange pressure ring; also put forward the opinion on the use scope of double flange pressure ring and single flange pressure ring.
