Description
Technical field
The utility model is related to a kind of Yankee cylinder steam swivel joint end ring mechanisms.
Background technology
Yankee cylinder steam swivel joint end ring mechanism is widely used in tobacco manufacture field, Yankee cylinder steam swivel joint end
Ring mechanism generally comprises end ring flange, fixed end base, graphite-seal ring, flange seal ring, end ring flange rear end and fixing end
It is fixed between seat, by graphite-seal ring fitted seal between end ring flange front end face and flange seal ring, end ring flange be by
What carbon steel material was process, end ring flange and graphite-seal ring can rub during Yankee cylinder is run.
During shutdown, the end ring flange that carbon steel material can be corroded since remaining steam can be contained in pipeline, end ring method
Blue and graphite grazing loop interface, which forms rust spot, becomes uneven, and end ring pedestal rust spot will be in stone when Yankee cylinder is run again
It causes many cuts, steam that will be come out from cut clearance leakage on ink, causes the waste of steam and the corrosion of ambient enviroment.It must
The graphite-seal ring of damage must be replaced, end ring pedestal is repaired and replaced.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of Yankee cylinder steamings reasonable for structure, reducing maintenance cost
Vapour rotary joint end ring mechanism.
In order to solve the above technical problems, the utility model provides a kind of Yankee cylinder steam swivel joint end ring mechanism, packet
End ring flange, fixed end base, graphite-seal ring, flange seal ring are included, fixed between end ring flange rear end and fixed end base, end
Pass through graphite-seal ring fitted seal between ring flange front end face and flange seal ring；
End ring flange includes end ring ontology, sealing ring and end face sealing ring, and end face sealing ring is arranged with end ring ontology inner ring
Between end ring ontology and end face sealing ring, end face sealing ring front end face contacts sealing with graphite-seal ring.
After such structure, end ring flange is only contacted by end face sealing ring with graphite-seal ring, if end face is close
Seal ring damage or end face sealing ring and graphite-seal ring between it is poorly sealed when, can only orientation replace end face seal
Ring, without all replacing entire end ring flange body；Sealing ring also can guarantee between end ring ontology and end face sealing ring
Leakproofness does not influence the normal use of end ring flange.
For the clearer technology contents for understanding the utility model, below by this Yankee cylinder steam swivel joint end ring machine
Structure is referred to as local terminal ring mechanism.
The end ring ontology endoporus front of local terminal ring mechanism is equipped with screw thread, the end ring ontology endoporus side wall on rear side of the screw thread to
It is inside extended with projecting ring section, projecting ring section front end face is provided with the seal groove for accommodating sealing ring；End face sealing ring rear portion outer wall is equipped with and end
The screw thread of ring body inner hole, end face sealing ring front external part ring body endoporus front side；It, can be with after such structure
Facilitate and be connected and fixed between end ring ontology and end face sealing ring, and the setting of seal groove can make end face sealing ring rear end face tight
It is close to be contacted with sealing ring, it is ensured that the end ring flange leakproofness of itself.
The material of the end face sealing ring of local terminal ring mechanism is tin bronze；After such structure, tin bronze material will not
It gets rusty because of contact steam, while tin bronze hardness is big, there is relatively very high wearability.
The fixed end base edge of local terminal ring mechanism is fixed with several axis pins, if end ring ontology corresponds to several axis pin positions and is provided with
Dry location hole, the end part of pin shaft stretch out on front side of location hole, are set with spring on every axis pin, spring one end is resisted against fixing end
On seat, plays the other end and be resisted against on end ring ontology；After such structure, axis pin can with the telescopic direction of limited spring,
When graphite-seal ring is worn, spring can apply active force with opposite end ring flange, and end ring flange is made to remain to graphite-seal ring
Compressing, ensure to pass through graphite-seal ring fitted seal between end ring flange front end face and flange seal ring.
Description of the drawings
Fig. 1 is the exploded view of local terminal ring mechanism embodiment.
Fig. 2 is the sectional view of local terminal ring mechanism embodiment end ring ontology.
Specific implementation mode
As shown in Fig. 1 to 2.
Local terminal ring mechanism includes 8,12 end ring flange, fixed end base 4, graphite-seal ring 7, flange seal ring axis pins 5
With 12 springs 6.
Fixed end base 4 is generally circular, and 4 edge of fixed end base is provided with 12 uniform circular distributions along its axis direction
Through-hole, 12 axis pins 5 fix with the cooperation of 12 through-holes respectively, axis direction and the fixed end base 4 of 12 axis pins 5
Axial direction is consistent, and 12 axis pins 5 forward extend out.
End ring flange includes end ring ontology 1, sealing ring 2 and end face sealing ring 3, and end ring ontology 1 is generally tubular, end ring sheet
Ring flange 1c is extended on 1 front outer wall of body, 1 rear sleeve of end ring ontology is in 4 endoporus of fixed end base, the method for end ring ontology 1
Blue disk 1c corresponds to 12 5 positions of axis pin and is provided with 12 location hole 1e, before corresponding location hole 1e is stretched out in every 5 end of axis pin
Side, 1 endoporus front end of end ring ontology be equipped with screw thread 1a, the 1 endoporus side wall of end ring ontology on rear side of screw thread 1a extend internally have it is convex
Ring portion 1d, projecting ring section 1d front end faces are provided with the seal groove 11b for accommodating sealing ring 2；
3 rear portion outer wall of end face sealing ring is equipped with the screw thread with 1 inner hole of end ring ontology, and sealing ring 2 is placed on seal groove
In 1b, end face sealing ring 3 coordinates with 1 inner hole thread of end ring ontology, and 3 rear end face of end face sealing ring is resisted against on sealing ring 2, seals
Sealing between 2 realization end ring ontology 1 of circle and end face sealing ring 3,3 front external part ring body of end face sealing ring, 1 endoporus front side,
3 front end face of end face sealing ring is used to contact sealing with graphite-seal ring 7.
Spring 6 is set on every axis pin 5,6 one end of spring is resisted against on fixed end base 4, is played the other end and is resisted against end ring
The ring flange 1c of ontology 1, when graphite-seal ring 7 is worn, still opposite end ring flange applies active force to spring 6, makes end ring flange
It remains the compressing to graphite-seal ring 7, ensures to pass through graphite-seal ring between end ring flange front end face and flange seal ring 8
7 fitted seals.
Above-mentioned end ring flange and fixed end base 4 are pressed in as the static part of steam rotary union on graphite-seal ring 7, stone
The flange seal ring 8 of black sealing ring 7 and rotary joint rotating part contacts；
When Yankee cylinder rotates, graphite-seal ring 7 plays sealing function, graphite grazing between dynamic part and static part
Ring 7 will produce certain abrasion in moving, and is process using tin bronze material due to end face sealing ring 3 when shutting down, will not
It gets rusty because of contact steam, while tin bronze hardness is big, there is relatively very high wearability, rotary joint is during use
Steam leakage and component will not be caused to be easily damaged phenomenon.
Above-described is only a kind of embodiment of the utility model, it is noted that for the ordinary skill of this field
For personnel, without departing from the principle of this utility model, several variations and modifications can also be made, these also should be regarded as
Belong to the scope of protection of the utility model.
