Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

An object of this embodiment is to provide a rubber hose, through cladding insulating layer on the lateral wall of rubber tube body to avoid the damage to the rubber tube body that leads to on external high temperature transmits to the rubber tube body, prolong this rubber hose's life.

Hereinafter, embodiments will be described with reference to the drawings. The embodiments described below do not limit the scope of the invention described in the claims. Further, the entire contents of the configurations shown in the following embodiments are not limited to those necessary as a solution of the invention described in the claims.

Referring to FIGS. 1-3, schematic structural views of rubber hoses in some exemplary embodiments are shown. The rubber hose that this embodiment provided includes rubber tube body 1 and insulating layer 2, and the cladding of insulating layer 2 is on the lateral wall of rubber tube body 1, and insulating layer 2 is used for keeping apart rubber tube body 1 and external environment. So set up, through insulating layer 2 that the cladding one deck has thermal-insulated effect on the lateral wall of rubber tube body 1, keep apart rubber tube body 1 and its surrounding environment, avoid the high temperature transmission in the surrounding environment to give rubber tube body 1, guarantee that the temperature of rubber tube body 1 is not too high, delay the ageing of rubber hose, prolong this rubber hose's life.

In this embodiment, the heat insulation layer 2 is made of asbestos. The asbestos has high fire resistance, electrical insulation and thermal insulation, is an important fireproof, insulating and heat-insulating material, is arranged outside the rubber tube body 1 as the heat-insulating layer 2, can effectively isolate high temperature in the external environment from being transferred to the rubber tube body 1, and has a good heat-insulating effect.

In the preferred scheme of this implementation, still be provided with the mounting in the outside of insulating layer 2 for the insulating layer 2 outside to rubber tube body 1 is consolidated, guarantees the reliability of being connected between insulating layer 2 and the rubber tube body 1, in this rubber hose use, avoids insulating layer 2's unexpected problem of droing, increase of service life.

In implementing, above-mentioned mounting can be metal mesh 3, and the inner circle size of metal mesh 3 is the same with the outer lane size of insulating layer 2, and the outside of insulating layer 2 is located and closely laminates with insulating layer 2 to 3 covers of metal mesh, avoids rocking of insulating layer 2 between metal mesh 3 and rubber tube body 1, further guarantees insulating effect of insulating layer 2.

In practice, the metal mesh 3 is made of stainless steel, which has excellent corrosion resistance and toughness in a wide temperature range, so that the rubber hose has a long service life in a severe environment. In order to further increase the corrosion resistance of the metal mesh 3, paint may be sprayed on the metal mesh 3 to isolate it from the external environment.

In the implementation, the net shape of metal mesh 3 is the rhombus, elegant appearance, and the rhombus net produces deformation easily, and the length and the diameter of the cylindrical metal mesh 3 that the rhombus net encloses can change, when taking place expend with heat and contract with cold, can adjust the size by oneself, avoids the damage of metal mesh 3.
