Description

The compensation irrigator of a kind of big flow pressure
Technical field
The utility model belongs to agricultural economy woods irrigation technique field, arid and semi-arid area, relates to a kind of irrigator, particularly a kind of compensation irrigator of big flow pressure that is applicable to that the mountain region economic forest is irrigated.
Background technology
The mountain region economic forest is irrigated and has two problems at present: the one, because the mountain region discrepancy in elevation is bigger, drip irrigation system is difficult to guarantee uniformity of irrigation water appilcation; The 2nd, irrigator (water dropper) flow is less relatively, and generally at 2 ~ 8L/h, because the each irrigation requirement of economic forest is big, the irrigator of flow can not satisfy it like this needs the water requirement; The 3rd, irrigation system cost height, pressure-compensated irrigator complex structure in the market, the cost height has increased the deployment cost of whole irrigation system, is not easy to the popularization of water-saving irrigation cause.Therefore develop a kind of compensation irrigator of big flow pressure that is applicable to that the mountain region economic forest is irrigated and become problem demanding prompt solution.
201010156199.9) and a kind of adjustable-pressure fountain root irrigation machine (application number: 201010156210.1) a kind of screw-type fountain root irrigation machine (application number:, the irrigator labyrinth flow-path has been carried out optimal design, hydraulic performance is good, but does not have pressure compensation; 201110414698.2) and the big compensation irrigator of flow pressure (application number: 201210006948.9) labyrinth path is combined with the pressure-compensated structure a kind of buried pressure fountain root irrigation machine (application number:, have big flow and pressure compensation performance, irrigate requirement though meet economic forest, but structure relative complex, it is complicated to make mould, and manufacturing deviation is bigger, and cost is also higher.
Summary of the invention
Problems and shortcomings at above-mentioned prior art existence, the purpose of this utility model is to provide a kind of uniformity of irrigation water appilcation height, strong good, cheap, the simple in structure compensation irrigator of big flow pressure of performance of anti-blockage, is specially adapted to the big crop irrigations of water requirement such as mountain region economic forest.
To achieve these goals, the utility model is taked following technical solution:
The compensation irrigator of a kind of big flow pressure is made up of cavity, pressure compensation pad and pedestal three parts, and described cavity and pedestal fasten by draw-in groove, and described pressure-compensated pad is positioned on the staircase structural model of base interior; Described cavity upper end is provided with irrigator water inlet and screen pack; Described pedestal bottom is provided with delivery port; Described base interior bottom surface arranges secondary channels; Described base outer wall is provided with the circulation chamber; One end in described circulation chamber is communicated with circulation chamber water inlet on being located at pedestal, and its other end is connected with circulation chamber delivery port on being located at pedestal.
Described circulation chamber water inlet is positioned at the top of pressure-compensated pad, and described circulation chamber delivery port is positioned at the below of pressure-compensated pad.
Described pressure compensation pad is a rubber-like disk, and disk is step, and the staircase structural model in its size and the pedestal matches.
The inside and outside footpath of described irrigator water inlet and length thereof match with standard component, so that being connected of irrigator and hollow billet.
Described irrigator water inlet is provided with screen pack, is used for strengthening the anti-blockage capability of irrigator.
The secondary channels of described base interior is used for guaranteeing the minimum discharge of irrigator.
The compensation irrigator operation principle of big flow pressure of the present utility model is:
Current enter the water dropper cavity from the water inlet of cavity, and the pad upper surface of flowing through enters the circulation chamber, arrive the irrigator delivery port of pad bottom behind the outflow circulation chamber, and along with the continuous variation of pressure, the pad distortion changes discharge section area, thereby regulates the water dropper flow.Pressure change, distortion in various degree takes place in pad, changes irrigator delivery port discharge section area, thereby plays the effect of regulating flow, and this state is called adjustment state.Before entering the pressure compensation interval, the basic base bottom fully of pressure compensation pad, cavity volume is bigger, and irrigator delivery port discharge section area also becomes greatly, at this moment is from the flushing state.
The compensation irrigator of big flow pressure of the present utility model, evidence through the applicant, the pressure compensation interval is 80kPa-400kPa, flow is 11.3L/h, the fluidised form index is 0.0545, and pressure compensation is functional, uniformity of irrigation water appilcation is high, and the irrigator flow is big, performance of anti-blockage good, cost is low, has satisfied the requirement that economic forest is irrigated.
Description of drawings
Fig. 1 is the overall structure profile of the compensation irrigator of big flow pressure.
Fig. 2 is the compensation irrigator cavity body structure of big flow pressure schematic diagram.
Fig. 3 is the compensation irrigator base construction of big flow pressure schematic diagram.
Below in conjunction with the drawings and specific embodiments, the present invention is further described in detail.
Embodiment
Referring to Fig. 1, present embodiment provides the compensation irrigator of a kind of big flow pressure, the compensation irrigator of the big flow pressure of this kind, formed by cavity 1, pressure compensation pad 2 and pedestal 3 three parts, described cavity 1 fastens by draw-in groove with pedestal 3, and described pressure-compensated pad 2 is positioned on the staircase structural model 8 of pedestal 3 inside.
Fig. 2 has provided the compensation irrigator cavity body structure of the big flow pressure of the utility model schematic diagram, and cavity 1 upper end is provided with irrigator water inlet 4 and screen pack 5; Described pedestal 3 bottoms are provided with delivery port 9.
Fig. 3 has provided the compensation irrigator base construction of the big flow pressure of the utility model schematic diagram, and pedestal 3 outer walls are provided with circulation chamber 10; One end in described circulation chamber 10 is communicated with circulation chamber water inlet 11 on being located at pedestal 3, and its other end links to each other with circulation chamber delivery port 12 on being located at pedestal 3; Circulation chamber water inlet 11 is positioned at the top of pressure-compensated pad 2, and described circulation chamber delivery port 12 is positioned at the below of pressure-compensated pad 2.
The secondary channels 7 of described pedestal 3 bottoms when pad is pressed to the irrigator delivery port fully, guarantees the minimum discharge of irrigator, uninterrupted water supply to plant.
The inside and outside footpath of described irrigator water inlet and Design of length thereof become to match with standard component, so that be connected with hollow billet.
Described pressure-compensated pad is staircase structural model, and the step dimension of pad and the staircase structural model of base interior match, and guarantees that pad is fixing between cavity and pedestal.Under different operating pressures, corresponding distortion takes place in pad, changes the delivery port discharge section area, thereby keeps the irrigator flow constant substantially, reaches pressure compensated purpose, to improve uniformity of irrigation water appilcation.
Described pedestal 3 outer walls are used for dredging current with circulation chamber 10, to improve the performance of anti-blockage of irrigator, and such structure die sinking is easy, and cost is low, and manufacture deviation is little, directly reduced the cost of irrigator, from having reduced the cost of whole drip irrigation system in essence.
