Abstract
本发明提供一种波纹管的变径结构，包括中段波纹管、左段波纹管和右段波纹管，左段波纹管和右段波纹管分别位于中段波纹管的两侧，左段波纹管的端部和右段波纹管的端部分别具有直边段，左段波纹管波峰的直径与右段波纹管波峰的直径分别由中段波纹管至直边段方向逐渐减小。本发明在中段波纹管的两端设有左段波纹管和右段波纹管，而且由于左段波纹管波峰的直径与右段波纹管波峰的直径分别由中段波纹管至直边段方向逐渐减小，一方面延伸了波纹管直边段与中段波纹管之间的距离从而便于安装法兰的螺栓，同时提高了波纹管直边段与中段波纹管的连接强度，并且具有结构简单、制作成本低廉的有益效果。
The invention provides a variable diameter structure of bellows, which includes a middle section bellows, a left section bellows and a right section bellows, the left section bellows and right section bellows are respectively located on both sides of the middle section bellows, and the left section bellows The ends of the end and the right section of the bellows respectively have straight sections, and the diameters of the peaks of the left section of the bellows and the diameters of the right section of the bellows gradually decrease from the middle section of the bellows to the direction of the straight section. The present invention is provided with a left section bellows and a right section bellows at both ends of the middle section bellows, and because the diameter of the left section bellows crest and the diameter of the right section bellows crest respectively decrease gradually from the middle section bellows to the straight section direction On the one hand, it extends the distance between the straight section of the bellows and the middle section of the bellows to facilitate the installation of flange bolts, and at the same time improves the connection strength between the straight section of the bellows and the middle section of the bellows, and has a simple structure and low production cost. Inexpensive beneficial effects.
Description
Technical field
The present invention relates to a kind of bellows structure, relate in particular to a kind of variable-diameter structure of bellows.
Background technique
Bellows expansion joint comprises flange and bellows, and wherein the two ends of bellows are respectively equipped with straight section, and the straight section at bellows two ends is fixedly connected with a flange respectively.In vacuum piping and little latus rectum piping, the external diameter of bellows is greater than the mounting hole distance of flange, if straight section length is too short, distance between flange and bellows too closely is not easy to install the bolt for adpting flange, as longer in the bellows straight section, because the wall thickness of bellows is all thinner, generally only have δ=0.12～0.6mm, the rigidity of straight section is relatively poor, is easy to damage; If at a bit of straight tube of the two ends of bellows welding, because the bellows wall thickness is thinner, the welding difficulty is very large, the bellows of particularly little latus rectum can't weld between straight tube and bellows at all.
Summary of the invention
The technical problem that the present invention solves is: a kind of variable-diameter structure of bellows is provided, can facilitates, firm being connected with flange, and be convenient to bolt between mounting flange.
Technological scheme of the present invention is: a kind of variable-diameter structure of bellows, it is characterized in that, comprise stage casing bellows, left section bellows and right section bellows, left section bellows and right section bellows lay respectively at the both sides of stage casing bellows, the end of the end of left section bellows and right section bellows has respectively straight section, the diameter of the diameter of left section bellows crest and right section bellows crest is reduced gradually by stage casing bellows to straight section direction respectively, and described stage casing bellows, left section bellows, right section bellows and straight section are formed in one.
Left section bellows and right section bellows symmetry are positioned at the both sides of stage casing bellows.
The quantity of the quantity of left section bellows crest, right section bellows crest all has two at least.
The peak-to-peak distance of the adjacent wave of stage casing bellows, the left section peak-to-peak distance of bellows adjacent wave are all identical with the right section peak-to-peak distance of bellows adjacent wave.
the invention has the beneficial effects as follows: the present invention is provided with left section bellows and right section bellows at the two ends of stage casing bellows, article two, the bellows straight section is respectively by left section bellows, right section bellows is connected with the stage casing bellows, and because the diameter of left section bellows crest and the diameter of right section bellows crest are reduced gradually by stage casing bellows to straight section direction respectively, thereby extended on the one hand the bolt that distance between bellows straight section and stage casing bellows is convenient to mounting flange, improved simultaneously the join strength of bellows straight section and stage casing bellows, and have simple in structure, the beneficial effect that fabricating cost is cheap.
