Description
Technical field
The utility model relates to pipeline compensator, especially a kind of maintenance-free rotary compensator that is applicable to ultra-high pressure pipeline.
Background technique
When the industry heat distribution pipe network delivering vapors such as municipal heating systems, electric power, metallurgy, petrochemical industry, hot water or high-temperature water medium, because pipeline is affected by medium temperature to form to expand with heat and contract with cold, generally adopt telescopic compensator or whirl compensator to carry out compensate for displacement amount.Sleeve slip joint mainly consists of shell, slide cores pipe and stuffing box packing; due to telescopic joint; the displacement of its compensation pipeline stretches to compensate by slide cores pipe; compensation ability is subject to the restriction of structure; and the sealing between slide cores pipe and filler can not maintain a good state lastingly; after long-term use, easily produce and leak, make pipeline produce thermodynamic loss, affect economic benefit and environmental protection.
The current whirl compensator for heat distribution pipe network, its structure normally adopts bushing type, between inner and outer pipes, be provided with stuffing box packing chamber, stuffing box packing is put in Seal cage, by Gland press seal filler, realize sealing, but in High Temperature High Pressure Environmental Conditions, there are the following problems: the matching gap between rotary component is larger, be subject to pipeline thrust, the counterrotating poor stability of inner and outer pipes, easily produce the eccentric deflection of disalignment, thereby increased rotational resistance, reduced the flexibility of rotation compensation.For addressing the above problem, prior art is conventionally usingd steel ball or rolling bearing and as rolling friction pair, is controlled the coaxial rotation of inner and outer pipes, but after compensator uses one period, between inner and outer pipes, the sealability of stuffing box packing can significantly reduce, cause seal failure, occur leaking.
Model utility content
Deficiency for above existing pipeline compensator, the purpose of this utility model is to provide a kind of ultrahigh pressure heat distribution pipe network that is applicable to, and bit shift compensation amount is larger, adopt bolton filler and charging hole filling stuffing to combine, realize the whirl compensator of non-maintaining function.
The purpose of this utility model is achieved by the following technical solution:
Ultrahigh pressure maintenance-free rotary compensator, comprise rotation inner tube, outer sleeve, stuffing box packing and reducer pipe, described rotation inner tube is located in outer sleeve, outer sleeve is connected with reducer pipe, the outer surface of described rotation inner tube is provided with an annular boss, the internal surface of outer sleeve is provided with a bulge loop, between described rotation inner tube boss and outer sleeve bulge loop, is provided with a steel ball; One end of described outer sleeve is connected with reducer pipe, the other end is connected with filler flange by bolt, between described rotation inner tube boss and reducer pipe, be made as packing cavity, packing cavity is connected with the charging hole that is located at outer sleeve outer surface, in packing cavity, be provided with stuffing box packing II, between described outer sleeve bulge loop and filler flange, be provided with stuffing box packing I.
As optimal technical scheme of the present utility model, described rotation inner tube and annular boss are the overall structures being processed through metal cutting by forged steel.
As optimal technical scheme of the present utility model, described outer sleeve is the overall structure being processed through metal cutting by forged steel.
As optimal technical scheme of the present utility model, described reducer pipe is the overall structure being processed through metal cutting by forged steel, and described outer sleeve and reducer pipe are by being welded to connect and fixing.
As optimal technical scheme of the present utility model, the exterior edge face of described rotation inner tube and reducer pipe is respectively equipped with a chamfer surface, and the minimum range between this chamfer surface and inner-walls of duct is greater than 1.5 millimeters.
As optimal technical scheme of the present utility model, the angle between described chamfer surface and conduit axis equals 150 degree.
The beneficial effects of the utility model are: with respect to prior art, the utility model adopts bolton to compress filler and combines with charging hole filling stuffing, can make the good sealing state of the long-term maintenance of stuffing box packing, thereby realize the non-maintaining function of whirl compensator.Between the utility model rotation inner tube boss and outer sleeve bulge loop, be provided with steel ball, steel ball pivoting friction pair can be born larger moment of rotation, and rotates flexibly.The utility model is applicable to ultrahigh pressure heat distribution pipe network, and bit shift compensation amount is large, good seal performance, safe and reliable.
