Abstract
The utility model relates to the technical field of devices for absorbing extra deflection of a pipeline, in particular to an expansion joint. The expansion joint comprises an inner pipe and an outer pipe, wherein a first connecting flange is connected to one end of the inner pipe, a second connecting flange is connected to one end of the outer pipe, holes are formed in the upper side of the inner pipe and in the lower side of the inner pipe, holes are formed in the upper side of the outer pipe and in the lower side of the outer pipe, the inner pipe is arranged in the outer pipe in a sleeved mode, the inner pipe and the outer pipe are connected after bolts are screwed into coinciding holes in the inner pipe and in the outer pipe, and high-temperature-resistant layers made of rubber high-temperature inorganic materials are arranged on the inner wall of the inner pipe and on the inner wall of the outer pipe respectively. Due to the fact that the inner pipe is arranged in the outer pipe in the sleeved mode and the inner pipe and the outer pipe are connected after the bolts are screwed into the coinciding holes in the inner pipe and in the outer pipe, the length of the expansion joint can be adjusted freely according to the length of the pipeline, the problem that expansion joints need to be manufactured according to different lengths of pipelines is solved, cost is greatly saved, and manufacturing is simple.
Description
Technical field
The utility model relates to the technical field of the device of the extra displacement of extraction duct, especially a kind of expansion joint.
Background technique
The additional stress that expansion joint causes because of temperature difference and mechanical vibration for compensation, and be arranged on a kind of flexible structure on container shell or pipeline.Using at present the expansion joint on pipe is all to make expansion joint according to the length of different pipes, and the expansion joint on a kind of pipe can not re-use on another kind of pipe, and utilization ratio is not high and cause the waste of material.
The model utility content
In order to overcome the deficiency of existing technology, the utility model provides a kind of expansion joint.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of expansion joint, comprise inner and outer tubes, one end of described inner tube connects adpting flange one, described outer tube one end connects adpting flange two, top and the following hole that all is provided with of described inner and outer tubes, described inner tube is set in outer tube and by bolt and is screwed in the hole that coincides on inner and outer tubes and connects.
, according to another embodiment of the present utility model, comprise that further described inner and outer tubes inwall is provided with the high-temperature-resistant layer of being made by rubber high temperature inorganic material.
The beneficial effects of the utility model are, adopting inner tube to be set in outer tube and by bolt is screwed in the hole that coincides on inner and outer tubes and connects, can adjust freely according to the length of pipeline the length of expansion joint, do not need to make expansion joint according to the pipeline of different length, greatly saved cost and made very simple yet.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is front section view of the present utility model;
Fig. 2 is plan view of the present utility model.
1. inner tubes in figure, 2. outer tube, 3. adpting flange one, and 4. adpting flange two, 5. hole, 6. bolt, 7. high-temperature-resistant layer.
Embodiment
As depicted in figs. 1 and 2, a kind of expansion joint, comprise inner tube 1 and outer tube 2, one end of inner tube 1 connects adpting flange 1, outer tube 2 one ends connect adpting flange 24, top and the following hole 5 that all is provided with of inner tube 1 and outer tube 2, inner tube 1 be set in outer tube 2 and be screwed into inner tube 1 and outer tube be connected by bolt 6 on connect in the hole 5 that coincides, inner tube 1 and outer tube 2 inwalls are provided with the high-temperature-resistant layer 7 of being made by rubber high temperature inorganic material.
The utility model in use, one end of inner tube 1 connects adpting flange 1, outer tube 2 one ends connect adpting flange 24, inner tube 1 the other end is set in outer tube 2 the other ends, and the length free-extension that the pipe of expansion joint is installed is as required determined the length that inner tube 1 and outer tube 2 overlap, and be screwed into bolt 6 in the hole 5 of coincidence and connect, do not need to make expansion joint according to the pipeline of different length, greatly saved cost and made also very simple.
