Abstract

A spherical adapting angle compensator relates to the technical field of structural designs of pipeline compensators, and is used for angle compensation of air bleeding pipelines. A first spherical joint and a second spherical joint are in shaft-driving connection through a rotating shaft, a triangular circular-arc-shaped connection structure is provided with a lap-joint flat plate, and a fixing hole of which the diameter is equal to that of the rotating shaft is formed in the lap-joint flat plate. A corrugated sleeve is arranged outside the junction of the first spherical joint and the second spherical joint, and a sealing sleeve is arranged outside the spherical junction of the corrugated sleeve, the first spherical joint and the second spherical joint, and is connected in an air-tight manner. The spherical adapting angle compensator provided by the invention is simple in structure and convenient to manufacture, realizes pipeline angle compensation by the arrangement of the spherical joints in the corrugated sleeve of the compensator, can satisfy not only displacement compensation in the pipe axis direction of a pipeline and in the normal direction of a pipe axis but also angle compensation on the premise of guaranteeing pipeline airtightness, is high in stability and is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of structural design of pipeline compensators, in particular to a spherical joint angle compensator. Background technique [0002] The compensator is also called the expansion joint or the expansion joint, and it is mainly used to compensate the thermal expansion and contraction of the pipeline caused by the temperature change. If the pipe is not completely free to expand or contract when the temperature changes, thermal stresses will develop in the pipe. This stress must be considered in the pipeline design, otherwise it may cause the rupture of the pipeline and affect the normal production. As an important part of pipeline engineering, compensators play an important role in ensuring the long-term normal operation of pipelines. In the prior art, the pipeline compensator can provide compensation for the axial displacement and the normal displacement of the pipe axis, but cannot provide angular compensation...
