Abstract
An injecting body of the injector is provided with two outlets. One outlet is connected to an auxiliary nozzle in a threaded manner, and the other outlet is connected to an injecting element body in a threaded manner. The water taking signal nozzle circularly takes signal water and air conveniently and reliably, so that a low-pressure vortex region is discontinuously formed at one side of the injecting element body; formation and disappearance of a pressure difference between a left cavity and a right cavity can be implemented in an automatic control manner, and wall attachment of water and rotation of the injector are implemented. The auxiliary nozzle is primarily used for supplementing near water distribution of the double-nozzle injector capable of spraying at a medium and low pressure, so as to improve spraying evenness.
