The axial centre position of slot, the installation base is equipped with threaded hole, and the outer surface of the sealing ring body is additionally provided with embedded groove,
The inside of the embedded groove and disconnected kerf is equipped with strengthening rib strip, and the upper surface of the sealing ring body is additionally provided with several uniform
The hollow cavity of distribution, the hollow cavity is interior to be equipped with elastic film, and suction is additionally provided between the hollow cavity and elastic film
Water gelatin ball.
As the utility model a preferred technical solution, all hollow cavities are to be arranged concentrically.
As the utility model a preferred technical solution, the lower surface edge of the sealing ring body is also arranged with resistance to
Warm rubber ring, the outer surface of the temperature resistant rubber circle also are provided with the soft raised item of rubber.
As the utility model a preferred technical solution, the edge of the elastic film is integrated with hollow cavity
Structure, and several equally distributed ventilative suction holes are additionally provided on the surface of the elastic film.
Compared with prior art, the utility model has the beneficial effects that the utility model stable structure, in high pressure draught
Under environment, by the way that multiple compensatory gasket is arranged, stable deformation space can be provided for sealing ring, to increase to sealing ring
Support function, the generation different distortion degree after preventing sealing circle body to be pressurized, in addition adds water swelling gelatin, to can be improved
Sealing ring is in the absolutely gas-tight used.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As depicted in figs. 1 and 2, the utility model provides a kind of sealing ring, including sealing ring body 1, the sealing ring
The inner hub location of ontology 1 is equipped with annular center hole 2, and circumferential position of the sealing ring body 1 in annular center hole 2 is equipped with
Several soft raised items 3 of equally distributed rubber, sealing ring body 1 when in use, the soft raised item 3 of rubber can increasing friction force, mention
Fastness when height installation.
Several circumferentially distributed installation bases 4, the installation base 4 are equipped with along the outer edge of the sealing ring body 1
Radial center position be equipped with disconnected kerf 5, the axial centre position of the installation base 4 is equipped with threaded hole 6, sealing ring body 1
It can be fixedly installed togather by threaded hole 6 and other objects, to improve the stability of sealing ring body 1 when in use.
The outer surface of the sealing ring body 1 is additionally provided with embedded groove 7, the inside peace of the embedded groove 7 and disconnected kerf 5
Equipped with strengthening rib strip 8, the strengthening rib strip 8 can reduce deformation of the sealing ring body 1 when heated, in the environment of high-pressure fluid
Under, since the external sealing ring bodies of 8 pairs of strengthening rib strip have a stronger support effect, thus with the deformation of the contact surface of high-pressure fluid compared with
It is small, it effectively prevent because of the different distortion degree after being pressurized between sealing ring body 1 and strengthening rib strip 8, and there is sealing ring body 1
It is unevenly distributed phenomenon with the interface pressure of sealing surface, improves sealing effect, to can reach better seal effect.
