Put）Efficiency, cause to waste and pollute environment.Leakage is a small amount of phenomenon for not doing useful work fluid leaked out of crossing the border at sealing.
In sealing, static seal and dynamic sealing are divided into the presence or absence of relative motion according to sealed coupling face.In dynamic sealing side
In method and structure, more sealings for revolute and the pair that reciprocatingly slides, such as the sealing of axis class and sealing piston of hydraulic cylinder, this sealing
It is being sealed two peripheries of coupling.It is secondary, it is necessary to office on circular arc coupling surface when forming sliding motion on arc surface
When portion position seal is rotated or moved linearly sealing, existing sealing device and method cannot be met the requirements.
The content of the invention
The technical problem to be solved by the present invention is to provide a kind of mulit-lip seal ring and sealing device, to realize circular arc
The dynamic sealing of sliding surface kinematic pair.
The technical solution of the utility model is：A kind of mulit-lip seal ring and sealing device, including elastic seal ring 1, sealing
Groove 2, lubricating grease 3, arc surface fixing piece 4, arc surface rotating member 5, liquid flow hole I 6, liquid flow hole II 7；Elastic seal ring 1 is installed on
In seal groove 2, seal groove 2 is opened on 5 sliding surface of arc surface rotating member, and lubricating grease 3 is applied to elastic seal ring 1 and consolidates with arc surface
Between determining part 4, for arc surface rotating member 5 by clearance fit loaded in arc surface fixing piece 4, seal is circle.Liquid stream passes through
Liquid flow hole I 6 flows into liquid flow hole II 7 or flows into liquid flow hole I 6 by liquid flow hole II 7, and it is blind that liquid flow hole II 7 can also form through-flow sealing
Hole.
The elastic seal ring 1 is more lip elastic seal rings, including sealing lip V 16, sealing lip VI 17, sealing lip VII 18,
Sealing lip VIII 19, sealing lip Ⅸ 20；
More lip elastic seal ring section configurations are square, and four square angles sentence the 1/3 square length of side and are
Diameter rounded corner forms sealing lip V 16, sealing lip VII 18, sealing lip VIII 19, sealing lip Ⅸ 20, square top center respectively
Arc-shaped sealing lip VI 17 is equally formed as diameter using the 1/3 square length of side, sealing lip VI 17 respectively with sealing lip V 16 and
Sealing lip VII 18 connects；
Lip groove is formed between the sealing lip V 16 and sealing lip VI 17, between sealing lip VI 17 and sealing lip VII 18,
Lubricating grease 3 is applied in the lip groove of more lip elastic seal rings.
More lip elastic seal ring section configurations are square, in the two sides and base of square, equipped with midpoint
For the center of circle, 1/2 length of side be diameter, inside circular arc, sealing lip at three circular arcs and square four angles is round and smooth to be connected.
The principle of the utility model is：When liquid flow hole I 6 or liquid flow hole II 7 have pressure liquid stream, circular sliding surface fixing piece
I.e. with the presence of leakage between 4 and arc surface rotating member 5.Pressure liquid stream acts on sealing lip V 16, realizes level-one dynamic sealing, level-one
Dynamic sealing leak pressure liquid stream acts on sealing lip VI 17, realizes two level dynamic sealing, the effect of two level dynamic sealing leak pressure liquid stream
In sealing lip VII 18, three-level dynamic sealing being realized, being effectively equivalent to three-level O-ring seals dynamic sealing, lubricating grease 3 is mainly used for liquid
Flow medium is low-viscosity (mobile) liquid, the poor occasion of lubricity.On 2 slot bottom of seal groove, pressure liquid stream acts on sealing lip VIII 19,
Realize level-one static seal, level-one static seal leak pressure liquid stream acts on sealing lip Ⅸ 20, realizes two level static seal, due to sealing
Lip Ⅸ 20 is bonded with two right-angle sides of seal groove 2, and equivalent to two-stage O-ring seals static seal, actually static seal is also three-level O
Shape sealing ring static seal.
The beneficial effects of the utility model are：
（1）Sealing ring is high equivalent to multiple seal with O ring, sealing reliability.
（2）Sealing ring dynamic sealing lip groove can increase and decrease according to seal pressure, and seal pressure grade is high.
（3）Sealing ring pre compressed magnitude is big, and sealing compensation is good.
（4）Sealing ring pressure side, two sealing lip pressure joint opens are big, and sealing paste is got togather, good airproof performance.
（5）Sealing ring static pressure side, the two sealing lip amounts of actuating are big, and sealing paste is got togather, good airproof performance.
（6）Sealing ring can realize lubrication sealing.
（7）Sealing ring is sealed available for bidirection press.
（8）Sealing ring can be used for flat seal, or circle rotation, reciprocation sealing.
