Description
Technical field
The present invention relates to a kind of compensation of pipeline technology, especially a kind of whirl compensator, specifically a kind of pipeline is used
Packaging type whirl compensator.
Background technology
At present, whirl compensator has compensation rate big, easy for installation, total as a kind of thermal expansion of pipeline novel compensator
Body low cost and other advantages, it is widely applied in electric power, petrochemical industry and heating field.During typical rotary compensator structure is shown in
State patent ZL200610041301.4, by carrying out force analysis discovery to whirl compensator, existing structure design, which exists, not to be conformed to
Reason part, filler thrust variation tendency and pressure medium are on the contrary, so filler utilization rate is relatively low, particularly away from gland one
The filler of side can not play the effect of sealing at all.
The content of the invention
The purpose of the present invention be for existing whirl compensator edge face sealing member existing for thrust variation tendency with
Pressure medium change instead result in filler as seal utilization rate it is low the problem of, design one kind can make seal thrust
Variation tendency changes consistent pipeline packaging type whirl compensator with pressure medium.
The technical scheme is that：
A kind of pipeline packaging type whirl compensator, it includes reducer pipe 1, seal receptacle 2, gland 4 and core pipe 5, and core pipe 5 is set
The one end for having annular outer platform 7 is extend into reducer pipe 1, it is characterized in that reducer pipe 1, seal receptacle 2 and gland 4 are connected simultaneously two-by-two
Integral assembling is provided with annular seal space set 3, annular seal space set 3 in core pipe 5 in the cavity that seal receptacle 2, gland 4 and core pipe 5 are formed
One end is provided with annular inner convex platform 12, and the other end is connected by fastener 10 with gland 4；Annular outer platform 7, annular seal space set 3 and close
First of annular seal space is formed between envelope seat 2, in first described of annular seal space built with edge face sealing member 8, adjusts fastener 10
The size of first of annular seal space can be adjusted, so as to adjust the precompression of edge face sealing member 8；Annular seal space set 3, gland 4 and core
Second annular seal space is formed between pipe 5, in described second annular seal space built with ring face seal 9.
Described gland 4 is weldingly connected by connecting plate 6 and seal receptacle 2.
Ball 11 is mounted in the annular inner convex platform 12, gland 4 and the joint place of core pipe 5 of annular seal space set 3.
Described edge face sealing member 8 is high temperature resistant, the sealing material workpiece of high pressure.
Described fastener is bolt and butterfly spring component.
Beneficial effects of the present invention：
Traditional whirl compensator face seal structure is because gland and seal receptacle separate, thrust variation tendency and medium pressure
Power contrast（As shown in Figure 2）So that the filler away from gland side is not fully used, and sealing reliability is poor.
Gland and seal receptacle are connected by the present invention, and thrust variation tendency is consistent with pressure medium（As shown in Figure 3）, filler can be made
It is fully used, and as the rise of pressure medium, sealing reliability are also improved to some extent.
Present invention employs two sealed structures, first of end face seal structure has self sealss effect, with medium pressure
The rise of power, the thrust of edge face sealing member rise；The improved face seal structure of second equally has certain self sealss
Effect.It is more reasonable that the double-deck self sealing structure is set, and sealing effectiveness is more preferable, and sealing reliability is higher.
The volume of end face seal chamber for existing whirl compensator is non-adjustable, the volume energy of end face seal chamber of the invention
It is adjusted, it is achieved thereby that the adjustment of pretightning force.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the filler force diagram of traditional structure.
Fig. 3 is the filler force diagram of the present invention.
In figure：1- reducer pipes, 2- seal receptacles, 3- annular seal spaces set, 4- glands, 5- core pipes, 6- connecting plates, 7- annular outers
Platform, 8- edge face sealing members, 9- ring face seals, 10- fasteners, 11- balls, 12- annular inner convex platforms.
Embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1.
A kind of pipeline packaging type whirl compensator, it includes reducer pipe 1, seal receptacle 2, gland 4 and core pipe 5, and core pipe 5 is set
The one end for having annular outer platform 7 is extend into reducer pipe 1, and reducer pipe 1, seal receptacle 2 and gland 4 are connected two-by-two and integral assembling
In core pipe 5, wherein gland 4 is weldingly connected by connecting plate 6 and seal receptacle 2.Formed in seal receptacle 2, gland 4 and core pipe 5
Annular seal space set 3 is provided with cavity, annular seal space covers 3 one end and is provided with annular inner convex platform 12, and the other end passes through fastener 10 and gland 4
It is connected；First of annular seal space is formed between annular outer platform 7, annular seal space set 3 and seal receptacle 2, in first described of annular seal space
Built with edge face sealing member 8, adjustment fastener 10 can adjust the size of first of annular seal space, so as to adjust edge face sealing member
8 precompression；Second annular seal space is formed between annular seal space set 3, gland 4 and core pipe 5, it is built-in in described second annular seal space
There is ring face seal 9.The joint place of annular inner convex platform 12, gland 4 and core pipe 5 in annular seal space set 3 be mounted on ball 11 with
Rotated during guarantee whirl compensator work agile.In order to ensure sealing property, edge face sealing member 8 and ring face seal 9 all should be adopted
With the encapsulant of high temperature high voltage resistant, specially flexible graphite packing ring.In order to realize the long-term operation of product, fastener 10
Provided with disc spring, disc spring has pretension effect, is worn a little in filler, and bolt pretightening can automatically adjust in the case of declining, and keep away
Exempt from dielectric leakage in pipe.
During installation, first reducer pipe 1 and seal receptacle are weldingly connected；It is pressed core pipe 5, edge face sealing member 8, annular seal space successively again
