Combined thermal insulation pipe shell

Abstract

Provided is a combined thermal insulation pipe shell. The combined thermal insulation pipe shell mainly comprises a straight pipe section thermal insulation pipe shell, an elbow pipe section thermal insulation pipe shell and a three-way pipe section thermal insulation pipe shell which can be mutually connected through pipes; the straight pipe section thermal insulation pipe shell is mainly composed of two semicircular pipe shell bodies with the same structures, the two connected end faces of the semicircular pipe shell bodies are provided with a convex end face and a concave end face which can be mutually matched respectively, and after the convex end face and the concave end face are mutually embedded, a complete straight pipe fitting is formed; the three-way pipe section thermal insulation pipe shell is mainly composed of two three-way pipe shell bodies which have the same structures and three pipe orifices of which the sections are each shaped like a semicircle, the two connected end faces of the three-way pipe shell bodies are provided with a convex end face and a concave end face which can be mutually matched respectively, and after the convex end face and the concave end face are mutually embedded, a complete three-way pipe fitting is formed; the elbow pipe section thermal insulation pipe shell is mainly composed of two elbow pipe shell bodies which have the same structures and semicircular sections, and the two connected end faces of the elbow pipe shell bodies are provided with a convex end face and a concave end face which can be mutually matched respectively.

Description

Technical field [0001] The invention relates to a combined heat-insulating pipe shell structure, in particular to a pipe fitting heat-insulating layer protection device suitable for convenient disassembly and assembly, and belongs to the technical field of heat preservation. Background technique [0002] At present, the application of heat preservation technology for fluid conveying pipe fittings is relatively common, and its purpose is to reduce the heat exchange between pipe fittings and the environment. The thermal insulation technology mainly adopts the combination of thermal insulation layer and protective layer. Specifically, it is a step-by-step construction method of thermal insulation layer and protective layer. First, the thermal insulation material (rock wool, glass fiber wool, etc.) is wrapped in the pipe body, including the elbow Sections, three-way pipe sections and multi-section straight pipes are fixed to form a thermal insulation layer, which is then bent and for...

AI Technical Summary

Problems solved by technology

The insulation structure is simple and widely used; however, the actual operation is difficult, especially because the whole pipe fitting body includes three-way pipe sections, elbow pipe sections and multiple straight pipe sections, so its material utilization rate is low, work efficiency is low, and the construction period is long
