Abstract
The utility model relates to a sealing arrangement. The structure of the utility model comprises a casing body, a gland and a sealing sleeve. The utility model is characterized in that a seal cavity is reserved between the gland and the sealing sleeve, sealant is injected in the seal cavity, a sealant charging hole communicated with the seal cavity is opened on the gland, and every component can be manufactured by punching injection molding or turning. The arrangement not only can be individually installed at the position which needs to be sealed, but also can be installed with a valve, an axial pump and the like all in one in utilization. The arrangement can be applied to the dynamic seal and the static seal structures, and is a preferably ideal sealing arrangement with wide application range, simple structure and reliable effect.
Description
Technical field
The utility model relates to a kind of seal arrangement, particularly a kind of not seal arrangement of leakage sealed body that is applicable to.
Background technique
Disclosed in the prior art seal arrangement divides contact-type and contactless.There is wear problem in contact-type, and " O " type stuffing box gland is fixed by spring pressure, needs the periodic replacement Sealing, as producing bigger harm because of the inordinate wear meeting.Contactless gap throttling groove type, the mazy type etc. of mainly containing.Throttling groove type in gap as medium, though there are not the machinery wearing and tearing, has leakage with lubricating grease, and sealing effect is bad.Labyrinth sealing, with lubricating grease as medium, good sealing effect, but have big gauging to be stored in the sealing position, bigger because of moving part and quiet gap, because of centrifugal action, will unavoidably have oil to throw away, simultaneously, sealing configuration is complicated, consider dynamic equilibrium problems.
Summary of the invention
The purpose of this utility model is to provide a kind of seal arrangement, and this device stuffing box gland strong adhesion is not easy to wear, eliminate vibrations and noise, be fitted to seals such as various bearings, valve, fluid switch, oil cylinder, or be made of one use, realize sealing purpose with them.
The purpose of this utility model realizes in the following manner.A kind of seal arrangement is made of housing, gland and stuffing box gland, is characterized in: between gland and stuffing box gland Seal cage is arranged, have the injecting hole that communicates with Seal cage on gland, sealing compound is arranged in Seal cage.
For make contact between stuffing box gland and operation piece (as axle) tightr, with the stuffing box gland inboard of axle junction on have the plurality of tooth-shaped groove, this design can make leakage agent form eddy current at this and circle round, and reduces infiltration forward.
At the stuffing box gland root, have the garden annular groove, can strengthen sealing compound " extruding " power to stuffing box gland, sealing suburb fruit is better.
In the utility model, stuffing box gland can be single, two, also can be made of one two middle connections.Modes such as the available punching press of whole device, injection moulding, turning process, and can select metallic material for use, and are also available nonmetal as plastic processing.
Said sealing compound can be a liquid in the utility model, also can be solid material, and available organic substance also can be selected inorganic material for use, during use, by the injecting hole, squeeze in the Seal cage with injection gun, again with port closing, after this, regularly inject sealing compound according to circumstances and get final product after being full of.
The utility model can be used for movable sealing structure, also can be used for static seal structure, can be made of one, and also can assemble separately.
The technological progress that the utility model is obtained is:
1, stuffing box gland rapid wear ring is not eliminated vibrations and noise, and the running resistance is little, flexible, is applicable to that various being strictly on guard against leak vibrations and noise, and the sealing of each stage pressure lower seal body, applied range.
2, combiner variation, cost reduces greatly.
3, utilize the pressure of sealing compound, can enhanced leaktightness and reduce its loss, increased the reliability of seal arrangement.
4, the design of the cavity between gland and stuffing box gland, and be marked with sealing compound, therefore the pressure that bears improves greatly.
Description of drawings
What Figure of description 1 provided is the example structure schematic representation of the utility model seal arrangement.
Number in the figure is expressed as follows:
1, axle 2, bearing 3, housing 4, gland 5, injecting hole 6, Seal cage 7, stuffing box gland 8, groove 9, serrate slot 10, sealing compound
Embodiment
The embodiment who provides below in conjunction with accompanying drawing is further described the utility model.
Referring to Fig. 1, a kind of seal arrangement, being used for axle sealing structure, is by housing 3, and gland 4 and stuffing box gland 7 are formed, it is characterized in that: 7 of gland 4 and stuffing box glands have Seal cage 6, on gland 4, have the injecting hole 5 that communicates with Seal cage 6, sealing compound 10 is arranged in the Seal cage 6, have serrate slot 9 in inboard with the stuffing box gland 7 of axle 1 junction, in addition, have toroidal cavity 8 at stuffing box gland 7 roots.Its fit system is such: axle 1 is done high speed rotating or fore and aft motion, sealing compound 10 usefulness injection device high pressure inject in the Seal cage and evenly and distribute, do not have and leak, because of big pressure makes elastic stuffing box gland 7 and the axle 1 no gap that closely cooperates, as long as sealing compound is also regularly injected in the sealing of injecting hole according to circumstances, just enough pressure can be guaranteed to have in the chamber, thereby sealing effect can be realized.
Claims (3)
1, a kind of seal arrangement, constitute by housing (3), gland (4) and stuffing box gland (7), it is characterized in that: between gland (4) and stuffing box gland (7) Seal cage (6) is arranged, on gland (4), have the injecting hole (5) that communicates with Seal cage (6), sealing compound (10) is arranged in the Seal cage (6).
