Abstract
The utility model relates to a pressure-resistant water hose, which comprises a hose wall, the hose wall is provided with a carcass, and an inner plastic film layer is combined with the inner surface of the carcass, and is bonded with the carcass through a bonding layer in between; and an outer plastic film layer is combined with the outer surface of the carcass, and is bonded with the carcass through another bonding layer in between. The bonding layer can be a coating layer. The water hose can effectively prevent the water seepage of the hose wall, thereby the service life of the water hose is prolonged, and in addition, the pressure-bearing capability of the water hose is enhanced as well.
Description
Technical field
The utility model belongs to a kind of delivery equipment, is specifically related to a kind of pressure-resistant water band.
Background technique
Water band be often used in agriculture irrigation, urban afforestation pouring, aquaculture or fields such as building industry, mine water delivery and since pressure-resistant water band with after can roll again, volume is little, in light weight, easy to use, thereby welcome by the user.Existing pressure-resistant water band generally all is provided with the braid that is interwoven with plastic flat fiber or yarn longitude and latitude, and braid has stronger tension anti crack performance, makes the water band can bear big hydraulic pressure; But,, make the impermeability of braid very poor so there is intensive hole in braid itself because braid is to adopt graticule to be interwoven.In order to prevent that moisture is from radially oozing out; usually also must spoon the leaching membrane layer of hot melt state on the surface of braid; can the hole filling of braid is stifled tight after leaching membrane layer condenses; but the thickness of leaching membrane layer is restricted; can not be too thick; otherwise the heat that the leaching membrane layer of hot melt state discharges can be scalded braid, braid tension anti crack performance is reduced, so the thickness of the leaching membrane layer of pressure-resistant water band can only be done very thinly.
Pressure-resistant water band in use, the leaching membrane layer that is positioned at outer surface inevitably can be often and coarse ground friction, putting, rolling up, drawing in the using process and very easily scratched, and the leaching membrane layer that is arranged in internal surface also can often be subjected to the silt friction of current inevitably, because the leaching membrane layer very thin thickness, so in use for some time, leaching membrane layer is quick-wearing very, make whole water band tube wall that seepage take place easily, shorten the working life of pressure-resistant water band.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of pressure-resistant water band is provided, and it can effectively prevent the tube wall infiltration.
Its purpose can realize by following scheme: this pressure-resistant water band comprises tube wall, and tube wall is provided with braid, and its main feature is that the inner face of braid is compounded with interior plastic film layers, is bonded together by an adhesive layer between interior plastic film layers and the braid; The outside of braid is compounded with outer plastic film layers, is bonded together by another adhesive layer between outer plastic film layers and the braid.
Be preferably, described adhesive layer is a leaching membrane layer.
Be more preferably, described braid is the plastic flat fiber braid.
Plastic film layers is a film layer in described, and described outer plastic film layers also is a film layer.
The utlity model has following advantage and effect:
1, the inner face and the outside of the utility model pressure-resistant water band tube wall all are compounded with plastic film layers, the thickness of plastic film layers can be unrestricted, its thickness can be several times of leaching membrane layer in the conventional construction, the wear-resisting property of plastic film layers is more much better than the leaching membrane layer of conventional construction, beyond plastic film layers can tolerate the friction on ground for a long time, interior plastic film layers can tolerate the silt friction in the current for a long time, effectively prevent leaktightness of wall of tubes, prolong the working life of pressure-resistant water band, the also corresponding in addition water band bearing capacity that improved improves its withstand voltage degree.
2, the leaching membrane layer of pressure-resistant water band has a plurality of effects in the utility model, and the first plays the effect of adhesive layer with braid and plastic film layers tight bond; It two is the holes that can fill up braid, plays the anti-effect of leaking of antiseepage; It three is skins that leaching membrane layer is positioned at braid, thus can also be as protective layer, so leaching membrane layer has the effect of one-object-many-purposes, demonstrates fully creativeness of the present utility model.
3, in the utility model pressure-resistant water band rational in infrastructure, production technology is simple, the anti-performance of leaking of antiseepage increases substantially
Description of drawings
Fig. 1 is the structural representation of a kind of specific embodiment of the utility model.
Embodiment
