Abstract
The invention discloses a double-piece type expansion joint which comprises a first expansion body and a second expansion body. The first expansion body comprises a first pipeline and a first spherical shell body, the second expansion body comprises a second pipeline and a second spherical shell body, and the first expansion body and the second expansion body are communicated through the first pipeline and the second pipeline, and are arranged in an expansion connecting mode. Through the mode, the double-piece type expansion joint can improve the pressure bearing capacity of the expansion bodies, and is reasonable in structure, convenient to mount and maintain, good in sealing performance, capable of resisting high temperature and corrosion and is wider in application range.
Description
Technical field
The present invention relates to the end socket technical field, particularly relate to a kind of biplate type expansion joint.
Background technique
The end socket expansion joint also is slip joint traditionally, or corrugated expansion joint, be to utilize effective dilatation of the elastic element of corrugated expansion joint to absorb pipeline, conduit or the container a kind of compensation device by former thereby the dimensional changes that produces such as expand with heat and contract with cold, belong to a kind of end socket compensating element.
In prior art, expansion joint generally is monolithic type, its restricted application, and bearing capacity is also limited, and sealing is not good, while using under the environment such as high temperature, is easy to be damaged.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of biplate type expansion joint, can improve the bearing capacity of expander, and rational in infrastructure, convenient for installation and maintenance, good seal performance, can be high temperature resistant, corrosion-resistant, and Applicable scope is also more extensive.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of biplate type expansion joint is provided, comprise: the first expander and the second expander, described the first expander comprises the first pipeline and the first spherical shell, described the second expander comprises second pipe and the second spherical shell, described the first expander and the second expander are interconnected by the first pipeline and second pipe, and described the first expander and the second expander are the expanded joint setting.
In a preferred embodiment of the present invention, the setting that is formed in one of described the first pipeline and the first spherical shell, the setting that is formed in one of described second pipe and the second spherical shell.
In a preferred embodiment of the present invention, described the first expander and the second expander are for being symmetrical arranged.
In a preferred embodiment of the present invention, the pipe thickness of described the first pipeline and second pipe is 10mm ~ 50mm.
In a preferred embodiment of the present invention, the internal diameter of described the first spherical shell and the second spherical shell is 2000mm ~ 4500mm.
The invention has the beneficial effects as follows: biplate type expansion joint of the present invention can improve the bearing capacity of expander, rational in infrastructure, convenient for installation and maintenance, and good seal performance can be high temperature resistant, corrosion-resistant, and Applicable scope is also more extensive.

In accompanying drawing, the mark of each parts is as follows: 1, the first pipeline, the 2, first spherical shell, 3, second pipe, the 4, second spherical shell, the 5, first expander, the 6, second expander.
Embodiment
Below will the technological scheme in the embodiment of the present invention be clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Embodiment based in the present invention, those of ordinary skills, not making all other embodiments that obtain under the creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of biplate type expansion joint comprises: the first expander 5 and the second expander 6, and described the first expander 5 comprises the first pipeline 1 and the first spherical shell 2, described the second expander 6 comprises second pipe 3 and the second spherical shell 4.
Particularly, the setting that is formed in one of described the first pipeline 1 and the first spherical shell 2, the setting that is formed in one of described second pipe 3 and the second spherical shell 4, can improve the bearing capacity of expander like this.
Described the first expander 5 and the second expander 6 are interconnected by the first pipeline 1 and second pipe 3, and described the first expander 5 and the second expander 6 are for being symmetrical arranged.
Described the first expander 5 and the second expander 6 are the expanded joint setting, and rational in infrastructure, convenient for installation and maintenance, good seal performance, can be high temperature resistant, corrosion-resistant.
Particularly, the pipe thickness of described the first pipeline 1 and second pipe 3 is 10mm ~ 50mm, and the internal diameter of described the first spherical shell 2 and the second spherical shell 4 is 2000mm ~ 4500mm, and its compact structure is reasonable, and Applicable scope is also more extensive.
The beneficial effect of biplate type expansion joint of the present invention is:
Can improve the bearing capacity of expander, rational in infrastructure, convenient for installation and maintenance, good seal performance, can be high temperature resistant, corrosion-resistant, and Applicable scope is also more extensive.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or directly or indirectly be used in other relevant technical field, all in like manner be included in scope of patent protection of the present invention.
