Abstract
The utility model relates to an MBS shaft used sealing ring, which includes a Y-shaped lip mouth sealing ring and two lip mouths arranged on one side of the Y-shaped lip mouth sealing ring, wherein a triangular groove is arranged in the front end of the Y-shaped lip mouth sealing ring. The MBS shaft used sealing ring adopts the combined seal ring, changes the problem that the previous product changes along with the temperature and leaks easily under the conditions of low pressure or vacuum, and is wear-resistant, impact-resistant and extrusion-resistant, so that the sealing effect is good.
Description
Technical field
The present invention relates to the Sealing field, be specifically related to a kind of MBS axle and use seal ring.
Background technique
Along with domestic economy constantly develops; The national life level improves constantly; The industrial automatization of numerous domestic industrial and mining enterprise further improves; And sealed product performer key player in industrial automation, the quality of sealed product quality plays key effect aspect the fluid dynamic transmission in industrial automation.Particularly in concerning the national great type equipment of national economy, stable, the quality of sealed product performance reliable and to the tolerance of various flowing mediums all is very important.Simultaneously, in the great at home type key equipment, adopt the Sealing of developed countries import; Not only cost an arm and a leg; And the arrival cycle is long, during the apparatus maintenance transformation, causes heavy losses to enterprise, causes severe contamination to environment; Destroy natural, ecological, and imported product can not be dealt with problems sometimes.
At present, maximum Sealing of using on the market is an O type circle, and it produces prestressing force by the extrusion-deformation of when assembling and reaches sealing effect.Its feature is: simple in structure, withstand voltage height, volume are little.But because wearing and tearing are big in the movement process, be in deformation state for a long time, be prone to produce permanent deformation forfeiture elasticity, operating life is short.Though mostly adopt combining form now, be basic resilient support promptly with 0 type circle, add the seal ring of a material that usefulness is wear-resisting, corrosion resistant is lit up in 0 type circle outer ring, with the purpose that realizes increasing the service life.But, be that the combined seal ring that base growth is got up can not keep good sealing effect the long period equally with 0 type circle owing to keep away the deadly defect that produces permanent deformation in the unavoidable use as 0 RunddichtringO of basic resilient support.So adopt the liquid of this type sealing technique, pneumatic cylinder shorter working life.
Summary of the invention
Goal of the invention: the objective of the invention is to overcome the deficiency of above-mentioned prior art, provide a kind of shock-resistant, anti-extruding, the axle of good sealing effect is used combined seal ring.
Technological scheme: in order to solve the problems of the technologies described above, axle of the present invention is used combined seal ring, and it comprises Y shape lip seal circle, and two lips that are located at this Y shape lip seal circle one side, and said Y shape lip seal circle front end is provided with triangular groove.
The shape of said two lips is respectively triangle and semicircle.
Said Y shape lip seal circle is a polyurethane.
The present invention is shock-resistant, anti-ly extrude, compressive strain is little, owing between the sealing lip extra oiling agent is arranged, prevented dry friction and wearing and tearing greatly, improved the sealability under the zero pressure, the fabulous entering that prevents outside air.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: adopt the seal ring of combining form, changed former product with temperature variation and under low pressure or vacuum condition the problem of leakage easily; It is wear-resisting; Shock-resistant, resist and extrude good sealing effect.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Wherein:
1, Y shape lip seal circle; 2, lip; 3, groove
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
As shown in Figure 1, combined seal ring of the present invention, it comprises Y shape lip seal circle 1, and two lips 2 that are located at these Y shape lip seal circle 1 one sides, said Y shape lip seal circle 1 front end is provided with triangular groove 3; The shape of said two lips 2 is respectively triangle and semicircle; Said Y shape lip seal circle 1 is a polyurethane; The present invention is shock-resistant, anti-ly extrude, compressive strain is little, owing between the sealing lip extra oiling agent is arranged, prevented dry friction and wearing and tearing greatly, improved the sealability under the zero pressure, the fabulous entering that prevents outside air.The present invention adopts the seal ring of combining form, has changed the problem of former product with temperature variation and easy leakage under low pressure or vacuum condition, and it is wear-resisting, and is shock-resistant, resists and extrudes good sealing effect.
