Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation pipe sleeves, in particular to a composite water-based ceramic particle thermal insulation pipe shell. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles. Usually, the fluid flows from the high pressure part of the pipeline to the low pressure part after being pressurized by a blower, compressor, pump and boiler. It can also be conveyed by the fluid's own pressure or gravity. When the pipeline needs thermal insulation protection, it needs to be protected by a pipe insulation sleeve.

The utility model relates to a detachable pipe insulation sleeve, including an insulation sleeve body, a protective pad fixedly connected to the inner wall of the insulation sleeve body, a plurality of evenly distributed protrusions fixed to the side of the protective pad away from the insulation sleeve body, and two symmetrically arranged Velcros fixedly connected to one side of the insulation sleeve body. The shortcomings of this technical solution are: 1. The insulation sleeve is susceptible to environmental erosion when in use, which reduces the service life of the insulation sleeve and is not conducive to replacement and recycling; 2. The Velcro connection method requires two layers of structure to overlap and stick together, and the long insulation sleeve is easy to loosen during adhesion, making the connection unstable; 3.
