Abstract
The utility model discloses a large diameter rubber hose, which comprises a hose wall, a hose end connecting support body and a connector flange, wherein the hose wall is formed by an inner rubber layer, a middle rubber layer, an outer rubber layer, a layer of reinforcing bars and at least two layers of dual-thread cord fabrics; the reinforcing bars and the dual-thread cord fabrics are positioned inside the middle rubber layer, the reinforcing bars are disposed spirally inside the hose wall, the surfaces of the hose end connecting support body and the connector flange are coated by rubber layers. The large diameter rubber hose has the advantages that rigidity and high pressure resistant performance of the hose are enhanced by means of the factor that the reinforcing bars and the dual-thread cord fabrics are added into the middle rubber layer; the hose is not easy to damage, and the service life of the hose is prolonged; experiments verify that the bearing pressure of the hose is higher than 1.5 Mpa, the wear-resisting property of the hose is that the abrasion loss of the hose internal wall is <=1.2 (cm <3> / 6 KM), and the cumulative delivery capacity of the hose is higher than 8000 cubic meters, accordingly the service life of the hose is more than twice of the prior rubber hoses. The large diameter rubber hose is not only applied to material transportation in metallurgical and mining industries, but also suitable for liquid and gas delivery.
Description
Technical field:
The utility model relates to a kind of withstand voltage wear resistant conveying pipe road that is applicable to conveyance fluid, gas and logistics, specifically is a kind of large caliber rubber pipe of carrying ore materials that is mainly used in.
Background technique:
So-called large-diameter pipe is meant that generally its bore is greater than more than the 200mm, the used heavy caliber pipeline of the conveying of existing conveyance fluid, gas and logistics mainly contains two classes, one class is a metal tube, as steel pipe, this pipeline intensity height, good rigidly, high pressure resistant, directionality is good, but its exist corrosion-resistant difference and can not bending etc. deficiency; Another kind is a rubber pipe, and the advantage of this class pipe is corrosion-resistant, and is flexible, and the place adapts to, but it exists deficiencies such as rigidity is not enough, directionality difference.And in the smelting mining industry, especially used delivery pipe on large-size ball mill, majority is to use the large caliber rubber pipe, employed large caliber rubber pipe exists that poor rigidity, compressive strength are low on large-size ball mill at present, it bears pressure generally all less than 0.8Mpa, the defective of cracky, the accumulation transmission capacity will be changed less than 4000 cubes; Simultaneously, the metal flange that the rubber tube terminal interface is used is exposed outside, is corroded easily.Thereby cause existing large caliber rubber pipe short working life, the turnover rate height.
The model utility content:
The technical problems to be solved in the utility model is, a kind of have certain rigidity and compressive strength height, cracky not are provided, and is corrosion-resistant, the large caliber rubber pipe of long service life;
Technical solution of the present utility model is that a kind of large caliber rubber pipe with following structure is provided.
A kind of large caliber rubber pipe, comprise that tube wall, pipe end connect support and flange, it is characterized in that: described tube wall is made of inner glue layer, mesoglea and outer glue-line, one deck reinforcing bar, two layers of mariages cord at least, and described reinforcing bar and mariages cord are in the mesoglea.
After adopting above structure, compared with prior art, the utility model large caliber rubber pipe has the following advantages: owing in mesoglea, increased reinforcing bar and mariages cord, thus increased the rigidity and the high voltage performance of pipe, cracky has not increased its working life.Through test, it bears pressure more than 1.5Mpa, wear-resisting property: inner tube wall abrasion loss≤0.2 (cm
3/ 6KM), the accumulation transmission capacity reaches more than 8000 cubes, is more than the original rubber pipe twice in working life.The utility model large caliber rubber pipe not only is used for the mass transport of smelting mining industry, also is applicable to the conveying of liquids and gases class.
The utility model also has following feature and advantage:
Described reinforcing bar is the another spiral arrangement of enclosing the land of a circle in tube wall.This structure has not only increased the rigidity and the high voltage performance of pipe, but also has kept the flexible performance of rubber pipe, has used more convenient.
Described mariages cord is six layers.Use six layers, make the bend ability of tube wall better.
The surface that described pipe end connects support and flange is provided with the rubber layer parcel.This structure; mainly be that protection connection support and flange be not by other materials; as water, gas etc. directly be connected support and contact with flange; thereby strengthened the anti-corrosion capacity of flange; prolonged its working life, when installing and using, pipe docks with pipe; no longer need to use seal ring, connect convenient.

Fig. 2 is the utility model large caliber rubber tube wall cross-sectional structure schematic representation.
Shown in the figure: 1, pipe end connects support, and 2, flange, 3, inner glue layer, 4, mesoglea, 5, outer glue-line, 6, steel bar layer, 7, the mariages cord.
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model large caliber rubber pipe is described further:
Fig. 1, shown in Figure 2, a kind of large caliber rubber pipe, comprise that tube wall, pipe end connect support 1 and flange 2, tube wall is by inner glue layer 3, mesoglea 4 and outer glue-line 5 and be made of one deck reinforcing bar 6, two layers of mariages cord 7 at least, reinforcing bar 6 and mariages cord 7 are in the mesoglea 4, reinforcing bar 6 is the another spiral arrangement of enclosing the land of a circle in tube wall, and entwining inside and outside two layers of mariages cord 7 to be around reinforcing bar 6 extends axially arrangement.Connect support 1 and be arranged on tube opening, be used to connect pipe and flange 2, the surface that connects support 1 and flange 2 is provided with the rubber layer parcel, and the rubber layer that connects the surface of support 1 and flange 2 adopts sulfuration process to make.Present embodiment is: mariages cord 7 is six layers, and inner glue layer 3 adopts natural rubber and makes along the fourth mixglue, and outer glue-line 5 adopts natural rubber to make, and reinforcing bar 6 is selected the 70# carbon steel for use, and it is raw material that mariages cord 7 is selected polyamide fibre for use.
The key technical indexes of the utility model large caliber rubber pipe is as follows:
