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 packaging type whirl compensator.
Background technology
At present, whirl compensator has compensation rate low cost and other advantages big, easy for installation, overall as a kind of thermal expansion of pipeline novel compensator, is widely applied at electric power, petrochemical industry and heating field.Typical rotary compensator structure is shown in Chinese patent ZL200610041301.4, by whirl compensator is carried out force analysis discovery, there is unreasonable part in existing structure design, filler thrust variation tendency and pressure medium are contrary, so filler utilization rate is relatively low, particularly cannot play the effect of sealing at the filler away from gland side at all.
Summary of the invention
Thrust variation tendency and the pressure medium change that it is an object of the invention to exist for the edge face sealing member of existing whirl compensator instead results in the problem that the utilization rate of the filler as seal is low, designs and a kind of seal thrust variation tendency can be made to change 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, core pipe 5 is provided with one end of annular outer platform 7 and extend in reducer pipe 1, it is characterized in that reducer pipe 1, seal receptacle 2 and gland 4 are connected two-by-two and integral assembling is on core pipe 5, annular seal space set 3 it is provided with in the cavity that seal receptacle 2, gland 4 and core pipe 5 are formed, annular seal space overlaps 3 one end and is provided with annular inner convex platform 12, and the other end is connected with gland 4 by securing member 10；Form first annular seal space between annular outer platform 7, annular seal space set 3 and seal receptacle 2, at described first annular seal space built with edge face sealing member 8, adjust securing member 10 and can adjust the size of described first annular seal space, thus adjust the precompression of edge face sealing member 8；Annular seal space overlaps 3, forms second annular seal space between gland 4 and core pipe 5, at 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.
Annular inner convex platform 12, gland 2 at annular seal space set 3 are mounted on ball 11 with the joint place of core pipe 5.
Described edge face sealing member 8 is high temperature resistant, the sealing material workpiece of high pressure.
Described securing member is bolt and butterfly spring assembly.
Beneficial effects of the present invention:
Tradition whirl compensator face seal structure separates with seal receptacle due to gland, thrust variation tendency and pressure medium 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, thrust variation tendency consistent with pressure medium (as shown in Figure 3), filler can be made to be fully used, and along with the rising of pressure medium, sealing reliability is also improved to some extent.
Present invention employs two seals structure, first end face seal structure has self sealss effect, and along with the rising of pressure medium, the thrust of edge face sealing member rises；The face seal structure that second improves has certain self sealing action equally.This bilayer self sealing structure arranges more reasonable, and sealing effectiveness is more preferable, and sealing reliability is higher.
Volume for the end face seal chamber of existing whirl compensator is non-adjustable, and the volume energy in the end face seal chamber of the present invention is adjusted, it is achieved thereby that the adjustment of pretightning force.

In figure: 1-reducer pipe, 2-seal receptacle, 3-annular seal space set, 4-gland, 5-core pipe, 6-connecting plate, 7-annular outer platform, 8-edge face sealing member, 9-ring face seal, 10-securing member, 11-ball, 12-annular inner convex platform.
Detailed description of the invention
The present invention is further illustrated with embodiment below in conjunction with the accompanying drawings.
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, core pipe 5 is provided with one end of annular outer platform 7 and extend in reducer pipe 1, reducer pipe 1, seal receptacle 2 and gland 4 are connected two-by-two and integral assembling is on core pipe 5, and wherein gland 4 is weldingly connected by connecting plate 6 and seal receptacle 2.Being provided with annular seal space set 3 in the cavity that seal receptacle 2, gland 4 and core pipe 5 are formed, annular seal space overlaps 3 one end and is provided with annular inner convex platform 12, and the other end is connected with gland 4 by securing member 10；Form first annular seal space between annular outer platform 7, annular seal space set 3 and seal receptacle 2, at described first annular seal space built with edge face sealing member 8, adjust securing member 10 and can adjust the size of described first annular seal space, thus adjust the precompression of edge face sealing member 8；Annular seal space overlaps 3, forms second annular seal space between gland 4 and core pipe 5, at described second annular seal space built with ring face seal 9.Annular inner convex platform 12, gland 2 at annular seal space set 3 rotate agile when being mounted on ball 11 to ensure whirl compensator work with the joint place of core pipe 5.In order to ensure sealing property, edge face sealing member 8 and ring face seal 9 all should use the encapsulant of high temperature high voltage resistant, specially flexible graphite packing ring.In order to realize the long-term operation of product, securing member 10 is provided with disc spring, and disc spring has pretension effect, weares and teares a little at filler, and bolt pretightening can be automatically adjusted in the case of declining, it is to avoid dielectric leakage in pipe.
During installation, first reducer pipe 1 and seal receptacle are weldingly connected；Press-fit core pipe 5, edge face sealing member 8, annular seal space set 3 and ring face seal 9 and gland 4 the most successively, and seal receptacle 2 and gland 4 are welded to connect by connecting plate 6；Last tightening fastener parts 10, completes overall structure.
In order to realize cooperating of two seals, the precompressed shrinkage of edge face sealing member 8 can appropriateness increase when mounted, and during to ensure to tight a bolt, annular seal space is filled in end face seal filler resilience.
Part that the present invention does not relate to is the most same as the prior art maybe can use prior art to be realized.
