Description
Technical field
This utility model relates to pipe technology field, specifically provides a kind of two ends corrugated tube with Flange.
Background technology
The mode that existing corrugated tube uses when connecting is: directly docked the termination of two helical bellowses, after docking, Electric thermal smelting belt is wrapped up outside seam crossing, pass through Electric thermal smelting belt, two helical bellowses are integrally connected, this mode need to carry out sweat soldering, inefficiency at the construction field (site), and labor strength is big, additionally, if carrying out sweat soldering under the execution conditions of bad environments, welding quality is difficult to ensure that, sealing is poor, Seepage easily occurs, it addition, the crushing resistance of existing corrugated tube is poor, cause its service life short.
Therefore, how existing corrugated tube is carried out the improvement in structure, to improve its in-site installation efficiency, it is ensured that the sealing after installation, improve its crushing resistance simultaneously, become people's problem demanding prompt solution.
Summary of the invention
In consideration of it, the purpose of this utility model is the corrugated tube providing a kind of two ends with Flange, to solve the problems such as existing corrugated tube installation effectiveness is low, sealing is poor, crushing resistance is poor.
The technical scheme that this utility model provides is: a kind of two ends are with the corrugated tube of Flange, including body, body two ends are connected to the first adpting flange and the second adpting flange cooperated, it is provided with on first adpting flange towards outside annular groove, the O-ring seal coordinated with it it is provided with in annular groove, the periphery of annular groove is evenly distributed with connecting hole, the mating holes corresponding with connecting hole it is provided with on second adpting flange, body includes internal layer PE pipe and is socketed on outside internal layer PE pipe and corrugated outer layer PE pipe, the inwall of internal layer PE pipe axially arranged has interior reinforcement along it, at the wave trough position of outer layer PE pipe, ring-wound has external reinforcing ribs.
Preferably, it is provided with PE inserts in the cavity formed between internal layer PE pipe and outer layer PE pipe, in PE inserts, is uniformly laid with ring stiffener.
Further preferably, it is provided with corrugated steel band between internal layer PE pipe and outer layer PE pipe.
Further preferably, corrugated steel strip surface is compound in outer layer PE pipe and internal layer by adhering resin hot melt
Between PE pipe.
The two ends that this utility model provides are with the corrugated tube of Flange, its two ends arrange the first adpting flange and the second adpting flange that can cooperate, when needing to connect two corrugated tubes at the construction field (site), as long as the first adpting flange of a corrugated tube is connected with the bolt of mating holes by inserting connecting hole with the second adpting flange of another corrugated tube, when the first adpting flange and the second adpting flange dock, O-ring seal in annular groove closely cooperates with the second adpting flange, the sealing between corrugated tube can be realized, additionally, by axially arranged having interior reinforcement at the inwall of internal layer PE pipe along it, at the wave trough position of outer layer PE pipe, ring-wound has external reinforcing ribs, the crushing resistance of corrugated tube can be improved.
The two ends that this utility model provides are simple with the bellows structure of Flange, it is convenient to install, good airproof performance, crushing resistance are strong.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings and this utility model is described in further detail by embodiment:
Fig. 1 is the two ends sectional views with the corrugated tube of Flange.
Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is further explained, but does not limit to this utility model.
As shown in Figure 1, this utility model provides a kind of two ends corrugated tube with Flange, including body 1, body 1 two ends are connected to the first adpting flange 2 and the second adpting flange 3 cooperated, it is provided with on first adpting flange 2 towards outside annular groove 21, the O-ring seal (not shown) coordinated with it it is provided with in annular groove 21, the periphery of annular groove 21 is evenly distributed with connecting hole 22, the mating holes 31 corresponding with connecting hole 22 it is provided with on second adpting flange 3, body 1 includes internal layer PE pipe 11 and is socketed on outside internal layer PE pipe 11 and corrugated outer layer PE pipe 12, the inwall of internal layer PE pipe 11 axially arranged has interior reinforcement 13 along it, at the wave trough position of outer layer PE pipe 12, ring-wound has external reinforcing ribs 14.
These two ends are with the corrugated tube of Flange, its two ends arrange the first adpting flange and the second adpting flange that can cooperate, when needing to connect two corrugated tubes at the construction field (site), as long as the first adpting flange of a corrugated tube is connected with the bolt of mating holes by inserting connecting hole with the second adpting flange of another corrugated tube, when the first adpting flange and the second adpting flange dock, O-ring seal in annular groove closely cooperates with the second adpting flange, the sealing between corrugated tubing can be realized, additionally, by axially arranged having interior reinforcement at the inwall of internal layer PE pipe along it, at the wave trough position of outer layer PE pipe, ring-wound has external reinforcing ribs, the crushing resistance of corrugated tube can be improved.
In order to improve the crushing resistance of corrugated tube further, as the improvement of technical scheme, as it is shown in figure 1, be provided with PE inserts 15 in the cavity formed between internal layer PE pipe 11 and outer layer PE pipe 12, in PE inserts 15, uniformly it is laid with ring stiffener 16.
As the improvement of technical scheme, being provided with corrugated steel band (not shown) between internal layer PE pipe 11 and outer layer PE pipe 12, corrugated steel strip surface is compound in outer layer PE pipe 12 and internal layer by adhering resin hot melt
Between PE pipe 11.
Detailed description of the invention of the present utility model is to carry out writing according to the mode gone forward one by one, and highlights the difference of each embodiment, and its similar portion can be with cross-reference.
Above in conjunction with accompanying drawing, embodiment of the present utility model is elaborated, but this utility model is not limited to above-mentioned embodiment, in the ken that those of ordinary skill in the art are possessed, it is also possible on the premise of without departing from this utility model objective, various changes can be made.
