Technical Field

The utility model relates to the technical field of hoses, especially, relate to a plastic hose.

Background

The prior hose products mainly comprise rubber hoses, nylon hoses, plastic hoses, rubber and plastic hoses and the like, and the hose products mainly comprise single-raw-material hoses, mixed-raw-material hoses, hoses with reinforcing layers and the like in terms of structure.

The existing hose is mainly used for conveying hydraulic fluid with certain pressure and temperature, such as alcohol, oil, emulsion, water or slurry, and the like, and in the process of long-distance conveying, due to the existence of conveying pressure, the hose is very easy to stretch, so that the pipe wall is thinned, the bulge phenomenon is caused, and the normal use is influenced; in a serious situation, the steel pipe can be broken, and production safety accidents are caused.

Therefore, there is a need for a plastic hose that can prevent the occurrence of bulge, increase the conveying distance, and improve the safety in use.

In order to solve the technical problem, the technical scheme of the utility model is that:

a plastic hose comprises an inner layer, a middle layer and a surface layer which are arranged from inside to outside in sequence;

the outer surface of the inner layer is spirally wrapped with a reinforcing steel wire, and the middle layer is wrapped on the outer side of the reinforcing steel wire;

the outer surface of the middle layer is wrapped with reinforcing fibers, and the reinforcing fibers comprise a fiber net and a plurality of warp yarns;

the surface layer is coated on the outer side of the reinforced fiber;

the middle layer and the inner layer are bonded into a whole through the gaps of the reinforced steel wires, and the surface layer and the middle layer are bonded into a whole through the gaps of the reinforced fibers.

Preferably, a plurality of the warps are circumferentially equally spaced.

Preferably, the warp threads extend in the same direction as the axial direction of the hose.

Preferably, the number of the warps is more than or equal to eight.

Preferably, the fiber net is coated on the outer side of the warp.

Preferably, the reinforcing fiber is made of terylene or chinlon.

Preferably, the reinforced steel wire is a galvanized steel wire, and the pitch of the reinforced steel wire is 5mm or more than 5 mm.

Preferably, the diameter of the reinforcing steel wire is 0.8mm or more and 0.8mm or more.

Preferably, the inner layer, the middle layer and the surface layer are made of the same material and are all made of PVC or PE.

After the technical scheme is adopted, the beneficial effects of the utility model are that:

in the utility model, the reinforcing steel wire is spirally wrapped on the outer surface of the inner layer, the middle layer is wrapped on the outer side of the reinforcing steel wire, and the reinforcing steel wire is spiral, so that compared with the existing woven mesh-shaped steel wire, the use amount of the steel wire is reduced, the weight of the hose is reduced, the strength of the hose is enhanced, and the production cost is reduced; the surface package in intermediate level has reinforcing fiber, and reinforcing fiber includes fibre web and many warp, and warp can strengthen the radial intensity of hose, prevents that the fluid from taking place the drawing at remote transport's in-process, appearing the swell phenomenon, and reinforcing hose intensity improves the security of hose.

To sum up, the utility model provides a pair of plastic hose can be in fluid transportation process, and the reinforcing is carried the distance, prevents to take place tensile, prevents to appear the swell phenomenon, improves the result of use of product, improves the security.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 and 2, the present invention includes an inner layer 1, an intermediate layer 3 and a surface layer 5, which are sequentially arranged from inside to outside.

The outer surface of the inner layer 1 is spirally wrapped with a reinforcing steel wire 2, and the middle layer 3 is wrapped on the outer side of the reinforcing steel wire 2. The reinforced steel wire 2 is a galvanized steel wire, the pitch of the reinforced steel wire 2 is 5mm or more than 5mm, and the diameter of the reinforced steel wire 2 is 0.8mm or more than 0.8 mm.

The outer surface of intermediate level 3 is wrapped with reinforcing fiber, and reinforcing fiber's material is dacron or polyamide fibre, and reinforcing fiber includes fibre web 41 and many warp 42, and fibre web 41 is the inside fibre web 41 of crisscross rhombus drill way 43 of weaving into in slant, and fibre web 41 cladding is in warp 42's the outside.
