Pipeline thermal insulation device

Abstract

A pipeline thermal insulation comprises a housing, wherein an aluminium silicate salt thermal insulation cotton layer is arranged in the housing, an aluminium silicate thermal insulation cotton layer is arranged in the aluminium silicate salt thermal insulation cotton layer, two ends of the aluminium silicate thermal insulation cotton layer are provided with glass cotton, an aluminium inner layer is arranged on the aluminium silicate thermal insulation cotton layer, and a folding strip is arranged in the aluminium inner layer and is fixed with the housing by bolts; the pipeline thermal insulation device has the characteristics of good thermal insulation effect and heat leakage prevention.

Description

technical field [0001] The utility model relates to a thermal insulation device, in particular to a pipeline thermal insulation device. Background technique [0002] Conventional insulation measures are generally adopted for existing valves and pipelines, that is, electric heat tracing is wound on the equipment first, then insulation materials such as rock wool are wrapped, and finally the outer layer is sealed with galvanized iron sheets. Valves and other equipment have to remove the external insulation during annual maintenance. The removal process is complicated, and it cannot be restored. It wastes manpower and material resources. If the seal of the conventional insulation is not tightly sealed, sand, dust and moisture will easily enter, which will have a negative impact on the equipment and directly affect the insulation effect. Production safety, electric heat tracing is wound on the equipment, and the connection between the equipment is often rubbed with metal objects...

AI Technical Summary

Problems solved by technology

[0003] At present, some valves or pipelines are equipped with two open and close boxes connected by buckles to heat preservation devices, and the inside of the box is provided with a cavity. The cavity is a waterproof layer, and the box body itself is an insulation layer made of insulation materials. The insulation effect of this insulation device is poor. The shell is made of iron, which is easy to rust and deform during transportation. , laborious and time consuming when cutting
