A metal reflective insulation block

Abstract

The invention provides a metal reflection type heat insulation block and belongs to the technical field of nuclear power pipelines and devices. The heat insulation block comprises two combined half block bodies. Each half block body comprises an outer panel, an inner panel and a hole forming side plate, wherein two vertical opposite end faces of each outer panel are provided with semicircular main pipe gaps; each inner panel is provided with a semicircular main pipeline; the middle of each semicircular main pipeline is provided with a semicircular branch pipeline matched with a branch pipeline; each hole forming side plate is a semicircular ring, wherein the end face of the semicircular ring is provided with through holes distributed at intervals; the semicircular main pipe gaps and a semicircular branch pipe gap are provided with inward semicircular turned edges respectively; each semicircular turned edge is fixedly connected with the outer side of a semicircular strip-shaped middle plate; the inner side of each middle plate is fixedly connected with an outer circular turned edge of the corresponding hole forming side plate; a semicircular step-shaped linkage structure from each outer panel and the corresponding hole forming side plate is formed; and a space between each inner panel and the corresponding outer panel is filled with a metal foil reflection heat insulation layer. The metal reflection type heat insulation block is good in heat insulation effect and capable of meeting the requirements for heat insulation of three-way structural pieces in the nuclear electrical field, and the heat insulation function is played to the maximum degree.

Description

technical field [0001] The invention relates to a thermal insulation block, in particular to a metal reflective thermal insulation block with a three-way structure, which belongs to the technical field of nuclear power pipeline and equipment thermal insulation, and can be popularized and applied in thermal power, chemical industry, petroleum and other fields. Background technique [0002] Many pipelines and equipment in nuclear power plants operate under high temperature conditions. In order to reduce the heat loss of pipelines and equipment, ensure that the temperature and thermal stress of the concrete wall of nuclear power plants meet the design requirements, and improve the thermal economy of power plant operation, it is necessary to coat the outer walls of high-temperature pipelines and equipment with insulation layers. [0003] Due to the high radioactivity in nuclear power plants, non-metallic insulation materials used in general industrial pipelines and equipment are...
