Abstract
The utility model relates to a rotary compensator, for compensating the thermal expansion and cold shrinkage of linear section in a thermal pipe, which comprises an inner pipe, a seal gland and a seal base which are sheathed outside the inner pipe, wherein the seal stuff is stuffed between an enclosed space formed by the seal gland, the seal base and the outer wall of the inner tube. The rotary compensation is characterized in that the flange of the seal base is abut with the end tube flange, which are provided with a seal gasket therebetween, a screw rod is penetrated through the flange of the seal base, the end tube flange and the flange of the seal gland, one end of the screw rod is fixed by a nut and the another end via a nut is pressed on the flange of the seal gland via a spring sheathed on the screw rod. The utility model adopts the preloading force of the spring to press the seal stuff, to automatically compensate the abrasion of the seal stuff, to keep good seal effect for long time. The apertures of the inlet and the outlet pipes are same for reducing flow speed loss.
Description
Technical field
The utility model relates to a kind of bit shift compensation device of pipeline, especially relates to the whirl compensator that uses on a kind of heat distribution pipeline.
Background technique
Heat distribution pipeline produces corresponding physical deformation because of the fed sheet of a media variation of temperature, and the distortion of heat distribution pipeline will cause great harm to the pipe safety operation if can not obtain timely, compensation fully.Present heat distribution pipeline generally device has the compensation of pipeline device, using more is a kind of whirl compensator of realizing compensation that relatively rotates by inner and outer pipe, compensate the displacement of expanding with heat and contract with cold of piping cathetus pipeline section in the swing offset mode, whirl compensator can not use separately, forms the supporting uses of special pipeline section such as π type or Ω type usually together with two or three.China Patent No. 02258709.8 discloses a kind of whirl compensator, because of approval simple in structure, that rotation is flexible, compensation rate obtains market greatly.The sealing configuration that this compensator adopts is that stuffing box packing is inserted in the seal space that is made of sealing gland, sealing seat and outer wall of inner tube, comes the fit sealing gland by bolt, nut, thereby makes stuffing box packing play the effect of sealing in seal space.This sealing configuration is after long-term the use, because the wearing and tearing of stuffing box packing make sealing gland loosening, thereby causes poorly sealed even leakage.In addition, the pipe fitting that is connected with sealing seat in this compensator adopts reducer pipe fitting, when MEDIA FLOW easily produces resistance through herein the time, causes the loss of flow velocity.
The model utility content
The applicant has carried out research and has improved at above-mentioned shortcoming, and a kind of wearing and tearing of energy automatic compensation sealing filler and the whirl compensator that can reduce the flow velocity loss are provided.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of whirl compensator, comprise interior pipe, sealing gland and sealing seat are enclosed within respectively outside the interior pipe, stuffing box packing is filled out in the seal space that is made of sealing gland, sealing seat and outer wall of inner tube, the sealing seat flange dock with the end pipe flange, between device sealing gasket is arranged, screw rod passes the sealing seat flange, holds pipe flange and sealing gland flange, one end of described screw rod is fastening by nut, and the other end is pressed on the sealing gland flange by the spring that is enclosed within on the screw rod by nut.
Device has ball in the annular closed space that the annular boss of the internal surface of sleeve pipe of the annular boss of Guan Yiduan outer wall and sealing seat constitutes in above-mentioned; Have annular groove on the inwall of the sleeve pipe of above-mentioned sealing gland, device has ball in the described annular groove; The internal diameter of pipe is identical with the internal diameter of the pipeline of end pipe in above-mentioned.
Technique effect of the present utility model is:
1. owing to adopt initial tension of spring to compress the structure of stuffing box packing, the wearing and tearing of stuffing box packing are compensated automatically, can keep the better seal effect for a long time.
2. thereby import and export the loss of the identical minimizing of pipe fitting bore flow velocity.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 1, pipe 1 in the utility model comprises is managed outside 1 in sealing gland 4 and sealing seat 6 are enclosed within respectively.Sealing gland 4 is made of flange 401 and sleeve pipe 402, and it can time processing be shaped or be welded by both; Sealing seat 6 is made of flange 601 and sleeve pipe 602, and it can time processing be shaped or be welded by both.Stuffing box packing 5 is filled out in the seal space that pipe 1 outer wall constitutes in being reached by sleeve pipe 402 sides, sleeve pipe 602 inwalls.Flange 601 with the end pipe flange 801 dock, between device sealing gasket 9 is arranged, sealing gasket 9 is high temperature resistant and high voltage bearing no asbestos seal pad or metal wound gasket.End pipe flange 801 constitutes end pipe 8 with end pipeline 802, and end pipe 8 can time processing be shaped or be welded by both.Screw rod 10 passes the unthreaded hole on sealing seat flange 601, end pipe flange 801 and the sealing gland flange 401, one end of screw rod 10 is fastening by nut 12, the other end is pressed on the sealing gland flange 401 by the spring 3 that is enclosed within on the screw rod by nut 11, and the pretightening force of spring 3 is pressed on stuffing box packing 5 in the seal space by sealing gland 4.After long-term the use, stuffing box packing 5 is is progressively worn and torn, and the pretightening force of spring 3 is pressed in the seal space stuffing box packing 5 all the time, and the wearing and tearing of automatic compensation sealing filler keep sealing effect good, and in the present embodiment, what stuffing box packing 5 was used is graphite material.As can see from Figure 1, sealing gland 4, sealing seat 6 and end pipe 8 constitute relatively-stationary integral body by screw rod 10, spring 3 and nut 11,12, and fixing of circumferencial direction do not arranged between this integral body and the interior pipe 1, and therefore, both can relatively rotate.
As shown in Figure 1, on the pipe 1 one end outer walls annular boss is arranged in above-mentioned, with the annular boss looping closed space of sealing seat sleeve pipe 602 inwalls, device has ball 7 in the annular closed space.Sealing gland sleeve pipe 402 inwalls are provided with annular groove, and device has ball 2 in the annular groove.Installed after ball 7 and 2, relatively rotating in making between pipe 1 and sealing gland 4 and the sealing seat 6 is more level and smooth.In addition, in the present embodiment, the internal diameter of interior pipe 1 is identical with the internal diameter of end pipeline 802, can reduce the resistance that MEDIA FLOW produces when compensator, reduces the loss of flow velocity.
The pretightening force of spring 3 is adjusted before product export as requested, during installation, the two ends of whirl compensator respectively with pipeline in pipe fitting weld.A arrow among Fig. 1 is represented the flow direction of medium in whirl compensator.
