Abstract: This specification discloses a barrier seal in which the pressure of the fluid being sealed is opposed by the flow rate of a buffer fluid with a movable ring interposed between the two. This ring is movable axially under the influence of the differential which obtains between the pressures of the sealing fluid and buffer fluid. Appropriate passages are provided for the buffer fluid and seals are provided between the movable ring and the shaft and housing in which the barrier seal is installed.

Abstract translation: 该说明书公开了一种阻挡密封件，其中流体的压力被密封，其中缓冲流体的流速与插入在两者之间的可移动环相反。 该环在受到密封流体和缓冲流体的压力之间的差速器的作用下轴向移动。 为缓冲流体提供适当的通道，并且密封件设置在可移动环与轴之间以及安装有隔离密封件的壳体之间。
