Abstract
The utility model discloses an anti-blockage drip irrigation emitter. The anti-blockage drip irrigation emitter is characterized by comprising a top cover, a water dripper, a flow stabilizing valve and a filter, the upper end of the top cover is a quick joint, the lower end of the top cover is connected with the dripper, the filter is arranged at the joint of the upper end of the dripper and the top cover, the flow stabilizing valve is arranged in the dripper, and the inside of the dripper is divided into a water inlet cavity at the upper end and a buffer cavity at the lower end. The anti-blockage drip irrigation emitter is simple in structure, low in cost, convenient and quick to use, good in anti-blockage effect and capable of meeting requirements of the market.
Description
Technical field
The utility model relates to the field irrigation field, relates in particular to a kind of anti-clogging and irrigates drip irrigation emitter.
Background technology
Drip irrigation is to utilize plastic conduit that water is delivered to crop root by the aperture on the hollow billet or water dropper to carry out localized irrigation, is the most effective a kind of Water Saving Irrigation Mode in present drought and water shortage area, and the utilization rate of water can reach 95%.Drip irrigation is sprayed and is had higher water-saving and yield-increasing effect, can improve fertilizer efficiency more than one times in conjunction with fertilising simultaneously, irrigates applicable to fruit tree, vegetables, industrial crops and warmhouse booth, also can be used for field crop irrigation in the place of drought and water shortage.
The weak point of drip irrigation is the easy fouling of water dropper and obstruction, and chemical method or physical method are generally adopted in the at present anti-obstruction of drip emitter.The chemical method specification requirement is high, except a few countries such as the U.S., does not generally use.The anti-obstruction of physical method is the method that generally adopts, and researcher or the personage among the people of specialty have carried out unremitting effort for the performance that improves the anti-obstruction of physical method, but up to the present, the defective that drip emitter stops up does not still solve well.The main cause of this situation is the physical method of existing anti-obstruction, or the sticking shape tamper poor effect that produces removing biological bacterium, even has no way out, or structure is too complicated, and investment is large, produces and constructional difficulties, is difficult to be generalizable.
The utility model content
The utility model has overcome deficiency of the prior art, provides the better anti-clogging of a kind of anti-blocking performance to irrigate drip irrigation emitter.
In order to realize above-mentioned purpose, adopt following technical scheme: drip irrigation emitter is irrigated in a kind of anti-clogging, described drip irrigation emitter comprises top cover, water dropper, flow stabilizing valve and filter, described top cover upper end is fast joint, the lower end is connected with water dropper, described filter is arranged on the junction of water dropper upper end and top cover, and described flow stabilizing valve is arranged on water dropper inside, and water dropper inside is divided into the intake antrum of upper end and the cushion chamber of lower end.Fast joint directly inserts in the hollow billet, and current enter top cover from hollow billet, enters intake antrum through behind the filter, down oozes from cushion chamber through behind the flow stabilizing valve again.Because current enter water dropper again through filtering first, have strengthened anti-blocking effect.
In the such scheme, described top cover is connected buckle structure with water dropper and connects, and is simple in structure, connects simple and efficient.
In the such scheme, described intake antrum is cylindrical, and cushion chamber is taper, and such structure can effectively cooperate cap structure, can play to current again the effect of buffering.
In the such scheme, described water dropper lower end has cross recess, and described flow stabilizing valve center has cross star otch, and water dropper and flow stabilizing valve are made by elastomeric material.When four tongue pieces of cross star otch are drawn close fully to center curvature, can not complete closed, the center will be reserved and prevent the flowing hole shut.Water dropper and flow stabilizing valve adopt for example silicone rubber or silica gel elastomeric material, and filter adopts resistant material.
Compared with prior art, the utility model is simple in structure, and cost is low, and is convenient to use, and anti-clogging is effective, demand that can satisfying the market.
Description of drawings
Fig. 1 is sectional view of the present utility model.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Structure of the present utility model mainly comprises top cover 1, water dropper 2, flow stabilizing valve 3 and filter 4 as shown in Figure 1.Top cover 1 and water dropper 2 are connected by buckle structure, and flow stabilizing valve 3 is arranged on water dropper 2 inside, and filter 4 is installed between top cover 1 and the water dropper 2.Top cover 1 upper end is provided with fast joint 11, and the centre is water inlet flow channel 12.Flow stabilizing valve 3 is divided into intake antrum 21 and cushion chamber 22 with water dropper 2 inside, and flow stabilizing valve 3 centers have cross star otch 31, and water dropper 2 lower ends have cross recess 23.
After entering the normal irrigation state, if pressure of supply water increases, intake antrum 21 also increases with the pressure reduction of cushion chamber 22 thereupon, and four tongue pieces of the cross star otch 31 of flow stabilizing valve 3 are further increased to the degree of runner center curvature, and area of passage also further dwindles; Otherwise, pressure of supply water reduces, intake antrum 21 also reduces with the pressure reduction of cushion chamber 22 thereupon, four tongue pieces of the cross star otch 31 of flow stabilizing valve 3 are also further reduced to the degree of runner center curvature, area of passage further enlarges, be that area of passage and pressure of supply water are the inverse ratio variation, operating pressure when making the normal irrigation of cushion chamber 22 does not change with pressure of supply water, operating pressure when acting on the normal irrigation of cross recess 23 is constant, the outflow of cross recess 23 is also constant, keeps constant.
In case cross recess 23 stops up, pressure in the cushion chamber 22 rises rapidly, operating pressure in the time of will having far above normal irrigation acts on cross recess 23, until tamper is gone out, pressure in the cushion chamber 22 descend rapidly, and under the effect of intake antrum 21 and cushion chamber 22 pressure reduction, flow stabilizing valve 3 will regulate that cushion chamber 22 interior pressure enter or the operating pressure when coming back to normal irrigation, enter or come back to the normal irrigation state, the self-regeneration process that automatically having finished boosts stops up.
The above-mentioned course of work, the pressure that acts on cross recess 23 is followed successively by: automatic boosting removes the pressure of the pressure of the self-regeneration process stopped up＞when the pressure of flushing process＞normal irrigation, and the opening width size sequence of corresponding cross recess 23 also is like this with it.
