用于压力容器凸台的排放配件
摘要：
一种装置(28)，被配置为定位在压力容器(10)的凸台(16)与壳体(18)之间。凸台(16)包括穿过其的孔(26)，并且孔(26)具有纵向轴线(36)。装置(28)包括环形本体和气体可透过特征部(30)。环形本体包括配置为邻接凸台(16)的内表面(38)和配置为邻接壳体(18)的外表面(46)。环形本体具有相对于纵向轴线(36)相对的第一(42)和第二(44)端。气体可透过特征部(30)提供在内表面(38)上并且至少从第一端(42)延伸到第二端(44)。本公开还描述了一种压力容器(10)，包括壳体(18)和凸台(16)，以及定位在凸台(16)与壳体(18)之间的装置(28)。一种用于形成压力容器(10)的方法，包括将凸台(16)安装在心轴上，将环形配件(28)定位在凸台(16)的颈部(22)周围，形成衬里(20)，以及形成外部壳体(18)。
摘要（英）：

An apparatus is configured to be positioned between a boss and a shell of a pressure vessel. The boss includes a bore therethrough, and the bore has a longitudinal axis. The apparatus includes an annular body and a gas permeable feature. The annular body includes an inner surface configured to abut the boss and an outer surface configured to abut the shell. The annular body has opposite first and second ends relative to the longitudinal axis. The gas permeable feature is provided on the inner surface and extends at least from the first end to the second end. The disclosure also describes a pressure vessel including a shell, and boss, and an apparatus positioned between the boss and the shell. A method for forming a pressure vessel includes mounting a boss on a mandrel, positioning an annular fitting about a neck of the boss, forming a liner, and forming an outer shell.
