Abstract
The utility model relates to an integrated anti-blocking pressure compensation irrigator. The circumference of the irrigator is arranged with an inclined trapezoid labyrinth flowing path and a triangle labyrinth flowing path is arranged beneath an elastic diaphragm in the pressure adjusting area of the irrigator. The irrigator has an integrated structure with a simple structure and a high precision, which needs no an independent designed elastic diaphragm to press a location lid. When the pressure compensation irrigator works, the pressure water which enters into the irrigator through an irrigator inlet grid flows through the labyrinth flowing path in the circumference of the irrigator and thus enters the pressure compensation area. The distortion of the elastic diaphragm changes as the change of the inlet pressure and thus the length of the labyrinth flowing path where the water flows changes, which can adjust the outlet flow of the pressure compensation irrigator to keep the outlet flow invariable. Therefore the outlet flow can be controlled invariably precisely by changing the length of the labyrinth flowing path where the water flows. And when the flow pressure changes the sectional area of the water outlet will keep invariable, which improves the anti-blocking performance.
Description
Technical field
The utility model relates to a kind of irrigator of agricultural water conservation, and the anti-stifled pressure of particularly a kind of integral type is repaid irrigator.
Background technology
In the existing various irrigator, plain edition is to regulate its water yield by pressure of supply water, and the pressure-compensated irrigator is under different inlet pressures, guarantees that water yield is even substantially.Existing pressure compensation water dropper generally assembles with upper member by 3, owing to be subjected to the influence of the factors such as precision, workpiece, quality of materials and operating personnel's technical ability of mould, all there is certain error in each member of producing.Even the qualified member that promptly satisfies the requirement of quality standard also can produce certain error through behind the assembling procedure, thereby influence the stability of pressure compensating emitter water outlet.Therefore in order to improve the job stability of compensation water dropper, should reduce the number of member as far as possible.And existing pressure compensation douche generally is to realize pressure compensation by the area of passage that changes delivery port, but along with the increasing of pressure, area of passage also reduces thereupon, so just occurs clogging easily.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, a kind of structure is provided and has assembled the anti-stifled pressure compensation douche of the integral type simple, that precision is high.
For achieving the above object, the technical solution adopted in the utility model is: comprise the water dropper body that is provided with the entry grid, be characterized in, the circumference of water dropper body is provided with the inclined ladder shape labyrinth flow-path that is connected with the entry grid, on the water dropper body, also be provided with the pressure regulation district, this pressure regulation district comprises draw-in groove and is arranged on the interior flap that matches with draw-in groove of draw-in groove, and the lower end at flap is provided with flexible sheet, also be provided with the triangle labyrinth flow-path that has water inlet and delivery port in the lower end of flexible sheet, the triangle labyrinth flow-path is connected with inclined ladder shape labyrinth flow-path by water inlet.
Another characteristics of the present utility model are: the two ends of water dropper body also offer the cannelure of a symmetry respectively; Also be provided with the flap projection on the flap, flap is arranged in the draw-in groove by the flap projection; The section of triangle labyrinth flow-path is the inclined-plane form, and is near more from the irrigator delivery port, and the distance between triangle labyrinth flow-path and the flexible sheet is big more.
Because the utility model does not need independent design flexibility pressing diaphragm tightening position lid, constitute by water dropper body and adjusting diaphragm two parts, assembling is simple, precision is high.Irrigator is except arranging inclined ladder shape labyrinth flow-path on its circumference, also design has the triangle labyrinth flow-path under the flexible sheet in its pressure regulation district.When irrigator changes at pressure, by changing the length of current by the triangle labyrinth flow-path, rather than regulate flow by the cross dimensions that changes runner, when compensating coefficient, can keep bigger outlet section equally like this, thereby realize that by the cross dimensions that changes delivery port pressure compensated irrigator compares with existing, improved anti-obstruction.

Embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are described in further detail.
Referring to Fig. 1-6, the utility model comprises water dropper body 2, offer the cannelure 7 of symmetry respectively at the two ends of water dropper body 2, on water dropper body 2, also be provided with entry grid 5, the circumference of water dropper body 2 is provided with the inclined ladder shape labyrinth flow-path 1 that is connected with entry grid 5, also be provided with pressure regulation district 8 on the water dropper body 2, this pressure regulation district 8 comprises draw-in groove 9 and has the flap 6 of flap projection 12, but flap 6 is clamped in the draw-in groove 9 by 12 bendings of flap projection, and be provided with flexible sheet 11 in the lower end of flap 6, also be provided with the triangle labyrinth flow-path 10 that has water inlet 3 and delivery port 4 in the lower end of flexible sheet 11, triangle labyrinth flow-path 10 is connected with inclined ladder shape labyrinth flow-path 1 by water inlet 3, the section of this triangle labyrinth flow-path 10 is the inclined-plane form, near more from irrigator delivery port 4, the distance between triangle labyrinth flow-path 10 and the flexible sheet 11 is big more.
The course of work of the present utility model is as follows: current enter the inclined ladder shape labyrinth flow-path 1 that is arranged on water dropper body 2 circumference by the entry grid 5 of water dropper body 2 one ends, after 1 energy dissipating of inclined ladder shape labyrinth flow-path, enter pressure regulation district 8 by water inlet 3, by the triangle labyrinth flow-path 10 in the pressure regulation district 8, flow out again by delivery port 4.The utility model is realized accurately control flow by the variation of the contact length of flexible sheet 11 and triangle labyrinth flow-path 10, when pressure is low, it is short that flexible sheet 11 covers the length of triangle labyrinth flow-path 10, and current (are seen Fig. 5 a) by the length of triangle labyrinth flow-path 10 is also short; When pressure was high, the length of the triangle labyrinth flow-path 10 that flexible sheet 11 covers was elongated, and current are by long triangle labyrinth flow-path 10, entered the water flow pressure in pressure regulation district 8 like this when high, and labyrinth flow-path 10 working regions are long, and energy dissipating is many; When pressure hanged down, labyrinth flow-path 10 working regions were short, and energy dissipating is few, thereby has realized the constant of rate of discharge, and whole procedure exit section all is constant.
