Description
Technical field
The utility model relates to dynamic sealing technology field, particularly a kind of seal assembly.
Background technique
As everyone knows, between rotating component and housing, conventionally need to adopt Sealing to seal, for example, in the pivotal position between the stirring shaft and housing of stirrer, between the rotating shaft and housing of beater, between the rotating shaft and housing of rig, between the screw rod of screw pump and housing etc., or the to-and-fro motion position between plunger and the housing of plunger pump, all needs to arrange dynamic sealing.
But current dynamic seal structure is comparatively single, be mostly just independent outside framework oil seal or packing seal, this single sealing means only can meet the seal request of short time, higher for seal request, and the position of growing service time, single sealing configuration can not meet the demands far away.
Therefore, how can effectively improve the sealing effect of dynamic seal (packing), and be the technical problem that current those skilled in the art need solution badly the working life that can effectively extend dynamic seal (packing).
Model utility content
The purpose of this utility model is to provide a kind of seal assembly, to can effectively improve the sealing effect of dynamic seal (packing), and can effectively extend the working life of dynamic seal (packing).
For solving the problems of the technologies described above, the seal assembly that the utility model provides, for dynamic seal (packing), and sealing assembly comprises outside framework oil seal section and the packing seal section adjacent with described outside framework oil seal section.
Preferably, described packing seal section comprises:
Stuffing box;
Be arranged at the Sealing in described stuffing box;
Be connected with described stuffing box bolt, and for compressing the gland of described Sealing.
Preferably, described Sealing is packing_seal circle.
Preferably, described packing_seal circle comprises multiple, and multiple described packing_seal circle is superimposed with each other.
Preferably, also comprise the oil storage annular groove being arranged between described outside framework oil seal section and described packing seal section.
Preferably, also comprise the pump nozzle being connected with described oil storage annular groove.
Preferably, described outside framework oil seal section comprises multiple outside framework oil seals that are superimposed with each other.
As can be seen from the above technical solutions seal assembly provided by the utility model comprise outside framework oil seal and with outside framework oil seal section and the packing seal section adjacent with outside framework oil seal section, two kinds of sealing means combinations will effectively improve the sealing effect of motive sealing, prevent the generation of leakage accident, and the combination of two kinds of sealing means can also be mutually as a supplement, after a kind of seal structure damage, seal failure be can't cause, thereby the working life of sealing and the reliability of sealing effectively improved.
Brief description of the drawings
The cross-sectional view that Fig. 1 is the seal assembly that provides in the utility model embodiment;
Fig. 2 is the right TV structure schematic diagram of the seal assembly shown in Fig. 1.
Wherein, 1 is outside framework oil seal section, and 2 is packing seal section, and 3 is pump nozzle, and 4 is oil storage annular groove;
11 is outside framework oil seal, and 21 is stuffing box, and 22 is packing_seal circle, and 23 is gland, and 24 is bolt.
Embodiment
Core of the present utility model is to provide a kind of seal assembly, to can effectively improve the sealing effect of dynamic seal (packing), and can effectively extend the working life of dynamic seal (packing).
In order to make those skilled in the art person understand better the utility model scheme, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Please also refer to Fig. 1 and Fig. 2, the cross-sectional view that Fig. 1 is the seal assembly that provides in the utility model embodiment, Fig. 2 is the right TV structure schematic diagram (partly cuing open figure) of the seal assembly shown in Fig. 1.
The seal assembly providing in the utility model embodiment, is mainly used in motive sealing, comprises rotating seal and reciprocating seal, concrete, and sealing assembly comprises outside framework oil seal section 1 and the packing seal section 2 adjacent with outside framework oil seal section 1.
As shown in fig. 1, the common formation seal assembly of outside framework oil seal section 1 and packing seal section 2, the combination of two kinds of sealing means will make both sealing effect stacks, thereby effectively improve the sealing effect of whole seal assembly, prevent the generation of leakage accident, and the combination of two kinds of sealing means can also mutually as a supplement, can't cause seal failure after a kind of seal structure damage, thereby effectively improve the working life of sealing and the reliability of sealing.
As shown in fig. 1, in outside framework oil seal section 1, be provided with outside framework oil seal 11, packing seal section 2 in the utility model in disclosed seal assembly comprises stuffing box 21, Sealing and gland 23, wherein stuffing box 21 is for carrying Sealing, Sealing is filled in stuffing box 21, and be pressed on the bottom of stuffing box 21 by gland 23, to realize sealing, between gland 23 and stuffing box 21, be connected by bolt 24.And after the Sealing in stuffing box 21 is worn, can also be by 24 the mode of continuing to tight a bolt again by Sealing press seal.
Preferably, Sealing in above-described embodiment is packing_seal circle 22, as shown in fig. 1, in order to ensure the effect of packing_seal, in the utility model embodiment in disclosed seal assembly, packing_seal circle 22 comprises multiple, and the setting that is superimposed with each other of multiple packing_seal circle 22, and is glanded 23 compressions.
Because motive sealing is applied in rotatablely move position or to-and-fro motion position, thereby the action of moving element easily causes the wearing and tearing of Sealing, for this reason, in the utility model embodiment, also between outside framework oil seal section 1 and packing seal section 2, be provided with oil storage annular groove 4, in oil storage annular groove 4, be provided with the butter of lubricated use, the setting of oil storage annular groove 4 not only can form sealing position lubricated, and the oil film that can also form by butter further improves the sealing effect of seal assembly simultaneously.
More preferred, can also on seal assembly, be provided with the pump nozzle 3 communicating with oil storage annular groove 4, pump nozzle 3 can be communicated with the oiling equipment that keeps certain pressure, continues to the object of oil storage annular groove 4 interior fuel feeding thereby realize.
In order to ensure sealing effect, multiple outside framework oil seals 11 also can be set in outside framework oil seal section 1, and multiple outside framework oil seal 11 is superimposed with each other, as shown in fig. 1.
In the utility model, disclosed seal assembly has not only effectively improved sealing effect, has improved working life, but also makes the dismounting of seal assembly and maintenance become simple and easy to do.
Above seal assembly provided by the utility model is described in detail.Applied specific case herein principle of the present utility model and mode of execution are set forth, above embodiment's explanation is just for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
