Description
Technical field
Pipe expansion compensation technique field is the utility model is related to, more particularly, to a kind of pipeline whirl compensator.
Background technology
Pipeline is generally employed in pairs with whirl compensator, is absorbed or is compensated on one or more directions by angular displacement
Lateral displacement.
A kind of whirl compensator is disclosed in the utility model patent of Application No. 022587098, the compensator includes interior
Pipe, special-shaped pipe joint, inner tube extend to the postmedian of shape tube from shape tube splice port, are also equipped with special-shaped pipe joint spacing
Block, inner tube are equipped with sealing group and gland flange outside, encapsulant, seal receptacle and pressure are provided between seal receptacle, gland flange and inner tube
Lid flange is connected with hold-down bolt, with being equipped with a boss in the inner tube at the special-shaped pipe joint place of being combined, between boss and seal receptacle
Ball is provided with the groove of formation, the groove of the opposite inner tube of opening is additionally provided with gland flange, ball is also placed with groove.The benefit
Repay device and extend length of the inner tube in special-shaped pipe joint, inner tube is after shape tube splice port is extended in special-shaped pipe joint
Portion, thus fluid be not likely to produce vortex during exercise, pressure medium loss is small and prevent reverse dislocation, but the compensator
Defect is similarly present：1）The use of single seal, when conveying high-temperature high-pressure medium, between the sealed seat of liquid and inner tube
Gap enter seal chamber in, build-up of pressure reduces the durability of seal, exists and let out to the constant impingement of seal
Leakage problem；2）The rolling for being achieved with ball in groove of circulator angular displacement, but it is stuck to find that ball is present in use
Phenomenon, stability are poor.
The content of the invention
The purpose of this utility model is to overcome shortcoming present in prior art, there is provided a kind of pipeline rotation compensation
Device, the compensator instead of single sealing by composite seal, and replace ball by more reliable and more stable bulge loop, close to improve
Envelope effect simultaneously increases the stability and reliability of compensator, and the technical scheme of use is：A kind of pipeline whirl compensator, including
Core pipe, reducer pipe and seal receptacle, reducer pipe are integrally made or integrally welded with seal receptacle, and core pipe is sleeved in seal receptacle,
End cover is connected by connector with seal receptacle, it is characterised in that：Annular outer platform is set in the core pipe, matched is close
Annular inner convex platform is set on envelope seat；Annular groove, the annular groove, core pipe, end cover and seal receptacle are machined with annular inner convex platform
Between form compound seal chamber, compound seal intracavitary is equipped with Combined sealing element.
The technical characteristics of the utility model also has：The annular outer platform is towards setting bulge loop in the one side of annular inner convex platform.
The technical characteristics of the utility model also has：The Combined sealing element includes：Coordinate between annular groove and core pipe
Slip ring；Airtight and watertight padding between seal receptacle and core pipe.
The technical characteristics of the utility model also has：The slip ring is slip red copper ring.
The technical characteristics of the utility model also has：The end of the core pipe is extended into reducer pipe.
The beneficial effects of the utility model are：This whirl compensator is combined using packing seal and slip ring sealing
Mode, circumferential seal effect is not only realized, the axial seal effect also having had, avoid letting out for the lower fluid of pressure effect
Dew；Bulge loop stability is good, and durability is high, overcomes Caton phenomenon present in ball use；This whirl compensator has pressure-resistant
Property is good, compensation effect is good, service life is long, the advantage of good airproof performance.
Brief description of the drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment 1, and accompanying drawing 2 is the partial enlarged drawing of accompanying drawing 1, and accompanying drawing 3 is
The structural representation of embodiment 2,1 is core pipe, and 11 be bulge loop, and 2 be reducer pipe, and 3 be seal receptacle, and 4 be airtight and watertight padding, and 5 be sealed end
Lid, 6 be connector, and 7 be slip ring.
Embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is illustrated.The utility model discloses one kind
Pipeline whirl compensator, the compensator include core pipe 1, reducer pipe 2 and seal receptacle 3, bigger diameter end and the seal receptacle 3 of reducer pipe 2
It is integrally welded, calendering technology can be also used, reducer pipe 2 is integrally made from seal receptacle 3, core pipe 1 is sleeved in seal receptacle 3,
End cover 5 is connected by connector 6 with seal receptacle 3, and the annular inner convex platform of seal receptacle 3 is towards being machined with ring at end cover 5
Shape groove, forms compound seal chamber between annular groove, core pipe 1, end cover 5 and seal receptacle 3, compound seal intracavitary is equipped with combined type
Seal.
Core pipe 1 sets annular outer platform on the one end of reducer pipe 2, and annular outer platform is towards setting in the one side of annular inner convex platform
Bulge loop 11.
Combined sealing element in the present embodiment includes：Coordinate the slip ring 7 between annular groove and core pipe 1；Positioned at close
The airtight and watertight padding 4 sealed between seat 3 and core pipe 1, slip ring 7 can be to slide red copper ring.
Certainly, also the end of core pipe 1 can be extended into reducer pipe 2 as described in Example 2, such fluid is through core pipe 1
A pressure is formed to the annular outer platform of core pipe 1 after extension, under pressure effect, filler can play better seal effect
Fruit.
Certainly, described above is not limitation of the utility model, and the utility model is also not limited to the example above, this skill
The variations, modifications, additions or substitutions that the those of ordinary skill in art field is made in essential scope of the present utility model, also belong to
In the scope of protection of the utility model.
