Abstract
The utility model provides an antistatic high-pressure hose which comprises an inner hose layer and an outer layer. The antistatic high-pressure hose further comprises an enhancement layer, wherein the enhancement layer covers on the outside of the inner hose layer, the outer layer covers on the outside of the enhancement layer, and the enhancement layer is overlaid or mixed by a conducting layer and a fiber reinforcement layer. Therefore, not only is weight of the antistatic high-pressure hose lightened, but also static in high-pressure liquid can be removed by the conducting layer, and thus the antistatic high-pressure hose with light self weight is provided.
Description
Technical field
The utility model belongs to technical field of hoses, particularly the high pressure hose technical field.
Background technique
The high pressure hose that is applied to now conveying high-pressure liquid need to be got rid of the static of the generation in the course of conveying, with the quality (such as high-pressure spray-painted spraying industry) that improves operating security and product.This type of high pressure hose structure has two kinds: a kind of is that inner tube layer+steel wire reinforcement layer skeleton+skin forms, and another kind is that inner tube layer+fiber-reinforced layer skeleton+skin forms.The former can utilize the static in the steel wire reinforcement framework layer eliminating highly pressurised liquid, but because the weight of the flexible pipe of itself is heavier, causes the user to increase working strength, when especially needing to carry at a distance, causes especially this puzzlement; Although the very light in weight of latter's flexible pipe own is because all manufactured materialss are insulating material, so have no idea to get rid of the static that produces in the liquid course of conveying by flexible pipe itself.
Summary of the invention
The utility model main purpose is in order to address the above problem, and a kind of antistatic high pressure hose that not only can destatic but also can reduce by busbar the flexible pipe deadweight is provided.
In order to achieve the above object, the technological scheme that the utility model provides is: a kind of antistatic high pressure hose, comprise inner tube layer and skin, and also comprise enhancement layer; Enhanced layer packets overlays on the inner tube layer outside; Skin is coated on the outside of enhancement layer;
Enhancement layer is formed by fiber-reinforced layer and conductive layer stack;
Fiber-reinforced layer is at least one deck; Conductive layer is at least one deck; Conductive layer places between layer of fibers and the skin, and perhaps conductive layer is as between the two-layer fiber-reinforced layer;
Enhancement layer is mixed by fiber-reinforced layer and conductive layer;
Fiber-reinforced layer is formed by fiber or conductive fiber braiding; Conductive layer is conductive material.
The utility model namely can reduce the weight of flexible pipe self owing to being superposeed by conductive layer and fiber-reinforced layer or mixing, and can also utilize in use the static in the conductive layer eliminating highly pressurised liquid.
Description of drawings:
Fig. 1 is the first embodiment's of the present utility model structural representation;
Fig. 2 is another kind of embodiment's of the present utility model structural representation.
Embodiment:
Embodiment 1:
As shown in Figure 1: a kind of antistatic high pressure hose, comprise inner tube layer 1 and skin 2, also comprise the enhancement layer that is formed by stacking by fiber-reinforced layer 3 and conductive layer 4; Enhanced layer packets overlays on inner tube layer 1 outside; Outer 2 are coated on the outside of enhancement layer.Wherein fiber-reinforced layer 3 is two-layer; Conductive layer 4 is one deck; Conductive layer 4 places between the two-layer fiber-reinforced layer 3; And fiber-reinforced layer 3 is formed by fibrage; Conductive layer 4 is conductive material.
During making, plastic extruder is extruded inner tube layer 1; Use fibrage first layer fiber-reinforced layer 3 on the knitting machine; Extruder is at the enhancement layer conductive plastics of 3 outer cladding last layers or rubber layer 4; Use fibrage second layer fiber-reinforced layer 3 on the knitting machine; Coating outer 2 with extruder at last gets final product.
Certainly, enhancement layer also can be formed by stacking by one deck, two-layer or more multi-layered fiber-reinforced layer 3 and two-layer or more multi-layered conductive layer 4.
Embodiment 2:
As shown in Figure 2: present embodiment and embodiment's 1 difference is: enhancement layer is to be mixed by fiber 3 and conductive fiber 4.
During making, with plastic extruder inner tube layer 1 is extruded; Again at the knitting machine fibrage first layer enhancement layer that is mixed with conductive fiber or conductive material; Then at the knitting machine fibrage second layer enhancement layer that is mixed with conductive fiber or conductive material; Coating outer 2 with extruder at last gets final product.
Certainly, in embodiment's 2 similar high pressure hoses therewith, also can have the 3rd, the 4th even the more multi-layered enhancement layer that are mixed by fiber-reinforced layer 3 and conductive fiber 4.The utility model namely can reduce the weight of flexible pipe self owing to being superposeed by conductive layer 4 and fiber-reinforced layer 3 or mixing, and can also utilize in use the static in the conductive layer eliminating highly pressurised liquid.Thereby provide a kind of antistatic high pressure hose from heavy and light.
