| 摘要 |
<p>The invention relates to a device for generating pressure forces on tubular components to be connected to one another, having a housing (3), a mechanically actuatable tensioning apparatus, a rubber-elastic deformable compound (5), which is arranged in the housing (3) and can be placed under pressure by the tensioning apparatus, and a mechanical indicator (8), which visually displays the tensioning state of the compound (5) to the outside, having a probe (10) in contact with the compound (5) and a sensor (11) implemented as a disk spring, for example, the indicator (8) having a separate display element (12), which is in contact with the probe (10) and/or the sensor (11). The sensor (11) is preferably under axial pre-tension in the installed state. The indicator is particularly used as a visual display for the tensioning state of a pipe coupling.</p> |
