Description
Technical field
Fluid product swivel technical field is the utility model is related to, more particularly to high-performance double seals rotation connects
Head.
Background technology
The swivel joint that the utility model is related to, for connecting rigid conduit, make the pipeline positioned at swivel joint both sides can
To relatively rotate.Fluid media (medium) in pipeline, it can be flowed into from the pipeline on one side by swivel joint in the pipeline of another side.Extensively
The general conveying equipment for fluid substances for every profession and trade.
Swivel joint generally comprises hollow rotating shaft, axle sleeve, a connector, and connector is connected with fixed pipeline, hollow
Rotating shaft is connected with the pipeline rotated, and hollow rotating shaft rotates in axle sleeve, so as to realize the connection of rotated pipe and fixed -piping.By
Need to rotate relative to axle sleeve in hollow rotating shaft, fluid conveys in hollow rotating shaft, in order to prevent flowing between hollow rotating shaft and axle sleeve
Body leaks, and needs to install sealing ring between hollow rotating shaft periphery and axle sleeve.Most swivel joints, sealing property is all not bery high, right
In the fluid transmission for having certain pressure, it is easy to produce leakage.In addition, after hollow rotating shaft rotates certain number, sealing ring is easily ground
Damage, is leaked, the medium leaked out, can often corrode seal again, accelerates seal aging, accelerates abrasion.At present, one
As swivel joint this shortcoming all be present.
Due to this shortcoming, cause that swivel joint will be changed at regular intervals or change sealing ring, waste time and energy；
And fluid in general fluid line for a long time be present, replacing swivel joint must just remove the fluid in pipeline, and equipment needs
Stop operation.
Therefore, for dangerous, harmful fluids transmission equipment, used swivel joint, it is accordingly required in particular to improve the close of it
Sealing property.Focus on improving the initial sealing between hollow rotating shaft and axle sleeve, reduce in use because sealing surface wear produces
Leakage rate.
Such as：Chinese Patent Application No. CN201410510214.3, open (bulletin) number:CN104344124A, disclose
A kind of rigid rotating joint, a kind of swivel joint for oil filling riser is disclosed, including outer ring, inner ring and flange, outer ring are sheathed on
Inner ring, inner ring can be connected relative to outer ring axial rotation, outer ring with flange, primary seal circle is provided between inner ring and flange, outside
Secondary seal ring is provided between circle and inner ring, thus, can be prevented because sealing surface produces seam after operating abrasion for a long time at sealing ring
Gap, the sealing property of swivel joint is effectively increased, improves service life.But the sealing property of this structure is still not
Enough height, between primary seal and inner ring end face after rubbing after a while, the fluid of leakage will pass through the gap between inside and outside circle
Leakage, the program be mounted with inner ring secondary seal ring be used for stop leakage.But the secondary seal ring is easier senile abrasion,
During primary seal is worn, secondary seal ring also produces abrasion simultaneously, and the structure can not compensate secondary seal ring wear extent.In use
It was found that after this swivel joint rotates certain number, leakage is easily produced.It is close for dangerous, harmful fluids transmission, the structure
Sealing property is not high enough, also not durable enough.
