Abstract
The utility model relates to a detachable regulator of small pipe irrigation system irrigator in water-saving irrigation equipment, which solves the problems that an existing small pipe irrigator regulator has poor blockage resistance. The detachable regulator comprises a base, a top cover and a circular elastic film plate, wherein a top cover outlet channel, a top cover pellet outer channel, a top cover pellet inner channel, a base cavity and a base inlet channel can form a regulator channel, the diameter of the top cover outlet channel is far smaller than the diameter of the base inlet channel, the width and depth of the pellet inner channel, the width and depth of the pellet outer channel and the dimension of the base cavity, the top cover is combined with the base through common screw threads to form an integral regulator, and the top cover can be detached from the base for flushing and can be reinstalled on the base.
Description
Affiliated technical field
The utility model relates to that tubule goes out a kind of washable flow straightener that system's douche is irrigate in purling in the water-saving irrigation device.
Background technology
The tubelet effluent irrigation system is that China is in applying the high-efficiency water-saving micro irrigation technology, for strengthening douche anti-blocking, a kind of high anti-blocking micro irrigation technology of foundation.At present, the flow straightener flow of tubelet effluent irrigation system douche is little, and its runner flow section size is little, anti-blocking is poor, and usually flow straightener is loaded on douche go out to flow the tubule entrance point, be connected with the water supply hollow billet be embedded in underground, in case stop up, discovery and processing are very difficult, influence uniformity of irrigation water appilcation, even cause irrigation system to lose efficacy, adopt high order to count filter inevitably in addition, clean inconvenience, power consumption is big, has increased the irrigation cost.
Summary of the invention
In order to remove the difficult problem of existing tubelet effluent irrigation system douche flow straightener anti-blocking difference, the utility model provides a kind of flow straightener that overcomes contradiction between low discharge and the big high anti-blocking of runner, it can keep the douche outflow little, it is stable to go out stream, the uniformity of irrigation water appilcation height, disassembly, cleaning easily again, time dress reset, and prevent that douche from stopping up, prolong irrigation system service life, save and irrigate cost.
The technical scheme that the utility model technical solution difficult problem is adopted is: flow straightener is installed in tubule top, puts as for ground.This flow straightener is made up of base, top cover and round and elastic diaphragm, the circulation road of going out is arranged at top cover top, one pellet is arranged in the top cover, the pellet lower surface has a trapezoidal cross-section groove, the pellet side has around the trapezoidal labyrinth type pellet outer flow passage above it, the ring-shaped groove that combines with base for top cover between pellet and the top cover sidewall; The influent stream passage is arranged at the base bottom, inner flexible diaphragm retainer plate; Top cover sidewall is combined into flow straightener integral body by the regular screw threads M20 and the base side wall outside; The round and elastic diaphragm is contained between top cover and the base, places on the base flexible sheet retainer plate, constitutes the pellet inner flow passage with top cover pellet lower surface trapezoidal cross-section groove, constitutes base intracavity with base flexible sheet retainer plate; Top cover goes out circulation road, pellet outer flow passage, pellet inner flow passage, base intracavity and base influent stream passage and is interconnected, constitute complete flow straightener runner, top cover goes out the circulation road diameter and is not more than 1.5mm, base influent stream channel diameter is not less than 2.0mm, pellet lower surface trapezoidal cross-section groove top width is not less than 2.0mm, pellet lower surface trapezoidal cross-section channel bottom is the rectangular cross section of bottom width 1.2mm and degree of depth 1.0mm, the wide not little 2.0mm of pellet outer flow passage, the pellet lower surface gash depth and the pellet outer flow passage degree of depth all are not less than 2.0mm; According to the actual needs, under the described size condition of this flow straightener runner each several part, adopt different size grade or flexible sheet different-thickness, form flow straightener specification series and corresponding flow value series, peak flow values is no more than 50L/h.
Operation principle of the present utility model is, during flow straightener work, irrigation water enters base intracavity by the tubule base influent stream passage of flowing through, the pellet inner flow passage of flowing through then enters the pellet outer flow passage, going out circulation road through top cover is flowed out by delivery port. because base intracavity velocity ratio pellet inner flow passage flow velocity is much smaller, water pressure is greater than the end face water pressure below the flexible sheet, force the flexible sheet distortion, recessed to the pellet inner flow passage, thereby reduce the pellet inner flow passage degree of depth, pellet inner flow passage cross section diminishes, hydraulic pressure is big more, the flexible sheet distortion is big more, the pellet inner flow passage degree of depth is more little, pellet inner flow passage cross section is more little, this does not change because of the tubule variation in water pressure with regard to making the flow by the pellet inner flow passage, make the douche flow keep basicly stable, afterwards, current enter top cover pellet outer flow passage, flow with turbulent condition, make discharge stability obtain further to strengthen. because top cover goes out circulation road and delivery port diameter than base influent stream passage and water inlet diameter, base intracavity, the pellet inner flow passage, the size of pellet outer flow passage is much smaller, the low discharge that had both kept douche, again before the solid particle deposition that enters the flow straightener runner by the base water inlet is stopped up top cover to go out circulation road runner any one the time, be easy to find, can pull down top cover at any time and wash.
