High-pressure tolerant integrated leakage-proof sleeve compensator

An integrated high-pressure resistant leak-free sleeve compensator, comprising

• an inner pipe, a connecting pipe, an outer sleeve sleeved on the inner pipe and a filler flange, and;
• one end of the filler flange extending into the outer sleeve;
• the outer sleeve having an inner surface provided with an annular inner boss;
• sealing filler being disposed between the annular inner boss and one end of the filler flange extending into the outer sleeve, configured to avoid gaps between inner and outer pipes and is capable of being refilled through the filler flange;
• the inner pipe having an outer surface provided with an annular outer boss to form an axial limit structure for the inner pipe;
• the filler flange and the outer sleeve being connected via a fastener;
• characterized in that, the connecting pipe and the outer sleeve are integrally molded to form an integrated structure;
• an anti-impact plate is disposed between the sealing filler and the annular inner boss, configured to reduce loss of the sealing materials and enhance the sealing performance of the integrated high-pressure resistant leak-free sleeve compensator;
• and
• wear-resistant carbon fiber layers are respectively disposed between the sealing filler and the outer surface of the inner pipe and between the sealing filler and the inner surface of the outer sleeve,
• wherein the integrated high-pressure resistant leak-free sleeve compensator is a rotary compensator which allows relative rotation between the outer sleeve and the inner pipe.
