High-pressure-resistant integrated leakage-free rotating compensator

Abstract

The invention relates to a high-pressure-resistant integrated leakage-free rotating compensator. The high-pressure-resistant integrated leakage-free rotating compensator comprises 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 penetrates through the outer sleeve to be inserted into the connecting pipe. 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 high-pressure-resistant integrated leakage-free rotating compensator thoroughly solves the problems that due to an existing welding method, weld joint flaw inspection can be hardly conducted and even can not be detected. Meanwhile, by arranging the abrasion-resistant carbon fiber layers and the anti-impact plate, loss of sealing material can be effectively reduced, and the sealing performance of the whole rotating compensator is improved.

Description

technical field [0001] The invention relates to a high-pressure resistant integrated non-leakage rotary compensator. Background technique [0002] Compensation devices are generally required to be installed and used in pipelines in industries such as electric power, petroleum, chemical industry, and heat power. Existing compensation devices usually include rotary compensators, bellows compensators, sleeve compensators, spherical compensators, etc., used to compensate pipeline shafts direction and radial displacement. When the pipeline transports high-temperature and high-pressure media, the requirements for the rotary compensator are higher: not only must there be sufficient displacement compensation, but also good sealing performance and long service life. [0003] The outer casing and connecting pipe of the existing rotary compensator are all welded into one body (see figure 1 ), such as Chinese patents 98227061.5, 02258709.8, 200620077450.1, 201120064777.6, 201110163209...

AI Technical Summary

Problems solved by technology

[0006] Therefore, it completely solves the potential safety hazard caused by welding the outer sleeve and the reducing tube in the rotary compensator; it solves the problem that the sealing packing between the outer sleeve and the inner tube of the rotary compensator is in the middle of the conveyed medium during the long-term use of the rotary compensator. The sealing effect decreases or fails due to the loss caused by the long-term impact, which affects the sealing performance of the entire rotary compensator; solves the sealing problem caused by the loss of the sealing packing due to the relative rotation between the outer sleeve and the inner tube The effect declines or fails, thereby affecting the sealing performance of the entire rotary compensator, which has become the goal pursued by those skilled in the art
