Abstract
The utility model provides a rectangular composite gasket which comprises a rectangular rubber substrate, an inner side surface of the rectangular rubber substrate and an adhered plastic lining. The plastic lining can be made of polyfluortetraethylene or polyether-ether-ketone. The rectangular composite gasket has the advantages of small friction coefficient, good wear resistance and long service life.
Description
Affiliated technical field
The utility model relates to a kind of seal ring, especially a kind of rectangle composite sealing ring.
Background technique
Deficiencies such as the seal ring that present mechanical industry is used is generally made by homogenous material, as common rectangular rubber circle, when being used for motive sealing, exists frictional force big, wears no resistance, and working life is short.
Summary of the invention
Big in order to overcome existing rectangular seal frictional force, wear no resistance, deficiency such as working life is short, the utility model provides a kind of rectangle composite sealing ring.
The technological scheme that its technical problem that solves the utility model adopts is, a kind of rectangle composite sealing ring comprises the rectangular rubber substrate, the inner side surface of rectangular rubber substrate, and also gummed has the plastic lining face.
The plastic lining face can be a teflon, also can be polyalkylene polyether ether ketone.
The beneficial effects of the utility model are that friction ractor is little, and wear resistance is good, long service life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is embodiment's a tectonic maps.
Among the figure: 1. rectangular rubber substrate; 2. plastic lining face.
Embodiment
As shown in Figure 1, a kind of rectangle composite sealing ring comprises rectangular rubber substrate 1, the inner side surface of rectangular rubber substrate 1, and also gummed has plastic lining face 2.Plastic lining face 2 can be a teflon, also can be polyalkylene polyether ether ketone.Because adopt plastics as surface of contact, so wear resistance is good, friction factor is little, long service life.
Claims (3)
1, a kind of rectangle composite sealing ring comprises the rectangular rubber substrate, it is characterized in that: at the inner side surface of described rectangular rubber substrate, also gummed has the plastic lining face.
2, rectangle composite sealing ring according to claim 1 is characterized in that: at described plastic lining face is teflon.
3, rectangle composite sealing ring according to claim 1 is characterized in that: at described plastic lining face is polyalkylene polyether ether ketone.
