Abstract
The utility model relates to a special-shaped sealing device. The special-shaped sealing device comprises a sealing ring body, wherein the upper end face of the sealing ring body is an arc surface, bosses are arranged on the two sides of the sealing ring body, the sealing ring body and the bosses are integrally formed, containing grooves are formed between the bosses and the sealing ring body, sealing check rings are placed in the containing grooves, and the upper top faces of the sealing check rings are flush with the top end of the arc surface. According to the special-shaped sealing device, the sealing check rings and the sealing ring are creatively combined for use, the sealing effect can be effectively improved, excursion between the sealing check rings and the sealing ring is prevented, the service life of the sealing device is prolonged, and meanwhile dry friction is avoided.
Description
Technical field
The utility model relates to technical field of sealing technology, relates in particular to a kind of profiled seal device.
Background technique
The effect of sealing is exactly that the gap that makes mating face seals, isolates or cuts off leakage, and the resistance of increase in leakage, to reduce or to stop leakage.Under certain pressure, blocking-up is revealed and can be accomplished completely, and this will cause kinematic pair in dry condition, make frictional force excessive.According to sealing coupling part, have or not relative movement in machine run, sealing is divided into static seal and motive sealing, current seal ring is all independent use, easily causes to a certain extent seal failure, makes sealing effect variation, and sealability reduces.
Model utility content
The utility model, in order to overcome deficiency of the prior art, provides a kind of profiled seal device, can effectively improve sealing effect.
The utility model is to be achieved through the following technical solutions: a kind of profiled seal device, comprise sealing circle body, the upper-end surface of described sealing circle body is arc surface, in the both sides of sealing circle body, is provided with boss, between described boss and sealing circle body, form containing groove, in described containing groove, be placed with Sealing shield ring.
As optimal technical scheme of the present utility model, described sealing circle body and boss are one-body molded.
As optimal technical scheme of the present utility model, the upper end face of described Sealing shield ring flushes with the top of arc surface.
As optimal technical scheme of the present utility model, the difference d of the upper end face of described Sealing shield ring and the upper end face of boss is 5mm.
Compared with prior art, the beneficial effects of the utility model are: the utility model creatively combines use by Sealing shield ring and seal ring, can effectively improve sealing effect, prevent from being offset between Sealing shield ring and seal ring, improve the working life of seal arrangement, avoid occurring dry friction simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-seals circle body; 2-boss; 3-containing groove; 4-Sealing shield ring; 10-arc surface.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of profiled seal device, comprises sealing circle body 1, and the upper-end surface of described sealing circle body 1 is arc surface 10, in the both sides of sealing circle body 1, is provided with boss 2, and described sealing circle body 1 is one-body molded with boss 2.
Between described boss 2 and sealing circle body 1, form containing groove 3, in described containing groove 3, be placed with Sealing shield ring 4, the upper end face of described Sealing shield ring 4 flushes with the top of arc surface 10, and the difference d of the upper end face of described Sealing shield ring 4 and the upper end face of boss 2 is 5mm.By Sealing shield ring and seal ring are combined to use, can effectively improve sealing effect, prevent from being offset between Sealing shield ring and seal ring, improve the working life of seal arrangement, avoid occurring dry friction simultaneously.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
