Abstract
A metal insulating shell comprises at least two half insulating shells which join together. The two half insulating shells are semicircular box which is made of stainless steel; the inner of the box is provided a reflecting insulating element which is made of two pieces of stainless steel and the two semicircular box are intergraded together to form a circular insulating shell; the inner of the insulating shell is provided with a reflecting insulating element which is composed of at least three pieces of stainless steel which is corrugation, convexo concave or two-side shined; the external surface of the stainless steel sheet in the insulating shell is at least provided with two tooth strip or tooth ring which are in contact with the device or the pipe; at least two sides of the insulating shell are provided with agraffe; the external face of the stainless steel sheet of the insulating shell is provided with a fold grip. The utility model has the advantages of easiness in cleaning the surface and getting rid of dirt, great durability, convenience in installment and dismantlement and a great function of insulating, thereby, the utility model is suitable for insulating the heat device and pipe in variable circumstances.
Description
Technical field
The utility model relates to a kind of metal heat preservation shell, the especially heat power equipment of valve and pipeline and metal heat preservation shell of pipeline of being exclusively used in.
Background technique
In the prior art, it mainly is to be assembled with the thermal insulating material of homogeneity or the blanket formula thermal insulating material of the non-same sex, for example Chang Yong lightweight fiberglass, mineral cotton or porous thermal insulating material etc. in insulation shell that the structure of heat-preservating shell is formed.Insulation shell commonly used is then mainly made by glass fibre reinforced plastic material.These heat-preservating shells are many directly to make the two halves insulation shell, be exclusively used in the insulation of valvelet and pipeline, then adopt the insulation plate to be spliced the thermal insulation layer of installing on the frame as large turbo-type generator equipment mutually for relatively large heat power equipment and pipeline.But the heat-preservating shell of above-mentioned formation or layer have only adopted the big material of thermal resistance to carry out the obstruct of heat transfer, reduce pyroconductivity, the amplitude of its inside and outside temperature drop is very limited, it is extremely limited for the using effect of the pressure vessel and equipment of used in nuclear power station nuclear reactor plant and corresponding pipeline etc., reason just is that the temperature in these equipment and the pipeline is very high, adopt conventional thermal insulation layer technology can't reach heat preservation effect, what have can't use even at all.Must adopt good heat-insulation effect for pressure vessel and equipment that is similar to the used in nuclear power station nuclear reactor plant and corresponding pipeline, easy to use, simple in structure, the product of heat-preservating shell that cost is low or layer.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and a kind of metal heat preservation shell of reflection type thermal insulation structure is provided.
The purpose of this utility model is finished by following technical solution, it is joined by the two halves insulation shell at least and forms, each constitutes half round box by inside and outside stainless steel sheets described two halves insulation shell, in the reflection type insulation filler that is made of two stainless steel sheets is installed at least, and form a complete cylindrical shape insulation shell.
The superimposed reflection type insulation filler that constitutes of stainless steel reflection sheet that has ripple or concave-convex type, two-sided bright shape by three is installed in the described insulation shell at least.
At least be provided with two profile of tooth bar or profile of tooth circles with equipment or tube contacts on the interior stainless steel sheets outer surface of described insulation shell.
At least two corresponding sides of described insulation shell are respectively arranged with the male and female hasp that matches.
The outer stainless steel sheets outer surface of described insulation shell arc is provided with folding handle.
The utility model is owing to adopt stainless steel material, and the surface can not absorb and keep the sputter dirt of pollution, and surface clean is convenient, and decontamination is easy; Be applied on the heating power tankage and corresponding pipeline of used in nuclear power station nuclear reactor plant, make the obstruction of emergent reactor core cooling water system reduce to minimum; Serviceability is good, adopts stainless steel structure, makes it at steam, water, spray, irradiation, overheated, or under the environmental conditions of chemistry, do not break, it is big to bear pressure, be easy to installation and removal, good heat insulating can be applied to the characteristics such as insulation of heat power equipment and pipeline under the various environment.

Embodiment
The present invention will be described in detail below in conjunction with accompanying drawing: Fig. 1, shown in Figure 2, the utility model is joined by two halves insulation shell 1 at least and forms, described two halves insulation shell 1 respectively constitutes half round box by inside and outside stainless steel sheets 2, in the reflection type insulation filler 3 that is made of two stainless steel sheets is installed at least, and form a complete cylindrical shape insulation shell.
The superimposed reflection type insulation filler 3 that constitutes of stainless steel reflection sheet that has ripple or concave-convex type, two-sided bright shape by three is installed in the described semi-circular box body at least.These stainless steel reflection sheets are the sheet metal of mutual isolation, contour contour, can produce the reflection of closed air space and internal heat.Above-mentioned sheet metal is by the roll moulding, and the surface has lappet, after shearing, closely is arranged in the slim box body three layers of the thick placements of per inch; Sometimes can place one deck flat bed of no lappet, and, provide the convection current barrier in edge and box body spot welding in the centre.The inside and outside stainless steel sheets 2 of the semi-circular box body of described formation is made by the complete tinsel of a slice respectively, and axially the stainless steel sheets sealing is also used at two ends.Joint between two halves insulation shell 1 is respectively arranged with two pairs of male and female hasps 4 that match, and is convenient to install and remove the box maintenance.On every central exterior surface of two halves insulation shell 1, be provided with folding handle 5 in addition.The present invention simultaneously is for increasing heat insulating effect, and interior stainless steel sheets 4 inner surfaces of described two halves insulation shell 1 are provided with two profile of tooth bar 6 or profile of tooth circles with the radial arrangement of equipment or tube contacts.In other embodiments, at least two axial arranged profile of tooth bars 6 can be set also, make between the valve of insulation shell 1 and insulation or the pipeline to be formed with good air insulated space.
