Disposable sleeve compensator

Abstract

The invention discloses a disposable sleeve compensator which comprises an outer sleeve connecting pipe, an outer sleeve barrel, an inner sleeve, a reinforcing plate, reinforcing box iron and annularseal rings. One end of the outer sleeve barrel is connected to the outer side of the end part of the outer sleeve connecting pipe in a sleeving manner while the other end of the outer sleeve barrel isconnected to the outer side of the end part of the inner sleeve in a sleeving manner; the reinforcing plate is correspondingly fixed out of a connecting position of the outer sleeve barrel and the inner sleeve; the reinforcing box iron is correspondingly fixed out of a connecting position of the outer sleeve barrel and the outer sleeve connecting pipe; two annular sealing grooves are formed in the outer side of the connecting end of the inner sleeve and the outer sleeve barrel; and the two seal rings are separately arranged in the sealing grooves. By arranging the O-shaped seal ring and the YX type seal ring, a double sealing effect is exerted. The reinforcing plate and the reinforcing box iron are mounted to increase the strength of a welded junction, so that the strength of the disposable sleeve compensator is higher and the sealing effect is better.

Description

technical field [0001] The present invention relates to the field of compensators, and more particularly to disposable sleeve compensators. Background technique [0002] The temperature, pressure and other parameters of the medium transmitted by the urban heating pipe network project vary greatly, and they are usually subject to large displacement changes due to the "expansion with heat and contraction with cold" during use. As we all know, the urban heating pipe network project uses a "compensator" to adjust thermal expansion and contraction to relieve the thermal stress inside the pipeline. During the construction process, the thermal expansion and contraction of the pipeline must be considered, otherwise the displacement of the pipeline will lead to cracking of the welding joint, causing leakage of the pipeline network, destroying the stability and continuity of the heating pipeline network operation, and even causing heat supply interruption, which will affect production...

AI Technical Summary

Problems solved by technology

Therefore, the stress on the compensator shell is relatively large, and the existing compensator cannot withstand the corresponding stress during use, and the problem of weld joint damage occurs from time to time, and the one-time compensator also has the problem of poor sealing effect.
