Abstract
The utility model relates to a mechanical device's seal structure, especially a carbocycle seal structure, it comprises gland (1), axle sleeve (3), stud (6), nut (7), carbocycle (9) and elastic medium (10), the utility model discloses among the technical scheme, a simple structure, safe and reliable, low cost's carbocycle seal structure is provided, simultaneously, because elastic medium makes carbocycle and axle sleeve sealed inseparabler, it is sealed to make it can replace the dry gas in some gaseous operating mode, has reduced the sealed cost of dry gas.
Description
Technical field
The utility model relates to a kind of sealing configuration for mechanical device, particularly a kind of carbon ring sealing structure.
Background technique
Carbon ring seal belongs to the one of floating seal, gains the name because its material is carbon.The structure of carbon ring seal comprises ring packing cavity and annular sleeve, the circular groove that quantity does not wait is had in seal chamber, the ring-shaped graphite seal ring that two cross sections are rectangle is at least housed in groove, certain gap is had between the internal diameter of graphite-seal ring and annular sleeve, under normal operation, floating ring and axle sleeve are in contactless state substantially, have annular sulculus at per pass carbocyclic ring inner face simultaneously, gas forms air whirl through sulculus at this and cuts off dielectric gas, reaches sealing purpose; Compared with traditional mechanical seal, it is advantageous that:
Traditional mechanical seal, most high-temperature resistant is about 400 DEG C, and the most high-temperature resistant value of carbon ring seal is about 700 DEG C;
Traditional mechanical seal rotating speed is subject to the impact of PV value, and general rotating speed is no more than 3600rpm, and the maximum speed of carbon ring seal can reach about 5000rpm.
At present, most of mechanical seal is all by perpendicular to one group of end face of axis, utilizes the axial force of spring to compensate, and a kind of structure of liquid film is stablized in generation, but it is not high also to there is complex structure, reliability, can not be used for carrying out the problem of dry gas seals completely.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of structure carbon ring sealing structure simple, safe and reliable, with low cost.
For solving the problems of the technologies described above, the utility model realizes as follows: design a kind of carbon ring sealing structure, and it is made up of gland, axle sleeve, stud, nut, carbocyclic ring and Elastic medium; Gland is hollow and annular; Be provided with axle sleeve at the inner wall of gland, axle sleeve is ring, the madial wall of axle sleeve and need the equipment sealed to be formed to contact and connect, and is provided with seal ring in the two contacting point; Described axle sleeve outer side wall and gland madial wall form recessed bond ing; Be provided with carbocyclic ring along gland inwall circumference, described carbocyclic ring is two lobes; Described in the outer ring of carbocyclic ring, carbocyclic ring and gland contacting point are provided with Elastic medium; Described gland is fixed by stud and nut; Axle sleeve is also provided with driving screw.
Further, also pad is provided with between described gland and nut.
Further, described gland is also provided with leak holes.
Further, the position that described axle sleeve contacts with gland is provided with seal ring.
Further, described axle sleeve madial wall is provided with axle sleeve O and encloses.
Good effect of the present utility model: in technical solutions of the utility model, provides the carbon ring sealing structure that a kind of structure is simple, safe and reliable, with low cost; Meanwhile, because Elastic medium makes the more tight of carbocyclic ring and sleeve sealing, make it can alternative dry hermetic seal in some simple gas operating mode, reduce the cost of dry gas seals.
Accompanying drawing explanation
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with embodiment and accompanying drawing, the utility model is described in further details.At this, exemplary embodiment of the present utility model and illustrating for explaining the utility model, but not as to restriction of the present utility model.
Fig. 1 is the structural representation of the utility model embodiment.
In figure, 1 gland 2 axle sleeve O encloses 3 axle sleeves
4 seal rings 5 drive screw 6 stud
7 nut 8 pad 9 carbocyclic rings
10 Elastic medium 11 leak holes
Embodiment
As shown in the figure, carbon ring sealing structure described in the utility model is made up of gland 1, axle sleeve 3, stud 6, nut 7, carbocyclic ring 9 and Elastic medium 10; Gland 1 is hollow and annular; Be provided with axle sleeve 3 at the inner wall of gland 1, axle sleeve 3 is ring, the madial wall of axle sleeve 3 and need the equipment sealed to be formed to contact and connect, and is provided with seal ring 4 in the two contacting point; Described axle sleeve 3 outer side wall and gland 1 madial wall form recessed bond ing; Be provided with carbocyclic ring 9 along gland 1 inwall circumference, described carbocyclic ring 9 is two lobes; Described in the outer ring of carbocyclic ring 9, carbocyclic ring 9 and gland 1 contacting point are provided with Elastic medium 10; Described gland 1 is fixed by stud 6 and nut 7; Axle sleeve 3 is also provided with and drives screw 5.
Further, more firm in order to what gland 1 was fixed, be also provided with pad 8 between described gland 1 and nut 7.
Further, some refuses operationally produced to make equipment or bubble are discharged, and described gland 1 is also provided with leak holes 11.
Further, in order to reach better sealing effect, the position that described axle sleeve 3 contacts with gland 1 is provided with seal ring 4.
Further, in order to reach better sealing effect, described axle sleeve 3 madial wall is provided with axle sleeve O and encloses 2.
The metal backup shoe 1 of split is built with the carbocyclic ring 9 of split, carbocyclic ring 9 is, socket is utilized to work in coordination, carbocyclic ring 9 outer ring be enclosed with Elastic medium 10, the thrust utilizing Elastic medium 10 resiliently deformable to produce makes carbocyclic ring 9 have one to the pressure in axle center, and this pressure makes gland 1 fit together with middle axle sleeve 3, utilizes the thrust-compensating of Elastic medium 10, make carbocyclic ring 9 and axle sleeve 3 remain fit-state closely, this faying surface is exactly the rubbing surface of motive sealing; Carbocyclic ring 9 is designed to quick condition, the equipment axis slight circular runout produced that is in operation can be absorbed by carbocyclic ring, while extension device working life, also make carbocyclic ring 9 be close to axle sleeve 3 all the time, reach good sealing effect; Meanwhile, some other auxiliary seal means can also being utilized, as set up the means such as O type circle, guaranteeing that sealing effect reaches the optimum state; In addition, by means of transmission system, as driven screw 5, axle sleeve 3 is rotated, and meanwhile, carbocyclic ring 9 keeps motionless, and make to produce relative displacement between axle sleeve 3 and carbocyclic ring 9, this relative displacement is exactly the relative displacement between motive sealing fastness; Setting up seal ring 4 at the madial wall of axle sleeve 3 with needing the equipment contacting point sealed, the sealing effect of axle sleeve can be made better; The position contacted with gland 1 at axle sleeve 3 is provided with seal ring 4, and axle sleeve 3 can be made better with the sealing effect of gland 1.
In addition, described in the utility modelly state carbon ring sealing structure also to have active length shorter, the advantage of compact structure.
