Modular heat preservation shell structure

Abstract

The invention provides a modular heat preservation shell structure. The modular heat preservation shell structure comprises a rigid heat preservation pipe shell (1) used for a flange, a valve and other parts needing to be dismounted frequently and a flexible heat preservation pipe shell (2) used for a straight pipe, a bent pipe, a three-way pipe and other pipelines. The rigid heat preservation pipe shell (1) comprises a first half shell body (11), a second half shell body (12), a fixing belt (14) and Z-shaped elastic liners (15); and the flexible heat preservation pipe shell (2) is composed ofa plurality of layers of single-layer flexible pipe shells (21) consistent in thickness, and each single-layer flexible pipe shell (21) comprises a third half shell body (211), a fourth half shell body (212), springs (214) and small fixing bosses (215). According to the modular heat preservation shell structure, by comprehensively applying the heat insulation principle and innovatively designingthe combined structure, the heat insulation pipe shell has the advantages of being good in heat insulation effect, small in occupied space, non-toxic, harmless, good in marine environment adaptability, convenient and fast to disassemble and the like.

Description

Technical field [0001] The invention relates to the technical field of thermal insulation engineering, in particular to a modular thermal insulation shell structure. Background technique [0002] Equipment under high-dose nuclear radiation environment or pipelines of nuclear power plants are subject to harsh environmental conditions such as high temperature, vibration, shock, high humidity, salt spray, and radioactivity. Therefore, the pipelines must be covered with heat-insulating shells. At present, the pipeline insulation layer in the nuclear irradiation environment mainly uses traditional thermal insulation materials such as ultra-fine glass wool. There are problems such as radioactive dust, collapse and accumulation, and uneven bulk density during installation and disassembly, which seriously affect the health of personnel and equipment. Or system performance. Summary of the invention [0003] In view of the above-mentioned problems in the prior art, the purpose of the prese...
