Technical field
The present invention relates to a kind of pipe safety device, in particular it relates to a kind of straight tube bypass pressure balanced type
FlexbleJoint, particularly a kind of sleeve anti-corrosion straight tube bypass pressure balance type bellows compensator.
Background technology
Oil tanker is typically the super large marine that number picks up ten thousand tons, and its berth is deep water port, nevertheless, the crude oil code at harbour
Head, which must configure access bridge piping lane, could dock oil tanker oil pipeline interface.Positioned at seashore harbour because air humidity it is big, Er Qiehai
Wind is more containing salinity, and corrosion easily occurs in high humidity, high salt mist environment for access bridge piping lane that is outdoor and building.Straight tube bypass pressure balanced type
FlexbleJoint is the safety device in access bridge piping lane, and its running quality determines the safety in utilization of access bridge piping lane, straight in structure
Pipe bypass pressure balance type bellows compensator mainly undertakes nose balance, and counter balance pocket internal volume changes at random in compensation process, is
Accomplish timely release, counter balance pocket is by the respiratory siphon air-breathing overhang or exhaust.Bellows is in straight-through air during stretching shape
Respiratory siphon suction air, high humidity, high salt fog air in this seaport environment form etching condition to compensating element, inwall, held
It is continuous to use necessarily initiation chlorion stress corrosion.Therefore, the straight tube bypass pressure balance type bellows compensator of prior art uses
In major safety risks be present, once occur corrosion wall-through damage just cause access bridge piping lane failure, crude oil leakage directly pollutes code
Head.
The content of the invention
Present invention is generally directed to the exposed deficiency of the prior art products configuration respiratory siphon mouth of pipe, propose it is a kind of it is simple in construction,
Sealing is tight, the sleeve anti-corrosion straight tube bypass pressure balance type bellows compensator built in the respiratory siphon mouth of pipe.The structural arrangement
Respiratory siphon is in specific preserving and sealing structure, can avoid sucking corrosive atmosphere in motion process, so as to improve product operation
Reliability and security.
The present invention is achieved through the following technical solutions technical goal.
Sleeve anti-corrosion straight tube bypass pressure balance type bellows compensator, it is by FlexbleJoint and telescopic sealing structure
Collectively constitute.The FlexbleJoint includes adapter, respiratory siphon, work bellows, shell, balance bellows and inner tube.It is described
Telescopic sealing structure, which is located at FlexbleJoint, one end of work bellows, and it includes end ring plate, outer sleeve, sealing ring, pressure
Collar, spring, bolt assembly and inner sleeve.The improvement is that：The inner sleeve is that a section is connected with shell co-axial seal
Pipe, the cantilever end outer wall of inner sleeve are provided with one of radial direction annulus.The end ring plate is sealedly connected on adapter stage casing outer wall,
The end ring plate radial direction annulus preset with inner sleeve is coaxial, and outer sleeve one end of outer fit is tightly connected with end ring plate, the other end with
The preset radial direction ring gap of inner sleeve coordinates, and forms the cavity of enclosure respiratory siphon.Radial seal connects on the overcoat drum outer wall
The regulating tube linked up inside and outside cavity is connect, the flange of uniform axially extending bore together is fixedly connected with the adjacent side of regulating tube, outside
Plug fills one group of sealing ring between sleeve and inner sleeve shrinking section.The compacting ring is sleeved on inner sleeve drum outer wall, and compacting ring is provided with
With the axially extending bore of outer sleeve flange pairing.Bolt assembly and the spring pairing is through compacting ring and the flange of outer sleeve
Side, screwing bolts component form the telescopic sealing structure by elastic compression.
As further improvement project, the radial direction annulus external diameter on the end ring plate external diameter and liner pipe outer wall is equal.
As further improvement project, the regulating tube lowest calibre is more than the maximum caliber of respiratory siphon.
As further improvement project, the sealing ring is Y profile shaft sealings, and it is one group of installation by 8~10.
As further improvement project, the sealing ring is polytetrafluoroethylene (PTFE) or ternary second is bright or polyurethane material product.
The present invention compared with prior art, has the positive effect that：
1st, the telescopic sealing structure set up is simple, and it is easy to make；
2nd, telescopic sealing structure and FlexbleJoint coaxial cooperation, on the premise of FlexbleJoint normal operation is not influenceed,
Dramatically increase compensator structure rigidity and stability；
3rd, respiratory siphon is among telescopic sealing structure, can accomplish that tidal air is quality controllable, avoids the high salt fog air of high humidity from entering
Enter compensating element, inwall, avoid producing chlorion stress corrosion, therefore greatly improve the service life of FlexbleJoint.
Brief description of the drawings
Fig. 1 is structural profile illustration of the present invention.
Embodiment
Below according to accompanying drawing and in conjunction with the embodiments, the invention will be further described.
Sleeve anti-corrosion straight tube bypass pressure balance type bellows compensator shown in Fig. 1, it is by FlexbleJoint and sleeve
Formula sealing structure collectively constitutes.The FlexbleJoint includes adapter 1, respiratory siphon 3, work bellows 10, shell 11, balance wave
Line pipe 12 and inner tube 13.The telescopic sealing structure, which is located at FlexbleJoint, one end of work bellows 10, and it includes end
Ring flat-plate 2, outer sleeve 4, sealing ring 5, compacting ring 6, spring 7, bolt assembly 8 and inner sleeve 9.The inner sleeve 9 is for a section and outside
The pipe of the co-axial seal of shell 11 connection, the cantilever end outer wall of inner sleeve 9 are provided with one of radial direction annulus.The end ring plate 2 seals
It is connected on the stage casing outer wall of adapter 1, the radial direction annulus preset with inner sleeve 9 of end ring plate 2 is coaxial, and diameter is equal, outer fit
