Abstract
A maintenance-free rotating compensator comprises an outer pipe (1) and an inner pipe (2) and is characterized in that a flange (5) is arranged in the middle of the inner pipe, a locating ring (4) and a sealing sleeve (3) are sequentially arranged on the right side of the flange in a sleeving mode, and the pipe portion of the sealing sleeve is in sealing contact with the outer circle of the inner pipe; the pipe portion of the sealing sleeve extends into the outer pipe, a gap is reserved between the pipe portion of the sealing sleeve and the inner wall of the outer pipe, a flange (7) is arranged at the left end of the outer pipe, and the left end of the sealing sleeve is located on the left side of the flange along a convex edge which extends in the radial direction; multiple bolts (8) penetrate through the locating ring, the convex edge of the sealing sleeve and the flange, a nut located at the left end of the bolt is screwed up so that the convex edge of the sealing sleeve presses the flange, and the sealing sleeve is made of a silicon rubber material. Due to the fact that the sealing sleeve is made of the silicon rubber material, after the inner wall of the sealing sleeve is abraded, the elasticity of silicon rubber still enables the pipe portion of the sealing sleeve to make contact with the inner pipe in a sealing mode, the sealing performance is maintained, maintenance workload is greatly reduced, and compared with an existing rotating compensator, the service life of the maintenance-free rotating compensator is prolonged.
Description
Technical field
The present invention relates to a kind of whirl compensator, this whirl compensator is for compensating expanding with heat and contract with cold of heat supply pipeline.
Background technique
The structure of existing whirl compensator comprises outer tube, interior pipe, one end of interior pipe is stretched in outer tube, the intersection of outer tube and interior pipe is provided with graphite grazing filler, relatively rotates, realize the compensation to heat supply pipeline when heat supply pipeline generation line expands between outer tube and interior pipe.Relatively rotating between outer tube and interior pipe can make stuffing box packing wear and tear, the sealability of whirl compensator is declined gradually, therefore with regard to needing, the stuffing box packing of whirl compensator being compressed after running a period of time, stuffing box packing radially being stretched and is close on outer tube and interior pipe.Owing to being that field maintenance cannot judge whether stuffing box packing is close on outer tube and interior pipe equably; usually can cause the phenomenon of monolateral compression; the wearing and tearing of aggravation stuffing box packing, increase the maintenance workload of whirl compensator sealability, shorten the working life of whirl compensator.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of maintenance-free rotary compensator, and this maintenance-free rotary compensator is when running, and seal element wearing and tearing are little, and when wearing and tearing occur seal element, energy auto-compensation wear extent, keeps the sealability of whirl compensator.
The structure of maintenance-free rotary compensator comprises outer tube 1, interior pipe 2, it is characterized in that, flange 5 is provided with at the middle part of interior pipe, the right side of flange is overlapped successively and is had positioning ring 4, stuffing box gland 3, the pipe portion of stuffing box gland seals with the cylindrical of interior pipe and contacts, the pipe portion of stuffing box gland stretches in outer tube, the pipe portion of stuffing box gland and the inwall of outer tube leave gap, the left end of outer tube is provided with flange 7, stuffing box gland left end is radially placed on the left of flange along the chimb stretched, multiple bolt 8 is through positioning ring, the chimb of stuffing box gland and flange, the nut of the left end of screwing bolts makes the chimb of stuffing box gland be pressed on flange, described stuffing box gland is made up of silicone rubber material.
On bolt, also cover has retaining to overlap 6, retaining cover is positioned at the root of bolt, the round edge of the large cylindrical section that retaining puts extend in the end face on the right side of flange 5, and the little cylindrical that retaining puts is in the outside of flange 5 circumference, and retaining puts the thickness of length slightly larger than flange 5 of little cylindrical section.
Be provided with recess 12 at the inwall of interior pipe one end, be provided with the hook portion 11 being folded to interior pipe upper notch in the end of stuffing box gland, described hook portion seals with the recess of interior pipe and contacts.
The edge of outer tube upper flange extends a body 10 vertically towards a left side, the inner circle of body matches with the cylindrical of positioning ring 4, and the inner circle of positioning ring matches with the cylindrical of interior pipe.
The feature of maintenance-free rotary compensator is, one, stuffing box gland is made up of silicone rubber material, and after the inner wall abrasion of stuffing box gland, the elasticity of silicone rubber still can make the pipe portion of stuffing box gland contact with the interior seal of tube, keeps sealability, greatly reduces maintenance workload; Two, the pipe portion of stuffing box gland and the inwall of outer tube leave gap, and the excircle part in Sealed casing pipe portion can not be worn and torn; Three, the frictional force between stuffing box gland and interior pipe is by the pressure initiation of fluid in the contractile force of stuffing box gland and whirl compensator, its frictional force is much smaller than the frictional force between graphite grazing filler in prior art and outer tube, interior pipe, frictional force in maintenance-free rotary compensator between stuffing box gland and interior pipe is little, the wearing and tearing of stuffing box gland can be reduced, can increase the service life compared with existing whirl compensator.
