Abstract
The utility model discloses a kind of high-strength reducing bellows, comprise body, body comprises outward corrugated tube and interior pipe, many the steel bands axially arranged circumferentially evenly are provided with between outward corrugated tube and interior pipe, steel band is fixedly connected with interior pipe and outward corrugated tube, outward corrugated tube comprises left end section bellows, left section of bellows, stage casing bellows, right section of bellows and right-hand member section bellows, left end section bellows, right-hand member section bellows and stage casing bellows are straight section, the crest of outward corrugated tube respectively by left section of bellows and right section of bellows respectively to left end section bellows, the straight section of right-hand member section bellows and stage casing bellows reduces gradually.Arranging of this high-strength reducing bellows facilitates the support in the middle of bellows body to fix, and prevents bellows long-time middle sagging, and promotes the intensity of this bellows, extend the working life of bellows.
Description
Technical field
The utility model relates to a kind of bellows, particularly relates to a kind of high-strength reducing bellows.
Background technique
It is large footpath that existing variable-diameter corrugated pipe mostly is in the middle of the path of two ends, and such setting is that the installation at conveniently bellows two ends is fixed.But more existing variable-diameter corrugated pipes due to length longer, self is heavier, strength deficiency, time unsettled in the middle of two ends are fixing, often cause in the middle of bellows sagging, after long-time, easily cause phenomenon of rupture, and due to the ripple setting in the middle of bellows, make intermediate portion be difficult to support with support or flange.Therefore need development one can make middle convenient support, and greatly strengthen the variable-diameter corrugated pipe of body intensity.
Model utility content
For solving the problems of the technologies described above, the utility model devises a kind of high-strength reducing bellows.
The utility model adopts following technological scheme:
A kind of high-strength reducing bellows, comprise body, body comprises outward corrugated tube and interior pipe, many the steel bands axially arranged circumferentially evenly are provided with between outward corrugated tube and interior pipe, steel band is fixedly connected with interior pipe and outward corrugated tube, outward corrugated tube comprises left end section bellows, left section of bellows, stage casing bellows, right section of bellows and right-hand member section bellows, left end section bellows, right-hand member section bellows and stage casing bellows are straight section, the crest of outward corrugated tube respectively by left section of bellows and right section of bellows respectively to left end section bellows, the straight section of right-hand member section bellows and stage casing bellows reduces gradually.
As preferably, described left end section bellows, left section of bellows, stage casing bellows, right section of bellows and right-hand member section bellows are formed in one.
As preferably, described steel band and interior pipe and outward corrugated tube bond fixing respectively by binding resin.
Compared with prior art, the left end section bellows of this high-strength reducing bellows, right-hand member section bellows and stage casing bellows are straight section, the crest of outward corrugated tube respectively by left section of bellows and right section of bellows respectively to left end section bellows, the straight section of right-hand member section bellows and stage casing bellows reduces gradually, such design is just convenient makes supporting structure at bellows two ends and centre flange, the support of bellows is facilitated to fix, prevent bellows long-time middle sagging, extend the working life of bellows, and between outward corrugated tube and interior pipe, be circumferentially evenly provided with many steel bands axially arranged, the intensity of this bellows is greatly promoted by the setting of steel band, the working life of further prolongation bellows.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is a kind of left view of Fig. 1;
In figure: 1, outward corrugated tube, 2, interior pipe, 3, steel band, 4, left end section bellows, 5, left section of bellows, 6, stage casing bellows, 7, right section of bellows, 8, right-hand member section bellows.
Embodiment
Below by specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described specifically:
Embodiment: as shown in Figures 1 and 2, a kind of high-strength reducing bellows, comprise body, body comprises outward corrugated tube 1 and interior pipe 2, eight steel bands 3 axially arranged circumferentially evenly are provided with between outward corrugated tube and interior pipe, steel band is fixedly connected with interior pipe and outward corrugated tube, outward corrugated tube comprises left end section bellows 4, left section of bellows 5, stage casing bellows 6, right section of bellows 7 and right-hand member section bellows 8, left end section bellows, right-hand member section bellows and stage casing bellows are straight section, the crest of outward corrugated tube respectively by left section of bellows and right section of bellows respectively to left end section bellows, the straight section of right-hand member section bellows and stage casing bellows reduces gradually, left end section bellows, left section of bellows, stage casing bellows, right section of bellows and right-hand member section bellows are formed in one, steel band and interior pipe and outward corrugated tube bond fixing respectively by binding resin.
The left end section bellows of this high-strength reducing bellows, right-hand member section bellows and stage casing bellows are straight section, the crest of outward corrugated tube respectively by left section of bellows and right section of bellows respectively to left end section bellows, the straight section of right-hand member section bellows and stage casing bellows reduces gradually, such design is just convenient makes supporting structure at bellows two ends and centre flange, the support of bellows is facilitated to fix, prevent bellows long-time middle sagging, extend the working life of bellows, and between outward corrugated tube and interior pipe, be circumferentially evenly provided with eight steel bands axially arranged, the intensity of this bellows is greatly promoted by the setting of steel band, the working life of further prolongation bellows.
Above-described embodiment is one of the present utility model preferably scheme, not does any pro forma restriction to the utility model, also has other variant and remodeling under the prerequisite not exceeding the technological scheme described in claim.
