Abstract
A durable fuel oil return pipe relates to the technical field of oil pipes for machinery and comprises a rubber pipe layer (1), a heat insulation layer (2) and a braided fabric layer (3), wherein the heat insulation layer (2) is arranged outside the rubber pipe layer (1), and the braided fabric layer (3) is arranged outside the heat insulation layer (2). The durable fuel oil return pipe is simple in structure, reduces pipe diameter, simultaneously adopts twice coating, is not affected by weather and environments in use due to the weaving layer arranged on the outside, and is long in service life and stable in performance.
Description
Technical field:
The utility model relates to machinery and uses the oil pipe technical field, is specifically related to a kind of durable return flow oil pipe.
Background technique:
The using scope of oil pipe is extremely extensive, all be unable to do without the use of oil pipe on the present big factoried machinery, and the return flow oil pipe is wherein a kind of.Traditional return flow oil pipe is common rubber tubing, and caliber is bigger, and long-term use makes return tube expand with heat and contract with cold because of the effect of back weather and environment; Cause the rubber pipe surface can produce a lot of crackles, in the oil return process, be easy to occur oil leakage phenomenon, under the lower situation of temperature; It is very hard and more crisp that rubber pipe can become; Not flexible, fracture easily, make troubles to work.
The model utility content:
The purpose of the utility model provides a kind of durable return flow oil pipe, and it is simple in structure, when dwindling caliber, adopts kiss-coating twice, and the outside is provided with organization level, uses the influence that does not receive weather and environment, longer service life, and performance is more stable.
In order to solve the existing problem of background technique, the utility model is to adopt following technological scheme: it comprises rubber pipe layer 1, thermal-protective coating 2 and braid layer 3; Rubber pipe layer 1 arranged outside has thermal-protective coating 2, and thermal-protective coating 2 arranged outside have braid layer 3.
The utility model adopts 200% to shrink, and carries out kiss-coating twice.It is simple in structure, when dwindling caliber, adopts kiss-coating twice, and the outside is provided with organization level, uses the influence that does not receive weather and environment, longer service life, and performance is more stable.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the sectional view of the utility model.
Embodiment:
Referring to Fig. 1-2, this embodiment is to adopt following technological scheme: it comprises rubber pipe layer 1, thermal-protective coating 2 and braid layer 3; Rubber pipe layer 1 arranged outside has thermal-protective coating 2, and thermal-protective coating 2 arranged outside have braid layer 3.
This embodiment adopts 200% to shrink, and carries out kiss-coating twice.It is simple in structure, when dwindling caliber, adopts kiss-coating twice, and the outside is provided with organization level, uses the influence that does not receive weather and environment, longer service life, and performance is more stable.
