Abstract
The utility model relates to a sand blasting glue tube which comprises a tube body. The tube body comprises an inner glue layer, a strengthening layer and an outer glue layer, wherein the inner glue layer, the strengthening layer and the outer glue layer are sequentially arranged from inside to outside, the strengthening layer comprises an inner layer high-strength glue dipping polyester cord thread, a middle glue sheet layer and an outer layer high-strength glue dipping polyester cord thread, and the inner layer high-strength glue dipping polyester cord thread, the middle glue sheet layer and the outer layer high-strength glue dipping polyester cord thread are sequentially arranged from inside to outside. The inner layer high-strength glue dipping polyester cord thread is wound on the outer wall of the inner glue layer, the outer layer high-strength glue dipping polyester cord thread is wound on the outer wall of the middle glue sheet layer, a steel wire is wound on the outer wall of the middle glue sheet layer, and the winding direction of the steel wire is the same as the winding direction of the inner layer high-strength glue dipping polyester cord thread. The sand blasting glue tube can effectively improve pressure-bearing performance of a tube body, straight performance of the tube body and bending resistance performance of the tube body, solve the problem of partial sinking, caused by bending in a using process, of the tube body, solve the problem of partial abrasion quickening or explosion caused by the fact that flow of mortar is blocked, and greatly improve safety performance. The service life of the sand blasting glue tube is prolonged.
Description
Technical field
The utility model relates to a kind of sand blast hose, and particularly a kind of cotton thread with the steel wire helix twines sand blast hose.
Background technique
Sand blast hose is as media such as a kind of transporting water mud, rust cleaning sand, it is of many uses for extraordinary sebific duct about working pressure 0.5MPa, traditional sand blast hose adopts multilayer (5-7 layer) cord fabric as enhancement layer, and the body unit weight is big, and heavy body uses for construction and brings very big inconvenience; If but the number of plies of reduction canvas, the bearing capacity of body descends, and explosion easily again produces potential safety hazard in the using process.
The model utility content
The purpose of this utility model is to provide a kind of the deficiencies in the prior art that remedy, use bearing capacity height, bending radius little, light, safe, can guarantee that sand blast hose is difficult for explosion, the sand blast hose of the new structure of potential safety hazard is stopped in convenient carrying and using simultaneously.
To achieve these goals, the utility model has adopted following technological scheme:
A kind of sand blast hose, comprise body, described body comprises inner glue layer, enhancement layer and the outer glue-line that sets gradually from the inside to the outside, described enhancement layer comprises internal layer high strength impregnation polyester cord, outer high strength impregnation polyester cord and middle glue film layers, the glue film layers places between described internal layer high strength impregnation polyester cord and the outer high strength impregnation polyester cord in described, described internal layer high strength impregnation polyester cord is wrapped on the outer wall of described inner glue layer, and described outer high strength impregnation polyester cord is wrapped on the outer wall of described middle glue film layers.
Further, described internal layer high strength impregnation polyester cord, outer high strength impregnation polyester cord twine with 50 ° of-57 ° of angles that axially are of body respectively in the opposite direction.
Further, be wound with a steel wire on the outer wall of described middle glue film layers, the winding direction of this steel wire is consistent with the winding direction of internal layer high strength impregnation polyester cord.
Further, described steel wire and body axial line are 20 °-45.
Further, described gauge of wire is 1.6mm-2.4mm.
The utility model improves the pressure-bearing property performance of body by the high-strength polyester cord, improve very property and the resistance to bend(ing) energy of body by steel wire, solving body in use causes local sunken because of bending, thereby the mortar constricted flow produces concentrated wear acceleration or explosion problem, has greatly increased sand blast hose working life and Safety performance.
Description of drawings
Fig. 1 is cross-sectional schematic of the present utility model.
Embodiment
Now by reference to the accompanying drawings, describe the utility model in detail.
With reference to accompanying drawing 1, a kind of sand blast hose, comprise body, body comprises inner glue layer 11, enhancement layer and the outer glue-line 12 that sets gradually from the inside to the outside, and wherein, inner glue layer 11 is innermost layers of sand blast hose, directly contact fed sheet of a media, play abrasionproof, leakproof effect, the outermost surface of body is ageing-resistant outer glue-line, plays protection body enhancement layer; Enhancement layer comprises internal layer high strength impregnation polyester cord 131, outer high strength impregnation polyester cord 132 and middle glue film layers 133, middle glue film layers 133 places between internal layer high strength impregnation polyester cord 131 and the outer high strength impregnation polyester cord 132, internal layer high strength impregnation polyester cord 131 is wrapped on the outer wall of inner glue layer 11, and outer high strength impregnation polyester cord 132 is wrapped on the outer wall of middle glue film layers 133.
Internal layer high strength impregnation polyester cord 131, outer high strength impregnation polyester cord 132 twine with 50 ° of-57 ° of angles that axially are of body respectively in the opposite direction, play the effect that improves the body load performance.
In steel wire 134 that to be wound with a diameter on the outer wall of glue film layers 133 be 1.6mm-2.4mm, the winding direction of this steel wire is consistent with the winding direction of internal layer high strength impregnation polyester cord, and be 20 °-45 with the body axial line, middle glue film layers is to high strength impregnation polyester cord layer and steel wire three's the adhesive effect that plays, and steel wire plays the counter-bending and withstand voltage flat effect that improves body.
Above-described the utility model mode of execution does not constitute the restriction to the utility model protection domain.Any modification of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the claim protection domain of the present utility model.
