The utility model can the size by changing 21 aperture of water outlet and size with pressure compensation subaisle 16, Obtain the different flow specification from 20~400L/h.
The micro- spray adapter 2 of pressure compensation includes by shell 7 and ontology 8;Shell 7 is substantially cylindrical, inside there is different-diameter Through-hole, there are two symmetrical groove 30, the locking boss 31 being arranged on groove and ontology 8 cooperates oral area.Ontology 8 it is interior Hole is consistent with the outer diameter of part that shell 7 is inserted into, and forms sealing state.It is equipped between shell 7 and ontology 8 for placing sealing The mounting groove 11 of circle 9.
The inside of the micro- spray adapter 2 of pressure compensation is cavity, pressure compensation platform 15 is equipped in cavity, in pressure compensation platform 15 are equipped with pressure compensation chip 10, and pressure compensation chip 10 and the micro- inner wall for spraying 2 side of adapter of pressure compensation are constituted and pressed The pressure compensation platform 15 of force compensating chamber 12, pressure compensation chip 10 and inside constitutes pressure compensation chamber 13,15 He of pressure compensation platform Pressure compensation cavity 18, upper pressure compensation chamber 12 and pressure compensation after the inner wall of micro- spray 2 other side of adapter of pressure compensation is constituted The cavity of 10 lower section of chip is set as lower pressure compensation chamber 17;
The water inlet end of lower pressure compensation chamber 17 is connected to the hollow billet interface 6 for being located at micro- spray 2 bottom of adapter of pressure compensation, under The water outlet of pressure compensation chamber 17 is connected to upper pressure compensation chamber 12 and pressure compensation chamber 13 respectively, is opened on pressure compensation platform 15 Equipped with pressure compensation subaisle 16, pressure compensation chamber 13 is connected to by pressure compensation subaisle 16 with rear pressure compensation cavity 18, The water outlet of pressure compensation cavity 18 is connected to the turbulent chamber 20 for being located at micro- 2 top of spray adapter of pressure compensation afterwards, turbulent chamber 20 Water outlet with rotation mini sprinkler 1 be connected to.
In above-mentioned each component, the internal diameter of hollow billet interface 6 is 2mm, and outside is cone mouth.
Pressure compensation platform 15 is located on ontology 8, and structure is cylinder boss, and 4~6mm of diameter, height 2MM, there is pressure at center Force compensating subaisle 16,16 1~3mm of diameter of pressure compensation subaisle.
Pressure compensation subaisle 16 is located in the plane of pressure compensation platform 15, and width is 0.5~1mm, and length and pressure are mended It is consistent to repay 15 diameter of platform, depth is 0.3~1mm.
Pressure compensation chip 10 is the elastic chip of waist type structure, and thickness 1.2mm is located on pressure compensation mounting table 19, Upper pressure compensation chamber 12 is separated with pressure compensation chamber 13, and guarantees the sealing on periphery.
Upper pressure compensation chamber 12 is the cavity formed by 10 outer surface of pressure compensation piece and 7 inner wall of shell, and in pushing Force compensating 17 is connected to by runner.
Pressure compensation chamber 13 is located at upper pressure compensation chamber 12, lower pressure compensation chamber 17, between rear pressure compensation chamber 18.Pressure Compensated cavity 13 passes through pressure compensation subaisle 16 and rear pressure by through-hole 14 and lower 17 connection of pressure compensation chamber, pressure compensation chamber 13 Force compensating chamber 18 is connected to.
Pressure compensation chamber 17, through the upper and lower part of ontology 8, and some is distributed parallelly on rear pressure compensation chamber 18 The lower section of pressure compensation chamber.
Pressure compensation chamber 18 afterwards, main body are the flow channel shape of W type, pressure compensation of the water flow from 15 centre of pressure compensation platform Subaisle 16 enters to fall the center of " W " type runner, then flows out from both sides " v ", into turbulent chamber 20.
Pressure compensation chip mounting table 19, level height are 2mm higher than 15 pressure compensation platforms.
Turbulent chamber 20, the fuisw rib that design has 8 rules to be distributed on its circular conical surface, current stabilization water is quickly guided, and is injected The water outlet 21 of nozzle 3.
The water outlet 21 of nozzle 3, diameter are 0.5~1.4mm, and import is big, outlet is small, so that flow rate of water flow becomes faster, are formed The small water column of high speed is injected in the runner of spray disk, is provided spray and is spiraled rotatory force.
The pressure compensation process of the utility model is as follows:
1) after pressure water enters lower pressure compensation chamber 17 by hollow billet interface 6, a part of pressure water can by runner into Enter upper pressure compensation chamber 12, another part of pressure water can enter pressure compensation chamber 13 by through-hole 14;
2) since the cross section of fluid channel product that lower pressure compensation chamber 17 is connected to upper pressure compensation chamber 12 is greater than the section of through-hole 14 Product, the water intake velocity of lower pressure compensation chamber 17 can be greater than the water intake velocity of pressure compensation chamber 13, therefore in upper pressure compensation chamber 12 Hydraulic pressure can be greater than the hydraulic pressure in pressure compensation chamber 13, pressure between upper pressure compensation chamber 12 and pressure compensation chamber 13 is mended Significantly deformation can be occurred to 15 direction of pressure compensation platform under the action of differential water pressures by repaying chip 10;
3) after upper pressure compensation chamber 12 and pressure compensation chamber 13 fill water, since upper pressure compensation chamber 12 and pressure are mended It repays chamber 13 to be interconnected, the hydraulic pressure of upper pressure compensation chamber 12 and pressure compensation chamber 13 reaches unanimity, the shape of pressure compensation chip 10 Change can restore;
4) in above process, the partial pressure water in pressure compensation chamber 13 can be entered by pressure compensation subaisle 16 Afterwards in pressure compensation cavity 18, the hydraulic pressure of pressure compensation chamber 13 is caused to be slightly smaller than the hydraulic pressure of upper pressure compensation chamber 12, pressure compensation Chip 10 eventually keeps deformation by a small margin.
In certain small pressure limit when (5~200kPa), water flow can only all pass through complete pressure compensation subaisle 16 enter rear pressure compensation chamber 18, and are offset opposite when 2kPa in the section 0.5~2kPa by the design of " w " runner The relative energy of 0.5kPa keeps the stabilization of flow;
When in relatively large pressure limit when (200~400Pa), the transnormal deformation type of pressure compensation chip 10 Become rule, bear huge special-shaped deformation, the big position of pressure difference especially at pressure compensation subaisle 16, pressure compensation chip 10 becomes Shaped position partially enters in pressure compensation subaisle 16 with pressure increase, changes in pressure compensation subaisle 16 Cross-sectional area and volume, to reach different pressures compensation 16 cross-sectional area of subaisle and high pressure high flow rate under different relatively high pressures Matching, finally also reach the consistency of flow.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model Claimed range is defined by the appending claims and its equivalent thereof.
