Description
Technical Field
The invention belongs to the technical field of water-saving irrigation devices, and relates to a special-shaped nozzle for spray irrigation.
background
At present, the water efficiency of agricultural irrigation is low, the waste of water resources is serious, the agricultural water is further lacked, and the rapid development of water-saving irrigation is the most fundamental means for solving the shortage of agricultural water in China. The nozzle is one of important components in a sprinkler irrigation system, is widely applied to crop irrigation, but has the defects that the water outlet speed of the nozzle section is not uniformly distributed, the water quantity distribution near the nozzle is less, and the water quantity distribution in the nozzle is more in a long distance in the application process.
Disclosure of Invention
the invention aims to provide a special-shaped nozzle for sprinkling irrigation, which solves the problems that the water outlet speed of the nozzle section is not uniformly distributed, the water quantity distribution near a nozzle is less, and the long-distance water quantity distribution in the nozzle is more in the prior art.
The invention adopts the technical scheme that the special-shaped nozzle for spray irrigation comprises a nozzle body, wherein the top of the nozzle body is in a round table shape, and the bottom of the nozzle body is in a cylindrical shape; the nozzle body is hollow, a cylindrical part at the bottom in the nozzle body is provided with threads, and a circular truncated cone-shaped part at the top in the nozzle body is provided with a curved flow passage.
The invention is also characterized in that:
2-4 curved runners are arranged at intervals along the periphery of the inner wall of the circular truncated cone-shaped part;
The curved flow passage is S-shaped;
The curved runner is C-shaped;
The curvature radius of the curved flow passage is 2/7 of the inner diameter of the nozzle;
the cross section of the curved flow channel is semicircular, and the radius of the semicircular cross section is 1/7 of the inner diameter of the water outlet of the special-shaped nozzle;
The curved flow passage extends from the top end of the nozzle body to the cylindrical connection part at the bottom.
The invention has the beneficial effects that:
When the water flow is in work, the water flow line flowing through the curved flow channel is bent when the water flow passes through the nozzle, a vortex body is formed between the water flow close to the inner side wall of the nozzle and the water flow near the axis of the nozzle, and particles in the water body are mixed and collided with each other, so that the water flow speed close to the inner side wall of the nozzle is improved, and the speed of the water flow near the axis of the nozzle is reduced; the S-shaped or C-shaped curved flow channel can increase the number of vortexes, so that more energy exchange occurs between water flow close to the inner side wall of the nozzle and water flow near the axis of the nozzle, invalid capability collision loss is reduced, a core flow velocity area of jet flow cannot be damaged, the water outlet speed distribution of an outlet section is more uniform, the water distribution near the nozzle is increased, and medium and long distance water distribution is reduced; the whole spray head has simple structure, low cost, stable performance and good hydraulic performance.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
In the embodiment, as shown in fig. 1-3, a special-shaped nozzle for sprinkling irrigation comprises a nozzle body, wherein the top of the nozzle body is in a circular truncated cone shape, and the bottom of the nozzle body is in a cylindrical shape; the nozzle body is hollow inside, water flows through the nozzle body, the cylindrical part at the bottom in the nozzle body is provided with threads 2 and is connected with the spray head through the threads 2, the nozzle is convenient, quick and easy to detach, the circular truncated cone-shaped part at the top in the nozzle body is provided with a curved flow channel 1, and a vortex body is formed between water flow on the inner side wall of the adjusting nozzle and water flow near the axis of the nozzle.
2-4 curved flow channels 1 are arranged at intervals along the periphery of the inner wall of the circular truncated cone-shaped part, and in the embodiment, as shown in fig. 3, 3 curved flow channels 1 are arranged.
The curved runner 1 is S-shaped.
the curved runner 1 is C-shaped.
the curvature radius of the curved flow passage 1 is 2/7 of the inner diameter of the nozzle.
The cross section of the curved flow channel 1 is semicircular, and the radius of the semicircular cross section is 1/7 of the inner diameter of the water outlet of the special-shaped nozzle.
The curved runner 1 extends from the top end of the nozzle body to the cylindrical connection part at the bottom.
the working principle of the invention is as follows:
when the water flow is in work, the water flow line flowing through the curved flow channel is bent when the water flow passes through the nozzle, a vortex body is formed between the water flow close to the inner side wall of the nozzle and the water flow near the axis of the nozzle, and particles in the water body are mixed and collided with each other, so that the water flow speed close to the inner side wall of the nozzle is improved, and the speed of the water flow near the axis of the nozzle is reduced; the S-shaped or C-shaped curved flow channel can increase the number of vortexes, so that more energy exchange can be carried out between water flow close to the inner side wall of the nozzle and water flow near the axis of the nozzle, invalid capacity collision loss is reduced, a core flow velocity area of jet flow can not be damaged, the water outlet speed distribution of the outlet section is more uniform, the water distribution near the nozzle is increased, and the remote water distribution is reduced.
