Abstract
The utility model relates to a kind of metallic tape type insulation block, belongs to Nuclear piping and insulation of equipment technical field.This insulation block comprises the half-round tubular housing of inner filling multilayer stainless steel foil, the two ends of described housing have the outer panel and side inner panel that form the concavo-convex circular step of axle head respectively, and the involutory surface end plate of described housing and described outer panel and side inner panel have round spaced apart respectively.The utility model is easy to manufacture and assembling primarily of the half-round tubular housing that side plate and end face are formed, and the open-celled structure that end plate and side plate adopt, effectively inhibit heat bridge effect, properly settle the difficult problem that metallic tape type insulation block seam crossing temperature is too high.
Description
Technical field
The utility model relates to a kind of insulation block, and especially a kind of metallic tape type insulation block, belongs to Nuclear piping and insulation of equipment technical field.
Background technique
Along with the development of world nuclear power technology, need in containment building to take solid safety heat-preserving measure.
Retrieval find, application number be 96117250.9 and 201120138003.3 Chinese patent application individually disclose the metallic insulation of a kind of nuclear reactor pressure container and pipeline and a kind of incubation chamber of carrying out the assembled thermal insulation layer of outer wall for pipeline or equipment.Though, all there is the problem that seam crossing temperature is too high in each tool advantage of these products.
In addition, application number be 201320017233.3 Chinese patent application disclose a kind of Nuclear Power Plant Equipment and pipeline metallic tape type thermal insulation layer, still fail to solve very well the cooling problem of insulation block seam crossing.
Summary of the invention
The purpose of this utility model is: the shortcoming existed for above-mentioned prior art, proposes a kind ofly to have properly settled the too high problem of seam crossing temperature and the good metallic tape type insulation block of anufacturability.
In order to achieve the above object, the basic technical scheme of metallic tape type insulation block of the present utility model is: the half-round tubular housing comprising inner filling multilayer stainless steel foil, the two ends of described housing have the outer panel and side inner panel that form the concavo-convex circular step of axle head respectively, and the involutory surface end plate of described housing and described outer panel and side inner panel have round spaced apart respectively.
The utility model is easy to manufacture and assembling primarily of the half-round tubular housing that side plate and end face are formed, and the open-celled structure that end plate and side plate adopt, effectively inhibit heat bridge effect, properly settle the difficult problem that metallic tape type insulation block seam crossing temperature is too high.
It is that described stainless steel foil is formed by bending to semicircular paillon foil, described paillon foil is intervally distributed with hemisphere concaveconvex structure that the utility model further improves, and is therefore not only incubated, reflecting effect is good, and be convenient to automatic production.
Further, described housing is primarily of forming the outer panels of cylindrical and internal circular surfaces and wainscot, the outer panel of formation two axial ends and side inner panel respectively, and the end plate forming involutory surface is composed of a fixed connection.Especially, the middle panel transition by semicircle strip between described outer panel and side inner panel connects.Therefore, anufacturability is good.
Also further, described end plate has the uniform round of axially spaced-apart, and described outer panel and side inner panel have circumference round uniformly at intervals respectively.Especially, the round aperture of described outer panel is greater than the round aperture of side inner panel.The better effects if of such suppression seam crossing temperature rise.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the structural representation of the utility model embodiment's assembled state.In figure: 1. spring, 2. handle, 3. outer panel, 4. outer panels, 5. wainscot, 6. hasp, 7. end plate, panel 8., 9. side inner panel.
Fig. 2 is the insulation block perspective view after Fig. 1 embodiment decomposes.
Embodiment
The metallic tape type insulation block of the present embodiment as shown in Figure 1 (see Fig. 2), comprise the half-round tubular housing of inner filling multilayer stainless steel foil (not shown), stainless steel foil is formed by bending to semicircular paillon foil, paillon foil is intervally distributed with hemisphere concaveconvex structure.
Housing, primarily of the outer panels 4 and the wainscot 5 that form cylindrical and internal circular surfaces respectively, forms outer panel 3, the side inner panel 9 of two axial ends, and the end plate 7 forming involutory surface consists of resistance spot welding and riveted joint, and good manufacturability is easily manufactured.Connected by middle panel 8 transition of semicircle strip between the outer panel 4 at the axial two ends of housing and side inner panel 3, form the recessed circular step of the axle head matched and convex ring shape step respectively, so that axially docking.
The end plate 7 of housing involutory surface has the uniform round of axially spaced-apart, and outer panel 3 and side inner panel 9 have circumference round uniformly at intervals respectively.The round aperture of outer panel 3 is greater than the round aperture of side inner panel 9.
Experiment shows, because side plate and end plate all adopt open-celled structure, therefore effectively reduces heat bridge effect, successfully solve the difficult problem that metallic tape type insulation block radial and axial seam crossing temperature is too high, and plane end plate is convenient to making and installation.
Be summed up, the utility model compared with prior art, has following advantage and good effect:
1. end plate adopts open-celled structure to significantly reduce end plate seam crossing temperature.
2. side plate adopts open-celled structure to significantly reduce insulation block axis and other insulation block seam crossing temperature.
3. planar end plate manufacture is simple, easy for installation.
The hemisphere concavo-convex stainless steel foil insulation reflecting effect of filling is good, is convenient to automatic production.
