Flat pressure compensated emitter labyrinth runner built in

The pressure compensation labyrinth flow passage has a built-in flat emitter. Because the labyrinth flow passage faces back to the inner wall of drip irrigation belt, and the compensation piece is added, the flow rate can be avoided by the drip irrigation pipe wall going deep into the labyrinth flow passage, and the flow rate can be kept unchanged under the change of water pressure.
