Abstract
The utility model relates to an anti-blocking symmetric-runner pressure compensated type water dropper which comprises a silicon piece which is arranged between an upper cover of the water dropper and a lower cover of the water dropper, and a water outlet is arranged in the middle of the upper cover of the water dropper. The anti-blocking symmetric-runner pressure compensated type water dropper is characterized in that runners are symmetrically distributed on two sides of the water outlet, water inlets are arranged on four corners of the lower end of the water dropper, 23 filter windows are respectively arranged on the upper side and the lower side of the water dropper, and transverse and vertical strip-type veins are arranged in the middle of the water dropper. The anti-blocking symmetric-runner pressure compensated type water dropper has the advantages of being good in pressure compensated performance, strong in anti-blocking performance and good in water outflow uniform performance.
Description
Technical field
The utility model relates to the water dropper in the drip irrigation equipment, relates in particular to a kind of anti-obstruction balance runner pressure compensating emitter.
Background technology
Drip irrigation is one of typical application form of micro irrigation technology, is one of most advanced irrigation technique of economizing on water most of up to now field irrigation.Drip irrigation technique has obvious water-saving and yield-increasing benefit.The drip irrigation economize equipment is the core of water saving, and water dropper is the core component in the drip irrigation system, and whether the water dropper design has rationally determined the service life of quality, management cost and the drip irrigation equipment of drip irrigation.The normal problem that occurs of drip irrigation mainly is that its spill along the overfall weir amount is even not, and local water yield general far away apart from the water source is less.For guarantee under the different water droppers each water dropper in the unit interval amount of dripping basically identical, people develop the focus that multi-form compensation water dropper becomes this field at present.When hydraulic pressure was large, water velocity was fast, but runner water inlet sectional area is little; When hydraulic pressure hour, water velocity is slow, but runner water inlet sectional area is relatively large, so just can effectively guarantee in water dropper the drip amount of different water dropper in the unit interval basic identical, thereby realize the compensation of pressure and flow.Both at home and abroad the technical research worker makes every effort to research and develop the strong water dropper of anti-blockage capability, has water dropper from washing capacity as enlarging emitter flow channel cross section and exploitation.But present water dropper product both domestic and external, the long-pending increase of its cross section of fluid channel is limited, and the long-pending size of cross section of fluid channel is still in stopping up sensitive range.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of have better pressure compensation performance, performance of anti-blockage is strong, the even performance of water outlet is good anti-obstruction balance runner pressure compensating emitter.
For addressing the above problem, a kind of anti-obstruction balance runner pressure compensating emitter described in the utility model comprises the silica gel piece between water dropper loam cake and water dropper lower cover; The middle part of described water dropper loam cake is provided with delivery port, it is characterized in that: the bilateral symmetry of described delivery port is distributed with runner; Four jiaos of described water dropper lower cover are equipped with water inlet, 23 filter windows that its upper and lower side is respectively equipped with, and its middle part is provided with anyhow bar shaped line.
Be provided with groove around the described delivery port, this groove and described silica gel piece are complementary; Described silica gel piece and described anyhow bar shaped line are complementary.
Being interconnected between 23 described filter windows separately of the upper and lower side of described water dropper lower cover.
The utility model compared with prior art has the following advantages:
1, because the utility model water dropper body reverse side is provided with 46 filter windows, and filter window number has increased by 2 times, and being interconnected between 23 filter windows separately of upper and lower side, therefore, greatly improved anti-blockage capability.
2, because 4 water inlets of the utility model by being covered with under the water dropper, increased the number of water inlet, anti-blockage capability has obtained large increase, and when occuring to stop up less than 4 water inlets, other water inlet still can continue to supply water, therefore, can reduce and prevent that crop from causing the phenomenon of the death of crop and the significantly underproduction to occur in lack of water season.
3, after the utility model made current enter groove through two side runners by the balance runner that is covered with on the water dropper, because water inlet is less, two strands of current were gathered in the groove, thereby reach energy dissipating, realized the purpose of current stabilization; When a runner occurs to stop up, has complementary washing capacity between two runners.Therefore, this kind changes the mode of flow passage structure and intake-outlet, effectively solved water dropper and easily stopped up and the poor problem of compensation effect.Simultaneously, when a side runner stopped up, the opposite side runner also had washing capacity, will play certain facilitation service life for improving emitter clogging and prolonging water dropper.
4, owing to being provided with silica gel piece in the utility model, because silica gel piece has certain elasticity, and bar shaped line wall thickness is thinner anyhow, when hydraulic pressure changes, by the anyhow bar shaped line of setting and the interaction adjust flux between the silica gel piece.Along with the increase of hydraulic pressure, larger to the active force of silica gel piece by the bar shaped line, outflow reduces, and compensation effect is obvious.
5, since in the utility model water dropper loam cake runner all be positioned at the inboard, therefore, stopped runner and be positioned at when outside, water dropper to the obstruction of emitter flow channel, and then causes impact on the water dropper flow during with the drip irrigation pipe stickup, has made things convenient for processing technology.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Among the figure: 1-water dropper loam cake, 2-runner, 3-groove, 4-delivery port, 5-silica gel piece, 6-water dropper lower cover, 7-water inlet, 8-anyhow bar shaped lines 9-filter window.
The specific embodiment
As shown in Figure 1, a kind of anti-obstruction balance runner pressure compensating emitter comprises the silica gel piece 5 between water dropper loam cake 1 and water dropper lower cover 6.The middle part of water dropper loam cake 1 is provided with delivery port 4, and the bilateral symmetry of this delivery port 4 is distributed with runner 2; Four jiaos of water dropper lower cover 6 are equipped with water inlet 7,23 filter windows 9 that its upper and lower side is respectively equipped with, and its middle part is provided with anyhow bar shaped line 8.
Wherein: be provided with groove 3 around the delivery port 4, this groove 3 is complementary with silica gel piece 5; Silica gel piece 5 is complementary with bar shaped line 8 anyhow.
Being interconnected between 23 filter windows 9 separately of water dropper lower cover 6 upper and lower sides.
Operation principle: current enter balance runner 2 by the water inlet 7 in the water dropper lower cover 6, and current flow in opposite directions, and the balance runner 2 by water dropper loam cake 1 comes together in groove 3, flows out by the delivery ports 4 in the groove 3.
