The invention discloses a flow-adjustable detachable spiral type labyrinth emitter. The emitter is characterized by comprising an emitter body, a water outlet annular cavity in threaded connection with the outside of the emitter body, and capillary pipes in threaded connection with the two ends of the emitter body; a spiral labyrinth flow channel and an outer thread are arranged on the outer wall of the body emitter; a water inlet is formed in the outer wall close to one end of the emitter body, and the water inlet is communicated with an inner cavity of the emitter body and the spiral labyrinth flow channel; a water outlet is formed in the outer wall of the water outlet annular cavity, and the water outlet is communicated with the spiral labyrinth flow channel of the emitter body. The emitter body and the water outlet annular cavity can be conveniently screwed or separated, the flow at the water outlet is adjustable, cleaning and overhauling of the emitter body are facilitated, and the anti-blocking performance and reutilization performance of the whole emitter are improved.
