Title:

HIGH-PRESSURE-RESISTANT INTEGRATED LEAKAGE-FREE ROTATING COMPENSATOR

Document Type and Number:

WIPO Patent Application WO/2015/184716

Kind Code:

A1

Abstract:

The present invention relates to a high-pressure-resistant integrated leakage-free rotating compensator, comprising an inner pipe, an outer sleeve, a connecting pipe and a filler flange. The outer sleeve is arranged on the inner pipe in a sleeved mode. One end of the inner pipe is inserted into the connecting pipe through the outer sleeve. The filler flange is arranged on the inner pipe in a sleeved mode. One end of the filler flange extends into the outer sleeve. An annular inner boss is arranged on the inner surface of the outer sleeve. The portion between the annular inner boss and the end, extending into the outer sleeve, of the filler flange is arranged on gland packing. The outer sleeve and the connecting pipe are of an integrally-formed integrated structure. An anti-impact plate is arranged between the gland packing and the annular inner boss. An abrasion-resistant carbon fiber layer is arranged between the gland packing and the outer surface of the inner pipe. An abrasion-resistant carbon fiber layer is arranged between the gland packing and the inner surface of the outer sleeve. The present invention thoroughly solves the problems that the weld joint flaw inspection is difficult to be performed and even can not be detected due to an existing welding method. Meanwhile, the loss of the sealing material can be effectively reduced by arranging the abrasion-resistant carbon fiber layers and the anti-impact plate, so that the sealing performance of the whole rotating compensator is improved.
