Summary of the invention
The purpose of this utility model provides a kind of simple in structure, cheap, the nozzle component that droplet size is consistent, spray evenly and have the antidrip function.
The technical solution of the utility model is: a kind of voltage stabilizing nozzle component, comprise spray sheet, filter screen, sprinkler cap, sprayer body, gland, spring, spring base, diaphragm, stop screw, it is characterized in that: described sprayer body is provided with storage and presses the chamber, storage presses the outer end, chamber to be provided with the screw thread that mates with sprinkler cap, sprayer body is provided with annular chamber, the annular chamber outer end is provided with the screw thread with the gland coupling, sprayer body is provided with the ring muscle, ring muscle inboard is provided with guiding rib, sprayer body is provided with intake antrum, and the intake antrum inboard is provided with the sealing inclined-plane.
Described gland is provided with the spring base installing hole.
Described spring base one end is provided with the draw ring hole, and an end is provided with diaphragm, is provided with diaphragm one end and is provided with the screw thread that mates with stop screw, is provided with spring between spring base and the gland.
Described stop screw mounts elastically by screw thread, and the stop screw end is provided with and seals the sealing strip of inclined-plane coupling.
Described draw ring is installed on the draw ring hole of spring base.
Be provided with filter screen and spray sheet in the described sprinkler cap.
Spring is used for controlling the minimum operating pressure of nozzle component, and spring can be determined its flexible size according to the difference of required pressure.
Stop screw is used for controlling the nozzle component maximum working pressure, and stop screw adopts resistant material to make.
Spray sheet described in the utility model has convertibility, to satisfy different needs of work.Has pressure stabilization function simultaneously, atomizing effect unanimity in the time that work can being guaranteed.
The beneficial effects of the utility model are: this nozzle component passes through such scheme, can effectively control operating pressure at sprinkler, keep the atomizing effect unanimity, simultaneously simple in structure, easy to use, need not professional training, be specially adapted to the peasant and use knapsack hand sprayer to carry out prevention and control of plant diseases, pest control process.
Description of drawings
This figure is the utility model voltage stabilizing nozzle component structural representation;
Sequence number explanation: 1 spray sheet; 2 filter screens; 3 sprinkler caps; 4 sprayer bodies; The chamber is pressed in 5 storages; 6 draw rings; 7 draw ring holes; 8 spring bases; 9 glands; 10 springs; 11 screw threads; 12 diaphragms; 13 ring muscle; 14 steps; 15 annular chambers; 16 guiding ribs; 17 stop screws; 18 intake antrums; 19 sealing strips; 20 sealing inclined-planes.
The specific embodiment
With reference to the nozzle component of voltage stabilizing shown in the accompanying drawing, comprise spray sheet 1, filter screen 2, sprinkler cap 3, sprayer body 4, chamber 5 is pressed in storage, draw ring 6, draw ring hole 7, spring base 8, gland 9, spring 10, screw thread 11, diaphragm 12, ring muscle 13, step 14, annular chamber 15, guiding rib 16, stop screw 17, intake antrum 18, sealing strip 19, sealing surface 20, sprayer body 4 is provided with storage and presses chamber 5, and storage presses 5 outer ends, chamber to be provided with filter screen 2, and the filter screen outer end is provided with spray sheet 1, filter screen 2 spray sheets 1 are fixed on through being threaded on the sprayer body 4 by sprinkler cap 3, and spring base 8 lower ends are provided with diaphragm 12, and spring base 8 is provided with spring 10, the spring base 8 outer glands 9 that are provided with, gland 9 is installed to by being threaded on the sprayer body 4, and spring base 8 is provided with draw ring hole 7, and draw ring 6 is installed on the draw ring hole 7, stop screw 17 is fixed on the spring base by screw thread 11, and stop screw 17 ends are provided with sealing strip 19.
Operation principle: liquid enters nozzle component through intake antrum 18, enter the cavity of 16 of guiding ribs by the gap on sealing strip 19 and 20 on inclined-plane of sealing, when fluid pressure is increased to greater than minimum operating pressure, the active force that fluid pressure produces diaphragm 12 is greater than the active force of 10 pairs of spring bases 8 of spring, diaphragm 12 is to the motion of compression spring 10 directions, diaphragm 12 breaks away from ring muscle 13, liquid enters storage and presses chamber 5 after the gap between diaphragm 12 and the ring muscle 13 enters annular chamber 15, final liquid arrives spray sheet 1 through filter screen 2, forming atomized spray through spray sheet 1 goes out, diaphragm 12 continues to the motion of compression spring 10 directions when fluid pressure is greater than maximum working pressure in the intake antrum 18, sealing strip 19 on the stop screw 17 contacts with sealing inclined-plane 20, liquid in the intake antrum 18 no longer continues to enter the cavity of 16 of guiding ribs, storage is pressed the liquid in the chamber to continue to form atomized spray through spray sheet 1 and is gone out, when the fluid pressure in chamber 5 is pressed in storage is lower than maximum working pressure (MWP), the active force that liquid produces diaphragm 12 is lower than the active force of 10 pairs of spring bases 8 of spring, spring base 8 is to the direction motion of pull-off spring 10, sealing strip 19 on the stop screw 17 breaks away from sealing inclined-plane 20, liquid in the intake antrum 18 continues to enter, storage presses chamber 5 internal pressures to keep the operating pressure state, thereby reaches the even purpose of atomizing.
