Abstract
The utility model discloses a straight pipe structure with various diameters. The straight pipe structure is characterized by comprising a polyethylene internal layer pipe with an eccentric channel. A polyvinyl chloride middle layer pipe sleeves the polyethylene internal layer pipe. A latticed reinforcing rib is disposed between the polyethylene internal layer pipe and the polyvinyl chloride middle layer pipe. A polytetrafluoroethylene external layer pipe sleeves the polyvinyl chloride middle layer pipe. A steel wire mesh layer is disposed between the polyvinyl chloride middle layer pipe and the polytetrafluoroethylene external layer pipe. A rubber composite layer sleeves the polytetrafluoroethylene external layer pipe. A carbon fiber heating film layer sleeves the rubber composite layer. The straight pipe structure is reasonable in design, and provided with the three pipe layers, the latticed reinforcing rib and the steel wire mesh layer to increase the intensity of the pipe body and allow the pipe body to bear certain pressure and be not easily damaged. The rubber composite layer and the carbon fiber heating film layer are used for heat insulation to prevent the pipe body from freezing to fracture under low temperature.
Description
Technical field
The utility model relates to pipeline field, relates in particular to a kind of reducing straight tube structure.
Background technique
Existing reducing straight tube structure is simple, mostly adopts single layer structure, and its bearing capacity is limited, and particularly thin-walled end easily damages, and working life is low, and simultaneously in winter lower temperature in the situation that, its easy bursting by freezing, can not meet usage requirement.
Model utility content
The purpose of this utility model is the deficiency in order to make up prior art, and a kind of reducing straight tube structure is provided.
The utility model is achieved through the following technical solutions:
A kind of reducing straight tube structure, it is characterized in that: include the polyethylene inner layer pipe with eccentric channel, described polyethylene inner layer pipe is provided with PVC＝polyvinyl chloride middle tube outward, between described polyethylene inner layer pipe and PVC＝polyvinyl chloride middle tube, be provided with latticed stiffening rib, described PVC＝polyvinyl chloride middle tube is provided with teflon external pipe outward, between described PVC＝polyvinyl chloride middle tube and teflon external pipe, be provided with steel screen layer, described teflon external pipe is provided with rubber combined layer outward, the outer carbon fiber heating rete that is provided with of described rubber combined layer.
The utility model has the advantages that:
The utility model reasonable in design, by the structure of three layers of pipe structure and latticed stiffening rib and steel screen layer, increased the intensity of body, can bear certain pressure, be not easy to damage, by the structure of rubber combined layer and carbon fiber heating rete, can play insulation effect simultaneously, avoid body that bursting by freezing phenomenon occurs at a lower temperature.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Referring to accompanying drawing, a kind of reducing straight tube structure, include the polyethylene inner layer pipe 1 with eccentric channel, the outer PVC＝polyvinyl chloride middle tube 2 that is provided with of polyethylene inner layer pipe 1, between polyethylene inner layer pipe 1 and PVC＝polyvinyl chloride middle tube 2, be provided with latticed stiffening rib 3, the outer teflon external pipe 4 that is provided with of PVC＝polyvinyl chloride middle tube 2, between PVC＝polyvinyl chloride middle tube 2 and teflon external pipe 4, be provided with steel screen layer 5, outer rubber combined layer 6, the outer carbon fiber heating rete 7 that is provided with of rubber combined layer 6 of being provided with of teflon external pipe 4.
