Interruption-rotating water granulation device

Abstract

The invention belongs to a fluid control device, and particularly relates to an interruption-rotating water granulation device of a reaction-type spraying nozzle. The interruption-rotating water granulation device is mainly composed of a damping sleeve, a spraying disk, a water distributing disk, a center shaft, a fixing gear disk and a supporting frame, wherein water distributing teeth are arranged on the outer side of the water distributing disk, and meshing teeth are arranged on the inner side of the water distributing disk. When the spraying nozzle works, a jetting flow impacts the water distributing teeth, and therefore the jetting flow is broken, short-jetting-range spraying is achieved, when the jetting flow deviates from the water distributing teeth, long-jetting-range spraying is achieved, the meshing teeth and upper teeth on the fixing gear disk interact, and interruption rotating of the water distributing disk is achieved. Through mutual matching of the spraying disk, the water distributing disk and the fixing gear disk, breakage of the jetting flow and the interruption rotating are achieved, finally, overlapping of the long jetting range and the short jetting range in different angles is achieved, and water amount distribution of the spraying nozzle under the low-pressure work condition is improved. The interruption-rotating water granulation device is simple in structure, reliable in operation, stable in working, and capable of improving distribution of the water amount of the spraying nozzle and improving spraying evenness under the condition that the jetting range is not reduced.

Description

technical field [0001] The invention relates to an intermittent rotary water crushing device, which is suitable for rotary sprinklers with low working pressure and long range, in particular to the intermittent rotary water crushing device for reaction sprinklers. Background technique [0002] The sprinkler head is the key equipment to realize sprinkler irrigation, and one of the ways to reduce the energy consumption of the sprinkler irrigation system is to reduce the working pressure of the sprinkler head. As the working pressure of the sprinkler head decreases, the hydraulic performance of the sprinkler head will often be reduced, resulting in a decrease in the irrigation quality of the irrigation system. In order to improve the irrigation quality of the nozzle, many scholars have proposed a variety of solutions, which can be summarized as follows: 1. Special-shaped nozzles; 2. Multiple jets; 3. Adding auxiliary water crushing mechanisms. The special-shaped nozzle is mainl...
