Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment the present invention is further illustrated, but protection scope of the present invention is simultaneously
Not limited to this.
Referring to the drawings 1 to accompanying drawing 4, rocker-arm sprinkling irrigation sprinkler head includes auxiliary jet device 1, elbow 2, jet pipe 3, main burner 4, sky
Heart axle 5 and swivel connecting seat 6, auxiliary jet device 1 are arranged on elbow 2.The auxiliary jet device 1 include auxiliary jet housing 11,
Regulation spring 12, auxiliary jet inner core 13, stop collar 14 and sealing ring 15.The auxiliary jet inner core 13 is sleeved on auxiliary jet housing 11
Inner side, auxiliary jet housing 11 is concentric with auxiliary jet inner core 13 to be installed, and guide section 131 stretches out pilot hole 111.
Pilot hole 111, water seal stria 112, the first conical section 113, the second conical section are machined with auxiliary jet housing 11
114th, the second flow-out hole 115, the cylindrical section 117 of step 116 and second, are machined with guide section 131, first go out on auxiliary jet inner core 13
Discharge orifice 132, tapered portion 133, cylindrical portion 134, guiding rib 135, the 4th conical section 136, seal groove 137；Guide section 131 is set in
The inner side of pilot hole 111, for gap coordinates between guide section 131 and pilot hole 111, water seal stria 112 is arranged at pilot hole 111
Centre position, to seal the gap between guide section 131 and pilot hole 111, prevents auxiliary jet housing 11 and auxiliary jet inner core 13
Between working fluid sprayed in gap between guide section 131 and pilot hole 111；Guiding rib 135 and second straight line section 117
Between be gap coordinate, to limit the movement of auxiliary jet inner core 13, at the same can reduce guiding rib 135 and second straight line section 117 it
Between frictional resistance.
The 0.3~0.6 of the diameter of a diameter of main burner 4 in first outlet hole 132, a diameter of the first of the second flow-out hole 115
The 0.4~0.7 of the diameter of flow-out hole 132, to realize the working fluid supplement sprinkling domain mesozone that the first flow-out hole 132 is sprayed
The water distribution in domain, the water distribution at the working fluid supplement sprinkling nearly shower nozzle in domain that the second flow-out hole 115 is sprayed.
Second conical section 114 is parallel with the 4th conical section 136, can under high pressure separate working fluid, is pressed when shower nozzle works
When power increases to certain value, water pressure pushing auxiliary jet inner core 13 is slided to the direction of pilot hole 111, so as to drive the second conical section
114 and the 4th conical section 136 fit, under the collective effect of sealing ring 15, the working fluid that can completely cut off in annular channel 16 enters
Enter the second flow-out hole 115, the not operation of the second flow-out hole 115.
Regulation spring 12 is set between auxiliary jet housing 11 and auxiliary jet inner core 13, stop collar 14 is connected through a screw thread dress
In the inner side of auxiliary jet housing 11, by adjusting the installation site of stop collar 14, realize to the regulation pretension of spring 12, it is ensured that low
The second sprinkling passage is unimpeded under pressure operating mode, and working fluid can enter the second flow-out hole 115, and this external position limited sleeve 14 can limits nozzle
The position of inner core 13, under preventing off working state, under the elastic force effect of regulation spring 12, spraying nozzle inner core 13 is from auxiliary jet shell
Come off in body 11.
Referring to the drawings 6, secondary pod apertures 141 and leading discharge orifice 142 are machined with the stop collar 14, secondary pod apertures 141 are
Second sprinkling passage provides working fluid, and leading discharge orifice 142 provides working fluid for the first sprinkling passage.To realize that first goes out stream
The sprinkling region different with the working fluid covering that the second flow-out hole 115 is sprayed of hole 132, the area of passage of secondary pod apertures 141
It is not more than 0.4 with the ratio between the area of passage of leading discharge orifice 142.
The course of work of shower nozzle is：
Under low pressure operating mode, because operating pressure is relatively low, under the pretightning force effect of regulation spring 12, on secondary spray group housing 11
The second conical section 114 and auxiliary jet inner core 13 on the 4th conical section 136 do not fit also, small part working flow is by spacing
Secondary pod apertures 141 on set 14 enter annular channel 16, are sprayed from the second flow-out hole 115, the second sprinkling passage covering sprinkling domain
Region near interior close shower nozzle；Part working flow enters auxiliary jet inner core 13 from leading discharge orifice 142, and from the first flow-out hole
132 spray, the region in the first sprinkling passage covering sprinkling domain near medium range；Most of current spray from the main burner 4 of shower nozzle
Go out, the water distribution in main covering sprinkling domain at middle Far Range；By 3 bursts of different works of distinct coverage region of overlay area
Make current collective effect, realize uniformly being sprayed under low pressure.
When operating pressure at sprinkler is improved to be worked to rated pressure, water pressure pushing auxiliary jet inner core 13 is to pilot hole
111 direction is slided, and regulation spring 12 is compressed, on the second conical section 114 and auxiliary jet inner core 13 on secondary spray group housing 11
The 4th conical section 136 fit, the second sprinkling passage closure has completely cut off into the working flow of the second flow-out hole 115, and second goes out stream
The not operation of hole 115；Part working flow enters auxiliary jet inner core 13 from leading discharge orifice 142, now, the lost effect of current compared with
Good, the working flow that the first flow-out hole 132 sprays can cover in sprinkling domain medium range to the region between shower nozzle installation site；Greatly
Part current spray from the main burner 4 of shower nozzle, the whole sprinkling domain of covering；Now, the working flow of 2 strands of distinct coverage regions is common
Effect, is capable of achieving the uniform sprinkling of shower nozzle.
Preferred embodiment but the present invention is not limited to above-mentioned implementation method to the embodiment for of the invention, not
In the case of substance of the invention, any conspicuously improved, replacement that those skilled in the art can make
Or modification belongs to protection scope of the present invention.
