摘要： The present application belongs to fluid control equipment, in particular, relates to directional controlling mechanism of fluidic sprinkler, comprising a rear reversing mechanism, a front reversing mechanism and a signal stream switching mechanism. A limiting shift rod of the rear mechanism rotate around a locating rod as the center after touching a limiting ring, then realize the reversing of the limiting shift rod. The reverse action of the limiting rod will finally lead a reversing arm to rotate by way of driving a reversing locating block, a rear reversing rod and a front reversing rod to rotate. The rear reversing mechanism, the front reversing mechanism and the signal stream switching mechanism act together, so as to switch a left-side signal stream nozzle and a right-side stream nozzle of a fluidic sprinkler, and bring about the reversing of the rotation direction of the fluidic sprinkler. Directional controlling mechanism of fluidic sprinkler is in a stepping state respectively in the clockwise and the counter clockwise working modes, so that the impact force on a rotary body is small, critical components tend to have a longer working life, an intermediate position does not exist during the reversing of the sprinkler, and the switching of the sprinkler is stable and reliable.

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 in a threaded manner, and the other outlet is connected to an injecting element body in a threaded manner. A cover plate is fixedly mounted at a top end of the injecting element body. A mounting hole used for connecting a threaded rod is disposed on the cover plate. The other end of the threaded rod is connected to a connector in a threaded manner. A water taking signal nozzle is disposed in a round through hole of the connector. A bolt is used for fixing the disposal location of the water taking signal nozzle to make the water taking signal nozzle fixed above an outlet of the cover plate. 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 evenly at a medium and low pressure, so as to improve spraying evenness.
