Abstract
The utility model relates to a passageway gradual changing type energy saving square jet nozzle, wherein, a gradual changing angle of a gradual changing passageway is 25 degrees to 35 degrees and a passageway at the front of the jet nozzle takes the shape of a square hole. The utility model is characterized in that: when the square jet nozzle works on a pressure lower than a working pressure of a current round jet nozzle, a fogging degree which is the same as the round jet nozzle can be reached, thus the energy consumption is reduced; when the square jet nozzle and the round jet nozzle has a similar drop diameter of water jet end, the working pressure of the utility model can be 16.7 percent to 28.6 percent lower than the round jet nozzle, and the drop diameter of water jet end can be reduced when the square and round jet nozzles are under the same working pressure. The utility model is applicable to impact driven sprinklers. The energy saving jet nozzle of the utility model contributes to the application of sprinkling 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 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 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 square nozzle, and this 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:
The energy-saving square 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 a square opening.
The beneficial effects of the utility model are: when the utility model 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 round nozzle of the operating pressure of the utility model square nozzle reduces about 98kPa, and pressure reduces percentage 16.7%～28.6%;
2, under the same operating pressure, the terminal drop diameter of the utility model square nozzle reduces 0.73～0.96mm than 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 square nozzle of the utility model flow passage gradual change formula, there is a longitudinal hole this square nozzle inside, be nozzle flow channel 1, the stage casing of this runner is the taper hole that an aperture forward end diminishes gradually, form gradual change angle θ, this gradual change angle θ can be 25 °～35 °, wherein preferable gradual change angle θ=30 °, this moment, sprinkler pattern range reduced minimum than round nozzle, and is also less at the maximum drop diameter of jet end.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 a square opening 2.
The utility model is applicable to impact driven sprinkler.Jet pipe 4 with the rear portion of the utility model nozzle 3 and impact driven sprinkler shown in Figure 3 is connected by screw thread in use, the jet that comes out from shower nozzle penetrates from the square hole of nozzle 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 (2)
1, the energy-saving square nozzle of a kind of flow passage gradual change formula, there is a longitudinal hole in portion within it, be nozzle flow channel, the stage casing of this runner is the taper hole that an aperture forward end diminishes gradually, form gradual change angle θ, the rear portion of this nozzle and the jet pipe of shower nozzle is characterized in that: described gradual change angle θ=25 °～35 ° by being threaded, in the front portion of nozzle, described nozzle flow channel is a square opening.
2, the energy-saving square nozzle of flow passage gradual change formula according to claim 1 is characterized in that: described preferable gradual change angle θ=30 °.
