Seal arrangement for sealing a gap

A seal arrangement for a process device or plant, the seal arrangement comprising:

• a component arrangement with two components that sectionally adjoin one another in a region of a gap, wherein a groove is formed on one of the two components in a direction of the gap, the groove has an L-shape and is open toward an edge of the gap, wherein a first groove limb of the groove extends perpendicularly to a plane of the gap, and wherein a further groove limb of the groove is oriented perpendicularly to the first groove limb, which is formed so as to be open toward the space,
• wherein the first groove limb has a first groove-limb depth perpendicular to the gap, the further groove limb has a further groove-limb depth, and the first groove limb has a first groove limb width,
• wherein a seal is inserted into the groove, the seal having an L-shape corresponding to the L-shape of the groove, and the seal having has a first sealing limb and a second sealing limb perpendicular thereto, wherein the first sealing limb has a sealing foot,
• wherein the first sealing limb is configured such that it is inserted into the first groove limb, and the second sealing limb is configured such that it is insertable into the second groove limb and clamped tightly in the second groove limb,
• wherein, in a non-inserted state, portions of the second sealing limb have greater depth than the further groove-limb depth, the first sealing limb has a larger depth than the first groove-limb depth, and the sealing foot of the first sealing limb is wider than the first groove limb width seal has an oversize relative to dimensions of the groove and is inserted into the groove and tightly clamped therein,
• wherein, in each case, one channel, extending perpendicularly to a cross-section of the seal along a respective wall of the first sealing limb groove, is formed at least on three outer faces of the first sealing limb that face the walls of the groove in an inserted and compressed state of the seal in the groove, and the one or more channels are dimensioned such that, even in a state in which the sealing foot is inserted into the groove limb, a spacing still exists in a region of the channel in each case between the seal and the respectively associated wall of the groove,
• wherein at least two of these channels are formed in a region of the first longitudinal limb and extend approximately centrally in a region of the respective groove wall of this longitudinal limb, and
• wherein, above the sealing foot, a sealing region is formed having a peripheral face facing the edge of the gap, wherein the peripheral face is configured such that a substantially planar transition is formed between peripheral faces of the components, which extend at an angle to a plane of the gap, and the peripheral face.
