The elongated end of swivel pin 605 and connecting plate 612 constitutes a high position and linked, and is easy to inspection hole cover 601 and window flange 602 to realize soon
Speed is separated and closed, and will not produce interference problem.
Annulus inner chamber 202 in compensator 2 is in cone cavernous structure, and so, adjustment angle is adjusted by original 1.5 ° to existing
3 °, it is individual layer pouring material structure to cover in compensator 2 in the fire resisting pouring material 212 in upper internal lining pipe 211；Individual layer pouring material
Have：Low thermal conductivity, heat endurance are good, refractoriness is high, good heat preservation performance, operating procedure are simple, it is with short production cycle the advantages of.Fire resisting
The structure of pouring material 212 is in taper hole shape structure in cylindrical form, endoporus for outside, by changing the large and small end diameter of conical bore
Difference, changes the travelling gap at the travelling end of compensator, realizes the wide-angle bit shift compensation of air-supply arrangement.Annulus inner chamber 202 is using light
Matter heat-barrier material, strengthens heat insulation and preservation effect.
The joint face of compensator 2 and middle section 3 and/or lower section 4 is into cambered surface（Or referred to as sphere）Attachment structure, cambered surface is good
Spacing property facilitate the relative displacement on two contact surfaces, ensure compensator 2 and middle section 3 and/or lower save 4 and overlap or formed in axis
During angle, connection surface all has good cooperation, prevents leakage.
The curved structure in the bottom of fire resisting pouring material 212 in upper internal lining pipe 211 in compensator 2,212 layers of fire resisting pouring material
The action of arcuate structure shortens 20mm, and angle of climbing reduces 10 °, reduces regulation resistance, convenient regulation（The shortcoming of original structure is
Frictional resistance is big, and regulation is difficult）.
