Abstract

A high-temperature metal seal sleeve compensator comprises an outer sleeve, an inner sleeve and a pulling-out preventing flange, wherein a flange of the outer sleeve is connected with the pulling-out preventing flange through a bolt, the inner sleeve is inserted into the outer sleeve through an outer sleeve inserting hole in a front end cover of the outer sleeve, the outer wall of the inner sleeve is tightly matched with the outer sleeve inserting hole, the rear end of the inner sleeve is fixedly connected with a supporting ring, and the outer annular surface of the supporting ring is in sliding fit with the inner wall of the outer sleeve. The high-temperature metal seal sleeve compensator is reasonable in design and safe and reliable in work performance, service life is more than 20 years, and therefore a maintaining well which is specially arranged can be omitted, construction cost can be greatly lowered, and the high-temperature metal seal sleeve compensator can be used for conveying pipelines of city and town heating, metallurgy, electric generation, petrifaction, construction and other industries more conveniently.

Description

technical field [0001] The invention belongs to a pressure pipeline element and is mainly used for compensating the axial expansion and radial rotation of the pipeline. Background technique [0002] Due to the temperature difference change of the working medium and the installation error and other factors, the axial expansion and radial torsion of the pipeline are caused. In order to eliminate the axial expansion and radial torsion of the pipeline, a packing type compensator or a bellows compensator is usually installed in the pipeline. Since the packing type compensator needs to replenish the packing regularly, a special maintenance well needs to be set up in the underground pipeline, which increases the engineering cost and maintenance cost; Corrosion, resulting in bursting, prone to major accidents and large economic losses. Contents of the invention [0003] The purpose of the present invention is to provide a high temperature metal sealing sleeve compensator with saf...
