Abstract
The invention discloses a high-pressure balanced compensator which is composed of three bellows compensators of the same structure, radially fixed annular plates and draw bars, wherein flanges at two ends are coaxially in serial connection with the bellows compensators, and two ends of the annular plates are connected with the outer wall. The caliber of the main bellows compensator in the middle is large, and the calibers of the two auxiliary bellows compensators on two sides are smaller than the caliber of the main bellows compensator. Six to twenty-four axial through holes are evenly formed in the annular plates, the draw bar on the left side penetrates the second annular plate and is in clearance fit with the second annular plate, and two ends of the draw bar on the left side are locked with the axial through holes in end surfaces of the first annular plate and the third annular plate to form a coaxial moving structure of the auxiliary bellows compensator at the left end and the main bellows compensator. The draw bar on the right side gets away from the first annular plate and is in the same connection so as to form a coaxial moving structure of the auxiliary bellows compensator at the right end and the main bellows compensator. The high-pressure balanced compensator remarkably enhances integral rigidity of the bellows compensators, prevents plastic deformation and is particular suitable for being matched with pulverized coal pipelines.
Description
Technical field
The present invention relates to a kind of pipe safety device, specifically, the present invention relates to a kind of high-pressure balancing type compensator.
Background technique
The fuel that modern big-and-middle-sized coal fired boiler uses is mainly 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, avoid occurring the pipeline security incident.Common configuration high-pressure balancing type compensator in the pulverized coal conveying pipeline, such compensator be take bellows as compensating element, and overall structure is simple, compensation is flexible, use is reliable.Traditional corrugated expansion joint structure characteristic clearly one, 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, in order to increase the corrugated expansion joint flexibility, adopts many corrugated expansion joint axial series linkage structures.Facts have proved that many corrugated expansion joint axial series can accomplish the end in view, but also significantly reduce corrugated expansion joint unstability in pipeline configuration rigidity, particularly installation process, easily cause bellows to damage.
Summary of the invention
The present invention 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 present invention is achieved through the following technical solutions technical goal.
High-pressure balancing type compensator, it is by being attached to axial craspedodrome guide rail on corrugated expansion joint and being positioned at 3 corrugated expansion joints of flange coaxial series connection at two ends, and the ring flat-plate radially be fixedly connected with on 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 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, form 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 right side runs through the 3rd axial hole and ring flat-plate is made 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, form and be positioned at the secondary corrugated expansion joint of right-hand member and the coaxial moving structure of main corrugated expansion joint.
The present invention 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.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is Figure 1A place partial enlarged drawing.
Embodiment
Below the invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments.
High-pressure balancing type compensator shown in Fig. 1, it is by the axial craspedodrome guide rail be attached on corrugated expansion joint, with 3 corrugated expansion joints of the coaxial series connection of the flange 1 that is positioned at two ends, and the ring flat-plate 3 radially be fixedly connected with on two pipe nipple 2 outer walls, pull bar 4 mix proportions.The corrugated expansion joint structure of above-mentioned 3 axial series is identical, but the size difference, the more main corrugated expansion joint of bore in the middle of being positioned at, the secondary corrugated expansion joint bore that is positioned at both sides is identical but less than main corrugated expansion joint.The present invention radially is fixedly connected with respectively ring flat-plate 3 on adapter 2 outer walls at secondary corrugated expansion joint two ends, on ring flat-plate 3 end faces, according to secondary corrugated expansion joint bore, configures 6～24 axial holes.The secondary corrugated expansion joint bore of the present embodiment is φ 300mm, uniform 8 axial holes on ring flat-plate 3 end faces.Pull bar 4 is the link in the present invention, it is also the track of guiding use, the pull bar 4 that is positioned at 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, form 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 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, form and be positioned at the secondary corrugated expansion joint of right-hand member and the coaxial moving structure of main corrugated expansion joint.The present invention 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 operation in the same way, also realizes strengthening the integral rigidity of corrugated expansion joint, guarantees that bellows flexibility in scope of design moves axially, and avoids producing plastic deformation.
