Problems solved by technology

[0004] In order to overcome the lack of uneven water distribution of existing nozzles, the present invention provides an asymmetric uniform water distribution nozzle, which can change the continuous water flow in the pipeline into fine water droplets, which can be evenly sprayed to a certain range on the ground to achieve a reasonable water distribution. , and the sprinkling intensity is appropriate, the sprinkler head itself has a simple structure, reliable operation, and good hydraulic performance

Embodiment Construction

[0015] The present invention is composed of several nozzles 2 installed on a nozzle 1, each nozzle 2 works independently and does not affect each other, each nozzle is equipped with a resistance net with different local resistance, and the distribution of the nozzles on the nozzle is spiral ( Such as figure 1 ), the elevation angle α of nozzle 2 is different. Further illustrate the present invention by implementing example below:

[0016] Working water head with nozzle h p =10m, take 20 nozzles as an example. The local resistance head formed by the resistance network is h i , the range of the nozzle is R, and the elevation angle of the nozzle is α, regardless of the height of the nozzle from the ground. The nozzle number is 1 from the top of the nozzle downwards # ,2 # 、3 # ,...,20 # , when the nozzle does not rotate, the theoretical calculation is as follows:

[0017] 1 # alpha 1 =30° h i1 =0.0m d 1 =4.0mm then V 1 =14.0m / sR 1 =17.3mQ 1 =0.63m 3 / h

Abstract

An asymmetrical sprinkler head for uniformly distributing water features that it has multiple nozzles arranged spirally on it and with different spray distances.

Description

technical field [0001] The present invention relates to the spray head in the composition of the sprinkler irrigation system, specifically, it is the spray head for irrigation that sprays the continuous water flow in the pipeline into the air, breaks it into fine water droplets, and evenly lands on a certain range. Background technique [0002] The sprinkler head is the main component of the sprinkler irrigation system. A good sprinkler head should not only have good mechanical properties, that is, simple structure and reliable operation, but also require good hydraulic performance and energy saving. However, these requirements are often contradictory or restrict each other. [0003] The spraying range of single-nozzle nozzles is limited, and the distribution of water volume is difficult to achieve uniform distribution. At present, multi-nozzle sprinklers in sprinkler irrigation are in use because the nozzle pressure is the same, and the range and flow rate of each nozzle are...
