Abstract

The invention relates to the technical field of expansion joints, in particular to a corrugated expansion joint which comprises a protective pipe, an inner corrugated pipe, an anti-precipitation drainage mechanism and a water cooling protection mechanism. And the anti-precipitation drainage mechanism comprises a liquid inlet, a liquid outlet, an anti-precipitation tank and a flapping piece. The water cooling protection mechanism comprises a telescopic corrugated pipe, a second spring and a drainage pipe. And by arranging the anti-precipitation drainage mechanism, impurities in the liquid can be prevented from forming precipitation in the inner corrugated pipe, the flowing speed of the liquid in the inner corrugated pipe is increased, and the stability of the inner corrugated pipe during high-temperature liquid conveying is improved. And by arranging the water cooling protection mechanism, water cooling of the inner corrugated pipe is facilitated, and the stability of the inner corrugated pipe during high-temperature liquid conveying is improved. The inner corrugated pipe can be supported by arranging the supporting table, and the lower portion of the inner corrugated pipe is prevented from deforming when a large amount of high-temperature liquid is conveyed in the inner corrugated pipe.

Description

Technical field [0001] The present invention relates to the field of expansion joints, and in particular, a corrugated expansion festival. Background technique [0002] The corrugated expansion festival is a device having a telescopic function consisting of a metal bellows and a member capable of compensating the thermal deformation of the conduit, mechanical deformation, and absorption of various mechanical vibrations, and reducing the duct deformation and improving the service life of the pipeline service. [0003] Corrugation expansion energy saves a stretching effect. It is mainly realized by bellows. The structure of the bellows is particularly special, and there is a plurality of annular grooves in which the existing corrugated expansion festival is in the liquid, if the liquid contains some Impurities, these impurities can easily form precipitation in grooves in the bellows, and the corrugated expansion joints must be fixed at both ends at the time of mounting. If you want...
