Installation structure convenient for disassembling and assembling expansion joint of heat transfer casing

Abstract

The invention discloses an installation structure convenient for disassembling and assembling an expansion joint of a heat transfer casing. The installation structure comprises an expansion joint inner pipe, an expansion joint middle pipe and an expansion joint outer pipe which are arranged in sequence from inside to outside, wherein the expansion joint inner pipe is connected with an inner pipe of the heat transfer casing through an inner ring flange; the expansion joint middle pipe is connected with a middle pipe of the heat transfer casing through a middle ring flange; the expansion joint outer pipe is connected with an outer pipe of the heat transfer casing through an outer ring flange; two parts of the expansion joint middle pipe are connected with each other through a middle pipe connecting flange; and two parts of the expansion joint outer pipe are connected with each other through an outer pipe connecting flange. Due to the adoption of the installation structure, the problem of difficulty in installing and detaching an expansion joint of a novel heat transfer pipeline system is solved; meanwhile, when the expansion joint is damaged, convenience is brought to maintenance and replacement of the expansion joint, and losses caused by untimely maintenance and replacement are reduced; and the practicability of a heat transfer casing system is enhanced, and further development and application of the heat transfer casing system are propelled.

Description

technical field [0001] The invention relates to a heat transfer sleeve structure connected with a pipeline system, in particular to an installation structure for facilitating the disassembly and assembly of the expansion joint of the heat transfer sleeve. Background technique [0002] Chinese patent ZL201110102653.7, titled: A new type of high-efficiency energy-saving heat transmission three-layer pipeline system, the high-efficiency energy-saving heat transmission pipeline system can effectively reduce the heat loss of the pipeline for transporting hot fluid and transfer this part of heat loss to the return flow of cold fluid. Back, the heat dissipation loss is greatly reduced, and the system has a compact structure, a relatively simple process, and high reliability. As a compensation flexible structure, the expansion joint is connected with a new type of high-efficiency energy-saving heat transfer three-layer pipeline by traditional welding, and there are many deficiencies...
