Abstract

This invention relates to a universal hinged corrugated compensator, comprising end pipes, a corrugated pipe, and a hinge plate. End pipe I and end pipe II are respectively located at both ends of the corrugated pipe. An upright plate is provided on the outer surface of end pipe I, connecting to the hinge plate. The hinge plate is connected to a universal ring via a pin, and the universal ring is connected to end pipe II. An inner saddle plate is provided on the outer surface of end pipe I near the corrugated pipe, connecting and fixing the upright plate to the inner saddle plate. An outer saddle plate is provided on the outer surface of end pipe II, connecting and fixing the universal ring to the outer saddle plate and the upright plate via the hinge plate. Compared to existing technologies, this invention features a hinge mechanism on the outer surface of the end pipes on both sides of the corrugated pipe, connecting the two corrugated compensators with an intermediate pull pipe to form a combined expansion joint. This joint can absorb deflection or displacement in any direction of the pipeline, and the pin of the compensator can withstand internal pressure thrust. This invention has high strength, good sealing performance, and a long service life.

Description

Universal hinge corrugated compensator

technical field

The utility model relates to the technical field of pipeline compensators, in particular to a universal hinge type corrugated compensator.

Background technique

At present, pipelines used in petroleum, chemical, electric power and other industries generally need to install compensation devices. Existing pipeline compensation devices usually include rotary compensators, bellows compensators and spherical compensators, all of which are used to compensate the axial or to the displacement. Existing bellows compensators usually consist of bellows and end pipes. The end pipes are arranged at both ends of the bellows and connected with the bellows to form an integral structure. This type of corrugated compensator has a relatively small amount of compensation for the axial and radial displacement of the pipeline, and its strength is low. Due to the influence of the use environment, it is prone to failure or damage and leakage, and its sealing performance and service life are not ideal.

The purpose of this utility model is achieved by adopting the following technical solutions:

The universal hinged corrugated compensator includes end pipes, bellows and hinge plates, the two ends of the bellows are respectively provided with end pipes, the end pipes are connected by hinge plates, and the two ends of the bellows are respectively provided with end pipes I and the end pipe II, the outer surface of the end pipe I is provided with a vertical plate, the vertical plate is connected with the hinge plate, the hinge plate is connected with the universal ring through the pin shaft, and the universal ring is connected with the end pipe II.

As a preferred technical solution of the present utility model, an inner saddle plate is provided on the outer surface of the end pipe I close to the bellows, and the vertical plate is connected and fixed to the inner saddle plate.

As a preferred technical solution of the present invention, the outer surface of the end pipe II is provided with an outer saddle plate, and the universal ring is connected and fixed to the outer saddle plate and the vertical plate through a hinge plate.

As a preferred technical solution of the present invention, the outer surfaces of the end pipe I and the end pipe II are respectively provided with lifting lugs.

The beneficial effects of the utility model are: compared with the prior art, the utility model is provided with a hinge mechanism on the outer surface of the end tubes on both sides of the corrugated tube, and the two corrugated compensators are connected with an intermediate pull tube to form a combined expansion joint, which can To absorb the deflection or displacement in any direction of the pipeline, the pin shaft of the compensator can withstand the internal pressure thrust. The utility model has higher strength, better sealing performance and long service life.
