Abstract
The utility model relates to a one-way ripple compensating tube which comprises an extension tube and a guide cylinder. The extension tube is provided with a corrugated tube, an upper connecting tube and a lower connecting tube, wherein the upper end of the corrugated tube and the lower end of the corrugated tube are respectively connected with the upper connecting tube and the lower connecting tube in an airtight mode. The guide cylinder is arranged in the extension tube in a sliding mode. The guide cylinder comprises a fixed end and a unfixed end, wherein the end mouth of the fixed end is fixedly connected with an inner wall of the lower connecting tube arranged on the extension tube. Two ends of the extension tube are respectively and fixedly connected with a flange. The one-way ripple compensating tube is simple in structure and extensive in application.
Description
Technical field
The utility model relates to a kind of expansion pipe, particularly a kind of unidirectional ripple compensation pipe.
Background technique
As everyone knows, expansion pipe is equivalent to a kind of compensating element, uses bellows to be because of easily bending of bellows, to elongate and compression at expansion pipe, thereby the displacement pipeline is played compensating action.Because bellows has numerous folds, shelters evil people and countenance evil practices easily, thereby causes various hygienic issues.Moreover because the rigidity of bellows is inadequate, expansion pipe deforms easily.Although the bellows that adopts rock-steady structure is arranged at present, these rock-steady structures are all relatively complicated, and affect the attractive in appearance of expansion pipe.
The model utility content
The purpose of this utility model provide a kind of simple in structure, use widely unidirectional ripple compensation pipe.
The technological scheme that realizes the utility model purpose is: the utlity model has telescopic pipe and guide shell; Described telescopic pipe has bellows, upper connecting tube and lower linking tube, is connected with lower linking tube with upper connecting tube respectively and is connected in the up and down two ends of bellows; Described guide shell is slidingly arranged in the telescopic pipe; Described guide shell has fixed end and on-fixed end, and the inwall of the lower linking tube on the port of fixed end and the telescopic pipe is fixedly connected with.
The two ends of above-mentioned telescopic pipe all are fixedly connected with a flange.
Above-mentioned flange is square flange.
The port of the fixed end of above-mentioned guide shell is horn mouth.
Above-mentioned telescopic pipe and guide shell all are stainless steels.
The utlity model has positive effect: (1) the utility model compensates by the bellows on the telescopic pipe, carries out water conservancy diversion by guide shell, and is simple in structure; (2) the utility model adopts stainless steel, and antirust ability is remarkable, uses extensively.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model, wherein according to specific embodiment also by reference to the accompanying drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is worm's eye view of the present utility model.
Embodiment
See Fig. 1 and Fig. 2, the utlity model has telescopic pipe 1 and guide shell 2; Described telescopic pipe 1 has bellows 11, upper connecting tube 12 and lower linking tube 13, is connected airtight the connection with lower linking tube with upper connecting tube 12 respectively in the up and down two ends of bellows 11; Described guide shell 2 is slidingly arranged in the telescopic pipe 1; Described guide shell 2 has fixed end and on-fixed end, and the inwall of the lower linking tube 13 on the port of fixed end and the telescopic pipe 1 is fixedly connected with; The two ends of described telescopic pipe 1 all are fixedly connected with a square flange (3); The port of the fixed end of described guide shell 2 is horn mouth; Described telescopic pipe 1 and guide shell 2 all are stainless steels.
Above-described specific embodiment; the purpose of this utility model, technological scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
