Schnellrohrkupplung mit einem Sicherheitsventil |
摘要 |
<p>A quick-coupling fitting for pipes comprises a female element (1) and a male element (2) that can be coupled together, formed by fixed parts (3, 4, 6, 9; 29, 32, 35) and axially sliding parts (10, 15; 37, 44). The fitting is provided with a valve (71; 80) apt for intercepting a communication port (79) between a conduit (65) and a passage port (78) for the fluid in the initial stages of the coupling action and for opening it in the final stages of the coupling action. A seal (40) of a fixed internal casing (32) is covered by a sliding bush (10) whatever is the axial position assumed by the bush (10) during the initial and final stages of the coupling action. <IMAGE></p> |
