Abstract
The utility model provides a connecting structure for a corrugated pipe and flanges. The connecting structure comprises the corrugated pipe and the flanges at the two ends of the corrugated pipe. Bolt holes are arranged on each flange. The corrugated pipe comprises a middle section corrugated pipe, a left section corrugated pipe and a right section corrugated pipe. The left section corrugated pipe and the right section corrugated pipe are respectively arranged on the two sides of the middle section corrugated pipe. An end part of the left section corrugated pipe and an end part of the right section corrugated pipe are respectively provided with a straight side section. An end part of each straight side section is fixedly connected with one flange. The diameter of each peak of the left section corrugated pipe is equal to the diameter of each peak of the right section corrugated pipe and is smaller than the diameter of each peak of the middle section corrugated pipe. The middle section corrugated pipe, the left section corrugated pipe, the right section corrugated pipe and the straight side sections are integrally formed. On one hand, since the distance between the flanges and the middle section corrugated pipe is increased, bolts can be conveniently installed on the flanges; and since the left section corrugated pipe and the right section corrugated pipe take an effect of reinforcing ribs, the strength of connection between the middle section corrugated pipe and the flanges is improved.
Description
Technical field
The utility model relates to the linkage structure of a kind of bellows and flange.
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 the bellows too closely is not easy to install the bolt that is used for adpting flange and flange, therefore must guarantee to have between flange and the bellows sufficiently long distance to be used for the bolt between the adpting flange with convenient the installation.Referring to Fig. 2, for guaranteeing have sufficiently long distance to be used for construction bolt between flange 4 and the bellows 5, the straight section 6 of bellows 5 of the prior art is longer; Because the wall thickness of bellows is all thinner; Generally have only δ=0.12～0.6mm, then the rigidity of straight section 6 is relatively poor, is easy to damage; If weld a bit of straight tube at the two ends of bellows, because the bellows wall thickness is thinner, the welding difficulty is very big, and the bellows of particularly little latus rectum can't weld between straight tube and the bellows at all.
The model utility content
The technical problem that the utility model solves is: the linkage structure of a kind of bellows and flange is provided, and construction bolt on flange easily, but also improved the join strength between bellows and the flange.
The technological scheme of the utility model is: the linkage structure of a kind of bellows and flange; Comprise bellows and the flange that is positioned at the bellows two ends; Said each flange is provided with and is used for interconnective screw between the flange; It is characterized in that said bellows comprises stage casing bellows, a left side section bellows and right section bellows, left side section bellows and right section bellows lay respectively at the both sides of stage casing bellows; The end of left side section bellows has straight section respectively with the end of right section bellows; The end of each straight section is fixedly connected with a described flange respectively, and the diameter of the diameter of each crest of left side section bellows and right each crest of section bellows is identical and less than the diameter of stage casing bellows crest, said stage casing bellows, left side section bellows, right section bellows and straight section are formed in one.
The quantity of left side section bellows crest equals the quantity of right section bellows crest.
The quantity of left side section bellows crest, the quantity of right section bellows crest all have two at least.
The peak-to-peak distance of the adjacent wave of stage casing bellows, the peak-to-peak distance of left side section bellows adjacent wave are all identical with the peak-to-peak distance of right section bellows adjacent wave.
The beneficial effect of the utility model is: the two ends of the utility model bellows in the stage casing are provided with left side section bellows and right section bellows; Article two, the bellows straight section is connected with the stage casing bellows through left side section bellows, right section bellows respectively; Extended the distance between bellows straight section and the stage casing bellows on the one hand; Thereby increased the distance between flange and the stage casing bellows; Construction bolt on flange because left side section bellows and right section bellows have the effect of stiffening rib, has therefore improved the join strength between stage casing bellows and the flange simultaneously easily.
