Order, including according to involved function by it is basic at the same time in the way of or in the opposite order, carry out perform function, this should be by this
The embodiment person of ordinary skill in the field of utility model is understood.
As shown in Figure 1, the utility model provides a kind of high temperature rotary joint, including housing 1 and outer tube 2, the housing 1
In be provided with the first inner chamber 3 that left and right end face is connected, there is the first interface to connect with pipeline at the 1 nearly left side of housing
4, the second inner chamber 5 that left and right end face is connected is provided with the outer tube 2, is had at the 2 nearly right side of outer tube and pipeline phase
The second interface 6 connect, closely at the left side of the outer tube 2, is provided with sealed spheroid 7, the sealing on the outer wall of the outer tube 2
The shape of sphere 7 is outer sphere, and the sealed spheroid 7 is inserted into the first inner chamber 3 by right end；In the first inner chamber 3,
The left end of the sealed spheroid 7 is provided with left seal receptacle 8, and right end is provided with right seal receptacle 9；The left seal receptacle 8 and right sealing
Outer wall of the inner hole wall of seat 9 with the sealed spheroid 7 is bonded, and the inner hole wall shape of the left seal receptacle 8 and right seal receptacle 9 is
With the matched interior spheroid of shape of the sealed spheroid 7；The left seal receptacle 8 is fixedly connected with first inner chamber 3；The housing
End cap 10 is provided with 1 right side, the end cap 10 is connected by clamp device with housing 1, the end cap 10 pushing tow to the left
The right seal receptacle 9 causes outer wall of the inner hole wall of right seal receptacle 9 and left seal receptacle 8 with the sealed spheroid 7 to be bonded to each other
Compress.
High temperature rotary joint is connected in extraneous pipeline by first interface 4 and second interface 6, one end connection rotating part
Pipeline, the pipeline of other end connecting portion point, the transmission medium such as fused salt, conduction oil or inert gas passes through first inner chamber
3 and second inner chamber 5 be transmitted.Left seal receptacle 8 and right seal receptacle 9 are tightly fitted in ball sealer under the pressuring action of end cap 10
On the outer wall of body 7, such outer tube 2 with rotary motion and be able to can keep sealing relative to housing 1, avoid 3 He of first inner chamber
The dielectric leakage transmitted in second inner chamber 5.Since left seal receptacle 8 and right seal receptacle 9 are to be contacted by spherical with sealed spheroid 7
, therefore, outer tube 2 can realize the beat of certain angle relative to housing 1, and can continue to ensure dynamic sealing effect, general feelings
This beat scope is within 15 ° under condition.
This structure sealed firmly avoids the limitation of conventional sealing material or compensation medium to temperature, therefore, can be with
Medium temperature is allowed to reach 600 °C, media operation pressure reaches 15bar, fully meets solar power system fused salt pipeline
Use demand.

The T-shaped face vertical with the outer wall surface of the sealed spheroid 7.Fused salt, which is easily formed, crystallizes and is attached to the sealing surfaces to contact with each other
Between, it is possible to inordinate wear even results in leakage between causing sealing surface, by left seal receptacle 8 and the endoporus of right seal receptacle 9
T-shaped face is done in wall cross section, has scraping function at the sharp edge chamfering in T-shaped face, can scrape the fused salt crystallization on sealing surfaces
Remove, avoid fused salt crystallization causes sealing surface to damage into sealing surface, ensure that the service life and sealing effect of sealing surface.
It is close positioned at the left seal receptacle 8 and the right side between the outer wall of the sealed spheroid 7 and the first inner chamber 3
Kollag 11 is filled between envelope seat 9.The kollag 11 is flexible graphite packing, this kollag 11 1
Aspect can be penetrated at sealing surface, and left seal receptacle 8 and right seal receptacle 9 are rubbed in gluing, sealing sphere 7 and keep sealing
When, kollag 11 can lubricate sealing surface and reduce the abrasion between this friction pair, further reduce friction resistance
Power simultaneously reduces the frictional heat generation between friction pair, this solid on the other hand by sealing surface in the event of small leak source
Such as flexible graphite packing of body lubricant 11 is filled in leak source in time, and the generation of leakage can be prevented in early period.It substantially prolongs
The service life of sealing surface and improve sealing reliability.
The clamp device includes bolt 12 and disc spring 13, and the bolt 12 is tightened on the housing through the end cap 10
On 1, the disc spring 13 fitting is pressed on the right side of the end cap 10 by the bolt 12.Bolt 12 is by screwing and unscrewing
The pressure being pressed in disc spring 13 can be changed, the pressure that can be so pressed on Indirect method end cap 10 on right seal receptacle 9, leads to
Crossing such mode can control left seal receptacle 8 and right seal receptacle 9 to be adjacent to the pressure on sealed spheroid 7 well, both can be with
Ensure the reliable of sealing, while can ensure that sealing surface will not be worn too quickly again.
The left seal receptacle 8 and the first inner chamber 3 are Split type structure, and the left seal receptacle 8 is fixedly mounted on described the
On the inner hole wall of one inner cavity 3.This structural elements are easy to process, and difficulty of processing is relatively low.It is also possible to use another kind side
Case, the left seal receptacle 8 and the first inner chamber 3 are overall structure, during using this structure, are processed at the same time within the case 1
Left seal receptacle 8 and first inner chamber 3, relative to first inner chamber 3 change in location will not occur for left seal receptacle 8, while can ensure very
High machining accuracy.
