Problems solved by technology

[0006] When connecting two spiral corrugated pipes, the inner wall of the joint of the corrugated pipes is pushed outward by the upper and lower working surfaces. If the extension is excessive, the joint is prone to open openings that expand outwards, so that even if it is bonded by a hot-melt tape At the opening, the joint of the corrugated pipe is also prone to cracks (the material of the hot-melt belt is worse than that of the corrugated pipe), and there is no connector to prevent the opening from appearing in the prior art

Embodiment Construction

[0022] The present invention will be described in further detail below by means of specific embodiments:

[0023] The reference signs in the drawings of the description include: collar 30, sleeve 20, ring block 22, flared end 21, rubber sealing ring 11, hot-melt belt B, bolt 32, nut 33, ear plate 31, ring body 12 .

[0024] Such as figure 1 and figure 2 As shown, the drainage pipe connector of this embodiment is used for connecting at the junction of two spiral corrugated pipes. As is well known to the public, the outer wall of the threaded corrugated pipe is provided with several sections of corrugation, and the corrugations include indentations and protrusions.

[0025] The drainage pipe connector in this embodiment includes a sleeve 20, and the inner wall of the sleeve 20 is provided with an annular block 22, and the two sides of the annular block 22 are respectively used for docking with the corrugated pipe, and one end of the sleeve 20 is a flaring end 21; if figur...

Abstract

The invention belongs to pipeline processing tools, and specifically relates to a connector for a draining pipeline. The connector for the draining pipeline comprises a sleeve of which the inner wall is provided with an annular block, wherein two sides of the annular block are correspondingly abutted with corrugated pipelines; one end of the sleeve is a port expansion end. The connector further comprises a sleeve ring, wherein two annular walls which extend toward the center of the sleeve ring are arranged on the sleeve ring; one annular wall is in shape fitting with the port expansion end, and the inner diameter of the other annular wall is equal to the diameter of a corrugation sunken part of the corresponding corrugated pipeline; the two annular walls are opposite in directions; the sleeve ring is positioned at the port expansion end which is positioned in an inner chamber that is encircled with the two annular walls. The connector can overcome the technical defect of easy opening in the prior art, and can limit a combining part of the pipeline from the outside of the pipeline so as to prevent opening from occurring.

Description

technical field [0001] The invention belongs to pipeline processing tools, in particular to drainage pipeline connectors. Background technique [0002] Large-diameter buried steel belt reinforced polyethylene (HDPE) spiral corrugated pipe is a new type of municipal drainage and sewage pipe. It uses the high elastic modulus of steel and adopts special production equipment to fold the steel belt into an inverted U shape. , and the inverted U-shaped steel strip is crimped into the curvature diameter of pipes of different specifications through the crimping machine. Bonded together to produce a steel belt reinforced polyethylene (HDPE) spiral corrugated pipe with smooth inner wall, inner and outer layers of polyethylene material, and steel belt in the middle layer, which not only retains the corrosion resistance, no scaling, and water resistance of polyethylene pipes. The resistance coefficient is small, the installation and connection are convenient, and the service life is lo...
