Description
Technical field
The utility model relates to a kind of agricultural water-saving irrigation rig, and particularly improved drip irrigation pipe belongs to agricultural pouring technical field.
Background technology
Drip irrigation is that irrigation technology is watered in a kind of advanced person's water saving, it adopts a kind of special drip irrigation pipe to be laid in the farmland, and drip irrigation pipe is made by plastic flexible pipe, lays water dropper on the inwall of pipe equably, water dropper is provided with the labyrinth type turbulent flow passageway, and the terminal of passage is provided with towards the apopore of drip irrigation pipe outside.After being full of water in the drip irrigation pipe, water process turbulent flow passageway and the direct drip irrigation of apopore absorb plant to plant roots continuously fully, and its water consumption can also improve the output of crops effectively well below traditional broad irrigation mode.Facing under the situation of global shortage of water resources, promoting the use of drip irrigation technique and have great significance.So-called embedded drip irrigation pipe is meant that water dropper inlays the inwall in drip irrigation pipe.Water dropper in the drip irrigation pipe is the critical component that forms drip irrigation, only is provided with turbulent flow passageway and paddle hole on the water dropper that adopts usually, and the amount of dripping changes with the size of hydraulic pressure in the pipe.When hydraulic pressure was big, the amount of dripping was bigger, also reduced than hour amount of dripping and work as hydraulic pressure thereupon.Be accompanied by the prolongation of drip irrigation pipe, pressure in the pipe can be more and more littler, and therefore the laying length of common drip irrigation pipe is about 80-120 rice, and with the position difference of water dropper in drip irrigation, the amount of dripping also can change, and obviously such performance of dripping is very disadvantageous to crop management.
Summary of the invention
Technical problem to be solved in the utility model is: overcome the defective of above-mentioned prior art and provide a kind of and can automatically regulate the amount of dripping according to hydraulic pressure, keep the stable embedded compensation drip irrigation pipe of the amount of dripping.
The alleged problem of the utility model is solved by following technical scheme:
A kind of embedded compensation drip irrigation pipe, by body and the water dropper that evenly is arranged on the inboard wall of tube body form, water dropper is provided with the inlet opening, be provided with turbulent flow passageway and water chamber on the water dropper with on the bonding one side of tube wall, weeper on the corresponding tube wall of water chamber, its special feature is: described water dropper is provided with high pressure chest 2 and pressure stabilizing cavity 6, inlet opening 1 is communicated with high pressure chest, high pressure chest communicates by the water inlet of inlet opening 3 with turbulent flow passageway 4, the water side of turbulent flow passageway 4 communicates with pressure stabilizing cavity 6 by backwater hole 5, pressure stabilizing cavity 6 is communicated with exhalant canals 13 by apopore 7, and exhalant canal 13 is communicated with water chamber 8, and water chamber 8 communicates with weeper 12 on being located at drip irrigation pipe 14; Also be provided with compensation mechanism on the described water dropper, compensation mechanism is made of compensation rubber cushion 9, compensation boss 10, infiltration rill 11, and the compensation rubber cushion separates between high pressure chest and pressure stabilizing cavity and with both, and the infiltration rill is arranged in pressure stabilizing cavity and is communicated with apopore 7; The compensation boss is positioned at the upper surface setting of pressure stabilizing cavity bottom along apopore 7, and compensation rubber cushion 9 promptly is arranged on the top of compensation boss 10.
Above-mentioned embedded compensation drip irrigation pipe, described high pressure chest top is provided with gag 16, and inlet opening 1 promptly is arranged on the gag 16, gag and be located at and be interference fits between the gag hole on the water dropper body 15.
In order effectively to utilize the space, above-mentioned embedded compensation drip irrigation pipe, described turbulent flow passageway 4 is by three-back-shaped layout.
Above-mentioned embedded compensation drip irrigation pipe, described infiltration rill 11 is a bar ditch shape, its vertical section is a wedge shape.
Above-mentioned embedded compensation drip irrigation pipe, described inlet opening is provided with aperture plate 17.
The utility model has been set up compensation mechanism on the water dropper of drip irrigation pipe, it can automatically regulate the amount of dripping according to the hydraulic pressure in the drip irrigation pipe, makes the amount of dripping that is positioned at the drip irrigation pipe diverse location, is in the water dropper under the different hydraulic pressure equal substantially.The utility model can make the laying length of pipeline reach hundreds of rice, and can use in having the arable land of the gradient, and the amount of dripping is not subjected to the influence of ground location height, and its effect is much better than common drip irrigation pipe.

Fig. 6 is the cutaway view of gag.
Embodiment
Referring to Fig. 1～Fig. 4, water dropper 15 is bonded on the inwall of drip irrigation pipe 14.Turbulent flow passageway 4, water chamber 8 are arranged on and the contacted one side of tube wall.Along its short transverse, be provided with four shoulder holes that diameter successively decreases successively at the center of water dropper, the hole of diameter maximum is the gag hole, and minimum hole is an apopore 7.Compensation rubber cushion 9 is seated in two holes in the middle of being arranged in, and its edge rides on two steps between the hole.The space that is positioned at compensation rubber cushion top forms high pressure chest, and the space that is positioned at compensation rubber cushion bottom forms pressure stabilizing cavity, has water channel to be communicated with between two chambeies.
The operation principle of water dropper is as follows: the water in the drip irrigation pipe enters high pressure chest by inlet opening 1, gap between compensation rubber cushion and gag flows to voltage stabilizing inlet opening 3, and enter three-back-shaped turbulent flow passageway 4, the horizontal cross-section of turbulent flow passageway is indenting shape, and current are full of twists and turns therein, runs into very big resistance, after reducing hydraulic pressure, enter pressure stabilizing cavity 6 by return port 5, enter apopore 7 by pressure stabilizing cavity, enter water chamber 8 by apopore 7 through exhalant canal 13 again, and ooze outside the pipe by weeper 12.When the hydraulic pressure in the drip irrigation pipe is big, hydraulic pressure in the high pressure chest 2 is greater than the hydraulic pressure in the pressure stabilizing cavity 6, the compensation rubber cushion is being pressed under the effect of hydraulic pressure on the ring-type compensation boss 10 of pressure stabilizing cavity, the water that enters pressure stabilizing cavity 6 can only enter apopore 7 by infiltration rill 11, enter water chamber 8 by apopore 7 through exhalant canal 13 again, and ooze outside the pipe by weeper 12.Hydraulic pressure in drip irrigation pipe hour, the pressure of high pressure chest and pressure stabilizing cavity is after balance, the compensation rubber cushion separates slightly with the compensation boss, the water that enters pressure stabilizing cavity both can be from infiltration rill 11, also can enter apopore 7 from compensation boss and gap between the compensation rubber cushion, and outflow thereupon, flow to water chamber 8 through exhalant canal 13, ooze outside the pipe by weeper 12.This shows that by compensation rubber cushion 9, the compensation mechanism that compensation boss 10 and infiltration rill 11 constitute can be regulated the amount of dripping automatically according to the size of hydraulic pressure, no matter how pressure changes, and enters that the water yield of water chamber 8 always equates basically.
The effect of the aperture plate 17 on the inlet opening 1 is to be used for stoping the water dirt to enter in the water dropper.
