Abstract
The utility model provides an energy saving double rectangular nozzle with a flow channel at the front which is formed by two parallel rectangular holes, and each rectangle appropriate length ratio, i.e. b/a is lower than 5, while the sum, i.e. 2a plus c of the distance c between two rectangles and the width a between two rectangles is lower than 10mm. Working under the double rectangular nozzle pressure lower than that of the prior round nozzle, the utility model achieves the same atomization level with the round nozzle, consequently reducing the system energy consumption. On condition of keeping the similar diameters of the jet current end drops of the two, the working pressure of the utility model nozzle reduces by more than 16.7 to 28.6 percent than the round nozzle, and under the same working pressure, the end drop diameter can be reduced, thereby applying to the rotary arm nozzle. The energy saving nozzle of the utility model is good for the application of the spray irrigation technology.
Description
Technical field
The utility model relates to a kind of sprinkling irrigation equipment, especially a kind ofly is installed in sprinkling irrigation with the double square nozzle on the shower nozzle.
Background technology
In field irrigation, sprinkler irrigation technique is used in water-saving irrigation always, and it is by after the water pump pressurization, and water is sprayed by shower nozzle atomizing back.Nozzle is a vitals of shower nozzle, and traditional nozzle is continued to use round nozzle always, and its nozzle flow channel is a gradual change type, and the gradual change angle of gradual change runner is bigger, usually about 45 °.The key factor that the sprinkling irrigation development is restricted is that energy consumption is higher, when sprinkling irrigation, in order to make the nozzle end water droplet little, does not smash crop, and this just needs the pressure height, but can increase energy consumption.Thereby, be an importance of development sprinkler irrigation technique to the improvement of nozzle form and structure.
The utility model content
Need bigger operating pressure in order to overcome existing round nozzle, make the higher deficiency of energy consumption, the utility model provides a kind of energy-saving double square nozzle, and this double square nozzle can reduce operating pressure, thereby reduces the energy consumption of system.
The technical scheme that its technical problem that solves the utility model adopts is as follows:
A kind of energy-saving double square nozzle, there is a longitudinal hole in portion within it, is nozzle flow channel, and the rear portion of this nozzle and the jet pipe of shower nozzle are by being threaded.In the front portion of nozzle, described nozzle flow channel is two rectangular openings side by side, and the width a sum 2a+c of the distance c between suitable length-width ratio b/a＜5, two rectangle of each rectangle and two rectangles is less than 10 millimeters.
The beneficial effects of the utility model are: when the utility model double square nozzle is worked, reach the fogging degree identical with existing round nozzle under than the low pressure of existing round nozzle, thereby reduce the energy consumption of system.
The results showed:
When 1, keeping the terminal drop diameter of jet close, the comparable existing round nozzle of the operating pressure of the utility model double square nozzle reduces about 98kPa, and pressure reduces percentage more than 16.7%～28.6%.
2, under the same operating pressure, the terminal drop diameter of the utility model double square nozzle reduces 0.67～0.97mm than existing round nozzle.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Illustrated in figures 1 and 2 is an embodiment of the energy-saving double square nozzle of the utility model, and this double square nozzle interior has a longitudinal hole, is nozzle flow channel 1.The rear portion of this nozzle and the jet pipe of shower nozzle are by being threaded, and in the front portion of nozzle, this nozzle flow channel 1 is two rectangular openings 2 side by side.Can be the taper hole that an aperture forward end diminishes gradually in the stage casing of nozzle flow channel, form gradual change angle θ.The utility model will realize reducing operating pressure, and important design parameter is the length-width ratio b/a of gradual change angle θ, rectangle and the distance c between two rectangles.The results showed that gradual change angle θ is to sprinkler pattern range, single shower nozzle water distribution and not obvious in the influence of the maximum drop diameter of jet end,, can get θ=0 ° in order to simplify nozzle arrangements.Distance c between the length-width ratio b/a of each rectangle, two rectangles all has a significant effect to sprinkler pattern range and maximum drop diameter, and linearity reduces with the increase of c value, but the c value also has a significant effect to the shower nozzle velocity of rotation.In order to guarantee the shower nozzle normal rotation, and obtain range far away, the suitable length-width ratio b/a of rectangle should be advisable to be no more than 10 millimeters less than the width a sum 2a+c of the distance c between 5, two rectangles and two rectangles.
The utility model is applicable to impact driven sprinkler.Jet pipe 4 with the rear portion of the utility model nozzle 3 and shower nozzle shown in Figure 3 is connected by screw thread in use, the jet that comes out from shower nozzle penetrates from the nozzle double rectangle hole by direction shown in the arrow Fig. 1, impact the water fender 5 on the rocking arm 6 that forwards nozzle the place ahead to this moment, impulsive force makes rocking arm 6 opened with certain angle, and priming lever spring 7 is tightened up.When priming lever spring 7 resetted, rocking arm 6 returns, bump head cartridge, its reaction force drove shower nozzle drive nozzle and turn an angle, and so move in circles, and the crop all around in the nozzle range is all irrigated.
Claims (3)
1, a kind of energy-saving double square nozzle, there is a longitudinal hole in portion within it, be nozzle flow channel, the rear portion of this nozzle and the jet pipe of shower nozzle are by being threaded, it is characterized in that: in the front portion of nozzle, described nozzle flow channel is two rectangular openings side by side, and the width a sum 2a+c of the distance c between suitable length-width ratio b/a＜5, two rectangle of each rectangle and two rectangles is less than 10 millimeters.
