Metallic reflection heat preservation cover and manufacturing method thereof

Abstract

Provided are a metallic reflection heat preservation cover and a manufacturing method of the metallic reflection heat preservation cover. The metallic reflection heat preservation cover mainly comprises a metallic shell and a built-in heat preservation layer. The metallic shell is a block-shaped shell formed by connecting four side wall plates, an outer wall plate and an inner wall plate. The outer wall plate and the inner wall plate are made into arc plates correspondingly and form the arc block-shaped shell together with the four side wall plates. The plate surface of the inner wall plate is coated with a high temperature resistant coating layer. The manufacturing method comprises the steps that firstly, materials are selected, then part cutting and blanking are carried out; secondly, an inner supporting frame is fixedly mounted through assembling and spot welding, and the side wall plates on the four edges and the outer wall plate are fixedly mounted on the inner supporting frame through assembling and spot welding; thirdly, multiple pieces of metallic foil are pressed respectively, arranged in the inner supporting frame and fixed; fourthly, the inner wall plate and the supporting frame are assembled and connected in a rived mode, and the block-shaped shell is formed; finally, the high temperature resistant coating layer is smeared on the plate surface of the inner wall plate. The metallic reflection heat preservation cover has the advantages of being low in manufacturing cost and environmentally friendly, generating no dust and the like, and manufacturing technology is easy.

Description

technical field [0001] The invention relates to a metal reflective heat preservation cover for covering and heat preservation of annular welds, valve bodies, flanges, valves, pipe fittings, branch pipe joints, etc., and a manufacturing method thereof, belonging to the technical field of heat preservation. Background technique [0002] The built-in insulation layer of the existing metal insulation cover is basically filled by glass wool and aluminum silicate fibers. However, in actual use, glass wool is not suitable for direct installation and use. If it is forced to be used directly, it will have a certain impact on the surrounding environment, and it is easy to cause skin itching or respiratory allergies; while choosing aluminum silicate fiber, there is a high cost. The compressive and flexural strength is relatively poor, it is easy to generate dust, and the waterproof performance is not very good. Contents of the invention [0003] The purpose of the present invention ...
