Description
Technical field
The present invention relates to fluid product swivel technical field, more particularly to high-performance double seals swivel joint.
Background technology
Swivel joint of the present invention, for connecting rigid conduit, allows to be located at the pipeline phase on swivel joint both sides
To rotating.Fluid media (medium) in pipeline, during the pipeline of another side can be flowed into by swivel joint from the pipeline on one side.Use extensively
In the conveying equipment for fluid substances of 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 for rotating, and hollow rotating shaft is rotated in axle sleeve, so as to realize the connection of rotated pipe and fixed -piping.By
Need to be rotated relative to axle sleeve in hollow rotating shaft, fluid is conveyed in hollow rotating shaft, in order to prevent being flowed between hollow rotating shaft and axle sleeve
Body is leaked, 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 of times, sealing ring easily grinds
Damage, leakage occur, the medium for leaking out can often corrode seal again, accelerate seal aging, accelerate abrasion.At present, one
As swivel joint all there is this shortcoming.
Due to this shortcoming, cause that swivel joint will be changed at regular intervals or change sealing ring, waste time and energy；
And there is fluid for a long time in general fluid line, change the fluid that swivel joint must be just removed in pipeline, equipment needs
Stop operation.
Therefore, for the transmission equipment of dangerous, harmful fluids, the swivel joint for being used, 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 use in because sealing surface wear is produced
Leakage rate.
For example：Chinese Patent Application No. CN201410510214.3, it is open（Bulletin）Number:CN104344124A, discloses
A kind of rigid rotating joint, discloses a kind of swivel joint for oil filling riser, including outer ring, inner ring and flange, and outer ring is 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, outward
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, is effectively increased the sealing property of swivel joint, 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 is by by the gap between inside and outside circle
Leakage, the program be mounted with inner ring secondary seal ring for stop leakage.But the secondary seal ring is easier senile abrasion,
During primary seal is worn and torn, 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 of times, easily produce leakage.For the transmission of dangerous, harmful fluids, the structure is close
Sealing property is not high enough, also not durable enough.
The content of the invention,
Sealing property is not high enough between hollow rotating shaft and axle sleeve in order to overcome in swivel joint of the prior art for the present invention, easily
The deficiency for causing fluid to leak, there is provided initial sealing is higher between a kind of hollow rotating shaft and axle sleeve, sealing ring mill in use
Wear extent can be automatically compensated during damage, the swivel joint with high sealing performance.
The technical solution adopted by the present invention is as follows：
High-performance double seals swivel joint, including hollow rotating shaft, the left end of the hollow rotating shaft are mounted in axle sleeve internal holes,
Steel ball is provided between hollow rotating shaft and axle sleeve, enables hollow rotating shaft circumferentially rotated relative to axle sleeve, hollow rotating shaft
Right-hand member is provided with connector, and clamp sleeve is provided between the axle sleeve and connector, and the axle sleeve, connector and clamp sleeve pass through
Mode connects for screw；Cavity, and built-in first backbone sealing ring and the second backbone sealing ring are provided with inside the connector and axle sleeve, are pressed
Two sides of tight sleeve are pressed on two backbone sealing rings in the endoporus of connector and axle sleeve.
Further, connector is close on the first backbone sealing ring right side, and the right flank of clamp sleeve is close in left side；It is empty
Heart rotating shaft is provided with flange, and the right flank of the second backbone sealing ring, the left surface of the second backbone sealing ring are close on the left of flange
It is close to axle sleeve.
Further, the steel ball is set to two rows.
Further, the clamp sleeve uses static seal clamp sleeve.
Further, the both sides of the steel ball are provided with O-ring seals.
Further, the backbone sealing ring is made up of metallic framework, sealing ring body two.
Further, the angle that the endoporus of connector is formed with the endoporus of hollow rotating shaft is no more than 90 degree.
Further, it is additionally provided with plug screw on the axle sleeve.
The invention has the advantages that：
Using double seals technology, the sealing property of swivel joint is set to be greatly improved, and simple structure；Two dynamic sealings
After face is worn, can automatic compensating wear extent；For the transmission of dangerous, harmful fluids, security is improve, reduced
Environmental pollution.
Two backbone sealing rings are set in swivel joint, by the static seal clamp sleeve of special design reinforced seal
Circle is pressed in axle sleeve and connector inner chamber, improves the hollow Rotating shaft strocture of swivel joint, sets special outside hollow rotating shaft
The flange of door, for compressing the second sealing ring, and forms dynamic sealing with the second sealing ring.
By size design, the dynamics for making static seal clamp sleeve compress backbone sealing ring compresses skeleton more than hollow rotating shaft
The dynamics of sealing ring；Static seal clamp sleeve forms twice static seal, hollow rotating shaft and reinforced seal cast with backbone sealing ring
Into twice dynamic sealing；After two backbone sealing rings produce abrasion, the part being compacted can resilience, automatic compensating wear extent.
