Sealing assembly and sealing equipment

The invention provides a sealing assembly and sealing equipment comprising the sealing assembly. The sealing assembly comprises a sliding sleeve, a sealing sleeve, a first limiting sleeve, a second limiting sleeve and an inner fixed sleeve. The first limiting sleeve and the second limiting sleeve are fixed to the two ends of the inner fixed sleeve correspondingly. The sliding sleeve is formed by splicing at least two sliding branched petals, and the two ends of each sliding branched petal are mounted in the first limiting sleeve and the second limiting sleeve in a radial moving fit mode correspondingly. The outer wall of the sealing sleeve is in seal fit with the inner wall surface of the sliding sleeve. The sealing sleeve is formed by splicing at least two sealing branched petals, and each splicing gap of the sliding branched petals corresponds to one sealing branched petal. An outer boss stretching outwards is arranged on the outer wall of the inner fixed sleeve. An inner boss stretching inwards is arranged
