Abstract
A high-sealability rotating compensator is used for compensating thermal expansion and cold contraction of pressure pipelines and comprises an outer pipe (1), an inner pipe (2) and a sealing cover (4), the left end of the inner pipe stretches into the outer pipe, and the right edge of the outer pipe extends out of a sealing flange (3) in the radial direction. The high-sealability rotating compensator is characterized in that the sealing cover is provided with a first sealing part (41), a torsion part (42) and a second sealing part (43), the inner pipe is sleeved with the first sealing part and the torsion part, a positioning plate (6) on the inner pipe is sleeved with the second sealing part which is clamped to one end face of the sealing flange through a clamping device, the first sealing part is fixedly sealed at the left end of the inner pipe through a tightening device (5), a gap is reserved between the torsion part of the sealing cover and the inner wall of the outer pipe, and the sealing cover is made of silicone rubber materials. Compared with the prior art, the high-sealability rotating compensator has the advantages that the torsion part of the sealing cover makes no contact with the inner wall of the outer pipe, when the outer pipe and the inner pipe rotate, the torsion part can slide on the inner pipe, friction force between the torsion part and the inner pipe is small, and the sealing cover is hardly abraded.
Description
Technical field
The present invention relates to a kind of high sealing whirl compensator, for expanding with heat and contract with cold of compensatory pressure pipeline.
Background technique
The pressure piping of transmitting fluid medium, by the impact of temperature of fluid medium and ambient temperature, can produce and expand with heat and contract with cold, in conventional whirl compensator cut-in pressure pipeline, the line utilizing the angular displacement of whirl compensator to carry out compensatory pressure pipeline expands or linear shrinkage, ensures the safe operation of pressure piping.The structure of existing whirl compensator comprises the outer tube and interior pipe that can relatively rotate, and one end of interior pipe is stretched in outer tube, flowing medium by outer tube and interior pipe, for preventing flowing medium from leaking from whirl compensator, filling graphite packing between outer tube and interior pipe.In use the relatively rotating of outer tube and interior pipe, can make graphite packing produce wearing and tearing, whirl compensator sealability is declined gradually, so that lose efficacy.The blind power of pulling can be applied to whirl compensator when pipeline expands with heat and contract with cold in addition, outer tube and interior pipe be rubbed secundly to graphite packing, exacerbates the wearing and tearing of graphite packing.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of high sealing whirl compensator, and it can reduce the wearing and tearing of Sealing greatly, keeps the sealability of whirl compensator.
High sealing whirl compensator comprises outer tube 1, interior pipe 2, stuffing box gland 4, the left end of interior pipe is stretched in outer tube, the right hand edge radial direction of outer tube extends sealing flange 3, it is characterized in that, stuffing box gland has the first sealed department 41, torsional part 42 and the second sealed department 43, first sealed department and torsional part cover are on inner pipe, second sealed department quilt cover positioning disk 6 on inner pipe passes through a gripping means grips on the end face of sealing flange, described clamp device is by overpaying bolt 9 and nut 10 is formed, bolt is through sealing flange, second sealed department and positioning disk, first sealed department of stuffing box gland is fixed on the left end of interior pipe by fastening device 5 sealing, the torsional part of stuffing box gland and the inwall of outer tube leave gap, described stuffing box gland is made up of silicone rubber material.
For improving the endurance of stuffing box gland, the cross section of described torsional part 42 is plum blossom-shaped.
Compared with prior art, the torsional part of the stuffing box gland of high sealing whirl compensator and the inwall of outer tube contactless, when outer tube and interior pipe rotate (rotation angle for-25 spend to 25 degree), torsional part can slide on inner pipe, and between it, the very little stuffing box gland of frictional force is almost without wearing and tearing; The wearing and tearing that the blind power of pulling also can not be aggravated stuffing box gland are produced when pipeline expands with heat and contract with cold.Because stuffing box gland is without the sealability that can keep high sealing whirl compensator of wearing and tearing, the sealing life of stuffing box gland depends on its natural aging life-span, the impact of the stuffing box gland that silicone rubber is made in high sealing whirl compensator not by air and light is not easily aging, and its natural aging life-span can reach many decades.

Embodiment
Existing accompanying drawings the specific embodiment of the present invention.
High sealing whirl compensator comprises outer tube 1, interior pipe 2, stuffing box gland 4, the left end of interior pipe is stretched in outer tube, the right hand edge radial direction of outer tube extends sealing flange 3, it is characterized in that, stuffing box gland has the first sealed department 41, torsional part 42 and the second sealed department 43, first sealed department and torsional part cover are on inner pipe, second sealed department quilt cover positioning disk 6 on inner pipe passes through a gripping means grips on the end face of sealing flange, first sealed department of stuffing box gland is fixed on the left end of interior pipe by fastening device 5 sealing, the torsional part of stuffing box gland and the inwall of outer tube leave gap, described stuffing box gland is made up of silicone rubber material, the Environmental Conditions temperature of silicone rubber is-20 DEG C to 330 DEG C.
Described clamp device is by overpaying bolt 9 and nut 10 is formed, and bolt is through sealing flange, the second sealed department and positioning disk.
Described fastening device is the Stainless Steel Wire ring that can wring, and also can be the clip of opening band screw, nut.
When relatively rotating between outer tube and interior pipe (rotation angle to spend to 25 degree-25 between), the torsional part of stuffing box gland reverses thereupon, and the cross section of torsional part can be ring-type; Also can be: the wall of torsional part has many places projection vertically, the cross section of torsional part is plum blossom-shaped, to improve the elasticity of torsional part, improves the endurance of stuffing box gland.
For the blind power of pulling reducing pipeline causes the friction of the hole of positioning disk and interior pipe cylindrical, between the hole of positioning disk and interior pipe cylindrical, leave the radial clearance of 2 millimeters of scopes.
When pipeline is installed high sealing whirl compensator, axial float may be produced between outer tube and interior pipe stuffing box gland is stretched or compresses, cause and inconvenience is installed, for the generation of anti-phenomenon here, bolt overlaps limited location cover 7, stop collar is positioned at the right of positioning disk, be fixed with the baffle plate 8 of plate-like on inner pipe, baffle plate is positioned at the right of positioning disk, stop collar is in the outside of baffle plate circumference, the length of stop collar is slightly larger than the thickness of baffle plate, the flange of ring-type is had at the right-hand member of stop collar, this flange reaches in the circumference of baffle plate, stop collar can prevent the axial float between outer tube and interior pipe after fixing.
For convenience of the assembling of high sealing whirl compensator self and the installation on pipeline, be respectively equipped with adpting flange 11 at the left end of outer tube and interior pipe right-hand member.
