Drip-type soil irrigation equipment - has cylindrical support fitting in pipe opening to regulate flow |
摘要 |
<p>The drip-type soil irrigation equipment comprises a fixed pipe with openings formed in it and supplying the liq. At each opening the flow is regulated by a cylindrical support (3) with a passage (4) formed in it and shaped so as to form a hermetic seal when inserted in the tube. A diaphragm (7) on the support seals the passage in proportion to the internal pressure in the tube. The diaphragm can be an elastic membrane opening in the axial direction to form a nozzle calibrated to suit the desired output.</p> |
