Title
(EN) EMITTER AND DRIP IRRIGATION TUBE
Abstract
(EN)
An emitter according to the present invention includes a water intake part a discharge part a first flow path a second flow path a flow rate decreasing part a flow path opening/closing part a pressure reducing flow path and a bypass flow path. The pressure reducing flow path is provided to the first flow path on the upstream side of the flow rate decreasing part reduces the pressure of an irrigation liquid and guides the irrigation liquid to the flow rate decreasing part. The bypass flow path is provided to the second flow path on the upstream side of the flow path opening/closing part and guides the irrigation liquid to the flow path opening/closing part in a state where the pressure of the irrigation liquid is maintained at a pressure higher than that of the irrigation liquid that has passed through the pressure reducing flow path. When the pressure of the irrigation liquid is lower than a first pressure the irrigation liquid passes through the pressure reducing flow path and the bypass flow path to be guided to the discharge part. When the pressure of the irrigation liquid is a second pressure or higher the second flow path is closed by the flow path opening/closing part and the irrigation liquid passes through the pressure reducing flow path to be guided to the discharge part.
