摘要： A flange (50) for a pump (10) comprises a first face (65); a second faces (85); a passageway (110) for cryogenic fluid flow extending from the first face (65) to the second face (85), and the passageway (110) for a pipe (40) and comprising a first portion (120) of a first diameter and a second portion (130) of a second diameter greater than the first diameter, wherein when the pipe (40) has an outer diameter that is smaller than the second diameter, a gap (140) is formed between the pipe (40) and the passageway (110) where the pipe (40) passes through the second portion (130); and a first annular groove (155) in one of the first face (65) and the second face (85) and extending around the passageway (111), wherein the first annular groove (155) in cooperation with the passageway (111) forms a bellows. The gap (140) and bellows increase the thermal resistance between the passageway (111) and the flange (50), and the bellows allows for flexure during thermal contractions of the flange reducing thermal stress on welded fluid seals.

摘要： Draining a cryogenic storage vessel to remove a pump is timing consuming, expensive and can result in increased greenhouse gas emissions. A cryogenic storage vessel comprises an inner vessel defining a cryogen space and an outer vessel spaced apart from and surrounding the inner vessel, defining a thermally insulating space between the inner and outer vessels. A receptacle comprises an outer sleeve and an inner sleeve, and defines passages for delivery of liquefied gas from the cryogen space to outside the cryogenic storage vessel. The outer sleeve intersects opposite sides of the inner vessel, with the opposite ends of the outer sleeve defining an interior space in fluid communication with the thermally insulating space that is sealed from the cryogen space. The inner sleeve has an open end supported from the outer vessel, and extends into the interior space defined by the outer sleeve, and a closed end opposite the open end, defining a receptacle space that is fluidly isolated from the thermally insulating space. A fluid communication channel extends from the cryogen space to the receptacle space, and can be selectively closed to allow the pump to be removed.
摘要翻译：排出低温储存容器以除去泵是耗时时间的，昂贵的并且可能导致温室气体排放增加。低温储存容器包括限定冷冻剂空间的内部容器和与内部容器隔开并围绕内部容器的外部容器，在内部和外部容器之间形成隔热空间。容器包括外套筒和内套筒，并且限定用于将液化气体从冷冻剂空间输送到低温储存容器外部的通道。外套筒与内容器的相对侧相交，外套管的相对端限定与隔热空间流体连通的内部空间，其与冷冻剂空间密封。内套管具有从外容器支撑的开口端，并且延伸到由外套筒限定的内部空间中，并且与开口端相对的封闭端限定与隔热空间流体隔离的容纳空间。流体连通通道从冷冻剂空间延伸到容器空间，并且可以选择性地关闭以允许泵被移除。

摘要： A cryogenic storage vessel (10) having an inner vessel (20) defining a cryogen space (25); an outer vessel (30) spaced apart from and surrounding the inner vessel, defining a thermally insulating space (40) between the inner vessel and the outer vessel; and a receptacle (15) defining passages for delivery of liquefied gas from the cryogen space to outside the cryogenic storage vessel. The receptacle has an elongated outer sleeve (80) defining an interior space (85) in fluid communication with the thermally insulating space that is sealed from the cryogen space; an elongated inner sleeve (120) extending into the interior space defined by the elongated outer sleeve defining an inner receptacle space that is fluidly isolated from the thermally insulating space; and a collar (270) extending around an inner surface of the elongated inner sleeve (120) which seals against a cooperating surface of a pump assembly (300) when a pump assembly is installed in the cryogenic storage vessel (10) thereby dividing a warm end (330) from a cold end (340) of the receptacle.
