High pressure resistant metal graphite wound seal

Abstract

The utility model discloses a kind of high-pressure-resistant metal graphite winding type sealing elements, a high-pressure-resistant metal graphite winding type sealing element, including outer ring, the inner wall of outer ring is fixedly connected with inner ring, metal band is opened between outer ring and inner ring, the inner wall of metal band is attached with graphite band, high-pressure-resistant metal graphite winding type sealing element further includes replacement mechanism, replacement mechanism is set to the inside of outer ring.The utility model relates to autoclave technical field, the high-pressure-resistant metal graphite winding type sealing element, by the cooperation of clamping block, vertical groove and arc groove, damaged graphite band is replaced, solve the metal band and graphite band in the high-pressure-resistant metal graphite winding type sealing element interior mostly integral, after long time use, graphite band will gradually appear wear and tear damage condition, and because metal band and graphite band integral, even if only graphite band damage, often need to replace entire sealing element, to increase the replacement cost problem.
