Description
1, technical field:
The utility model relates to a kind of shower nozzle of sprinkler, relates in particular to a kind of wind resistance shower nozzle of sprinkler.
2, background technology:
Sprinkler is to enhance productivity in plants and flowers and vegetable melon and fruit plantation, carry out scientific application of irrigation, the necessaries of conserve water resource and cost of labor, shower nozzle is the vitals of sprinkler, traditional shower nozzle, the range of its water spray is to decide according to the hydraulic pressure in the water route of sprinkler, and shower nozzle self can not adjust, run into wind is arranged in, the water spraying direction difference of each nozzle of same shower nozzle, be subjected to the influence of wind-force, the range of the nozzle water spray of all directions is all inequality, some shortens, also some is elongated, therefore the part plant can occur does not water water, water is sprayed onto non-planting site face phenomenon, thus normal growth of the plant of influence and the waste that causes the water source.
The windproof shower nozzle has appearred in recent years, for example Granted publication number discloses a kind of reaction type self adaptation wind resistance spray irrigation economize shower nozzle for the Chinese utility model patent specification of CN2709017Y, it is by head body, nozzle boss, articulating device, wind sensible plate, bascule and amplitude adjustment control device are formed, head body and nozzle boss are hinged on the bearing, when wind is arranged, it drives head body by wind sensible plate and swings certain angle to offset the influence of wind-force to the nozzle range along bearing, but still there is following shortcoming in it: 1) whole head body is swung when wind is arranged, the difficult control of its amplitude of oscillation, when the wind direction not timing, the adjustment that is flapped toward that head body is difficult to make, and can make head body generation axial deflection, the accuracy of influence water spray, reliability is not high enough; 2) this amplitude adjustment control device is a kind of device with learning functionality, needs manual adjustment when having wind to spray, and uses comparatively trouble; 3) when installing and using, need make the bearing of its swing for the head body setting, structure is comparatively complicated, has increased the difficulty of watering system integral layout;
4) during big or blast, cause head body to damage when wind-force easily.
3, summary of the invention:
In order to overcome the deficiencies in the prior art, the purpose of this utility model provides a kind of wind resistance shower nozzle of sprinkler.
The utility model is achieved by the following technical solution: it comprises head body and wind direction wind-force induction installation, head body is provided with water inlet and some nozzles with a plurality of water spraying directions, between water inlet and each nozzle, be provided with flow control valve, flow control valve is provided with and can distributes the spool of regulating each water discharge nozzle, wind direction wind-force induction installation is subjected to wind-force rotating band movable valve plug that the discharge of the reverse nozzle of water spraying direction and wind direction is increased, and the discharge of water spraying direction and wind direction nozzle forward reduces.At gentle breeze or do not have under the state of wind, each nozzle on the head body is in a normal spray regime, when wind, respond to wind direction and wind-force in real time by wind direction wind-force induction installation, the spool occurrence positions that wind direction wind-force induction installation drives flow control valve changes, and the discharge with the reverse nozzle of wind direction is increased, thereby this nozzle water spray pressure is increased, it is big that the distance of spraying becomes relatively, but because the acting in opposition of wind-force, the distance of injection diminishes relatively; Discharge with wind direction nozzle forward reduces simultaneously, thereby this nozzle water spray pressure is reduced, jet length diminishes, but be subjected to the positive acting of wind-force, the distance of its injection obtains increasing relatively, this shows the range that changes nozzle by the big I of current that changes nozzle, offset the influence of wind-force, the range of the nozzle water spray of all directions is kept and original scope substantially.Described reverse or down wind be comprise over against with two kinds of deflections, over against amplitude of accommodation maximum, then decide of deflection on the deflection angle, under same angle, it is big more to be partial to angle, the amplitude of adjusting can be more little.The displacement of spool is corresponding with wind-force, can adjust according to the variation of wind-force, reduces the influence of wind-force to the shower nozzle water spray effectively, and can regulate automatically, and is without manually-operated, easy to use.
Such scheme can be further improved by following measure:
