EMITTER AND DRIP IRRIGATION TUBE
Document Type and Number:
Japanese Patent JP2021029222
Kind Code:
A
Abstract:
To provide emitters that can adjust the flow rate appropriately even if the hardness of a diaphragm changes due to temperature changes.SOLUTION: The emitter has a pedestal 161 having a communication hole for communicating an irrigation fluid to a discharge port, a diaphragm 153 that has flexibility and is deformed toward the pedestal when it receives the pressure of the irrigation fluid in a tube, and a pedestal support unit 163 for supporting the pedestal, which has flexibility and is deformed so that the pedestal moves toward an inner wall surface 112 of the tube when the diaphragm presses the pedestal. The diaphragm and the pedestal support unit are more easily deformed at high temperatures than at low temperatures.SELECTED DRAWING: Figure 3
