Embodiment

As shown in Figure 1, a kind of bidirectional flow arc irrigate band comprises arc Flexible water pipe 2, and arc Flexible water pipe 2 is the flat Flexible water pipe of 3/4 circumference, and its diameter is 70～100cm.The centre position of the outer side edges wall of arc Flexible water pipe 2 is provided with Flexible water pipe water inlet 1; Evenly have four runner delivery ports 7 on the inner side edge wall of arc Flexible water pipe 2, be provided with the bidirectional flow runner at arc Flexible water pipe 2 inner chambers and each runner delivery port 7 corresponding positions.

These four bidirectional flow runners include two runner limit walls 3, divide water spare 5 and water deflector 6.In each bidirectional flow runner; Two runner limit walls 3 are symmetrically distributed in the both sides of corresponding runner delivery port 7; And the rear end of two runner limit walls 3 and up and down two ends all be fixedly connected with the inwall of arc Flexible water pipe 2, the front interval setting of two runner limit walls 3 also forms runner water inlet 4.Like this, each bidirectional flow runner inside forms the space of relative closure, and communicates with arc Flexible water pipe 2 inner flow passages through runner water inlet 4.Divide water spare 5 and water deflector 6 coaxial being arranged between two runner limit walls 3, divide water spare 5 to be positioned at the position near runner water inlet 4, water deflector 6 is positioned at the position near runner delivery port 7.Divide water spare 5 to form, and between two branch water plates, form water hole by one-tenth splayed symmetry and two branch water plates spaced apart.Water deflector 6 is a V font plate.Divide the two ends up and down of water spare 5 and water deflector 6 all to be fixedly connected with the inwall of arc Flexible water pipe 2, all left aquaporin between the limit wing of branch water spare 5 and water deflector 6 and the corresponding runner limit wall 3, the direction of dehiscing of branch water spare 5 and water deflector 6 is towards runner water inlet 4.

Dividing the subtended angle scope of water spare 4 and water deflector 5 is 40 °～120 °.The width of runner water inlet 4 and runner delivery port 7 is 1.0～1.8mm, and each width of crossing aquaporin is 0.8～1.6mm, and the width of water hole is 0.8～1.6mm.

Arc Flexible water pipe 2 can stitch 8 heat seals through the limit by polythene material and form, and runner limit wall 3, branch water spare 5 and water deflector 6 are used polythene materials usually, and fix with 2 heat seals of arc Flexible water pipe.

The utility model bidirectional flow arc irrigate band is applicable to the trees irrigation.In use, arc Flexible water pipe 2 is laid around trees, made runner delivery port 7 on the arc Flexible water pipe 2 towards trees, Flexible water pipe water inlet 1 is connected with drip irrigation pipe gets final product again.The utility model working pressure range is 0.05～0.30MPa, and each bidirectional flow runner flow is 4～8L/h, and the runner spacing is 30～80cm.

The energy dissipating principle of the utility model is: during drip irrigation system work, at first drip irrigation system pressure water stream gets into arc Flexible water pipe 2 by drip irrigation pipe from Flexible water pipe water inlet 1; In arc Flexible water pipe 2 inside, pressure water stream gets into corresponding bidirectional flow runner by each runner water inlet 2; Inner at each bidirectional flow runner, at first be divided into three strands of current through minute water spare 5, wherein at inboard one current of minute water spare 5 in flow process; Because the cross-section of river shrinks gradually, eliminate portion of energy, this strand current are eliminated portion of energy again when water hole thereafter; After this strand current pass through water hole; Under water deflector 6 effects, this strand current change the flow direction, form two strands of reverse flows; Meanwhile, meet,, eliminate pressure water stream excess energy through strong blending through two strands of forward current and the above-mentioned two strands of reverse flows of crossing aquaporin between minute water spare 5 dual-side wings and the runner limit wall 3; Then two strands of current after the blending are through the excessively aquaporin of water deflector 6 between both sides outer wing and runner limit wall 3, through spreading further energy dissipating, after corresponding runner delivery port 7 splashes near the soil layer of tree root.

The utility model is through forming bimodal current, and again through the blending energy dissipating, the usefulness effect of easing stress is good on the one hand, has improved the uniformity of effluenting, and on the other hand, because forward and reverse current blending is strong in the bidirectional flow runner, has also improved its anti-clogging; And it is little to have a manufacture deviation, and production cost is low and be convenient to characteristics such as installation.
