Description
Technical field
The utility model is related to sealing machine equipment technical field, more particularly to a kind of sealing ring and is provided with the sealing
The telescoping tube and rotary flange of circle.
Background technology
The extensive use in a variety of plant equipment of inflation sealing ring, but traditional sealing ring is generally hollow envelope
Enclosed circular ring structure.In the prior art, drainage car, fire fighting truck etc. need to extend to pipeline into the plant equipment of specified location
On, in order to the length of flexible control piper, it is typically necessary using the telescoping tube being made up of outer tube and inner tube, outer tube and interior
Sealing ring is provided between pipe；In addition, sealing ring is applied in rotary flange etc. has relative rotary motion slewing
Widely, it makes it be rotated in unaerated, sealed during inflation generally using the sealing of gas-flow closure circle.However, sealing ring is
A kind of consumable accessory is, it is necessary to often change, and the especially installation in large-scale, cumbersome apparatus is more cumbersome with changing program, work
Amount is big, and labor intensity is high, and disassembling, assembling and replacing is extremely inconvenient.
For example, in order to reduce frictional resistance when telescoping tube stretches between outer tube wall and outer wall of inner tube, China is practical new
Type patent discloses the telescoping tube of Patent No. 201420548808.9, and it includes inner tube, outer tube, interior rolling member, outer rolling part
And seal, the outer tube sleeve forms gap between the outside of inner tube, the outer tube and inner tube, and inner tube can be by outer tube
Outer tube is stretched out in front end, and the outer rolling part is circumferentially arranged in outer tube front end, and its rolling surface is contacted with outer wall of inner tube, described close
Sealing is located in gap, and can be by clearance seal.The telescoping tube of this kind of structure, although the direct of inner tube and outer tube can be avoided
Contact, is greatly reduced frictional force, reduces pipe wear and deformation probability, however, because it is by seal and outer rolling part installation position
The limitation put, seal when changing, it is necessary to first dismounting positioned at outer tube front end outer rolling part, then by inner tube rear end before outer tube
End is detached, and is driven the disengagement of seal member gap being set on outer wall of inner tube, is then pulled down old seal from inner tube rear end, then
From inner tube rear end, set changes new seal, and finally inner tube rear end is installed back in outer tube and installed back the outer rolling part pulled down outer
Pipe front end, therefore, the disassembling, assembling and replacing method of this kind of seal are extremely inconvenient.
For another example, Chinese utility model patent discloses a kind of rotary flange of Patent No. 201420550591.5, and it is extremely
Include rotating mechanism and sealing mechanism less, the rotating mechanism possesses the base and rotary body of tubular, the base and the rotation
Swivel is rotated coaxially, and possesses gap, the gap one end open, the sealing mechanism tool between the base and the rotary body
Standby compressed part and elastomeric seal portions, the elastomeric seal portions possess elastic seal ring, and the elastomeric seal portions are located at the gap
In, and to be connected by loosening certainly under original-shape with the base and/or the rotary body, to release to the seam
Gap plays the mode of sealing effectiveness and the gap coordinates.The rotary flange of this kind of structure, the installation of its sealing mechanism is with changing ten
Divide cumbersome.
