Abstract
The utility model discloses an intermediate layer type plastic conduit that prevents frostbite, including PVC inner structure layer, middle filling layer, PVC outer structural layer, its characterized in that along alternative a plurality of PVC support columns and a plurality of the PVC archs of being provided with of PVC inner structure layer circumference on the middle filling layer, support column and a plurality of archs with a PVC inner structure layer body coupling, the support column with it has the rock wool to fill between the bellied clearance, the outer periphery of support column is provided with the recess, be provided with the PVC lug rather than the looks adaptation in the recess, the lug with a PVC outer structural layer body coupling. The utility model discloses firm in connection between layer and the layer be difficult for leading to the fact the dislocation between layer and the layer, and pipeline compressive capacity is strong, and is not fragile.
Description
Technical field
This utility model relates to plastic conduit, is specifically related to a kind of interlayer anti-freeze type plastic conduit.
Background technology
At present, Anti-freezing pipeline on market generally adopts double-skin duct, and between double-skin duct, it being filled with heat-preservation cotton, it connects not tight between layers, installs in handling process in transport, easily cause dislocation between layers, further, the heat-insulation layer loose owing to which increasing material, make the inside and outside two-layer duct thickness with supporting role reduce, thus reducing the anti-pressure ability of pipeline so that it is fragile.
Utility model content
The purpose of this utility model is in that to provide a kind of interlayer anti-freeze type plastic conduit, and it is connected firmly between layers, does not easily cause dislocation between layers, and pipeline anti-pressure ability is strong, is hardly damaged.
For achieving the above object, technical solution adopted in the utility model is:
A kind of interlayer anti-freeze type plastic conduit, including PVC inner structural layer, intermediate filling layer, PVC outer structural layer, in described intermediate filling layer, it is provided with some PVC support columns and some PVC projections, described support column and some protruding and described PVC inner structural layer one be connected along PVC inner structural layer circle alternate；Being filled with rock wool between the gap of described support column and described projection, the outer circumference surface of described support column is provided with groove, is provided with matched PVC projection in described groove, and described projection is connected with described PVC outer structural layer one.
Further, the cross section of described support column is trapezoidal, and the inner periphery of described support column is wider than the excircle of described support column；The cross section of described projection is triangle.
The beneficial effects of the utility model are: this utility model is provided with the support column and projection that are connected with inner structural layer one in intermediate filling layer, and it is provided with groove on the support columns, the projection being connected with outer structural layer one it is provided with in groove, thus, tube wall is reinforced so that be connected firmly between layers, do not easily cause dislocation between layers, and pipeline anti-pressure ability is strong, it is hardly damaged.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1, inner structural layer；2, intermediate filling layer；3, outer structural layer；4, support column；5, protruding；6, rock wool；7, groove；8, projection.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, by detailed description of the invention, this utility model is further described.
As shown in Figure 1, a kind of interlayer anti-freeze type plastic conduit, including PVC inner structural layer 1, intermediate filling layer 2, PVC outer structural layer 3, in described intermediate filling layer 2, it is provided with some PVC support columns 4 and some PVC projections 5, described support column 4 and some projections 5 be connected along PVC inner structural layer 1 circle alternate with described PVC inner structural layer 1 one；Being filled with rock wool 6 between described support column 4 and the described gap of protruding 5, the outer circumference surface of described support column 4 is provided with groove 7, is provided with matched PVC projection 8 in described groove 7, and described projection 8 is connected with described PVC outer structural layer 3 one；This utility model is provided with the support column 4 and protruding 5 being connected with inner structural layer 1 one in intermediate filling layer 2, and on support column 4, it is provided with groove 7, the projection 8 being connected with outer structural layer 3 one it is provided with in groove 7, thus, tube wall is reinforced so that be connected firmly between layers, do not easily cause dislocation between layers, and pipeline anti-pressure ability is strong, it is hardly damaged.Fill rock wool 6 between intermediate filling layer 2 support column 4 and the described gap of protruding 5, play the effect intercepting pipeline internal-external heat exchange, thus playing antifreeze or insulation effect；Described inner structural layer 1, outer structural layer 3, support column 4, projection 8 all adopt PVC material, in process of production, are conducive to each structure fusion to be integrally forming, make connection more firm.
Further, the cross section of described support column 4 is trapezoidal, and the inner periphery of described support column 4 is wider than the excircle of described support column 4；The described cross section of protruding 5 is triangle, not only makes the connection between inner structural layer 1 and intermediate filling layer 2 more firm, also facilitates of the present utility model manufacturing.
