Abstract

The utility model discloses a large-diameter polyethylene winding structure pressure pipe. The pipe is characterized by comprising the following layer structures: a polyethylene inner layer, an enhanced steel wire or glass fiber filament winding middle layer, and a polyethylene outer layer. The pipe bearing slot of the pipe utilizes fusion welding butted joint. The polyethylene outer layer is provided with at least one frame pipe. The frame pipe is provided with an arc material belt. Internal pressure resistance performance of the pipe reaches 10 MPa. Ring rigidity of the pipe is high. On-site construction is facilitated with efficiency and solidity.

Description

A kind of large footpath polyethylene spirally enwound structure pressure tube
Technical field
The utility model relates to a kind of large footpath polyethylene spirally enwound structure pressure tube.
Background technique
The market of major diameter pressure piping is very huge; water delivery engineering in China's various places construction, diversion works, row sea pipeline, irrigation conduit all need the large-diameter pipeline of a large amount of reliable, health, the protection of durable favorable environment again; but the traditional pressure piping adopting now; conventionally adopt maximum concrete duct and ductile iron pipeline, can not all meet a little these requirements.Facts have proved that according to the winding welding structure wall pipe of standard manufacture, being applied to buried drain pipe etc. is reliable without interior pressure field.Adopt and be wound around fusion molding manufacture major diameter plastic pressure pipe ground zero.Reason will be born higher stress at pressure tube tube wall, for the intensity of welding, has higher requirement, and major diameter plastic pressure pipe is applied to main conventionally, once consequence of failure is serious.
Summary of the invention
For solving above-mentioned existing shortcoming, main purpose of the present utility model is to provide a kind of large footpath polyethylene spirally enwound structure pressure tube of practicality, and the anti-interior performance of pressing reaches 10MPa, and product ring stiffness is high, and site operation is convenient, fast, firm.
For reaching above-described object, a kind of large footpath of the present utility model polyethylene spirally enwound structure pressure tube is taked following technological scheme:
A large footpath polyethylene spirally enwound structure pressure tube, is characterized in that, comprises with substructure, and internal layer is polyethylene, and middle level is wound around for strengthening steel wire or glass fiber yarn, and skin is polyethylene.
The band joint socket of described large footpath polyethylene spirally enwound structure pressure tube adopts melting welding docking.
The skeleton pipe of at least one is set on described outer layer polyethylene, on described skeleton pipe, arc material strip is set.
Adopt as above the utility model of technological scheme, there is following beneficial effect:
In anti-, press performance to reach 10MPa, product ring stiffness is high, and site operation is convenient, fast, firm.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to further illustrate the utility model, below in conjunction with accompanying drawing, further describe:
As shown in Figure 1, a kind of large footpath of the present utility model polyethylene spirally enwound structure pressure tube, comprises with substructure, and internal layer is the sealing of polyethylene 1 assurance fluid, and middle level is for strengthening steel wire or glass fiber yarn 2 windings, and outer is that polyethylene 3 is protective layer and coated skeleton pipe 4.The band joint socket of large footpath polyethylene spirally enwound structure pressure tube adopts melting welding docking.The skeleton pipe 4 that at least one is set on outer layer polyethylene 3, arranges arc material strip 5 on skeleton pipe 4.
A kind of large footpath of the present utility model polyethylene spirally enwound structure pressure tube, the anti-interior performance of pressing reaches 10MPa, and product ring stiffness is high, and site operation is convenient, fast, firm.
