Wherein: casing fitting seat 2 welds or is riveted on the casing 1; Fairlead sleeve 3 is fixed on the casing fitting seat 2 through 4 or 6 bolts 1; Floating ring 5 is installed between compromise joint 6 and the fairlead sleeve 3, and compromise joint 6 is adopted seal ring 12 sealings with joint 8; Flange pressing plate 9 and compromise joint 6 adopts 3 or 4 bolts 2 11 to be connected, compromise joint 6, and conduit 1 is integrally welded to be the interior pipeline assembly of casing; Compromise joint 6 is lower than casing main duct surface; Before the casing assembling, accomplish the assembling of this pipeline assembly, conduit 2 10, joint 8; Flange pressing plate 9 is integrally welded to be the outer pipeline assembly of casing, accomplishes this conduit line assembling in casing assembling back.
Described floating ring 5 is the split splicing construction of two semi-rings.
Described fairlead sleeve 3 internal surfaces that cooperate with floating ring 5 have the coating that adopts electrical spark alloyage graphitization.
Described pipeline flange type linkage structure of passing casing; Adopt the flange type linkage structure; Cancellation countertorque spanner structure, floating ring 5 is installed between compromise joint 6 and the fairlead sleeve 3, realizes the sealing of casing tapping and the installation and the thermal compensation of passing the casing pipeline.
The advantage of the utility model:
The described pipeline flange type linkage structure of passing casing of the utility model is passed the casing pipeline through design flange type linkage structure, and cancellation countertorque spanner structure is simplified linkage structure.Floating ring is installed in the compromise joint,, radially circumferentially can move freely with the casing fitting seat along casing with fairlead sleeve Spielpassung; Make the pipeline that passes casing have the compensation of installation and temperature compensation ability, reduced the Installation Stress of pipeline.The off position of pipeline is lower than casing duct internal surface in the casing, has improved the assembling of casing and pipeline.Fairlead sleeve graphitization coating not only reduces frictional force greatly, and has reduced the degree of wear of sleeve, has improved the sealing of casing position of opening.The pipeline that passes casing owing to there not be the finding of independent installation, has effectively avoided part to fall into the hidden danger in the motor duct through casing hole seat when assembling, has improved the maintenance of pipeline.
