TECHNICAL FIELD

[0001] The utility model relates to PE pipe technical field, concretely relates to a high strength inner spiral PE pipe. BACKGROUND

[0002] PE pipe, full name polyethylene pipe, is a common plastic pipe. It is widely welcomed because of its excellent corrosion resistance, wear resistance, high temperature resistance and light installation mode, and its use field is wide. However, PE pipe has the following problems due to its own material reasons:

If the anti-bending ability is increased by increasing the pipe wall thickness, the weight of the pipe body will be greatly increased. INVENTION CONTENTS

BRIEF DESCRIPTION OF DRAWINGS

[0013] Figure 1 A structural diagram of a high-strength inner spiral PE pipe is provided. DETAILED DESCRIPTION

[0014] REFERENCE Figure 1 The utility model provides a kind of high-strength inner spiral PE pipe, including: pipe body 1, the inner wall of pipe body 1 is provided with inner spiral groove, the pipe wall of pipe body 1 includes inner wall layer 2 in its thickness direction in sequence, inner honeycomb layer 3 that is wrapped in the outer periphery of inner wall layer 2 and is honeycomb-shaped, and outer wall layer 4 that is wrapped in the outer periphery of inner honeycomb layer 3.When pipe body 1 is impacted by a hard object, inner honeycomb layer 3 can convert impact force into plastic deformation energy, so as to effectively absorb impact energy, so that the pipe wall is not easy to be penetrated, and honeycomb structure will not greatly increase the weight of PE pipe.

[0015] The holes in inner honeycomb layer 3 are radially arranged, so that the two ends of the holes in inner honeycomb layer 3 are respectively abutted against inner wall layer 2 and outer wall layer 4, thereby effectively increasing the vertical stiffness of the PE pipe, and having good deformation resistance in the length direction, so that the application range is wider.

[0016] In addition, the design of inner honeycomb layer 3 can have good sound insulation effect and reduce the noise generated by pipeline transportation.

[0017] In further embodiments, the inner side or the outer side of inner honeycomb layer 3 is further provided with a secondary honeycomb layer 5 in a honeycomb shape, and the holes in the secondary honeycomb layer 5 are arranged in an axial direction to further increase.

[0018] In addition, the outer wall layer 4 in the embodiment includes an inner layer 41, a wire mesh layer 42 wrapped around the outer periphery of the inner layer 41, and an outer layer 43 wrapped around the outer periphery of the wire mesh layer 42. When the PE pipe is pierced by a sharp object, the wire mesh layer 42 can effectively block the sharp object from advancing, thereby increasing the puncture resistance of the PE pipe.

[0019] Further, the surface of the wire mesh layer 42 has a reflective layer to help quickly determine whether the outer layer 43 is damaged and find the damaged position by using the reflective properties of the reflective layer.

[0020] In addition, since the existing PE material has no conductivity, it brings great inconvenience to the detection and positioning of the PE pipeline, therefore, the metal wire extending in the same direction with the pipe wall of the pipe body 1 is embedded in the pipe body 1, when it is embedded underground, the pipe body 1 can be detected and positioned through the metal wire.

[0021] In addition, in the embodiment, the side wall of one end of the pipe body 1 is provided with a pipe interface (not shown in the figure) tangentially communicating with the inner cavity, in some special application environment, the gas flow can enter the pipe tangentially through the pipe interface and rotate upward along the inner spiral groove, so as to form the central negative pressure and the relatively stable vortex flow state by the centrifugal force generated by the rotating smoke flow, so that the gas flow is stable and not easy to dissipate, and a higher lifting height can be achieved; at the same time, the centrifugal force and the central negative pressure generated by the rotating gas flow can make the water vapor in the gas flow be sucked and gathered in the pipe central column, so as to be isolated from the pipe wall, so that the pipe wall can be operated in a nearly dry state, which is helpful to prolong the service life.

[0022] As can be seen from the above, the inner wall of the pipe body 1 is provided with the inner wall layer 2, the honeycomb layer and the outer wall layer 4, which can effectively increase the mechanical strength of the PE pipe, so that the impact force can be converted into plastic deformation energy when the PE pipe is impacted by a hard object, so as to effectively absorb the impact energy, so that the pipe wall is not easy to be punched, and the weight of the PE pipe is not increased greatly. In addition, the design of the honeycomb layer can play a good sound insulation effect and reduce the noise generated by the pipeline transportation. In addition, the radially arranged honeycomb layer can effectively increase the vertical stiffness of the PE pipe.

[0023] The above is only the preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
