摘要 |
<p>The invention relates to a valve self-piercing tap for a plastic tube with a plastic housing (1) which has a branch connection member (2) and holds a valve body (3), in which a blocking body (5) engaged with a threaded spindle (6) and carrying a punch ring (9) for forming an opening in the plastic tube is displaceably arranged to be moved into axial engagement with a valve seat (10) to block access to the branch connection member (2). To avoid sealing rings, the valve body has at least one circumferential groove (12) with a side (13) directed towards the outlet (11). The housing is injection-molded around the valve body.</p> |
