WO2013166154A1 EXTERNAL CLAMSHELL SLIP JOINT SEAL 审中-公开
外部CLAMSHELL滑动接头密封

EXTERNAL CLAMSHELL SLIP JOINT SEAL
Abstract:
The disclosure describes a slip joint seal (100) for a slip joint (100) that includes an outer pipe (102) and an inner pipe (104). The slip joint seal (100) includes a clamshell clamp (202) with an upper portion (206) and a lower portion (208) mateable to one another to form a hollow cylindrical ring (209). The ring has a base portion, a protruding portion, an inner surface (211), and an outer surface (111). A band (210) fits around the base portion for securing the upper and lower portions to one another around the slip joint (100). The slip joint seal (100) has a ceramic fiber filament (204) fiber with a first portion (214) that fits within the base portion and surrounds a portion of the slip joint (100) around a slidable interface (113). A second portion (216) fits within the protruding portion and fills an annular channel (114) of the slip joint (100). The clamshell clamp (202) and the filament (204) discourage leaking from the interface (113) between the inner pipe (104) while allowing relative movement between the inner pipe (104) and the outer pipe (102).
Abstract(Chinese):

本公开描述了一种用于滑动接头（100）的滑动接头密封件（100），其包括外管（102）和内管（104）。 滑动接头密封件（100）包括具有上部（206）和彼此配合以形成中空圆柱形环（209）的下部（208）的蛤壳式夹具（202）。 环具有基部，突出部，内表面（211）和外表面（111）。 带（210）围绕基部安装，用于将上部和下部彼此围绕滑动接头（100）固定。 滑动接头密封件（100）具有陶瓷纤维细丝（204），其具有第一部分（214），第一部分（214）装配在基部内并围绕可滑动界面（113）围绕滑动接头（100）的一部分。 第二部分（216）装配在突出部分内并填充滑动接头（100）的环形通道（114）。 蛤壳式夹具（202）和细丝（204）阻止从内管（104）之间的界面（113）泄漏，同时允许内管（104）和外管（102）之间的相对移动。
