Description

Technical Field

[0001] The utility model relates to the technical field of polyethylene pipes, in particular to a high-density polyethylene pipe. Background Art

[0002] Polyethylene pipe, also known as PE pipe, is a pipe made of polyethylene resin as the main raw material through an extrusion molding process. Polyethylene pipe has excellent low-temperature resistance, chemical stability and electrical insulation, and is widely used in indoor and outdoor water supply pipes, drainage pipes, gas pipelines and other fields.

[0003] The Chinese patent with authorization publication number CN213177259U discloses a high-density polyethylene outer protective pipe, which is provided with a thermal insulation layer, a first insulating layer, an electric heating layer, a second insulating layer, and a protective layer. The inner side of the outer protective pipe body is fixedly connected to the thermal insulation layer, the inner side of the thermal insulation layer is fixedly connected to the first insulating layer, and the inner side of the first insulating layer is fixedly connected to the electric heating layer. By providing the protective layer, it can effectively contact the pipeline evenly to prevent uneven contact with the outer wall of the pipeline, thereby causing deformation of the pipeline. By providing the electric heating layer, heat can be added to the inside of the outer protective pipe body to prevent the liquid in the pipeline from freezing and then clogging the pipeline in cold places. By providing the first insulating layer and the second insulating layer, the electric heating layer is prevented from conducting electricity when heating. By providing the thermal insulation layer, the heat inside the outer protective pipe body is prevented from dissipating to the outside through the outer protective pipe body.

[0004] Although the high-density polyethylene tube mentioned above is provided with a first insulating layer and a second insulating layer to prevent the electric heating layer from conducting electricity when heated, and the heat preservation layer is provided to prevent the heat inside the outer protective tube body from being dissipated to the outside through the outer protective tube body, generally, the high-density polyethylene tube is connected only by threads, and the stability after connection is low, resulting in poor sealing effect of the device. For this reason, we propose a high-density polyethylene tube. Utility Model Content

[0005] The purpose of the present invention is to provide a high-density polyethylene pipe to solve the problem raised in the above background technology that since general high-density polyethylene pipes are connected only by threads, the stability after connection is low, resulting in poor sealing effect of the device.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a high-density polyethylene pipe, comprising:

[0007] One end of the pipe body is connected to a positioning end head, and one end of the positioning end head is connected to a threaded joint. A pipe joint is installed between the pipe bodies, and a connecting end head is provided at the connection between the pipe joint and the threaded joint. An elastic rubber ring is installed inside the connecting end head.

[0008] A positioning rod is installed on both sides of the outer wall of the connecting end head, and a connection hole is opened inside both ends of the positioning end head. A positioning bolt is installed inside one end of the positioning rod;

[0009] The base material layer is arranged inside the pipe body, the inside of the base material layer is provided with polyethylene filler, and the outer wall of the base material layer is provided with reinforcing mesh ribs.

[0010] Preferably, the pipe body is fixedly connected to the positioning end head, the pipe joint is fixedly connected to the connecting end head, and the pipe body is connected to the pipe joint via a threaded joint.

[0011] Preferably, the positioning bolt passes through the interior of the positioning rod, and the positioning bolt is threadedly connected to the positioning end through a connecting hole.

[0012] Preferably, the pipeline body is further provided with:

[0013] Anti-wear bumps are arranged on the outer wall of the pipe body and are evenly distributed among the anti-wear bumps.

[0014] Preferably, the pipe joint is further provided with:

[0015] Anti-wear convex strips are arranged on the outer wall of the pipe joint, and the anti-wear convex strips are evenly distributed.

[0016] Preferably, the polyethylene filler is evenly distributed along the interior of the base material layer, and the reinforcing mesh is tightly fitted to the base material layer, and the reinforcing mesh is a hollow mesh structure.

[0017] Compared with the prior art, the present invention provides a high-density polyethylene pipe with the following beneficial effects:

[0018] The utility model can pass through the positioning rod and fix the positioning end head relatively to each other through the positioning bolt, thereby facilitating the reinforcement of the pipe body and the pipe joint to prevent them from falling off from each other, avoiding the problem that the general high-density polyethylene pipe is connected only by threads when being connected, resulting in low stability after connection and poor sealing effect of the device.
