Description

technical field [0001] The invention relates to a spray pipe, in particular to a switch rotary spray pipe. Background technique [0002] The nozzle refers to a device that accelerates the airflow by changing the geometry of the inner wall of the pipe section. The selection of nozzle material is closely related to nozzle structure and cooling method. Gas turbine engine nozzles are often made of nickel-based high-temperature alloys; the existing nozzles are inconvenient to install and inconvenient to open or close. Contents of the invention [0003] The present invention mainly solves the technical problems existing in the prior art, so as to provide a convenient butt joint with the spray hose through the spray pipe body, the spray can be realized through the spray tank, and the switch can be used by the plug to control the spray. The tube body is opened or closed, and the switch rotary injection tube is conveniently controlled by the swivel frame to rotate the plug. [0...
