Abstract
A maintenance-free sleeve compensator is used for compensating expansion with heat and contraction with cold of a pipeline. It includes urceolus (9), inner tube (1) have been inserted in the urceolus, fill the gland packing between inner tube and the urceolus, the left end of gland packing pastes with the cover body of gland (2) mutually, the inner wall of urceolus has the tapering, the diameter of inner wall left end is greater than the diameter of inner wall right-hand member, the right-hand member of gland packing pastes with lateral wall (10) of urceolus mutually, gland flange (4) of gland are passed through bolt (7) with urceolus flange (5) of urceolus and are connected, leave the interval between gland flange (4) and the urceolus flange, the cover has spring (6) on the bolt, the spring is located urceolus flange left side, the spring. The inner wall of the outer cylinder is a cone, and radial pressure is applied to the sealing filler, so that effective sealing can be ensured; after the sealing packing is worn, the radial pressure can be continuously compensated under the action of the spring. The abrasion of the sealing filler is compensated, the maintenance workload is reduced, and the sealing performance of the sleeve compensator is maintained.
Description
Technical Field
The invention relates to a sleeve compensator which is used for compensating expansion with heat and contraction with cold of a pipeline.
Background
The sleeve compensator comprises an outer cylinder and an inner cylinder, wherein the inner cylinder is inserted into the outer cylinder, a sealing filler is arranged between the inner cylinder and the outer cylinder, and two ends of the sealing filler are pressed by a pressing cover to radially expand the sealing filler so as to realize sealing between the outer cylinder and the inner cylinder; in the operation process, when the pipeline takes place expend with heat and contract with cold, can relative movement between inner tube and the urceolus, make the seal packing wearing and tearing, along with the seal packing wearing and tearing clearance increase, in order to keep sealing performance, need frequently tighten the gland, it is big to maintain work load.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a maintenance-free sleeve compensator which can automatically compensate the abrasion of sealing filler, reduce the maintenance workload and maintain the sealing performance of the sleeve compensator.
The invention has the technical scheme that the maintenance-free sleeve compensator comprises an outer cylinder 9, wherein an inner cylinder 1 is inserted into the outer cylinder, sealing filler is filled between the inner cylinder and the outer cylinder, the left end of the sealing filler is attached to a sleeve body of a gland 2, and the maintenance-free sleeve compensator is characterized in that the sleeve body of the gland 2 is inserted between the inner cylinder and the outer cylinder, the inner wall of the outer cylinder has taper, the diameter of the left end of the inner wall is larger than that of the right end of the inner wall, the right end of the sealing filler is attached to a side wall 10 of the outer cylinder, a gland flange 4 of the gland 2 is connected with an outer cylinder flange 5 of the outer cylinder through a bolt 7, a gap is reserved between the gland flange 4 and the outer cylinder flange, a spring.
The maintenance-free sleeve compensator is characterized in that the inner wall of the outer cylinder is a cone, and has radial pressure on the sealing filler, so that effective sealing can be ensured; when the sealing packing is worn, the radial pressure can be continuously compensated under the action of the spring.
The maintenance-free sleeve compensator has the advantages that the abrasion of the sealing filler can be automatically compensated, the maintenance workload is reduced, and the sealing performance of the sleeve compensator is maintained.

Detailed Description
The utility model provides a non-maintaining sleeve compensator, it includes urceolus 9, the right-hand member welding of urceolus has takeover 11, the right part of inner tube 1 is inserted in the urceolus, fill gland packing 8 between inner tube and the urceolus, the gland packing is flexible graphite, the left end of gland packing pastes with the cover body of gland 2 mutually, the cover body of gland 2 is inserted between inner tube and urceolus, the inner wall of urceolus has the tapering, the diameter of inner wall left end is greater than the diameter of inner wall right-hand member, the right-hand member of gland packing pastes with the lateral wall 10 of urceolus mutually, gland flange 4 on the gland 2 and urceolus flange 5 on the urceolus are through a plurality of bolts 7 symmetric connection, leave the interval between gland flange 4 and the urceolus flange, the cover has.
The sealing packing can be clamped by screwing the nut, the inner wall of the outer cylinder is a cone, and the taper of the inner wall of the outer cylinder is preferably 1: 6, a certain radial pressure can be generated on the sealing filler by using a small clamping force, so that effective sealing can be ensured; when the sealing packing is worn, the radial pressure of the sealing packing can be continuously compensated under the action of the spring.
Claims (2)
