Zusammenfassung: | The invention relates to a rubber joint employed in irrigation pipeline couplings to ensure sealing at the working pressure and water discharge from the pipelines in case of reduced pressure as a consequence of suspended supply. According to the invention, the joint has a U-shaped cross section, comprising an external and internal lip (a and b), respectively, a front zone (c) and a sealing membrane (d) obturating some equally spaced rectangular cuttings (6) performed adjacently to the edge that separates the internal lip (b) from the sealing membrane (d).
Invenţia se referă la o garnitură din cauciuc, folosită la cuplajele conductelor de irigaţie, asigurând etanşarea la presiunea de lucru şi evacuarea apei din conducte atunci când presiunea scade, ca urmare a sistării alimentării. Garnitura conform invenţiei are o secţiune în formă de "U", alcătuită din nişte buze (a şi b) exterioară şi, respectiv, interioară, o zonă (c) frontală şi o membrană (d) de etanşare, care obturează nişte străpungeri (6) dreptunghiulare echidistante, practicate limitrof muchiei care desparte buza (b) interioară de membrana (d) de etanşare. |
