Abstract
The invention relates to a balanced runner labyrinth type drip irrigation tape. The proximal end of one end of a labyrinth runner of the drip irrigation tape is provided with a water outlet, the proximal end of the other end of the labyrinth runner is provided with another water outlet, and the labyrinth runner positioned between the two water outlets is provided with a water inlet. When water enters in the labyrinth runner from the water inlet, the water is shunted to left and right through the labyrinth runner so as to be beneficial to dispersing the pressure of a water head; and when one ofthe water outlets of a section of the balanced runner labyrinth type drip irrigation tape flows no water due to the blockage of the labyrinth runner, the water outlet positioned on an adjacent section of the balanced runner labyrinth type drip irrigation tape still normally works so as to be beneficial to enhancing the uniformity of water irrigation, thus the problem that the water can not be delivered to the roots of crops due to the blockage by one-way water outflow is solved.
Description
Technical field
The present invention relates to a kind of micro-irrigation emitter, particularly a kind of balanced runner labyrinth type drip irrigation tape.
Background technology
Along with the development of water-saving agriculture engineering, the quality of pouring water is had higher requirement, also have higher requirement for the micro-irrigation emitter drip irrigation zone.Labyrinth type drip irrigation tape commonly used at present, its labyrinth flow-path is distributed in manages on last or the Guan Yi, its structure is: the drip irrigation zone is provided with the plurality of sections labyrinth flow-path, every section runner two ends are provided with water inlet, delivery port, because of delivery port is positioned at the end in labyrinth, when stopping to pour water, delivery port produces negative pressure because of release, adsorb earth easily, and delivery port is blocked.For addressing the above problem, delivery port moved to certain distance from the termination, but because of being unidirectional water inlet, unidirectional water outlet is unfavorable for the decomposition of hydraulic pressure, can cause one section labyrinth flow-path and stop up after obstruction of delivery port, system is broken down, delivery port can't be transported to water the root of crop, causes to pour water inhomogeneously, influences the growth of crop.
Summary of the invention
The objective of the invention is to solve easy obstruction that existing drip irrigation zone exists, pour water inhomogeneous, be unfavorable for the problem that pressure decomposes, and then a kind of decomposition that helps hydraulic pressure in the runner be provided, be difficult for stopping up, reliability is high and the uniform balanced runner labyrinth type drip irrigation tape of pouring water.
A kind of balanced runner labyrinth type drip irrigation tape, the proximal end of labyrinth flow-path one end of drip irrigation zone is provided with a delivery port, and the other end proximal end of its labyrinth flow-path is provided with another delivery port, and the labyrinth flow-path place between two delivery ports is provided with water inlet.
Above-mentioned water inlet and two delivery ports are symmetrical arranged about the center line of labyrinth flow-path respectively, make hydraulic pressure keep balance in labyrinth flow-path, help the decomposition of hydraulic pressure in the runner and pour water even.
Above-mentioned water inlet is at least two runners and constitutes, and is used for the amount of water required to two delivery port supply crops.
Above-mentioned delivery port is made of two adjacent fluid channels at least, can improve uniformity of irrigation water appilcation.
Above-mentioned water inlet runner number is the twice of one-sided delivery port runner number, supplies water fully to delivery port.
Above-mentioned labyrinth flow-path is located on the Guan Yi, is convenient to processing.
Above-mentioned delivery port is positioned at 1/8th places of labyrinth flow-path length overall, has both played the effect of water storage, has kept the effective length of labyrinth flow-path again, is beneficial to pour water evenly.
The present invention sets up a delivery port on each section labyrinth flow-path, and then forms two delivery ports and make water inlet between them, when the water inlet of water from different sections enters the labyrinth flow-path, shunts to the left and right by labyrinth flow-path, helps decomposing head pressure.When certain delivery port of one section balanced runner labyrinth type drip irrigation tape stops up not water outlet because of labyrinth flow-path, or because impurity stops up labyrinth flow-path during not water outlet, adjacent delivery port is also in operate as normal, thereby solved unidirectional water outlet can't be transported to water crop root because of obstruction problem, reduce fault, improve the reliability of system, reduced maintenance cost.Simultaneously, help improving uniformity of irrigation water appilcation.The present invention is simple in structure, is easy to user's grasp and use, is convenient to promote.Advantage of the present invention specifically is as follows:
1, the length of labyrinth flow-path can be adjusted spacing according to the growth spacing in the rows of crop.
2, production technology is simpler, and the labyrinth flow-path end can store a certain amount of water, can play cushioning effect, effectively prevents to have improved performance of anti-blockage because of negative-pressure adsorption earth stops up delivery port.
3, two adjacent delivery ports have improved uniformity of irrigation water appilcation.
4, water inlet is located at the centre of labyrinth flow-path, helps decomposing head pressure.
5, labyrinth flow-path is provided with two delivery ports, can reduce irrigation period, reduces the cost of system header.
Description of drawings
Fig. 1 is existing labyrinth type drip irrigation tape schematic diagram.
Fig. 2 is the schematic diagram of the embodiment of the invention.
Fig. 3 uses the schematic layout pattern that existing labyrinth type drip irrigation tape is poured water.
Fig. 4 uses the schematic layout pattern that the present invention pours water.
Among Fig. 1-4,1 is water inlet, and 2 is labyrinth flow-path, and 3 is the drip irrigation zone, and 4 is delivery port, and 5 is Guan Yi.
The specific embodiment
As shown in Figure 2, the pipe wing 5 of the drip irrigation zone 3 of present embodiment is provided with labyrinth flow-path 2, the proximal end at labyrinth flow-path two ends respectively is provided with a delivery port 4, delivery port is positioned at 1/8th places of labyrinth flow-path length overall, delivery port is made of three adjacent fluid channels, labyrinth flow-path place between two delivery ports is provided with water inlet 1, and water inlet is that six runners constitute; Be that water inlet runner number is the twice of one-sided delivery port runner number, water inlet and two delivery ports are symmetrical arranged about the center line of labyrinth flow-path respectively.
Delivery port can be for a plurality of in the foregoing description, and as four, six etc., the delivery port runner can constitute by two, four, nine etc.
Operation principle:
With reference to accompanying drawing 1-4, when current through the drip irrigation zone, from the water inlets of different sections water is transported to labyrinth flow-path to both sides, by labyrinth flow-path water is delivered to delivery port and end end; By delivery port water is delivered to crop root.And two end ends of labyrinth flow-path can store a certain amount of water, are used to prevent because of negative-pressure adsorption earth stops up delivery port, improve performance of anti-blockage.
The present invention compares with existing product, and in concrete the use, a general strain crop is by adjacent two water outlets Mouth is its water supply (seeing Fig. 4), can shorten like this irrigation period, reduces and stops up the crop lack of water that causes, two Individual adjacent delivery port can improve uniformity of irrigation water appilcation, reduces labour intensity and energy consumption, reduces maintenance cost. Wherein one section balanced runner labyrinth type drip irrigation tape delivery port stops up, and the another one delivery port still can be tieed up Hold the work of this section balanced runner labyrinth type drip irrigation tape.
