Description

Technical Field

[0001] The utility model relates to the field of corrugated pipes, in particular to a polyethylene spiral mesh steel corrugated pipe. Background Art

[0002] A corrugated pipe is a tubular product with transverse corrugations, typically made of metal, plastic, or other materials. Its main characteristics are its elasticity and flexibility, which make it widely used in various fields.

[0003] According to the Chinese authorized patent announcement number: CN209540225U, a polyethylene reinforced spiral corrugated pipe is disclosed, which relates to the field of polyethylene pipe preparation. It includes an outer polyethylene layer, a first resin layer, a steel mesh layer, a second resin layer, an elastic rubber layer, a third resin layer, and an inner polyethylene layer arranged in sequence from the outside to the inside; a cross-shaped fiber mesh distributed on the elastic rubber layer; an annular corrugated reinforcement body arranged on the outside of the outer polyethylene layer; and steel belt reinforcement ribs arranged inside the annular corrugated reinforcement body. At the front end of the polyethylene reinforced spiral corrugated pipe, the elastic rubber layer and the outer polyethylene layer are longer than the steel mesh layer and the inner polyethylene layer, the elastic rubber layer and the outer polyethylene layer are the same length, and the steel mesh layer and the inner polyethylene layer are the same length. At the rear end of the polyethylene reinforced spiral corrugated pipe, the above arrangement is reversed. The two polyethylene reinforced spiral corrugated pipes are connected by extending the composite layer at both ends and plugging them together, which is reliable and convenient. Setting up an elastic rubber layer and a cross-shaped fiber mesh can absorb the deformation of the pipe body caused by thermal expansion and contraction; however, the polyethylene corrugated pipe still has shortcomings. During the installation process of the polyethylene corrugated pipe, if the actual required pipe length does not match the standard length, it is often difficult to effectively adjust the length, which leads to inconvenience in the installation process and increases the construction difficulty and time cost. Utility Model Content

[0013] Beneficial effects

[0014] The utility model provides a polyethylene spiral mesh steel corrugated pipe. Compared with the existing technology, it has the following advantages:

[0015] 1. In the present invention, by providing a telescopic adjustment mechanism, when the length of the pipe needs to be adjusted, the operator rotates the screw, and the screw and the hexagonal nut are engaged with each other to cause the flange adjustment plate to move axially relative to the flange connection plate. The movement of the flange adjustment plate drives the bellows layer structure to expand or contract, thereby increasing or decreasing the length of the pipe. The telescopic adjustment mechanism enables the pipe to be quickly and conveniently adjusted in length according to actual installation requirements, thereby improving the flexibility and adaptability of installation.

[0016] 2. In the present invention, through the arrangement of the corrugated pipe layer structure, the inner polyethylene layer provides a smooth inner surface to reduce fluid resistance, and the outer polyethylene layer protects the internal structure from the external environment. The spiral corrugations on its surface enhance the rigidity and pressure-bearing capacity of the pipe. The mesh steel wire reinforcement layer is spirally distributed between the buffer protection layer and the outer polyethylene layer, which greatly improves the strength and pressure resistance of the pipe. The buffer protection layer made of nitrile rubber effectively absorbs shock and vibration, making the corrugated pipe suitable for various complex conditions. BRIEF DESCRIPTION OF THE DRAWINGS
