The utility model provides a water -cooling atmoseal device of optical fiber wire drawing stove, includes the base, has base water cooling chamber, base water cooling chamber baffle is established to the intracavity, has the base to advance that water pipe connector, base return water pipe connector, there is through hole of base in central authorities on the base, graphite felt keeps off the ring, and the supporting is on the base, and central authorities have graphite felt to hold the chamber, a set of graphite felt, the sealed mating holes of optical fiber perform that should organize graphite felt's central authorities corresponding and communicate with each other with through hole of base, atmoseal barrel, supporting have the water cooling of atmoseal barrel to separate the chamber on graphite felt keeps off the ring on the atmoseal barrel, the water -stop sheet is established to the intracavity, join in marriage corresponding to the lower part of one side of water -stop sheet to connect the cooling water to intake the upper portion of interface, opposite side to join in marriage and meet cooling water water return interface, the sealed lid of barrel, its central authorities establish the optical fiber perform jib hole of stepping down. Graphite part in the protection optical fiber wire drawing stove, avoid a set of graphite felt to be erodeed by the high temperature air current and reduce and optical fiber perform between sealed effect, it arouses the leakage to avoid the high temperature air current to erode, the promotion is to a set of graphite felt's protection effect.
