Abstract
The utility model relates to a special-shaped metal corrugated pipe, which is formed by a corrugated pipe with two semicircular sides, and a corrugated body with a rectangular middle. The special-shaped metal corrugated pipe formed by the corrugated pipe with two semicircular sides and the corrugated body with the rectangular middle is used for replacing a round metal corrugated pipe, so that the working surface of the metal corrugated pipe is increased in the situation that the diameter of the circle is ensured not to be increased; the working volume is increased through the working surface multiplied by the height (namely, the corrugation number of the corrugated pipe), thereby leading the corrugated pipe to be capable of being used in places with narrow environmental spaces.
Description
Technical field
The utility model relates to a kind of industrial element, specifically a kind of special-shaped metal bellows that can be used as damper element, compensating element and pipeline connecting parts use.
Background technique
Present metal bellows mainly is a round structure, be characterized in that production and processing is easy, pressurized is even during work, but in some specific occasion, restricted by external condition, the diameter of metal bellows can not increase, at this moment the working surface of wavy metal (downward projection area) just can not increase, thereby influenced working efficiency, as the wavy metal expander of using as the large-scale power transformer compensation volume, owing to need to require the volume of compensation bigger by the parts of metal bellows processing, if adopt the metal bellows of existing round structure, certainly will increase the diameter of metal bellows, also increase its area occupied simultaneously, use extremely inconvenience for the narrow place of environment space.
Summary of the invention
In view of the foregoing, the purpose of this utility model provides a kind of special-shaped metal bellows that can increase working sections, the narrow local use of simultaneous adaptation environment space.
The purpose of this utility model is achieved in that this metal bellows, and it is to be formed by both sides semicircular in shape bellows, the centre corrugated body that is rectangle.
The utility model has the advantages that utilize both sides semicircular in shape bellows, centre to be rectangle special-shaped metal bellows that corrugated body forms replaces former circular metal bellows, can guarantee like this under the situation that diameter of a circle does not increase, increase the working surface of metal bellows, being multiplied by height (being the wave number of bellows) has just increased swept volume, thereby satisfies narrow local use of environment space.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the plan view of Fig. 1.
Embodiment
Shown in Fig. 1-2, this abnormal shape metal bellows is to be rectangular corrugated body 2 by both sides semicircular in shape bellows 1,3, centre to form.The special-shaped metal bellows that both sides semicircular in shape bellows 1,3, centre are rectangular corrugated body 2 formation is once to make, shape such as runway shape.This abnormal shape metal bellows can be used as the expansion core body of transformer oil conservater compensation volume, because core body is narrower, institute takes up space less, if increase compensation volume, the height (being the wave number of bellows) that only needs to improve bellows gets final product, and is suitable for the large-scale power transformer oil conservater.
Claims (1)
1. special-shaped metal bellows is characterized in that: it is to be formed by both sides semicircular in shape bellows, the centre corrugated body that is rectangle.
