Problems solved by technology
This device can also simplify the installation of the insulation layer in the process of pipeline disassembly and assembly, and is suitable for high-temperature or low-temperature pipelines, but its production and processing are relatively cumbersome. When the temperature in the pipe is greatly different from the ambient temperature, the thickness of the insulation cotton will cause a large volume; in addition , the insulation cotton is also easy to drop slag, which affects the clean room environment

Embodiment Construction
[0025] Such as figure 1 As shown, the main frame structure of this embodiment includes: a conventional heat-insulated high-temperature or low-temperature pipeline 1, a flange 2, a main body heat-insulating component 3, and an airgel blanket 4; figure 2 , image 3 It is a schematic diagram of the installation of the protective cover. In addition to the above components, it also includes: a protective cover 5 made of flexible multi-layer materials, a stainless steel throat clamp 6 and an airgel pressure ring 7 for quick installation.
[0026] The high-temperature or low-temperature pipeline 1 in this embodiment is a DN200 stainless steel pipeline, and the pipelines are connected by welding through flanges 2 . The main body insulation part 3 of the high-temperature or low-temperature pipeline is implemented according to actual needs. In a preferred embodiment, glass wool or airgel felt is used for conventional insulation, and the outer side is covered with aluminum skin; Airge...

The invention discloses a detachable type thermal insulation device for high-temperature or low-temperature pipelines. The detachable type thermal insulation device comprises a pair of flanges, a protective sleeve and a hooping component. The protective sleeve which is made of multi-layer flexible thermal insulation materials is coaxial with thermal insulation pipelines, circumferentially covered with a thermal insulation section and sleeved with the flanges and capable of freely retracting in an axial direction of the pipelines to do thermal insulation of a pipeline connecting position. Two ends of the protective sleeve are connected with common thermal insulation sections of the thermal insulation pipelines in an airtight sleeving manner through the rapid detachable banding component. The detachable type thermal insulation device is adaptable to connecting the pipelines with working temperature ranging from -100degrees to 135degrees, compact in structure, reusable, simple and convenient to detach and free of dropping residues or generating dust, and is particularly adaptable to applications with cleanliness requirement.
Description
technical field [0001] The invention relates to a thermal insulation device for high-temperature or low-temperature pipeline connection, in particular to a clean flexible thermal insulation interface structure for pipeline connection that can be quickly installed and repeatedly disassembled. Background technique [0002] In many industrial production or scientific experiment occasions, it is often necessary to insulate or insulate the high-temperature or low-temperature pipelines carrying the medium inside to prevent the outer surface of the pipeline from overheating or dew and frost. The conventional thermal insulation method for high-temperature or low-temperature pipelines is to wrap a certain thickness of polyurethane foam or glass wool and other thermal insulation materials around the outer circumference of the pipeline. Usually, these thermal insulation materials are formed at one time and fixed on the outside of the pipeline. [0003] However, quite a few applications...
