Abstract
A press seal (1) with an elastomer body (2) includes a press body (9,10) which can be pressed against the elastomer body (2) by tightening a clamping bolt (4) and as a result, the elastomer body (2) is sealed on a line. The pressing body (9, 10) includes a display element (11) which can be visible in a display range (18) when a clamping state of the elastomer body (2) is reached. The pressing body (9, 10) includes a first (13) and a second press body part (14) movably mounted with respect to each other in an axial direction (3) parallel to the longitudinal axis (7) of the clamping bolt (4) such that when the elastomer body (2) is in the clamped state, it adopts a relative position modified with respect to the non-clamped initial state, which can be read on the display element (11).
Claims15
A press seal (1) for sealing against a line led through a through opening, having
- an elastomer body (2),
- a press body (9,10), and
- a tensioning bolt (4),
- wherein the press body (9,10) can be pressed against the elastomer body (2) by tensioning the tensioning bolt (4), so that the elastomer body (2) is tensioned and contacts the line sealingly,
- and wherein the press body (9,10) comprises a display element (11) which becomes visible in a display region (18) of the press body (9,10) when the elastomer body (2) reaches a tensioned state,
- wherein the press body (9,10) comprises a first (13) and a second press body part (14), the press body parts (13,14) being movable with respect to each other in an axial direction (3) parallel to the longitudinal axis (7) of the tensioning bolt (4), such that the press body parts (13,14) are in a different relative position when the elastomer body (2) is in the tensioned state, compared to a non-tensioned initial state, which can be read out via the display element (11),
- wherein the press body (9,10) is multi-part and comprises a pressing press body part (9) and a display press body part (10), wherein an area of the pressing press body part (9) is pressed against the elastomer body (2) by the tensioning bolt (4) during the tensioning, and the display press body part (10) comprises the first (13) and the second press body part (14) and the display element (11), wherein the display press body part (10) has a seat at the pressing press body part (9), secured against a rotation around the longitudinal axis (7) of the tensioning bolt (4).
