Abstract
The invention discloses a centrifugal spray head with annular grooves for a landscaping project. The centrifugal spray head comprises a liquid inlet tube and a spray head body, wherein a liquid inlet flow channel is formed in the liquid inlet tube; a swirl chamber is formed in the spray head body; a tapered spray head core is arranged in the swirl chamber; a plurality of annular grooves are formed in the spray head core; a spray head piece is arranged at the upper part of the spray head body; a spray head hole is formed in the spray head piece; and a spray head cap is arranged at the upper part of the spray head piece. Compared with a conventional spray head, the centrifugal spray head has the advantages that a plurality of annular grooves are formed in the spray head core, so that the medicinal liquid is enabled to continuously collide with the annular grooves during the helical motion process, the motion of the molecules in the medicinal liquid is activated, and the fogdrops formed after the medicinal liquid is sprayed further collide with the relatively rest air to form smaller fogdrops; therefore, through the adoption of the spray head, under the condition that the medicine spraying amount is the same, the diameter of the fogdrops is smaller, the number of the fogdrops is larger, the cover area of the medicinal liquid is large and uniform, the lost medicinal liquid is few, and the prevention and control effect is good.
Description
Technical field
The present invention relates to shower nozzle, being specially a kind of centrifugal sprinkler for having cannelure in landscape engineering.
Background technology
Along with the fast development of urban construction, also improve constantly the requirement of afforestation, Garden Greening Work be unable to do without the instrument of specialty, and it fully can replace manual labor, saves time, and operating efficiency is high.The plant such as trees and flowers of afforestation in growth course, inevitably will be subject to the harm of various Pest organism, therefore in order to make the plant such as trees and flowers can have a good growing environment, need regular to carry out spray liquid to eliminate Pest organism to it, sprayer is then a kind of the most frequently used instrument.
When sprayer carries out medicine liquid spray, the prevention effect that sprinkler performance quality will directly have influence on diseases and pests of agronomic crop, when spray value is identical, the diameter of droplet is less, and the number of droplet is also more, and the area coverage of liquid is large and even, the loss of liquid is few, and prevention effect is good.And there is medical liquid atomizing diameter slightly more in the shower nozzle of the sprayer used at present, the problem of spray effect difference.
Summary of the invention
The invention is intended to provide a kind of centrifugal sprinkler for having cannelure in landscape engineering, the problem of the spray effect difference slightly caused with the atomization diameter solving liquid.
The centrifugal sprinkler for having cannelure in landscape engineering in this programme, comprise feed tube and sprayer body, feed tube place is provided with feed liquor runner, and sprayer body is provided with minor air cell, and minor air cell communicates with feed liquor runner, the sprinkler core of band tapering is provided with in minor air cell, sprinkler core is provided with some cannelures, and the top of sprayer body is provided with ozzle disc, ozzle disc offers shower nozzle hole, ozzle disc top is also provided with sprinkler cap, and sprinkler cap is threaded with sprayer body.
The principle of this programme is: sprayer work makes, liquid enters minor air cell from the feed liquor runner of feed tube, the sprinkler core of strip winding tapering is done high-speed screw motion by the liquid entered in minor air cell, liquid will ceaselessly collide with the cannelure on sprinkler core while doing high-speed screw motion, through the shower nozzle hole place of the liquid arrival ozzle disc of some cannelure collision rift, because the radius of gyration of liquid reduces gradually, therefore the peripheral speed of liquid will increase gradually, when liquid arrives the shower nozzle hole place on ozzle disc, the direction of motion and the shower nozzle centerline hole of liquid reality have certain angle, this angle is the atomizing angle of shower nozzle, liquid is after the ejection of shower nozzle hole, the dispersion shape film with tapering will be become, the film far away apart from shower nozzle hole is thinner so that fragment into fragment, and then be condensed into droplet, due to liquid in minor air cell with the collision of cannelure through several times, therefore the molecule activity aggravation in liquid, therefore will the droplet of more minor diameter be formed when the droplet of liquid ejection formation and the air of geo-stationary collide further, and then be sprayed onto on the plant that needs to carry out the prevention and control of plant diseases, pest control.
This programme is compared with transmission shower nozzle, by arranging some annular grooves on sprinkler core, liquid is ceaselessly collided in the process of screw with cannelure, thus the molecular motion in aggravation liquid, when the droplet of liquid ejection formation and the air of geo-stationary collide further, can form less droplet, therefore adopt this shower nozzle can when spray value is identical, the diameter of droplet be little, the number of droplet is many, the area coverage of liquid is large and evenly, the loss of liquid is few, and prevention effect is good.
Further, the fogdrop diameter formed to make liquid reduces further, and shower nozzle hole is arc-shaped structure towards sprinkler cap side.
Further, in order to prevent liquid from leaking from sprayer body and ozzle disc, between sprayer body and ozzle disc, being provided with gasket seal, considering that a lot of liquid is chemical substance and has very strong corrosivity simultaneously, in order to improve the resistance to corrosion of gasket seal, gasket seal is Viton gasket seal.
Further, feed liquor runner is pyramidal structure, and feed liquor runner and joint, minor air cell are the small end of pyramidal structure, and when liquid enters minor air cell through feed liquor runner, the feed liquor runner of pyramidal structure can improve the speed that liquid enters minor air cell along with the reduction of sectional dimension.
