Embodiment
Below in conjunction with accompanying drawing and example concrete working method of the present invention is done further detailed elaboration:
The present invention requires irrigator in certain working head (pressure) scope, obtains stable water flow.As shown in Figure 1, irrigator of the present invention comprises three chief components: water inlet block 1, water outlet block 2 and runner section 3.The chief component of irrigator and the situation that cooperatively interacts as can be seen from Figure 1, the water outlet end face of water outlet block 2 sealing runner section 3, the water inlet end face of 1 sealing of water inlet block runner section simultaneously, thus form the final two-sided flow passage structure of irrigator.
Fig. 2 is the structural representation of water inlet block 1, puts plastic tube in water supply connector 12 and introduces working flow.The water inlet bulge loop 14 of block on the inner face snaps in the water inlet deep gouge 7 on the water inlet end face of runner section 2, prevent current from around directly infiltrate among the runner that stillpot constitutes.Recessed pin 13 shown in the figure cooperates with the protruding pin 16 of water outlet block 2, has formed the fixedly snap close function of irrigator each several part.Anti-skid structure when in addition, being the irrigator assembling as the bar shaped gusset 11 among the figure.
As shown in Figure 3, two of two-sided runner section 3 end faces are provided with two kinds of runners of different structure form.The middle part of water inlet end face is a water inlet deep gouge 7, is distributed with some stillpots 8 around it.The edge of water inlet deep gouge 7 is provided with the breach 6 that links to each other with first stillpot 8, and per two stillpots 8 are linked to each other by a short and small passage 6, make whole runner form a loop chain.In the end be provided with filter screen 5 in a stillpot 8, as the delivery port of this runner, and link to each other with runner on the water outlet end face, wherein filter screen has played the effect of water outlet and filtration.The water outlet end face is provided with the plane labyrinth path 10 of ring-type, and its middle part is provided with the water outlet deep gouge 9 that links to each other with runner 10 outlets.The cross-sectional area of stillpot 8 is preferably 2-3 doubly much larger than the cross-sectional area of labyrinth path 10.
As a kind of example, water inlet deep gouge 7 and water outlet deep gouge 9 are circle, and stillpot 8 be the big or small fan groove identical with shape, be evenly distributed on water deep gouge 7 into around.The cellular construction of labyrinth path adopts zigzag, and the crown angle is 30 ° (crown angles between 10-30 ° also can), and section is a rectangle.
Fig. 4 is the structural representation of irrigator water outlet block 2, put plastic tube at water out adapter 18 and derive working flow, wherein 19 same water inlet bulge loops 14 of water outlet bulge loop have identical functions, the function of protruding pin 16 is above being set forth, wrench device when ear shape gusset 17 is the irrigator assembling, groove 15 shown in the figure realizes that with the boss 4 mutual interlocks of runner part 3 block is spacing with the cooperation of runner part.Two blocks have mainly played the effect that seals runner and the assembling of auxiliary irrigator up and down.Realize the demountable structure design of irrigator, except the assembly method of above statement, can also adopt other multiple fit, as adopting screw fit etc.In addition, be provided with the ring-type bulge loop on the end face contacting with runner of block, section is a rectangle.This bulge loop is inserted among the deep gouge on the runner end face when block partly assembles with runner, has prevented that effectively current from directly entering among the runner.
Current flow into water inlet deep gouge 7 with certain working head from water inlet block 1, enter first stillpot 8 from the breach of water inlet deep gouge edge, because the size of stillpot is relatively large, so current are comparatively slow, and are difficult for forming rapid whirlpool.Then enter next stillpot by breach 6, stillpot to the last so circulates.Move the filter screen 5 of mild current in stillpot and enter into the other end.On the other end, current move along labyrinth path 10 then from the inlet of filter screen 5 inflow labyrinth paths, finally arrive in the water outlet deep gouge 9, and flow out irrigators through water outlet block 2.So far, irrigator has been finished whole process from inlet water to outlet water.
More than set forth the design feature and the course of work of irrigator, below the operation principle of main explanation irrigator.The main feature of this irrigator is to have introduced two-sided flow passage structure, has adopted the stillpot of ring-type and the plane labyrinth flow-path of broached-tooth design here respectively as a kind of example of this invention.Current at first enter among first runner of being made up of a plurality of stillpots, because each stillpot is separate and size is bigger, make current the feature of discontinuity occur, and flow velocity is slow in each sedimentation basin simultaneously, does not form rapid whirlpool.In the flow field of this kind fluidised form feature, the solid particle that density is bigger precipitates easily, because the size of runner is bigger, so also be not enough to stop up whole runner.Therefore the runner that has this kind design feature has solved the susceptible to plugging difficult problem of irrigator effectively for irrigator provides the preformed precipitate effect of solid particle.On the other hand, second of irrigator runner then provides effect of energy dissipation more efficiently for it.Current will overcome the effect of frictional resistance on the one hand when the labyrinth flow-path of zigzag structure that is not more than 30 ° through the crown angle; On the other hand, because the corner of runner is anxious, many and continuous turning forms whirlpool easily, these whirlpools also have certain energy dissipating effect; Moreover because runner on the whole in the form of a ring, current also will overcome action of centrifugal force.The acting in conjunction of above-mentioned three aspects makes the energy of current obtain bigger consumption in short distance, has realized the energy dissipating and the pressure regulation effect of irrigator.Flow-shape in this runner shows as full turbulent flow, and its fluidised form index is about 0.5, and the teeth groove structure of labyrinth flow-path and size have then determined the water flow of irrigator.
In sum, this douche has creatively been introduced double-sided runner, effectively Solve more efficient effect of energy dissipation is provided when douche easily stops up a difficult problem; In addition, douche has also adopted dismountable structural design, makes its assembling and safeguards More simple and convenient.
