Abstract
The utility model provides a flow channel gradual transition energy saving triangular nozzle, whose gradual transition flow channel has a gradual transition angle between 25 degree to 35 degrees, and the flow channel at the nozzle front is a triangular hole whose height and width ration, i.e. H/L is from 0.9 to 1.0. When working under the pressure lower than that of the prior round nozzle, the triangular nozzle of the utility model achieves the same atomization level with the prior 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 triangular 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 the gradual change angle of its gradual change runner is also 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 flow passage gradual change formula energy-saving triangular nozzle, and this triangular 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:
The energy-saving triangular nozzle of a kind of flow passage gradual change formula, there is a longitudinal hole in portion within it, is nozzle flow channel, and the stage casing of this runner is the taper hole that an aperture forward end diminishes gradually, forms gradual change angle θ, and the rear portion of this nozzle and the jet pipe of shower nozzle are by being threaded.Described gradual change angle θ=25 °～35 °; In the front portion of nozzle, described nozzle flow channel is tri-angle-holed, and this leg-of-mutton depth-width ratio H/L is 0.9～1.0.
The beneficial effects of the utility model are: when the utility model triangular 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 keeping the terminal drop diameter of jet close, the comparable round nozzle of the operating pressure of the utility model triangular nozzle reduces about 98kPa, and pressure reduces percentage 16.7%～28.6%.

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 triangular nozzle of the utility model flow passage gradual change formula, and there is a longitudinal hole this triangular nozzle inside, is nozzle flow channel 1, and the stage casing of this runner is the taper hole that an aperture forward end diminishes gradually, forms gradual change angle θ.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 tri-angle-holed 2.The utility model will realize reducing operating pressure, and important design parameter is gradual change angle θ and leg-of-mutton depth-width ratio H/L.Wherein the θ angle is to sprinkler pattern range, single shower nozzle water distribution and obvious in the influence of the maximum drop diameter of jet end, and this gradual change angle θ can be 25 °～35 °, wherein preferable gradual change angle θ=30 °.And leg-of-mutton depth-width ratio H/L can be 0.9～1.0, is suitable depth-width ratio with H/L=1.0 wherein, and this moment, single water distribution was best.
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 nozzle tri-angle-holed 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.
