Description
Technical Field
[0001] This utility model relates to the field of valves, and in particular to a valve with dual atomizing nozzles. Background Technology
[0002] To save manpower, most pesticide spraying operations are now carried out automatically by spraying systems. The multiple pipes of the spraying system are directly distributed above the work area, and each pipe used for spraying is equipped with a valve at its end. The outlet of the valve is connected to a matching atomizing nozzle. When the spraying system is running, the pesticide liquid flows through the valve to the atomizing nozzle, and is finally atomized by the atomizing nozzle and sprayed to the outside, ultimately spraying the work area to complete the pesticide spraying operation.
[0003] In actual spraying, different crops have different requirements for the atomization of the pesticide solution. However, the valves of traditional spraying systems only have a single atomizing nozzle, and the atomizing holes on the atomizing nozzle cannot be changed. Therefore, only a single atomization range and degree can be formed, resulting in a single atomization effect. If it is necessary to change the atomization effect, the atomizing nozzle must be replaced. This replacement method is extremely troublesome and consumes a lot of time, resulting in low efficiency in switching atomization effects and seriously affecting the overall spraying efficiency.

[0031] The inner wall of the outer end opening of the water delivery hole 41 is a regular hexagon.
[0032] An annular step 44 is provided on the inner wall of the outer end of the perforation 38. The upper atomizing nozzle 10 is provided on the annular step 44 of the upper perforation of the atomizing body 9, and the lower atomizing nozzle 11 is provided on the annular step 44 of the lower perforation 38 of the atomizing body 9. A limiting nut 45 is connected to both the upper and lower ends of the atomizing body 9. The upper inner wall of the upper limiting nut 45 presses against the upper surface edge of the upper atomizing nozzle 10, and the lower inner wall of the lower limiting nut 45 presses against the lower surface edge of the lower atomizing nozzle 11. A washer 46 is provided on the lower surface of the upper atomizing nozzle 10 and the upper surface of the lower atomizing nozzle 11. A speed adjustment structure is provided between the washer 46 and the step surface of the annular step 44.
[0033] The speed regulating structure is a speed regulating shim 47 located between the washer 46 and the step surface of the annular step 44; the speed regulating shim 47 is provided with a plurality of water delivery channels 48 evenly distributed in a circle; the water delivery channels 48 are arc-shaped, and the diameter of the water delivery channels 48 gradually decreases in a clockwise direction.
[0034] The speed regulating structure includes a water guide connector 49 screwed into the perforation 38; an outer tube 50 is screwed onto the water guide connector 49; a limiting nut 45 is screwed onto the end of the outer tube 50, and the inner wall of the end of the limiting nut 45 presses the upper atomizing nozzle 10 or the lower atomizing nozzle 11 and the washer 46 onto the end face of the outer tube 50; the outer wall of the end of the water guide connector 49 is provided with an annular protrusion 51 that fits against the inner wall of the outer tube 50; the outer circumferential surface of the annular protrusion 51 is provided with a plurality of spiral grooves 52 evenly distributed in a circle; the outer wall of the water guide connector 49 is provided with a plurality of water guide holes 53 that communicate with its internal space, and the water guide holes 53 are located between the spiral grooves 52 and the perforation 38.
[0035] The method of using this utility model is as follows:
[0036] The valve body 1 can be connected to the end of the pipeline of the spraying system through the water inlet connector 2. When the spraying system is turned on, the liquid medicine will enter the water inlet connector 2 through the pipeline, and then enter the groove 5 through the water outlet 7. As the liquid medicine continuously flows into the groove 5, the groove 5 is eventually filled with liquid medicine, and pushes the opening and closing plate 8 upward. When the opening and closing plate 8 moves upward, the adjusting spring 21 is compressed and generates elastic force. As the opening and closing plate 8 moves upward, the liquid medicine in the groove 5 will enter the opening and closing connector 6 through the gap between the upper end face of the opening and closing connector 6 and the lower surface of the opening and closing plate 8. Then, it will flow into the perforation 38 on the upper part of the atomizing body 9 through the water outlet connector 3, the switching hole 35, and the water supply hole in the center of the connecting shaft 39. Then, it will flow into the upper atomizing nozzle 10 through the speed-increasing effect of the speed adjustment structure. Finally, the liquid medicine is dispersed and atomized by the atomizing hole in the center of the upper atomizing nozzle 10, so that the atomized liquid medicine is sprayed out from the upper atomizing nozzle 10 to the outside for spraying operations.
[0037] Since the atomizing holes at the center of the upper atomizing nozzle 10 and the lower atomizing nozzle 11 are different, the atomization range and degree of the liquid sprayed from the upper atomizing nozzle 10 and the lower atomizing nozzle 11 are different, resulting in two different atomization effects. Therefore, different atomization effects can be obtained simply by changing different atomizing nozzles. The atomizing body 9 of this utility model has both an upper atomizing nozzle 10 and a lower atomizing nozzle 11. The switching between the upper atomizing nozzle 10 and the lower atomizing nozzle 11 can be completed simply by rotating the atomizing body 9.
[0038] When an external force is applied to the atomizing body 9 and it rotates, the limiting hole 13 of the limiting head 12 rotates synchronously. The limiting hole 13 then presses against the conical surface 33 on the limiting head 12 through its own edge. At this time, the limiting head 12 is squeezed out of the limiting hole 13 along the trajectory of the conical surface 33. The limiting spring 34 is compressed and generates elastic force, finally pressing against the right side wall of the limiting part 27. After the atomizing body 9 rotates 180 degrees, the upper atomizing nozzle 10 and the lower atomizing nozzle 11 are positioned vertically. When the limit hole 13 is replaced, the new limit hole 13 is exactly opposite to the limit head 12. At this time, the limit head 12 is pushed into the new limit hole 13 under the elastic force of the limit spring 34, completing the limit of the atomizing body 9. At this time, the switching hole 35 is connected to the lower atomizing nozzle 11. When the liquid medicine is sprayed out from the atomizing hole in the center of the lower atomizing nozzle 11, different atomization effects can be formed. When the spraying operation is completed, the opening and closing plate 8 will be reset under the elastic force of the adjusting spring 21, and the upper end port of the opening and closing connector 6 will be covered and sealed again.
[0039] In summary, this utility model has both an upper atomizing nozzle 10 and a lower atomizing nozzle 11, thus providing two different atomization effects. The switching hole 35 can only be connected to one of the upper atomizing nozzle 10 or the lower atomizing nozzle 11. Therefore, by simply rotating the atomizing body 9, the two different atomization effects can be quickly switched, effectively ensuring switching efficiency and avoiding the situation where the process of switching atomizing nozzles takes too long and affects the overall spraying efficiency.
[0040] Since the regulating cover 14 is screwed onto the outside of the boss 4, the regulating cover 14 can be moved up and down simply by rotating it. When the opening and closing plate 8 is restricted from moving down by the opening and closing joint 6, the regulating spring 21 is compressed to a greater extent when the regulating cover 14 moves down. At this time, the initial elastic force of the regulating spring 21 is greater, so a greater force is required when the opening and closing plate 8 is pushed up. When the liquid pressure remains unchanged, the gap between the lower surface of the opening and closing plate 8 and the upper end surface of the opening and closing joint 6 becomes smaller, thereby controlling the flow rate of the liquid entering the opening and closing joint 6, and finally achieving the effect of regulating the flow rate through the regulating structure.
[0041] The upper surface of the movable seat 18 is provided with an annular positioning groove 23. The lower end of the adjusting spring 21 is embedded in the positioning groove 23. The presence of the positioning groove 23 can effectively ensure the stability of the lower end of the adjusting spring 21, thereby ensuring the stability of the adjusting spring 21 when it is compressed or opened, which is conducive to the up and down movement of the opening and closing plate 8. The center of the upper surface of the movable seat 18 is provided with a guide rod 24 that matches the guide tube 17. The presence of the guide rod 24 has a guiding function, further ensuring the stability of the opening and closing plate 8 when it moves up and down.
[0042] The outer right wall of the water outlet connector 3 is provided with an annular sealing step 42. There are sealing rings 43 fitted around the water outlet connector 3 between the sealing step 42 and the right end face of the rotating sleeve 36, and between the left end face of the rotating sleeve 36 and the right side wall of the sealing part 28. The presence of the sealing rings 43 can effectively ensure the sealing between the sealing step 42 and the right end face of the rotating sleeve 36, and between the left end face of the rotating sleeve 36 and the right side wall of the sealing part 28, thereby effectively ensuring the sealing of the left and right ends of the rotating hole 26 and preventing water leakage.
[0043] The inner wall of the outer end of the water supply hole 41 is hexagonal. By inserting one end of the Allen wrench into the upper end of the water supply hole 41, the connecting shaft 39 can be easily rotated to complete the quick assembly and disassembly of the connecting shaft 39.
[0044] When it is necessary to disassemble the upper atomizing nozzle 10 and the lower atomizing nozzle 11, simply unscrew the limiting nut 45 screwed to the end of the atomizing body 9, and the upper atomizing nozzle 10 and the lower atomizing nozzle 11 can be taken out from the annular step inside the hole 38 on the wall.
[0045] The speed control structure is a speed control shim 47 located between the washer 46 and the step surface of the annular step 44. The speed control shim 47 is provided with several water delivery channels 48 evenly distributed in a circle. When the liquid medicine is to flow to the upper atomizing nozzle 10 or the lower atomizing nozzle 11, the liquid medicine will inevitably pass through the water delivery channel 48. The water delivery channel 48 is arc-shaped, and the diameter of the water delivery channel 48 gradually decreases in the clockwise direction. The continuously narrowing diameter can effectively increase the flow rate of the liquid medicine, thereby effectively improving the atomization effect of the upper atomizing nozzle 10 and the lower atomizing nozzle 11.
[0046] The speed-regulating structure includes a water guide connector 49 screwed into the perforation 38, an outer tube 50 screwed onto the outside of the water guide connector 49, and a limiting nut 45 screwed onto the end of the outer tube 50. The inner wall of the end of the limiting nut 45 presses the upper atomizing nozzle 10 or the lower atomizing nozzle 11 and the washer 46 against the end face of the outer tube 50. The outer wall of the end of the water guide connector 49 is provided with an annular protrusion 51 that fits against the inner wall of the outer tube 50. The outer circumferential surface of the annular protrusion 51 is provided with several spiral grooves 52 evenly distributed in a circle. The outer wall of the water guide connector 49 is provided with several water guide holes 53 that communicate with its internal space. The water guide holes 53 are located between the spiral grooves 52 and the perforation 38. When the liquid medicine flows through... After passing through the water inlet 41 at the center of the connecting shaft 39, the liquid will flow directly into the water guide connector 49, and then through the water guide hole 53 into the gap between the outer wall of the water guide connector 49 and the inner wall of the outer tube 50. Under the obstruction of the annular protrusion 51, the liquid can only flow through the spiral groove 52 to the upper atomizing nozzle 10 and the lower atomizing nozzle 11. The spiral groove 52 is not only spiral-shaped, but also has a uniformly distributed annular protrusion 51 on its outer circumference. Therefore, under the guidance of the inner wall of the spiral groove 52, the liquid can form a spiral fluid, which significantly improves the liquid flow rate and ultimately effectively improves the atomization effect of the upper atomizing nozzle 10 and the lower atomizing nozzle 11.
