Description

Wear-resistant hose

Technical Field

The utility model relates to the technical field of hoses, in particular to a wear-resistant hose.

Background

The hose is widely applied to the fields of industry, agriculture, fire protection and the like, when the hose is used, the hose is dragged on the ground, and the inner liner layer of the hose is worn after the woven layer covered on the outer layer of the hose is worn, so that the hose is easy to break and lose efficacy.

In the prior art, a layer of woven layer is worn out of a hose or a new wear-resistant layer is added, the outer woven layer is worn out firstly when the hose with the double-layer woven layer is dragged on the ground, the inner woven layer is worn out after the outer woven layer is worn out, the inner hose is worn out after the double-layer woven layer is worn out, for example, chinese patent with publication number CN 110202845A discloses a double-woven layer high-pressure wear-resistant hose, and the wear resistance of the hose is improved by arranging the double-layer woven layer and the wear-resistant layer on the outermost layer.

However, the weaving layer is worn out earlier by warp when the hose drags on ground, and the warp of outer weaving layer and interior weaving layer is 2D polyester filament, and although double-deck weaving layer can increase certain wear resistance, but 2D polyester filament will lead to the inner liner of hose impaired once wearing out, and the hose breaks and leaks, and newly increases wearing layer and can increase manufacturing cost at the hose outermost layer.

Please refer to fig. 1-2. Other advantages and effects of the present utility model will become apparent to those skilled in the art from the following disclosure, which describes the embodiments of the present utility model with reference to specific examples.

It should be understood that the structures, proportions, sizes, etc. shown in the drawings are for illustration purposes only and should not be construed as limiting the utility model to the extent that it can be practiced, since modifications, changes in the proportions, or adjustments of the sizes, which are otherwise, used in the practice of the utility model, are included in the spirit and scope of the utility model which is otherwise, without departing from the spirit or scope thereof. Also, the terms "left", "right", "upper", "lower" and "a" are used herein for descriptive purposes only and are not intended to limit the scope of the utility model as embodied or construed in any manner without substantially altering the technical context.

As shown in fig. 1, a wear-resistant hose 1 achieves an effect of enhancing wear resistance by improving the manner of braiding a braid. The wear-resistant hose 1 comprises an inner liner 11 and a woven layer 12, wherein the inner liner 11 is positioned on the innermost layer, the woven layer 12 is covered on the inner liner 11, and the woven layer 12 is used for protecting the inner liner 11.

Specifically, the woven layer 12 is double-layered under the actual requirement of the abrasion-resistant hose 1, so as to provide double-layered protection for the inner liner 11, and the woven layer 12 can be additionally covered with an abrasion-resistant layer, so that the abrasion resistance is improved.

As shown in fig. 2, the braiding layer 12 is braided by a braiding machine, and the braiding layer 12 is a twill pattern and is made of polyester filaments. The woven layer 12 is formed by weaving warp threads 121 and weft threads 122, the weft threads 122 are horizontally and closely arranged, the warp threads 121 are pressed on the weft threads 122 or pass through the lower portion of the weft threads 122, the warp threads 121 press two weft threads 122 to pass through one weft thread 122, then press two weft threads 122 to pass through one weft thread 122, and the warp threads 121 are woven in a staggered manner.

The warp yarn 121 includes fine warp yarn 1211 and coarse warp yarn 1212, the fine warp yarn 1211 is interlaced with the coarse warp yarn 1212, the coarse warp yarn 1212 is surface treated before weaving, and a certain ratio exists between the number of fine warp yarns 1211 and the coarse warp yarn 1212. When the abrasion-resistant hose 1 is dragged on the ground, the warp threads 121 are worn out firstly, and as the thick warp threads 1212 protrude, only the thick warp threads 1212 contact the ground during the dragging, the thin warp threads 1211 are worn out after the thick warp threads 1212 are flattened, and the inner liner 11 is exposed after the thin warp threads 1211 are worn out.

Specifically, the number ratio of the fine warp threads 1211 to the coarse warp threads 1212 is 1:1, 2:1, 3:1, 4:1.

Further, the abrasion resistance is best when the ratio of the number of fine warp yarns 1211 to the number of coarse warp yarns 1212 is 1:1.

Specifically, the surface treatment of the coarse warp yarn 1212 prior to weaving may be performed using a wear-resistant aqueous pu coating, a silicon carbide coating, or a combination thereof.

Specifically, the fine warp 1211 is 2D polyester filament yarn, and the coarse warp 1212 is 10D polyester filament yarn.

Further, in the prior art, the warp yarns 121 of the woven layer 12 are all 2D polyester filaments, the warp yarns 121 of the woven layer 12 are modified from 1D or 2D polyester filaments with uniform original specifications to 2D polyester filaments and 10D polyester filaments, a certain number of ratios of the 2D polyester filaments to the 10D polyester filaments exist, and the 10D polyester filaments are subjected to surface treatment before weaving. When the abrasion-resistant hose 1 is dragged on the ground, warp yarns are worn out firstly, after 1D or 2D warp yarns with uniform original specifications of the weaving layer 12 are improved into 2D polyester filaments and 10D polyester filaments woven according to a certain number proportion, the 10D polyester filaments protrude out of the ground when being dragged, the 10D polyester filaments are contacted with the ground, the 2D polyester filaments are contacted with the ground after the 10D polyester filaments are ground flat, and the 2D polyester filaments are worn out to cause the damage of the inner liner 11, so that water leakage is caused.

Further, abrasion resistance test according to GB6246 and JIS test standard confirmed that the abrasion resistance of 10D polyester filaments was better.

Specifically, the woven layer 12 is woven by selecting the ratio of the number of the fine warp threads 1211 and the coarse warp threads 1212 according to the working condition or the cost.

In conclusion, the wear resistance of the hose is improved, the service life of the hose is prolonged, and the leakage risk during fluid transmission is reduced by changing the number proportion between the fine warp threads and the coarse warp threads and carrying out surface treatment on the coarse warp threads.
