| 摘要 |
The invention relates to a device for pre-stressed sealed connection with flanges, that comprises a first flange (130) with a first contact surface (111), a second flange (140) with a second contact surface (121) opposite the first contact surface (111), a seal (160) provided in a seal housing (170) formed between the first and second contact surfaces, and clamping members (150) for the first and second flanges (130, 140). The first and second contact surfaces include a heel-forming local bearing area (Z1) provided in the vicinity of the seal (160). At least one (111) of the first and second contact areas includes, in the local bearing area (Z1) a parametered, e.g. conical, surface so that before tightening the clamping members (150), the contact between the first and second flanges (130, 140) at the local bearing area (Z1) is limited to a fraction of the surface of this local bearing area (Z1), while after tightening said clamping members (150; 250), the contact is evenly distributed on the entire local bearing area (Z1). |
