Abstract

The utility model discloses a thin wall micro-irrigation flexible pipe with single side pores, which comprises a thin wall plastic pipe body with excurrent pores, wherein the excurrent pores are evenly distributed on the pipe wall above the plane of the horizontal pipe diameter of the pipe body along the axial direction of the pipe body. Because the excurrent pores of the pipe body of the utility model are far away from the ground, water in the pipe spouts out of the excurrent pores slantingways and upwards. Thus, silt both on the ground and in the pipe can not block the excurrent pores, and the situation that water output is large or small in a plurality of excurrent pores can not appear. Thus, the utility model has the advantages of good anti-blocking performance and even irrigation of the fields, and overland runoff is not easy to form when the fields are irrigated.

Description

Single face aperture thin-walled slight irrigation flexible pipe

Technical field

The improvement of the thin walled hose of using when the utility model belongs to the irrigated farmland, particularly single face aperture thin-walled slight irrigation flexible pipe.

Background technology

Normal pressure flexible pipe irrigation system under the film that uses in the farmland operation, all be to adopt plastic thin wall flexible pipe with two-sided through hole, promptly on the upper and lower both sides tube wall on the plane, horizontal caliber place of flexible pipe apopore is being set respectively, apopore axially is distributed on the tube wall along flexible pipe.When this plastic thin wall flexible pipe water flowing, flow out the apopore of water from the tube wall of upper and lower both sides, water yield is big, forms surface runoff easily, in addition, in silt enters flexible pipe, apopore on second tube wall of flexible pipe very easily stops up, and water yield is reduced, and the apopore water yield that has like this is big, the apopore water yield that has is little, causes the uneven phenomenon of irrigating the fields easily.

The utility model content

The purpose of this utility model is to provide a kind of single face aperture thin-walled slight irrigation flexible pipe, and when irrigating the fields with it, not only apopore is difficult for stopping up, and anti-blocking performance is good, irrigate the fields evenly, and manufacturing is easier, and production cost is cheaper.

The purpose of this utility model is achieved in that a kind of single face aperture thin-walled slight irrigation flexible pipe, comprises the thin-walled plastic body with apopore, and said apopore is arranged on along body axial uniform on the tube wall of top, horizontal caliber plane of body.

Because the position at the apopore place on the utility model body is away from ground, water in the pipe is from upwards ejection of apopore medium dip, like this, be that ground or the interior silt of pipe can not stop up apopore, the little situation of apopore water yield that the apopore water yield that more can not have has greatly, not only anti-blocking performance is good, and irrigates the fields evenly, is difficult for forming rainwash when irrigating the fields.The utility model is banded with the body press-stretched when punching, evenly punching in a side of body axis gets final product, and it is easier to make, and uses hardly existing production line is done excessive change, can produce, and production cost is cheaper.

Embodiment

A kind of single face aperture thin-walled slight irrigation flexible pipe as Fig. 1, Fig. 2, shown in Figure 3, comprises the thin-walled plastic body 2 with apopore 1, and said apopore 1 is arranged on along body 2 axial uniform on the tube wall of top, horizontal caliber plane of body 2.As shown in Figure 2, apopore 1 is the double hole along the axis symmetry of body 2.Apopore 1 be shaped as circular port, slotted eye, square opening or tri-angle-holed.As shown in Figure 3, when the utility model is worked at water-filling, because the position at apopore 1 place on the body 2 is away from ground, water in the pipe like this, is that the silt in ground or the pipe can not stop up apopore 1 from upwards ejection of apopore 1 medium dip, the little situation of apopore 1 water yield that apopore 1 water yield that more can not have has greatly, not only anti-blocking performance is good, and irrigates the fields evenly, is difficult for forming rainwash when irrigating the fields.The utility model is banded with body 2 press-stretcheds when punching, evenly punching in a side of body 2 axis gets final product, and it is easier to make, and uses hardly existing production line is done excessive change, can produce, and production cost is cheaper.
