The utility model discloses a pressure compensated drip irrigation device, which is structurally characterized in that a water inlet communicates with one end of a flow pass, a water outlet communicates with the other end of the flow pass, saw tooth projections are linearly distributed on two inner sides of the flow pass, elastic stoppers are distributed at equal intervals on the serrate projections, the width of the elastic stoppers is slightly smaller than the thickness of the saw teeth, the elastic stoppers are used for preventing the saw teeth from rubbing with the flow pass, and the elastic stoppers are inclined to the water flow direction; and a back fence is disposed at the back of the drip irrigation device and communicates with the water inlet. The elastic stoppers are added to the saw tooth projections of the traditional labyrinth flow pass to integrate compensation plates with the flow pass in design, so that errors of mounting the compensation plates and the flow pass are reduced, and local water head loss in mounting is reduced. The flow pass not only is capable of compensating pressure, but also can be used for production of inlaid drip irrigation belts, so that the problem of pressure compensation of the drip irrigation belts is not easy to achieve is solved. In addition, the pressure compensated drip irrigation device has the functions of self-cleaning and blockage proofing.
