Abstract
The utility model discloses a. high-pressure balanced compensator The high-pressure balanced compensator comprises flanges at two ends, three bellows compensators which are coaxially and serially connected and have the same structure, annular plates radially and fixedly connected to the outer walls of connecting pipes at the two ends, and pull rods. The main bellows compensator positioned in the middle has a larger aperture than the auxiliary bellows compensators positioned on the two sides; 6-24 axial through holes are uniformly distributed in the annular plates; the pull rod positioned on the left side penetrates through the second annular plate axial through hole and is in clearance fit with the through hole, the two ends of the pull rod are respectively locked with the axial through holes in the end surfaces of the first annular plate and the third annular plate to form the coaxial movement structure of the auxiliary bellows compensator positioned at the left end and the main bellows compensator; and the pull rod positioned on the right side is staggered with the first annular plate and the same connection is performed so as to form the coaxial movement structure of the auxiliary bellows compensator positioned at the right end and the main bellows compensator. The high-pressure balanced compensator remarkably enhances the whole rigidity of the bellows compensators, avoids the plastic deformation and is particularly suitable for matching of pulverized coal pipelines.
Description
Technical field
The utility model relates to a kind of pipe safety device, and specifically, the utility model relates to a kind of high-pressure balancing type compensator.
Background technique
The fuel that modern big-and-middle-sized coal fired boiler uses mainly is coal dust, according to industry correlation technique code requirement, the necessary configuring pipes safety installations of pulverized coal conveying pipeline to eliminate pipeline because of end thrust and axial displacement that temperature variation produces, avoids occuring the pipeline security incident.Common configuration high-pressure balancing type compensator in the pulverized coal conveying pipeline, such compensator is take bellows as compensating element, and overall structure is simple, compensation is flexible, use is reliable.Traditional corrugated expansion joint structure characteristic clearly, it takes full advantage of end thrust and the axial displacement that institute's connecting tube was eliminated or absorbed to the bellows flexibility.Prior art adopts many corrugated expansion joint axial series linkage structures in order to increase the corrugated expansion joint flexibility.Facts have proved that many corrugated expansion joint axial series can accomplish the end in view, the corrugated expansion joint unstability easily causes bellows to damage in the pipeline configuration rigidity, particularly installation process but also significantly reduce.
The model utility content
The utility model is mainly for the deficiencies in the prior art, proposes a kind of simple in structure, operation freely, neither reduces the flexibility of corrugated expansion joint, can accomplish that again bellows does not produce the high-pressure balancing type compensator of excessive deformation.
The utility model is achieved through the following technical solutions technical goal.
High-pressure balancing type compensator, it is by being attached to the axial craspedodrome guide rail on the corrugated expansion joint and being positioned at 3 corrugated expansion joints of flange coaxial series connection at two ends, and the ring flat-plate that radially is fixedly connected with on the two pipe nipple outer walls, pull bar mix proportion.The corrugated expansion joint structure of described 3 axial series is identical, and the main corrugated expansion joint bore in the middle of being positioned at is large, and the secondary corrugated expansion joint bore that is positioned at both sides is identical but less than main corrugated expansion joint.Its improvements are: radially be fixedly connected with respectively ring flat-plate on the adapter outer wall at described two ends, uniform 6～24 axial holes on the ring flat-plate end face, the pull bar that is positioned at the left side runs through the 2nd ring flat-plate axial hole and makes Spielpassung, the pull bar two ends respectively with the 1st ring flat-plate and the 3rd ring flat-plate end face on axial hole do the spiral lock stressed joint, consist of the secondary corrugated expansion joint and the coaxial moving structure of main corrugated expansion joint that are positioned at left end.The pull bar that is positioned at the right side runs through the 3rd axial hole and makes Spielpassung, the pull bar two ends respectively with the 2nd ring flat-plate and the 4th ring flat-plate end face on axial hole do the spiral lock stressed joint, consist of and be positioned at the secondary corrugated expansion joint of right-hand member and the coaxial moving structure of main corrugated expansion joint.
The utility model compared with prior art has following good effect:
1, axial series is simple in structure, makes easily;
2, under ring flat-plate and pull bar constraint, significantly strengthen the rigidity of corrugated expansion joint, two groups of coaxial moving structures can move alone, also can move in the same way.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is Figure 1A place partial enlarged drawing.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and in conjunction with the embodiments for the below.
High-pressure balancing type compensator shown in Figure 1, it is by the axial craspedodrome guide rail that is attached on the corrugated expansion joint, with 3 corrugated expansion joints of flange 1 coaxial series connection that are positioned at two ends, and the ring flat-plate 3 that radially is fixedly connected with on two pipe nipples, 2 outer walls, pull bar 4 mix proportions.The corrugated expansion joint structure of above-mentioned 3 axial series is identical, but size is different, the more main corrugated expansion joint of bore in the middle of being positioned at, and the secondary corrugated expansion joint bore that is positioned at both sides is identical but less than main corrugated expansion joint.The utility model radially is fixedly connected with respectively ring flat-plate 3 on adapter 2 outer walls at secondary corrugated expansion joint two ends, dispose 6～24 axial holes according to secondary corrugated expansion joint bore on ring flat-plate 3 end faces.The secondary corrugated expansion joint bore of present embodiment is φ 300mm, uniform 8 axial holes on ring flat-plate 3 end faces.Pull bar 4 is the link in the utility model, it also is the track of guiding usefulness, the pull bar 4 that is positioned at the left side runs through the 2nd ring flat-plate 3 axial holes and makes Spielpassung, pull bar 4 two ends respectively with the 1st ring flat-plate 3 and the 3rd ring flat-plate 3 end face on axial hole do the spiral lock stressed joint, consist of the secondary corrugated expansion joint and the coaxial moving structure of main corrugated expansion joint that are positioned at left end.The pull bar 4 that is positioned at the right side is also done corresponding the connection, be that pull bar 4 runs through the 3rd ring flat-plate 3 axial holes and makes Spielpassung, pull bar 4 two ends respectively with the 2nd ring flat-plate 3 and the 4th ring flat-plate 3 end face on axial hole do the spiral lock stressed joint, consist of and be positioned at the secondary corrugated expansion joint of right-hand member and the coaxial moving structure of main corrugated expansion joint.The utility model utilizes pull bar 4 and ring flat-plate 3 to connect to form two groups of nose balance structures, except accomplishing to move alone and in the same way operation, also realize strengthening the integral rigidity of corrugated expansion joint, guarantee that bellows flexibility in scope of design moves axially, and avoids producing plastic deformation.
