Abstract
The utility model relates to a fluid transfer hose, belonging to the technical field of transfer pipeline flexible connecting pipes and aiming at providing the fluid transfer hose with light weight, favorable flexibility, favorable abrasion resistance and favorable weatherability by reasonably improving a protective layer on account of the disadvantages of the current hose. The hose comprises a corrugated pipe, a braided structure enhancement layer wrapped on the corrugated pipe and a protective layer loosely sheathed outside the enhancement layer; the protective layer is formed by spiral wrapping tapes with S-shaped cross sections; both ends of each S-shape cross section are respectively buckled with a corresponding structure of an adjacent wrapping tape; and the end of the protective layer is fixedly connected with a connecting pipe at the end of the corrugated pipe through a lining ring. The fluid transfer hose has light weight, ideal flexibility and vibration damping and noise reduction function, keeps the efficacy of compensation displacement of the hose, can satisfy the requirements of favorable abrasion resistance and favorable weatherability and dramatically prolongs the service life.
Description
Technical field
The utility model relates to a kind of flexible hose, and especially a kind of fluid-conveying hose that is mainly used in the medium pipelines such as gas turbo-generator set delivery of fuel gas, steam, oil plant belongs to delivery line hose connector technical field.
Background technique
The flexible pipe of media such as gas turbo-generator set delivery of fuel gas, steam, oil plant not only requires pressure-bearing height, corrosion-resistant; and different with conventional flexible pipe be; its outside need is provided with protective layer; to prevent the flexible pipe wearing and tearing, avoid of the influence of the high-pressure spray of dielectric leakage generation to personnel and working environment.Understand according to the claimant; this type of flexible pipe protective layer in the past all adopts and applies the thick vulcanized rubber of 3～5mm; its shortcoming be obviously increased the flexible pipe deadweight, reduced flexible pipe flexibility, reduced the compensation rate of flexible pipe, and the wear resistance of rubber, weatherability are relatively poor, so working life is shorter.
The model utility content
The purpose of this utility model is: the shortcoming that exists at above existing flexible pipe, by reasonable improvement to protective layer, propose a kind of in light weight, the fluid-conveying hose of pliability, wear resistance, good weatherability.
In order to reach above purpose, fluid-conveying hose of the present utility model comprises bellows, is wrapped in the braiding structure enhancement layer on the bellows, and pine is enclosed within the outer protective layer of enhancement layer; Described protective layer is made of the S-shaped spiral tape wrap in cross section; The two ends of described S tee section fasten mutually with the counter structure of adjacent spiral tape wrap respectively; Fixedly connected with the adapter of corrugated tube end by grommet in the end of described protective layer.
Because protective layer of the present utility model adopts S tee section take-up strap, and is therefore in light weight; And exist the fastening gap to guarantee that protective layer has ideal flexible and vibration and noise reducing effect between two take-up straps, kept the usefulness of flexible pipe compensate for displacement; Take-up strap is easy to adopt material such as stainless steel to make, and therefore can satisfy the requirement of wear resistance, good weatherability fully, significant prolongation working life.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is an embodiment's of the utility model a structural representation.
Embodiment
Embodiment:
The fluid-conveying hose of present embodiment is used for generator set; its structure as shown in Figure 1; mainly weave enhancement layer 2, and the stainless steel lightweight protective layers 3 that pine is enclosed within outside the enhancement layer 2 constitute by the metal bellows 1 of stainless steel, the Stainless Steel Wire that is wrapped on the bellows 1.Enhancement layer 2 plays the effect that strengthens the bellows withstand voltage properties.Protective layer 3 is made of the spiral tape wrap, plays a part wear-resisting and stop to leak the high-pressure spray that produces.Revolve tape wrap by the Stainless Steel Band calendaring molding, the cross section is S-shaped, and during winding, the two ends of S tee section fasten mutually with the counter structure of adjacent spiral tape wrap respectively, therefore constitutes the flexible tubular protective layer 3 that labyrinth-like fastens the cross section.Article two, have certain gap that axially and radially fastens after take-up strap fastens, thereby have ideal flexible, keep the usefulness of flexible pipe compensate for displacement.
The termination of bellows 1 takes over 5 to being welded with, and the two ends of adapter 5 all have expansion limit seam, and cylindrical is with joint (flange) 6.The termination of enhancement layer 2 is fixed on the cylindrical of adapter 5 by the snap ring banding.
Fixedly connected with the adapter 5 of bellows 1 end by the stainless steel grommet 4 of annular in the end of protective layer 3.The external diameter of grommet 4 and internal diameter match with the internal diameter of protective layer 3 and the external diameter of adapter 5 respectively; thereby with inner hole sleeve outside the adapter 5 of hose end, cylindrical is embedded in the mode in protective layer 3 endoporus, by the seam weldering protective layer 2 and bellows are taken over 5 and are fixed together.
Facts have proved that the fluid-conveying hose of present embodiment not only has desirable compensate for displacement, vibration and noise reducing effect, and have outstanding advantages such as pressure-bearing height, corrosion-resistant, in light weight, wear-resisting and good weatherability.
In addition to the implementation, the utility model can also have other mode of executions.Its material is not limited to stainless steel, and purposes also is not limited to generator set, and joint both can be a flanged joint, also can be inipple.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
