Abstract
A low-temperature rotary joint used for fluid delivery comprises an inner ring and an outer ring. A steel ball raceway is arranged between the inner ring and the outer ring; and steel balls are arranged in the steel ball raceway; a left end of the outer ring is connected with an outer ring flange; and a right end of the inner ring is connected with an inner ring flange; a lining jacket is arranged inside the inner ring; an isolating cavity is arranged between an outer wall of the lining jacket and an inner wall of the inner ring; a primary seal device I is arranged between a left end of the lining jacket and the outer ring flange; and a primary seal device II is arranged between a right end of the lining jacket and the inner ring flange. The steel ball raceway is provided with a nitrogen cycle blowing and sweeping mechanism such that nitrogen can bring away air, preventing the inner ring and the outer ring from being frozen. The rotary joint adopts a double-seal structure; and the isolating cavity arranged between the lining jacket and an inner jacket can isolate most low temperature. It is can be ensured that the contraction of the liner jacket in a low-temperature condition does not affect the inner ring. The low-temperature rotary joint is advantageous in compact structure, long service life and favorable seal effect.
Description
Technical field
The utility model relates to a kind of liquid loading and unloading technology, and particularly a kind of liquid is carried and used the low temperature swivel joint.
Background technique
The low temperature swivel joint is the chief component of low temperature arm, and its technology is the core technology of low temperature arm.At present, rare, LNG of fed sheet of a media such as liquid oxygen, liquid etc. must use the low temperature arm to load and unload.Because this type of medium is all subzero below 100 ℃, therefore common liquid handling arm can not satisfy use, and the normal temperature arm just leaks under the situation of this kind low temperature.Now the structure of the swivel joint of normal temperature is the individual layer seal ring, in addition, in the steel ball rolling channel of normal temperature arm between inner ring and outer ring because air is arranged; Airborne moisture can freeze under low temperature condition; Steel ball is frozen, make it to rotate and lose function, working life is short.
Summary of the invention
The technical problem that the utility model will solve is the deficiency to existing technology, and the low temperature swivel joint is used in the liquid conveying that has proposed a kind of compact structure, long service life, good sealing effect.
The technical problem that the utility model will solve realizes that through following technological scheme a kind of liquid is carried and used the low temperature swivel joint, comprises inner ring and outer ring; Between inner ring and outer ring, be provided with steel ball rolling channel; Steel ball is housed in the steel ball rolling channel, and the left end of outer ring is connected with the outer ring flange, and the right-hand member of inner ring is connected with the inner ring flange; Be characterized in: in inner ring, be provided with lining; Between the inwall of the outer wall of lining and inner ring, be provided with the isolation cavity, be provided with the main sealing device I between the left side of lining and the outer ring flange, be provided with the main sealing device II between the right side of lining and the inner ring flange.
The technical problem that the utility model will solve can also further realize through following technological scheme; Steel ball rolling channel between inner ring and the outer ring is provided with the nitrogen circulation blowing mechanism; The nitrogen circulation blowing mechanism comprises the nitrogen inlet that is located on the inner ring; Nitrogen inlet communicates with steel ball rolling channel, on the outer ring, has nitrogen outlet, and nitrogen outlet communicates with steel ball rolling channel.
The swivel joint of the utility model is a double-layer seal, has inlayed lining at inner ring.This lining directly contacts with medium, between lining and interior cover, the isolation cavity is arranged, and low like this temperature will be isolated greatly.Lining shrinks under the situation of low temperature, but does not influence inner ring.In addition, through the nitrogen circulation blowing mechanism, between Internal and external cycle, be full of nitrogen all the time, nitrogen can be taken away air, and the unlikely Internal and external cycle that makes freezes.When Internal and external cycle produced relative rotation, cryogenic media can not let out the slit between Internal and external cycle under the effect of seal ring.When wearing and tearing take place when, can take out grinding and polishing to lining, so just can prolong the working life of swivel joint.The utility model compared with prior art, compact structure, long service life, good sealing effect.

A kind of liquid is carried and is used the low temperature swivel joint; Comprise inner ring 6 and outer ring 3, between inner ring 6 and outer ring 3, be provided with steel ball rolling channel, steel ball 5 is housed in the steel ball rolling channel; The left end of outer ring 3 is connected with outer ring flange 1; The right-hand member of inner ring 6 is connected with inner ring flange 8, in inner ring 6, is provided with lining 10, between the inwall of the outer wall of lining 10 and inner ring 6, is provided with to isolate cavity 11; Be provided with main sealing device I 2 between the left side of lining 10 and the outer ring flange 1, be provided with main sealing device II 7 between the right side of lining and the inner ring flange 8.
Steel ball rolling channel between inner ring 6 and the outer ring 3 is provided with the nitrogen circulation blowing mechanism; The nitrogen circulation blowing mechanism comprises the nitrogen inlet 9 that is located on the inner ring; Nitrogen inlet 9 communicates with steel ball rolling channel, on the outer ring, has nitrogen outlet 4, and nitrogen outlet 4 communicates with steel ball rolling channel.
The swivel joint of the utility model is a double-layer seal, between inner ring and the outer ring, between outer ring and the outer ring flange, be provided with between inner ring and the inner ring flange and be equipped with secondary seal arrangement, constitute outer sealing; Main sealing device I between the two ends of lining and the inside and outside circle flange, main sealing device II constitute the internal layer sealing.
Through the nitrogen circulation blowing mechanism, between Internal and external cycle, be full of nitrogen all the time, nitrogen can be taken away air, and the unlikely Internal and external cycle that makes freezes.
On material, select the low temperature material stainless steel to do the Internal and external cycle and the flange of swivel joint in addition, add other affix with teflon and make low temperature resistant seal ring.Inner ring can also be changed, and increases the working life of swivel joint.
