Abstract
The utility model relates to an extending device of tubes. The main technological characteristic is that the device comprises a tube of which two ends are equipped with conventional flanges, enabling the tube to be connected with other tubes in series. The middle of the tube is provided with a swollen corrugation which can effectively protect the tube from pressing or stretching and guarantee safety of the tube. The utility model is simple in structure, easy in laying and widely applicable for tube laying.
Description
The utility model relates to a kind of pipeline expansion device.
Along with the raising of scientific development and people's living standard, the application of pipeline in daily life and work is also apparent more important.But the height that is subject to ambient temperature owing to the pipeline after the fixed installation expands or shrinks, the active force of Chan Shenging destroys the normal use of pipeline easily therefrom, influence the normal operation of people's normal life and worker, ore deposit, enterprise, cause immeasurable loss to entire society.
The utility model is just towards the defective of above-mentioned objective reality and carry out deep research and draw, the purpose of this utility model just, a kind of expansion device of pipeline promptly will be provided, this device can relax expansion or the contraction that pipeline causes because of being subjected to variation of ambient temperature, makes pipeline not be subjected to the influence of ambient temperature.
Above-mentioned purpose of the present utility model is to realize by such technological scheme, and promptly the utility model adopts bulging ripple expansion device, and this device is made of a pipeline, and conventional flange all is with at the two ends of this pipeline, can be serially connected in other pipeline; The centre of described pipeline has a bulging ripple at least.
The described pipeline employing MC of system nylon material is made.
After the utility model adopts technique scheme, have the pipeline that relaxes after the fixed installation, guarantee that pipeline is not squeezed or stretches and breakage, ensures the proper functioning of pipeline preferably because of being subjected to variation of ambient temperature and expanding or shrinking.Simultaneously the utility model has more simple in structurely, installs simple and easyly, and is made by the MC nylon material, has more elasticity, improves tension, compression resistance greatly.
Accompanying drawing 1 is an example structure schematic representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is done further detailed description, as shown in the figure, only need be serially connected in pipeline 1 usefulness screw in the transportation pipeline and get final product.Because there is a bulging ripple 2 centre of pipeline 1; when the transportation pipeline expands because of the influence of ambient temperature or shrinks; extruding or stretching that bulging ripple 2 causes when just playing mitigation because of expansion or contraction make not cracky of pipeline, thereby effectively protect the proper functioning of pipeline.
Claims (2)
1, a kind of pipeline expansion device, this device is made of a pipeline, and conventional flange all is with at the two ends of this pipeline, can be serially connected in other pipeline, it is characterized in that the centre of described pipeline has a bulging ripple at least.
2, a kind of pipeline expansion device according to claim 1 is characterized in that described pipeline is to adopt the MC nylon material to make.
