Description
Technical field
The utility model belongs to a kind of delivery equipment, and in particular to a kind of Compound Water band being combined by multilayer material.
Background technology
Compound Water band can be applied to the water delivery in the fields such as field irrigation, construction industry, mining industry water delivery, aquaculture.It is compound
Water band generally comprises useful braiding layer and lining plastic film layer, and braiding layer is interwoven by plastic flat fiber or yarn longitude and latitude, have compared with
Strong tension anti crack performance, enables water band to bear larger hydraulic pressure；But since braiding layer is in itself there are intensive hole, in order to prevent
Moisture is oozed out from radial direction, thus must also at least on the inside of braiding layer is compound again lining plastic film layer, it is multiple outside braiding layer
Conjunction has outer protection plastic film layer.
The manufacturing process of conventional composite water band is usually first to answer braiding layer 2 and lining plastic film layer 1, outer protection plastic film layer 3
It is combined and becomes multiple tube wall blank, then plane compound tube wall blank bending and head and the tail bonding is become into pipe
Shape, the tubulose tube wall blank after head and the tail overlap are known as tube wall, and shown in Fig. 1, tube wall includes lap segment and non-overlapping section 43, lap segment
Including outer lap segment 42 and inside lap section 41, wherein being known as " outer lap segment " positioned at outer layer after overlap joint, it is located at internal layer after overlap joint
Be known as " inside lap section ".
Conventional composite water band has the following disadvantages：Since Compound Water band has higher hydraulic pressure in use, and interior take
The braiding layer for connecing the edge position of section is directly contacted with current, is not an organic whole in itself plus braiding layer, but by passing through
Line and weft are interwoven, there are gap between every two adjacent warps of braiding layer, between the every two adjacent wefts of braiding layer
There are gap, braiding layer rugged surface is not with Plastic film surface since bonding is fine and close similarly there are gap, and above-mentioned gap is all
Infiltration path is likely to form, so moisture can penetrate into braiding layer by the edge of inside lap section, and by passing through braiding layer
Above-mentioned infiltration path along the circumferential gradually exudation of tube wall, finally reach the edge of outer lap segment, as shown by the arrows in figure 2, and
Constantly oozed out in the form of droplet outside Compound Water band, so can not only cause leak, and can gradually destroy lining plastic film layer with
The bonding degree of braiding layer, makes lining plastic film layer be easily peeled off with braiding layer, shortens the service life of Compound Water band.
In order to solve this problem, applicant discloses a solution in the patent document of CN201448528U,
The end of inside lap section forms the extension section 10 of interior plastic film, and the extension section 10 of the lining plastic film layer of the inside lap section with taking outside
The lining plastic film layer for connecing section is bonded together, as shown in Figure 3.In this way, make the braiding layer at the edge line position of inside lap section complete
Isolate with current in tube chamber, prevent current and gradually circumferentially oozed out along tube wall by braiding layer, avoid leak, and prevent because of infiltration and
Cause to be easily peeled off between each layer of tube wall, extend the service life of water band.
However, applicant has found in further exploration and use：Due to the extension section 10 of lining plastic film layer and liner
1 main body of plastic film layer is the material of same composite bed, so both thickness must can only be identical, and liner plastic film layer main body portion
The outside of position is coated with braiding layer, thus in order to save cost, the thickness of lining plastic film layer is commonly designed relatively thin, therefore accordingly
The extension section of lining plastic film layer be typically not enough to be formed impervious effect fully effectively anti-enough；If lining plastic is increased for this
The thickness of film layer extension section, and the thickness of lining plastic film layer entirety can be made synchronously to improve, cause to waste and cost raises up.
Utility model content
A kind of Compound Water band is provided the purpose of the utility model is to overcome disadvantages mentioned above, its overlapping part edge department
Potential energy is effectively impervious, and need not increase the thickness of lining plastic film layer.
Its purpose can be realized by following scheme：A kind of Compound Water band, including by lining plastic film layer, braiding layer, outer protection
The tube wall that plastic film layer is combined, tube wall head and the tail overlap to form inside lap section and outer lap segment in the circumferential, its main feature
It is, the width of lining plastic film layer is equal to the width of braiding layer, and the width of outer protection plastic film layer is equal to the width of braiding layer；Inside
The inner side at lap segment edge is also adhesive with interior joint strip, and the width of interior joint strip is less than the width of inside lap section, and the thickness of interior joint strip is big
In the thickness of lining plastic film layer；Outer joint strip is also adhesive with the outside at outer lap segment edge, the width of outer joint strip is less than outer overlap joint
The width of section, the thickness of outer joint strip are more than the thickness of outer protection plastic film layer；The length of interior joint strip and outer joint strip is to along Compound Water band
Grow to extension.
In present specification, the width at some so-called position, refers to the component along circumferentially extending of the Compound Water with tube wall
Size.
The utility model has the following advantages and effect：
First, the edge position of interior joint strip covering inside lap section, prevents moisture by the edge position of inside lap section and then edge
Braiding layer gradually outwards to ooze out, avoid leak, and prevent because infiltration and caused by the circumferentially overlapping position of tube wall it is easily peelable, extend multiple
The service life of Heshui band.Similar, outer joint strip covers the edge position of outer lap segment, and can also erect prevents moisture from oozing out together
Defence line.
2nd, interior joint strip, outer joint strip, the thickness of lining plastic film layer three are unrelated, can respective independent design thickness, and
Interior joint strip, the width of outer joint strip are smaller, thus are conducive to increase interior joint strip, the thickness of outer joint strip, it is ensured that its antiseepage effect, at the same time
Cost will not be increased substantially again.
