DOUBLE-NOZZLE INJECTOR CAPABLE OF SPRAYING EVENLY AT MEDIUM AND LOW PRESSURE

摘要

A double-nozzle injector capable of spraying evenly at a medium and low pressure. An injecting body of the injector is provided with two outlets. One outlet is connected to an auxiliary nozzle (1) in a threaded manner, and the other outlet is connected to an injecting element body (6) in a threaded manner. A cover plate (9) is fixedly mounted at a top end of the injecting element body (6). A mounting hole (22) used for connecting a threaded rod (14) is disposed on the cover plate (9). The other end of the threaded rod (14) is connected to a connector (12) in a threaded manner. A water taking signal nozzle (10) is disposed in a round through hole of the connector (12). A bolt (11) is used for fixing the disposal location of the water taking signal nozzle (10) to make the water taking signal nozzle (10) fixed above an outlet of the cover plate (22). The water taking signal nozzle (10) 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 (6); 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 (1) is primarily used for supplementing near water distribution of the double-nozzle injector capable of spraying evenly at a medium and low pressure, so as to improve spraying evenness.
