Abstract

The utility model relates to a bent-tube insulation course fabricated member. The end face of the semi-circle right-angle bent-tube wall of the bent-tube insulation course fabricated member is divided into an internal layer and an external layer. The external end face is arranged on the same plane. The internal end surface takes the right-angle bisector of the fabricated member as the demarcation. The side corresponding to the external end face is concave inward, and the other side is convex outward. The concave size equals to the convex size. The internal end faces on both sides of the central line are in convex-concave staggered arrangement. The inner wall of the fabricated member is provided with a semi-circular groove. The utility model has the advantages of convenient construction and favorable thermal insulation effect.

Description

Bend pipe thermal insulation layer preform

The utility model relates to the thermal insulating material goods of a kind of heat distribution pipe network and central air-conditioner pipeline.

Handle at present and generally be: will cut into by the semicircle straight tube that thermal insulating material is made if be fan-shaped segmentation in the piece cross section for the insulation of heat distribution pipe network and central air-conditioner elbow of pipeline part, the order adjacent with little arc with the big little arc of arc by big arc is placed in outside the metal winding pipe, promptly forms and the corresponding thermal insulating material right-angle elbow pipe of metal winding pipe.And the insulation of flange part can only be wrapped up with the rock wool band.It is poor that material, constructional difficulties but also heat insulation effect are not only taken a lot of work, taken in above-mentioned insulation processing to elbow and flange, goes back befouling environment simultaneously.

The purpose of this utility model is to provide a kind of elbow thermal insulation layer preform that environment is not polluted the easy construction high insulating effect.

The purpose of this utility model can realize by following measure: a kind of bend pipe thermal insulation layer preform, it is characterized in that: the tube wall end face that semicircle right-angle elbow pipe two arc length do not wait divides inside and outside two-layer, outer end face is all on same plane, the internal layer end face serves as that boundary forms recessed end face with respect to outer end face one side indent with the right angle bisector of this preform then, the opposite side evagination forms boss, and the size of indent and evagination equates, the center line both sides are big simultaneously, small arc tube wall internal layer end face convex-concave is staggered, is provided with and bend pipe and the corresponding semi-circular groove of straight tube junction point protruding part at bend pipe thermal insulation layer preform inwall in addition.The opening part of cast-iron bend thermal insulation layer preform outer wall has tapering.

The utility model includes bend pipe thermal insulation layer preform.

Bend pipe thermal insulation layer preform is the semicircle right-angle elbow pipe of being made by rock wool or glass wool.The tube wall end face that these preform two arc length do not wait is divided equally inside and outside two-layer, and outer end face is on same plane, and the outer end face of large and small arc tube wall is all being crossed on the tangent plane of center line when two preform butt joints; The internal layer end face serves as that boundary forms a recessed end face with respect to outer end face one side indent with the right angle bisector of this preform then, the opposite side evagination forms a boss, and the size of indent and evagination equates that center line both sides large and small arc tube wall internal layer end face convex-concave is staggered simultaneously.As long as get the preform butt joint of two same specifications during construction, protruding, the recessed combination of its inner layer tube wall can coat whole elbow, is surrounded by moisture barrier materials such as tin foil paper or stainless steel in this preform outside then and gets final product.Be provided with and elbow and the corresponding semi-circular groove of straight tube junction point protruding part at above-mentioned preform inwall in addition,, increase heat insulation effect so that preform and metal pipe element are properer.

The utility model has following advantage compared to existing technology: easy construction, efficient height, high insulating effect, do not have environmental pollution, save manpower and fund, beautiful shape.

Drawing is described as follows:

Fig. 1 is the utility model steel elbow thermal insulation layer preform schematic perspective view.

Fig. 2 is that the utility model cast-iron bend thermal insulation layer preform master looks schematic representation.

The utility model is described in further detail to utilize the example shown in the accompanying drawing.In the utility model steel elbow thermal insulation layer preform schematic perspective view shown in Figure 1, this preform 1 is the semicircle right-angle elbow pipe of being made by rock wool, the tube wall end face that its two arc length does not wait divides inside and outside two-layer, outer end face 2 is on same plane, the internal layer end face serves as that boundary forms recessed end face 3 with respect to outer end face one side indent with the right angle bisector of this preform then, the opposite side evagination forms boss 4, and the size of indent and evagination equates that center line both sides large and small arc tube wall internal layer end face convex-concave is staggered simultaneously.Be provided with semi-circular groove 5 at bend pipe thermal insulation layer preform inwall in addition.In the utility model cast-iron bend thermal insulation layer preform schematic perspective view shown in Figure 2, its structure and steel elbow thermal insulation layer preform are basic identical, and just the opening part of outer wall has certain taper.
