Abstract
The utility model provides a rectangular double-layer sealing ring, including a rectangular rubber matrix, the internal side of which has a polytetrafluorethylene lining, the rectangular rubber matrix is glued with the polytetrafluorethylene lining by adhesive closely. The rectangular double-layer sealing ring has the advantages that the friction coefficient is low, the wearing resistance is good, and the service life is long.
Description
Affiliated technical field
The utility model relates to a kind of seal ring, especially a kind of rectangular double-layer seal ring.
Background technique
Deficiencies such as the present mechanical industry seal ring that sealing is used as the axle class generally adopts rubber to make, and exists friction ractor big when motive sealing, wears no resistance, and working life is short.
Summary of the invention
Exist friction ractor big in order to overcome existing seal ring, wear no resistance, deficiency such as working life is short, the utility model provides a kind of rectangular double-layer seal ring.
The technological scheme that its technical problem that solves the utility model adopts is, a kind of rectangular double-layer seal ring, comprise the rectangular rubber matrix, the inner side surface of rectangular rubber matrix also has teflon lining face, and rectangular rubber matrix and teflon lining face closely glue together by viscose glue.
The beneficial effects of the utility model are that friction ractor is low, 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 matrix; 2. teflon serves as a contrast face.
Embodiment
As shown in Figure 1, a kind of rectangular double-layer seal ring comprises rectangular rubber matrix 1, and the inner side surface of rectangular rubber matrix 1 also has teflon lining face 2, and rectangular rubber matrix 1 and teflon lining face 2 closely glue together by viscose glue.Rectangular rubber matrix 1 has suitable elasticity, good seal performance, and teflon lining face 2 contacts with the movement parts of sealing configuration, and it is little to have a friction ractor, and wear resistance is good, the advantage of long service life.
