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 loop is evenly distributed with by corrugated vertically between steel band and interior pipe, the cross section of steel loop is arc-shaped, 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.The structure of this high-strength reducing bellows facilitates the support in the middle of bellows to fix, and can prevent bellows transverse breakage, the intensity of this bellows of General Promotion, extend the working life of bellows further.
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 loop is evenly distributed with by corrugated vertically between steel band and interior pipe, the cross section of steel loop is arc-shaped, 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, be socketed with PE corrugated ring outside described steel loop, PE corrugated ring is fixedly connected with steel band respectively with interior pipe, steel loop, and steel loop is fixedly connected with steel band, and steel band is fixedly connected with outward corrugated tube.
As preferably, described PE corrugated ring and steel band and steel loop bond fixing respectively by binding resin.
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.
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, steel loop is evenly distributed with by corrugated vertically between steel band and interior pipe, the cross section of steel loop is arc-shaped, the design of the steel loop distributed by steel band and corrugated strengthens the intensity of this bellows greatly, interior pipe and the stressed of outward corrugated tube can carry out flexible buffering by undulatory steel loop, improve the resistivity of bellows in the face of impacting, steel band promotes bellows croos strength, bellows transverse breakage can be prevented, the intensity of this bellows of General Promotion, 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, steel loop, 5, PE corrugated ring, 6, left end section bellows, 7, left section of bellows, 8, stage casing bellows, 9, right section of bellows, 10, 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 loop 4 is evenly distributed with by corrugated vertically between steel band and interior pipe, the cross section of steel loop is arc-shaped, outward corrugated tube comprises left end section bellows 6, left section of bellows 7, stage casing bellows 8, right section of bellows 9 and right-hand member section bellows 10, 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, PE corrugated ring 5 is socketed with outside steel loop, PE corrugated ring and interior pipe, steel loop is fixedly connected with respectively with steel band, steel loop is fixedly connected with steel band, steel band is fixedly connected with outward corrugated tube, PE corrugated ring and steel band and steel loop bond fixing respectively by binding resin, 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.
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, steel loop is evenly distributed with by corrugated vertically between steel band and interior pipe, the cross section of steel loop is arc-shaped, the design of the steel loop distributed by steel band and corrugated strengthens the intensity of this bellows greatly, interior pipe and the stressed of outward corrugated tube can carry out flexible buffering by undulatory steel loop, improve the resistivity of bellows in the face of impacting, steel band promotes bellows croos strength, bellows transverse breakage can be prevented, the intensity of this bellows of General Promotion, 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.
