The invention relates to the technical field of pipelines, and discloses a movable joint maintenance device. The movable joint maintenance device comprises a base, a liquid tank arranged on the base, a first cylinder barrel arranged on the base, a first piston which is slidably arranged in the first cylinder barrel and defines a first space with the bottom wall of the first cylinder barrel, a chuck arranged on the first piston and used for clamping pipe bodies, a liquid supply pipeline communicated with the first space and the liquid tank, a liquid return pipeline communicated with the first space and the liquid tank, a stop valve arranged on the liquid return pipeline, a first one-way valve which is arranged at an inlet in the liquid supply pipeline and allows liquid in the liquid tank to flow into the liquid supply pipeline, a second one-way valve which is arranged at an outlet of the liquid supply pipeline and allows the liquid in the liquid supply pipeline to flow into the liquid tank, and a driving mechanism used for driving the liquid to sequentially pass through the first one-way valve and the second one-way valve. According to the movable joint maintenance device, the two pipe bodies can be conveniently opened so that an O-shaped rubber ring in a movable joint can be replaced, and the air leakage condition of the movable joint can be fundamentally solved.

    本发明涉及管路技术领域,公开了一种活接头维护装置,包括座体、设于座体上的液箱、设于座体上的第一缸筒、滑设在第一缸筒内并与第一缸筒的底壁围合形成第一空间的第一活塞、设于第一活塞上并用于夹持管体的夹头、分别连通第一空间和液箱的供液管路、分别连通第一空间和液箱的回液管路、设于回液管路上的截止阀、设于供液管路内的入口处并允许液箱内的液体流入供液管路内的第一单向阀、设于供液管路的出口处并允许供液管路内的液体流向液箱内的第二单向阀,以及用于驱动液体依次经过第一单向阀和第二单向阀的驱动机构。本发明能够便捷地将两个管体撑开,以更换活接头内O型橡胶圈,能够从根本上解决活接头漏气的情况。
