Description
Technical field
The utility model relates to a kind of gap sealing component and sealing strips.
Background technique
The equipment of many large sizes is all assembly made of having multiple component assemblings, it is generally the case that facilitate installation,
Can all there be certain installation gap between all parts, after installing under normal conditions, the gap between component is to compare
Small, it can even be closed completely, but in the case where some are special, the gap between component considers from design aspect
It has to retain, need the gap control between component in a certain range, such as the split blade type group in wind-powered electricity generation field
Close the vertical gap of tower.
But the gap between component be still need be sealed, with prevent rainwater, dust etc. enter component it
It is interior, influence equipment operation.Currently, lesser gap by gap filling with sealant be can reach the requirement of sealing because
Sealant, which has certain mobility and is hardened, needs the regular hour, when gap is wider or deeper, is filled out using sealant
It fills gap and is easy to appear defect, so under normal circumstances can be by rubber seal strip by the gap sealing between component, still
Certain alternate stress can be generated when the operation in some equipment later periods at gap, certain deflection occurs in component, and rubber is close
Seal strip may generate the phenomenon that fatigue fracture, and when in use between it is longer when phenomena such as generating aging, cause to seal
Failure, especially in outdoor environment, exposes to the sun and rain, the service life of rubber weather strip is shorter.
