用于修理和升级管的设备
摘要：
用于暂时阻断通过管(20)的流体流动的设备，其包括：壳体(40)，其被配置成包围要阻断的流体流动所通过的管的一部分，所述壳体包括：第一部件，其限定被配置成接收所述管的所述部分的壳体室；以及第二部件，其从所述第一部件延伸，所述第二部件限定与所述壳体室相邻的装载空间；流动阻断装置(400)，其可沿插入轴线从在所述装载空间(410)中的装载位置通过在所述管的一侧中形成的孔移动至所述壳体室中的安装位置；且其中所述流动阻断装置(400)包括外密封部件(420)，当所述流动阻断装置(400)在所述安装位置中时，所述外密封部件(420)可在允许所述流动阻断装置(400)通过所述孔并允许通过在所述流动阻断装置(400)的外侧表面和所述管的部分的内表面之间的所述壳体室中的所述管的部分的流体流动的未扩张形态和被配置成通过基本上防止流体在所述流动阻断装置的外侧表面和所述管的部分的内表面之间通行来阻断通过所述管的部分的流体流动的扩张形态之间进行配置。
摘要（英）：

Apparatus for temporarily blocking fluid flow through a pipe (20), comprising: a housing (40) configured to enclose a portion of a pipe through which fluid flow is to be blocked, the housing comprising: a first part defining a housing chamber configured to receive the portion of the pipe; and a second part extending from the first part, the second part defining a stowage space adjacent the housingchamber; a flow blockage device (400) movable along an insertion axis from a stowed position in the stowage space (410) through an aperture formed in one side of the pipe to an installed position inthe housing chamber; and wherein the flow blockage device (400) includes an outer sealing part (420), the outer sealing part (420) being configurable when the flow blockage device (400) is in the installed position between an unexpanded configuration allowing the flow blockage device (400) to pass through the aperture and allowing fluid flow through the portion of pipe in the housing chamber between outer side surfaces of the flow blockage device (400) and inner surfaces of the portion of pipe and an expanded configuration configured to block fluid flow through the portion of pipe in the housing chamber by substantially preventing passage of fluid between outer side surfaces of the flow blockage device and inner surfaces of the portion of pipe.
