Abstract
The utility model discloses a sealed rotary compensator belongs to a compensator. The utility model comprises an inner tube, an outer sleeve and a packing gland, wherein the inner surface of the outer sleeve is provided with an annular inner boss, and the outer surface of the inner tube is provided with an annular outer boss; be equipped with the sealing washer between filler and the gland, take the bite flower processing on the sealing washer and the contact surface of gland, inner tube to strengthened the utility model discloses a leakproofness.
Description
Technical Field
The utility model relates to a compensator, concretely relates to sealed rotary compensator.
Background
The rotary compensator is installed in the heat distribution pipeline to compensate the expansion and contraction of the heat distribution pipeline so as to protect the pipeline from damage. The structure of the rotary compensator generally comprises an outer sleeve and an inner tube, wherein one end of the inner tube extends into the outer sleeve, a sealing filler is arranged between the inner tube and the outer sleeve, and when the thermal pipeline generates thermal expansion and contraction, the inner tube and the outer sleeve rotate to absorb the axial displacement of the pipeline. The relative movement between the inner pipe and the outer sleeve can lead to the abrasion of the sealing filler, cause the loss of the sealing filler and reduce the sealing performance of the rotary compensator. In addition, the existing sealing element is mostly of a graphite structure, the strength of graphite is low, under the action of internal pressure thrust, the sealing cavity has great pressure on the sealing element, the graphite can be spread out towards two sides under the action of the pressure, and the sealing performance of the rotary compensator can be reduced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a rotary compensator that leakproofness is high.
The technical scheme of the utility model is that: a sealed rotary compensator comprises an inner tube, an outer sleeve and a packing gland, wherein the outer sleeve is sleeved on the inner tube, the packing gland is sleeved on the inner tube and is arranged at one end port of the outer sleeve, an annular inner boss is arranged on the inner surface of the outer sleeve, an annular outer boss is arranged on the outer surface of the inner tube, the packing gland and the annular outer boss are respectively positioned on two sides of the annular inner boss, a packing cavity is formed between the annular inner boss and the packing gland, sealing packing is arranged in the packing cavity, a plurality of balls are uniformly distributed in the cavity formed between the annular outer boss and the annular inner boss, a sealing ring is arranged between the sealing packing and the packing gland, one end of the sealing ring extends into the space between the inner tube and the outer sleeve, and the contact surface of the sealing ring.
According to a further technical scheme, the outer sleeve is provided with a filling nozzle communicated with the filling cavity.
According to the further technical scheme, an installation platform extends outwards from one end port of the outer sleeve close to the packing gland, and the packing gland is fixedly connected with a shell flange close to the other side of the installation platform through a stud bolt.
The utility model has the advantages that:
the utility model has the advantages that the sealing ring and the annular inner boss are arranged at the two ends of the sealing filler, and the plurality of balls are uniformly distributed in the cavity formed between the annular outer boss and the annular inner boss, so that the friction between the inner pipe and the outer sleeve pipe when the inner pipe rotates is reduced, and the abrasion of the sealing filler is reduced; the connection face between the sealing ring and the inner pipe and between the sealing ring and the outer sleeve is processed by adopting the knurl, the sealing performance of the sealing ring, the outer wall of the inner pipe and the inner wall of the outer sleeve is improved, the sealing filler in the filler cavity is limited to extend towards two sides, and the sealing performance of the device is effectively guaranteed.
Drawings
FIG. 1 is a schematic structural view of the present invention,
the device comprises an inner pipe 1, an inner pipe 11, an annular outer boss 2, a packing gland 3, a shell flange 4, sealing packing 5, a ball 6, an outer sleeve 61, an annular inner boss 7, a sealing ring 8, a stud bolt 9 and a filling nozzle.
Detailed Description
The invention will be further elucidated below by means of non-limiting examples, with the understanding that the invention is not limited thereto.
As shown in fig. 1, the utility model relates to a sealed rotary compensator, including inner tube 1, outer tube 6, gland 2, outer tube 6 suit is on inner tube 1, gland 2 suit is on inner tube 1, set up in the one end port department of outer tube 6, be equipped with annular inner boss 61 on the internal surface of outer tube 6, be equipped with annular outer boss 11 on the surface of inner tube 1, gland 2 and the outer boss 11 of annular are located the both sides of annular inner boss 61 respectively, form the packing cavity between annular inner boss 61 and the gland 2, be equipped with gland 4 in the packing cavity, evenly distributed has a plurality of ball 5 in the cavity that forms between annular outer boss 11 and the annular inner boss 61, when having reduced inner tube 1 rotatory and outer tube 6 between the coefficient of friction, thereby the wearing and tearing of gland 4 have been reduced. A sealing ring 7 is arranged between the sealing filler 4 and the filler gland 2, an injection filling nozzle 9 communicated with the filler cavity is arranged on the outer sleeve 6, and the sealing filler 4 in the filler cavity can be supplemented in time through the injection filling nozzle 9.
An installation platform extends outwards from one end port of the outer sleeve 6 close to the packing gland 2, and the packing gland 2 is fixedly connected with the shell flange 3 close to the other side of the installation platform through a stud 8. One end of the sealing ring 7 extends into the space between the inner tube 1 and the outer sleeve 6, and the contact surfaces of the sealing ring 7, the packing gland 2 and the inner tube 1 are all subjected to embossing treatment, so that the sealing performance of the sealing ring 7, the outer wall of the inner tube 1 and the inner wall of the outer sleeve 6 is improved, and the sealing packing 4 in the packing cavity is limited from extending towards two sides. Through adjusting stud 8, can adjust the length that sealing washer 7 stretched into between inner tube 1 and the outer tube 6, the effectual leakproofness of guaranteeing this device.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
