Description
Technical field
The utility model belongs to modern high-efficiency water-saving agricultural technology field, relates to the pressure balance adjuster in a kind of low-pressure drip irrigation system, particularly a kind of low water head hollow billet flow regulator.
Background technology
Drip irrigation is a kind of advanced person's a water-saving irrigation technique, and it mainly is to utilize pressure pipeline that irrigation water directly is delivered to crop root, has realized little quota localized irrigation.Traditional drip irrigation system is in order to adapt to rugged orographic condition, the design working head of emitter operating pressure is also higher relatively, usually reach about 10 meters, in order to improve the uniformity of irrigation water appilcation of drip irrigation system, except that crossing the employing pressure compensating emitter, the import department at hollow billet increases capillary pressure (flow) adjuster usually.In recent years, along with popularizing of drip irrigation system, drip irrigation technique obtains large-area promotion and application in flat area and green house.Less for Plain irrigation and green house topographical elevation difference, the influence that the drip irrigation system uniformity of irrigation water appilcation is produced diminishes thus, consider from energy savings in this situation, it is too high that the operating pressure of water dropper also just there is no need design, therefore drip irrigation system also just develops towards the low pressure direction at present, and its operating pressure will be below 5 meters.Because the loss of flood peak in the water-carriage system, pressure reduction between hollow billet certainly exists, comparatively responsive in low pressure condition down-off to pressure, in order not influence the uniformity of irrigation water appilcation of (reduction) adjuster, need the hollow billet flow regulator equally, and that traditional capillary pressure (flow) adjuster plays pressure regulation power is higher, generally about 10 meters, therefore the demand that can not adapt to low-pressure drip irrigation system needs a kind of pressure regulation power of research and development low, the low pressure flow adjuster of stable work in work.
Summary of the invention
Defective and deficiency at above-mentioned prior art existence, the purpose of this utility model is, provide a kind of to transfer operating pressure low, the low water head hollow billet flow regulator of controlled head about 2 meters, this adjuster is specially adapted to low-pressure drip irrigation system, make irrigation water from the flow unanimity that arm enters each hollow billet, guarantee that low-pressure drip irrigation system has higher uniformity of irrigation water appilcation.
The utility model is to finish by following technical scheme: a kind of low water head hollow billet flow regulator, comprise a housing, an end of housing has the water inlet that is connected with the tube wall of water-supply-pipe, core body of enclosure interior suit, core body one end has delivery port, and the other end communicates with the water inlet of housing; Be characterized in that core body is provided with regulating tank and secondary regulating tank, all be placed with elastic film on two regulating tanks, many runners are arranged on the regulating tank, streamlined curved surface back-up block is arranged on the runner; There is a trapezoidal runner secondary regulating tank below, is provided with half garden shape block in the trapezoidal runner, and streamlined oval support of a control flow velocity arranged on the semicircle block.Between water inlet regulating tank and secondary regulating tank, communicate by a gradual change shape runner.
Some other characteristics of the present utility model are, described regulating tank is circle or rectangle, when regulating tank is rectangle, 2 runners is arranged in the groove, and the section of runner is a rectangle, and distribution is in line; When regulating tank is circular, 4 runners are arranged in the groove, the section of runner also is a rectangle, and distribution is orthogonal.
Because the utility model has adopted the structure of regulating tank and secondary regulating tank, under low operating pressure, just can make the flow that enters each hollow billet reach unanimity after making irrigation water through twice adjusting of adjuster.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the core schematic diagram; A) being that core one end is cylindrical regulating tank wherein, b) is that a) A is to view; C) be that core is the rectangle regulating tank, d) be c) A to view.
Symbol among the figure is represented respectively: 1, housing 2, water inlet 3, delivery port 4, core body 5, water inlet flow channel 6, gradual change runner 7, ovally support 8, semicircle block 9, secondary regulating tank 10, regulating tank 11, streamlined support 12, trapezoidal runner.
Embodiment
The embodiment that provides below in conjunction with accompanying drawing and inventor is described in further detail the utility model.
According to technique scheme, low water head hollow billet flow regulator, comprise housing 1, the water inlet 2 of housing 1 one ends links to each other with the tube wall of water-supply-pipe, core body 4 of enclosure interior suit, core body 4 one ends be exposed to housing 1 outer be delivery port 3, the other end communicates with the water inlet 2 of housing 11 li of housing, two regulating tanks is arranged, i.e. regulating tank 10 and secondary regulating tank 9 on the core body 4, regulate on the groove face for two and all be placed with elastic film, regulating tank 10 is key components of low water head hollow billet flow regulator, and irrigation water is here regulated earlier, the loss part energy, enter secondary regulating tank 9, guaranteed that adjuster under low pressure still can regulate.
Above-mentioned housing 1 can be made into cylindrical, and core body 4 is corresponding with housing 1.Regulating tank 10 designs have the rectangle of 2 runners or the circle of 4 runners are arranged, all there is the streamlined curved surface to support 11 on the runner 5, the section configuration of runner 5 is a rectangle, secondary regulating tank 9 belows are trapezoidal runners 12, in be provided with semicircle block 8, there be the streamlined oval of a control flow velocity to support 7 on the semicircle block 8, between regulating tank 10 and secondary regulating tank 9, be connected by a gradual change runner 6, after irrigation water enters housing 1 from water inlet 2, enter regulating tank 10 from runner 5 and carry out the first time and regulate, the water loss after overregulating part energy, enter trapezoidal runner 12 through runner 6 again, accept secondary and regulate, enter hollow billet from delivery port 3 at last.After irrigation water process twice pressure of adjuster and the Flow-rate adjustment, under low operating pressure, make the flow that enters each hollow billet reach consistent.
Above-mentioned regulating tank can be circle or rectangle, when regulating tank is rectangle, 2 runners is arranged in the groove, and the section of runner is a rectangle, and distribution is in line; When regulating tank is circle, 4 runners are arranged in the groove, the section of runner also is a rectangle, distribution is orthogonal.
