Abstract

The invention provides an expansion ring sealed hot compensator for high-temperature gas conveying tubes, which comprises a pair of flanges, a pair of inner connecting tubes, a pair of inner annular plates, labyrinth seals, outer connecting tubes, ear plates, flame retardant coatings, a heat insulation filling material, and expansion ring sealed bellows, wherein the pair of flanges are arranged attwo ends; the pair of inner connecting tubes are respectively connected to the two flanges; the pair of inner annular plates forming expansion rings of the compensator are arranged at opposite ends o f the two inner connecting tubes; the labyrinth seals consisting of inner and outer sleeves are arranged on the inner ring sides of the two inner annular plates; the outer connecting tubes provided with compensating bellows are connected with the two inner connecting tubes through a pair of outer annular plates; the outsides of the two inner connecting tubes are provided with the ear plates provided with pull rods; the insides of the two inner connecting tubes are provided with the flame retardant coatings; the heat insulation filling material is arranged between the two inner annular plates and the inner and outer connecting tubes; and the opposite ends of the two inner connecting tubes are provided with the expansion ring sealed bellows. The expansion ring sealed hot compensator utilizesthe expansion ring sealed bellows to obstruct hot air round the labyrinth seals to prevent the hot air reaching the compensating bellows through the expansion rings and avoid the compensating bellows being damaged due to oxidization under the action of high temperature so as to effectively improve the operation life of the compensator.

Description

Expansion ring sealed hot compensator
Technical field
The present invention relates to the expansion compensation device that the high-temperature gas delivery line is used, be specifically related to a kind of expansion ring sealed hot compensator.
Background technique
Prior art is used for the high-temperature compensator of high-temperature gas delivery line, adopt inside and outside adapter composite structure, wherein the externally connected pipe assembling compensates bellows, the expansion ring of separated formation compensator in the inner connecting tube, the labyrinth seal that is comprised of fair water sleeves and outer sleeve is set between expansion ring, and the inboard at inner connecting tube arranges refractory layer, and heat insulation packing material is set between inside and outside adapter and expansion ring, and consists of the high-temperature compensator that multiple larger bit shift compensation amount can high temperature resistantly be arranged.The high-temperature compensator of said structure exists compensation ripple plumber and makes relatively short problem of life-span in the process that reality is used, its reason is that the labyrinth seal that is comprised of fair water sleeves and outer sleeve can not stop the high-temperature hot-air that is transferred to walk around the labyrinth fully and heat insulation packing material arrives the compensation bellows, and endlessly high-temperature hot-air arrival compensation bellows will make the temperature of compensation bellows rise rapidly, when compensation bellows temperature rises to more than 300 ℃, because the compensation bellows directly contacts with ambient air, corrugated stainless steel tubing can redden in very fast oxidation, after bellows is oxidized with regard to following the string failure damage in a short period of time.
Summary of the invention
The object of the invention is to for the problems referred to above, provide a kind of hot blast that can stop fully to arrive the compensation bellows, avoid compensating bellows and be subjected to the high temperature action oxidation, thereby Effective Raise compensation ripple plumber makes the expansion ring sealed hot compensator in life-span.
The technological scheme that realizes above-mentioned purpose is: a kind of expansion ring sealed hot compensator, it includes a pair of flange that places two ends, be connected to a pair of inner connecting tube is arranged on two flanges, the opposite end of two inner connecting tubes is provided with a pair of inner ring plate that consists of the compensator expansion ring, interior ring side at two inner ring plates is provided with by interior, the labyrinth seal that outer sleeve forms, link to each other with two inner connecting tubes through a pair of outer ring plate and to be connected to the externally connected pipe of assembling compensation bellows, arranged outside at two inner connecting tubes has at least two pairs of otic placodes, each is to being equipped with pull bar on the otic placode, inboard at two inner connecting tubes is provided with refractory layer, two inner ring plates and in, be provided with heat insulation packing material between externally connected pipe, be provided with the expansion ring seal bellows in the opposite end of two inner connecting tubes.
Technological scheme of the present invention also comprises: be provided with the second labyrinth seal that is comprised of inner and outer sleeves between two inner ring plates.
The present invention arranges the expansion ring seal bellows by the opposite end at two inner connecting tubes, formation is to the obstruct of the hot blast of walking around labyrinth seal, stop hot blast to arrive the compensation bellows of compensator by expansion ring, avoid compensating bellows and be subjected to the high temperature action oxidation damage, thus the operating life of Effective Raise compensator compensates bellows.
The present invention arranges the second labyrinth seal that is comprised of inner and outer sleeves between two inner ring plates, strengthen labyrinth seal to the iris action of hot blast, can further reduce the surface temperature of compensator, improves the resistance to high temperature of compensator.
