Detailed Description
The present invention is further described in detail below with reference to specific embodiments so that those skilled in the art can more clearly understand the present invention.
As shown in fig. 1-3, the HDPE double-wall corrugated pipe connecting device of the present invention comprises a connecting part 1 and a flow guiding part 2; the pair of flow guide parts 2 are respectively connected and arranged at two ends of the connecting part 1; the flow guide part 2 is embedded in the pipe 9 to be connected; a reinforcing ring 3 is embedded in the connection part of the inner surfaces of the connecting part 1 and the flow guide part 2 in a flush manner.
The joining portion 1 and the flow guide portion 2 are both cylindrical structures.
Fig. 1 shows a complete HDPE double-wall corrugated pipe connection, and since the connection is symmetrical at both ends, fig. 2 and 3 are labeled with a half structure; the pipe 9 to be connected is embedded into the flow guide part 2 so as to form a compact fit area with the inner wall of the pipe, thereby ensuring enough leakage resistance; the reinforcing ring 3 has the function of performing structural reinforcement at the port position of the double-arm corrugated pipe where the stress of the connecting device is most easily concentrated, and the reinforcing ring 3 can specifically adopt a steel ring-shaped piece to improve the integral ring rigidity of the connecting device; the surface of the reinforcing ring 3 is coated with a protective coating, so that the surface of the material can be protected, and the pollution of metal materials such as steel to raw materials conveyed in the double-arm corrugated pipe is avoided.
The outer surface of the connecting part 1 and the outer edge surface of the flow guide part 2 are transited through a bearing shoulder part 4; the bearing shoulder part 4 is jointed with the end surface of the pipe to be connected.
The bearing shoulder part 4 forms stable fit by utilizing the flat section area of the pipe 9 to be connected, thereby assisting the embedding depth of the flow guide part 2 to be limited on one hand, and also keeping the outer surface height of the connecting part 1 and the two ends of the pipe 9 to be connected flat, and the carrying and the installation are more convenient.
The embedded end of the flow guide part 2 is provided with a flow gathering inclined plane 21; the flow gathering inclined plane 21 is connected between the inner wall of the flow guide part 2 and the inner wall of the pipe to be connected.
Because the velocity of flow of the centre department is greater than the velocity of flow at the edge in the pipeline, so in order to promote the flow and the mixture of edge material, adopt and gather a class inclined plane 21 and reduce transfer passage's cross-section, and then let near the raw materials of double-arm bellows inner wall gather together and remix to the centre department, can promote the homogeneity of raw materials, reduce bottom raw materials and subside scheduling problem.
The middle section area of the flow gathering inclined plane 21 is provided with a flow disturbing block 22 in a raised mode.
As shown in fig. 2, the spoiler 22 can accelerate the contraction speed of the channel section in a unit distance, and the raised area can significantly block fluid gathered to the center, so that local turbulence occurs to promote the uniform mixing process of the raw material near the inner wall.
An annular groove 23 is arranged on the outer surface of the flow guide part 2; the annular groove 23 is filled with an adhesive.
Because the ring rigidity between the flow guide part 2 and the double-arm corrugated pipe is different, the sealing performance at the interface cannot be ensured only by nesting fit; the annular groove 23 can form a circle of compact closed structure on the joint interface, so that the anti-leakage capacity is obviously improved; the adhesive can be applied to the groove when not solidified, and the adhesive is allowed to stand after the nesting is completed to dry and complete the connection. The adhesive can be HY-302AB or HY-T160 glue.
The annular grooves 23 are provided in number at intervals along the length direction of the guide part 2.
The plurality of annular grooves 23 can form a plurality of sealing structures on the combination interface, so that the anti-leakage performance of the connecting device is further improved, and the connecting device is suitable for extreme use environments such as high pressure, vibration and the like.
The flow guide part 2 is provided with a material injection hole 24; one end of the material injection hole 24 is communicated with the inner cavity of the flow guide part 2, and the other end is communicated with the annular groove 23.
The injection hole 24 allows the step of adding the adhesive to be performed after the flow guide 2 and the HDPE double-arm corrugated pipe are inserted, and the adhesive is injected into the annular groove 23 from the injection hole 24. In actual processing, a pair of material injection holes 24 opposite to each other can be processed, one end of the material injection holes is used for feeding materials while the other end of the material injection holes is used for sucking when the adhesive is added, so that the adhesive is promoted to fill the whole annular groove 23 quickly, and the construction efficiency is improved.
A limiting ring 11 is arranged on the outer surface of the connecting part 1; a protective shell 5 is sleeved on the outer side of the connecting part 1; the inner wall of the protective shell 5 is provided with a limiting groove 51; the limiting groove 51 is embedded and meshed with the limiting ring 11; the two ends of the protective shell 5 extend and attach to the surface of the pipe to be connected.
