Abstract
A thrust-free rotary compensator is characterized in that a group of graphite packing rings which are axially arranged, closely attached and V-shaped in cross section are filled between a rotating core tube and a shell, a compression flange and a compression disc are respectively arranged at two ends of each graphite packing ring, a conical centering sleeve and an adjustable compression ring are arranged between the port of the compression flange and the rotating core tube, an anti-friction ring is arranged on one side of the compression disc, and a secondary sealing element clamped between the compression flange and the rotating core tube is arranged at one end of the centering sleeve. The utility model discloses installing in the pipeline of heating power pipe network in groups, through the axial displacement of the rotation compensation pipeline between core pipe and shell, the rotational freedom, the axiality obtains guaranteeing, and the compensation ability is big, and sealing performance is good, and the adjustment is maintained conveniently, can keep the result of use in long-term operation.
Description
Technical field
The utility model relates to a kind of ducted Zero-thrust rotary compensator of heat distribution pipe network that is used for.
Background technique
When industry heat distribution pipe network delivering vapors such as municipal heating systems, electric power, metallurgy, petrochemical industry, hot water or high-temperature water medium, form and expand with heat and contract with cold, generally adopt the slip-type expansion joint compensate for displacement because pipeline is influenced by medium temperature.Sleeve expansion joint mainly is made of shell, slide cores pipe and stuffing box packing, because slip-type expansion joint stretches compensate for displacement by the slide cores pipe, compensation ability is subjected to the restriction of structure, and the sealing between slide cores pipe and the filler can not be lastingly and produce and leak, and makes pipeline produce thermodynamic loss.At present, the someone proposes to replace slip-type expansion joint with rotary compensator, and adopt one group of axial arranging and be adjacent to, the graphite packing circle of cross section forming V-shape is as stuffing box packing, its compensation ability and sealability improve a lot.But still adopt the steel ball location between this compensator China and foreign countries shell-and-core pipe, after using a period of time, because wearing and tearing produce the gap, and the gap is progressively strengthened and can't be adjusted, make outer shell-and-core pipe disalignment, produce angular displacement, and the stuffing box packing unbalance stress, leak easily, and then influence the using effect of compensator.
The model utility content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art part, and it is big to propose a kind of compensation ability, and good seal performance is easy to adjust, can keep the Zero-thrust rotary compensator of using effect in long-time running.
The technical solution of the utility model is: Zero-thrust rotary compensator, the supported flange and the compression plate that comprise rotating core pipe, shell, stuffing box packing and two ends thereof, described stuffing box packing be one group of axial arranging and be adjacent to, the graphite packing circle of cross section forming V-shape, improvements are to be provided with bevel-type centring sleeve and adjustable retainer ring between described supported flange port and the rotating core pipe, are provided with wearing ring between the port of described rotating core pipe and the above-mentioned compression plate.
Described bevel-type centring sleeve is provided with shaft orientation opening groove, and the male cone (strobilus masculinus) of centring sleeve and the inner conical surface of described retainer ring match; Described retainer ring is connected with the screw of supported flange by band spring washer and locking nut; The side of described wearing ring is arc shaped surface or is provided with annular recess; Be provided with self lubricating material in the described groove; One end of described centring sleeve is provided with the secondary seal spare that is clipped between supported flange and the rotating core pipe.
The utility model is connected in the pipeline of heat distribution pipe network with compensator isometrical more than three or three when using usually in groups, adopts welding or flange ways of connecting, and core tube and tube road internal diameter equates that media flow is unimpeded, does not produce thrust.During work, compensate the displacement of pipeline because of expanding with heat and contract with cold and producing by relatively rotating between core pipe and shell, the core pipe rotates free, and compensation ability is big.Used stuffing box packing produces lateral expansion under the pretightening force effect, be provided with secondary seal spare, good sealing effect in addition.Particularly the utility model adopts the steel ball in the existing compensator of bevel-type centring sleeve replacement, by the adjustment of retainer ring, the radial clearance in the rotation of core pipe is remained in the reasonable range, thereby make this compensator keep good using effect in long-time running.In addition, between the compression plate of core tube opening place and stuffing box packing, be provided with wearing ring, the surface friction drag in the time of reducing the rotation of core pipe, and play auxiliary centering effect, help strengthening the compensator using effect.

Accompanying drawing is the utility model structural representation.
Embodiment
As figure, fill stuffing box packing 8 between rotating core pipe 1 and the shell 7, the sealing filler is 12 axially arranges and is adjacent to, and section becomes the graphite packing circle of V-type, and the graphite cement bulking agent is arranged therebetween.One end of stuffing box packing is provided with supported flange 6, and it is connected with shell by bolt, and the other end is provided with compression plate 9, and a side of compression plate is provided with wearing ring 10, and a side of wearing ring is an arc shaped surface, and the groove of opposite side is embedded in the nylon6 chips 11 of selflubricating.Be provided with bevel-type centring sleeve 2 and adjustable retainer ring 4 between supported flange port and the rotating core pipe, centring sleeve is provided with shaft orientation opening groove, the male cone (strobilus masculinus) of centring sleeve and the inner conical surface of retainer ring match, and retainer ring is connected with supported flange by the screw 3 that has spring washer and locking nut.One end of centring sleeve is provided with the secondary seal spare 5 that is clipped between supported flange and the rotating core pipe, adopts the oiliness teflon.
Claims (6)
