Description

Technical Field

[0001] This utility model belongs to the field of double-wall corrugated pipe technology, specifically, it relates to MPVE double-wall corrugated pipe. Background Technology

[0002] Double-wall corrugated pipes, as a new type of plastic pipe, are widely used in municipal drainage, sewage treatment, and farmland irrigation due to their light weight, corrosion resistance, and low drainage resistance. However, existing double-wall corrugated pipes still have many shortcomings in practical use: traditional corrugated pipes often use simple socket or flange connections, which are cumbersome to install, require professional tools, and have low connection efficiency; their sealing performance is poor, and under long-term use or geological subsidence, leakage problems easily occur at the joints, leading to sewage overflow, environmental pollution, and even affecting the normal operation of the pipeline system. Utility Model Content

[0003] To solve the above problems, the present invention adopts the following technical solution:

[0004] MPVE double-wall corrugated pipe includes: a plurality of corrugated pipes connected in sequence, each corrugated pipe including a corrugated portion, a first insertion portion and a second insertion portion, the first insertion portion and the second insertion portion being disposed opposite to each other at both ends of the corrugated portion; wherein, the corrugated pipe is connected to the second insertion portion of another corrugated pipe through the first insertion portion; the first insertion portion is provided with an annular groove, and the outer wall of the corrugated portion of the corrugated pipe is provided with corrugated protrusions.

[0005] Furthermore, the first insertion part includes a first tapered sleeve and a first cylindrical tube, one end of the corrugated part is connected to the first cylindrical tube through the first tapered sleeve, and the annular groove is disposed inside the first cylindrical tube.

[0006] Furthermore, the outer diameter of the first tube is larger than the outer diameter of the corrugated portion.

[0007] Furthermore, the diameter of one end of the first tapered sleeve is the same as the diameter of the corrugated part, and the diameter of the other end is the same as the diameter of the first cylindrical tube.

[0008] Furthermore, the second insertion part includes a second tube, on which an annular protrusion matching the annular groove is provided, and a sealing element is also provided at the annular protrusion inside the bellows.

[0009] Furthermore, the sealing element is a steel-framed rubber ring.

[0010] Furthermore, both the annular groove and the annular protrusion have triangular cross-sections.

[0011] The beneficial effects of this utility model are:

[0012] Convenient and efficient connection: By setting up a matching first and second connector, rapid connection between corrugated pipes is achieved. The annular groove of the first connector and the annular protrusion of the second connector form a precise fit, allowing installation to be completed without complicated tools, greatly improving construction efficiency and reducing labor costs.

[0013] Excellent sealing performance: A sealing element (such as a steel-reinforced rubber ring) is installed at the annular protrusion of the second connector, which, together with the triangular cross-section annular groove and annular protrusion, forms a multi-layer sealing structure. The steel-reinforced rubber ring combines elasticity and rigidity, effectively compensating for displacement caused by installation errors and geological settlement, significantly improving the sealing effect at the interface, avoiding leakage problems, and ensuring the environmental protection and safety of the pipeline system.
